Auxiliary operating platform for assembling butterfly valve with large specification

Abstract

The invention relates to an auxiliary operating platform for assembling a butterfly valve with the large specification. The auxiliary operating platform is characterized in that a lower bracket, an upper bracket, a crossarm, a screw with a hand wheel, an inserting and pulling pin and an idler wheel are included, the lower bracket is composed of a square tableboard frame, four supporting legs connected to the four corners of the tableboard frame and cross braces connected between the adjacent supporting legs, a butterfly valve bearing plate is placed on the tableboard frame, and the bearing plate is provided with a round hole; the upper bracket sleeving the outer side of the lower bracket is arranged on the upper part of the lower bracket, the upper bracket is composed of a rectangular topframe, front and rear side vertical columns and a crossbar connected between the bottom ends of the vertical columns, and the upper bracket can be movably connected to the lower bracket front and backthrough the idler wheel structure arranged between the two ends of the crossbar of the upper bracket and the cross braces of the lower bracket; the crossarm is a H-shaped frame, and the crossarm is inserted horizontally between the front and rear side vertical columns of the upper bracket and fixed to the selected height of the upper bracket through the inserting and pulling pin; and a pulley isarranged between front and rear side cross beams on both sides of a connecting rod, a vertical thread through hole is formed in the center of the pulley, and the screw with the hand wheel penetrates through the thread through hole and extends to the lower part of the thread through hole.

Description

technical field [0001] The invention relates to an auxiliary process device for producing butterfly valves, in particular to an auxiliary operating platform for assembling large-scale butterfly valves. Background technique [0002] Butterfly valves are widely used in petroleum, gas, chemical, water treatment and other industrial fields because of their simple structure, small size, light weight, convenient and quick opening and closing, labor-saving, and good fluid control characteristics. Butterfly valves are generally used in cylindrical channels. During use, the disc-shaped valve plate is installed along the radial direction of the pipeline, and rotates around the valve shaft between 0° and 90° to achieve full closure and full opening. The butterfly valve mainly includes a circular valve body with upper and lower valve necks, a circular valve seat embedded in the inner wall of the valve, a circular valve plate embedded in the circular valve seat, and a shaft through the u...

AI Technical Summary

Problems solved by technology

The disadvantages of the existing operation are: because the large-sized butterfly valve and the actuator are very large in size, they need to be transported and hoisted repeatedly, and when adjusting the opening and closing position of the valve plate, it is necessary to open the valve plate several times to correct its indicated position , in this process, the operator's movements are frequent, the intensity is high, the consumption is high, time-consuming and laborious, and the efficiency is low, especially there are quality hidden dangers such as bumps and scratches on the product
