Work as filter element（4）When blocking to a certain extent, the filter capacity of filter core declines, the oil return back of the body in outside in filter core
Pressure increase, when reaching alarm switch（1）Setting value when, alarm switch（1）Alarm, should now change filter core in time.If filter
Core（4）Further block, bypass valve head（11）Case of by-pass valve will be compressed in the presence of return pressure（10）, now by-passing valve
Open, the pressure oil of blocking is largely directly over filter core（4）With by-passing valve oil return box, because this filter filtering traffic is big,
So by-passing valve used is to form parallel bypass valve group by three independent by-passing valves, bypass flow is big, is installed in parallel in support
Plate（12）On.
When changing filter core, lid is pulled down（2）Take out filter core（4）, now filter core（4）Supporting plate can not be withstood（12）,
Outer guide type Self-sealing valve（5）In 4 back-moving springs（9）In the presence of it is rapid close Self-sealing valve, ensure that fluid is not revealed, Self-sealing valve
By 4 outer guide blots limitations, only remain the one degree of freedom of axial translation, in the absence of rotary freedom and it is other cause from
The free degree of valve dislocation translation is sealed, so self-styled safe and reliable；As a result of four back-moving springs, so each spring
Rigidity is not required to that rapid self-styled requirement can be met very much greatly, and self-styled effect is not interfered with yet even if wherein one or two failure
Fruit, further increase reliability.
Thus, the present invention realizes the oil return filter of the new Self-sealing valve of big flow band of fuel tank side installation top oil return opening
Device, realizes the filtering requirement of large-tonnage mine car large-flow hydraulic system oil return, at the same be easy to hydraulic system element installation and
The layout of return line, system oil return back pressure is advantageously reduced, improve system bulk life time and reliability.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
