A New Pneumatic Valve Actuator

Abstract

The invention relates to the technical field of pneumatic valves, and discloses a novel pneumatic valve actuator, which includes a casing, a cover, an air delivery plate, a gas cover and an actuator body. The top of the casing is provided with an air delivery plate. The top of the gas transmission plate is provided with an air hood, and the top of the air hood is provided with an air inlet, the inside of the air inlet is covered with a filter, the inside of the air hood is provided with a fan, and the front of the casing is Both the side and the back side are provided with plate grooves, the plate grooves are built with a mesh plate, the inside of the mesh plate is covered with a dust-proof net, the middle part of the right side of the casing is opened with a first shell groove, and the casing There are rod grooves all around on the right side. The invention adopts a quick connection method through the connection between the casing and the casing. When the actuator needs to be disassembled and overhauled, it can quickly drive the casing to separate from the casing, thereby facilitating the maintenance of the actuator body installed in the casing. Greatly improve the convenience in the process of overhauling the actuator body.

Description

A new type of pneumatic valve actuator technical field [0001] The present invention relates to the technical field of pneumatic valves, in particular to a novel pneumatic valve actuator. Background technique At present, pneumatic actuators are actuators that use pneumatic pressure to drive opening and closing or regulating valves, also known as pneumatic actuators. Mechanism or pneumatic device, but it is generally called a pneumatic head, and pneumatic actuators are sometimes equipped with certain auxiliary devices. Commonly used are valve positioner and handwheel mechanism. The function of valve positioner is to use the feedback principle to improve the performance of the actuator. can, so that the actuator can achieve accurate positioning according to the control signal of the controller. The function of the handwheel mechanism is when the control system stops due to When electricity, gas stop, no output of the controller or failure of the actuator, it can be used...

AI Technical Summary

Problems solved by technology

[0003] The traditional pneumatic actuator is set in a sealed casing. When the pneumatic actuator is damaged and needs to be repaired, the pneumatic actuator needs to be disassembled as a whole. Since the pneumatic actuator casing is fixed by bolts, the disassembly process is cumbersome and cannot be formed quickly. Troubleshooting problems caused a lot of inconvenience to maintenance personnel, and the existing pneumatic actuators do not have a heat dissipation mechanism. When the pipeline transports hot substances, the heat transfer will transfer the temperature to the interior of the pneumatic actuator, which will affect the internal electrical components. Cause damage, greatly reducing the service life of the pneumatic actuator, for this we propose a new type of pneumatic actuator
