Abstract
The utility model discloses a self-closing oil suction filter used for oil passage filtering in the hydraulic system of a mechanical device, comprising a filter case, a filter core and a filter head. The base of the oil suction opening of the filter case is provided with a movable push rod. The upper section of the push rod is provided with a compressed spring, and the lower end is provided with a sealing gasket. When washing in dismounting or repair is required, the filter head can be dismounted, and the filter core can be taken out. Under the action of the compressed spring, the push rod is lifted. At the same time, the sealing gasket seals the oil suction hole on the base for blocking the oil passage. Thus, the oil in the hydraulic system does not have to be drained. The utility model has the advantages of simple and convenient washing in dismounting and repair, simple structure and high work efficiency.
Description
The utility model relates to and is used for the self sealing oil suction oil purifier that oil circuit filters in a kind of machinery hydraulic system.
Oil suction oil purifier is in the past only considered the filtration of inlet port oil circuit.When oil-filter strainer is stopped up by dirt, need to clean or when changing fuel filter element, must be with the fluid emptying in the whole hydraulic pipe line.Influence working efficiency to the maintenance ， And that makes troubles.
The purpose of this utility model is to overcome above-mentioned defective, provide a kind of unpicks and washes, keeps in repair and maintain easy self sealing oil suction oil purifier, after the use, can obviously increase work efficiency.
The utility model is provided with filter housing, filter core and filter.The base at filter housing inlet port place is provided with movable push bar.The push rod epimere is provided with stage clip, the lower end is provided with sealing gasket.
One embodiment below is provided, and accompanying drawing is the topology view of present embodiment.
Present embodiment be provided with filter housing (1), with filter housing (1) by the filter (7) of screw attachment, be provided with filter core (6) in the filter housing (1).Filter (7) and filter core (6) scyewed joint, the inlet port place of filter housing (1) is provided with base (2).Filter housing (1) side sets out oilhole (8).Oil-sucking hole is set on the base (2), and (9), And are provided with movable push bar (3), and push rod (3) epimere is provided with stage clip (4), the lower end is provided with sealing gasket (5).
After filter core (6) was put in the filter housing (1), its bottom props up the spring force that push rod (3) top ， And overcomes stage clip (4) made the sealing gasket (5) of push rod (3) lower end separate with base (2), and maintenance oil-sucking hole (9) is unimpeded.Unpick and wash or maintenance etc. the time, unload filter (7) when need, take out filter core (6), at the same time, push rod (3) is in stage clip (4) effect rising down, and sealing gasket (5) is sealed the oil-sucking hole (9) on the base.Oil circuit is ended, and need not the fluid emptying in the hydraulic system, unpick and wash, keep in repair or maintain quite easy, the simple ， And of Jie structure has obviously improved working efficiency.
Claims (1)
1, a kind of self sealing oil suction oil purifier with filter housing, filter core and filter, it is characterized in that: the base (2) at filter housing (1) inlet port place is provided with movable push bar (3), and push rod (3) epimere is provided with stage clip (4), the lower end is provided with sealing gasket (5).
