Description

The fast connection interface of motor vehicle fuel pipe
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 fast connection interface of motor vehicle fuel pipe 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 follow the string or it is swollen rise, cause 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 fast connection interface of motor vehicle fuel pipe of quick change soon, it is not necessary to complicated Pipe installing instrument, simplifies mounting process, reduces the cartridge breakage occurred in installation process, or because of the height in engine room Temperature, which causes, reveals fuel after the expansion of fuel, and causes potential safety hazard, and install convenient, realization is tightly connected, not escape of fuel, connection After can reliably lock connection status.
The utility model proposes a kind of fast connection interface of motor vehicle fuel pipe, including counterbore in valve seat, hollow bolt, combustion Expects pipe, sealing ring, counterbore and the oil inlet passage insertion in valve seat, the mounting platform for annular of counterbore base, sealing ring are located at On mounting platform, cartridge the inner is extended or more than mounting platform, and at least one is provided with the inner tube wall of hollow bolt axially Split groove;Hollow bolt is provided with external screw thread, and counterbore is provided with internal thread, during hollow bolt is screwable into counterbore, hollow spiral shell Bolt tightens up cooperation with counterbore for progressive.
Preferably, when being installed in place, the axial direction of hollow bolt is split groove closure or part under the effect of counterbore circumferential pressure and closed Close, and hollow bolt inner face pushes against sealing ring.
The sealing ring is single O-ring seal or double O-ring seals, described pair of O-ring seals by two O-ring seals and Annulus composition between two sealing rings.
The hole section or all tapered taper holes, correspondingly hollow bolt is partly or entirely Taper Pipe.
The counterbore is cylindrical hole, and hollow bolt is cylindrical tube, and spiral shell in the gradually taper of depth is provided with from outside to inside in counterbore Line, is correspondingly provided with from outside to inside the gradually external screw thread of depth in cylindrical tube.
Cartridge passes through the centre bore of hollow bolt, and cartridge the inner is extended in the oil inlet passage in valve seat, oil inlet passage A locating platform is inside set to limit cartridge inner face position.
Hollow bolt is provided with nut, and nut is located at outside counterbore.
The beneficial effects of the utility model are:During installation, taper bolt is screwed into, hollow bolt is progressive receipts with counterbore Tight fit, when being installed in place, the axial direction of hollow bolt is split groove closure or part under the effect of counterbore circumferential pressure and closed, such as clamping jaw As banding cartridge, to fuel pipe outer wall formation grip, prevent cartridge from being come off because of fuel pressure, hollow bolt serves propulsion Promptly, automatic lock-bit double action is positioned.The handling of this interface are quick and easy, after only cartridge need to be inserted during installation, put outer Adapter, then by taper bolt;And hollow bolt inner face pushes against sealing ring, make sealing ring in compressive deformation, counterbore wall, Tight seal between hollow bolt inner face, cartridge, two O-ring seals of double O-ring seals play dual-seal function, Prevent escape of fuel;The counterbore is partly or entirely slightly has the taper hole of taper, and hollow bolt is correspondingly part or all of taper Smaller Taper Pipe, can just make make in hollow bolt progradation under the squeezing action of counterbore, and groove receipts are split in its inner axial direction Hold together;The counterbore is cylindrical hole, and hollow bolt is cylindrical tube, and the gradually taper internal thread of depth is provided with from outside to inside in counterbore, Gradually deep external screw thread from outside to inside is correspondingly provided with cylindrical tube, the difficulty of processing of this mode is low, can also push away hollow bolt Groove gathering is split in inner axial direction during entering;Nut is easily installed, with hand or spanner with regard to that can tighten installation located at heavy outer.In a word, This interface can connect quick change soon, and install convenient, realization is tightly connected, it is ensured that not escape of fuel, and connection shape can be reliably locked after connection State, make between two kinds of fuel rails of automobile, between guide rail and switching valve etc. a variety of occasions reliable seamless connection, it is not necessary to it is complicated Pipe installing instrument, simplify mounting process, reduce the cartridge occurred in installation process damaged, it is to avoid because in engine room High temperature cause the expansion of cartridge to cause fuel losses and cause potential safety hazard so that two kinds of fuel such as methanol, gasoline, can It is engine feed with sharing an injector and dependable performance..
