Pressure regulator static characteristic detection system

Abstract

The invention relates to a modulator static feature testing system. It comprises the air storage can, flow meter, first level pneumatic valve and the second level pneumatic valve, several ball valves and several tunnels connected by bolts. The first level pneumatic valve comprises the main body and the instructor connected by signal block and quick joint phase. The first level pneumatic valve comprises the main body and the instructor connected by signal block and quick joint phase. A manometer is set at each outlet of the air storage can, first level pneumatic valve, flow meter, modulator to be tested, with all the manometers, first level pneumatic instructor, needle shape valve of the second level pneumatic valve and discharge valve on the control platform, connected to corresponding positions of the testing system through signal tube, quick joint. It is stable in testing, accurate, short in process, less in pneumatic consumption, and labor saving.

Description

Technical field [0001] The invention relates to a performance detection system of special equipment, in particular to a performance detection system of pressure regulating equipment. Background technique [0002] The existing pressure regulator static characteristic detection system includes a gas storage tank, a glass rotameter group, several pressure gauges and several ball valves, which are connected in series through pressure pipes. The detection system is constructed as follows: the outlet of the gas storage tank is provided with a gas storage tank outlet pressure gauge, and each glass rotameter is equipped with a flowmeter inlet butterfly valve and a flowmeter outlet butterfly valve at both ends of the glass rotameter group. There are flowmeter inlet pressure gauges and flowmeter outlet pressure gauges respectively at the end of the flowmeter, an exhaust valve is installed at the outlet of the glass rotameter group, and a pressure regulator outlet pressure gauge is ins...

AI Technical Summary

Problems solved by technology

[0004] The defects of this detection system are: 1. Many people are needed to detect the performance of the voltage regulator

2. The detection takes a long time, and the detection data is not easy to be accurate, and the gas source is wasted a lot

Since three people are adjusting at the same time during the test, it is difficult to achieve a tacit understanding so that the pressure at the inlet and outlet of the pressure regulator under test can accurately reach the required value at the same time, so the test time is long and the data is not easy to be accurate. will waste a lot of gas

3. Since the control switches of the detection system are all large valves directly installed in the pipeline, it is difficult to operate during detection and it is not easy to fine-tune
