Abstract
The utility model discloses a splashing preventing fuel guide pipe which comprises a fuel pipe and a connector. A splashing preventing mechanism is mounted in the connector. The splashing preventing mechanism comprises inner threads and an isolation piece. The inner threads are formed in the inner wall of the connector. The isolation piece is disposed at the connection of the connector and the fuel pipe. A fuel outlet and an adjusting hole are formed in the isolation piece. One side, close to the fuel pipe, of the fuel outlet is provided with a turned-up edge. The isolation piece between the connector and the fuel pipe can slow down fuel flowing fast, allow the fuel to enter a fuel pump through the fuel outlet, and prevent the fuel from entering a fuel inlet along the inner wall of the fuel pipe. Due to the fact that one side, close to the fuel pipe, of the fuel outlet is provided with the turned-up edge, the turned-up edge is a protrusion arranged at the edge of the fuel outlet, the fuel is prevented from flowing out from the edge of the fuel outlet, the fuel can slowly form an oblique angle by the self-inertia, and the fuel column formed in a certain distance after flowing through the fuel outlet diminishes gradually and cannot splash and spread outwardly.
Description
Technical field
The utility model relates to fuel delivery equipment, specifically refers to a kind of antispray oil guide pipe.
Background technique
The function of fuel oil supply system is to supply in time the needed fuel oil of fuel oil under various operating modes to motor, and fuel oil supply system is mainly comprised of fuel tank, electric fuel punp, fuel filter, return tube, fuel pressure regulator, hydro pulse damper, oil sprayer, transport pipe, cold-start injector etc.Fuel oil is pumped from fuel tank by fuel pump, by fuel filter elimination impurity, through oil pulse damper, deliver to fuel pressure regulator, under the effect of fuel pressure regulator, make the difference of oil pressure and suction tude internal air pressure keep constant, then by transport pipe, provided and delivered to each oil sprayer and cold-start injector.Oil sprayer, according to the instruction of ECU, is controlled the fuel injection beginning moment and the injection duration of oil sprayer, makes oil sprayer in time eject required fuel oil.Cause that the oil pressure in pipeline produces small sample perturbations when eliminating fuel pump when oil or oil sprayer oil spout, hydro pulse damper is also housed in the fuel oil supply system of some motor, energy during for suction line pressure fluctuation, with this, suppress the pulsation of oil pressure in pipeline, improve the oil spout precision of system.
In the fuel feeding stage, fuel oil enters into fuel pump through oil inlet pipe, under the impact at the filler opening of oil pipe and fuel pump joint at fuel oil for a long time, there will be damaged phenomenon, and the joint of oil pipe also can be thereupon impaired, therefore in fuel delivery way, there will be leakage of oil situation.
Model utility content
The utility model provides a kind of antispray oil guide pipe, solves the problem of the easy splash of oil guide pipe intermediate fuel oil, reaches the object of protecting oil pipe, preventing oil connection leakage of oil.
The purpose of this utility model reaches by the following technical programs:
The utility model comprises oil pipe and joint, in described joint, splatter prevention mechanism is installed, described splatter prevention mechanism comprises internal thread and spacer, internal thread is arranged on inner nosepiece wall, spacer is placed in the joint of joint and oil pipe, on described spacer, have oil outlet and adjustment hole, oil outlet is to the side flanging near oil pipe.Fuel oil in fuel tank is under the draw of fuel pump fast in inflow pump, the fuel oil of rapid flow produces larger momentum, can produce certain impact to the joint of tube inner wall and oil pipe and fuel pump, under impacting for a long time, particularly joint and the filler opening of oil pipe and fuel pump joint can be first impaired for tube inner wall, when serious, oil leakage phenomenon can occur; The splatter prevention mechanism of installing in joint can play the effect that buffering fuel oil rapid flow impacts joint, internal thread is in connected pipes and fuel pump, can also play the effect of sealing, spacer between joint and oil pipe can slow down the speed of the fuel oil of rapid flow, make fuel oil enter into fuel pump by oil outlet, prevent that fuel oil from entering oil inlet hole along tube inner wall, reduce splash; Adjustment hole can regulate when amount of fuel is large, and a part of fuel oil is flowed out by adjustment hole, plays the effect of pressure release; A side flanging at oil outlet near oil pipe, so-called flange arranges projection with regard to referring at the edge of oil outlet, prevent that fuel oil from flowing out to surrounding from oil outlet edge, slowly shape is at a tilt angle with self inertia to make fuel oil, the oil column forming in fuel oil flows through oil outlet certain distance diminishes gradually, outwards splash, diffusion, strengthen antispray effect.
Further, described oil outlet radius is 2～3 times of described adjustment hole radius size.On spacer, the fuel oil of the overwhelming majority flows to fuel pump by oil outlet, and when amount of fuel is large especially, adjustment hole can be shared the oil drain quantity of oil outlet, alleviates the impact dynamics at oil outlet place; The radius of oil outlet is made as 2～3 times of adjustment hole radius, can be applicable to the situation that delivering fuel amount varies in size, and can effectively prevent fuel oil splash, plays the function of protection oil guide pipe.
Further, described oil outlet is concentric with spacer.The spacer arranging between oil pipe and joint is rounded, and the diameter of oil outlet is concentric with spacer, can make fuel oil pass through fast, enters into fuel pump.
Further, also comprise the coating being arranged on spacer and tube inner wall.Fuel oil is for a long time to spacer or tube inner wall impacts, spacer or tube inner wall are easily impaired, coating is set on spacer or tube inner wall can greatly be increased quantity delivered or reduce the pressure that oil pipe is carried, again or the attachment that reduces spacer guarantee that fuel oil is smooth and easy and pass through, increase economic benefit.
The utility model compared with prior art, there is following advantage and beneficial effect:
1, the utility model comprises oil pipe and joint, in described joint, splatter prevention mechanism is installed, described splatter prevention mechanism comprises internal thread and spacer, internal thread is arranged on inner nosepiece wall, spacer is placed in the joint of joint and oil pipe, on described spacer, have oil outlet and adjustment hole, oil outlet is to the side flanging near oil pipe.A side flanging at oil outlet near oil pipe, make fuel oil with self inertia slowly shape at a tilt angle, the oil column forming in fuel oil flows through oil outlet certain distance diminishes gradually, outwards splash, diffusion, strengthen antispray effect.
2, the utility model at fuel oil for a long time to spacer or tube inner wall impacts, spacer or tube inner wall are easily impaired, coating is set on spacer or tube inner wall can greatly be increased quantity delivered or reduce the pressure that oil pipe is carried, again or the attachment that reduces spacer guarantee that fuel oil is smooth and easy and pass through, increase economic benefit.
