Usage/Applications Of Iron Check Valve：
Check valve is to rely on the flow of the media itself and automatically open, close the valve flap, used to prevent the media back valve, also known as the check valve, Dan Xiangfa, counter flow valve, and back pressure valve.
Check valve is an automatic valve, its main role is to prevent the media back, to prevent the pump and drive motor reversal, as well as the release of the container medium.

- Q: Can the check valve be used on the steam pipe?
- The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
- Q: What's the function of the small check valve on the deep well pump? Solve!When the deep well pump works, it does not move inside! Under great pressure！ There is a hissing sound when the deep well pump doesn't work! The air is in! Will it lead to the water in the room? There's a lot of air in it!
- Frequency conversion and it does not matter, the inverter is to speed down, so that the pump has a suitable flow and lift. This valve can not go.
- Q: Does the check valve differ in front of the water meter and press it behind the water meter?
- According to the specification, check valve (check valve) should be installed behind the watch. If it is placed in front of the meter, it will cause the meter to be inaccurate and damage the meter parts.
- Q: Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?
- Greater than DN600, you can use HBH747H hydraulic butterfly butterfly valve closed, less than DN600 with HD43X slow butterfly butterfly check valveThis is the usual selection, not necessary, there is no provision, but this choice is not wrong. There are, of course, other types of check valves.The hydraulic check valve is hydraulic, and the Baidu library contains instructions for the HB series and the HD series hydraulic check valves
- Q: What are the differences between the vertical check valve and the horizontal check valve in function and principle?.
- The vertical check valve and horizontal check valve are functionally and functionally indistinguishable.The difference between vertical check valve and horizontal check valve:Horizontal check valves, mounted in horizontal pipes, have the same shape as the globe valves; vertical check valves are attached to vertical pipes.Check valve is open and close parts, depending on the flow of medium and power to open or close, to prevent media backflow valve called check valve. The check valve belongs to the automatic valve, mainly used for one-way flow of medium pipe sleep, allowing only medium to flow in one direction, in order to prevent accidents.The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three.
- Q: Check valve and check valve
- Check valve, also known as check valve, are to prevent backflow of a medium valve
- Q: What does the swing check valve "h44h-16" mean?
- Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
- Q: Is it better to have explicit rules in the relevant specifications? Thank you, ah, ah, urgent.
- Article 8.5 of the code for fire protection design of high-rise civil buildings provides as follows:8.5.3 one of the following circumstances shall be equipped with fire dampers for the ventilation and air conditioning systems:8.5.3.1 pipe through fire compartment.
- Q: Check valves - check valves - what's the difference between one-way valves?
- Check valve. Check valve is the same, but the name is not the same. According to the customary name of the country. In fact, the same valve.
- Q: What does the check valve "H44Y-160" mean?
- Take a look at that JB/T 308 valve model compilation standards, which explain very clearlyH check valve, 4 flange connection, 4 spiral structure, Y is hard sealing hardfacing alloy. 160 is nominal pressure
