Abstract
The invention discloses a mode for connecting high-pressure overflow oil return tubes and avoiding interference. According to the mode, nylon tubes and connectors are arranged. The mode for connecting the high-pressure overflow oil return tubes and avoiding interference is characterized in that each nylon tube is connected with the corresponding connector, and the nylon tubes are connected with the connectors in the mode that each nylon tube is connected with the connector next to the connector closest to the nylon tube rather than in the mode that the nylon tubes are connected with all the connectors in sequence from one end to the other end to form a string. The nylon tubes are connected with the connectors in series. The connection section of each nylon tube is a coiler. In this way, the interference between an oil pump and each nylon tube located below a center line of the corresponding connector of a curved oil tube is avoided conveniently. According to the mode for connecting the high-pressure overflow oil return tubes and avoiding interference, the structure is simple, production and machining are convenient, the reliability is high, arrangement is convenient, durability is achieved, and no blind angle of a connector angle exists.
Description
Technical field
The invention belongs to engine fuel pipe road technique field, especially one be used for evading interfere high pressure overflow
Flow back to oil pipe Placement.
Background technique
At present, engine high pressure overflows back oil pipe and generally uses metal pipe or moulding nylon tube.As use metal tube: 1. cost of production price is high, need to oil pipe and joint be welded, be annealed, tubing such as electroplates at the rust preventing, complex process.2. metal tube hardness is large, installs and is difficult to regulate, and inconvenience is installed, and adjusting exists erection stress after installing, and quality of product exists hidden danger.3. each joint sealing face of oil pipe will remain on same plane guarantee sealing, and difficulty of processing is large.
As use moulding nylon tube: the minimum bending radius that 1. moulding nylon tube requires is large, the bending radius of fractional value is difficult to manufacture, and easily giving a discount, cause cannot smooth and easy oil return; While 2. adopting the bending radius of large numerical value, easily interfere with other parts of motor, be difficult to layout, cause overflowing back oil pipe and can not be arranged in the extreme lower position of high-pressure oil pipe.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect of prior art, taked a kind of simple and ingenious structure, convenient installation adjustment, high pressure with low cost to overflow back oil pipe arrangement, solving existing high pressure, to overflow back oil pipe price high, installs, arranges inconvenient problem.
Technological scheme solution of the present invention is such: one is used for evading interferes high pressure to overflow back oil pipe Placement, comprises nylon tube, joint, it is characterized in that nylon tube (1) is connected with joint (2).
Joint (2) joint (2) of being separated by is connected with nylon tube (1).
Nylon tube (1) is to be connected in series mode with joint (2).
Nylon tube (1) is that the pipeline section being connected in series is that main drive tube is little with joint (2).
The pipeline section of nylon tube (1) serial connection joint (2) is coiler
Nylon tube (1) linkage section does not have blind angle.
Nylon tube (1) is only used headtotail, and one section, one section of company joins, and first paragraph pipe tail joint (2) connects the connection of second segment pipe tail joint (2).
Nylon tube (1) need not in the middle of be situated between take over serial fashion connect.
Nylon tube (1) locates to install an oil meter of measuring oil pressure oil mass.
Nylon tube (1) is plastic pipe, at plastic pipe, has snakeskin aluminum metal flexible pipe outward.
Advantage of the present invention is: on a bulb, be welded with multiple joints, flexible pipe connects the adjacent bulb that can stagger.Simple in structure, production and processing is convenient.Reliability is high, does not have erection stress.Oil pipe requirements of installation space is little, is convenient to mounting arrangements, with low cost, durable in use.
Accompanying drawing explanation
It is such that structure of the present invention forms:
fig. 1 is that the present invention is a kind of for evading the main schematic diagram of looking of structure connection of interfering high pressure to overflow back oil pipe Placement.
Fig. 2 is that the present invention is a kind of for evading the schematic diagram of the structural bending nylon tube moulding layout of interfering high pressure to overflow back oil pipe Placement.
In Fig. 1～Fig. 2, nylon tube (1), joint (2).
embodiment
below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 3, with reference to the structure of Fig. 1～Fig. 2, nylon tube (1) connects end section dislocation and takes over, but the end connector (2) of the Article 1 pipe of nylon tube (1) connects Article 2 pipe end connector (2), like this one connects next mode, and does not need to be situated between and to connect mode with intervalve.
Embodiment 4, with reference to the structure of Fig. 1～Fig. 2, and plastic pipe for nylon tube (1), but comprise snakeskin hose layer at plastic pipe skin.At protection return tube, maintain outside soft activity like this, also can strengthen Rigidity and strength, also can oil leakage prevention.
Embodiment 5, and with reference to Fig. 1～Fig. 2, nylon tube (1) is connected in series in situation by joint (2) end to end, locates to install more than one fuel tap, the oil circuit oil mass of segmentation control oil transportation size at joint (2).
Embodiment 6, with reference to Fig. 1～Fig. 2, nylon tube (1) serial connection or and the mode that connects connect, at nylon tube (1), locate to install an oil meter and survey oil pressure or oil mass.
Finally it should be noted that: the present invention and and unrestricted technological scheme described in the invention: therefore, although this specification has been described in detail the present invention with reference to each above-mentioned embodiment, but, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the present invention: and all do not depart from technological scheme and the improvement thereof of the spirit and scope of the present invention.It all should be encompassed in claim scope of the present invention.
