Abstract

The invention relates to the technical field of pneumatic executers, and discloses a pneumatic executer not influenced by loads. A machine body is included. The front face of the machine body is fixedly provided with a control switch. An air inlet is formed in the top of the control switch. An air outlet is formed in the left side of the control switch. The position, located above the air outlet,of the left side of the control switch is provided with a connecting inserting port. The left side and the right side of the machine body are fixedly provided with side covers. According to the pneumatic executer not influenced by loads, through the arrangement of a cushion plate, when the pneumatic executer goes wrong, fixing nuts are loosened, limitation of upper parts of studs is released, then, the studs are unscrewed and pulled out of the machine body, then, the cushion plate is rotated, the cushion plate moves upwards along with a thread of a connecting screw, moving is conducted to a certain height, then a tool is clamped in a wedged groove, a connecting block is unscrewed, accordingly, a conveying channel is closed, then, a pneumatic execution mechanism is manually adjusted, and the situation that output excess happens, and economic losses are caused is avoided.

Description

technical field [0001] The invention relates to the technical field of pneumatic actuators, in particular to a pneumatic actuator not affected by load. Background technique [0002] The pneumatic actuator is an actuator that uses air pressure to drive the opening and closing or adjusting the valve. It is also called a pneumatic actuator or a pneumatic device, but it is generally called a pneumatic head. The actuator and the adjustment mechanism of the pneumatic actuator are a unified whole. , its actuators include membrane type, piston type, shift fork type and rack and pinion type. The fork-type pneumatic actuator has the characteristics of large torque, small space, and the torque curve is more in line with the torque curve of the valve. , and the advantages of safety and explosion-proof. [0003] Most of the traditional pneumatic actuators no longer carry manual mechanisms, so that they cannot operate when there is a power failure or a problem with the control mechanism...
