Embodiment
Be below a specific embodiment of the present utility model, first by reference to the accompanying drawings the utility model be described further.
As shown in Figure 1, the integrated pre-compressed air cleaner of a kind of way flow flow-through, there is a dividing plate at cleaner case 7 middle parts, cleaner case 7 is divided into the cavity of upper and lower two end openings by described dividing plate, cleaner case 7 lower chamber ends are arranged on fuel tank, are provided with sealing the first sealing gasket 16 between itself and fuel tank; Filter cleaner top cover 4 is arranged on cleaner case 7 upper cavity openings, filter cleaner top cover 4 is the cylindrical tube shape of an end opening, filter cleaner top cover 4 tips upside down on described cleaner case 7 upper ends, between filter cleaner top cover 4 and cleaner case 7, leave space, filter core 6 is cylindrical tube shape, filter cleaner top cover 4 is withstood in its upper end, lower end props up cleaner case 7 dividing plates, is provided with the 4th sealing gasket 5 between filter core 6 and filter cleaner top cover 4, between filter core 6 and cleaner case 7 dividing plates, is provided with the 3rd sealing gasket 9; Cleaner case 7 dividing plates are passed through filter cleaner top cover 4, lower end in filter cleaner axle 19 upper ends, filter cleaner axle 19 upper ends have screw thread and a wing nut 1 are installed, between wing nut 1 and filter cleaner top cover 4, be provided with pad 2, prevent that dust and moisture from entering filter cleaner from filter cleaner top, filter cleaner axle 19 lower ends have screw thread, between filter cleaner axle 19 and cleaner case 7 dividing plates for being threaded; Between filter cleaner axle 19 and filter cleaner top cover 4, being provided with O type circle 3, the one O type circles 3 is arranged in the groove of opening on filter cleaner top cover 4; In filter cleaner axle 19, be set with pillar 21, pillar 21 lower ends are fixed on cleaner case 7 dividing plates, and filter cleaner top cover 4 is withstood in pillar 21 upper ends.When wing nut 1 is not tightened, reserved certain interval between filter cleaner top cover 4 and spacing pillar 21; Tighten after wing nut 1; the 3rd sealing gasket 9 and the 4th sealing gasket 5 are compressed; between filter cleaner top cover 4 and spacing pillar 21, distance is decreased to zero; continue to tighten wing nut 1; pillar 21 plays a supportive role, and prevents that filter core 6 from damaging, and ensures that wing nut 1 screw-down torque is enough simultaneously; like this when protection filter core 6, prevent wing nut 1 because of screw-down torque too small and loosening.
Breather check valve core 8 is arranged on filter cleaner axle 19 lower ends, and its upper surface is close to cleaner case 7 dividing plate lower surfaces, has air inlet through hole at cleaner case 7 dividing plates and breather check valve core 8 places of being affixed; Being fixed with the second sealing gasket 10 coordinating with breather check valve core 8 at cleaner case 7 dividing plates, is conical surface seal between breather check valve core 8 and the second sealing gasket 10; In the filter cleaner axle 19 of breather check valve core 8 downsides, cover has the first spring 20, for providing a pretightening force to breather check valve core 8; The first spring 20 lower ends are provided with spring support 17; Spring support 17 is fixed on filter cleaner axle 19 lower ends by nut 18; Between filter cleaner axle 19 and breather check valve core 8, being provided with the 2nd O type circle 24, the two O type circles 24 is arranged in the groove of opening on breather check valve core 8.When fuel tank internal air pressure is during lower than external atmosphere pressure certain value, atmospheric pressure acts on breather check valve core 8, overcome the pretightening force of the first spring 20, breather check valve core 8 is opened, ambient air is after filter core 6 filters, via through hole on cleaner case 7, then enter fuel tank through the gap between gas nonreturn valve core 8 and the second sealing gasket 10, complete breathing process.Unclamp nut 18, adjust the first spring 20 pre compressed magnitudes, can adjust suction pressure.
Cleaner case 7 lower chamber one sides are provided with the transition tube in a connection external world, are fixed with an exhaust joint 15 in transition tube outer end by tightening nut 14; Exhaust check valve core 12 is arranged between transition tube and exhaust joint 15; Between exhaust check valve core 12 and exhaust joint 15, be provided with the second spring 13; In transition tube, be provided with exhaust bolt 11, exhaust bolt 11 is positioned at transition tube top; Be connected with exhaust hose 23 in exhaust joint 15 outer ends, exhaust hose 23 is fixed on exhaust joint 15 by larynx hoop 22.In the time that hydraulic system oil return flow is greater than the oil suction flow of pump, fuel tank internal air pressure can raise, and in the time of pressure that fuel tank internal air pressure is set higher than the second spring 13, gas is pushed exhaust check valve core 12 open, from exhaust joint 15, drains into fuel tank outside through exhaust hose 23.Now breather check valve core 8, in closed condition under the acting in conjunction of fuel tank internal air pressure and the first spring 20 pretightening forces, does not have oily vapour to discharge from filter core 6.So, gas-entered passageway and the exhaust passage of filter cleaner are isolated, thereby prevent filter core 6 adsorbed oil vapour and lost efficacy, and extend the working life of filter core 6.Unclamp tightening nut 14, adjust the degree of depth that is screwed into of exhaust joint 15, thereby regulate the second spring 13 pre compressed magnitudes, can regulate the exhaust pressure of filter cleaner.The gas with oily vapour of discharging from filter cleaner, drains into other positions by exhaust hose 23, can avoid oily contaminated vapor equipment.Exhaust bolt 11 is assemblied on cleaner case 7, need to overhaul fuel tank or filter cleaner time, can turn on exhaust bolt 11, and the pressurized gas of fuel tank internal is discharged.
The utility model has the advantages that:
1, between filter cleaner top cover 4 and filter cleaner bearing 7, have pillar 21 to play a supportive role, while preventing from tightening wing nut 1, damage filter core 6, ensure that wing nut 1 screw-down torque is enough simultaneously, prevent wing nut 1 because of screw-down torque too small and loosening;
2, the O type circle 3 being arranged in filter cleaner top cover 4 grooves forms sealing together between filter cleaner axle 19 and filter cleaner top cover 4, prevents that dust and moisture from entering filter cleaner from filter cleaner top;
3, adopt the method for one-way flow that the gas-entered passageway of filter cleaner and exhaust passage are kept apart, thereby prevent filter core 6 adsorbed oil vapour and lost efficacy, extend the working life of filter core 6;
4, intake and exhaust non-return valve core adopts plug-in type structure, and intake and exhaust pressure can regulate within the specific limits, significantly the Applicable scope of improving product;
5, intake and exhaust non-return valve core adopts metal and oil resistant rubber sealing, because quality of rubber materials is softer, easily deforms, and between spool and valve body, can forming surface contact good sealing effect; Intake and exhaust non-return valve core adopts conical surface seal simultaneously, further lift-off seal effect;
The gas with oily vapour of 6, discharging from filter cleaner, can drain into other positions by exhaust hose 23, can avoid oily contaminated vapor equipment.
