Description
Technical field
This utility model relates to a kind of helium vacuum leak detection device.
Background technology
Helium mass spectrometer leak detector is gas industry vocabulary of terms, such as the Chinese patent of Application No. 200820161470.6, makees probe gas with helium, carries out, with gas analyser detection helium, the mass spectrograph hunted leak.The background noise of helium is low, and molecular weight and the coefficient of viscosity are little, thus easily by small opening and easily spreads；Helium system noble gas, not etching apparatus, therefore conventional helium makees probe gas.Being sprayed onto by this gas on the tested container being connected to gas analyser, if container has small opening, then analyser has reacted, thus understands small opening place.
Existing helium vacuum leak detection device, is simply used for vacuum leakage detection aspect by helium mass spectral analysis, does not considers on-the-spot specific works needs, and helium can not persistently be supplied, and extensive work is for repeatedly transporting helium in a small amount.The Stress control difficulty when concrete leakage detection position spraying helium, reduces the accuracy of the magnitude that helium is analyzed.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency present in prior art, and the helium vacuum leak detection device of a kind of reasonable in design is provided, reduce the labor intensity of staff, improve work efficiency and the accuracy of vacuum leakage detection result, reduce the human cost of vacuum leakage detection work.
The technical scheme in the invention for solving the above technical problem is: a kind of helium vacuum leak detection device, including helium mass spectrometer and helium feeding mechanism, it is characterised in that: described helium feeding mechanism includes that helium pressure store tank, air relief valve, Pressure gauge, regulation valve, effusion meter, flexible pipe, spray gun, expansion link and nitrogen go out pipe；Nitrogen goes out pipe one end and is connected with the outlet of helium pressure store tank, and the other end is with hose connection；Air relief valve, Pressure gauge, regulation valve, effusion meter are sequentially arranged at nitrogen and go out on pipe；Spray gun is arranged on expansion link, and with hose connection.
The bottom of helium pressure store tank described in the utility model is provided with universal wheel.
Helium pressure store tank described in the utility model is cylindrical tank, a diameter of 20cm, and height is 40cm.
Flexible pipe rubber described in the utility model is made.
This utility model compared with prior art, has the following advantages and effect: reasonable in design, reduces the labor intensity of staff, improves work efficiency and the accuracy of vacuum leakage detection result, reduces the human cost of vacuum leakage detection work；Could dictate that use pressure and the flow of helium vacuum leakage detection, it is stipulated that spraying rate (every meter per second), operating process standardization so that the result data of test can contrast demonstration at the standard conditions.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following example are that this utility model is not limited to following example to explanation of the present utility model.
See Fig. 1, this utility model embodiment includes helium mass spectrometer 1 and helium feeding mechanism, and helium feeding mechanism includes that helium pressure store tank 2, air relief valve 3, Pressure gauge 4, regulation valve 5, effusion meter 6, flexible pipe 7, spray gun 8, expansion link 9 and nitrogen go out pipe 10.
Nitrogen goes out pipe 10 one end and is connected with the outlet of helium pressure store tank 2, and the other end is connected with flexible pipe 7.
Air relief valve 3, Pressure gauge 4, regulation valve 5, effusion meter 6 are sequentially arranged at nitrogen and go out on pipe 10.
Spray gun 8 is arranged on expansion link 9, and is connected with flexible pipe 7.
The bottom of helium pressure store tank 2 is provided with universal wheel.Helium pressure store tank 2 small in volume, is suitable for two adult's carryings (including local stair activity).Helium pressure store tank 2 is cylindrical tank, a diameter of 20cm, and height is 40cm, used by the enough vacuum leakage detections of amount of internal reservoir helium.
Air relief valve 3 can be effectively isolated helium in helium pressure store tank 2, prevents to outward leakage.
Pressure gauge 4, regulation valve 5, effusion meter 6 regulate helium supply pressure, stably improve helium mass spectrometer 1 precision of analysis, use pressure and the flow of helium vacuum leakage detection is provided in rule of operation, operating process standardization so that the result data of test can contrast at the standard conditions.
Expansion link 9 controls spray gun 8 and moves, and it is aluminum alloy material, is successively set in together and can stretch, total 4 meters long, and the interior fixing end of joint can be freely rotatable for spherical connection.
Flexible pipe 7 facilitates operator that helium sprays to each device of generating set and the corner of equipment, it is to avoid the work of vacuum leakage detection retains dead angle because of technological means reason.Flexible pipe 7 can slide along expansion link 9.Flexible pipe 7 is made with rubber.
Open air relief valve 3 and spray gun 8, adjust the definite value that regulation valve 5 makes the pressure on Pressure gauge 4 and the flow on effusion meter 6 specify in code.With spray gun 8 at the spraying rate spraying helium needing the position of spraying to specify according to code, at the discharge duct outlets of vacuum pump, helium mass spectrometer 1 detects that helium can find leak source, the size of result of the test magnitude can react the size of leak source.The result data of test can contrast demonstration at the standard conditions.In process of the test, helium pressure store tank 2 is placed on same floor height and can all be detected by the suspection leak source of this layer.Different floor heights can use elevator vehicle.Helium can persistently be supplied and avoid a large amount of manpower and the most repeatedly transport the labor intensity that in a small amount helium is increased, and saves plenty of time cost.Helium pressure flow spray time stablize the precision that improve time result.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, the shape of its parts and components, be named title etc. can be different, and the above content described in this specification is only to this utility model structure example explanation.
