As the preferred scheme of one, above cover the exhaust port being provided with and being communicated with filtering cavity, in exhaust port, be equipped with bleed valve.
As the preferred scheme of one, described filter body is aluminum alloy filter body, and described upper cover is aluminum alloy upper cover.
As the preferred scheme of one, filter body is provided with drain oil at filtering cavity bottom position place, in drain oil, is provided with nut of draining the oil.
As the preferred scheme of one, be provided with the threaded lining of draining the oil of inner processing in drain oil, nut of draining the oil is connected by thread seal with lining of draining the oil.
The beneficial effects of the utility model are: filter owing to have employed papery filter screen, can by all filterings of trickle impurity, and the oil product impurity content after filter is few.Owing to adopting oil-feed in oil-feed axle, the mode of from inside to outside filtering from papery filter screen again carrys out filter fuel, make whole filter constructions compact, and be convenient to control feed liquor speed, avoid fluid inlet excessive velocities impact papery filter screen and shorten the filter screen life-span.
On cover the exhaust port being provided with and being communicated with filtering cavity, be equipped with bleed valve in exhaust port, if be convenient to after filter inner accumulated gas discharge, ensure the normal safe work of filter.
Because filter body is aluminum alloy filter body, upper cover is aluminum alloy upper cover, makes whole filter quality less, is convenient to installation and removal.
Filter body is provided with drain oil at filtering cavity bottom position place, in drain oil, is provided with nut of draining the oil, by the oily emptying in filtering cavity when being convenient to dismantle filter.
The threaded lining of draining the oil of inner processing is provided with in drain oil, nut of draining the oil is connected by thread seal with lining of draining the oil, on the one hand, be convenient to after damaging change, on the other hand, lining of draining the oil can be processed with the material that hardness is larger, even if nut of draining the oil like this is dismantled repeatedly, the thread of draining the oil on lining is not easy to wear yet.
