Description

Technical Field

[0002] The valve electric device is an indispensable driving device for realizing valve programming, automatic control and remote control. Its movement process can be controlled by the size of stroke, torque or axial thrust. According to today's usage requirements, an explosion-proof valve electric device is needed.

[0003] For example, an explosion-proof valve electric device with application number 202120497449.9, this utility model relates to the technical field of explosion-proof valve electric devices. Through the cooperation between the round rod, the sliding sleeve and the sliding rod, when the user disassembles the device, he only needs to turn the first handle, and the first handle drives the screw to rotate when it turns. Since the spring is in an extended state at this time, the screw can ensure that the vertical plate is always in contact with the screw when it rotates. When the round rod is out of the through hole of the vertical rod, the device can be removed for repair and maintenance. The whole process is simple and quick, which solves the problem that the existing device is inconvenient to disassemble for repair and maintenance during work, and improves work efficiency. However, when installing and debugging the valve electric device body of this device, like most electric devices, it is necessary to remove multiple fixing screws to open the debugging cover and the mechanical cover for debugging and maintenance, which is more troublesome.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a common explosion-proof valve electric device is proposed. Utility Model Content
