API 594 Dual plate check valve is used for pure pipelines and industrial, environmental protection, water treatment, water supply and drainage pipelines in high-rise buildings to prevent the reverse flow of media. The check valve adopts a wafer type, the butterfly plate is two semicircles, and adopts a spring to force the reset, the sealing surface can be the body surfacing welding wear-resistant material or rubber lining, the use range is wide, and the sealing is reliable.
The opening and closing parts of API 594 check valve rely on the flow and force of the medium to open or close by themselves to prevent the medium from flowing back. The valve is called the check valve. Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents.
According to the structure of the check valve, it can be divided into three types: lift check valve, swing check valve and wafer check valve. Lift check valves can be divided into two types: vertical and horizontal. Swing check valves are divided into three types: single valve, double valve and multi valve. The wafer check valve is a straight-through type. A check valve is a valve that can automatically prevent fluid from flowing back. The valve flap of the check valve opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve flap is automatically closed under the action of the fluid pressure difference, gravity and other factors to prevent the fluid from flowing back.
