The electric actuator 12 and the valve body 1 are common devices purchased on the market and known to those skilled in the art. Here, we only use them and do not improve their structure and function. We will not go into details here.

[0035] Working principle:

[0036] When the filter plate 6 needs to be replaced, the new filter plate 6 is first inserted into the through groove 4. The filter plate 6 slides into the guide slope 9 at the top of the sealing ring 5, pushing the sealing ring 5 into the annular groove 7, causing the multiple springs 8 to contract. As the sealing ring 5 is fully inserted into the annular groove 7, the new filter plate 6 is pressed down, pushing the old filter plate 6 out through the through groove 4 at the bottom. When the new filter plate 6 is fully pressed into the inside of the sealing ring 5, the springs 8 return to their original position, moving the sealing ring 5 away from the annular groove 7, allowing the sealing ring 5 to re-engage with the sealing groove 10, thereby sealing the inside of the through groove 4. This design, through the elastic action of the springs 8, the sliding engagement of the sealing ring 5, and the guidance of the guide slope 9, enables the rapid replacement of the filter plate 6, while ensuring the continuity of sealing performance during the replacement process, avoiding fluid leakage, and improving maintenance efficiency. The entire process is simple to operate, requiring no disassembly of the valve body, significantly reducing maintenance costs and time.

[0037] Example 2: Figures 5-6 As shown, the difference between this embodiment and Embodiment 1 is that: a first hydraulic rod 15 is fixedly installed on one side of the connecting pipe 2 corresponding to the through groove 4; a pressing plate is fixedly installed on the telescopic end of the first hydraulic rod 15; a second hydraulic rod 16 is fixedly installed on the bottom end of the connecting pipe 2; a connecting groove 17 is opened at the bottom end of the connecting pipe 2; a connecting slider 18 is slidably installed inside the connecting groove 17; the top end of the connecting slider 18 is fixedly connected to the bottom end of the sealing ring 5; the bottom end of the connecting slider 18 is fixedly connected to the telescopic end of the second hydraulic rod 16 through the linkage frame 19; the first hydraulic rod 15 and the second hydraulic rod 16 are connected through the connecting pipe. A first return spring 20 is sleeved on the outside of the first hydraulic rod 15; one end of the first return spring 20 is fixedly connected to the pressing plate; the other end of the first return spring 20 is fixedly connected to the top end of the connecting pipe 2; a second return spring 21 is fixedly connected to the side wall of the connecting slider 18; the other end of the second return spring 21 is fixedly connected to the inner wall of the connecting groove 17. By setting up connecting slider 18, first hydraulic rod 15, second hydraulic rod 16, first return spring 20 and second return spring 21, the auxiliary sealing ring 5 can move, making it easier to replace filter plate 6.

[0038] Working principle:

[0039] When the filter plate 6 needs to be replaced, first, the new filter plate 6 is inserted into the through slot 4, and the filter plate 6 is in sliding fit with the guide slope 9 at the top end of the sealing ring 5, while pressing the filter plate 6, the palm pushes the pressing plate at the telescopic end of the first hydraulic rod 15 to move downward, thereby pushing the telescopic end of the first hydraulic rod 15 to retract, driving the first return spring 20 to retract, and the telescopic end of the first hydraulic rod 15 retracts to guide the liquid to enter the inside of the second hydraulic rod 16 through the connecting pipe, thereby driving the telescopic end of the second hydraulic rod 16 to extend, and the telescopic end of the second hydraulic rod 16 extends to drive the second return spring 21 to extend, and the connecting sliding block 18 is driven to move towards the second hydraulic rod 16 through the linkage frame 19, thereby driving the sealing ring 5 to slide into the annular groove 7, and the plurality of springs 8 are retracted.

[0040] When the sealing ring 5 completely enters the annular groove 7, the new filter plate 6 is continuously pressed downward, and the old filter plate 6 is pushed out through the through slot 4 at the bottom. When the new filter plate 6 is completely pressed into the inside of the sealing ring 5, the spring 8 returns to the original state, drives the sealing ring 5 to move away from the annular groove 7, and makes the sealing ring 5 and the sealing groove 10 reinserted and fit, thereby sealing the inside of the through slot 4. At the same time, the first return spring 20 and the second return spring 21 return to the original state to drive the telescopic ends of the first hydraulic rod 15 and the second hydraulic rod 16 to return to the original position, drive the sealing ring 5 to move away from the annular groove 7, and facilitate the next replacement. This design realizes the rapid replacement of the filter plate 6 through the elastic effect of the spring 8, the sliding fit of the sealing ring 5 and the guidance of the guide slope 9, ensures the continuity of the sealing performance during the replacement process, avoids the leakage of the fluid, and improves the maintenance efficiency. The whole process is simple to operate, does not need to disassemble the valve body, significantly reduces the maintenance cost and time.

[0041] The above describes the embodiments of the utility model in detail in combination with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the technical field without departing from the purpose of the utility model.
