Description
Technical field
It is a kind of filter that the utility model relates to, a kind of filter that is installed in vavuum pump suction nozzle place of more specifically saying so.
Background technology
Vavuum pump is a kind of instrument that is used for the air-conditioning equipment maintenance.During snow kind in changing air-conditioner, vavuum pump is used for the air of air-conditioner compressor is taken out.But in using the process of vavuum pump, because the different factor of air conditioner working environment, vavuum pump tends to the dust in the compressor, small foreign body together in the suction vavuum pump.Subtitle substance usually can cause the obstruction of the inner extract system of vavuum pump after entering in the vavuum pump.So caused the life-span of vavuum pump short, the repair rate height.Therefore, in working practice, have screen pack is set in vavuum pump, these screen packs can filter out a part of dust, but its filter effect is undesirable.And such screen pack is bored a hole easily, the life-span short.
The utility model content
The utility model technical issues that need to address, promptly the purpose of this utility model is for a kind of vavuum pump filter is provided.A kind of vavuum pump filter of this kind can make the air that enters vavuum pump obtain filtering, and makes the vavuum pump can be more durable.
Technical problem of the present utility model can solve by taking following measure:
A kind of vavuum pump filter, its design feature is: comprise filter body, filter core and outlet nozzle, filter body, outlet nozzle hollow; The left end of filter body and the right-hand member of outlet nozzle are provided with connecting thread, and the right-hand member of filter body is connected with the left end detachable type of outlet nozzle, and described outlet nozzle is provided with O-ring seal with the junction of filter body; Filter core is positioned at the inner chamber of filter body, and outlet nozzle is by being connected the inner chamber that filter core is fixed in the filter body with the filter body.
The utility model technical problem, can also take following measure to solve:
Aforesaid filter core is that frustoconical, its cross-sectional shape are trapezoidal.
Be provided with bulge loop and gasket ring in the inner chamber of aforesaid filter body, bulge loop is one-body molded with the filter intracoelomic cavity, and outlet nozzle is fixed in filter core in the filter intracoelomic cavity by gasket ring and bulge loop.
The connecting thread of the left end of aforesaid filter body is an internal thread, and a sealing ring is located at the right-hand member of described internal thread.
The utlity model has following beneficial effect:
1, the utility model can be connected in the air inlet place of vavuum pump, make vavuum pump when work, the air that enters vavuum pump obtains the filtration of filter, thereby airborne dust, small foreign body can not enter vavuum pump, the life-span of vavuum pump can be improved, and the repair rate of product can be reduced.
2, the right-hand member of filter body of the present utility model is connected with the left end detachable type of outlet nozzle, when outlet nozzle is connected with the filter body filter core is fixed in the inner chamber of filter body, make the utility model mounting or dismounting easily, in the time will cleaning filter core, as long as outlet nozzle and filter body are separated, promptly filter core can be taken out and carry out the impurity cleaning.
3, the cross section of filter core of the present utility model is trapezoidal, can make filter core have more filter table area, helps strengthening the filtering function of filter core, avoids filter core to stop up easily.
4, the utility model is simple in structure, and is easy to manufacture.
