Description

Technical Field

[0001] This application relates to the field of test bench technology, and in particular to a ventilation explosion-proof test bench for high-pressure ventilation testing. Background Technology

[0002] High-pressure valves are widely used in aerospace, chemical, and other fields. Ventilation testing is essential in the development of high-pressure valves. This testing requires various pressure vessels, whose internal pressures typically reach 35 MPa or even higher, making the high-pressure ventilation test inherently dangerous. Furthermore, during the test, as the internal pressure of the pressure vessel gradually increases, the surface temperature of the pressure vessel also rises significantly.

[0003] Existing patent publication number CN104979025B discloses a structural integrity test platform for reactor pressure vessels under IVR conditions. It includes a condition simulation system, a data acquisition and analysis system, and a safety system. The condition simulation system is equipped with a water supply unit, a steam condensation unit, and a heating unit; the data acquisition system consists of measuring elements from each unit; and the safety system is located around the condition simulation system. This invention simulates the boiling heat transfer process of a reactor pressure vessel by controlling the flow rate of water in the cooling unit and the heating power of the hot pool simulation unit. It analyzes the heat transfer characteristics of the simulated reactor pressure vessel by measuring the vessel wall temperature, strain, and pressure, providing a reference model for boiling heat transfer tests of reactor pressure vessels. However, its structure is complex and its ventilation effect is poor.

[0004] Currently used test benches lack protective measures for pressure vessels such as gas cylinders. In the event of leaks or other problems, they can easily damage surrounding test equipment and personnel. Furthermore, during the test, as the pressure inside the pressure vessel gradually increases, the surface temperature of the pressure vessel also rises significantly. Currently used test benches lack effective heat dissipation measures and cannot cool the pressure vessel in time, affecting test efficiency.

[0005] Therefore, the urgent technical problem to be solved is how to provide a ventilated explosion-proof workbench for high-pressure ventilation tests that has a simple structure, explosion-proof function, and facilitates heat dissipation from the surface of the pressure vessel, so as to conduct high-pressure ventilation tests on the pressure vessel more safely and efficiently.

[0006] The purpose of this application is to provide a ventilated explosion-proof workbench for high-pressure ventilation testing. It has a simple structure, explosion-proof function, and facilitates heat dissipation from the surface of the pressure vessel, making it safer and more efficient for conducting high-pressure ventilation tests on the pressure vessel.

[0007] To achieve the above objectives, this application provides a ventilated explosion-proof workbench for high-pressure ventilation testing, comprising: a platform, support legs, a housing, and an electric fan.

When the electric fan is started, it drives the air inside the cavity to exchange and circulate with the air outside the housing.

[0008] The ventilation explosion-proof workbench for high-pressure ventilation testing as described above has a grid opening on the side of the housing; the air pipe of the pressure vessel passes through the grid opening.

[0012] The ventilation explosion-proof workbench for high-pressure ventilation testing, as described above, has an observation port on the housing.

[0013] As described above, the ventilated explosion-proof workbench for high-pressure ventilation testing includes electric fans installed on two opposing first side panels or two second side panels.

[0032] like Figure 1 and 2 As shown, the platform 1, the first side plate 3, the second side plate 4, and the cover plate 5 are all provided with multiple through holes 7, which are evenly spaced apart.

[0034] like Figure 1 and 2 As shown, electric fans 6 are installed on two opposing first side panels 3 or two second side panels 4.
