Special equipment for valve pressure test

Abstract

The invention relates to special equipment for a valve pressure test, and the equipment comprises a pressure chamber unit, a test interface, a block valve, a water inlet, a pressing device, an exhaust port, a drain port, an opening valve, a first pressure detection device, a second pressure detection device, and a central control module. According to the invention, the upper part of the pressure chamber unit is provided with a plurality of groups of test interfaces with different nominal diameters, valves with different specifications can be detected, the upper part of the pressure chamber unit is also provided with an exhaust port, gas in the pressure chamber unit is discharged in time, the stability of the pressure environment in the pressure chamber unit is ensured, and the detection efficiency is improved. Damage to the detected valve due to pressure fluctuation is avoided, meanwhile, an opening valve is arranged in the water drainage opening, the stability of the pressure environment in the pressure chamber unit is kept by controlling the opening, the accuracy of the valve test result is further improved, and the accuracy of the valve test result is further improved by arranging a central control module to intelligently control all parts. And the valve testing efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of intelligent measurement and control, in particular to a special equipment for valve pressure test. Background technique [0002] When the valves are in use, they need to be installed and used after a pressure test according to the requirements of the national standard. However, this problem is generally ignored on the construction site at present. Due to the large number of valves, it is extremely cumbersome to press them one by one. The work tasks are heavy, and there are often operations on site. If it is not in place, this will affect the quality management of the valve entry inspection, and the number of problems behind the valve will increase, increasing the probability of valve leakage. [0003] In the prior art, when multiple tests are performed on the pressure tightness of valves, the accuracy of the test results for each valve is often low due to the instability of the test environment, which can...
