Speedy suction gun device

Abstract

The invention discloses a speedy suction gun device. The invention is characterized in that the speedy suction gun device comprises a valve seat, the valve seat is internally provided with a through hole, two ends of the through hole are connected with suckers and the gas inlet of a miniature gas pump by hoses, the gas outlet of the miniature gas pump communicates with the atmosphere; the valve seat is provided with leakage detection holes to communicate with the through hole, and a gas separator is arranged on the leakage detection holes. The invention can avoid the problem of slow response time of a common suction gun, shortens response time and improves leakage detection efficiency. The adoption of the helium separator effectively filters such impurities as dust, macromolecular gases and the like, ensures volume degree requirement of the helium mass spectrum leak detector, avoids contamination ad prolongs service life of the detector. And meanwhile the invention combined with the mass spectrum leak detector can be widely applied to leakage detection of various aeration equipments and instruments.

Description

Technical field: [0001] The invention belongs to the technical field of leak detection sniffer structure design in simple leak detection technology. Background technique: [0002] The leak detector sniffer is one of the essential parts of the recipe leak detector. When using a mass spectrometer leak detector to detect leaks, if the leak detection method is used, the leak detection sniffer must be connected to the leak detector and adjust the appropriate gas flow to ensure that the instrument is in the normal leak detection state. The container is filled with helium or a mixture of helium at an appropriate pressure. During leak detection, if there is a leak in the container, the helium gas in the container leaks out through the leak hole. As the air is sucked into the mass spectrometer leak detector by the sniffer, the indicator of the instrument becomes larger, and the leak can be judged. The location and its leakage rate. The implementation of simple leak detection of stampin...

AI Technical Summary

Problems solved by technology

[0003] At present, the rapid leak detection suction gun used in China is imported. It is small and reliable, but the price is relatively expensive. This product has not yet formed a series in China. Some products are designed using the needle valve principle, which is large in size and difficult to process.

The inner diameter of the sniffer nozzle and the sniffer hose of the ordinary sniffer gun is relatively small, and the amount of gas sucked is relatively small, and with the increase of the sniffer hose, the time required for leak detection increases significantly, resulting in a decrease in leak detection efficiency
