Abstract
This utility model belongs to airtight detection technique field, and disclose a kind of gas inspection leakage tester for carrying out steady testing under open condition to workpiece, including source of the gas, air accumulator, closure cylinder, hygral equilibrium tank is gentle inspects leakage instrument, and source of the gas connects the hygral equilibrium tank and the air accumulator respectively；Air accumulator connects the closure cylinder；Hygral equilibrium tank is inspected the signal piping on Lou instrument by connecting tube and the gas and is connected, and the hygral equilibrium tank is connected with factory feeding pneumatic by air inlet pipe；Gas to be inspected and be provided with frock on Lou instrument.This utility model is solved under open power house environment, and it is inconsistent with workpiece temperature that winter seasonal epidemic pathogens inspect Lou instrument temperature, and causes that detection data is untrue, wrong report situation.After the balance of temperature, workpiece and gas are inspected heat exchange Lou between instrument and are reduced, then reduce gas and inspect contraction that pipeline in Lou instrument, sealing member caused due to temperature change or expand impact to testing result.
Description
Technical field
This utility model belongs to airtight detection technique field, examines leakage tester more particularly, to a kind of gas.
Background technology
As gas examines leakage tester under open power house environment, during winter, the temperature of workpiece is often than in gas inspection leakage tester
The temperature of the compressed air for being used is low, and result of such temperature difference necessarily to detecting causes unstable, so as to there is product
Detection data is untrue, wrong report situation.The workpiece sensing that there will be leakage is possible to into No leakage workpiece, goes to product stream
Lower operation, so can cause serious mass loss, and the fame to enterprise causes irremediable injury to user.
Conventional way is directly to be passed into after instrument using work source of the gas, is inflated in workpiece；Or through air accumulator
After enter back into.The temperature of the former source of the gas is completely it cannot be guaranteed that consistent with workpiece.And the latter is as air accumulator is through moving component
Tolerance consume after, then workpiece is inflated, in this when source of the gas, the gas of different temperatures will be brought in workpiece, institute
Impact of the temperature difference to testing result can be caused with both.
Utility model content
For the disadvantages described above or Improvement requirement of prior art, this utility model provides one kind under open condition
The gas inspection leakage tester of steady testing is carried out to workpiece, to reduce the risk that detection data wrong report occurs in product, product is greatly increased
Reliability when detecting in the winter time.
For achieving the above object, according to this utility model, there is provided a kind of for carrying out surely to workpiece under open condition
The gas inspection leakage tester of location survey examination, it is characterised in that including source of the gas, air accumulator, closure cylinder, hygral equilibrium tank is gentle inspects Lou
Instrument, wherein,
The source of the gas connects the hygral equilibrium tank and the air accumulator respectively；
The air accumulator connects the closure cylinder, and the closure cylinder is used for the inner chamber of closed work piece；
The hygral equilibrium tank is inspected the signal piping on Lou instrument by connecting tube and the gas and is connected, and the temperature
Compensator is connected with factory feeding pneumatic by air inlet pipe；
The gas is inspected and is provided with Lou instrument for fixing the frock of workpiece.
The preferred connecting tube is flexible pipe.
In general, by the contemplated above technical scheme of this utility model compared with prior art, can obtain down
Row beneficial effect：
This utility model is solved under open power house environment, and winter seasonal epidemic pathogens are inspected Lou instrument temperature and differed with workpiece temperature
Cause, and cause that detection data is untrue, wrong report situation.After the balance of temperature, the heat that workpiece and gas are inspected Lou between instrument is handed over
Reduction is changed, is then reduced gas and is inspected the contraction or expand to testing result that pipeline in Lou instrument, sealing member caused due to temperature change
Impact.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain
This utility model, is not used to limit this utility model.Additionally, institute in this utility model disclosed below each embodiment
As long as the technical characteristic being related to does not constitute conflict each other and can just be mutually combined.
With reference to Fig. 1, a kind of gas inspection leakage tester for carrying out steady testing under open condition to workpiece, including source of the gas,
Air accumulator 1, closure cylinder, hygral equilibrium tank 5 is gentle inspects Lou instrument 2, wherein,
The source of the gas connects the hygral equilibrium tank 5 and the air accumulator 1 respectively；
The air accumulator 1 connects the closure cylinder, and the closure cylinder is used for the inner chamber of closed work piece；
The hygral equilibrium tank 5 is inspected the signal piping on Lou instrument 2 by connecting tube 3 and the gas and is connected, and described
Hygral equilibrium tank 5 is connected with factory feeding pneumatic by air inlet pipe 6；Preferably, the connecting tube 3 is flexible pipe；
The gas is inspected and is provided with Lou instrument 2 for fixing the frock 4 of workpiece.
Hygral equilibrium gas tank is different from air accumulator 1, and the effect of air accumulator 1 is to reduce pressure oscillation energy accumulation.And temperature
Relief holder inspects Lou instrument peripheral temperature for gas for the gas temperature balance for carrying out factory's feeding pneumatic, i.e., when normally using
When, gas temperature is basically identical with workpiece temperature.When gas is entered in pipeline to be checked, workpiece cavity, all of heat
Exchange will be little.
Gas is set and inspects on Lou instrument 2 for example parameter such as inflationtime, equilibration time, to coordinate hygral equilibrium tank 5 to enter enforcement
With Lou realize steady testing during winter under open environment so as to reaching gas and inspecting.
The purpose of this utility model is realized by following technology：
A. artificial placement is detected workpiece and inspects in the detecting tool 4 in Lou instrument 2 to gas；
B. gas inspects the Lou whether qualified No leakage of 2 automatic detection workpiece of instrument, by hygral equilibrium tank 5 during winter, will be with which
Gas temperature in the gas circuit of connection and the temperature realization balance of workpiece, inspect leakage instrument due to examined workpiece temperature and gas to reduce
Between impact of the temperature difference to testing result；After the balance of temperature, the heat exchange that workpiece and gas are inspected Lou between instrument subtracts
It is few, then reduce gas and inspect the contraction or expand to testing result that pipeline in Lou instrument, sealing member caused due to temperature change
Affect.
C., gas is set and inspects parameters in Lou instrument 2, with the effect of cooperation hygral equilibrium tank 5 of making up the difference, span of control is 5
℃-10℃。
As it will be easily appreciated by one skilled in the art that preferred embodiment of the present utility model is the foregoing is only, not
To limit this utility model, all any modifications made within spirit of the present utility model and principle, equivalent and change
Enter, should be included within protection domain of the present utility model.
