[0030] The surface of the card rod 602 is sleeved with a first spring 603, the bottom surface of the first spring 603 is fixedly connected to the sleeve 601, the top surface of the first spring 603 is fixedly connected to the slide 604, both sides of the slide 604 are fitted and connected to the sleeve 601, the slide 604 is connected to the card rod 602, the connecting sleeve 11 is sleeved and connected to the connecting rod 9, the surface of the connecting sleeve 11 away from the filter screen 7 is penetrated and connected with a rotating plate 12, and the rotating plate 12 is penetrated and connected to the connecting rod 9, as shown in FIG. Figure 4 As shown, by pulling the card rod 602, the movement of the card rod 602 can drive the movement of the slide 604. The movement of the slide 604 squeezes the first spring 603, causing the first spring 603 to deform. At the same time, after the card rod 602 is pulled to a certain position, the card rod 602 is separated from the card slot 17, so that by rotating the rotating plate 12, the rotating plate 12 can drive the rotation of the connecting sleeve 11. The rotation of the connecting sleeve 11 can drive the rotation of the baffle 10, so that the baffle 10 can adjust the number of holes on the filter 7, thereby controlling and adjusting the flow rate of natural gas through the filter 7. At the same time, the first spring 603 is a compression spring in the prior art.

[0031] The sealing gasket 4 is symmetrically mounted with a snap-fit ​​block 13 on one side surface close to the body 1, and a through groove 14 is provided on the side surface of the snap-fit ​​block 13 away from the sealing gasket 4. A limit rod 15 is connected through the inside of the through groove 14, and a second spring 16 is sleeved on the side surface close to the top of the limit rod 15. The top surface of the second spring 16 is fixedly connected to the limit rod 15, and the bottom surface of the second spring 16 is fixedly connected to the body 1. Figure 3 As shown, by pulling the limit rod 15 to completely separate the limit rod 15 from the through groove 14, the sealing gasket 4 can be pulled to separate the sealing gasket 4 from one side of the main body 1, so that the filter screen 7 and the baffle 10 can be separated from the main body 1, so that the filter screen 7 and the baffle 10 can be cleaned.

[0032] The connecting sleeve 11 is provided with a plurality of slots 17 on one side of the surface close to the rotating plate 12. The slots 17 are engaged with the clamping rod 602.

Then, by loosening the limiting rod 15, the limiting rod 15 is lowered under the action of the second spring 16, so that the limiting rod 15 is connected with the through groove 14, so that the limiting rod 15 can limit the locking block 13, thereby achieving the effect of limiting the sealing gasket 4, so that it is more convenient to clean the filter screen 7 and the baffle 10, and the second spring 16 is a tension spring in the prior art.

[0034] Working principle: Before using this adjustable natural gas filter, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5 As shown, first, when the baffle 10 needs to be adjusted, the movement of the card rod 602 can drive the movement of the slide 604 by pulling the card rod 602, and the movement of the slide 604 will squeeze the first spring 603, so that the first spring 603 is deformed. At the same time, after the card rod 602 is pulled to a certain position, the card rod 602 is separated from the card slot 17, so that the rotating plate 12 can be rotated to drive the rotation of the connecting sleeve 11, and the rotation of the connecting sleeve 11 can drive the rotation of the baffle 10, so that the baffle 10 can adjust the number of holes on the filter 7, thereby controlling and adjusting the flow rate of natural gas through the filter 7. After the baffle 10 is rotated to the appropriate position, by loosening the clamping rod 602, the first spring 603, through its own characteristics, causes the first spring 603 to squeeze the slide plate 604, thereby returning the slide plate 604 to its original position. At the same time, the slide plate 604 and the clamping rod 602 are fixedly connected through, so that the movement of the slide plate 604 can drive the movement of the clamping rod 602, so that the slide plate 604 drives the clamping rod 602 to return to its original position, so that the clamping rod 602 is engaged with the clamping groove 17, so that the connecting sleeve 11 can be limited, so that the adjustment effect can be achieved, and at the same time, the baffle 10 can also help to achieve uniform distribution of natural gas during filtration, avoiding uneven filtration problems caused by local flow rates being too fast or too slow.

[0035] When the filter screen 7 and the baffle plate 10 are to be cleaned, the filter screen 7 and the baffle plate 10 are to be separated from each other by pulling the limiting rod 15 so as to completely separate the limiting rod 15 from the through groove 14. Then, the sealing gasket 4 can be separated from one side of the body 1 by pulling the sealing gasket 4, so that the filter screen 7 and the baffle plate 10 can be separated from the body 1, thereby making it possible to clean the filter screen 7 and the baffle plate 10. At the same time, when installing, after the filter screen 7 and the baffle plate 10 are placed inside the body 1, the snapping block 13 on the sealing gasket 4 is snapped with the snapping groove 18 on the body 1, so that the sealing gasket 4 is tightly fitted with the body 1, the limiting rod 15 is loosened, so that the limiting rod 15 is lowered under the action of the second spring 16, so that the limiting rod 15 is connected with the through groove 14, so that the limiting rod 15 can limit the snapping block 13, thereby achieving the effect of limiting the sealing gasket 4, making it more convenient to clean the filter screen 7 and the baffle plate 10.
