How much do you know about stainless steel check valves?Release Date: December 05, 2016
Stainless steel check valve is also known as backflow valve, check valve, back pressure valve, check valve. This type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belongs to an automatic valve. Stainless steel check valve is divided into lifting stainless steel check valve, swing-type stainless steel check valve, disc stainless steel check valve .
Stainless steel non-return valves can also be used to supply lines to auxiliary systems whose pressure may rise above the main system pressure. Stainless steel check valve can be applied to the pipeline of various media according to the different materials.
The check valve is installed on the pipeline, which becomes one of the fluid components of this complete pipeline. The flap opening and closing process is affected by the transient flow state of the system in which it is located. In turn, the closing characteristics of the flap Has an effect on the state of fluid flow.
The stainless steel check valve has a hinge mechanism, and a door-like valve disc is freely placed on the inclined seat surface. In order to ensure that the valve disc can reach the proper position on the valve seat surface each time, the valve disc is designed in a hinge mechanism, so that the valve disc has sufficient swing space, and the valve disc is in full contact with the valve seat. The valve disc of the lift check valve is located on the valve seat sealing surface on the valve body.
Except that the valve disc can be lifted and lowered freely, the rest is like a stainless steel check valve. The fluid pressure causes the valve disc to lift from the sealing surface of the valve seat. . Like shut-off valves, the passage of fluid through the stainless steel check valve is narrow, and the flow of the stainless steel check valve is less restricted.
