High-pressure gas-controlled bacteria valve

Abstract

The invention relates to the technical field of valves, in particular to a high-pressure gas-controlled bacteria valve. The high-pressure gas-controlled bacteria valve comprises a first shell, a valveelement, a second shell and a pneumatic part; a medium cavity is formed inside the first shell, an inlet channel communicating with the medium cavity and the outside is formed in the first shell, andan outflow channel communicating with the medium cavity and the outside is further arranged on the first shell; the valve element is arranged in the valve cavity and is located between the inlet channel and the outflow channel; a pneumatic cavity is formed in the second shell, and the outer wall of the second shell is provided with an air channel interface communicating with the pneumatic cavityand the outside; the pneumatic part can perform reciprocating motion in the pneumatic cavity under the driving of an external air source and simultaneously drive the valve element to do reciprocatingmotion; and the valve element is suitable for cutting off or opening a passage formed by the inlet channel and the outflow channel when the valve element performs reciprocating motion in the medium cavity, and the movement direction of the valve element is perpendicular to the inlet channel. According to the high-pressure gas-controlled bacteria valve, the flow rate of the medium can be more stable, meanwhile, the valve has the advantages of being high in reliability, high in adaptability and the like.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a high-pressure air-controlled bacteria valve. Background technique [0002] Mushroom valve, also known as bacteria valve, is called bacteria valve because the shape of its valve core is similar to the shape of mushroom fungus. The bacteria valve has the characteristics of simple structure, reliable sealing, fast response, etc., and the most important thing is that the bacteria valve can maintain a good sealing effect under the condition of high pressure in the medium. The known bacteria valve is usually opened by servo motor or manual control of its spool. In actual use, the servo motor has a serious service life problem, and manual control has the problem of wasting labor. [0003] The utility model patent with the notification number CN201599414U discloses a bacterial valve, including a valve seat, an inlet housing, an intermediate housing and a valve core, the valve seat is ...

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the air-controlled bacterial valve in the prior art will cause the medium flow rate to be unstable when used, and to provide a high-pressure air-controlled bacterial valve with a more stable flow rate.
