Description
Technical field
The utility model belongs to fuel tank quality inspection device technical field, and in particular to a kind of automotive oil tank air-leakage test dress
It sets.
Background technique
Fuel tank, i.e. fuel oil storage facility require corrosion resistance high.In double work pressure, it is at least in gauge pressure
It should be sealed when 0.03MPa.The excess pressure of generation must through hole or safety valve voluntarily depressurize.Negotiation of bends, tilted road surface or
Fuel oil should not be flowed out from the sealing cover or pressure equaliser of liquid feeding when being impacted.Fuel tank must come out engine installation,
In order to avoid lighting fuel oil when there is traffic accident.
Utility model content
The purpose of this utility model is to provide a kind of automotive oil tank air-tightness detection devices, overcome the prior art not
Foot, is arranged several independent sensing chamber, and detection interior is placed into after in the detection process sealing fuel tank, opens corresponding electricity
Magnet valve is evacuated sensing chamber, and records the pressure after pumping, and pressure is observed in waiting again after a certain period of time, if pressure is without change
Then fuel tank is air tight for change, and the fuel tank gas leakage if pressure changes utilizes the difference of external pressure after pumping and fuel tank internal pressure
Fuel tank air-tightness is detected, it is clean practical and easy to detect, it is at low cost.
To solve the above problems, technical solution adopted in the utility model is as follows:
A kind of automotive oil tank air-tightness detection device, including supporting leg and detection case, the detection case are rectangular parallelepiped structure,
And inside is divided into several independent sensing chamber by several partitions, is equipped with sealing cover, the inspection above the sensing chamber
It is equipped with air extractor and controller outside measuring tank, each sensing chamber bottom is equipped with exhaust tube, on each exhaust tube
It is equipped with solenoid valve, the exhaust tube is connect with air extractor air inlet by delivery main, is all provided on each sealing cover
There are independent pressure gauge and independent button switch, the button switch is connect and corresponded with solenoid valve by controller.
Further, the controller is PLC controller.
Further, the controller is connected with power plug by conducting wire.
Further, the sealing cover is equipped with vent valve.
Further, the vent valve is Manual air-release valves, and the Manual air-release valves are equipped with rotary switch.
Further, the sealing cover is equipped with handle.
Compared with prior art, having the advantages that
A kind of automotive oil tank air-tightness detection device described in the utility model, is arranged several independent sensing chamber, is examining
It is indoor that it is placed into detection after sealing fuel tank during survey, opens corresponding solenoid valve and sensing chamber is evacuated, and record pumping
Pressure is observed in pressure after gas, waiting again after a certain period of time, and fuel tank is air tight if pressure is unchanged, if pressure changes
Fuel tank gas leakage detects fuel tank air-tightness using external pressure after pumping and the difference of fuel tank internal pressure, clean practical, and examines
It is convenient to survey, at low cost.
