Description
Technical field
The utility model is related to the interface arrangement that a kind of motor vehicle fuel pipe and valve seat or connector etc. are tightly connected, especially
It is related to the motor vehicle fuel interface tube that a kind of Double-fuel switches multiple-way valve.
Background technology
Turn with to vehicle economy and alternative fuel economy, the concern of the feature of environmental protection, automaker and Market for refitting
To more economical, Cleaning Equipment, to improve efficiency and energy-conserving and environment-protective, so alternative fuel or dual-purpose fuel or pluralities of fuel
Effectively use, it is necessary to the distinct configuration of traditional fuel engine associated components, wherein for changing during two kinds of fuel charges, realizing
Reliably switch between two kinds of motor vehicle fuels, the Double-fuel switching multiple-way valve that former fuel leaves are few during switching.And lead to more
Valve will be connected with two kinds of even three kinds of different fuel pipes, set more and led on the valve seat that multiple-way valve is utilized in connection of the prior art
Rail mounting hole, is sleeved on guide rail in the guide rail of the built-in hard of guide rail mounting hole, then by cartridge or fuel hose, and such as China is real
" it is exactly the guide rail that sets in Double-fuel switching multiple-way valve 201510088541.9 ", in the appearance of guide rail with new patent application
Face is provided with multiple conical surface bulge loops, by the way that on guide rail, springy connection Hose Jacket is utilized into the reverse friction of conical surface bulge loop
The characteristics of power is big, realizes and connects the anticreep of flexible pipe and guide rail, is tightly connected.Although this connected mode can be realized and is tightly connected,
But there is following defect：1st, special Pipe installing instrument is needed；2nd, in connection installation process, the breakage of fuel is easily caused to be made
Into potential safety hazard, 3, conical surface bulge loop in the higher engine room of temperature, connection flexible pipe follows the string or expanded, and causes sealing not
Sternly, escape of fuel etc., reduces service life and causes security incident；It can not realize and connect quick change soon.
The content of the invention
The purpose of this utility model, which is to provide, a kind of can connect the motor vehicle fuel interface tube of quick change soon, it is not necessary to complicated pipeline
Installation tool, simplifies mounting process, reduces the cartridge breakage occurred in installation process, or because the high temperature in engine room draws
Play leakage fuel after the expansion of fuel and cause potential safety hazard, install convenient, realization is tightly connected, not escape of fuel, and energy can after connection
Connection status is locked by ground.
The utility model proposes a kind of motor vehicle fuel interface tube, including it is counterbore in valve seat, taper bolt, external
Pipe, cartridge, sealing ring, counterbore include circular cone hole section, cylinder hole section, counterbore and the oil inlet passage insertion in valve seat, counterbore bottom
Portion sets an annular mounting platform, and sealing ring is on mounting platform, and extension tube attached outer end is sleeved on fuel tube outer surface, fuel
Pipe the inner extends the sealing ring for extending and being pushed against on mounting platform more than mounting platform, extension tube attached the inner, the inner tube wall of extension tube attached
On be provided with least one axially split groove；Taper bolt front portion is conical ring.
Preferably, the sealing ring is single O-ring seal or double O-ring seals, and described pair of O-ring seals are O-shaped by two
Sealing ring and the annulus composition between two sealing rings.
External bore is adapted with cartridge outside dimension.
It is threaded cylindrical ring in the middle part of taper bolt, taper bolt rear portion is the nut for protruding from counterbore setting.
The beneficial effects of the utility model are:During installation, taper bolt is screwed into, the small conical ring of outer imperial palace squeeze into it is heavy
During the circular cone hole section in hole, extension tube attached the inner is set to be tightened up pressure and shunk, extension tube attached axially splits groove under external force into extension tube attached
Wall is tightened at the cartridge of the heart, and the inner 1-3 bars of extension tube attached axially split groove closure, the banding cartridge such as clamping jaw, to cartridge
Outer wall formation grip, prevents cartridge from being come off because of fuel pressure, extension tube attached outer end is not slotted；The cylindrical ring of taper bolt is provided with outer
Screw thread, degree is screwed into by adjusting taper bolt in counterbore, can adjust the propulsion depth of conical ring, and then adjust extension tube attached
The inner banding degree to socket seat pipe, and reliably can be tightly connected state by lock-bit；The handling of this interface are quick and easy, install
When cartridge need to only be inserted after, put extension tube attached, then by taper bolt；Two O-ring seals of double O-ring seals rise
To dual-seal function, prevent escape of fuel；External bore is adapted with cartridge outside dimension, in tight fit, but in external force
In the presence of both relative can slide, during taper bolt is screwed into, extension tube attached be in the case where the forward thrust of conical ring drives to
Preceding movement tendency is slightly promoted, and can further push against sealing ring, is drawn in while groove is split in its axial direction, promptly cartridge；Taper spiral shell
The nut of bolt protrudes from counterbore setting, is easily installed, and be able to can just be installed by hand or using common wrench；Cartridge is extended more than peace
Assembling platform, is easy to extension tube attached to put forth effort to firmly grasp, prevent leakage.In a word, this interface can connect quick change soon, and install convenient realizes that sealing connects
Connect, it is ensured that not escape of fuel, connection status can be reliably locked after connection.
