Abstract
The utility model discloses a take hydraulic oil filter of bypass, it includes a hydraulic oil filter, it has the inner frame to support on the filter screen inner wall of filter, install the bypass valve in the port on the upper end cover mesopore of inner frame, install the poor controlled shutdown's of an oil pressure elasticity lid in the inlet of bypass valve, upwards there is an oil return filter core with step mount in the bottom end cover mesopore of inner frame, install the sealing washer on the bottom end cover centre bore inner wall of inner frame, install a handle on the upper end cover, on the oil return filter core, install one down on the port respectively and take mesoporous the annular clamped lid. The utility model discloses oil return filter core of installation in current hydraulic oil filter filter screen skeleton makes the oil return also obtain filtering, has avoided the interior impurity of fluid to hydraulic system secondary pollution effectively, guarantees the normal work under the filter screen jam condition.
Description
Technical field:
This utility model relates to filter, the hydraulic oil filter of a kind of band bypass installed and used be applicable to hydraulic system.
Background technology:
The hydraulic oil filter of the band bypass used in hydraulic system at present, is all one bypass valve of installation in the upper end cover mesopore of a filter screen inner frame, and the lower end of bypass valve connects with fuel tank through inner frame mesopore.This filter is when there is gambling plug in filter element, in system, pressure raises, bypass valve is made under high pressure to automatically open up, fluid directly enters fuel tank through bypass valve and filter screen inner frame, the fluid through filtering is not directly entered fuel tank without filtration, impurity in fluid can cause secondary pollution to hydraulic system, as changed filter screen not in time, then can affect the normal work of hydraulic system.
Summary of the invention:
The purpose of this utility model is to provide one and prevents oil return to hydraulic system secondary pollution, reduces the hydraulic oil filter of the band bypass changing filter screen number of times.
The technical solution of the utility model completes as follows, a kind of hydraulic oil filter of band bypass, it includes a hydraulic oil filter, it is characterized in that: supporting on filter screen 3 inwall of filter has inner frame, in the upper end cover mesopore upper port of inner frame, bypass valve is installed, the elastomeric cap that one oil pressure difference controls to close is installed in the inlet of bypass valve, in the bottom end cover mesopore of inner frame, upwards with step, one oil return filter element is installed, the bottom end cover center bore inner wall of inner frame is provided with sealing ring, upper end cover is provided with a handle, upper port at oil return filter element is provided with the fixing lid of a ring packing, lower port is provided with the fixing lid of a circular middle hole.Oil return filter element inwall is provided with an oil return frame of filter element between fixing lid up and down.The filtering accuracy of oil return filter element is coarser than the filtering accuracy of strainer screen.
This utility model installs an oil return filter element in existing hydraulic oil filter filter screen skeleton, and the oil return fluid making bypass valve open also is filtered, and in efficiently avoid fluid, impurity is to hydraulic system secondary pollution, it is ensured that the normal work in the case of filter net jam.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Embodiment is described in detail in conjunction with accompanying drawing, it includes a hydraulic oil filter, filter screen 3 inwall of filter supports and has inner frame 4, in the upper end cover 2 mesopore upper port of inner frame, bypass valve 11 is installed, the elastomeric cap 12 that one oil pressure difference controls to close is installed in the inlet of bypass valve, in bottom end cover 5 mesopore of inner frame, upwards with step, one oil return filter element 8 is installed, the bottom end cover center bore inner wall of inner frame is provided with sealing ring 6, upper end cover is provided with a handle 1, upper port at oil return filter element is provided with a ring packing and fixes lid 10, lower port is provided with a circular middle hole and fixes lid 7.Oil return filter element inwall is provided with an oil return frame of filter element 9 between fixing lid up and down.The filtering accuracy of oil return filter element is coarser than the filtering accuracy of strainer screen.In work, after the filter screen of filter is blocked by the magazine in fluid, defecator internal pressure increases, when pressure reduction arrives setting value, the elastomeric cap in bypass valve automatically turns on, fluid directly flows into fuel tank after oil return filter element filtering, for hydraulic pressure system worked well, fluid secondary pollution can be prevented effectively from, and ensure the normal work of filter.
Claims (3)
