Overview:

Lift check valve flow refers to rely on the media itself, and automatically open and close the disc, the valve is used to prevent the backflow medium, also called the non-return valve, check valve, flow valve, and the back pressure valve. Check valve belongs to a kind of automatic valve, its main role is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium.

function and characteristics

Lift check valve flow refers to rely on the media itself, and automatically open and close the disc, the valve is used to prevent the backflow medium, also called the non-return valve, check valve, flow valve, and the back pressure valve. Check valve belongs to a kind of automatic valve, its main role is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium. Check valve can also be used to give the pressure could rise to more than the system pressure of the secondary system supply piping. Main can be divided into swing check valve check valve (in accordance with the center of gravity rotating) and lift check valve (mobile) along the axis. Lift steel stop valves use: H41H lifting of steel, H41Y PN16 ~ PN100 stop valve is one of the important link of the production process control system, one-way flow of media is to control the pipe valve, to prevent backflow medium. Lift check valve features: 1, H41H, lifting of steel type H41Y stop valves has simple structure, reliable operation, convenient maintenance, are widely used in the purification equipment, petroleum, chemical, metallurgy, electric power, textile, etc. 2 in the process of production, the body indicated by the arrows to enter the body when the medium, the medium pressure produce upward thrust on the disc, when medium thrust is greater than the gravity disc, the valve opened.
