Air bag valve vacuum working condition execution device

Abstract

The air bag valve vacuum working condition executing device comprises a compressor, a condenser, a solution collector and a fin assembly which are sequentially connected through a pipeline, the tail end of the pipeline is in backflow communication with the starting end of the pipeline, and a closed loop is formed by the pipeline and a cavity between a pipe sleeve and a valve body of an air bag valve; an outlet electromagnetic valve is arranged on a pipeline between the compressor and the air bag valve, and an inlet electromagnetic valve is arranged between the fin assembly and the air bag valve. The air bag valve executing device is reliable in structure and good in use performance, effectively achieves rapid and reliable executing operation on an air bag valve under the vacuum working condition, meanwhile, in the executing operation process, the air tightness problems such as blocking and untight closing cannot be caused, and the working technical requirements of the air bag valve can be greatly met.

Description

technical field [0001] The invention relates to the technical field of valve body control, in particular to an air bag valve vacuum working condition actuator. Background technique [0002] The air bag valve is a valve with excellent wear resistance and corrosion resistance, and it is a good substitute for traditional ball valves, butterfly valves, diaphragm valves and other valves. Under vacuum conditions, after the cavity between the pipe sleeve and the valve body is exhausted, the material side of the pipe sleeve is affected by the negative pressure and sticks, and the airbag valve cannot be opened and closed smoothly, which affects material transportation and control, and in severe cases affects process operation. However, traditional pneumatic butterfly valves, pneumatic ball valves, and pneumatic gate valves are affected by material particles, and are prone to clogging and scratching, resulting in lax closure of the valve body and affecting the airtightness of the syst...

Problems solved by technology

Under vacuum conditions, after the cavity between the pipe sleeve and the valve body is exhausted, the material side of the pipe sleeve is affected by the negative pressure and sticks, and the airbag valve cannot be opened and closed smoothly, which affects material transportation and control, and in severe cases affects process operation

However, traditional pneumatic butterfly valves, pneumatic ball valves, and pneumatic gate valves are affected by material particles, and are prone to clogging and scratching, resulting in lax valve body closure and affecting the airtightness of the system.
