Do you think in vacuum exhaust valves and electronic valve which good?
each has his strong point: vacuum exhaust valve is to use electromagnetic control of industrial equipment, is used to control the fluid automation components, belonging to the actuator, is not limited to hydraulic, pneumatic. Electric valve, in a nutshell is to use control valve electric actuator, so as to realize the valve opened and closed, also called air valve.
pneumatic valve automatic controller is also called valve pneumatic actuators, by adding the form of electromagnetic valve, to automatically control the in and out of the gas, so as to achieve the function of the valve open and close automatically. At present, the pneumatic valve automatic control for wycombe double fork type pneumatic actuators is more, because of its internal fork type design, wear small, more resistance to use! And are more accurate control!
1, the switch action
the switching action of double-acting cylinder are carried out through the air to drive; Ventilation, ventilation, barely able to keep the in situ; Single-acting switch action only open action is air driven, and close the action is spring return.
2, type,
the single-acting points: normally open and normally closed.
normally open type points: ventilation, barely able to open; Normally closed type: ventilation, gave up the ghost.
3,
single function of single than double action. Such as double function can meet the three five, achieve security functions such as medium voltage, but the single-acting cannot achieve this function.
4, the working principle of
double function: when the air pressure between two port into the cylinder piston lumen, separate the two piston to move on both ends of the cylinder, both ends of the air chamber through the discharge port, at the same time make the two piston rack and synchronous drives the output shaft ( The gear) Counterclockwise.
single function: when the air pressure between two port into the cylinder piston lumen, separate the two piston to move on both ends of the cylinder, force on both ends of the spring compression, both ends of the air chamber through the discharge port, at the same time make the two live rack synchronous drives the output shaft ( The gear) Counterclockwise.
