Description

The fixing tool of fuel pipe and the air tightness detection equipment of fuel hose
Technical field
The present invention relates to the technical field of sebific duct detection, the gas of fixing tool and fuel hose more particularly, to fuel pipe Close property detection device.
Background technology
Fuel pipe detection is typically detected using water inspection equipment in automobile industry at present, i.e., using water as medium, by fuel pipe It is put into the container for filling water, fuel hose one end blocks by hand, and the other end is passed through the air of certain pressure, during one section of pressurize Between, see whether that bubble is spilt from fuel pipe, judged whether fuel pipe has leakage with this.
Prior art more falls behind, only whether to there is bubble the basis for estimation whether leaked for fuel pipe occur, by All artificially participated in these judgements, the tiny bubble occurred for those fuel pipe micro-leakages be easy to it is ignored, And also it is easy to error in judgement occur when operator is in fatigue state for a long time, cause the product outflow of leakage.
The content of the invention
It is an object of the invention to provide the sebific duct end of fuel hose closure frock, snap joint fixing tool and air-tightness Detection device, there is error in judgement to solve long-time manual operation present in prior art, cause the product outflow of leakage Technical problem.
The present invention provides a kind of fixing tool of fuel pipe, including the closure frock of sebific duct end and is connected with fuel pipe fast The fixing tool of quick coupling;
The closure frock of the sebific duct end includes:Sleeve, annular groove is provided with the madial wall of described sleeve one end, separately One end is connected with air inlet pipe;
Sealing ring is provided with the annular groove;
Also include block rubber, the block rubber is cylinder;
The sealing ring is enclosed on the lateral wall of the block rubber;
The one end of the block rubber away from the air inlet pipe has cylindrical groove, for being socketed with fuel hose;
The fixing tool of the snap joint includes opponent's part, and one end of opponent's part has cylindrical cavity, Neng Gou Snap joint makes cylindrical cavity be tightly connected with snap joint when inserting the cylindrical cavity;The other end of opponent's part is set There is hollow cylindrical channel, be connected for passing through air inlet pipe with snap joint;
The fixing tool of the snap joint also includes handle and claw, one end of the handle and one end of the claw It is fixedly connected, the connection angle of the handle and the claw is more than 90 degree and is less than 180;
The other end of the claw has a spacing block set, the axis of the protrusion direction of the spacing block set towards cylindrical cavity It is and perpendicular;
The junction of the handle and the claw is provided with lug, and projection is provided with the lateral wall of opponent's part, Coupling bar is rotatably connected through the projection with the lug.
Further, the lug is two, is be arranged in parallel, in addition to torsionspring, the spring sheet of the torsionspring For body between the lug, one end of the torsionspring is parallel with handle, and the other end is parallel with the lateral wall of opponent's part;Institute Coupling bar is stated through projection, a lug, the spring eye of torsionspring and another lug and is fixed.
The present invention provides a kind of air tightness detection equipment of fuel hose, includes the fixing tool of fuel pipe, in addition to enter Device of air, the outlet side of inlet duct are connected with the first branch and the second branch, and the first branch is another with closure frock sleeve End is tightly connected, and the second branch and the other end of opponent's part are tightly connected.
Further, the inlet duct includes source of the gas processing unit;The source of the gas processing unit include moisture filter, Oil stain filter and limit valve, three are connected by pipeline.
Further, the outlet side connection booster pump of the source of the gas processing unit, for compressed gas source.
