Abstract
The invention relates to a no-leakage declination single-cylinder diesel engine oil tank switch which comprises an oil tank switch body, a grip, a valve core, a fixed pin, a fastening screw cap, a valve core cone, a cutting sleeve and a seal ring, wherein the grip is fixedly connected with the valve core through the fixed pin; the valve core is arranged at the top end in the oil tank switch body through the fastening screw cap; the lower end of the valve core is provided with the valve core cone; the valve core is provided with the cutting sleeve; and the seal ring is arranged between the cutting sleeve and the valve core cone. The included angle of the declination of the axial line of the oil outlet pipe on the oil tank switch body to the side of the mounting surface of the oil tank switch body is 1-30 degrees, so that the oil pipe can be directly concealed in the slit between the oil tank and the machine body and can not be exposed outside after the oil pipe is installed on the oil outlet pipe, and thus, the integral structure is more beautiful, thereby avoiding oil leakage due to unexpected pull fall-off caused by oil pipe exposure, or preventing the oil outlet pipe from rupture due to collision caused by oil outlet pipe exposure. The oil tank switch in such a structure has the characteristic of oil leakage prevention in the prior art, and can effectively overcome the defects caused by oil pipe exposure since the oil pipe is concealed inside.
Description
Technical field
The present invention relates to a kind of diesel engine part, relate in particular to a kind of Fuel Tank of Single-Cylinder Diesel Engines switch.
Background technique
Leak, gas leakage, leakage of oil is modal fault in the diesel engine using process, accounts for more than 80% of whole diesel engine fault; And the fuel tank leakage of oil is one of fault the most outstanding in " three leak ", in all diesel engine operational failures, the fuel tank leakage of oil always makes number one.Existing fuel tank switch is as shown in Figure 1: comprise fuel tank switch body 1, handle 2, spool 3, fixing pin 4, fastening nut 5, valve core cone 6, cutting ferrule 7, delivery connection 8, go out oil draining bolt 9 and seal ring 10, fuel tank switch body 1 comprises filter core joint 11 and oil-feed through hole 12, one side of fuel tank switch body 1 is filter core joint 11, its inner hollow, for oil-feed through hole 12, handle 2 is fixedly connected with spool 3 by fixing pin 4, spool 3 is arranged on the top of fuel tank switch body 1 by fastening nut 5, in spool 3 lower ends, valve core cone 6 is set, offer side oil inlet hole 61 and vertical oil outlet 62 in valve core cone 6, side oil inlet hole 61 is corresponding with oil-feed through hole 12 at the horizontal position axial-rotation, vertically oil outlet 62 is vertical with side oil inlet hole 61, be provided with cutting ferrule 7 on spool 3, between cutting ferrule 7 and valve core cone 6, seal ring 10 is set, delivery connection 8 is screwed in the bottom of fuel tank switch body 1 by going out oil draining bolt 9, go out oil draining bolt 9 open-toppeds upwards, bottom is provided with oil outlet 91, delivery connection 8 is interior arranges horizontal oil outlet 81, at fuel tank switch body 1, delivery connection 8 and go out between oil draining bolt 9 to be provided with seal ring 10, wherein, filter core joint 11 is connected with filtering core device in fuel tank, between other each parts, all closely connect, handle 2 is used for controlling fuel-displaced in fuel tank, but, when diesel engine works long hours, whole equipment is significantly shaken, cause the oil draining bolt 9 that goes out that is screwed in fuel tank switch body 1 lower end to become flexible, to such an extent as to can not closely be connected between delivery connection 8 and fuel tank switch body 1, oil accident will occur like this, produced waste for the oil in fuel tank, reduced oily utilization efficiency, the also easily larger pollution of environment structure to external world, be difficult to clean, using this fuel tank and producing above-mentioned technical problem is prevalent among industry now, in order to solve this defect, people have developed a kind of ne-leakage Fuel Tank of Single-Cylinder Diesel Engines switch, as shown in Figure 2 to 3, comprise fuel tank switch body 1, handle 2, spool 3, fixing pin 4, fastening nut 5, valve core cone 6, cutting ferrule 7 and seal ring 10, wherein, on fuel tank switch body 1, with the oil outlet tube that goes out oil hole 14 and oil outlet end 13, be connected as a single entity, and the axis that goes out oil hole 14 is parallel with the attachment face of fuel tank switch.Owing to by original, going out oil draining bolt and delivery connection omits, directly fuel tank switch body 1 is injection molded into to the integrative-structure that contains oil outlet end 13 and go out oil hole 14, make whole structure more simple, no matter how diesel engine operates this integral structure, fuel tank not there will be the loosening possibility of oil draining bolt and delivery connection, effectively solved the defect of this link leakage of oil, improved greatly oily utilization efficiency, also improved whole environment, reduced the possibility of polluting, simultaneously, cost has also been saved in such design, has improved economic benefit.But, because the axis that goes out oil hole 14 is parallel with the attachment face of fuel tank switch body 1, after oil pipe is arranged on fuel tank switch body 1, oil pipe is exposed to outside fuel tank and body, not only affects attractive in appearance, and oil pipe is easy to be pulled disengaging by accident, cause whole diesel engine to work, because fuel tank switch body 1 is moulding, material is more crisp, easily collide fracture with the oil outlet tube that goes out oil hole 14, once fracture will integral replacing.
Summary of the invention:
The purpose of this invention is to provide a kind of ne-leakage drift angle Fuel Tank of Single-Cylinder Diesel Engines switch, can not only stop leakage of oil, be more convenient for making oil pipe to be hidden in the gap between fuel tank and body, avoid oil pipe to expose, prevent that oil outlet tube from being collided fracture.
The technological scheme that the present invention takes is:
A kind of ne-leakage drift angle Fuel Tank of Single-Cylinder Diesel Engines switch, comprise the fuel tank switch body, handle, spool, fixing pin, fastening nut, valve core cone, cutting ferrule and seal ring, wherein, the fuel tank switch body comprises the filter core joint, the oil-feed through hole, oil outlet end, go out oil hole and oil outlet tube, the filter core joint is arranged on a side of fuel tank switch body, its inner hollow, for the oil-feed through hole, the lower end of fuel tank switch body arranges oil outlet end, oil outlet tube is arranged on a side of oil outlet end, go out the center that oil hole is arranged on oil outlet tube, wherein, at filter core joint arranged outside seal ring, described handle is fixedly connected with spool by fixing pin, spool is arranged on the apical position in the fuel tank switch body by fastening nut, in the spool lower end, valve core cone is set, offer side oil inlet hole and vertical oil outlet in valve core cone, the side oil inlet hole is corresponding with the oil-feed through hole at the horizontal position axial-rotation, vertically oil outlet is vertical with the side oil inlet hole, be provided with cutting ferrule on spool, between cutting ferrule and spool centrum, seal ring is set, it is characterized in that: the angle that the axis of oil outlet tube turns to attachment face one lateral deviation of fuel tank switch body is 1 °～30 °.
Further, the angle that the axis of oil outlet tube turns to attachment face one lateral deviation of fuel tank switch body is 5 °～10 °.
Because the present invention has been offset 1 °～30 ° by fuel-displaced siphunculus to the attachment face of fuel tank switch body, after oil pipe is arranged on oil outlet tube like this, oil pipe can directly be hidden in the gap of fuel tank and body, can not be exposed to outside, make integral body more attractive in appearance, avoided producing unexpected OK a karaoke club and coming off and cause leakage of oil because oil pipe exposes, or because exposing by collision, oil outlet tube ruptures, the fuel tank switch of this structure had both possessed the oil-leakage-prevention characteristic of prior art, can effectively solve oil pipe again built-in, stop the deficiency that oil pipe exposes generation.
