How to open the valve of the heating pipeline, and how to open the heating valve

The heating temperature control valve is generally a ball valve, the valve has generally been adjusted before leaving the factory, there should be only two directions, the handle is open when it follows the pipe, and the rotation is 90 degrees to close.

1. From the front of the heating valve, it can be seen that there is a letter "O", which is the abbreviation of the English word "open", which means to open, and there is a counterclockwise arrow near the letter "O", that is, counterclockwise rotation to open the heating valve.

2. From the front of the heating valve, a letter "S" can be seen on the other side, as can be seen in the figure below, it is the abbreviation of the English word "shut", which means that it is closed, and you will also see a clockwise arrow pointing near the "S", and the heating valve will be closed if you rotate in the direction indicated by this arrow.

3. When the heating valve is opened, look at the valve from the front and rotate it in a counterclockwise direction to open the heating valve.

4. After using this method to open the valve, when the heating is not hot, you must check the room heater to open the valve and rotate it in a counterclockwise direction.

Open the valve clockwise.

Turn the handwheel, turn the handwheel counterclockwise when closing, and rotate it in place according to the opening and closing indication marks. The radiator can not change the position arbitrarily, nor can it release water from the system at will, because if the hot water is lost, the water temperature in the pipe network will decrease rapidly, resulting in a decrease in indoor temperature.

Open the manual bleed valve of each radiator to expel the air accumulated in the radiator, or open the exhaust valve of the gas collection tank installed on the top of the system to exhaust until each radiator is warmed up, the commissioning is complete, and once the commissioning is completed, the valve should be fixed and cannot be opened and closed at will.

When the heating valve is opened, the handle is in a straight line with the heating pipe.

If the handle is in a straight line with the heating pipe, the heating valve is open. However, if there is a 90-degree relationship between the handle and the heating pipe, then the heating valve is closed. Generally speaking, heating valves are marked with the words "open and open" and can be opened by rotating in a counterclockwise direction, while shut means closing and turning in a clockwise direction is closed.

What are the structures of heating valves?

1. a safety valve

It is mainly used to relieve pressure when the medium is overpressurized to protect equipment and systems. In some cases, the micro-opening hydraulic relief valve has been modified to be used as a system pressure regulator. There are many structural forms of safety valves, which are used in valve models"y"Denote.

2. Check valve

Also known as check valve or check valve, it allows the medium to flow in one direction, and if the pressure behind the valve is higher than the pressure before the valve, the check valve will automatically close. There are many types of check valves, mainly including: lifting type, swing type, etc.

The lifting valve has a large pressure loss, so it is rarely used in the new heat exchange station system. Used in valve models"h"Denote.

3. a globe valve

It is used to cut off the flow of medium, has a certain tempering performance, and has a large pressure loss, and is commonly used to cut off the flow of steam in the heating system, so the globe valve is generally used on the heating pipeline, and it is used in the valve model"j"Indicates a globe valve.

How to open the heating valve: Before the unified collapse heating, each household needs to do a heating test, that is, open the valve and adjust it to the appropriate position, so how to open the heating valve by itself? First, there are three ways to open the heating valve

1. If the valve is ball-shaped, then you only need to make the handle parallel to the pipe, and it can be opened, if the two are perpendicular, it means that it is closed. 2. If the valve is handwheel-shaped, turning to the left is closed, and rotating to the right is open. 3. Some valves are marked, open is open, and shout is closed.

After opening the valve, if you find that the heating pipe is not hot, then it is likely that there is air in the pipe, and you need to open the pressure relief valve to exhaust the air. If there is water seeping out, it means that the pipeline has ruptured, and you need to contact a professional to repair it.

How to open the heating valve:

Tool: Heating valve.

1. Open the entrance valve, which is generally controlled by the heating unit. If you don't owe heating bills, it will be turned on naturally, and if there is no sound of water filling in your own pipeline, you can contact the heating station in the community. Open the indoor pipeline valve, and generally set up the main valve at home when installing heating.

Locate the tubing valve location.

2. Distinguish which valve is water inlet and which is back water. Turn the inlet valve counterclockwise and open it completely by placing the handle of the valve parallel to the pipeline. Then open the birth valve in the same way.

If you can't tell the difference between the inlet and outlet valves, you can also open either one first and open the other.

3. If it is geothermal, turn on the water separator at the same time.

inlet and outlet valves. The corresponding upper and lower pipes are water inlet and water outlet, if the valve handle is horizontal, it should be rotated 90 degrees counterclockwise and the position parallel to the pipe is opened.

4. After all are opened, check whether there is water leakage, and close the water inlet valve in time if there is. If not, place a water separator or radiator.

The air shield is opened to drain the air inside, so as not to affect the quality of the heating.

Precautions for using heating

1. Be sure to ensure that the surrounding area of the radiator is ventilated, and the air must be in a state of circulation, because the radiator depends on radiation, as well as convection heat dissipation, if the heat dissipation is not good, then it will affect the service life of the radiator. Also, remember not to pile large objects around the radiator to avoid uneven temperature or unheated rooms.

2. Some friends will install radiators in every room at home, and they must remember to use them regularly, because if they are not used for a long time, the radiators will be corroded or oxidized, and they are prone to water leakage when they are used next time. The temperature of the room can be controlled at 18 degrees Celsius.

so that it will not consume too much energy, and it can also save everyone's living costs.

3. Do not add a cover outside, although it will look more beautiful, but it will affect the heat dissipation, which will also affect the heating effect.

To open the heating lock-off valve, you must use a magnetic key. And the operation method is very simple, first prepare a magnetic locking valve key; Then aim the "C-shaped" mark on the key at the corresponding mark on the valve; Finally, turn the key clockwise to open it.

2. What is the locking valve for heating pipes?

A heating pipe locking valve is a valve that can lock the valve position under certain conditions. In specific cases, they can be the same valve. For example, there is a kind of valve in plumbing engineering, which can be manually locked after being adjusted to a suitable opening by professionals, so that users cannot adjust it by themselves.

3. How to install the heating lock valve?

1. Install a locking valve opened by a magnetic card; The locking valve should be installed in the water supply pipeline of the circulating water, and the arrow on the valve should be consistent with the direction of the flowing water. In order to replace the valve during overhaul, a union should be added after the valve.

2. The central heating household circulating water return pipe should also be installed with valves, and ordinary valves can be used.

The household heating device can be divided into the building thermal inlet device and the indoor heating system home device. Filters should be installed for both the heat inlet supply and return pipes. The water supply pipe should be equipped with two filters, the first stage is coarse filtration in the direction of water flow, and the pore size of the filter screen should not be greater than that, and the second stage is fine filtration, and the filter screen specification should be the goal).

The indoor heating system of new buildings is generally located in the heating pipe well, and the renovation project should be set up in the special heating meter box in the stairwell, and the space for installation, inspection and maintenance of the heat meter is ensured.

1. From the front of the heating valve, it can be seen that there is a letter "o" (see the figure below for the position version), which is the abbreviation of the English word "open", which means to open. Note that there is also a counterclockwise pointing arrow near the letter "o", which means that the counterclockwise rotation opens the heating valve.

2. From the front of the heating valve, the other side can see a letter "S", which is the abbreviation of the English word "shut", which means to close, and rotating in the direction indicated by this arrow will reduce the temperature.

3. Therefore, when you want to open the heating valve, look at the valve from the front and rotate it in a counterclockwise direction to open the heating valve.

4. After opening the valve in this way, when the heating is not hot, you must check the room heater to open the valve and rotate it in a counterclockwise direction.

Generally, the number 0-5 is marked on the valve, 0 indicates the closed state, the number 1 is the smallest, and the number 5 is the largest; In addition, some valves are not marked with numbers, but with some graphics such as the sun and snowflakes, etc., the sun indicates the largest, and the snowflakes are closed; If nothing is marked, then turn the handwheel clockwise when opening the valve, turn the handwheel counterclockwise when closing, and rotate it in place according to the opening and closing indication mark, so that you can adjust the temperature of the radiator, which is very simple and convenient.

This type of valve is called a locking valve, and it is necessary to see if the valve is a magnetic locking valve or a normal locking valve. First take a picture of the valve to see what brand it is, and then look for the manufacturer of the valve on the Internet.

After determining the manufacturer, brand, and whether it is magnetic, buy a special key to open.

This valve is the locking valve on the heating pipe, you should open and close it for the property, this valve has special tools for the construction unit to hand over to the property after the construction is completed.

How to open the heating valve in the central heating community:

1.Open the valve of the house first, and then open the valve of the indoor pipe, many homes will set up the main valve, as long as you find the location of the main valve, you can find the location of the heating valve.

2.Then turn the water inlet valve counterclockwise, and put the handle of the valve and the pipe in a parallel state. 3.Then open the return valve in the same way, and then open the inlet and outlet valves of the water separator at the same time.

What is the heating valve:

1.The heating valve is divided into a globe valve (J), a gate valve (Z), a butterfly valve (D), a ball valve, and a check valve (H). When testing the water, open the inlet and return valves, and the running air should be closed.

2.The globe valve is used to cut off the flow of the medium, has a certain tempering performance, and the pressure loss is large, and is commonly used to cut off the flow of steam in the heating system. Temperature control valves or copper ball valves are generally used in front of radiators, globe valves are generally used on pipelines, locking control valves, filters, heat meters and balance valves are used at the entrance to the house, and there are globe valves, bypass valves, balance valves, discharge ball valves, pressure gauges, thermometers and heat meters at the heat inlet.

3.The gate valve is used to cut off the flow of the medium, when the valve is fully open, the medium can pass through as if it were a general pipe, without changing the flow direction, so the pressure loss is small. When the handle of the heating valve is a handwheel, turning to the left is closed, rotating to the right is open, if the valve is open, if the radiator is not hot, it is caused by the presence of air in the radiator pipe or radiator.

How to use the radiator temperature regulating valve:

1.There will be relevant markings on the heating temperature control valve, for example, there are 0 5 gears, and the indoor temperature is different when adjusted to different gears.

2.If you turn it on to Variable 5, the water flow in the heating pipe will be higher and the temperature will be higher.

3.If the temperature control valve is set to Variable 1, the water flow will be lower and the temperature will be lower.
