Abstract
The utility model discloses a device using an airtight limit sample to detect an airtight leakage meter. The device comprises a detection platform, an airtight leakage detector, an air inlet end airtight jig, an air exhaust end airtight jig, a detection air inlet airtight jig and an airtight limit sample. The air inlet end airtight jig and the air exhaust end airtight jig are fixed on the detection platform through bolts. The airtight leakage detector is arranged on one side of the detection platform. The airtight leakage detector, the air inlet end airtight jig, the air exhaust end airtight jig and the detection air inlet airtight jig are connected through an air detection wiring and an electrical signal control wiring. The airtight limit sample is formed by manually making a small hole at the set position of an airtight detection sample. The airtight limit sample is simultaneously clamped and fixed with the air inlet end airtight jig, the air exhaust end airtight jig and the detection air inlet airtight jig.
Description
Technical field
The utility model relates to the automobile exhaust system technical field, particularly relates to using the device that airtight limit exemplar detects airtight leakage instrument on the automobile exhaust system.
Background technology
Airtight leakage detector is used widely in automobile exhaust system, can special requirement be arranged to the leakage rate of part on the drawing, though can use airtight standard specimen air-tight apparatus to be carried out the demarcation and the detection of airtight leakage standard value in every month; But because of air-tight apparatus physical construction generation problem; Make instrument detecting not go out true leakage rate, the phenomenon that can not correctly report to the police often has generation, therefore; Produce in the product in reality, need a kind of device that detects airtight leakage detector physical construction to separate
The determine problem of above-mentioned existence.
The utility model content
The technical matters that the utility model will solve provides a kind ofly in daily production, stops because of physical construction changes, and the airtight limit exemplar of the application that causes airtight leakage detector correctly not report to the police detects the device of airtight leakage instrument.
The technical scheme that adopts is:
Use the device that airtight limit exemplar detects airtight leakage instrument, comprise detection platform, airtight leakage detector, the airtight anchor clamps of inlet end, the airtight anchor clamps of exhaust end, the airtight anchor clamps of detected gas import, airtight limit exemplar.The airtight anchor clamps of described inlet end, the airtight anchor clamps of exhaust end, the airtight anchor clamps of detected gas import are arranged on the detection platform, and wherein the airtight anchor clamps of inlet end, the airtight anchor clamps of exhaust end are through being bolted on the detection platform.Said airtight leakage detector is installed in a side of detection platform, and airtight leakage detector, the airtight anchor clamps of inlet end, the airtight anchor clamps of exhaust end and the airtight anchor clamps of detected gas import are connected with electric signal control wiring through the gas detection wiring.Said airtight limit exemplar is made up of at the artificial aperture of making of desired location airtight detection exemplar, and airtight limit exemplar is fixed in the airtight anchor clamps of inlet end, the airtight anchor clamps of exhaust end and the airtight clamp of detected gas import simultaneously.
Above-mentioned airtight limit exemplar is formulated the different airtight limit exemplars that guarantee that its leakage rate is reported to the police instrument according to the leakage rate that the airtight detection exemplar of difference requires.
The utility model operating limit exemplar detects air-tight apparatus whether mechanical problem takes place: when the operating limit exemplar detects leakage rate, leak instrument for reporting to the police, show that mechanical fault does not take place instrument on duty, can produce.In daily production, stop because of physical construction changes, cause airtight leakage detector correctly not report to the police.

Fig. 2 is the airtight limit exemplar synoptic diagram of the utility model.
Embodiment
Use the device that airtight limit exemplar detects airtight leakage instrument, comprise the airtight anchor clamps of the airtight anchor clamps of the airtight anchor clamps of detection platform 5, airtight leakage detector 1, inlet end 2, exhaust end 3, detected gas import 4, airtight limit exemplar 6.The airtight anchor clamps of the airtight anchor clamps of described inlet end 2, exhaust end 3, the airtight anchor clamps 4 of detected gas import are arranged on the detection platform 5, and wherein the airtight anchor clamps of inlet end 2, the airtight anchor clamps 3 of exhaust end are through being bolted on the detection platform 5.Said airtight leakage detector 1 is installed in a side of detection platform 5, and the airtight anchor clamps of airtight leakage detector 1, inlet end 2, the airtight anchor clamps 3 of exhaust end are connected through gas detection wiring and electric signal control wiring with the airtight anchor clamps 4 of detected gas import.Said airtight limit exemplar 6 is formulated the different airtight limit exemplars that guarantee that its leakage rate is reported to the police instrument according to the leakage rate that the airtight detection exemplar of difference requires.Airtight limit exemplar 6 is to constitute at the artificial aperture 8 of making of the desired location of airtight detection exemplar 7; Airtight limit exemplar 6 is fixedly clamped at the airtight anchor clamps of inlet end 2, the airtight anchor clamps 3 of exhaust end and the airtight anchor clamps 4 of detected gas import simultaneously, constitutes and uses the device that airtight limit exemplar detects airtight leakage instrument.
Principle of work
To the leakage rate that requires on the different detail drawings, formulate different airtight limit exemplars, (limit exemplar leakage value should be less than the leakage value of drawing permission in order to add tight requirement for the leakage value of limit exemplar; And should set airtight tester reports to the police when limit exemplar is detected), (class of opening remodels before beginning at every turn; Behind the equipment downtime); Detect air-tight apparatus with limit exemplar, the result who limit exemplar is detected when air-tight apparatus is for NG and when reporting to the police, on duty can production.Limit exemplar margin tolerance is X ± 3 б, and wherein X is the mean value that 30 limit exemplars of measurement numerical value is drawn; б is a standard deviation; X ± 3 б can not surpass the theory setting value.In factory, should there be corresponding limit exemplar lay down location and limit exemplar should paint red convenient and finished product pieces O.K. differentiation.
