How to look at the pressure test of floor heating pipes, and how much time does it take to test the

Judging from the **, the floor heating in your home has been installed, and the pressure should have been tested, and there is no need to test the pressure again.

Let's get to know the underfloor heating in your home first.

The upper row of pipes is the water inlet pipe and water divider, the lower row of pipes is the return pipe and the water collector, the valve on the left side of the upper row is the water inlet valve, which is integrated with the Y-shaped filter, and the lower valve is the return valve.

The two things on the right, one red and one blue, are the drain valve knobs, and the thick round body above is the automatic exhaust valve, which is also called "running wind", and its function is to remove the air in the pipe.

Before municipal heating, you need to disconnect from the common pipe (close the two valves on the left), slowly open the blue drain valve on the right, observe the pressure gauge, and turn off the drain when the descent is almost 0. Then use a wrench to open the filter drain port on the left side of the valve on the upper pipeline, remove the dirt or check whether there is dirt, and close the sewage outlet after cleaning.

Loosen the small nut at the top of the exhaust valve on the red and blue on the right counterclockwise to make the exhaust smoother, and then open the upper and lower valves at the left end to connect the floor heating system of your home with the public pipeline, and observe whether the pressure gauge has been restored, and the recovery indicates that the public pipeline has been connected.

Finally, slowly open the red and blue drain valve at the right end at the same time, and the opening should not be too large or too small, so that the water can flow to the end and discharge the air in the pipe. If there is no leakage at the nut of the exhaust valve, it can be not closed, if there is a leak, tighten it clockwise, and relax it again during municipal heating, so that the circulating water flow can discharge some more gas.

The three gray knobs on the water collector are the water flow control valve, which rotates counterclockwise to increase the water flow, and vice versa, the water flow is large and the temperature is high, and the temperature is weak and low. If this happens, you can turn the lower diameter of the gray knob counterclockwise (connecting nut), remove the knob, and then use the handle of a screwdriver to knock the stem along the stem axial direction to loosen it and restore it to an adjustable state, and then install the knob.

See**. I am the pioneer of boiler-free water floor heating, which has less investment and low maintenance costs, which is suitable for ordinary working families. If you want to know about boiler-free water floor heating, you can "boiler-free water floor heating".

Check to see if there is any water seepage around.

After the floor heating paving is completed, it is necessary to test the pressure, the first pressure to 8 kg, wait for 20 30 minutes, at this time the main thing is to observe whether there is leakage at the interface of each floor heating pipe of the water collector, if there is no leakage, the pressure can be reduced to 6 kg.

Then, the pressure of 6 kg within 24 hours, the pressure not less than 4 kg is qualified.

Finally, this pressure can be maintained until the boiler is installed, and if the pressure is zero in the middle of the process, it is immediately checked.

The pressure of the underfloor heating system should be around bar). Before the pressure test, it is usually necessary to drain the air in the floor heating piping system first, and then use a special pressure test equipment to test the pressure until the pressure reaches about it.

It is important to note that too high or too low pressure test pressure may affect the normal operation of the floor heating system. If the pressure is too high during the pressure test, it may cause water leakage at the pipe connection; If the pressure is too low, there may be a leak or other problem. Therefore, before the pressure test, it is necessary to check whether the posture cover of the pipes, valves, pumps and other components of the floor heating system is damaged to ensure the safety and accuracy of the pressure test.

In addition, it is also necessary to remove the residual air in the system in time after the pressure test to ensure the normal operation of the floor heating system.

Nowadays, floor heating is a very important heating equipment for many northerners, but the installation of floor heating is more complicated, and after the installation of floor heating, it is also necessary to carry out the later pressure test work of floor heating, so how much is the pressure test pressure of floor heating? What should I pay attention to in the pressure test of floor heating? Let's take a look.

1. What is the normal pressure test pressure of floor heating?

The normal pressure test pressure of floor heating is that the floor heating pressure test is to fill the floor heating system with water by using a water pressure pump, and at the same time discharge the air from the system pipeline, and then carry out the pressure test.

2. What should be paid attention to in the pressure test of floor heating?

1. When testing the pressure of floor heating, it is necessary to first flush the water separator, the main supply and return pipes other than the water collector, and then flush the indoor heating system, and carefully check the laying of the indoor heating pipe.

2. Before the floor heating pressure test, it is necessary to safely and effectively protect the pressure test pipes and components.

3. When testing the pressure of floor heating, it is necessary to pay attention to the water injection speed, which should not be too fast, and the tightness of each loop needs to be carefully checked after filling with water.

4. After five minutes of floor heating pressure test, it is necessary to test whether each loop is sealed again, observe the pressure gauge, if the pressure drop is greater than within ten minutes, it is qualified.

5. When the floor heating pressure test is carried out in winter, it is necessary to do a reliable pipeline anti-freezing protection measures, and the water in the pipeline should be blown clean and dried after the floor heating pressure test.

6. Choose the pipes of regular manufacturers, strictly monitor the fixed laying on site, lay a springboard when backfilling the heat storage protective layer, prohibit the ash on the pipe, and lay the wooden board when cutting the tiles, and prohibit making holes in the ground.

7. When using the floor heating system in the second year, it needs to be heated gradually in stages, and if the temperature is adjusted to the highest at one time, it will cause serious damage to the ground material and even the floor.

8. When the pressure of the floor heating is tested for the first time, it is necessary to make up the pressure in time, and it is normal to reduce the pressure by about 2 for the first time.

Summary: How much is the normal pressure test pressure of floor heating, and what needs to be paid attention to in the pressure test of floor heating, it is briefly introduced here, I hope it can help you, if you want to know more exciting content, please continue to pay attention to Qeeka Home.

The normal pressure test pressure of underfloor heating should be between to. During the pressure test, the pressure test time should be kept for no less than 10 minutes, and the pipes and joints should be observed for leakage to ensure that the sealing performance of the floor heating system is good. At the same time, before the pressure test, it is necessary to check whether the pipes and joints are firmly packed and sealed, and remove the air that may be present in the system to ensure the accuracy of the pressure test results.

If it is found that the floor heating system has problems such as leakage or unstable pressure, it should be repaired or replaced in time to ensure the normal operation of the floor heating system.

The normal pressure test pressure of floor heating is generally.

The normal pressure test pressure of floor heating is generally about megapascals). However, the specific pressure value of Fuldser oak needs to be determined according to the design parameters and materials of the floor heating system, and it is recommended that you consult a professional floor heating installation company or relevant technical personnel to ensure the normal operation of the floor heating system. At the same time, in order to ensure safety, it is necessary to operate in strict accordance with relevant regulations when testing pressure, and pay attention to preventing dangers caused by excessive pressure.

Summary. The floor heating water test is mainly to test whether the floor heating pipe is intact and whether there is water leakage, and the water test should be carried out in accordance with the standard: 1. Before the water pressure test, safe and effective fixing and protection measures should be taken for the pressure test pipeline and components, and the water pressure test pressure should be 1 5 times of the working pressure, not less than 0 6MPa.

The floor heating water test is mainly to test whether the floor heating pipe is in good condition, whether there is a leakage and the water is matched before the image, and the water test should be carried out in accordance with the standard: 1. Before the water pressure test, the pressure test pipeline and components should take safe and effective fixing and protection measures, and the water pressure test pressure should be 1 5 times of the working pressure, not less than 0 6MPa.

2. During the water pressure test, the water is slowly filled through the water separator, and the air in the pipeline is discharged at the same time. After filling with water, a water tightness check is performed. 3. Slowly increase the pressure with water, and the pure service room shall not be less than 5 when the pressure is raised, and after the pressure is boosted to the working pressure, the pressure is stabilized by 5, and the pressure is observed to be leaking, and the pressure drop within 10 is not more than 0 03MPa.

When conducting hydrostatic experiments in winter, feasible antifreeze measures should be taken.

What do you need to do when testing the water for floor heating 1, the floor heating test by the professional heating company staff to check whether the floor heating is in good condition, whether there is a water leakage problem, and need to pass the pressure test test, so as to detect whether the pressure standard is within a reasonable range, generally speaking, it can not be lower than 0 In the process of the experiment, it is necessary to inject water through the water separator, discharge the internal air, and then check the tightness. If the pressure is stable and there is no leakage, it is normal. 3. At the same time, it is also necessary to check whether the joint is loose and whether the control valve has been bitten to death.

The valve needs to be lubricated first to prevent rust from affecting the opening and closing. At the same time, if there are impurities or rust in the chain plexus in the filter, it needs to be cleaned and removed to ensure the normal use of the heating process, and there will be no water leakage or poor heating effect. For the water test step before floor heating, what does floor heating need to do when testing the water?

After reading the introduction, it should have been understood, in fact, for the floor heating in the water test should be buried is should be operated slowly, there must be personnel at home to guard, if there is a water leak or some other problems to communicate in time, by the heating company personnel to repair for you, in order to affect the later use.

1. First of all, the owner of the room should check whether the valve in the room can be opened and closed normally, because the floor heating is installed underground, and the water leakage of the ceiling should be checked, and the valve should be turned off if there is water leakage.

2. When checking the heating pressure in the main pipe at home, all the valves should be closed, otherwise it is easy to return orange water, which will cause the pressure of the pipe to be too large and easy to burst.

3. Check whether there are impurities such as sediment and stones in the pipeline, because these impurities can easily cause insufficient pressure in the pipeline.

4. The landlord determines the time of the floor heating pressure water test, and the general community will inform the time when the water test is notified, so that the landlord will close the water inlet valve and the return valve in advance.

5. Try to choose someone at home during the test, so that the water leakage can be dealt with in time, and once there is a water leakage, the main valve can be closed quickly.

<> "Most families in the north will choose floor heating, and before using floor heating, it needs to be suppressed, so what do you need to do to test the pressure of floor heating? What do I need to pay attention to? Let's take a look.

1. What needs to be done for floor heating pressure test.

1. Before the heating pressure water test, we must first check whether the opening and closing function of the floor heating valve is good, because the heating is installed underground, and also see if there is water leakage in the ceiling, if there is water leakage, turn off the valve immediately.

2. The heating pressure test is the main pipeline, so the valve should be closed before the pressure test, otherwise the water is easy to come from the pipe. If the valve is opened, the pressure of the main pipe is large, but the pressure of the main pipe is small, resulting in the main pipe sediment, stones and other impurities will flow into the pipe, so Qingxin must turn off the valve when testing the pressure, and then open it after the pressure test.

3. The door of the residential unit will generally be pasted with a notice of water test, and the owner should remember the time of water test, and turn off the water inlet valve and return valve of the heating pipe before testing the water. If you are not at home, it is recommended to leave the door for your neighbors and notify you in time if there is an accident.

2. What are the precautions for floor heating suppression?

1. Anti-freezing measures should be taken before the suppression test in winter.

2. Whether the pressure value is normal, the pressure difference is very important, if the pressure difference is larger, the faster the circulation, and the heat will be endless.

3. When the pressure test is carried out to inject water, pay attention to the water injection speed to be carried out slowly, and when the system is filled with water, it is necessary to check whether the sealing of each loop is normal in advance to prevent data inaccuracy.

4. After the pressure test is completed, the pressure can be relieved, and then the pressure test water can be released, and the corresponding records should be recorded and archived for future reference. If there is abnormal pressure or rapid pressure drop during the pressure test, the fault should be found and solved immediately.

Now that the winters in our country are getting colder and colder, many people have begun to lay underfloor heating in their homes. How normal is the pressure test pressure of floor heating? Next, let's take a closer look.

The floor heating has just been laid, and the pressure is applied after the construction is completed, and the pressure is replenished by using a manual injection pump, also called 6 kg). During the pressure test, it is recommended to retain the pressure for 24 hours. It can test the long-term pressure resistance of the pipeline.

The pressure will drop a little during the pressure test process, for example, the pressure will drop to even lower after a few hours, but it should not fall to 0. If the pressure gauge returns to 0, it should be determined that there is a water leak at the pipeline or interface in the case of ruling out damage to the pressure gauge. To sum up, the correct pressure test pressure should be about the left.

There are many ways to test the pressure of floor heating, and you can choose different methods to test the pressure.

1. Fill the floor heating system with water pressure pump, slowly increase the pressure to or twice the working pressure of the system, and observe whether there is any abnormal situation at any time during the pressure boosting process.

2. There is no leakage after one hour of stable pressure observation, and then continue to observe and observe for 15 minutes, and the pressure drop is & qualified. After the initial heating, the temperature is slowly increased, and the water temperature is controlled in the range of 25-30 for about 20 hours, and the water temperature can reach the normal range within 24 hours.
