A butterfly valve assembly machine

Abstract

The invention relates to a butterfly valve assembling machine. The butterfly valve assembling machine is characterized by comprising a rack, a removable valve body positioning clamp, a removable valve plate positioning clamp, a removable valve seat positioning clamp, a valve shaft oil cylinder ejector, a lower valve shaft electric wrench ejector and an electric control box, wherein the valve shaft oil cylinder ejector and the lower valve shaft electric wrench ejector are positioned on the left and right sides of the valve body positioning clamp respectively; the valve body positioning clamp comprises a cylindrical valve body positioning sleeve and a strip-shaped bottom plate; the cylindrical valve body positioning sleeve is used for positioning and supporting a circular ring body part of the valve body and shares a central line with the circular ring body part; the strip-shaped bottom plate is fixedly connected to the bottom of the valve body positioning sleeve and is provided with a flange supporting frame which is supported through a plurality of elastic support columns; the valve plate positioning clamp is fixedly arranged in a cavity of the valve body positioning sleeve; the valve seat positioning clamp comprises a cylindrical valve seat positioning sleeve; a top surface of the valve seat positioning sleeve is connected with a piston rod of a holder pressing oil cylinder; rocker arms with chucks are symmetrically arranged on the left and right sides of the valve seat positioning sleeve; the holder pressing oil cylinder and a shaft pressing oil cylinder are electrically connected with the electrical control box through a holder pressing electromagnetic valve and a shaft pressing electromagnetic valve respectively.

Description

technical field [0001] The invention relates to a butterfly valve assembly device, in particular to a butterfly valve assembly machine. 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, and good fluid control characteristics. They are also used in cooling water for thermal power plants system. Butterfly valves are generally used in cylindrical passages. 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, and inserts through the shaft holes of the upper and lower valve necks ...

AI Technical Summary

Problems solved by technology

Due to the irregular manual force, not only the coaxiality of the installed valve body, valve seat and valve plate shaft hole is difficult to guarantee, but also the structural parts are easily damaged due to beating, which affects the product quality, especially the labor intensity is high during operation. It consumes manpower and working hours, and the noise is loud, which seriously affects the production environment, reduces production efficiency and increases production costs

Although valve seat and valve shaft assembly machines have been introduced in recent years, they are also operated independently. The transportation of assembly parts and the replacement of fixtures consume time and manpower, and still cannot meet the requirements of assembly quality.
