Description
Technical field
The utility model belongs to shipbuilding technical field, more particularly to a kind of more suction gun helium mass spectrum leak detection devices.
Background technology
Tightness test is that the comprehensive of LNG ship liquid goods containment system manufacture and assembly quality is checked, and is to whole cargo hold area
The last key link examined together, be guarantee LNG ship shipping safety that the integrality in domain is done.In whole tightness test process
In, wherein helium mass spectrum leak detection is the most cumbersome, also the most key, and helium mass spectrum leak detection is checking outside comprehensively by helium mass spectrometer leak detector
The close implementations of point and all weld seams of primary and secondary film.And helium mass spectrum leak detection is divided into automatic detection and two kinds of detection manually, detection manually
It is responsible for the tightness test of the special areas such as craft weld seam, angular region and invar pipe.In existing detection manually, usually one is pushed away
Car, a helium mass spectrometer leak detector and a suction gun form a test unit, and this detection mode needs two operating personnel same
Shi Zuoye, a people are responsible for pushing and pulling trolley and monitor helium mass spectrometer leak detector, and another human hand held suction gun is detected weld seam.This inspection
Survey mode waste of manpower, and less efficient, the serious efficiency for restricting shipbuilding.
The content of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of more suction gun helium mass spectrum leak detection dresses
Put, in the apparatus, one helium mass spectrometer leak detector of multiple suction guns collocation, can be carried out at the same time multiple spot leak detection, leak detection is efficient.
The purpose of this utility model is achieved through the following technical solutions：
A kind of more suction gun helium mass spectrum leak detection devices, including helium mass spectrometer leak detector, inserted type quick coupling, multi-way pipe fitting and two
A above suction gun, one end of the inserted type quick coupling are stretched in the air inlet of helium mass spectrometer leak detector, and the plug-in type is fast
The other end of quick coupling is connected with multi-way pipe fitting, and the suction gun is connected by hose respectively with multi-way pipe fitting.
One connector of multi-way pipe fitting is connected with inserted type quick coupling, remaining connector of multi-way pipe fitting respectively with suction gun
It is connected by hose, the gas that each suction gun absorbs is entered by hose, multi-way pipe fitting and inserted type quick coupling successively
In helium mass spectrometer leak detector.
Preferably, the multi-way pipe fitting is tee pipe fitting, and the suction gun has two.
Preferably, the multi-way pipe fitting is four-way pipe fitting, and the suction gun has three.
Preferably, the hose is rubber hose.
Preferably, the multi-way pipe fitting is copper or stainless steel.
Shipyard is built in more and borders on the river, borders on the sea etc., these local air humiditys are larger, and multi-way pipe fitting is copper or stainless steel
Material, can effectively prevent multi-way pipe fitting from the situations such as corrosion occur.
The beneficial effects of the utility model are：A helium mass spectrometer leak detector is combined with multiple suction guns, Ke Yizhi in the device
Hold multiple operating personnel while hand-held suction gun carries out multiple spot leak detection, leak detection efficiency greatly improves.Helium mass spectrometer leak detector higher price,
And suction gun price is relatively low, a helium mass spectrometer leak detector coordinates multiple suction guns in the utility model, with a conventional helium mass spectrum leak detection
Leak hunting method of the instrument with unification suction gun is compared, and the technical solution of the utility model has saved fund, reduce shipbuilding into
This.

Embodiment
The more suction gun helium mass spectrum leak detection devices of the utility model are done into one with specific case study on implementation below in conjunction with the accompanying drawings
Elaborating for step, in the hope of being more fully apparent from expresses the architectural feature and concrete application of the utility model, but cannot be with this
To limit the scope of protection of the utility model.
Embodiment 1：As shown in Figure 1, a kind of more suction gun helium mass spectrum leak detection devices, including helium mass spectrometer leak detector 1, plug-in type are fast
Quick coupling 3, multi-way pipe fitting 4 and two or more suction gun 2, one end of the inserted type quick coupling 2 stretch to helium mass spectrometer leak detector 1
Air inlet in, the other end of the inserted type quick coupling 3 is connected with multi-way pipe fitting 4, the suction gun 2 and multi-way pipe fitting 4
It is connected respectively by hose 5.
In the present embodiment, the multi-way pipe fitting 4 is tee pipe fitting, and the tee pipe fitting is stainless steel, the suction gun 2
There are two, two suction guns 2 are connected with tee pipe fitting by hose 5 respectively；The hose 5 is rubber hose, the suction gun 2 with
Hose 5 corresponds.
In operation, an operating personnel promote the trolley for placing helium mass spectrometer leak detector 1 and monitor helium mass spectrometer leak detector 1
Data, two other operating personnel hold a suction gun 2 and carry out leak detection operation, carried when leakage occurs in helium mass spectrometer leak detector 1 respectively
When showing, stopping next suction gun 2, another suction gun 2 continues operation, and whether observation helium mass spectrometer leak detector 1 also has leakage prompting, if
1 No leakage of helium mass spectrometer leak detector is prompted, then is leaked at the detection of the suction gun 2 to stop, if helium mass spectrometer leak detector 1 has leakage
Prompting, then leak at the detection of the suction gun 2 of continuation operation.
