AI Technical Summary

Technical Problem

Existing check valve processing equipment is prone to valve disc displacement during check valve disc processing, affecting processing accuracy and efficiency.

Method used

A high-sealing CV-type check valve disc processing equipment was designed. It uses a hydraulic rod to drive the arc-shaped limit block to cooperate with the top block, combined with small wear-resistant blocks to increase friction. The guide hole and guide rod ensure the stability and accuracy of the limit block movement. It is also equipped with a motor to drive the worktable to rotate, providing stable processing power.

Benefits of technology

It effectively prevents valve disc displacement, improves machining accuracy and efficiency, extends motor life, reduces machining errors and equipment vibration, and enhances machining stability and reliability.

Abstract

This utility model discloses a valve disc processing device for a strong-sealing CV-type check valve, comprising a device body, a mounting cabinet, a worktable, and a positioning and fixing device. The worktable is located on top of the mounting cabinet, and the positioning and fixing device is installed on top of the worktable. The positioning and fixing device includes a first positioning device and a top block. The first positioning device is installed on the left side of the top of the worktable, and the top block is installed on the right side of the top of the worktable by screws. A rubber wear-resistant gasket is installed on the left side of the top block. The first positioning device includes a main board, a hydraulic rod, and a limit block. The limit block is located on the right side of the main board, and the hydraulic rod is installed on the left side of the main board. The driving end of the hydraulic rod is connected to the left end of the limit block. The limit block has an arc-shaped structure, and several sets of small wear-resistant blocks are provided on the inner side of the limit block. The small wear-resistant blocks have a rectangular structure. This device can effectively solve the displacement problem during valve disc processing in the prior art.
