Valve actuator convenient to mount and dismount and using method thereof

Abstract

The invention provides a valve actuator convenient to mount and dismount and a using method of the valve actuator convenient to mount and dismount, and relates to the technical field of valve actuators. A driving mechanism is installed on the box body, a control box is installed on the front end face of the box body, and a baffle piece is installed at a box opening in the front side of the control box; a one-way transmission mechanism is arranged on the right side of the rear end face of the box body, and an oil storage tank is installed on the rear end face of the box body and communicates with the interior of the box body. Through the arrangement of the baffle piece, the sealing top plate and the fastening hand wheel, when the baffle piece and the sealing top plate are disassembled and assembled, a large number of bolts do not need to be rotated through a tool, and therefore more convenience is achieved; the worm and the worm gear can be well lubricated; the problems that an existing valve actuator is very inconvenient to overhaul, and a worm gear and a worm in an upper box body of the existing valve actuator cannot be well lubricated are solved.

Description

technical field [0001] The invention relates to the technical field of valve actuators, in particular to a valve actuator that is easy to install and disassemble and a method for using the same. Background technique [0002] Valve actuator refers to the machinery that drives the valve with energy such as electric energy. It is divided into multi-turn, partial-turn, straight-through, angle-through, etc. When the valve actuator is overhauled, it is usually necessary to cover the sealing plate and other structures. Disassemble. [0003] However, when the existing valve actuator is overhauled, a large number of bolts need to be rotated by tools, which makes it very inconvenient to disassemble and install the sealing plate on the valve actuator, and the existing valve actuator is not shipped before leaving the factory. Although the worm gear and worm in the box will be lubricated by lubricating oil, after the valve actuator is used for a long time, the lubricating oil on the wor...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing valve actuators are overhauled, a large number of bolts need to be rotated by tools, which makes it very inconvenient to disassemble and install the sealing plate on the valve actuators, and the existing valve actuators before leaving the factory, Although the lubricating oil will be used to lubricate the worm gear and worm in the box, after the valve actuator is used for a long time, the lubricating oil on the worm gear will drop to the inner bottom surface of the box under the action of gravity, so that the worm gear Without better lubrication, the wear efficiency of the worm gear will be increased, thereby reducing the service life of the valve actuator
