Utility model content

The oil absorption filter that the purpose of this utility model is to provide a kind of good sealing effect, sealing property is stable.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of oil absorption filter, including housing, the circular filter core of the both ends open being arranged in housing, closure bypass valve on filter element opening, wherein: described bypass valve includes valve seat and the sealing label flap on valve seat, described inner walls projection has fixed structure, and valve seat is pressed on filter element by described fixed structure, keeps valve seat and filter element closely connected.

By adopting technique scheme, using bypass valve mainly to block all at filter element in the filter, bypass valve is used for pressure release. And utilize fixed structure to keep the closing laminating between valve seat and filter element, it is ensured that the sealing effectiveness between valve seat and filter element, it is to avoid separate because of the reason such as external force, loss between valve seat with filter element.

This utility model is further arranged to: described shell end has open ports, and this open ports is covered with capping, and described fixed structure is arranged on capping inboard.

By adopting technique scheme, the design of capping facilitates the installation of bypass valve, also simplify the processing of fixed structure simultaneously.

This utility model is further arranged to: the edge of described open ports is provided with ring flange, and described capping and ring flange are bolted to connection.

By adopting technique scheme, both facilitate the installation of capping, bypass valve, also strengthen the bonding strength between capping and housing simultaneously.

This utility model is further arranged to: described valve cup rim is raised with in the horizontal direction and picks up the ears, described fixed structure and pick up the ears conflict.

By adopting technique scheme, utilizing and pick up the ears to replace valve seat body and fixed structure to conflict, and pick up the ears to be positioned at outside valve seat, fixed structure is conflicted and can be kept the closely connected of valve seat and filter element on picking up the ears more smoothly, it is to avoid valve seat inclination and offset.

This utility model is further arranged to: described in pick up the ears to be provided with multiple, and be evenly distributed in valve seat circumference.

By adopt technique scheme, it is ensured that pick up the ears with between fixed structure steady, effectively contact.

This utility model is further arranged to: described fixed structure is the bulge loop being wholely set with capping.

By adopting technique scheme, strengthen the intensity of fixed structure, it is ensured that fixed structure can effectively push down valve seat.

Compared with prior art, this utility model has the advantage such as bypass valve convenient disassembly, fixing effectively, the good airproof performance of capping.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by patent protection in right of the present utility model.

Embodiment 1: a kind of oil absorption filter, including housing 1, the circular filter core 2 of the both ends open being arranged in housing 1, closure bypass valve 3 on filter element 2 opening, housing 1 lower end is provided with oil-in 16, the inside UNICOM of this oil-in 16 and filter element 2, at housing 1, upper end position is provided with oil-out 10, the outside UNICOM of this oil-out 10 and filter element 2, fluid enters in filter element 2 from oil-in 16, and filtered to filter element 2 by filter element 2, finally flow out from oil-out 10. Referring to Figure of description 3, described bypass valve 3 includes valve seat 4 and the sealing label flap 5 on valve seat 4, on flap 5, center is provided with vertical pull bar 7, and pull bar 7 one end is fixed on flap 5 by fixing nut 14, and the other end stretches in filter element 2, aluminum bar is arranged with spring 6, this spring 6 is utilized to keep flap 5 to be closely attached on valve seat 4, when in filter element 2, hydraulic pressure is excessive, fluid extruding flap 5, compression spring 6, and then open bypass valve 3, directly from the opening part of filter element 2 to oil-out 10.
