The valve is composed of valve body, valve cover, valve disc, rocker and other parts. The valve disc can automatically prevent fluid backflow. The valve disc of the valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet pressure is lower than the outlet pressure, the valve disc automatically closes under the action of fluid pressure difference, its own gravity and other factors to prevent the medium from flowing back.
