Valve comprehensive test system

Abstract

The invention provides a valve comprehensive test system, belonging to the technical field of valve test and solving the problems of narrow applicable scope, high cost and low accuracy in traditional valve comprehensive test system. The valve comprehensive test system comprises a control terminal, water supply modules interconnected via water pipes in sequence, forming a loop and used for supplying water to the loop, a water consumption control module for adjusting the actual water consumption amount in the loop, a test module for the placement of a valve and testing the performances thereof, and a detection module for detecting parameters of the valve during test, wherein the water supply modules, the water consumption control module, the test module and the detection module are all connected with the control terminal, the control terminal can control the water supply amount of the water supply modules and adjust the actual water consumption amount in the water consumption control module, and all the modules can feed own working state back to the control terminal for being processed and displayed. The valve comprehensive test system has the advantages of wide applicable scope, high test precision, supporting electric and manual adjustment and the like.

Description

A comprehensive test system for valves technical field The invention belongs to the technical field of valve testing and relates to a valve comprehensive testing system. Background technique Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, prevention of reverse flow, pressure stabilization, flow diversion or overflow pressure relief. They are widely used in various fields. The quality of the valve will directly affect the quality of the pipeline. The safety and quality of road transportation. If each valve is tested by purely manual operation to ensure its quality, a large amount of manpower is required, which is not only inefficient but also expensive. For this reason, people have designed a kind of constant temperature mixing valve performance test method, and have applied for a patent, (its application number is: 200810243735.1; Its publication number is: CN101419133A), a kind of constant t...

AI Technical Summary

Problems solved by technology

The valve performance test system uses a whole set of systems to test the valve performance. The whole process can be controlled by the electrical control system, and the test results can be processed and displayed by the data acquisition system. The test process is relatively simple, which improves the accuracy of valve detection. Efficiency, however, the application of this system is limited to thermostatic mixing valves, and it cannot be used universally for testing other valves, and the scope of application is small

During the use of the system, multiple fixed water pumps need to be used to control the water flow on each branch, which not only increases the cost of electricity, but also has low accuracy.
