Cast Iron Flange Check Valve For Horizontal And Vertical Pipes,GB Standard

Usage:

The purpose of this valve is to prevent the medium on all kinds of pipelines or equipment from countercurrent, and it is used for one-way opening and closing

Action principle

1. This valve is a flange connected iron swing check valve in accordance with gb/t 13932 standard.

2. This valve is composed of valve body, valve cover, valve disc, rocker and rocker shaft and other parts. This valve can automatically prevent fluid backflow. The valve disc of this 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 medium backflow.
