[0028] Example 1

[0029] like Figure 1-Figure 6 As shown, this embodiment proposes an instrument valve group for oil pipelines, including a valve body 1 and a filter box 14, the internal thread of the valve body 1 is rotatably installed with a lifting threaded rod 5, the top of the lifting threaded rod 5 is welded with a handle 4, the two sides of the valve body 1 are respectively welded with an oil inlet connection port 2 and an oil outlet connection port 3, the inside of the valve body 1 is respectively installed with an oil outlet pipeline 7 and an oil inlet pipeline 6, a filter screen 10 is fixedly connected to one side of the filter box 14 by screws, the inside of the filter box 14 is respectively rotatably installed with a rotating shaft 16, a driving shaft 24 and a driven shaft 18, a driven bevel gear 23 is fixedly sleeved on the outer circumference of the driven shaft 18, a synchronous belt 19 is fixedly sleeved on the outer circumference of the rotating shaft 16 and the driven shaft 18, a turntable 13 is rotatably installed on the outer circumference of the rotating shaft 16, and the turntable A sliding block 25 is fixedly connected to one side of 13 by screws, a fan blade 15 is fixedly sleeved on the outer circumference of the driving shaft 24, a driving bevel gear 22 is welded to one end of the driving shaft 24, two support rods 9 are welded inside the filter box 14, and a sliding rod 20 is slidably assembled on the outer circumference of the two support rods 9, and a cleaning rod 21 is welded to one end of the sliding rod 20. The fan blade 15 is rotated by the flow thrust of the oil, thereby driving the driving bevel gear 22 and the driven bevel gear 23 to rotate, and then the driven shaft 18 drives the turntable 13 to rotate through the synchronous belt 19. The sliding block 25 on the turntable 13 drives the sliding rod 20 and the cleaning rod 21 to reciprocate when the turntable 13 rotates, so that the cleaning rod 21 continuously cleans the filter screen 10 to prevent clogging.

[0030] like Figure 3-Figure 6 As shown, support holes are provided at both ends of the slide rod 20, and two support rods 9 pass through the inside of the two support holes respectively.

[0031] like Figure 3-Figure 5 As shown, a hole ring is opened on the partition plate 11, and the driving shaft 24 passes through the inside of the hole ring, and the driving bevel gear 22 and the driven bevel gear 23 are meshed.

[0032] like Figure 3-Figure 6 As shown, a slide groove is provided on the slide rod 20, and the slide block 25 is located inside the slide groove.

[0033] like Figure 3-Figure 6 As shown, synchronous wheels 17 are fixedly sleeved on the outer circumferences of the rotating shaft 16 and the driven shaft 18 , and synchronous belts 19 are installed together on the outer circumferences of the two synchronous wheels 17 .

[0035] The specific implementation principle of this embodiment is as follows: the connecting flange and the fixing plate are fixedly connected by connecting screws. After the valve body and the fixing plate are connected, oil starts to flow into the oil inlet connection port, and the oil to be transported starts to flow in the oil inlet pipe. After the handle is turned, the lifting threaded rod starts to rotate, thereby driving the valve plate to rise, and the oil flows into the oil outlet pipe through the flow hole. The oil passes through the fan blades in the pipe, and the flow pressure difference of the oil itself increases the flow rate, thereby driving the fan blades to rotate. The active bevel gear and the driven bevel gear at one end of the fan blade are meshed, and then the active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the driven shaft to rotate. Due to the setting of the synchronous belt, the rotating shaft rotates synchronously, so that the turntable rotates clockwise, and the sliding block on one side of the turntable reciprocates on the sliding rod, and at the same time the sliding rod reciprocates on the rotating shaft, so that the sliding rod drives the cleaning rod to reciprocate on the filter net to continuously clean it.

[0036] Example 2

[0037] like Figure 3-Figure 6 As shown, this embodiment also introduces an instrument valve group for oil pipelines, which adds the following structure on the basis of the first embodiment: the inside of the filter box 14 is fixedly connected with a cover plate 12 by screws, and a partition plate 11 is welded on one side of the cover plate 12. Through the arrangement of the filter box 14, the partition plate 11 and other structures, the filter device is completely protected to prevent external factors from damaging the internal device. The partition plate 11 protects the active bevel gear 22 and the driven bevel gear 23, and the cover plate 12 protects the synchronous belt 19 and the turntable 13, thereby extending the service life of the entire filter cleaning device.

[0038] The specific implementation principle of this embodiment is as follows: after the filter screen and the filter box are connected by screws, the filter box protects the cleaning device, and the filter box is fixed on the partition and the cover plate to make the filter box more stable. The cleaning device starts to work, and the filter screen starts to filter impurities. Conversely, the filter screen and the filter box can be separated by removing the screws, and then the disassembled filter screen can be cleaned.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
