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: 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: The difference between the micro and slow closing check valve and the silent check valve: Micro slow closed silencing check valve hammer to drive the valve plate to open and close, silencing check valve spring pressure valve plate opening and closing, and the price of the body structure is completely different, but the function is the same, if the comparison between the two, large caliber selection micro slow closed check valve a little noise small caliber, the silencing check valve a little more.

Q: What's the use 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 are the differences between different check valves applications? For example, is the fire pump outlet swing check valve or a silent check valve? According to 35How to recognize single wall corrugated pipe and double wall corrugated pipe? Which is better?.What's the use of the silent check valve? And the bellow problem below, is there no answer?: General pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN<50mm.The pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valveSwing check valves can be installed horizontally or vertically.

Q: The difference between backflow preventer and check valve: 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.

Q: What can I do with the lift check valve?: With the structure of short length, small volume and light weight, the valve closed fast, water hammer pressure, flow smooth, fluid resistance small, horizontal or vertical pipe pipe can be used, easy installation, quick action, good sealing performance, the valve stroke is short, close the valve impact force is small, simple and compact, beautiful appearance, service life long, high reliability, to prevent the media back, the characteristics of automatic control. A lift check valve is used on an industrial pipe to prevent the flow of a medium.

Q: Ask questions about the installation of check valves after water meters: Generally installed after the water meter. The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter. A check valve is installed after the water meter, so that the situation can be avoided.

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: 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.
