The Relationship Between Sanitary Check Valve And Sanitary Quick-install Check Valve
The relationship between sanitary check valve and Sanitary Check Valve
Flange check valve and stop valve are not the same thing. The difference between the two is that the structure is very different. Check valve is a one-way valve that automatically prevents the reverse flow of fluid. It has no knob and cannot artificially block the forward flow.
Stop valve has a knob and can artificially control the forward flow. Due to its special structure, the fluid cannot flow in the reverse direction even without an artificial pipe valve. Check valve is also called reverse flow valve, non-return valve, back pressure valve, one-way 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 is an automatic valve.
The function of this type of valve is to allow the medium to flow in one direction only and prevent the flow in the opposite direction. Usually this valve works automatically. Under the pressure of the fluid flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the self-recognition valve disc of the fluid pressure and the valve disc acts on the valve seat, thereby cutting off the flow. Its main function is to prevent the backflow of the medium, the reversal of the pump and the drive motor, and the discharge of the container medium. According to the structural form, it can be divided into four types of check valves: floating type, fixed type, elastic type and oil-sealed type; according to the channel, it can be divided into: direct energy type, angle type and three-way type, etc.,
The three-way type can be divided into two types: T-shaped and L-shaped; according to the connection method, it can be divided into three types: threaded connection, flange connection and welding. The same thing, different names, identification is complete. The price difference may be caused by differences in specifications, materials, performance, etc. A check valve (also known as a check valve) refers to a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent the backflow of the medium. It is also called a check valve, a one-way valve, a reverse flow valve, and a back pressure valve. The check valve is an automatic valve, and its main function is to prevent the backflow of the medium, prevent the pump and the drive motor from reversing, and the discharge of the container medium. The check valve can also be used on the pipeline to provide supply to the auxiliary system where the pressure may rise to exceed the system pressure.
