Q:Is it necessary to install a check valve in front of the water meter? Does the water company have a definite requirement?
UnnecessaryWater meter before the loss of running water, their own things, do not need customers to bearAfter the water meter is equipped with a small gate valve or a ball valve, it is convenient to repair and replace
Q:What is the function of the check valve on the air compressor?
It can cause damage to the compressor (usually called liquid hammer). Also, the exit may be frosted by returning air.
Q:What's the difference between the check valve and the stop valve?
Check valve is also called check valve or one-way valve, single-phase closed, individual hydraulic control one-way valve, plug valve also has a combination of controllable changes.The cut-off valve has the possibility of variable flow, two-way action, throttling possible, there can be two-way closed applications.
Q:What is the difference between the H44H check valve and the H41 check valve?
The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system2, attention should be paid to the direction of the flow of the medium should be in accordance with the direction of the body marked arrow3. Vertical lift check valves shall be mounted on vertical pipes4.
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 can the check valve at the flue port of the range hood be changed or cleaned?
If the flue hanging in the shed, it should be at the check out. Check valve with a machine.So I would not advocate the construction of flue hanging in the shed, net height kitchen, gas capacity is small this is big, the flue pipe exposed, there are many ways to deal with it.If the valve stuck inside, also find what professional people, find out what carpenter, solved the problem.
Q:How can the PPR pipe be connected to 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.
Q:Does the tap water return to the water?
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:Which side of the gate is the fire check valve in the pump room?
The check valve is installed between the shock absorbing flexible joint and the water outlet control valve at one side of the water outlet pipe of the water pump
Q:Detailed distinction between backflow preventer and check valve
The backflow preventer consists of two separated check valves and a drain valve. Due to the local head loss of the check valve, the pressure in the middle cavity is always lower than the pressure at the inlet. This pressure difference causes the drain valve to be closed and the pipe is in normal water supply. In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.Check valves are plain check valves, only one side seal. Backflow preventer is more expensive than ordinary check valve. Double protection and heavy protection!
