Abstract

The present invention relates to a kind of fuel tanker pressure tester, belong to aircraft manufacturing technical field.It includes that a technique lid matched with fuel tanker lid, described technique lid edge and junction are for sealing structure;Be provided through logical pressure pipe and lower logical pressure pipe at the middle part of described technique lid, described logical pressure pipe and lower logical pressure pipe are connected with a change-over valve, and Pressure gauge is connected with the outer spout of upper logical pressure pipe and lower logical pressure pipe by sealing nut.The present invention solves the fuel tanker interior pressure problem that can not accurately read internal pressure when doing that oil is closely knit to be tested, it is simple to reviewer can check whether fuel tank has leak point efficiently.

Description

A kind of fuel tanker pressure tester
Technical field
The present invention relates to a kind of fuel tanker pressure tester, belong to aircraft manufacturing technical field.
Background technology
During the production of aircraft is assembled, the sealing in fuel tank district is particularly significant, the best direct relation of sealing Aircraft safety and performance, therefore the fuel tank district of aircraft not only needs the air-tightness doing airtight experiment to ensure fuel tank, but also Permeability to be done experiment ensures the oil-tightness of fuel tank, and this patent is to do the simple convenient pressure measurement of oil pressure test for tightness one in fuel tanker district Device.The permeability experiment doing fuel tank district needs to inject certain oil mass and certain air pressure in fuel tank, then keeps a timing Between see whether air pressure changes, in the past do close test when, be the reading on the upward pressure dial plate of the instruction carriage by input air pressure Number detects the force value in fuel tank, because fuel tank internal has certain oil pressure during oil pressure test for tightness, it is impossible to reflect fuel tank really Atmospheric pressure value, and need upper lower aerofoil all to carry out oil pressure experiment to integral wing tank, so devising this fuel tanker On the pressure of inside during pressure tester realization detection fuel tank oil pressure test for tightness and integral wing tank during lower aerofoil oil pressure test for tightness not Needing to dismantle lid, after upset, straightway testing just can pressure measurement.
Summary of the invention
In order to overcome drawbacks described above, it is an object of the invention to provide a kind of fuel tanker pressure tester, can be used to true The real device reading inside aircraft fuel tanks pressure ensures the sealing of product more accurately, thus is further ensured that the height of product Quality, and instrument is installed and used simple and convenient, it is simple to and operative, after upset, experiment need not dismantle lid, thus improves Production efficiency.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of fuel tanker pressure tester, it includes a technique lid matched with fuel tanker lid, described technique Lid edge and junction are for sealing structure;
Logical pressure pipe and lower logical pressure pipe, described logical pressure pipe and lower logical pressure it is provided through at the middle part of described technique lid Guan Yuyi change-over valve connects, and Pressure gauge is connected with the outer spout of upper logical pressure pipe and lower logical pressure pipe by sealing nut.
When checking the oil-tightness of fuel tank lower half structure, i.e. lid up time, then the switch of change-over valve have a position to B position rotates, and when after fuel tank overturns, lid is downward, then the switch of change-over valve has b position to rotate back to a position.
The inner spout of described logical pressure pipe and lower logical pressure pipe is at fuel tank internal, and the inner spout of lower logical pressure pipe is under fuel tank Wall;Upper logical pressure pipe inner spout is near the upper wall of fuel tank.
The measurement of one responsible fuel tank upwards state of two logical pressure pipes, another one is responsible for the measurement of the downward state of fuel tank, So latter two logical pressure pipe is connected with a change-over valve.Change-over valve is responsible for switching the shape that two logical pressure pipes are connected with Pressure gauge State, it is ensured that logical pressure pipe the most in need is connected with Pressure gauge, and the pressure in fuel tank is shown by Pressure gauge.
Beneficial effects of the present invention:
The present invention solve fuel tanker do oil closely knit test time interior pressure can not accurately read asking of internal pressure Topic, it is simple to reviewer can check whether fuel tank has leak point efficiently.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the pressure tester operating diagram up of the present invention;
Fig. 3 is that the pressure tester of the present invention is at lower work schematic diagram.
Detailed description of the invention
1,2,3 describe the present invention below in conjunction with the accompanying drawings:
A kind of fuel tanker pressure tester, it includes a technique lid 2 matched with fuel tanker lid, described technique Lid 2 edge and junction are for sealing structure;
Be provided through logical pressure pipe 3 and lower logical pressure pipe 1 at the middle part of described technique lid 2, described logical pressure pipe 3 and under Logical pressure pipe 1 is connected with a change-over valve 4, and Pressure gauge 6 is by sealing nut 5 and upper logical pressure pipe 3 and the outer spout of lower logical pressure pipe 1 Connect.
When checking the oil-tightness of fuel tank lower half structure, i.e. lid up time, then the switch of change-over valve 4 has a position Rotating to b position, when after fuel tank overturns, lid is downward, then the switch of change-over valve 4 has b position to rotate back to a position Put.
The inner spout of described logical pressure pipe 3 and lower logical pressure pipe 1 is at fuel tank internal, and the inner spout of lower logical pressure pipe 1 is near fuel tank Lower wall;Upper logical pressure pipe 3 inner spout is near the upper wall of fuel tank.
During use, the sealing cover on fuel tanker is disassembled, the technique lid that band in the present invention seals structure is existed Being installed by bolt on corresponding mouth frame, technique lid is installed after putting in place and is connected also with the joint of change-over valve by pressure tester Carry out sealing, after checking installation qualification, just can do that fuel tank oil is closely knit to be tested, when oil-tightness (the i.e. mouth of inspection fuel tank lower half structure Lid is up) time, then the switch of change-over valve has a position to rotate (as shown in Figure 2) to b position, when fuel tank carries out overturning deutostoma When covering downward, then the switch of change-over valve has b position to rotate back to a position (as shown in Figure 3), so fuel tank internal in experiment Directly from Pressure gauge, pressure reading can get information about whether tank internal pressure meets requirement of experiment, reach requirement After numerical value, the time pressure value constant i.e. explanation fuel tank sealing through regulation is good, if numerical value diminishes, just explanation fuel tank seals Defective, need again to seal.Therefore the present invention can allow easily reviewer check fuel tank seal the best, it is ensured that The efficient production of aircraft.
