What's the use of stainless steel check valve, what are the characteristics

Stainless steel check valve is a kind of stainless steel as the material of check valve, check valve is to rely on the force created by the flow of the medium itself in the line of the automatic opening and closing of the valve, stainless steel check valve nature has all the features of the check valve, main effect is to prevent the backflow medium pipeline. Below is for the purpose and characteristics of stainless steel check valve to introduce as follows: stainless steel check valve can also be used to give the pressure could rise to more than the main system of auxiliary system supply piping. Check valve according to different materials, the pipeline can be applied to a variety of media. Check valve installed in the pipeline, that is, to become a full line of fluid components, one of the valve opening and closing process will be affected by it in system is influenced by transient flow state; On the other hand, the disc in closing feature and have hair effects on fluid flow state. Working characteristics of the stainless steel check valve is the load change is big, small open-close frequency, one in closed or open, apply cycle is very long, and does not require moving parts movement. But once again switch requirements, you must move it flexible, this is one of the more common mechanical movement is more demanding. 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 biggest flow back technology rapidly drop to zero, while the pressure rise rapidly, generating possible damage to pipeline system of water hammer. For more than one pump in parallel for high pressure pipeline system, the check valve water hammer problems become more prominent. Water hammer is one of the pressure transient flow in the pipeline pressure wave, which is caused by the change of the fluid velocity in pressure piping pressure jump or fall rise of the hydraulic impact phenomenon. Its physical reason is that the incompressibility of fluid, fluid motion inertia and elastic pipe combination results. In order to prevent water hammer in pipeline risk, over the years, people in the design of the check valve, adopted some new structure, new material, the guarantee of the check valve is applicable for the performance at the same time, minimize the impact of the water hammer has achieved gratifying progress. Check valve flow refers to rely on the media itself, and automatic opening and closing valve, used to prevent the backflow medium valve, also known as the non-return valve, check valve, valve, and the back pressure valve upstream.
