Description of the structural characteristics of the ball type check valve

Ball check valves, also known as check valves, are designed to prevent backflow of media in the line. The valve of the opening and closing member is opened or closed by the flow of the medium and the force to prevent the back flow of the medium from being called a check valve. Check valves are automatic valves, mainly used on pipes with one-way flow of media, allowing only the media to flow in one direction to prevent accidents.
1. The structure length is short, and its structure length is only 1/4~1/8 of the traditional flange check valve;
2, small size, light weight, its weight is only 1/4 ~ 1 / 20 of the traditional micro-resistance slow-closing check valve;
3, the valve flap is closed quickly, the water hammer pressure is small;
4, horizontal or vertical pipeline can be used, easy to install;
5, the flow path is smooth, the fluid resistance is small;
6, the action is sensitive, the sealing performance is good;
7. The valve stroke is short and the impact force of the valve is small;
8, the overall structure, simple and compact, beautiful appearance;
9. Long service life and high reliability.
