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:
The invention belongs to leak detection suction gun structure-design technique field in the simple leak hunting technology.
Background technology:
The leak detection suction gun is one of indispensable parts of recipe leak locator.When hunting leak with mass-spectrometer leak detector, if adopt the aeration leak detection, the leak detection suction gun can have, it is connected on the leak locator, regulate suitable gas flow, guarantee that instrument is in normal leak detection state, tested container fills with the helium of suitable pressure or the combination gas of helium.During leak detection, if container has leakage, then the helium in the container leaks by small opening, can be sucked in the mass-spectrometer leak detector by suction gun along with air, and it is big that the indication of instrument just becomes, and can judge position and its leak rate size of small opening thus.Stamping container is implemented simple leak detection, can improve the quality of products greatly, the requirement to the high pressure vessel leak detection in recent years constantly increases, and simple rifle leakage technology is applied in many technical fields.The mass-spectrometer leak detector demand constantly increased in recent years, and the leak detection suction gun also is put into the row of indispensable parts.
At present, the quick leak-checking suction gun of domestic use is import, and it is small and exquisite, reliable, but price is more expensive, and domestic this product also forms series, the product that has employing needle-valve principle design, the big difficult processing of its volume.The suction gun mouth and the suction gun inner diameter of common suction gun are smaller, and relatively the gas flow that sucks is few, and along with the growth of suction gun flexible pipe, the leak detection required time obviously increases, and causes the decrease in efficiency of hunting leak.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of existing leak detection suction gun, and the speedy suction gun device of a kind of simple in structure, response time piece, long service life is provided.
The present invention is achieved by the following technical solutions:
Speedy suction gun device is characterized in that: include valve seat, have through hole in the valve seat, the through hole two ends are chewed with the micro air pump air intake opening by flexible pipe and suction respectively and are connected, and atmosphere is led in the gas outlet of micro air pump; There is leak hunting aperture to be connected on the described valve seat, gas separator is installed on the leak hunting aperture with described through hole.
Described speedy suction gun device is characterized in that: described leak hunting aperture is communicated with the leak detection mouth of mass-spectrometer leak detector; Described gas separator is the helium separation vessel.
Described suction is chewed the end handle is installed.
The suction of being told is chewed filtrator is housed, to prevent that suction gun from stopping up and maintenance suction gun cleaning.
Described speedy suction gun has been installed small-sized micro air pump, matches with gas circuit, has increased the soakage and the flow velocity that has improved gas of gas:
Described speedy suction gun has been installed the helium separation vessel, can cross impurity such as leaching life and some big molecular gass:
The speedy suction gun of telling has been installed the suction gun valve seat, and the design by its inner air path has improved the soakage of gas to external world.
Advantage of the present invention is:
Suction of the present invention is chewed with inner diameter bigger, can avoid common suction gun decrease in efficiency problem, has improved the efficient of leak detection greatly, has saved the time of leak detection.Impurity such as grey life and big molecular gas have effectively been filtered in the use of helium separation vessel, have guaranteed the vacuum tightness requirement of helium mass spectrometer leak detector and have avoided pollution, have increased the serviceable life of instrument.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Embodiment:
Speedy suction gun device includes valve seat 2, has through hole in the valve seat 2, and the through hole two ends are connected with to inhale by flexible pipe 5 respectively chews 4 and micro air pump 3 air intake openings; Have leak hunting aperture 6 on the valve seat 2 and be connected, helium separation vessel 7 is installed on the leak hunting aperture 6 with through hole.Leak hunting aperture 6 is communicated with the leak detection mouth of mass-spectrometer leak detector.Suction is chewed 4 ends handle 1 is installed.
Leak hunting aperture 6 is connected with the leak detection mouth of helium mass spectrometer leak detector, micro air pump 3 energized make its work then, pressing helium mass spectrometer leak detector " leak detection " key again makes it be in the leak detection state, at this moment extraneous a large amount of gases are chewed 4 inner air paths that enter into valve seat 2 by suction, enter micro air pump air intake opening 8 according to the most of gas of certain ratio, be discharged to the external environment from micro air pump gas outlet 9 at last.Small part gas mainly is that helium enters leak hunting aperture 6 by helium separation vessel 7, and finally this part gas enters helium mass spectrometer leak detector and carries out mass spectrophotometry.
