Problems solved by technology

Although the 100kg-class pressure relief valve or safety valve on the market can accurately control the relief pressure, there are two key characteristics that cannot be avoided: the pressure relief flow is too small, and the response time is too long (20-50ms) ), so the pressure relief speed cannot meet the test requirements

Embodiment 1

[0034] like figure 1 As shown, the present invention proposes a quick pressure relief test device:

[0035] The oil control cavity 1 is pre-filled with hydraulic oil, and the oil control cavity 1 is provided with an oil delivery port 11, an oil pressure port 12 and an oil drain port 13; the oil drain cavity 2 is connected with the oil drain port 13 on the oil control cavity 1 connection; the oil delivery port 11 on the oil control cavity 1 is connected with the hydraulic machine 8 through the high-pressure pipe 7, and is used to obtain the hydraulic oil required for the test; the high-pressure pipe 7 is provided with a check valve 9, which is used to prevent the return flow of the hydraulic oil; through a The preset force presses the oil plug 6 into the oil drain cavity 2 to seal the oil drain port 13; 12 is through-connected to seal the oil control cavity 1 into a closed cavity with the oil plug 6, the hydraulic machine 8 and the high-pressure pipe 7, and the hydraulic machi...

Embodiment 2

[0042] This embodiment provides a pressure relief test system, including figure 1 The pressure relief test device shown; the pressure relief test system also includes a sealed explosion-proof box, which will be as figure 1 The pressure relief test device shown is enclosed therein, which is used to improve the safety of the performance test of the accumulator, for example, to prevent hydraulic oil from splashing and metal debris from ejecting during the test of the accumulator.

[0043] Preferably, the sealed explosion-proof box is also provided with transparent explosion-proof glass, which is convenient for outside personnel to observe the state inside the box.

[0044] In summary, the present invention proposes a pressure relief test device, which is applied to the performance test of the accumulator, including the oil control cavity, the oil discharge cavity, the hydraulic press and the oil plug, and the oil control cavity is provided with an oil delivery The hydraulic mach...

Abstract

The invention relates to the field of pressure relief testing, and particularly relates to a pressure relief test device which is applied to the performance test of an energy accumulator. The pressure relief test device comprises an oil control cavity, an oil drainage cavity, a hydraulic machine and an oil plug. The oil control cavity is provided with an oil transportation port, an oil pressing port and an oil drainage port. The hydraulic machine is connected with the oil control cavity in a communication way via the oil transportation port. The oil plug is pressed in the oil drainage cavity by preset force so as to seal the oil drainage port. The energy accumulator is connected with the oil pressing port of the oil control cavity in the communication way via a flange in testing, and pressurization is performed on the sealed cavity by the hydraulic machine so that the energy accumulator is enabled to accumulate energy. When pressure intensity in the sealed cavity is greater than a preset value, the oil plug falls off and hydraulic oil is drained into the oil drainage cavity via the oil drainage port so that rapid pressure relief of which oil drainage time is less than or equal to 3ms is realized. The invention also relates to a pressure relief test system which comprises the pressure relief test device. Besides, a sealed explosion-proof box is arranged outside the pressure relief test device.

Description

technical field [0001] The invention relates to the field of pressure relief testing, in particular to a pressure relief testing device and system. Background technique [0002] In the process of designing the accumulator, an important performance index needs to be defined, which is to verify the safety and reliability of the accumulator when the peripheral pressure is suddenly released. Although the 100kg-class pressure relief valve or safety valve on the market can accurately control the relief pressure, there are two key characteristics that cannot be avoided: the pressure relief flow is too small, and the response time is too long (20-50ms) ), so the pressure relief speed cannot meet the test requirements. Contents of the invention [0003] In view of the above problems, the present invention proposes a pressure relief test device, which is applied to the performance test of the accumulator, including: [0004] The oil control cavity is pre-injected with hydraulic oi...
