Description

Oil filter valve cabable of stop

The utility model belongs to a kind of oil filter that is used for hydraulic pressure active element import fluid.

In order to guarantee the works fine state of hydraulic equipment, the import fluid of oil pump will reach certain turbidity test, present most of hydraulic equipment, be that oil purifier is set in fuel tank, also have and in Partition board for fuel tank, place filter screen, after use a period of time, the many foreign material of adhesion on oil purifier, the oil cleaner screen, influence its oil filling capacity, at this moment need to clean oil purifier, oil cleaner screen; Service time is when long slightly, oil purifier, oil cleaner screen breakage, need to change, operate cumbersomely, need open fuel tank cap, and oil is drained, operating time is long, and easily pollute working environment, and, will cause pump and various valve member premature damage often owing in time do not clean oil purifier, oil cleaner screen.

The purpose of this utility model provides a kind of oil strain valve that ends, and it is convenient to clean or change, and can accomplish often to wash Chang Xin, keeps the fluid of hydraulic system often to clean, and the oil strain valve is unblocked, improves the working life and the utilization efficiency of pump valve element.

The purpose of this utility model is achieved in that and brings into, the housing of oil outlet, and filter core is housed in it, and its technological scheme main points are: loam cake is arranged at the top of housing, and the filler opening place of housing connects valve body, is equipped with by spool in the valve body.

The utility model has the advantages that: can clean easily and change, often wash Chang Xin, keep the fluid of hydraulic system often to clean, the oil strain valve can be unblocked, thereby improved the working life and the utilization efficiency of pump valve element.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model embodiment 1 structural representation.

Fig. 2 is the utility model embodiment 2 structural representations.

See Fig. 1, embodiment's 1 concrete structure of the present utility model is as follows: housing 2 has filler opening 11 and oil outlet 14, the top scyewed joint loam cake 1 of housing 2, and the filter core 3 of packing in the housing 2, thread section is arranged at filter core 3 bottoms, is screwedly mounted on the bottom of housing 2.The whole valve body 8 that connects in filler opening 11 places is equipped with spool 4 in the valve body, there is spring 9 lower end of spool 4.Stationary gland 6 on the valve body 8, and the manipulatable end of spool 4 passes from gland 6, and jackscrew 7 is arranged on the gland 6, and locating slot 5 is arranged on the spool 4, and the end of jackscrew 7 can withstand in the locating slot 5.Filler opening 11 ends and oil outlet 14 ends of housing 2 are assembled

flange

10 and 13 respectively.

See Fig. 2, embodiment 2 housing 2 oil outlets punishment sports association connects valve body 8, adopts Bolt Connection, and the other parts structure is with embodiment 1.

Working procedure: during assembling, valve body 8 and fuel tank oil outlet are connected, the oil outlet and the pump inlet of housing 2 are connected, this moment, valve was an open state, and fluid enters in the pump then by filter core, is in normal working; When needs cleaned, a hand was pressed lower valve core 4, and another hand-screw jackscrew 7 is gone in the locating slot 5 of spool 4, and spool 4 with top cover under the hand-screw 1, screws off spool 3 then with valve closing, and is promptly capable of washing.

Claims
