High pressure safety valve detection system

Abstract

The invention relates to a high pressure safety valve detection system which comprises a control system and a water tank; the control system is respectively connected with a pressure sensor, an electric pressure-regulating valve, a first solenoid valve, and a second solenoid valve; the pressure sensor is connected with a double-needle pressure gauge; the first solenoid valve and the second solenoid valve are in parallel connection, and are connected to a first air filter; two ends of the first air filter are respectively connected with a first driving air inlet and the electric pressure-regulating valve; the other end of the electric pressure-regulating valve is connected with a first governing valve; the first governing valve is connected with a booster pump and a second governing valve; the second governing valve is connected with a manual pressure-regulating valve; a pressure gauge is mounted on the manual pressure-regulating valve; the manual pressure-regulating valve is connected with a second air filter; the second air filter is connected with a second driving air inlet. The beneficial effects of the invention are that: high-precision calibration of the high pressure safety valve is realized; the automation level is high; all operations of the operators can be performed only at a measurement and control bench after all is in order; the labor intensity is decreased, and the safety hidden danger is reduced.

Description

technical field [0001] The invention relates to the field of pressure detection equipment, in particular to a high-pressure safety valve detection system. Background technique [0002] The safety valve is an important safety accessory of pressure-bearing special equipment, and the national safety calibration regulations should be calibrated at least once a year. In recent years, with the rapid development of industry, ultra-high pressure safety valves have been widely used in industrial production, which plays an important role in ensuring the safe operation of production equipment and preventing accidents. At present, many ultra-high pressure safety valves in China can only be sent abroad for inspection, which takes a long time and costs a lot, causing enterprises to bear high inspection costs. The safety valve calibration system produced in China is only the low-pressure safety valve testing system, and the electric hydraulic pump is used for pressure testing, setting and...

Problems solved by technology

[0003] 1. In order to realize the various functions of the safety valve test, the detection equipment assembled by the electric hydraulic pump is used to connect the scattered equipment in a complex manner, but the final controllable function is relatively simple;

[0004] 2. The pressure and flow that the electric pump can provide are very limited, it can only be used for the test of the low-pressure safety valve, and it cannot be carried out according to the desired boosting rate;

[0005] 3. Without the support of special detection software, parameter setting cannot be performed, and there is no display of real-time pressure curves. All operations are manual operations, and all data displays are obtained by human eyes. In this way, the accuracy of the values degree to be verified

Manual operation is very difficult for the speed control of the pump, and the labor load is greatly increased.

[0006] 4. The electric liquid pump itself is bulky and heavy, which causes the equipment to occupy a large space and is inconvenient to move. The noise of the equipment has a certain impact on the working environment of the laboratory.

The electric hydraulic pump needs oil to lubricate. The long-term use of the pump will cause oil leakage, which will pollute the laboratory environment and make it difficult to maintain the equipment.
