[0028] Reference Figure 1 、 Figure 2 and Figure 3 A valve body according to an embodiment of the present invention comprises: an adjusting rod 4 and a filter body 1, a connecting pipe 3 and a solenoid valve 2 connected in sequence;

[0029] The connecting pipeline 3 includes a liquid inlet section 31 , a connecting section 32 and a liquid outlet section 33 arranged in sequence. The filter body 1 is connected to the liquid inlet section 31 , the solenoid valve 2 is connected to the liquid outlet section 33 , and the regulating rod 4 has a sealing end 41 .

[0030] The valve body has a first state and a second state. In the first state, the liquid inlet section 31, the connecting section 32, and the liquid outlet section 33 are sequentially connected to form a connecting channel 30. In the second state, the adjusting rod 4 is radially extended through the connecting section 32 of the connecting pipeline 3, and the sealing end 41 is tightly connected to the inner circumferential wall of the connecting section 32 to block the connecting channel 30. The valve body switches between the first and second states by adjusting the position of the adjusting rod 4, thereby opening or blocking the connecting channel 30 according to user needs.

[0031] refer to Figure 4 In some embodiments of the present application, a mounting portion 34 is protruded from the outer wall of the connecting section 32, and the mounting portion 34 is provided with a mounting opening 341 and a mounting channel 342. The mounting opening 341 is located on the side of the mounting portion 34 away from the connecting section 32, and the mounting channel 342 connects the mounting opening 341 with the connecting channel 30. The adjusting rod 4 is sequentially passed through the mounting opening 341 and the mounting channel 342 and is provided with an operating portion 42 at the end of the adjusting rod 4 close to the mounting opening 341.

[0032] The mounting portion 34 provides a stable connection point for the adjusting rod 4 and optimizes the operation method of the adjusting rod 4. The design of the mounting opening 341 enables the adjusting rod 4 to be more conveniently inserted or removed, thereby improving the convenience of use.

[0033] Some embodiments of the present application further include a sealing sleeve 5, which is fitted over the end of the adjusting rod 4 facing the connecting section 32 to form the sealed end 41. The sealing sleeve 5 provides a good sealing effect and can be designed and adjusted according to the internal dimensions of the connecting passage 30 to seal the connecting passage 30. The sealing sleeve 5 also reduces external wear and corrosion on the adjusting rod 4, thereby extending the service life of the adjusting rod 4. In a specific embodiment of the present application, the end of the adjusting rod 4 facing the connecting section 32 is provided with a mounting groove for mounting the sealing sleeve 5.

[0034] In some embodiments of the present application, a threaded portion 43 is provided on the outer peripheral wall of the adjusting rod 4. The threaded portion 43 is located between the sealing end 41 and the operating end. The peripheral wall of the mounting channel 342 is provided with threads. The adjusting rod 4 is threadedly connected to the mounting channel 342 via the threaded portion 43, allowing the adjusting rod 4 to be precisely adjusted and fixed within the mounting channel 342, thereby achieving a better sealing effect and operational stability. The threaded connection also makes it easier for users to remove and replace the adjusting rod 4, thereby reducing maintenance costs. Correspondingly, the operating portion 42 can be a slotted groove or a cross groove corresponding to a screwdriver. Using a screwdriver to rotate the adjusting rod 4 can achieve the switching of the valve body between the first state and the second state.

[0035] refer to Figure 5 In some embodiments of the present application, a gland 6 is further included. The gland 6 covers the mounting opening 341 and defines an operating through-hole 61. The operating portion 42 extends through the operating through-hole 61. When the valve body is in the first state, the operating portion 42 protrudes from or is flush with the end surface of the operating through-hole 61. The gland 6 effectively prevents foreign matter such as dust and moisture from entering the mounting opening 341 and provides additional protection for the adjusting rod 4, thereby improving the durability and reliability of the valve body.

[0036] In some embodiments of the present application, the threaded portion 43 is protruded from the outer peripheral wall of the adjusting rod 4, and a limiting portion 62 is protruded from one end of the pressure cap 6 facing the mounting portion 34. The limiting portion 62 is inserted into the mounting channel 342 and engages with the threaded portion 43 in a limiting manner. Specifically, when the valve body is in the first state, the limiting portion 62 abuts against the threaded portion 43. The limiting portion 62 effectively limits the range of movement of the adjusting rod 4, facilitates a more intuitive perception of the adjustment position by the user during adjustment, ensures the fluid cross-sectional area of ​​the connecting channel in the first state, and prevents the adjusting rod 4 from accidentally loosening or falling off.

[0037] In some embodiments of the present application, a first sealing ring 7 is further included. The first sealing ring 7 is sleeved on the end of the gland 6 facing the mounting portion 34. The gland 6 is sealed to the mounting channel 342 via the first sealing ring 7. Specifically, the first sealing ring 7 can be sleeved on the limiting portion 62. The first sealing ring 7 is provided to further improve the connection stability between the gland 6 and the adjusting rod 4 and prevent liquid leakage.

[0038] Some embodiments of the present application further include a second sealing ring 8 , which is sleeved onto the end of the adjusting rod 4 that faces the mounting opening 341 . The adjusting rod 4 is sealed to the gland 6 via the second sealing ring 8 , thereby improving the sealing performance of the system, extending the service life of the valve body, and simplifying maintenance and replacement. In a specific embodiment, two second sealing rings 8 are provided, spaced apart along the extension direction of the adjusting rod 4 .

[0039] In some embodiments of the present application, a limiting groove 321 is provided on the inner peripheral wall of the connecting section 32 facing the mounting portion 34. When the valve body is in the second state, the end of the sealing end 41 is inserted into the limiting groove 321 to ensure close contact between the sealing end 41 and the inner peripheral wall of the connecting section 32, thereby enhancing the sealing performance of the adjusting rod 4 on the connecting channel 30, reducing the risk of leakage in the second state, and enhancing the stability of the adjusting rod 4 of the valve body in the second state.

[0040] In some embodiments of the present application, the connecting channel 30 extends in the up and down directions, so that the connecting pipeline 3 can utilize space more effectively and reduce the horizontal space occupied. At the same time, the liquid inlet section 31, the connecting section 32, and the connecting section 32 are arranged in sequence from top to bottom, so that the liquid can better utilize the gravitational potential energy under the action of the up and down flow, thereby improving the transmission efficiency.

[0041] In summary, the embodiment of the present invention provides a valve body, which can realize the switching of the valve body between the first state and the second state through the different positions of the adjusting rod 4; when the user needs, such as when cleaning or replacing the filter body 1, the valve body can be switched from the first state to the second state. At this time, the adjusting rod 4 blocks the connecting channel 30, thereby effectively preventing sewage or fine particles from entering the interior of the solenoid valve 2 during the cleaning process, avoiding failure of the solenoid valve 2, and thus significantly improving the safety and stability of the valve body.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
