Sealing ball valve suitable for gas conveying pipeline

Abstract

The invention discloses a sealing ball valve suitable for a gas conveying pipeline, and belongs to the field of ball valves. According to the scheme, when gas is conveyed in a valve body, the gas can be guided out through a ball valve assembly, and when the gas enters the ball valve assembly, the gas can be guided into a connecting cylinder through a vent hole, so that the gas conveying efficiency is improved; meanwhile, when the temperature of the gas is high, heat can be absorbed through the heat conduction filler between the vent holes, heat is guided into the cooling balls for cooling, so that the high temperature of the gas is not prone to influencing components in the connecting cylinder, after the gas enters the connecting cylinder, the gas drives the adsorption balls to shake between the elastic films, and the adsorption balls are prevented from shaking; according to the air purifier, the air enters the adsorption balls, the air is filtered and purified through the purification liquid in the permeable membrane, the exhausted air is purified to the maximum extent, primary filtration is conducted through the outside of the elastic membrane when the air enters and is exhausted, and then the filtration and purification effect of the purification liquid is achieved.

Description

technical field [0001] The invention relates to the field of ball valves, and more particularly, to a sealed ball valve suitable for gas conveying pipelines. Background technique [0002] Ball valve, the opening and closing part (sphere) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. There is a strong shearing force between the metal valve seats, which is especially suitable for media containing fibers, tiny solid particles, etc., and the multi-port ball valve can not only flexibly control the confluence, shunt, and flow direction switching of the medium on the pipeline, but also It is also possible to close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. The ball valve is divided into: pneumatic ball valve, electric ball valve, and manual ball valve according to the driving method. [0003] In the prior art, the ba...

Problems solved by technology

[0003] In the prior art, the ball valve is generally used to cut off, distribute and change the flow direction of the medium, but in the pipeline of gas transportation, some content in the gas may be relatively large, which will cause the gas to be purified by external purification after the gas is output. equipment to filter, but it is more complex and costly
