New bell jar valve Aluminum factory Pneumatic valve Bell jar emptying valve Special bell jar for aluminum factory

Bell jar valve is a special valve for pressure tank of alumina powder dilute and dense phase conveying pipeline system in electrolytic aluminum plant. Pneumatic device is used to operate the valve to open and close, equipped with valve closed position signal feedback switch, which can realize remote operation and automatic control of system working program. Solenoid valve has dust function, especially suitable for use in dusty environment.

Xinhai environmental protection bell valve features:

It has compact structure, small occupied area, strict air tightness and high reliability, especially in the driving device, which has been greatly improved from fixed opening and closing to synchronous opening and closing. An operator is added to ensure that the opening and closing of the valve disc always keeps vertical movement with the axis line, thereby improving the service life of the lifting rope and reducing faults. The operation of the valve disc is designed with a guide system to make it run smoothly, corrosion resistance, wear resistance and pressure resistance nickel base alloy as a sealing pair, and line sealing is adopted to eliminate the influence of medium on sealing performance and improve the reliability and pressure resistance of sealing.
