Abstract

The invention discloses a device for rapidly detecting the sealing performance of an object at low temperature, which comprises a substrate. The top of the substrate is provided with a ventilation groove. A sample to be detected is covered above the ventilation groove. Sealing washers are arranged between the bottom surface of the sample to be detected and the top of the substrate. The top of the sample to be detected is provided with a pressing tool. The sealing washer is arranged between the top surface of the sample to be detected and the pressing tool. The bottom of the pressing tool is provided with the ventilation groove which is communicated with the top of the sample to be detected. The ventilation groove at the top of the substrate is communicated with a gas molecule mass spectrometer leak detector. The ventilation groove at the bottom of the pressing tool is communicated with a gas source. The device for rapidly detecting the sealing performance of the object at the low temperature can detect and obtain the sealing performance of product components and parts sealed by rubber at the low temperature.

Description

technical field [0001] The invention relates to the technical field of airtightness detection, in particular to a device for quickly detecting the airtightness of an object at low temperature. Background technique [0002] At present, many industrial products have high requirements on the sealing performance of parts, and the sealing performance of some key parts directly affects the quality and service life of the product, so the sealing performance of the parts is effectively tested during the production process appears to be particularly important. [0003] Rubber seals are used in the sealing of many product parts. Various rubbers will have an ideal sealing effect when the corresponding compression ratio is reached. In the production process, the sealing performance of such parts needs to be checked. detection. [0004] Because the product parts sometimes need to be used under low temperature conditions, the rubber will shrink when it is cold, which will change the sea...
