The stainless steel check valve is actually a stainless steel check valve. The check valve is an automatic valve that automatically opens and closes by the force generated by the flow of the medium in the pipeline. The stainless steel check valve naturally has a check valve. All product characteristics of the valve, the main role is to prevent the pipeline in the media backflow. The following describes the use and characteristics of stainless steel check valves as follows:

Stainless steel check valves can also be used on pipelines where the pressure may rise above the main system pressure of the auxiliary system. The check valve can be applied to the piping of various media depending on the material. The check valve is installed in the pipeline, which is one of the fluid components of this complete pipeline. The valve opening and closing process is affected by the transient flow state of the system in which it is located; in turn, the closing property of the valve is It has an effect on the fluid flow state.

The stainless steel check valve is characterized by a large load change, a small opening and closing frequency, a closed or open state, a long application cycle, and no movement of the moving parts. However, once the “switching” requirements are met, they must be flexible and flexible. This requirement is more demanding than common mechanical movements. Since the check valve is qualitatively determined to be used for quick closing in most practical applications, the medium is flowing in the direction of the moment when the check valve is closed. With the closing of the valve, the medium rapidly drops from the maximum reverse speed to Zero, but the pressure is rapidly rising, that is, the phenomenon of "water hammer" that may have a destructive effect on the pipeline system. For high pressure piping systems with multiple pumps connected in parallel, the water hammer problem of the check valve is more pronounced. Water hammer is a kind of pressure wave in the transient flow in the pressure pipeline. It is a hydraulic impact phenomenon that the pressure rises or falls due to the change of the fluid velocity in the pressure pipeline. The physical reasons for this are the combined effects of the incompressibility of the fluid, the fluid motion inertia, and the duct elasticity. In order to prevent the water hammer in the pipeline from being hidden, over the years, people have adopted some new structures and materials in the design of the check valve. While ensuring the applicable performance of the check valve, the impact of the water hammer is minimized. Have made gratifying progress. The check valve is a valve that automatically opens and closes the valve flap, and is used to prevent the back flow of the medium depending on the flow of the medium itself. It is also called a check valve, a one-way valve, a backflow valve, and a back pressure valve.
