The porous plug that has in the market various single patterns, as dust-protection type, damp-proof, pressure release type.
The applying date is 2006.9.30, and application number is 200620127834.X, and notice of authorization number is the disclosed a kind of adjustable porous plug of CN200958591Y, can realize ventilative unobstructedly, keeps pressure stability, preventing oil spill.
The applying date is 2010.01.26, and application number is 201020114683.0, and notice of authorization is number for CN201582381 U discloses a kind of porous plug, can realize ventilative thoroughly, the effect of dust protection, seepage-proof oil.
But fuel tank and gearbox need to prevent dust under many circumstances, moistureproof, pressure release seepage-proof oil simultaneously, so the object of this invention is to provide a kind of Multifunctional permeable vent plug, possesses the function of dustproof, moistureproof, pressure release, pressure release seepage-proof oil simultaneously.
Summary of the invention
For solving the problems of the technologies described above, of the present utility model a kind of for fuel tank, the Multifunctional permeable vent plug of speed reducer, comprise outer cover, be arranged on the filter cup in outer cover, lubricating cup, described filter cup is connected by suction valve with described lubricating cup, the top of described filter cup is provided with inlet hole, in described filter cup, be provided with filter layer, described suction valve is connected with suction tude, in described lubricating cup, be provided with clean oil, in described lubricating cup, be also provided with air pipe, described lubricating cup is fixedly connected on casing, described air pipe is connected with casing, the opening being connected with air pipe in described casing is provided with filter screen, one side of described lubricating cup is provided with outlet valve.
As the further improvement to technical solutions of the utility model, a kind of Multifunctional permeable vent plug for fuel tank, speed reducer of the present utility model, its filter layer comprises at least one filter cotton layer and at least one desiccant layer.
As the further improvement to technical solutions of the utility model, lubricating cup lower left corner parts are provided with blowdown bolt, and the upper right corner of lubricating cup is provided with refueling bolt.When work a period of time, clean oil emulsification and while being mixed with moisture in cup, outside can being discharged glass, separately refills clean oil by refueling bolt hole.
Further improvement as to technical solutions of the utility model, is provided with wire gaze in inlet hole.Wire gaze can play further filtration to the air entering.
The beneficial effects of the utility model are as follows:
1, most of dust is subject to gravity natural subsidence in air passageways, at porous plug top, has filter layer, by filter cotton, small particle filtering is filtered out, and has so just played dustproof effect;
2, when gas passes through desiccant layer, the water vapour in siccative adsorbed gas, reaches moistureproof object; Siccative has regeneration function, can repeatedly use.
3, in porous plug, there is mechanical decompression function, when fuel tank internal surpasses setting pressure, pressure relief device releasing pressure automatically.
4, porous plug bottommost, the filter screen that can make Oil-gas Separation that has wire gaze to make, when the oil that splashes out in fuel tank or the foam in oil arrive filter screen, filter screen only allows gas to pass through, oil after-tacks and is attached on filter screen, and oily gravitate can slowly flow back to fuel tank.
5, this apparatus structure is compact, reduces installation trouble and takes up room, and uses, easy to maintenance, makes, operating cost is low.
6, this device inlet air is pure, can protect oil in casing.
