And the two channels which are communicated can be realized only through the intersection of the hole structures, a pipe joint is not required, and the oil duct connecting structure is simplified.
In addition, the valve body 1 can also provide protection for various passages, valves, etc. located inside.

That is, at the same time, only one filtering passage 12 is connected between the oil inlet passage 11 and the oil outlet passage 13 to filter the oil passing through the oil path, remove impurities in the oil, and clean oil is led to the gear box through the oil outlet passage 13 and lubricates and cools gears, bearings and the like in the gear box.
When one of the filters 3 fails, the filter channel 12 where the failed filter 3 is located is disconnected by the on-off component, and the filter channel 12 where the other filter 3 is located is simultaneously communicated, and then the failed filter 3 can be maintained, detached, replaced and the like, in the process, that is, when the failed filter 3 is maintained and replaced, the compressor is not required to be stopped, clean oil can be still provided for the gear box, normal operation of the system is ensured, and thus, the economic loss caused by stopping can be avoided. Further, since the failed filter 3 is disconnected from the oil passage by the on-off member, maintenance and replacement operations performed on the filter 3 are completely independent of the operation state of the compressor, and flexibility is improved.
The outlet side of each filter 3 is provided with a one-way valve, and the flow direction of the one-way valve is from the filtering passage 12 to one side of the oil outlet passage 13, so that the oil backflow is avoided, and therefore, the on-off piece can only be used for controlling the on-off between each filter 3 and the oil inlet passage 11.

So arranged, it is convenient to arrange the channels in the valve body 1.
The on-off parts comprise a driving part 21 and a circular arc baffle 22, two filtering channels 12 are arranged, only one circular arc baffle 22 is arranged, the first section 112 and the second section 113 are coaxially arranged, a circular arc slideway is arranged at the communication part among the inlet section 111, the first section 112 and the second section 113, the driving part 21 can drive the circular arc baffle 22 to rotate along the circular arc slideway, so that the circular arc baffle 22 rotates to a first position 41 and a second position 42, when the circular arc baffle 22 rotates to the first position 41, as shown in fig. 4, the circular arc baffle 22 can block the first section 112, and when the circular arc baffle 22 rotates to the second position 42, the circular arc baffle 22 can block the second section 113.
Of course, the driving member 21 may also be capable of moving along a straight line to switch between the two filtering passages 12, such as the blocking member being capable of separating from the second section 113 and blocking the first section 112 when moving into the first section 112, and separating from the first section 112 and blocking the second section 113 when moving into the second section 113. Alternatively, in this embodiment, the two filter passages 12 may be separately controlled to be opened or closed by two opening or closing members, for example, the opening or closing members are configured like a shutter, and when the shutter is inserted into the filter passage 12, the shutter can block the filter passage 12.
And when the on-off of the two filtering channels 12 is switched by the arc-shaped baffle 22, the whole structure can be simplified, and the operation is convenient. In addition, the driving piece 21 drives the circular arc-shaped baffle plate 22 to rotate, so that when the two filtering channels 12 are switched, the movement stroke of the circular arc-shaped baffle plate 22 can be reduced, the space requirement in the valve body 1 is reduced, and the whole volume is reduced. Moreover, the circular arc-shaped baffle 22 is driven to rotate by the driving piece 21, so that compared with the case that the driving piece 21 drives the baffle to move along a straight line, the action force of oil liquid flowing is not needed to be overcome, and the operation is more labor-saving.
The driving member 21 is a manual operation member arranged on the outer wall of the valve body 1, and the manual operation member can be a wrench or a hand wheel, so that the operation of operators is convenient.
The outer wall of the valve body 1 is further provided with an index plate 5, the index plate 5 is provided with prompt marks, such as a first scale and a second scale, the manual operation member is provided with an indication structure, when the manual operation member rotates to the indication structure corresponds to the first scale, the arc-shaped baffle 22 is located at the first position 41 and seals the first section 112, and when the manual operation member rotates to the indication structure corresponds to the second scale, the arc-shaped baffle 22 is located at the second position 42 and seals the second section 113.
The index plate 5 is arranged, so that operators can conveniently know the position of the circular arc-shaped baffle 22, and after switching, one filter channel 12 is communicated with the oil inlet channel 11, and the other filter channel 12 is disconnected with the oil inlet channel 11.
Specifically, the setting of the indication mark of the index plate 5 is not limited, and may be a scale, such as two scales of 0 ° and 180 ° or all scales of 0 ° -180 °, or a text mark, such as a word of "filter a" and "filter B", etc. The indication structure can be a protrusion, a notch, a line drawing and the like on the surface of the manual operation piece.

As shown in fig. 6, the filter passage 12 includes a pre-filter passage 121, an inlet filter passage 122 and an outlet filter passage 123 which are sequentially communicated between the inlet passage 11 and the outlet passage 13, wherein the pre-filter passage 121 is communicated with the first section 112 or the second section 113, and the filter 3 is communicated between the inlet filter passage 122 and the outlet filter passage 123, so that the arrangement of the passages in the valve body 1 can be facilitated.
And, as shown in fig. 6, a bypass valve 10 is further disposed between the pre-filter passage 121 and the oil outlet passage 13, the bypass valve 10 is disposed in parallel with the filter 3, when the pressure difference between the pre-filter passage 121 and the oil outlet passage 13 exceeds a preset pressure difference value, it is indicated that the filter 3 is blocked, the bypass valve 10 is opened, and when the pressure difference between the pre-filter passage 121 and the oil outlet passage 13 does not exceed the preset pressure difference value, it is indicated that the filter 3 is working normally, the bypass valve 10 is closed.
Under normal working conditions of the compressor, the pressure of the pre-filtering channel 121 and the pressure of the oil outlet channel 13 are the same or the pressure difference is smaller than a preset pressure difference value, oil is filtered by the filter 3 and then is introduced into the gear box, if the filter 3 is blocked and other faults occur, the pressure of the oil inlet side of the filter 3 is larger and larger, the pressure of the oil outlet side is smaller, namely the pressure in the pre-filtering channel 121 is increased, the pressure difference between the pre-filtering channel 121 and the oil outlet channel 13 is increased, when the pressure difference exceeds the preset pressure difference value, the bypass valve 10 is opened, so that at least part of the oil in the pre-filtering channel 121 can reach the oil outlet channel 13 through the bypass valve 10, and enters the gear box to lubricate and cool gears, bearings and the like in the gear box, and the situation that the gears are worn due to the fact that the oil cannot be supplied to the gear box when the filter 3 is blocked and the faults are avoided.
After the operator disconnects the filter channel 12 where the failed filter 3 is located by the on-off member, the pressure difference between the pre-filter channel 121 and the oil outlet channel 13 in this channel falls below the preset pressure difference, and the bypass valve 10 is closed.
