Stretch into inside the oil pocket, the filter core is provided with O-ring seals with the raised and filter seat inner bottom wall contact site.
Using above structure, step is set in cartridge filter bottom, cunning is taken in step and the closed annular space of filter seat
Ring seal is combined, and is combined by both U sealing rings and square seal ring, makes both inwalls and filtering respectively with filter seat
Drum outer wall patch it is tighter, increase sealable area so that better seal contact surface between the two, while filter core with it is described
Raised and filter seat inner bottom wall contact site is provided with O-ring seals, will be sufficiently sealed between filter core and projection.
As preferred：The cartridge filter has containing second step on its top that section is threadedly coupled with filter seat,
External screw thread is provided with the second step, and is set with fastening screw nut.Using above structure, by second step and filter
Engaging can further increase sealing effectiveness, while being arranged fastening screw nut on top, cartridge filter and filter seat connection can be made tighter,
Prevent loosening from causing poorly sealed reality.
As preferred：The projection is provided with oil duct, and oil duct one end oil pocket connection, the other end connects with the oil inlet
It is logical.Using above structure, hydraulic oil enters through oil inlet, and oil pocket is entered along oil duct, because the upper end of projection is higher than the bottom of filter core
Portion, then improve equivalent to by oil inlet, it is ensured that the hydraulic oil high of entrance can again flow out after the filtering of one end filter core.
As preferred：Connected using fine thread between the cartridge filter and filter seat.Using above structure, can improve
The sealability of threaded connection place between cartridge filter and filter seat, prevents oil leak pressure release.
Compared with prior art, the beneficial effects of the utility model are：
The voltage regulation type super high pressure bend pipe filter that the utility model is provided, changes the cartridge filter and filter of conventional filter
The usual mode directly fitted of surface between seat, step is arranged to by by filter cylinder bottom, make step surface and with filter seat
Inwall is contacted, while being installed by U-shaped sealing ring and matched side in the closed cell that step and filter inwall are formed
The slip-ring seal combination of shape sealing ring composition, increased the area of sealing and the adaptive faculty of seal combination, so as to play more preferably
Sealing function, while filter core is provided with O-ring seals with described raised and filter seat inner bottom wall contact site, can also enter one
Step plays sealing function to device, and simple structure improves the sealing property of filter, it is ensured that oil circuit pressure is normal.
Brief description of the drawings
Fig. 1 is the sectional view of the embodiment of the utility model one；
Fig. 2 is partial enlarged drawing at A in Fig. 1.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
