Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 3 and 4, a manually controllable oil-gas mixing block comprises a mixing block body 1, a compressed gas passage 2, an oil inlet passage 3, an oil return passage 4 and an oil-gas passage 5 are arranged in the mixing block body 1, a hole E6 is further arranged in the mixing block body 1, the hole E6 is communicated with the oil inlet passage 3 and the oil-gas passage 5, a manual reversing mechanism is arranged in the oil inlet passage 3, the manual reversing mechanism comprises a reversing piston 7, a seal seat 8 and a reversing handle 9, the seal seat 8 is fixedly connected with the mixing block body 1, the lower end of the reversing piston 7 penetrates through the seal seat 8 and is matched with the oil inlet passage 3, the upper end of the reversing piston 7 is connected with the reversing handle 9, a hole a10 is arranged in the center of the lower portion of the reversing piston 7, a hole B11 and a hole D12 are respectively formed outwards in the diameter direction of the hole a10, and the oil return passage 4.

Through threaded connection between seal receptacle 8 and the mixing block body 1, and seal receptacle 8 and mixing block body 1 between sealed through sealed 13, the hole of seal receptacle 8 is seted up flutedly, seals through sealing washer 14 between the recess of switching-over piston 7 and seal receptacle 8. Can make and reach sealed effect between seal receptacle 8 and mixing piece body 1, the switching-over piston 7, effectively prevent to appear leaking outward or interior hourglass.

The hole B11 and the hole D12 form an included angle of 90 degrees in the diameter direction, and the direction of the reversing handle 9 is consistent with the direction of the hole D12. When the oil supply state needs to be adjusted, the directions of the hole B11 and the hole D12 can be adjusted by directly manually adjusting the direction of the reversing handle 9, so that the oil supply state is controlled.

The outlet of hole E6 is equipped with check valve 15, because of the lubricating oil supplies for the clearance in the oil-gas lubrication, can ensure after increasing check valve 15 that when not supplying oil, compressed air can not get into in the oil feed passageway 3.

As shown in fig. 3 and 5, in the oil supply state, the direction of the direction changing handle 9 is first adjusted so that the hole D12 communicates with the hole E6 and the hole B11 is disconnected from the hole C18. Lubricating oil enters the oil inlet channel 3 from the oil inlet one-way joint 16 and then sequentially enters the hole A10, the hole B11 and the hole D12 on the reversing piston 7 in the oil inlet channel 3. At this time, since the hole D12 is communicated with the hole E6, the lubricating oil flows into the hole E6 through the hole D12, and then pushes against the check valve 15 at the outlet of the hole E6 to enter the oil-air passage 5. Under the action of compressed air, the lubricating oil forms an oil-gas two-phase medium and is conveyed out from an oil-gas outlet 17 of the oil-gas channel 5. At this time, since the space between the hole B11 and the hole C18 is sealed by the selector piston 7, the oil return passage 4 and the oil inlet passage 3 are disconnected from each other. Thus, oil supply to the equipment is achieved.

As shown in fig. 4 and 5, when the oil supply needs to be cut off, the direction changing handle 9 is rotated by 90 degrees to connect the hole B11 with the hole C18 and disconnect the hole D12 from the hole E6. Lubricating oil enters the oil inlet channel 3 from the oil inlet one-way joint 16 and then sequentially enters the hole A10, the hole B11 and the hole D12 on the reversing piston 7 in the oil inlet channel 3. At this time, the oil-gas passage 5 and the oil-intake passage 3 are in a disconnected state because the space between the hole D12 and the hole E6 is sealed by the selector piston 7. The hole B11 is communicated with the hole C18, and the lubricating oil flows into the hole C18 through the hole B11, flows into the oil return passage 4, and finally flows back to the oil supply main station 20 through the oil return line 19. Thus, the oil supply to the equipment is suspended. When oil supply is needed to be continued, the direction of the reversing handle 9 is adjusted again.

The utility model discloses under the condition that does not change oil-gas mixing piece overall dimension, increase manual reversing mechanism in the oil feed passageway in the oil-gas mixing piece, can realize the control to the oil circuit. Novel design, overall structure are compact, convenient operation, good reliability, effective reduce cost.
