What is the role of metal bellows in bellows valves？
The bellows valve is a common type of valve that works by using the elastic deformation of the bellows to control the flow of fluid. Bellows valve is usually composed of bellows, valve body, valve cover spool and other components, of which bellows is the key component.
Corrugated pipe is an elastic metal pipe, it can be elastic deformation under the action of pressure or tension. Bellows valves take advantage of this characteristic of bellows to control the flow of fluid. When the bellows are subjected to pressure, it will undergo elastic deformation, which causes the spool to move, thereby controlling the flow of fluid. When the bellows are not under pressure, it will return to its original state, so that the spool is returned to its original position and the valve is closed.
The advantages of the bellows valve are simple structure, high reliability, good sealing, long service life, etc. It is suitable for various media, including liquid, gas, steam and so on. The disadvantages of the bellows valve are small flow, large pressure loss, slow switching speed and so on. Therefore, it is usually used in low-flow, low-pressure occasions
Bellows valves have a wide range of applications, including chemical, oil, gas, pharmaceutical, food and other industries. In the chemical industry, bellows valves are usually used to control the flow of corrosive media in the oil and gas industry, bellows valves are usually used to control the flow of high temperature and high pressure media: in the pharmaceutical and food industries, bellows valves are usually used to control the flow of hygienic grade media.
