Abstract
The invention discloses an oil guiding pipe having an anti-spattering function. The oil guiding pipe comprises an oil pipe and a connector. An anti-spattering mechanism is installed in the connector and comprises an internal thread and an isolating piece. The internal thread is arranged on an inner wall of the connector, the isolating piece is placed at the joint of the connector and the oil pipe and provided with an oil outlet hole and an adjusting hole, and the oil outlet hole is turned up towards one side close to the oil pipe. The isolating piece between the connector and the oil pipe can slow down the speed of quickly flowing fuel, the fuel enters a fuel pump through the oil outlet hole and is prevented from entering an oil inlet hole along an inner wall of the oil pipe, the oil outlet hole is turned up towards one side close to the oil pipe, namely a protrusion is arranged on the edge of the oil outlet hole, the fuel is prevented from flowing around from the edge of the oil outlet hole and slowly forms an inclination angle by means of inertia, an oil column formed within a certain distance where the fuel flows through the oil outlet hole becomes small gradually, and the fuel cannot be spattered and diffused outwards.
Description
Technical field
The present invention relates to fuel delivery equipment, specifically refer to the oil guide pipe with antispray function.
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 mainly is 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 by fuel pump from fuel tank, pumping, by fuel filter elimination impurity, through the 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, the hydro pulse damper also is housed in the fuel oil supply system of some motor, energy during for the 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 fuel oil for a long time of the filler opening of oil pipe and fuel pump joint, there will be damaged phenomenon, and the joint of oil pipe also can be thereupon impaired, therefore in the fuel delivery way, there will be the leakage of oil situation.
Summary of the invention
The invention provides the oil guide pipe with antispray function, solve the problem of the easy splash of oil guide pipe intermediate fuel oil, reach the purpose of protecting oil pipe, preventing the oil connection leakage of oil.
Purpose of the present invention reaches by the following technical programs:
The present invention includes 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 at 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 be regulated when amount of fuel is large, a part of fuel oil is flowed out by adjustment hole, plays the effect of pressure release; At the side flanging of oil outlet near oil pipe, so-called flange arranges projection with regard to referring at the edge of oil outlet, prevent that fuel oil is from flowing out to surrounding on the oil outlet edge, slowly shape is at a tilt angle with self inertia to make fuel oil, the oil column formed in fuel oil flows through the 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 was large especially, adjustment hole can be shared the oil drain quantity of oil outlet, alleviated 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 the delivering fuel amount varies in size, and can effectively prevent the fuel oil splash, plays the function of protection oil guide pipe.
Further, described oil outlet is concentric with spacer.The spacer arranged 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 be 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 increase 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.
Further, as preferably, described coating is the mixture of solvent-free modified epoxy and ceramic fine bead and the mixture of ceramic fine bead.Solvent-free modified epoxy is as the film forming matter of coating, with ceramic fine bead, carry out filler, can effectively improve the anti-adhesion of coating, improve the tube inner wall surface finishment high, reduce transporting resistance, and in filler, contain ultraviolet light absorber, improved the weatherability of coating, extended the working life of coating.
The present invention compared with prior art, have following advantage and a beneficial effect:
1, the present invention includes 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.At oil outlet near a side flanging of oil pipe, make fuel oil with self inertia slowly shape at a tilt angle, the oil column formed in fuel oil flows through the oil outlet certain distance diminishes gradually, outwards splash, diffusion, strengthen antispray effect.
2, coating of the present invention is the mixture of solvent-free modified epoxy and ceramic fine bead and the mixture of ceramic fine bead.Solvent-free modified epoxy is as the film forming matter of coating, with ceramic fine bead, carry out filler, can effectively improve the anti-adhesion of coating, improve the tube inner wall surface finishment high, reduce transporting resistance, and in filler, contain ultraviolet light absorber, improved the weatherability of coating, extended the working life of coating.
