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: Automatic water tower water reflux, plus a check valve not supposed: Check the direction of the installation is correct, check valve quality is good, you can install two 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 is the difference between the silent check valve and the silent check valve?: DRVZ according to the outline of the design of hydraulics has streamlined waterway better, with the design of internal guide fluid to ensure minimal pressure loss, silent check valve in water backflow before quickly shut down to avoid water hammer, water hammer sound and destructive impact to mute.

Q: The difference between the micro and slow closing check valve and the silent check valve: Noise check valve is to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, noise check valve, reverse 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).

Q: 40 how large check valves are installed in the water pipes?: Crown valve press40 of the pipe outer diameter of 48 DN40 check valve on it

Q: What is the function of the stop valve and check valve installed on the water supply pipe?: globe valves for a wide range of pressure and temperature, but are generally used for medium and small diameter pipes. The home tap water valve should be designed as most of the 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: Are the gate valves and check valves of the same type?: Not the same gate valve, it is a kind of opening and closing function (i.e. switch) of the valve, it is on the gate lifting and play the role of the switch, the switch is to be applied by external force (hand wheel, electric, pneumatic and hydraulic) it is not required to;

Q: Is the tank stop valve a non-return valve or a check valve?: The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.

Q: I use water pump pumping 78 meters deep underground water, the pipe is 2.5 inches large, with ordinary check valve, water is always sucked back, I would like to ask what method or what kind of check valve to be selected (check valve to be installed on the side of the pump): 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: How does the check valve work?: In order to ensure that the valve can reach the appropriate position of the seat surface at any time, the disc is designed in the hinge mechanism so that the disc has enough swing space to make the disc real and comprehensive contact with the valve seat. The disc can be made of either metal or leather, rubber, or synthetic coverage, depending on performance requirements. The swing check valve is almost completely open and the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively small. The check valve of the lift check valve is located on the valve seat sealing surface of the valve body. In addition to this valve disc is free to lift, like the rest of the cut-off valve, the fluid pressure valve from the valve seat sealing surface lift, medium return led down to the valve seat, and cut off the flow. Depending on the service conditions, the disc can be of all metal construction or in the form of a rubber pad or rubber ring on the valve frame. The same as the cut-off valve, lift check valve fluid through the channel is narrow, so the check valve by lifting the pressure drop than the swing check valve a little bigger, and swing check valve flow restrictions very little,
