Product description
summary:
The check valve is installed in the pipeline system, and its main function is to prevent the backflow of medium. The check valve is an automatic valve that depends on the pressure of medium to open and close. In the past, h44 flange connected swing check valve and H41 flange connected lift check valve were widely used in China. This traditional check valve has bulky volume, large fluid resistance, high water hammer pressure when the valve is closed, difficult installation and maintenance, and short service life.
In view of the problems existing in the traditional structure check valve, based on the American API standard and the German DIN standard, and combined with our rich experience in valve test research, development and design, processing and manufacturing for many years, our company has developed h76 wafer double disc swing check valve and H71 wafer lift check valve series products, which have been tested in petrochemical, metallurgy, electric power, light industry Enterprises and equipment supporting manufacturers in food and other industries have used it for many years, and the effect is good, which is well received by users.
Structural features:
1. The structural length is short, and its structural length is only 1/4 ~ 1/8 of the traditional flange check valve;
2. Small size and light weight, its weight is only 1/4 ~ 1/20 of the traditional flange check valve;
3. The valve disc closes quickly and the water hammer pressure is small;
4. Horizontal pipe or vertical pipe can be used, easy to install;
5. The flow passage is unobstructed and the fluid resistance is small;
6. Sensitive action and good sealing performance;
7. The stroke of valve clack is short, and the impact of valve closing is small;
8. The overall structure is simple, compact and beautiful;
9. Long service life and high reliability.
