Fork type pneumatic actuator principle and concept

the era of automation, anything to pay attention to the rapid intelligence, to improve work efficiency, promoting economic development. The actuator as an important part of a process control system. So-called automatic control system of the actuator is the actuator and control valve assembly, role in the automatic control system is to accept from the signal from the regulator, with its position in the process piping and features, regulating the flow of process medium, which will be charged with several control within the scope of the production process required. , of course, the rapid development of science and technology, and so did the actuator drive mode in gradual innovation, also in the extension actuator type. We can tell a ropriating fork type pneumatic actuators. This is a routine piston actuator, applicable ° Angle valves ( Such as ball valve, butterfly and plug valves) Switch to cut off or measurement control. Through compressed air into the cylinder, and promote the fork type piston movement, through the fork to the linear motion of the piston into the rotation of the disc movement, disk drives the output shaft rotation, so as to realize the control of the valve. According to the different types of role, of course, can be divided into single acting fork type pneumatic actuators and double-acting fork type pneumatic actuators. Actuators of switch action is done through the air drive, is the fork type pneumatic actuators with double acting; And only open movement is driven by gas source is complete, close the action for spring reset is single-acting fork type pneumatic actuators. According to the structure of different, can be divided into single cylinder piston and cylinder piston. According to the main material is different, can be divided into the aluminum alloy, stainless steel, carbon steel etc.
