Helium mass spectrometer leak detector capable of realizing high-pressure detection

Abstract

The invention discloses a helium mass spectrometer leak detector capable of realizing high-pressure detection, and relates to the technical field of high-pressure detection devices. The helium mass spectrometer leak detector comprises a leak detector body, and the surface of the leak detector body is connected with a connecting pipe. A mounting pipe is arranged on the surface of the connecting pipe; a reset mechanism is arranged in the mounting pipe; the reset mechanism is used for sealing the mounting pipe; and the surface of the mounting pipe is connected with a detection pipe; the surface of the leak detector body is connected with a mounting seat. By arranging the mounting pipe, the sealing plate, the reset spring and the fixing rod, the device can solve the technical problems that when the leak detector does not need to perform detection, a connecting port is always in an exposed environment, so that impurities contained in external air may enter the interior, and unnecessary influence is caused on the internal structure of equipment, and in addition, the detection pipe is only connected by using a hoop, so that the detection pipe is possibly loosened, air leakage is caused during high-pressure detection, and the detection result is inaccurate.

Description

technical field [0001] The invention relates to the technical field of high-voltage detection devices, in particular to a helium mass spectrometer leak detector capable of high-pressure detection. Background technique [0002] The helium mass spectrometer leak detector uses helium as the leak detection gas, and the gas analyzer detects the helium to detect the mass spectrometer. The helium mass spectrometry leak detection technology is an indispensable technology in the field of vacuum leak detection. Due to the leak detection High efficiency, simple and easy to operate, has been widely used in resistance furnace leak detection. [0003] At present, common helium mass spectrometer leak detectors use clamps to connect the detection tube to the helium mass spectrometer leak detector. When no detection is required, the connection port is often in an exposed environment, resulting in impurities contained in the external gas. It may enter the interior and cause unnecessary impac...
