Description
Technical field
The utility model is related to fuel vehicle fuel tank detection field more particularly to a kind of utilization air pressure detection fuel vehicle fuel tank are close
The detection device of envelope property.
Background technology
Fuel vehicle fuel tank is one of important component of oil-burning machine, and leakproofness is the most important performance of fuel vehicle fuel tank.
After vehicle production process intermediate fuel oil vehicle fuel tank must carry out 100% sealing propertytest, determine its leakproofness qualification afterwards
It can be mounted on fuel vehicle, so the detection of automotive oil tank leakproofness is that a labor intensity is larger in vehicle production process
Key post.At present, existing fuel vehicle fuel tank device for detecting sealability is used to immerse fuel oil sump in water tank more and examined
It surveys, while gases at high pressure is added in fuel tank is detected, by artificially observing whether the fuel vehicle fuel tank being immersed in water has gas
Bubble overflows, so as to judge to be detected the leakproofness of fuel tank；Although so detection can comply with standard, there is following defects：
Buoyancy is larger after fuel tank is filled with air, it is therefore desirable to multiple reviewer's cooperative detections, due to manual operation, it is understood that there may be part
The situation that region is not immersed in the water or depth is inadequate, the problem of causing testing result inaccurate, while also need to a pond and make
Occupied space into fuel tank sealing propertytest system is big, and mobility is poor；It is more convenient how fuel vehicle fuel tank sealing propertytest,
Detection efficiency is improved, becomes insoluble technical barrier for a long time.
In view of the foregoing, a kind of detection device using air pressure detection fuel vehicle fuel tank leakproofness is now developed.
Utility model content
The purpose of this utility model is to overcome deficiencies of the prior art, provide a kind of utilization air pressure and detect fuel vehicle
The detection device of fuel tank leakproofness detects fuel vehicle fuel tank leakproofness using air pressure, makes fuel vehicle fuel tank sealing propertytest more square
Just, the number of reviewer is greatly reduced, improves detection efficiency, improves the accuracy of detection.
The utility model to achieve these goals, adopts the following technical scheme that：It is a kind of to utilize air pressure detection fuel vehicle oil
The detection device of case leakproofness, be by：Power supply box, power supply, contactor, the time relay, solenoid valve, gas tank, air pressure electric contact
Pressure gauge, three-way valve, air inlet pipe, air outlet pipe, connecting tube are formed；Gas tank one side sets power supply box, and the top in power supply box is set
Put power supply, power supply lower section sets contactor and the time relay, the company of setting between the gas outlet of gas tank and the air inlet of solenoid valve
It takes over, the upper end of three-way valve is docked with air pressure electro connecting pressure gauge lower end, the air inlet of three-way valve and the outlet of solenoid valve
Air inlet pipe is set between mouthful, the gas outlet of three-way valve sets air outlet pipe, solenoid valve respectively with power supply, contactor, time relay
Conducting wire between device is set, conducting wire between power supply and contactor is set, conducting wire is set between air pressure electro connecting pressure gauge and contactor.
The beneficial effects of the utility model are：When in use, startup power supply switchs, and contactor opens solenoid valve, makes gas tank
In gases at high pressure enter fuel tank through connecting tube, the time relay set time in, shown on air pressure electro connecting pressure gauge
Numerical value reach the numerical value specified, illustrate fuel tank leakproofness reach standard requirement, air pressure electro connecting pressure gauge control contactor
Solenoid valve is powered off, closes solenoid valve；In the time set in the time relay, the numerical value that is shown on air pressure electro connecting pressure gauge
The numerical value not up to specified illustrates that the leakproofness of fuel tank is not up to standard requirement；The utility model detects fuel vehicle using air pressure
Fuel tank leakproofness is more convenient fuel vehicle fuel tank sealing propertytest, greatly reduces the number of reviewer, improves detection
Efficiency improves the accuracy of detection, and the utility model is simple in sturcture, ingenious in design, safe to use, is suitble to popularity should
With.
