Device for opening and closing high temperature valve

Abstract

The invention discloses a device for opening and closing a high temperature valve. The device mainly comprises an intelligent control motor, a transition component, an opening and closing executer and a digital display instrument, wherein the transition component consists of a transition shaft rod and a wall penetration tube sleeved on the transition shaft rod; the opening and closing executer consists of a worm wheel box, a driven shaft rod, a torque sensor and a supporting frame; the driven shaft rod is axially matched with a through hole in a worm wheel in a sliding manner; the outer end of a worm is connected with one end of the transition shaft rod through a flexible soft shaft; the other end of the transition shaft rod is connected with the output shaft of the intelligent control motor; the intelligent control motor and the digital display instrument are positioned in a normal temperature region; and the opening and closing executer is positioned in a high temperature region. The device can open and close the valve in a high temperature environment successfully and control an opening moment and a closing moment, has a compact structure, a small volume and light weight, can be conveniently arranged on a valve body, and can also be disassembled frequently to adapt to replacement of valves.

Description

technical field [0001] The invention relates to a valve opening and closing device, in particular to a high temperature valve opening and closing device, in particular to a high temperature valve opening and closing device whose opening and closing torque can be controlled. Background technique [0002] In the prior art, there are many control technologies and related products related to the opening and closing torque of valves, and most of the existing valve opening and closing devices have the function of controlling the opening and closing torque. However, the existing valve opening and closing devices are only suitable for use in normal temperature environments. In a high temperature environment around 200°C, they cannot work normally, and cannot open and close the high temperature valve smoothly. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects in the existing valve opening and closing device, and prov...
