High-stability anti-explosion valve

Abstract

The invention discloses a high-stability anti-explosion valve. The high-stability anti-explosion valve comprises a controller assembly and a pneumatic head. The controller assembly comprises an upper control module and a lower control module. The upper control module comprises a shell, an upper cover, solenoid valves, a terminal block and a signal feedback mechanism. The lower control module comprises an anti-explosion shell, an anti-explosion end cover, an air source treatment device and an integrated air exhausting device. The lower control module is mounted on the front face of the pneumatic head, and the upper control module is mounted at the top of the pneumatic head. The shell is internally provided with an air channel integrated block. The solenoid valves comprise the first solenoid valve and the second solenoid valve. The first solenoid valve and the second solenoid valve are connected to the air channel integrated block. The air channel integrated block is further connected with a mechanical valve. The anti-explosion shell is internally provided with a first pneumatic control valve, a second pneumatic control valve and an air channel block. The first solenoid valve and the second solenoid valve are connected with two control ends of the second pneumatic control valve through air pipes correspondingly. The high-stability anti-explosion valve is of an integrated structure, high in stability, capable of saving energy consumption, high in control precision, good in anti-explosion performance, not prone to leakage and free of maintenance.

Description

technical field [0001] The invention relates to a valve, in particular to a high-stability explosion-proof valve. Background technique [0002] At present, ordinary explosion-proof valves often require on-site PC or industrial computer to control, and the low control precision causes the valve to be easily damaged, which has the disadvantages of cumbersome use and debugging, difficult maintenance, and high control costs; and such valves are generally controlled by solenoid valves. Pneumatic actuator action, long power-on time and poor airtightness, thus reducing its explosion-proof performance. [0003] In addition, the existing gas circuit control valve has messy connection of gas pipes, exposed gas pipes, easy leakage, short service life, troublesome maintenance, and is difficult to apply to places with harsh explosion-proof conditions. SUMMARY OF THE INVENTION [0004] In order to solve the above-mentioned defects and deficiencies in the prior art, the present inventio...

Problems solved by technology

[0002] At present, ordinary explosion-proof valves often need to be controlled by a PC or industrial computer on site. The low control accuracy causes the valve to be easily damaged, and has the disadvantages of cumbersome use and debugging, difficult maintenance, and high control costs; moreover, such valves are generally controlled by solenoid valves. Pneumatic actuator action, long power-on time, poor airtightness, thus reducing its explosion-proof performance

[0003] Moreover, the existing gas circuit control valves have messy air pipe connections, exposed air pipes, easy to leak, short service life, and troublesome maintenance. It is difficult to apply to places with strict explosion-proof conditions.
