During the use of this valve, the medium flows in the arrow direction shown in the figure.
1. When the medium flows in the specified direction, the valve clack is opened under the action of medium force; When the medium is countercurrent, due to the dead weight of the valve clack and the effect of the reverse force of the medium, the valve clack and the sealing surface of the valve seat are closed to prevent the medium from countercurrent.
2. The sealing surface of the valve body and valve clack shall be welded with stainless steel.
3. The structural length of this valve shall comply with GB12221-1989, and the flange connection size shall comply with JB/T79-1994.
Low temperature check valve refers to the valve that automatically opens and closes the valve clack depending on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, backflow valve and back pressure valve. The check valve belongs to an automatic valve, which is mainly used to prevent the backflow of medium, prevent the reverse rotation of pump and drive motor, and discharge the container medium. The check valve can also be used to feed the auxiliary system whose pressure may rise above the system pressure. The check valve can be divided into swing check valve (rotating according to the center of gravity) and lift check valve (moving along the axis).
