[0003] The filter tee includes a tee, a filter cartridge, and a bottom cover. The filter cartridge is inserted into the tee, and the bottom cover is connected to the tee by multiple bolts, and the filter cartridge is fixed inside the tee by the bottom cover.

[0004] When cleaning or replacing the filter screen, multiple bolts need to be removed, then the bottom cover needs to be removed, and then the filter cartridge needs to be taken out. The process of removing the bottom cover by removing multiple bolts is cumbersome and inefficient, making it inconvenient to disassemble the filter cartridge. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a three-way device to solve the technical problem that the filter cartridge is inconvenient to disassemble due to the use of bolts for fixing in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a three-way device, including: Tee assembly, including tees; A filter cartridge is slidably inserted into the tee, and one end of the filter cartridge is limited by the tee; A slag discharge assembly is slidably connected to the tee, and its sliding path has an end that abuts against the other end of the filter cartridge to confine the filter cartridge within the tee in a limited position and a disengaged position from the filter cartridge; and A limiting component is inserted into the tee and the slag discharge component, and has a fixed state that restricts the movement of the slag discharge component relative to the tee and an active state that restricts the slag discharge component from moving away from the slag discharge component.

[0007] In one embodiment, the tee assembly further includes a limiting frame, the limiting frame being connected to the tee and forming a slot with one open end between the limiting frame and the tee; The slag discharge assembly is slidably inserted into the slot.

[0009] In one embodiment, the limiting component includes a limiting pin, which is slidably inserted into the first limiting hole and the second limiting hole.

[0010] In one embodiment, the tee has a receiving cavity and an inlet channel, a outlet channel, and a slag outlet channel communicating with the receiving cavity; The filter cartridge is inserted into the receiving cavity through the slag discharge channel, and one end of the filter cartridge abuts against the inner wall of the receiving cavity; the filter cartridge is connected to the liquid inlet channel and the slag discharge channel, and the filter holes of the filter cartridge are connected to the liquid discharge channel.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] To address the technical problem of inconvenient filter cartridge disassembly due to bolt fixing, this utility model provides a three-way device that facilitates filter screen disassembly.

[0022] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a three-way device in one embodiment of the present invention. The three-way device includes a three-way component 1, a filter cylinder 2, a slag discharge component 3, and a limiting component 4. The three-way component 1 includes a three-way 11; the filter cylinder 2 is slidably inserted into the three-way 11, and one end of the filter cylinder 2 is limited by the three-way 11; the slag discharge component 3 is slidably connected to the three-way 11, and the sliding path has a state of abutting against the other end of the filter cylinder 2 to limit the filter cylinder 2 within the three-way 11 and a state of disengagement from the filter cylinder 2; the limiting component 4 is inserted into the three-way 11 and the slag discharge component 3, and has a state of limiting the movement of the slag discharge component 3 relative to the three-way 11 and a state of movement of the slag discharge component 3.

[0023] When it is necessary to disassemble the filter cartridge 2, slide the limiting component 4 so that the limiting component 4 is in an active state. At this time, the slag discharge component 3 can move relative to the tee 11. Slide the slag discharge component 3 so that the slag discharge component 3 is disengaged from the tee 11. At this time, the restriction on the filter cartridge 2 is released, and the filter cartridge 2 can slide out of the tee 11 for cleaning and maintenance.

[0024] The three-way device of this invention replaces the traditional bolt connection with a slidingly inserted filter cartridge 2, a sliding slag discharge assembly 3, and a pluggable limiting assembly 4. When cleaning or replacement is required, simply pull out the limiting assembly 4 to slide open the slag discharge assembly 3 and directly remove the filter cartridge 2 without disassembling multiple bolts.

[0025] It should be understood that the slag discharge assembly 3 and the tee 11 can be slidably connected via a slider or groove, or via a sliding rod or sleeve. Specifically, for example... Figure 1 and Figure 4 As shown, in one embodiment, the tee assembly 1 further includes a limiting frame 12, which is connected to the tee 11 and forms a slot 1a with one end open between the limiting frame 12 and the tee 11; the slag discharge assembly 3 is slidably inserted into the slot 1a.

[0026] The limiting frame 12 and the body of the tee 11 together form a slot 1a with one end open. The slag discharge component 3 can slide smoothly along the slot 1a to achieve precise alignment and reliable guidance.

[0027] It should be understood that the limiting component 4 can be slidably inserted into the slot 1a on the tee 11 and the slag discharge component 3, or other methods can be used to achieve the sliding connection between the limiting component 4 and the tee 11 and the slag discharge component 3, specifically, such as Figure 4 As shown, in one embodiment, the tee 11 has a first limiting hole 11a; the slag discharge assembly 3 has a second limiting hole 3a relative to the first limiting hole 11a, and the limiting assembly 4 is inserted into the first limiting hole 11a and the second limiting hole 3a.

[0028] By correspondingly opening the first limiting hole 11a and the second limiting hole 3a on the tee 11 and the slag discharge assembly 3, the position of the slag discharge assembly 3 can be fixed by inserting the limiting pin 41. This provides a simple and reliable locking method, and the limiting assembly 4 is easy to insert and remove, completely solving the problem of difficult bolt removal.

[0029] It should be understood that the limiting component 4 can be a limiting block, a limiting rod, etc., specifically, such as Figure 4 As shown, in one embodiment, the limiting component 4 includes a limiting pin 41, which is slidably inserted into the first limiting hole 11a and the second limiting hole 3a. In this embodiment, the limiting pin 41 can be a cylinder or a stepped column.

[0030] The limiting pin 41, as a key component for sliding insertion and removal, passes through the aligned first limiting hole 11a and second limiting hole 3a to limit the sliding of the slag discharge assembly 3. It has a simple structure, low cost, and is suitable for frequent disassembly and assembly.

[0031] like Figure 2 , 4 As shown in Figure 9, in one embodiment, the limiting pin 41 is stepped columnar, with its small-diameter section passing through the first limiting hole 11a and the second limiting hole 3a. The small-diameter section of the limiting pin 41 has an annular groove 41a. The limiting component 4 also includes an elastic retaining ring 42, which faces multiple cards 42a protruding into the annular groove 41a. The multiple cards 42a are distributed circumferentially at intervals along the elastic retaining ring 42. The cards 42a are embedded in the annular groove 41a.

[0032] The engagement of the card 42a in the elastic retaining ring 42 with the limiting pin 41 restricts the sliding of the limiting pin 41 relative to the first limiting hole 11a and the second limiting hole 3a. When it is necessary to release the restriction on the limiting pin 41, the card 42a is driven to deform, causing the card 42a to disengage from the annular groove 41a. The card 42a is arc-shaped and can elastically deform in the direction of disengaging from the annular groove 41a under the influence of external force.

[0033] It should be understood that an elastic wire can also be used to pass through the limiting pin 41 to limit the sliding of the limiting pin 41.

[0034] like Figure 5 and 8 As shown, in one embodiment, the tee 11 has a receiving cavity 11e and an inlet channel 11b, a outlet channel 11c, and a slag discharge channel 11d connected to the receiving cavity 11e; the filter cartridge 2 is inserted into the receiving cavity 11e through the slag discharge channel 11d, and one end of the filter cartridge 2 abuts against the inner wall of the receiving cavity 11e; the filter cartridge 2 is connected to the inlet channel 11b and the slag discharge channel 11d, and the filter holes of the filter cartridge 2 are connected to the outlet channel 11c.

[0035] After the fluid enters the inlet channel 11b, it enters the filter cartridge 2 through the inlet channel 11b. The liquid in the fluid passes through the filter holes of the filter cartridge 2, and the impurities in the fluid are intercepted inside the filter cartridge 2. The filter cartridge 2 is inserted into the receiving cavity 11e from the slag discharge channel 11d. One end abuts against the inner wall to achieve a limiting position, and the other end of the filter cartridge 2 is abutted and limited by the slag discharge assembly 3, so that the filter cartridge 2 can be fixed in the receiving cavity 11e.

[0036] To facilitate the discharge of impurities trapped in filter cartridge 2, such as Figure 1 and Figure 3 As shown, in one embodiment, the slag discharge assembly 3 includes a cover plate 31 and a slag discharge pipe 32. The cover plate 31 slides in the slot 1a, and the slag discharge pipe 32 is connected to the cover plate 31 and communicates with the slag discharge channel 11d.

[0037] In this embodiment, the slag discharge pipe 32 is opened, and the slag discharge pipe 32 is connected to the slag discharge channel 11d via the cover plate 31, so that the impurities in the filter cartridge 2 can be discharged through the slag discharge pipe 32.

[0038] In order to control the opening and closing of the slag discharge pipe 32, therefore, as follows: Figure 3 , 4 As shown in Figure 6, in one embodiment, the slag discharge assembly 3 further includes a valve 33, which is disposed on the slag discharge pipe 32 and is used to control the opening and closing of the slag discharge pipe 32.

[0039] In this embodiment, when it is necessary to discharge the impurities intercepted by the filter cartridge 2, the valve 33 is opened, and the impurities in the filter cartridge 2 can be discharged through the slag discharge pipe 32. After the slag discharge is completed, the valve 33 is closed to avoid affecting the filtration of the filter cartridge 2.

[0040] To prevent leakage at the junction of tee 11 and cover plate 31, therefore, as follows: Figure 6 and Figure 7 As shown, in one embodiment, the slag discharge assembly 3 further includes a sealing ring 34, which is disposed between the tee 11 and the cover plate 31 to seal the gap between the tee 11 and the cover plate 31.

[0041] In this embodiment, by setting a sealing ring 34, the sealing ring 34 can seal the gap between the tee 11 and the cover plate 31, thus preventing water leakage at the tee 11 and the cover plate 31.

[0042] In order to apply an elastic abutment force to the sliding cover plate 31, so that the cover plate 31 is tightly against the sealing ring 34, for this purpose, as follows: Figure 7 As shown, in one embodiment, an annular cavity is formed between the peripheral wall of the filter cartridge 2 and the inner wall of the slag discharge channel 11d. The cross-section of the annular cavity is triangular, and the cross-sectional size gradually decreases along the direction away from the cover plate 31. The sealing ring 34 is fitted into the annular cavity and its shape matches the shape of the annular cavity.

[0043] In this embodiment, the sealing ring 34 is embedded in the annular cavity. When the cover plate 31 is inserted into the slot 1a, the cover plate 31 adheres to and squeezes the sealing ring 34, so that the sealing ring 34 adheres to the inner wall of the annular cavity. The squeezing force of the sealing ring 34 after being compressed can restrict the sliding of the cover plate 31 relative to the slot 1a, and the elastic force can seal the cover plate 31 with the filter cartridge 2 and the tee 11.

[0044] To facilitate the insertion of the cover plate 31 into the slot 1a, for this purpose, such as Figure 7 As shown, in one embodiment, the end of the cover plate 31 that is first inserted into the slot 1a is provided with a guide slope 31a, which is located on the side of the cover plate 31 near the tee 11.

[0045] In this embodiment, when the cover plate 31 is inserted into the slot 1a, the guide slope 31a only partially contacts the sealing ring 34, which can guide the cover plate 31 into the slot 1a, making it easier for the cover plate 31 to be inserted.

[0046] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
