Rapid installing device for valve handle

Abstract

The invention discloses a rapid installing device for a valve handle. The rapid installing device for the valve handle comprises a cylinder, a round plate, a first motor, connecting rods, an annular block, strip-shaped sliding grooves, long screw rods, a sliding block, second motors, traction square blocks, strip-shaped holes, a strip-shaped plate, Z-shaped clamping blocks, V-shaped grooves, a hexagonal hole round pipe, the round handle and a sealing cover. The rapid installing device for the valve handle is reasonable in design, the distance between two clamps can be changed conveniently to clamp some valve handles with different diameters and sizes, the inconvenience of hand-hold installation and placement is solved, the function of rapidly installing the valve handle is realized, the installing work efficiency is improved, and the rapid installing device for the valve handle is suitable for installation, detachment and replacement of the valve handle. Through opposite-direction identical-speed movement of the two traction square blocks, one ends of the two Z-shaped clamping blocks with the V-shaped grooves are driven to get close to the surface corresponding to the round handleof a valve in the opposite directions, and the round handle is clamped and fixed through the V-shaped grooves.

Description

technical field [0001] The invention relates to a quick installation device, in particular to a quick installation device for a valve handle, belonging to the technical field of valve applications. Background technique [0002] Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, and stainless steel valves according to their materials. Chromium molybdenum steel valves, chrome molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard custom valves, etc. [0003] The handles of some valves are circular or plate-shaped. Generally, when installing or replacing valve handles, first insert the circular handle with a hole in the middle on the valve through the hole to pull the rotating threaded column. Then put the nut on the threaded column and tighten it with tools, and the opera...

Problems solved by technology

[0003] The handles of some valves are circular or plate-shaped. Generally, when installing or replacing the valve handles, first insert the circular handle with a hole in the middle on the valve through the hole to pull the rotating threaded column. Then put the nut on the threaded column and tighten it with tools, and the operation steps are cumbersome, and the round handle will also be tilted due to improper fastening method, which will affect the use. At the same time, hold valve handles of different specifications to place and install There are laborious and unstable operations due to the heavy mass, resulting in slower installation
