Abstract

The invention provides a simply-coated accumulative air tightness detection device. The device comprises a seal membrane, lute, an adapting piece, a helium mass spectrometer leak detector and a helium source, wherein the lute is a formed lute part and comprises a forming ring and an outer mold, the forming ring is an annular structure made of an elastic material, and the forming ring is wrapped in the outer mold made of vacuum lute in a sleeved and adhesive mode. The invention further provides a method for detecting the air tightness of a workpiece to be detected by means of the device. The formed lute part is adopted to replace bulk lute to seal the seal membrane and the edge of the detection area of the workpiece to be detected. Compared with bulk lute, the formed lute part has the remarkable advantages that by the adoption of the structure that the forming ring is wrapped in the outer mold, no leakage point can be generated, and excellent sealing performance is guaranteed; after leakage detection is finished, the formed lute part can be peeled off together with the seal membrane, time and labor are saved, repeated use can be realized, and then cost is reduced.

Description

technical field [0001] The invention relates to a simple coating accumulation type air tightness detection device, and also relates to a simple coating accumulation type air tightness detection method. Background technique [0002] Airtight detection technology is widely used, and the commonly used detection methods are ranked according to the detection accuracy: helium mass spectrometry detection method, hydrogen detection method, differential pressure detection method, water immersion gas collection method, etc. Among them, helium mass spectrometry detection method is characterized by high sensitivity, reliability and Reliable, repeatable, and fast response and clearance times. Helium mass spectrometry was developed in the 1940s, and its application and development to this day have achieved brilliant achievements. There are many leak detection methods of helium mass spectrometry, which can be divided into two types according to the measurement purpose of the inspected par...
