Type of electric pneumatic valve parallel brake is analysed

electric pneumatic valve parallel gate structure is divided into two parts, the upper part is electric actuators, the lower part is a pneumatic valve. Working principle is simple: use pneumatic valve electric actuator control, so as to realize the pneumatic valve is opened and closed.
the two types of electric pneumatic valve:
a trip, a kind of Angle electropneumatic valve: from the Angle of the trip of electric actuator using with Angle of pneumatic valve, pneumatic valve degree. the spin control pipe flow on and off;
2, another for straight travel electropneumatic valve: by straight travel electric actuator with straight travel used pneumatic valve, pneumatic valve plate up and down movement control pipe flow on and off. Which is equipped on a high degree of automation equipment, the level of pneumatic valve installation accuracy is the best.
action moment than electric pneumatic valve, pneumatic valve electric gate switch movement speed can be adjusted, simple structure, easy maintenance, in the process of action for buffer characteristics of the gas itself, is not easy to damage due to get stuck, but must have a gas source, and its control system is more complicated than the electric pneumatic valve. Electric brake pneumatic valve response is sensitive, safe and reliable, a lot of factory of high control requirements for pneumatic instrumentation control components set the compressed air station. Electric is to electricity, and can control the flow of the device.
parallel to the electric brake of pneumatic valve:
can have AI feedback signal, can be controlled by the DO or AO, is seen in large pipe and wind pneumatic valve, etc.
。 Parallel brake switch forms: electric pneumatic valve driver is commonly used motor, need time to open or close action of analog, can do to adjust.
。 Nature of work: parallel to the electric brake of pneumatic valve drive is commonly used motor, voltage impact resistance. Electromagnetic air valve is closed fast and fast, generally used in small flow rate and pressure, asked for a switch frequency big place parallel to the electric brake pneumatic valve and vice. Parallel to the electric brake of pneumatic valve pneumatic valve can control the openings of the state is open, closed, half-open half closed, can control the medium inside the pipeline flow and solenoid pneumatic valve can not reach the requirements.
