The relationship between sanitary check valve and sanitary quick-install check valve

The relationship between the sanitary check valve and the sanitary quick-fit check valve The flange check valve and the stop valve are not the same thing, the difference between the two is mainly that the structure is very different. The check valve is a one-way valve, which automatically prevents the fluid from flowing in the reverse direction, without a knob, and cannot artificially block the forward flow. The shut-off valve has a knob and can artificially control the forward flow. Due to its special structure, even if there is no artificial pipe valve, the fluid cannot flow in the reverse direction. Check valve is also called reverse valve, check valve, back pressure valve, one-way valve. This kind 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. The function of this type of valve is to only allow the medium to flow in one direction, and to prevent the flow of the direction. Usually this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve flap act on the valve seat, thereby cutting off the flow. Its main function is to prevent the medium from flowing backward, to prevent the pump and drive motor from reversing, and to discharge the container medium. According to the structure, it can be divided into four types: floating, fixed, elastic and oil-sealed; according to the channel, it can be divided into: direct energy, angle and three-way, etc. The three-way can be divided into T There are two types: L-shaped and L-shaped; according to the connection mode, it can be divided into three types: threaded connection, flange connection and welding type. The same thing, different names, the appraisal is complete. There are many price differences, which may be caused by differences in specifications, materials, performance, etc. Check valve (also known as check valve) refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent the medium from flowing back, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is a kind of automatic valve, its main function is to prevent the back flow of the medium, prevent the pump and the drive motor from reversing, and the discharge of the container medium. Check valves can also be used to supply pipelines for auxiliary systems where the pressure may rise above the system pressure.
