The design characters of wafer type duo check valve
Check valve is used for preventing the back flow of medium in pipelines and equipments. It will open and close automatically by the pressure of medium. When the medium is back-going, valve disc will close automatically to avoid accidents.
1. Tightly sealed, without leakage under the water pressure testing.
2. Economical, light weight, compact design-significantly lighter and less expensive than comparable swing check valves.
3. Easy to install and maintain.

Q:An introduction to the check valve
The check valve, also known as reverse flow valve, check valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force produced by the flow of the medium of the pipeline itself. It belongs to an automatic valve.
Q:Does the check valve differ in front of the water meter and press it behind the water meter?
Check valve is mainly to prevent water backflow, backflow, easily lead to water damage
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. Pump water off the bottom valve check valve also belongs to class. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.
Q:The self-priming pump with check valve (check valve, water valve)?
Self suction pump reverse water valve is a 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.
Q:Can the flue check valve and kitchen check valve protect against odor?
Not really. It depends on what valve it is. If it is a variable pressure air valve, of course, if it is an ordinary other valves, generally only temporary role. Five residential home kitchen platoon smoke system is the application of this variable pressure air valve.
Q:Check valve and check valve
Check valve in English check valve, also known as check valve, the English non-return valve is the same valve different name
Q:What are the differences between the vertical check valve and the horizontal check valve in function and principle?.
The check valve has a baffle inside it, usually closed by gravity,The function and working principle are basically indistinguishable
Q:What is the reason that the check valve does not stop water?
7, when installing check valve, should pay special attention to medium flow direction, should make medium normal flow direction and the direction of the arrow on the valve body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.The general formula 8, lift check valve should be installed in horizontal pipe, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.9, the check valve closes, will produce water hammer in pipeline pressure, will lead to serious damage to the valve and piping or equipment, especially for the big pipe or high pressure pipeline, it should pay attention to those who use check valve.
Q:Does the check valve damage affect the flow rate?
Ball check valve will not affect the flow, such as the clip type check valve once damaged, it will affect the flow.
Q:Why can't parallel check valve be installed firmly?Anonymous browsing | 51 times
The vertical installation is easy to cause the valve core of the check valve to clamp off or fall off, and lose the function of checking back. The direction of the check valve is restricted seriously from any direction of the medium
