Abstract
The utility model discloses an air filter with a lock on the side. The air filter with the lock on the side is characterized by comprising an installation flange (6) installed on a joint of a hydraulic oil tank. A connecting flange (5) is arranged at the upper end of the installation flange (6) and a cap (1) is arranged at the upper end of the connecting flange (5). One side of the cap (1) is hinged with the connecting flange (5) while the other side of the cap (1) is provided with a lock (2). The cap (1) is internally provided with a filter element (9). A splash-proof oil baffle disc (12) is installed on the lower part of the filter element (9). A compression spring (10) is arranged between the cap (1) and the splash-proof oil baffle disc (12). The installation flange (6) is internally provided with an oil filling filter screen (7). The air filter with the lock on the side provided by the utility model is simple and practical in structure, waterproof, dustproof, splash-proof and attractive in appearance, and filters air.
Description
Technical field
The utility model relates to the device that engineering machinery vehicle hydraulic system air is filtered.
Background technique
At present, oily on the hydraulic system of engineering machinery vehicle for preventing by steathily, the air-strainer with lock of use (annotate: the effect of air-strainer is the filtration of oiling and air).A kind of is with common padlock; It is neither attractive in appearance, is prone to again get rusty, and another kind is mounted in the lock on oil filler top; But this structure can not waterproof; Be prone to cause water to get into fuel tank again, and cause fluid to spatter outward, can not satisfy the whole requirement of modern project machinery owing to rocking in the engineering machinery vehicle running process.
Summary of the invention
The purpose of the utility model is exactly the deficiency to above-mentioned existing product, and the side air-strainer with lock of a kind of simple in structure, waterproof, antirust, splashproof, practicality, beautiful shape is provided.
The technological scheme that the utility model adopts is following:
A kind of side air-strainer with lock is characterized in that it comprises the mounting flange that is installed on the hydraulic oil container interface, and the upper end of mounting flange is provided with adpting flange; The upper end of adpting flange is equipped with the cover cap, and a side and the adpting flange of cover cap are hinged, and opposite side is equipped with lock; Said cover cap inside is equipped with filter core; The bottom of filter core is equipped with the splashproof oil baffle disc, is provided with holddown spring between cover cap and the splashproof oil baffle disc, and the inside of mounting flange is equipped with filling strainer.
The oil return aperture is arranged around the said splashproof oil baffle disc.
Fix through the dead bolt screens between said lock and the adpting flange.
Adopt snap ring to fix between said dead bolt and the lock.
Said cover cap and adpting flange adopt elastic cylindrical pin hinged.
Adopt screw to be connected between said adpting flange and the mounting flange.
Adopt the sealing gasket sealing between said mounting flange and the fuel tank.
The beneficial effect of the utility model has:
Simple and practical, can waterproof, antirust, splashproof, beautiful shape, the line space of going forward side by side gas filters.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the plan structure schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further:
Like Fig. 1, shown in 2, the utility model comprises the mounting flange 6 that is installed on the hydraulic oil container interface, and the upper end of mounting flange 6 is provided with adpting flange 5, adopts screw 14 to be connected between adpting flange 5 and the mounting flange 6.The upper end of adpting flange 5 is equipped with cover cap 1, and cover cap 1 one sides and adpting flange 5 adopt elastic cylindrical pin 11 hinged, and cover cap 1 another side is equipped with lock 2, through dead bolt 4 screens, adopts snap ring 3 fixing between said lock 2 and the dead bolt 4 between lock 2 and the adpting flange 5.The inside of cover cap 1 is equipped with filter core 9, and the bottom of filter core 9 is equipped with splashproof oil baffle disc 12, and oil return aperture 13 is arranged around the splashproof oil baffle disc 12, and the fluid that externally spatters reclaims.Be provided with holddown spring 10 between cover cap 1 and the splashproof oil baffle disc 12, the inside of mounting flange 6 is equipped with filling strainer 7, adopts sealing gasket 15 sealings between mounting flange 6 and the fuel tank.
At work, when fuel tank liquid level descended, air arrived fuel tank from atmosphere through cover cap 1, filter core 9, splashproof oil baffle disc 12 and filling strainer 7, makes the tank pressure balance, prevented that the systems pumps suction is empty; When fuel tank liquid level rose, air was discharged to the atmosphere through filling strainer 7, splashproof oil baffle disc 12, filter core 9 and cover cap 1 from fuel tank, makes the tank pressure balance, prevents the fuel tank compressive deformation.Engineering machinery vehicle in the process of moving because the fluid that jolts can outer spatter, this air-strainer is provided with the oil return aperture 13 of splashproof oil baffle disc 12 and splashproof oil baffle disc periphery, can prevent effectively that fluid from spattering and fluid is reclaimed outward.
When the hydraulic system of engineering machinery vehicle need be refueled, open lock 2 with key 8, start cover cap 1, from filling strainer 7, refuel.Because lock 2 is installed in the side and lock has dust cap, can waterproof and dustproof.
Other undeclared part that the utility model relates to is identical with existing technology.
