For home use, self suction pumps are installed outside the well and pumped into the water tank.Please check with the self-priming pump function (check valve, water valve)? If not, is not installed in the pipeline connecting wells and pumps? Thank you。
Water inlet generally has a check valve, if not, then only in the suction port on the installation of the check valve. Of course, you can also install a one-way valve on the pipe near the suction port.
If there is no sealing self-priming pump, no check valve is required
Both, but there are good or bad points, good seal, with a spring, the general is a piece of rubber plus a piece of iron, plus a check valve is feasible
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.
