Abstract
The utility model discloses a sealing oil tank air compensation device, comprising an air cleaner (1) arranged inside a sealing oil tank (7). An air conduit (2) is connected with the air cleaner (1); a safety valve (3) is connected with the other end of the air conduit (2); a reversing valve (4) is connected with the right end of the safety valve (3); an air supply dual-connecting piece (5) with the functions of filter and pressure-releasing is arranged on the right end of the reversing valve (4); the right end of the air supply dual-connecting piece (5) is connected with an air inlet pipe (6). The air compensation device adopts a secondary filter structure so that clean compressed air enters the sealing oil tank (7) after repeated filtrations, and thereby, the air pressure of the sealing oil tank (7) is compensated without polluting the inner part of the sealing oil tank (7). The utility model also has the advantages of simple structure, small occupied space, wide application range, good using effect, and the like.
Description
Technical field
The utility model relates to a kind of compensated with air device, especially a kind of leakproof fuel cell compensated with air device.
Background technique
At present, existing domestic all hydraulic station fuel tank all adopts air-strainer and atmosphere to connect or adopts Qi Rang ftercompction mode, and fuel tank internal air pressure is compensated and regulates, and guarantees the air pressure balance of fuel tank internal.But this sample loading mode has two shortcomings; At first, adopt air-strainer directly to be communicated with atmosphere, airborne small dust easily enters in the fuel tank, pollutes oil, and damages hydraulic element; Secondly, gas Rang ftercompction mode requires and large and medium-sized hydraulic station and inapplicable having living space because manufacturing technology and the volume restrictions of gas Rang only adapt to small-sized fuel tank, and it are big to account for volume.
The model utility content:
The purpose of this utility model is: a kind of leakproof fuel cell compensated with air device is provided, it can be at the air in the compensation closed tank, make the air pressure in the closed tank keep stable, can avoid simultaneously dust in air to pollute oil, and volume is little, simple in structure, using scope is wide, to overcome the deficiencies in the prior art.
The utility model is achieved in that leakproof fuel cell compensated with air device, comprise a air-strainer in the passage of carrying out that is arranged on leakproof fuel cell, on air-strainer, be connected with an air conduit, the other end at air conduit is connected with a safety valve, right-hand member at safety valve is connected with a selector valve, right-hand member at selector valve is connected with a source of the gas bigeminy part with filtration and decompression, and the right-hand member of source of the gas bigeminy part is connected with suction tude.
Be provided with a housing outside air-strainer, housing is installed in the leakproof fuel cell.
Owing to adopted technique scheme, compared with prior art, the utility model adopts the structure of secondary filter, make clean pressurized air by after the multiple times of filtration, enter in the leakproof fuel cell, can play compensating action to the pressure change of leakproof fuel cell, can guarantee that again leakproof fuel cell inside is not contaminated.Advantages such as the utility model also has simple in structure, and it is little to take up room, applied widely, and using effect is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the structure of leakproof fuel cell compensated with air device as shown in Figure 1, make a housing 8 earlier, existing air-strainer 1 is installed in the housing 8, and housing 8 is installed in carrying out in the passage of leakproof fuel cell 7, and will carry out passage and be connected with air conduit 2, the other end of air conduit 2 connects a safety valve 3, the right-hand member of safety valve 3 connects a selector valve 4, right-hand member at selector valve 4 connects a source of the gas bigeminy part 5 with filtration and decompression, and the right-hand member of source of the gas bigeminy part 5 is connected with suction tude 6.
In use, clean pressurized air enters into source of the gas bigeminy part 5 from suction tude 6 and filters and reduce pressure, when hydraulic system is used, leakproof fuel cell 7 is inner because the pressure change that the hydraulic oil Volume Changes causes need be carried out atmospheric pressure compensating, earlier the air behind the primary purification is entered into air conduit 2 by selector valve 4, and deliver in the air-strainer 1, air enters behind double purification in the leakproof fuel cell 7, realizes atmospheric pressure compensating.
Selector valve 4 can regulate are compressed-air actuated to be gone out atmospheric pressure and pressurized air is cut off or connects; Safety valve 3 is for when the leakproof fuel cell 7 air pressure inside superelevation, carries out safe exhaust and discharges, and guarantees air pressure balance; Specifically be to start when hydraulic system, oil level reduces, and volume of air increases, and air pressure reduces, and compensation device is to carrying out tonifying Qi in the leakproof fuel cell 7; When the oil level rising, volume of air reduces, and pressure increases, and safety valve 3 is opened, and carries out exhaust, guarantees leakproof fuel cell 7 internal air pressure balances; The effect of protection air-strainer 1 had both been played in the installation of housing 8, had made things convenient for the installation of air-strainer 1 in leakproof fuel cell 7 again.
After pressurized air of the present utility model carries out multiple times of filtration and dewaters, guarantee that leakproof fuel cell 7 inside are not contaminated; And leakproof fuel cell 7 and all pipelines all adopt all-sealed structure, have prevented that effectively pollutant such as dust from entering leakproof fuel cell 7 and polluting oil, have guaranteed the reliability of system and have saved cost; And volume is little, and simple in structure, using scope is wide, is adapted to all types hydraulic station of pressurized air occasion.
Claims (2)
1. leakproof fuel cell compensated with air device, comprise a air-strainer (1) in the passage of carrying out that is arranged on leakproof fuel cell (7), it is characterized in that: on air-strainer (1), be connected with an air conduit (2), the other end at air conduit (2) is connected with a safety valve (3), right-hand member at safety valve (3) is connected with a selector valve (4), right-hand member at selector valve (4) is connected with a source of the gas bigeminy part (5) with filtration and decompression, and the right-hand member of source of the gas bigeminy part (5) is connected with suction tude (6).
