Technical Field

[0001] The utility model relates to the field of bellows valves, in particular to a high-purity bellows valve. Background Art

[0002] The bellows valve is a pressure-balanced regulating valve with a compact valve body structure, an S-shaped streamlined fluid channel, small pressure drop loss, large flow rate and a wide adjustable range. The high-purity bellows valve is a key component in the high-tech field and is mainly used in high-pressure, high-temperature and ultra-high-purity environments. It has excellent sealing performance. Since the bellows has good elastic deformation ability, it can ensure the sealing performance of the valve. The existing bellows valve is difficult to control when it is used due to the influence of pressure and impact force, making the valve opening and closing difficult, making the valve structure easy to be damaged, and reducing the overall stable use effect; so we proposed a high-purity bellows valve to solve the above problems.
