Rapid grinding device of stop valve

Abstract

The invention discloses a rapid grinding device of a stop valve. The rapid grinding device comprises the stop valve. A fixed sleeve is mounted at the top end of the outer portion of the stop valve ina clamped connection manner. A moving sleeve is embedded and mounted in the fixed sleeve in a sleeved connection manner. The moving sleeve and the fixed sleeve are fixedly connected through a locatingkey. A transmission rod is embedded and mounted in the moving sleeve. A grinding head is mounted at the bottom end of the outer portion of the transmission rod in a clamped connection manner. An electric hand drill is mounted at the top end of the outer portion of the transmission rod in a clamped connection manner. The top end of the outer wall of the transmission rod and the moving sleeve are fixedly connected through a bearing, and a bearing backup cap is fixedly mounted on one side of the bearing. The moving sleeve and the fixed sleeve are connected and fixed through the locating key, theinterior of the moving sleeve is subjected to limiting and connecting through a dovetail groove in the fixed sleeve, the moving sleeve can move up and down and be fixed in the fixed sleeve, and therefore the height of the grinding head is adjusted and fixed, and the different requirements of the device for the inner grinding depth of the stop valve are met.

Description

technical field [0001] The invention relates to the technical field of valve seat repair devices, in particular to a quick grinding device for a stop valve. Background technique [0002] Globe valves are widely used in all walks of life and have become an indispensable product in our production and life. Due to poor product quality, long service life and improper operation, internal leakage of valves is common. In order to save national resources and enterprise funds, it is necessary to grind and repair internal leakage valves, but there are "three difficulties" and "three difficulties" in repairing internal leakage valves. "Three fees" problem, in order to save national resources and improve the economic benefits of enterprises, this stop valve quick grinding device is designed. [0003] However, the existing stop valve grinding device cannot realize the adjustment and fixation of the height of the grinding head in use, the device cannot meet the different requirements for...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a quick grinding device for stop valves to solve the problem that the existing stop valve grinding devices proposed in the above background technology cannot realize the adjustment and fixation of the height of the grinding head, and the device cannot meet the internal grinding requirements of the stop valve. The different requirements of the depth cannot maintain the smooth and uniform grinding power transmission of the drive rod, resulting in poor grinding quality inside the globe valve.
