Problems solved by technology

[0002] The pressure vessel of the enterprise will age after a long time of production, and the aged pressure vessel is prone to leakage accidents during use, which will affect the safe production of the enterprise
[0003] At present, the airtightness of the pressure vessel is generally detected by injecting gas into the pressure vessel on the market. By observing the pressure change in the pressure vessel, it is judged whether the pressure vessel leaks. However, in the actual operation process, when the upper gap of the pressure vessel is relatively large Hours, the pressure change in the pressure vessel is small, and it is difficult for the detection instrument on the ordinary pressure vessel to accurately judge the air pressure change in the pressure vessel, and the error is large

Embodiment 1

[0014] Example 1: Such as figure 1 A leak detection device for a pressure vessel is shown, the detection device includes a fixed platform 1, a vacuum pressure pump 2 and a control detection platform 3, and the vacuum pressure pump 2 is connected to the control detection platform 3 through a connecting pipeline 8 On the top of the control testing platform 3, a pressure pipeline 5 is provided, and the side of the control testing platform 3 is provided with a pressure monitoring circuit 6. The connecting pipeline 8 is connected to the inlet of the pressure vessel through the pressure pipeline 5. On the air port, the top of the pressure monitoring line 6 is provided with a sealed end, the pressure monitoring line 6 is connected to the gas outlet of the pressure vessel through the sealed end, and the top of the sealed end is provided with a pressure sensor 9. The pressure sensor 9 is connected to the detection console 3 through the pressure monitoring line 6 .

Embodiment 2

[0015] Example 2: Such as figure 1 As shown, the upper part and the side of the control detection platform 3 are provided with a rotating winding disk 7, and the pressure monitoring circuit 6 and the pressure pipeline 5 are all coiled on the rotating winding disk 7; The disk 7 is used to wind the pressure monitoring circuit 6 and the pressure pipeline 5 with a relatively long length, so as to facilitate the storage and storage of the two, and improve the overall flexibility of the device.

Embodiment 3

[0016] Example 3: Such as figure 1 As shown, the detection console 3 is provided with a monitoring display screen 11 and a pressure regulating display screen 12, the monitoring display screen 11 is connected to the pressure monitoring circuit 6, and the pressure regulating display screen 12 is connected to the pressure pipeline 8; by displaying The screens 11 and 12 are convenient for the operator to visually judge the pressure situation in the pressure vessel, find the difference in time, and make judgment conveniently.

Abstract

The invention discloses a detection apparatus of leakage of a pressure container. The apparatus comprises a fixation platform, a vacuum pressure pump and a control detection bench. The vacuum pressure pump is connected with the control detection bench through a connecting pipeline, a pressure pipeline is arranged above the control detection bench, a pressure monitoring line is arranged beside the control detection bench, the connecting pipeline is connected with the air inlet of the pressure container through the pressure pipeline, the top portion of the pressure monitoring line is provided with a sealed end, the pressure monitoring line is connected with the air outlet of the pressure container through the sealed end, and the top portion of the sealed end is provided with a pressure inductor. The apparatus provided by the invention is simple in structure, through comparing pressure generated when the vacuum pressure pump of the apparatus works with actual pressure in the pressure container, minimal change of pressure in a housing can be conveniently observed, the apparatus itself can perform pressurizing or vacuum-pumping operation on the inside of the housing, and whether the pressure container leaks can be determined through multiple modes; and the operation is flexible, the dismounting and carrying are convenient, and the practical effect is good.
