Abstract
The utility model relates to a diesel engine high-pressure fuel conduit for a bus, which comprises a high-pressure fuel conduit and two fastening nuts respectively arranged on the fuel injection pump end and the fuel injector end of the high-pressure fuel conduit. The structure of the utility model is characterized in that the upper half section of the high-pressure fuel conduit is provided with a rubber pipe; the upper end of the rubber pipe is sheathed with the fastening nut on the fuel conduit end and is tightly clamped to be fixed through a pipe clamp; a gap is arranged between the high-pressure fuel conduit and the inner wall of the rubber pipe. Because the utility model is provided with the protection of the rubber pipe, although a failure occurs to the high-pressure fuel pipe, the leaky fuel can not be sprayed to a high-temperature machine body and an exhaust pipe, but is collected together to flow to one end of an oil pump through the rubber pipe. Thus, the utility model has the advantages that the occurrence of serious accidents of fire, etc. can be avoided, and the safety of running of the bus is improved.
Description
Technical field
The utility model relates to the oil supplying device technical field of diesel engine, particularly relates to a kind of diesel engine high-pressure oil pipe.
Background technique
High-pressure oil pipe one end of diesel engine connects Injection Pump, and the other end connects oil sprayer.In order to satisfy Europe II emission request, domestic diesel engine generally adopts P7100 Injection Pump and P type oil nozzle at present, to improve jet pressure.The high-pressure oil pipe of existing diesel all is to make with the seamless cold drawing steel tube of single wall, because the increase of oil pressure and the aggravation of vibrations during diesel engine work, cause the leakage of oil of high-pressure oil pipe cracking easily, on if diesel oil sprays high temperature bodies such as falling outlet pipe from the oil pipe cracking, causing body possibly catches fire, lead to serious accident, particularly bring serious hidden danger to passenger vehicle.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of simple in structure, diesel engine high-pressure oil pipe that Security is good is provided.
The utility model passenger vehicle is improvement on existing diesel high-pressure oil pipe basis with the diesel engine high-pressure oil pipe, Injection Pump end tightening nut and oil sprayer end tightening nut that it comprises high-pressure oil pipe equally and is contained in the high-pressure oil pipe two ends, its special structural feature is that the upper semisection at high-pressure oil pipe is equipped with rubber pipe, the upper end of rubber pipe is sleeved on the oil sprayer end tightening nut, and is fixedly clamped by pipe clamp.
Aforesaid passenger vehicle diesel engine high-pressure oil pipe, the internal diameter of its rubber pipe promptly have the gap between high-pressure oil pipe and rubber pipe inwall greater than the external diameter of high-pressure oil pipe.
Owing to the utlity model has the protection of rubber pipe, even high-pressure oil pipe lost efficacy, the fuel oil that leaks can splash yet to the hot body of height, flow to oil pump one end but can collect by rubber pipe, prevented that simultaneously the fuel oil that leaks from flowing to outlet pipe one side, thereby can avoid the loss that causes that serious accidents such as fire cause, improve the travel safety of passenger vehicle.
Description of drawings
Fig. 1 is a plan view of the present utility model, shows its overall structure.
Embodiment
The accompanying drawing illustrated embodiment, the utility model comprises an existing high-pressure oil pipe, be that it has high-pressure oil pipe 1 equally and is contained in the Injection Pump end tightening nut 2 and the oil sprayer end tightening nut 3 at high-pressure oil pipe 1 two ends, upper semisection at high-pressure oil pipe 3 has installed an end rubber pipe 4 again additional, the upper end of rubber pipe 4 is sleeved on the oil sprayer end tightening nut 3, and is fixedly clamped by pipe clamp 5.The internal diameter of this rubber pipe 4 promptly has the gap between high-pressure oil pipe 1 and rubber pipe 4 inwalls greater than the external diameter of high-pressure oil pipe 1, thereby the fuel oil that spills is flowed out.
Claims (2)
1, a kind of passenger vehicle diesel engine high-pressure oil pipe, comprise high-pressure oil pipe (1) and be contained in the Injection Pump end tightening nut (2) and the oil sprayer end tightening nut (3) at high-pressure oil pipe (1) two ends, it is characterized in that: the upper semisection at high-pressure oil pipe (3) is equipped with rubber pipe (4), the upper end of rubber pipe (4) is sleeved on the oil sprayer end tightening nut (3), and is fixedly clamped by pipe clamp (5).
2, passenger vehicle according to claim 1 diesel engine high-pressure oil pipe is characterized in that the external diameter of the internal diameter of rubber pipe (4) greater than high-pressure oil pipe (1), promptly has the gap between high-pressure oil pipe (1) and rubber pipe (4) inwall.
