What are the various on off valves for heating?

There are five main types of heating valves, which are:Shut-off valves, safety valve, gate valve, check valve, butterfly valve, different types of valves, their use, use and other valves will be different, as follows:

1. Globe valve.

It is capable of cutting off the movement of the medium, has the corresponding regulation ability, and is usually used in heating systems to disconnect the movement of steam.

2. a safety valve.

It is mainly used for pressure relief when the medium pressure is too large, so as to protect the effect of equipment and systems, in some cases it can also be used as a system pressure valve after improvement, and this valve has many construction styles.

3. a gate valve. Its purpose is to disconnect the flow of the medium, when opening this valve, the medium can flow like a tube, and the direction will not change, so the pressure loss is not large, but its regulation performance is not good.

4. Check valve.

It allows the medium to move in one direction, and if the pressure behind the valve exceeds the pressure in front of the valve, then it will close by itself, and there are many styles of this valve.

5. Butterfly valve. It is set and switched by changing the angle of the valve disc, and it is normally in the middle of the flowing medium, so the resistance is very large, so it is not used much.

There are precautions to be taken when using a heating valve:

1. Turn on each radiator.

The gas release valve drains the gas inside, or opens the exhaust valve set up in the gas collection tank above the system to vent until each radiator becomes hot, then the debugging is completed, and after the debugging, the valve must be fixed and cannot be arbitrarily changed.

2. When starting the valve, it needs to be clockwise.

Turn the handwheel, as long as it turns counterclockwise when closing, and it needs to be turned to the marked location, the radiator can not change the position at will, nor can it release water arbitrarily, otherwise the water temperature in the pipe network will drop rapidly, thus affecting the indoor temperature.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

There are two types of heating valves, which are the valves that are pulled up and down, and the other is the valve that rotates the button, and the heating valve can be opened and closed according to the identification of the valve.

One. The valves on the heating pipes should not be opened and closed at will. If the heating system is running for the first time, it usually needs to be commissioned.

Here's how.

1. Adjust the position. Adjust the valves of each riser to the appropriate position.

2. Turn on each radiator.

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

3. When opening the valve, it should be 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.

4. If the valve is found to be faulty, it should be stopped immediately, the cause should be found out and the fault should be removed.

Direction of heating valve switch.

Twisting the heating valve to the left is closed, and twisting it to the right is open, so pay attention to the arrow indication sign of the heating valve. When testing the water, open the inlet and return valves. The running wind should be turned off.

Do not shake the heater and do not bear weight on the heating lines. Non-professionals should not dismantle the heating. The valve should not be opened and closed frequently during the heating season, and the valve should only be in a fully open or fully closed state. In the event of a water leak, close the inlet and return valves immediately.

Summary. From the front of the heating valve, you can see 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, it rotates counterclockwise 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.

Heating main valve switch.

Looking 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 an arrow in the direction of the counterclockwise wheel 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 according to the counterclockwise direction of Bigao.

Kiss. Which one is the heating valve.

Red pro. It's all red.

Yes dear.

The various on/off valves for heating are as follows:

1. Globe valve: used to cut off the flow of medium, has a certain tempering performance, large pressure loss, and is commonly used to cut off the flow of steam in the heating system, and is used in the valve model"j"Indicates a globe valve.

2. Safety valve: It is mainly used for pressure relief when the medium is overpressurized to protect the equipment and system. 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.

3. Gate valve: used to cut off the flow of medium, when the valve is fully opened, the medium can pass through the general pipe without changing the flow direction, so the pressure loss is small. The regulation performance of the gate valve is very poor, and it is used in the valve model"z"Indicates a gate valve.

4. Check valve: also known as check valve or check valve, it allows the medium to flow in one direction, if the pressure behind the valve is higher than the pressure before the valve, the check valve will be automatically closed. There are many types of check valves, mainly including:

Lifting, swinging, 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.

5. Butterfly valve: by changing the angle of the valve disc to achieve adjustment and switching, because the valve disc is always in the middle of the flowing medium, the resistance formed is larger, so it is rarely used. Used in valve models"d"Denote.

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, open the inlet and outlet valves of the water separator at the same time. 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, open the windproof valve of the water separator or radiator and 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 about 18 degrees Celsius, so that it will not consume too much energy and 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.

The on/off valves of heating include globe valves, safety valves, gate valves, check valves, butterfly valves, etc. Shut-off valve: It can cut off the movement of the medium, has the corresponding adjustment ability, and is usually used in the heating system to disconnect the movement of steam.

Safety valve: It is mainly used for pressure relief when the medium pressure is too large, so as to protect the equipment and system, and can be used as a system constant pressure valve after improvement. Gate Valve:

Its purpose is to disconnect the flow of the medium, and when the valve is opened, the medium flows smoothly without changing direction and with low pressure loss. <

1. Globe valve: It can cut off the movement of the medium, and has the corresponding adjustment ability, and is usually used in the heating system to disconnect the movement of steam.

2. Safety valve: It is mainly used for pressure relief when the pressure of the medium slag ridge is too large, so as to protect the equipment and system if it seeps, and can be used as a system constant pressure valve after improvement.

3. Gate valve: its purpose is to disconnect the flow of the medium, when opening this valve, the medium can flow smoothly, and the direction will not change, and the pressure loss is also small.

4. Check valve: it can make the medium move in one direction, if the pressure behind the valve exceeds the pressure in front of the valve, then it will close by itself.

5. Butterfly valve: It is set and switched by changing the angle of the valve disc, and it is normally in the middle of the flowing medium, so the resistance is large.

The various on-off valves for heating are: safety valves, which are divided into hammer lever type, spring micro opening type and pulse type, check valve, globe valve and gate valve, butterfly valve to adjust the flow rate and so on. The valve is a pipeline attachment used to open and close the pipeline, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveyed medium.

If you have children at home or are preparing to have children, you must have heating, and the benefits of heating for children should be seen before the warm cube.

Winters in the south are always wet and cold, and if you have heating in your home, it's like adding a powerful free dryer to your home.

If there is a busy person at home, don't worry about waiting for him to come back to eat the meal will be cold, and don't bother to go to him every time to give him a hot meal, if you have heating at home, put the meal directly on the heater, you can keep the meal warm.
