Description
Technical field
The present invention relates to a kind of union joint, being used for of using in a kind of fuel pump oil return press tune device, jet pump and
The easily changeable adaptor of Stud connection.
Background technology
Electric fuel punp mainly provides the fuel oil of certain pressure for automobile fuel injection system, and pump core gives combustion by pipeline
Oil system fuel feeding detects feedback pressure by system pressure, and oil return adjusts device, jet pump to return to oil through pressure after electromotor consumption
Chi Zhong.Adjust in pressure and the noise that stud causes with fall low-pressure adjusting device jet oil spout is installed between device and jet pump.At present, stud
Rear end and injector special frock extruding assembling, the dismounting inconvenience of device is adjusted at two ends respectively with pressure.In use send out
Existing, the phenomenons such as stud blocking often occur, causes car load to occur abnormal.But stud dismounting is inconvenient, clean inconvenience, nothing
Dismounting secondary assembly performance, the most only selects to change fuel oil pump assembly, causes waste and high expensive.
Summary of the invention
The technical problem to be solved be to provide a kind of for press adjust device, jet pump and Stud connection the most more
The adaptor changed, can realize the light replacing of stud.
Technical scheme is as follows: a kind of for pressing tune device, jet pump and the easily changeable adaptor of Stud connection,
It is characterized in that: include that stud installs pipe, described stud is installed the outer position near the upper end mouth of pipe of pipe and is provided with annular boss, institute
Stating stud and install the top overcoat nylon pipe joint of pipe, described nylon pipe joint includes the major diameter set being sequentially connected with from top to bottom
Pipeline section and minor diameter transitional tubing piece, described major diameter casing section is enclosed within outside annular boss, and described stud installs the upper end of pipe
The mouth of pipe reaches in the bottom of minor diameter transitional tubing piece, described major diameter casing section is provided with two sections along its circumferentially extending arc
Spacing hole, two sections of described arc-shaped limit holes are oppositely arranged, and two supporting legs of " u "-shaped limited location snap ring insert two sections of arc-shaped limit holes respectively
In, described " u "-shaped limited location snap ring contacts with annular boss and carries out spacing to it, and it is right that the outside in described arc-shaped limit hole is provided with
" u "-shaped limited location snap ring carries out spacing limited block.
Use such scheme, stud is installed pipe and is connected with jet pump, during assembling, nylon pipe joint is taken off, by stud
Being arranged on stud to install in pipe, then be enclosed within by nylon pipe joint outside stud installation pipe, then inserted by limited location snap ring, nylon tube connects
The other end of head receives the rear end of pressure regulator, thus easily can change in the case of not damaging pressure regulator and jet pump
With cleaning stud.Avoid once the situation changing assembly that breaks down.
In such scheme: described stud is provided with in installing pipe and stud is carried out spacing limit rib.
In such scheme: described stud is installed pipe annular and is evenly equipped with three limit ribs.
Preferred: described limit rib is positioned at the lower section of annular boss.So, when stud loads in stud installation pipe, have
It is beneficial to spacing to stud.
In such scheme: the top of described minor diameter transitional tubing piece is also associated with bending pipe, described minor diameter is excessively managed
The upper end mouth of pipe of section is closed, the centrage of described bending pipe and the central axis of minor diameter transitional tubing piece.So, bending pipe is even
Being connected on pressure regulator, the pipe that this band is turned is more convenient for installing than straight tube.
Beneficial effect: what the employing present invention designed is used for pressing tune device, jet pump and the easily changeable adaptor of Stud connection
Can realize in the case of not damaging jet pump and pressure regulator, take off stud easily, be convenient for changing stud or stud is carried out
Clean, it is to avoid cause unnecessary waste, reduce use cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is outline drawing.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
