Q:Check valve h42h-dn80 what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve4 = connection: flange2 = structure form: vertical lifting typeH = sealing surface material: Cr13 stainless steelDN80== nominal diameter: 80mm
Q:The principle of the check valve
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:What kind of check valve is used to prevent the return water?
The problem can't be solved: if you change the pipe, you'll have a vertical check valve
Q:What is the air pipe check valve?
One-way valve, one-way flow, to prevent negative pressure reflux.
Q:What are the differences between the vertical check valve and the horizontal check valve?
The main difference is whether the valve center and valve seat are placed horizontally or vertically. It is usually designed with the pipe
Q:What is the reason that the check valve does not stop water?
4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.
Q:Which kind of steam check valve is good?
Steam check valve selection spring pressure check valve is better, can be sealed tight.Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline.

Q:Check valve selection
1, do not use ordinary ball check valve, rubber check valve, quick response, but it is not very durable2, vacuum tank3, I think the most benevolent is, get an auxiliary start pump, small kind of, the head is not too high, connect the municipal pipe network, open the main pump before the auxiliary pump irrigation. But the premise is that your main pump is a centrifugal pump
Q:What is the difference between check and check valves? Check and check valves?
2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.
