Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to an adaptive Y-type filter. Background Technology

[0002] The working principle of a Y-type filter is mainly to filter out impurities in the medium through a filter screen to protect the normal operation of downstream equipment. When liquid enters the filter basket through the main pipe, solid impurity particles are blocked inside the filter basket, while clean fluid passes through the filter basket and is discharged from the filter outlet.

[0003] However, the following drawbacks still exist: most existing Y-type filters have a fixed water output. Due to the fixed water output, it is not convenient for staff to adjust the water output according to usage needs, which affects the normal operation of the equipment. This limits the application range of Y-type filters and makes it difficult to adapt to various complex needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adaptive filter cartridge type Y-type filter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adaptive Y-type filter cartridge includes a side housing with openings at both ends, an inlet pipe, and an outlet pipe. The inlet pipe is fixedly connected to one side of the side housing, and the outlet pipe is fixedly connected to one side of the side housing and communicates with the interior of the side housing, forming a Y-shaped structure. A filter cartridge is provided inside the side housing, and a sliding plate is provided inside the side housing and fixed to the filter cartridge. A support assembly for supporting the filter cartridge is provided inside the inlet pipe. A mounting hole is provided on the top of the sliding plate, and a connecting post is fixedly connected to the mounting hole. A push plate is slidably connected to the outside of the connecting post, and a sealing gasket that fits against the filter cartridge is fixedly connected to the outside of the push plate. A second spring is sleeved on the outside of the connecting post, and the two ends of the second spring are fixed to the push plate and the sliding plate, respectively. A locking assembly for fixing the filter cartridge is provided on the top of the side housing.

[0007] As a further embodiment of this utility model, the support assembly includes a support ring, which is fixedly connected inside the water inlet pipe near the side shell. A U-shaped groove is provided on the top of the support ring, and the filter cartridge is inserted into the U-shaped groove.

[0008] As a further embodiment of this utility model, the locking assembly includes a fixing ring, which is fixedly connected to the top of the side housing. A top cover is provided inside the fixing ring. The connecting post passes through the top cover and is fixed to the top cover. A connecting block is fixedly connected to the top of the connecting post. Multiple insertion holes are provided on the outer circumference of the connecting block. Two symmetrically distributed fixing rods are fixedly connected to the top of the fixing ring. A telescopic rod is fixedly connected to one side of the fixing rod. An insertion block is fixedly connected to one end of the telescopic rod, and the insertion block is inserted into the insertion hole.

[0009] As a further embodiment of this utility model, a first spring is sleeved on the outer side of the telescopic rod, and the two ends of the first spring are respectively fixed to the insert block and the fixing rod.

[0010] As a further embodiment of this utility model, a limiting block that blocks the push plate is fixedly connected to one side of the connecting column located inside the side housing.

[0011] As a further embodiment of this utility model, flanges are fixedly connected to one end of the inlet pipe and the outlet pipe on opposite sides.

[0012] As a further improvement of this invention, a sealing ring is fixedly connected to one side of the flange.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the combined use of the push plate and the second spring, when water flows in through the inlet pipe, the water pressure pushes the push plate to move along the connecting column. The push plate compresses the second spring. When the water pressure equals the elastic force of the second spring, the push plate will remain in its moving position. Since the exposed part of the push plate is located at the filter cartridge in the outlet pipe, the water will pass through the filter cartridge and be discharged from the outlet pipe. When the water pressure increases, the position of the push plate will change, exposing more filter holes and increasing the water output. Thus, the water output can be adaptively adjusted according to the water pressure, which is convenient for the use of Y-type filters and improves the applicability of Y-type filters.

[0015] 2. The locking component secures the filter cartridge, making it easy for staff to disassemble and clean it after prolonged use, thus improving the convenience of cleaning the Y-type filter. Attached Figure Description

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0021] Reference Figures 1-3An adaptive Y-type filter cartridge includes a side housing 2 with openings at both ends, an inlet pipe 3, and an outlet pipe 6. The inlet pipe 3 is welded to one side of the side housing 2, and the outlet pipe 6 is welded to one side of the side housing 2 and communicates with the interior of the side housing 2, forming a Y-shaped structure. A filter cartridge 21 is provided inside the side housing 2, and a sliding plate 20 is provided inside the side housing 2, with the sliding plate 20 fixed to the filter cartridge 21. A support assembly for supporting the filter cartridge 21 is provided inside the inlet pipe 3, and the sliding plate 20... A mounting hole is provided at the top, and a connecting post 12 is welded into the mounting hole. A push plate 17 is slidably connected to the outside of the connecting post 12. A sealing gasket 14 that fits against the filter cartridge 21 is adhered to the outside of the push plate 17. A second spring 11 is sleeved on the outside of the connecting post 12, and the two ends of the second spring 11 are fixed to the push plate 17 and the slide plate 20, respectively. When needed, water flows in through the inlet pipe 3. At this time, under the action of water pressure, the push plate 17 will be pushed to move along the connecting post 12, thereby allowing water to enter the filter cartridge. Inside the filter cartridge 21, when the push plate 17 moves, it will squeeze the second spring 11. At this time, the second spring 11 will generate elastic force when squeezed. When the water pressure pushes the push plate 17 to the point where the elastic force of the second spring 11 is equal to the force of the water pressure, the elastic force of the second spring 11 and the force of the water pressure will cancel each other out, so that the push plate 17 stops moving. At this time, the push plate 17 seals the space between the push plate 17 and the filter cartridge 21 through the sealing gasket 14, preventing water from entering the top of the push plate 17. This allows the water that has entered the filter cartridge 21 to enter the outlet pipe 6 through the filter holes on the filter cartridge 21 located below the push plate 17 and be discharged. When it is necessary to increase the water flow of the outlet pipe 6, the water pressure is increased, so that the push plate 17 continues to move, changing the position of the push plate 17 to expose more of the filter cartridge 21, thereby increasing the water flow of the outlet pipe 6. This allows the water flow to be adjusted adaptively according to the water pressure, which is convenient for the use of the Y-type filter and improves the applicability of the Y-type filter. The top of the side housing 2 is provided with a locking assembly for fixing the filter cartridge 21.

[0022] In this utility model, the support assembly includes a support ring 13, which is welded inside the water inlet pipe 3 near the side housing 2. A U-shaped groove 18 is formed at the top of the support ring 13, and the filter cartridge 21 is inserted into the U-shaped groove 18. Inserting the filter cartridge 21 into the U-shaped groove 18 on the support ring 13 provides support for the filter cartridge 21, ensuring stable installation. The locking assembly includes a fixing ring 15, which is welded to the top of the side housing 2. A top cover 1 is provided inside the fixing ring 15. A connecting post 12 passes through the top cover 1 and is fixed to it. A connecting block 16 is welded to the top of the connecting post 12. The circumference of the connecting block 16... The outer wall has multiple insertion holes 9. Two symmetrically distributed fixing rods 10 are welded to the top of the fixing ring 15. A telescopic rod is fixed to one side of the fixing rod 10 by bolts. An insertion block 7 is fixed to one end of the telescopic rod by bolts. The insertion block 7 is inserted into the insertion hole 9. After the filter cartridge 21 has been used for a long time, the insertion block 7 is pulled to move it and disengage it from the insertion hole 9. At this time, the top cover 1 can be removed from the fixing ring 15. At the same time, the top cover 1 will drive the sliding plate 20 to move through the connecting column 12. The sliding plate 20 will drive the filter cartridge 21 to move, thereby removing the filter cartridge 21 from the side shell 2, which makes it easier for the staff to disassemble and clean the filter cartridge 21.

[0023] In particular, a first spring 8 is sleeved on the outer side of the telescopic rod, and the two ends of the first spring 8 are fixed to the insert block 7 and the fixing rod 10 respectively. The first spring 8 provides elastic support for the insert block 7, so that the insert block 7 will not move easily. When the insert block 7 moves, it will squeeze the first spring 8. At this time, the insert block 7 can be reset by the force of the first spring 8. A limiting block 19 is welded to one side of the connecting column 12 located inside the side housing 2 to block the push plate 17. The limiting block 19 resets the push plate 17, thereby preventing the push plate 17 from detaching from the connecting column 12 when it is reset by the force of the second spring 11. A flange 5 is welded to one end of the inlet pipe 3 and the outlet pipe 6 on opposite sides. A sealing ring 4 is glued to one side of the flange 5. The sealing ring 4 can seal the outlet pipe 6 and the inlet pipe 3 when the inlet pipe 3 and the outlet pipe 6 are connected through the flange 5.

[0024] Working principle: When needed, water flows in through the inlet pipe 3. Under water pressure, the push plate 17 moves along the connecting column 12, allowing water to enter the filter cartridge 21. As the push plate 17 moves, it compresses the second spring 11. This compression generates elasticity in the second spring 11. When the water pressure pushes the push plate 17 to a point where the elasticity of the second spring 11 equals the water pressure, the elasticity of the second spring 11 cancels out the water pressure, thus stopping the push plate 17 from moving. At this point, the push plate 17 stops moving through the sealing gasket 14. The sealing between plate 17 and filter cartridge 21 prevents water from entering above the push plate 17. Water entering the filter cartridge 21 then enters the outlet pipe 6 through the filter holes located below the push plate 17. When it is necessary to increase the water flow of the outlet pipe 6, the water pressure is increased, causing the push plate 17 to continue moving and changing its position to expose more of the filter cartridge 21. This increases the water flow of the outlet pipe 6, allowing the water flow to be adjusted adaptively according to the water pressure. This facilitates the use of the Y-type filter and improves its applicability.
