During use, be with the anti-mist of oil type prepressing type hydraulic pressure air filter of manual exhaust to be contained on the fuel tank this, element kit 4 is by the fuel tank outside, and the spray-proof oil assembly is by the fuel tank inboard.Under the normal condition, fuel tank internal air pressure is less than or equal to the pressure at expulsion that spring for valve 66 sets, because the effect of air bleeding valve, fuel tank internal and ambient atmosphere are isolated, and this moment, this air filter played a part stable, maintenance fuel tank internal precompressed.
Along with actions such as system's oil cylinder backhauls, system's fluid is back to fuel tank, the fuel tank inner fluid increases, tank internal pressure also progressively rises, to greater than the setting value of air bleeding valve the time, during the pressure at expulsion that promptly sets greater than spring for valve 66, gas upwards backs down valve plate 65, air bleeding valve is opened automatically, discharges internal gas pressure.The action of this moment is as follows, unnecessary gas enters this air filter from passage 12, earlier after air duct 23, passage 22, baffle plate 84, spray-proof oil baffle plate 85 back down valve plate 65, compressed gas valve spring 66 again, promptly open air bleeding valve, through valve plate 65 and valve body 61 gaps, discharge the skeleton 42 of the element kit of flowing through then and filter screen 43 again from valve body annular row air drain 15 and exhaust inclined hole 16, from element kit and the cover cap 3 interstitial row to atmosphere, finish exhaust process.When exhaust, mist of oil will be with hot-air by the exhaust passage, because the tortuosity of passage, mist of oil can constantly be adsorbed on each surface channel, forms oil droplet, after exhaust is finished, relies on the gravity effect to get back to shell 81 bottoms, gets back to fuel tank through outage 21 again.Simultaneously the mist of oil that is not adsorbed by passage is because the effect of filter screen 43, form the mist of oil accumulation on filter screen 43 surfaces, forming oil droplet drops down onto in the long-pending oil groove 11, after exhaust was finished, long-pending oil groove 11 inner fluids flow back into valve inner from exhaust inclined hole 16 after filter screen 43 filters, when inlet valve is opened, be exhaust sealing pad 612 when separating with valve plate 65, fluid is got back to fuel tank by inlet valve and outage 21, realizes anti-mist of oil function.The gas of high speed circulation during along with exhaust, the part oil droplet will be taken away by air, and high speed impact is on spray-proof oil baffle plate 85, because the effect of oblique lower carrier plate on the spray-proof oil baffle plate 85, oil droplet is blocked backflow, flows back to fuel tank through outage 21 again, realizes the spray-proof oil function.
With oil cylinder towards actions such as cylinders, the fuel tank inner fluid is transported in the hydraulic system, this moment, fuel tank fluid reduced, fuel tank internal air pressure also will progressively reduce, and during extremely less than external atmosphere pressure, inlet valve is opened automatically, be exhaust seat 613 below walk downward under the effect of suction, form the gap between valve plate 65 and the exhaust sealing pad 612, air enters fuel tank from the gap, and it is under-voltage to alleviate fuel tank internal.The action of this moment is as follows, ambient atmos enters this air filter through cover cap 3 with the element kit gap, after the air that enters filters through filter screen 43, through skeleton 42, annular row air drain 15 and exhaust inclined hole 16, valve plate passage 26, back down inlet valve then, promptly back down exhaust seat 613, through the gap that forms between valve plate 65 and the exhaust sealing pad 612, again through overpressure cap 62, spray-proof oil baffle plate 85, baffle plate 84, inner casing 82 and shell 81, enter in the fuel tank from passage 12 then, finish under-voltage aspiratory action after.After air-breathing the finishing, gas pressure increases in the fuel tank, and inlet valve is under the restoring force effect of air-breathing spring 614, automatically close inlet valve, be that exhaust seat 613 is up walked under the restoring force effect of air-breathing spring 614, make exhaust sealing pad 612 tightly lean against valve plate 65 belows, close inlet valve.
In the time need reducing pressure to the fuel tank that precompressed is arranged, air-breathing spring 614 is compressed at the top 107 that can directly press bolt 69 with hand by rubber cap 1, makes 65 of exhaust sealing pad 612 and valve plates reserve the space, forms air bleeding valve, and gas is discharged.After exhaust finishes, unclamp bolt 69 tops, under the restoring force effect of air-breathing spring 614, manual exhaust valve is closed automatically, be that exhaust seat 613 is up walked under the restoring force effect of air-breathing spring 614, make exhaust sealing pad 612 tightly lean against valve plate 65 belows, close inlet valve.
When changing element kit, only need screw off nut 2 and be enclosed within nut 2 outside rubber caps 1, can directly take off cover cap 3 and element kit, more renew element kit after, reinstall successively and get final product.
Therefore this air filter has superpressure exhaust, spray-proof oil, anti-mist of oil, under-voltage air-breathing, manual degassing function, has the function that greasy dirt that the mist of oil accumulation is caused filters back backflow fuel tank simultaneously.
The above is a preferred implementation of the present utility model; should be understood that; do not break away from for the person of ordinary skill of the art under the prerequisite of the utility model principle, can also make some distortion and improvement, these also should be considered as belonging to the protection domain of utility model.
