Radiator valves are the most common type of radiator system. Heating is often used in the north in winter. The direction of the heating valve has a certain influence on the heating. The direction of the heating valve is reasonable. What about the types of heating valves? It may be a topic that everyone cares about. The following is a small series to introduce you!
First, the common radiator valve:
1. The safety valve is mainly used for pressure relief when the medium is overpressured to protect equipment and systems. In some cases, the micro-open hydraulic safety valve has been modified to be used as a system pressure regulator. There are many structural forms of the safety valve, which are indicated by "Y" in the valve model.
2. Common radiator valve: The check valve is also called check valve or check valve, which allows the medium to flow in one direction. If the pressure behind the valve is higher than the pressure in front of the valve, the check valve will automatically close. There are many types of check valves, including: lift type, swing type and so on. The lifting type valve external body stop valve has large pressure loss, so it is less used in the new heat exchange station system. It is indicated by "H" in the valve model.
3. Common radiator valve: The stop valve is used to cut off the medium flow, has certain regulation performance, and has large pressure loss. It is commonly used in the heating system to cut off the flow of steam. In the valve model, "J" is used to indicate the stop valve.
4. Common radiator valve: The gate valve is used to cut off the flow of the medium. When the valve is fully open, the medium can pass like a normal pipe without changing the flow direction, so the pressure loss is small. The adjustment performance of the gate valve is very poor. In the valve model, the "Z" is used to indicate the gate valve.
5. Common radiator valve: The butterfly valve realizes adjustment and switching by changing the angle of the valve disc. Since the valve flap is always in the middle of the flowing medium, the resistance formed is relatively large, so it is also less used. It is indicated by "D" in the valve model.
Second, the switch direction of the radiator valve
The heating temperature regulating valves are generally spherical valves. The valves are generally adjusted before leaving the factory. They should only be in two directions. When the handle is moved along the pipe, it is turned on and rotated 90 degrees to close. If some of the radiators are not hot, most of the problems are caused by air damping in the heating chamber, and how to open the heating switch.
The heating valve is a kind of valve with a hand wheel. The use of this valve is that the left twist is closed half closed, the right twist is to open the valve, the general valve has a sign, there is an arrow pointing, you can press the arrow on time The direction is open and the heating quality is heavy. The technical content of the heating is relatively high, the use time is long, and the problem is easy to cause joint loss. Therefore, the installation quality and after-sales service are the second life of the heating. After you have selected high-quality, beautiful and comfortable heating, you must not neglect the important part of installation. The selection principle of heating installation is: professional, skilled and guaranteed.
When testing the water, keep a person in the house and open the inlet and return valve. The running wind should be off. Do not shake the heater, do not load the heating pipe.
Non-professionals should not dismantle the heating Valves should not be switched frequently during the heating season, and the valves can only be fully open or fully closed. When there is a leak, immediately close the inlet and return valves.
This Screen Rolling Tool is constructed from PP. It features convex and concave rollers with a plastic handle. This tool is used to install fiberglass screen fabric and vinyl spline into Window Screen frame. Spark surface design make the holding more easy, which enhance your operation to seal the spline.
As the professional Insect Screen supplier, we would like to cooperated with consumer from all the world to develop more tool, to make sure the Screen Window/door installing become more easy.
