Description

Technical Field

[0001] The utility model relates to the technical field of test platforms, in particular to a durability test platform for voltage regulators. Background Art

[0002] During the use of gas transmission and distribution equipment, gas leakage may cause personal harm and property losses. Gas pressure regulators are key components in the gas transmission system, responsible for reducing high-pressure gas to the pressure level required at the user end. To ensure the safety and stability of gas pressure regulators under various usage conditions, durability testing is essential. According to Clause 6.8 of the standard GB27790-2020 "Urban Gas Pressure Regulators", the pressure regulator should undergo durability testing. The gas pressure regulator should, after 30,000 opening and closing actions with a stroke greater than 50% of the full stroke (excluding the closed and fully open positions) at room temperature, have its external seal, pressure regulation accuracy, and closing performance meet the requirements of this specification.

The currently used test platforms are not convenient for conducting durability tests on gas pressure regulators, thus resulting in the inability to ensure the performance and reliability of gas pressure regulators during long-term use, which is not conducive to the subsequent use of gas pressure regulators.

One of the inlet air source speed control valves 3 is connected to the voltage regulator body 1 through an intake pipe 7. A Siemens PLC 8 is installed inside the housing 2.

[0021] A switching power supply 10 is installed inside the housing 2. A three-phase air switch 12 is arranged inside the housing 2. A terminal block 11 is installed inside the housing 2. An inlet solenoid valve relay 15 and an outlet solenoid valve relay 14 are arranged inside the housing 2. A touch screen 16 is installed on the housing 2. A power switch 19, an emergency stop button 17, and a start button 18 are arranged on the housing 2. An inlet pressure gauge 21 is arranged on the housing 2. An air source pressure regulating valve 20 is installed on the housing 2. The touch screen 16 is arranged between the inlet pressure gauge 21 and the power switch 19.

[0022] The Siemens PLC 8 can achieve automatic and precise control, programmable setting of test parameters, adopt advanced control technology to ensure the stability and repeatability during the test process, and can also automatically record test data for easy analysis and report generation. It is convenient to set relevant test parameters by using the touch screen 16, which is easy to set and operate.

[0024] This gas durability test platform is designed to simulate the normal working state of a gas pressure regulator and conduct simulations of the opening and closing states of the equipment.

The compressed gas passes through a gas source triple unit for gas filtration and pressure regulation to provide different inlet pressures that meet the test requirements of the gas pressure regulator. The test inlet pressure range is 0.05 - 1.6 MPa. The compressed air is reduced in pressure to low-pressure gas by the pressure regulator body 1. The valve port of the pressure regulator body 1 is closed, and then the inlet solenoid valve 4 is closed and the outlet solenoid valve 6 is opened. The gas at the rear end of the pressure regulator body 1 is discharged to the atmosphere. Then the valve port of the pressure regulator body 1 is opened again. Each opening and closing is regarded as a cycle. At the same time, the inlet gas speed of the gas source can be adjusted by the inlet gas source speed control valve 3 to avoid impact on the pressure regulator body 1. This equipment is configured with a gas source triple unit, a Siemens PLC 8, an inlet solenoid valve 4, an outlet solenoid valve 6, a touch screen 16, an inlet pressure gauge 21, electrical components and other components, which is convenient for setting equipment parameters and information display and interaction. The test cycle of the equipment can be set to 30,000 times by default according to the standard, or it can also be set manually.
