Abstract

The invention discloses a correctable automatic adjustment double-plug linkage liquid leakage prevention exhaust valve. The valve comprises a valve body, an upper-stage cavity and a lower-stage cavityare formed in the valve body, a piston pipe is installed at the upper end of the valve body in a sealed and threaded mode, and the lower end of the piston pipe extends into the upper-stage cavity andis provided with a synchronous pipe in a sealed and sliding insertion mode. The synchronous pipe sleeves a sealing plug, and the lower end of the synchronous pipe extends into the lower-stage cavityand is provided with a floating ball plug. Linkage sealing is achieved through the sealing plug and the floating ball plug under the action of the synchronous pipe, the liquid leakage degree is sensedthrough a pressure regulating floating ball, and a pressure regulating air hole is opened through a piston column to release high-pressure gases in the floating ball plug into the upper-stage cavityto restrain rising of the liquid level and increase buoyancy of the floating ball plug. Reinflation correction reuse is achieved through the piston pipe and a one-way inflation nozzle, the service life of the exhaust valve is prolonged, the liquid leakage prevention effect is improved, the liquid conveying cost is saved, and resource waste is avoided.

Description

technical field [0001] The invention relates to the field of exhaust valves, in particular to a correctable and automatically adjustable double-plug linkage anti-leakage liquid exhaust valve. Background technique [0002] During the pipeline transportation, the inclusion and dissolved gas in the liquid will be precipitated, and the bubbles will be generated to increase the transportation resistance and increase the kinetic energy loss during the transportation process. Therefore, it is necessary to discharge the gas in the pipeline to improve the transportation efficiency. [0003] Existing exhaust valves are usually floating exhaust valves. A floating ball rises with the buoyancy of the liquid to close the valve port, and the air accumulates to generate air pressure to make the liquid level drop, so that the floating ball descends to open the valve port to discharge the air, while the liquid The pressure causes the floating ball to float up again to block the valve port to ...
