Technical field
This utility model relates to repairing facility of a kind of Aviation Fuel system, particularly relates to a kind of airtight test of signal indicator auxiliary
Assistant engineer has.
Background technology
Airborne signal device is generally mounted to aircraft fuel oil fuel tank internal, the oil level signal of survey aircraft fuel quantity, signal
Device is required to check the air-tightness of signal indicator when repairing or check.When signal indicator air-tightness lost efficacy, in fuel tanker
Kerosene can at signal indicator inefficacy seepage kerosene, threaten flight safety.
Signal indicator model and kind are more, and principle is identical with structure, are all made up of signal sense device and cable, cable
Inside signal indicator, directly experience position draw, draw interface section and use sealant pouring and sealing, be integral type structure after encapsulating, it is impossible to
Twice decomposition.The cable length of signal indicator is generally 3m～5m.Currently without the air-tightness of signal indicator individually being tried
The equipment tested or instrument.When checking signal indicator air-tightness now, need signal indicator to be arranged on fuel tank internal, overall to fuel tank
Carry out air seal test, judged the performance of signal indicator by the air-tightness of fuel tank.So in each signal indicator air-tight test
Time, the air-tightness of signal indicator can only be judged by the overall air-tightness of fuel tank, fuel tanker is bulky, internally installed product
Product and pipeline quantity are more, when the overall airtight inefficacy of fuel tank, it is impossible to quick and precisely judging the product that specifically lost efficacy, it is right to take
The method that the product of fuel tank internal and pipeline are changed one by one is got rid of, and which adds workload, and individual signals device is repeatedly
Dismounting need to additionally increase the working time about 5 working days, and need to waste aerial kerosene 600kg.
Utility model content
This utility model embodiment technical problem to be solved is, for not having the instrument can be with individual inspiration signal indicator
Air-tightness, and fuel tank entirety is carried out the problem that air seal test adds economy and time cost, it is proposed that Yi Zhongxin
Number device airtight test aid.
In order to solve above-mentioned technical problem, this utility model embodiment provides a kind of signal indicator airtight test auxiliary work
Tool, this signal indicator airtight test aid includes: clamp base, is provided with sealing lid, seals lid and clamp base bottom it
Be internally formed an airtight inner-cavity structure of hollow, clamp base away from seal lid one end on offer and inner space
Upper shed, seals and covers the under shed offered with inner space；Gas source interface, is connected with the upper shed of clamp base；It is spigot joint,
It is arranged at sealing to cover away from the side of clamp base, is connected with under shed.
Wherein, the sidewall bottom sealing lid stretches out formation protuberance, seals lid outer and flushes with protuberance outer.
Wherein, protuberance offers groove on the side seal lid, is provided with O grommet type seal circle in groove.
Wherein, the protuberance of clamp base and sealing lid are fixed nut by hexagonal and are removably connected.
Wherein, hexagonal is fixed and is provided with installation pad between the nut head of nut and protuberance.
Wherein, spigot joint one end away from sealing lid being provided with the second nut, the cable of signal indicator is introduced into inner chamber and letter
Number device insert spigot joint after fixed by the second nut.
Implement this utility model embodiment, have the advantages that signal indicator of the present utility model airtight test auxiliary
Instrument can solve signal indicator repairing with the air-tightness of individual inspiration signal indicator or test can not individually carry out air seal test
Problem, not only increases work efficiency, and has saved economic and time cost.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the side-looking structural representation of the signal indicator airtight test aid that this utility model provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
This utility model provides a kind of signal indicator airtight test aid, and referring to Fig. 1, Fig. 1 is this utility model
The side-looking structural representation of the signal indicator airtight test aid provided.This signal indicator airtight test aid includes: folder
Tool base 10, sealing lid 11, inner chamber 12, upper shed 13, under shed 14, O grommet type seal circle 15, hexagonal are fixed nut 16, are installed
Pad 17, protuberance 18, groove 19, gas source interface 20, spigot joint 30 and second nut 31.
The bottom of clamp base 10 is provided with sealing lid 11, and the sidewall bottom sealing lid 11 stretches out formation protuberance
18, seal lid 11 outers and flush with protuberance 18 outer.Protuberance 18 offers groove 19 on the side seal lid 11, recessed
O grommet type seal circle 15 is installed in groove 19.The protuberance 18 of clamp base 10 and sealing lid 11 fix nut 16 by hexagonal can
Dismounting connects, and hexagonal is fixed and is provided with installation pad 17 between the nut head of nut 16 and protuberance 18.Seal lid 11 and fixture
