Check assembly for hydraulic test of multi-opening disc type piece

Abstract

The invention relates to a check assembly for a hydraulic test of a multi-opening disc type piece. The check assembly comprises upper plugging covers, opening plugging covers, a barrel plugging cover, a base, water inlet joints and pressure-measuring hole plugs, wherein the opening plugging covers have independent structures and are cooperatively used with the upper plugging covers and the barrel plugging cover so as to realize the sealing for the multi-opening disc type piece; the barrel plugging cover is located in the base and is fixedly mounted at the center of the upper surface of a base plate of the base; the upper plugging covers are fixed on the upper surface of the base; the water inlet joints are fixed at the center of the upper surfaces of the upper plugging covers and are communicated with water inlets at the center of the upper plugging covers; pressure-measuring holes are formed on the upper plugging covers; and the pressure-measuring hole plugs are arranged on the pressure-measuring holes. According to the invention, three upper plugging covers with different structures are used for connecting and sealing all the openings of the multi-opening disc type piece; the limiting and fastening are realized; the assembling is convenient; the structure form of separately sealing the multi-opening disc type piece is adopted, so that the separation of a thin-wall circular section and a flange end of the multi-opening disc type piece is realized; and the stressed deformation of the circular section of the multi-opening disc type piece is avoided.

Description

technical field [0001] The invention relates to a testing device for hydraulic testing in the mechanical industry, in particular to a testing tool for hydraulic testing of multi-opening disc shaped parts. Background technique [0002] For the metal disc parts used in the machinery industry, the sealing structure at the front and rear ends generally adopts a radial seal or end face seal structure, and is connected by a flange or a key ring. For products with many openings in the structure, high pressure bearing capacity, and non-load-bearing parts, hydraulic testing and sealing are difficult to solve, and at the same time, it is impossible to completely isolate the non-load-bearing parts. [0003] By searching domestic and foreign patent documents and paper databases, it is found that "a casting pressure detection device with non-parallel upper and lower flange surfaces of the opening of the cavity" (public number: CN105181277A) adopts a follow-up device that abuts against th...
