Abstract
The utility model relates to a pressured air filter which is used for a pressurized fuel tank. The utility model is mainly composed of a cylindrical outer casing, a spring seat, a spring, a filter core, an air outlet valve, a valve core, a positioning slice, etc. The pressured air filter can make the pressurized fuel tank keep the predetermined pressure constant. Namely, when the air pressure of the pressurized fuel tank is higher than the predetermined pressure, the pressured air filter can make the pressure of the fuel tank be reduced. When the air pressure of the pressurized fuel tank is lower than the atmospheric pressure, the pressured air filter can make the pressure of the fuel tank be raised. Thus, the pressured air filter can keep the predetermined pressure all along.
Description
The utility model is a kind of pressure-increasing air purifier that is used for pressurized reservoir.
The present air-strainer that uses, its application area is narrower, only is applicable to general fuel tank usually.For pressurized reservoir, because it can not keep the gas pressure in the fuel tank, so be difficult to satisfy the requirement of pressurized reservoir.
The purpose of this utility model is to provide a kind of novel pressure-increasing air purifier for pressurized reservoir, it can make the gas in the pressurized reservoir keep predetermined pressure constant, promptly it can make the fuel tank step-down when the pressure in the pressurized reservoir is higher than predetermined pressure or increases along with the rising of oil temperature, it can boost by fuel tank when the gas pressure in the fuel tank is lower than barometric pressure, thus the predetermined pressure of remaining.
The utility model mainly is made up of circular housing 1, spring seat 2, spring 3, filter core 4, gas outlet valve 6, sealing 7, spool 9, location piece 10 etc.Spool 9 is located and is installed on the base 11 by location piece 10; Sealing 7, gas outlet valve 6, spring 3, spring cup 2 are set on the spool successively, are shaped on through hole 12 on the spool, are shaped on through hole 13 on the gas outlet valve, seal 7 bottom surfaces and are plugged on the through hole 13.The utility model is simple in structure, cost is low, stable and reliable working performance, has favorable economic benefit.
Below with reference to accompanying drawing in detail embodiment of the present utility model is described in detail:
Fig. 1 is a structural drawing of the present utility model,
Among the figure, pressure-increasing air purifier through hole base 11 is installed on the pressurized reservoir, and 9 of base 11 and spools are by sealing gasket 8 sealings.5 is flexible.During work, when the pressure in the pressurized reservoir is lower than barometric pressure, ambient air enters filter cleaner through filter element filtering, by the through hole on the gas outlet valve 13 and back down the sealing 7, enter pressurized reservoir by the through hole on the spool 12 and location piece 10 through base again, increasing the air pressure in the fuel tank, up to reaching balance, thereby guaranteed the safety of hydraulic system with atmospheric pressure.
When increasing that air pressure increases and surpassing the set pressure (0.35bar or 0.7bar) of pressure-increasing air purifier because of oily temperature rise, mist of oil behind the pressurized reservoir inner fluid work certain hour, pressurized gas in the fuel tank enter the annular space of gas outlet valve bottom by the through hole on location piece and the spool 12, and the elastic force effect that overcomes spring 3 is gas outlet valve jack-up, and pressurized gas are then discharged outside the filter cleaner through filter core through the gap between spool and the gas outlet valve again.When pressure and the external world reached balance, gas outlet valve 6 is returning position under the elastic force effect of spring 3, and pressurized reservoir keeps predetermined pressure again.
Claims (1)
1, a kind of pressure-increasing air purifier that is used for pressurized reservoir, it includes circular housing 1, base 11, filter core 4, of the present utility modelly is characterised in that it also includes spool 9, sealing 7, gas outlet valve 6, spring 3, spring seat 2, location piece 10 etc.Spool 9 is located and is installed on the base 11 by location piece 10; Sealing 7, gas outlet valve 6, spring 3, spring cup 2 are set on the spool successively; Be shaped on through hole 12 on the spool, be shaped on through hole 13 on the gas outlet valve, the bottom surface of sealing 7 is plugged on the through hole 13.
