Abstract

The invention provides a piston type vacuum coaxial valve with vacuum as a power air source. The piston type vacuum coaxial valve comprises a piston type valve element, an air cylinder barrel, pressing blocks, sealing blocks, sealing rings, a sealing valve seat and an electromagnetic control device. The piston type valve element is in a barrel shape, is arranged in the air cylinder barrel in a sleeved manner and can do reciprocating motion. The sealing blocks are arranged at the two ends of the air cylinder barrel and used for sealing a sealing gap between the piston type valve element and the air cylinder barrel. The pressing blocks are arranged at the outer ends of the sealing blocks and used for pressing the sealing blocks tightly. The sealing valve seat is arranged at the outlet end of the piston type valve element and used for sealing an end opening of the piston type valve element. The sealing rings are located on mutual contacting faces of the components. By adopting the scheme, it is not needed to externally connect a power air source, the vacuum serves as the power air source, opening and closing of the coaxial valve can be achieved through a small-power two-position three-way solenoid valve, the consumed power is small, and operation is convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of fluid flow valves, in particular to a piston-type vacuum coaxial valve with vacuum as a power source. Background technique [0002] Vacuum solenoid valve refers to the solenoid valve used for vacuum negative pressure system with pressure lower than normal atmospheric pressure. It is suitable for two-position on-off switching actuators in vacuum equipment pipelines. It is widely used in vacuum system pipelines in food, metallurgy and other industries. Its working principle is to use the electromagnetic induction phenomenon to control the pipeline by electromagnetic induction, and use the vacuum principle to make a vacuum structure inside the valve, which can effectively improve the working efficiency of the vacuum solenoid valve. When the medium passes through the pipeline near the vacuum solenoid valve, the medium will send information to the induction device of the vacuum solenoid valve, and the valve wi...
