ANSI 150LB Stainless steel wafer check valve

Stainless steel wafer check valveis also known as reverse flow valve, check valve, back pressure valve, one-way valve.This kind of valve depends on the flow of the medium itself in the pipeline and automatically open and close the force, belongs to a kind of automatic valve.Check valves are used in piping systems to prevent backflow of media, to prevent the reversal of pumps and their driving motors, and to prevent the release of media in containers.Check valves can also be used in piping where pressure may rise above the primary system pressure to supply the secondary system.

Check valves can be used on all kinds of media depending on the material.Check valve installed in the pipeline, that is, become one of the complete pipeline fluid components, the disc opening and closing process will be affected by the transient flow state of the system where it is;In turn, the disc's closing behavior has an effect on the flow state.Check valve is characterized by large load variation, small opening and closing frequency, a put into closed or open state, the applicable cycle is very long, and does not require the movement of parts.But once the "switch" requirements, must be flexible, this requirement is more demanding than the common mechanical movement.Due to the check valve in the most practical use, qualitatively determine for fast shut down, and at the instant of the check valve is closed, the medium is a direction, with the disc in closing, the medium from the rapid rate of maximum back down to zero, while the pressure rise rapidly, generating possible damage to pipeline system of "water hammer" phenomenon.For high pressure pipeline system with multiple pumps in parallel, the water hammer problem of check valve is more prominent.Water hammer is a kind of pressure wave in the transient flow in the pressure pipe. It is the hydraulic impact phenomenon of pressure jump or drop caused by the change of fluid velocity in the pressure pipe.The physical reason is the result of the combined action of fluid incompressibility fluid motion inertia and pipe elasticity.In order to prevent the hidden trouble of water hammer in pipeline, over the years, people have adopted some new structures and materials in the design of check valve, which has made gratifying progress in minimizing the impact force of water hammer while ensuring the applicable performance of check valve.Check valve is to rely on the flow of the medium itself and automatically open, close the disc, used to prevent media backflow valve, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.Check valve belongs to a kind of automatic valve, its main function is to prevent the backflow of media, prevent the reversal of pump and drive motor, as well as the release of container media.Check valves can also be used in piping where pressure may rise above system pressure to supply an auxiliary system.Check valves can be divided into swing check valves (rotating according to the center of gravity) and lifting check valves (moving along the axis).
