- Q:Are the gate valves and check valves of the same type?
- Check valve is a check valve function, is to prevent the media back, it is by the valve on the pin shaft and the rotary switch to play the role of the valve with different things, when it is opened by medium pressure automatic opening, closing time depending on the medium and back type the self gravity valve closed, it is a kind of automatic gate valve function, does not require an external force is applied to it, it is a demand for the direction.
- Q:What does the H/F/P stand for in the check valve H41H/H41F/H41P?
- Respectively, the valve seat sealing surface is made of alloy / fluorine plastic / stainless steel.
- Q:What happens when the check valve is broken?
- Check valve is broken, there will be back water, down pressure, serious will produce pump reversal, burning motor
- Q:Use of fire pump adapter even before you install a check valve
- Multifunctional pump combination device usually comes with safety valves and check valves, usually in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.
- Q:Is the hdf41x 1.6Mpa a check valve?

- Q:Can the slow stop disc check valve close quickly?
- At the same time, the pressure of the inlet medium into the lower part of the piston in the oil cylinder to push the piston, the small end of the upper part of the oil cylinder piston through the needle valve are respectively pressed into both sides of the valve body, the piston rod extends out of the small cylinder. When the pressure of the inlet medium drops below the outlet pressure, the medium will produce a return flow.
- Q:Swing check valve can prevent any sewer defection
- 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. This kind of valve should be installed horizontally in the pipeline.
- Q:How to install the check valve?
- Three disc check valve: disc check valve around the pin rotation in the valve seat. The disc type check valve is simple in structure and can only be installed on the horizontal pipe. The sealing performance is poor.Four. Check valves: Valves sliding along the centerline of the valve. Pipe type check valve is a new kind of valve. It is of small size, light weight and good processing technology. It is one of the developing directions of check valve. But the coefficient of fluid resistance is slightly larger than that of the swing check valve.Five, compression type check valve: This valve is used as boiler water supply and steam cutting valve, it has lift check valve and stop valve or angle valve comprehensive function.In addition, there are - some do not apply to pump outlet check valve is installed, such as valve, spring type, Y type check valveNote: check valve installation should pay attention to the direction of the anti installed, there is no effect.
