Structure principle of Dual plate wafer Non-return check valve

2022-09-01 13:13

Dual plate wafer Non-return check valve is used in pure pipelines and industrial, environmental protection, water treatment, high-rise building water supply and drainage pipelines to prevent reverse flow of media. The check valve adopts a wafer type, the disc is two semicircles, and the spring is forced to reset. The sealing surface can be surfacing wear-resistant material or rubber lining, which has a wide range of use and reliable sealing.

Dual plate wafer Non-return check valve opening and closing parts are automatically opened or closed by the medium flow and force to prevent the backflow of the medium. The valve is called a check valve. The check valve belongs to the automatic valve category, which is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.
According to the structure, check valves can be divided into three types: lift check valves, swing check valves and butterfly check valves. Lift check valve can be divided into vertical and horizontal. The swing check valve is divided into three types: single-lobe, double-lobe and multi-lobe. The manufacturer of Dual plate wafer Non-return check valve tells you that the butterfly check valve is a straight-through type, and the connection forms of the above check valves can be divided into three types: threaded connection, flange connection and welding. A check valve is a valve that automatically prevents the backflow of fluid. The disc of the check valve opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. The manufacturer of Dual plate wafer Non-return check valve tells you that when the pressure on the inlet side is lower than that on the outlet side, the valve disc will automatically close under the action of fluid pressure difference, gravity and other factors to prevent the fluid from flowing back.
