In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0022] Please see Figure 1 and Figure 5This utility model provides a valve cover that is easy to disassemble, including a cover body 1 and a washer 2. The washer 2 is disposed on the top of the cover body 1 and connected to the cover body 1. The cover body 1 and the washer 2 are brought into contact by applying force. A force-applying part is provided between the cover body 1 and the washer 2. The force-applying part is used for inserting a force-applying tool. When the force-applying tool is inserted into the force-applying part, the force-applying tool separates the washer 2 from the cover body 1.

[0023] In some embodiments, such as Figures 1 to 4 As shown, the force-applying part includes a first groove 3 provided on the washer 2. The first groove 3 is provided at one end of the washer 2 near the cover 1, so that there is a certain gap between the bottom part of the washer 2 and the cover 1, so that when the washer 2 is separated from the cover 1, the force-applying tool can enter the first groove 3 relatively easily.

[0024] The first groove 3 extends radially outward along the washer 2. In some embodiments, one end of the first groove 3 communicates with the inner wall of the washer 2, while the end of the first groove 3 away from the inner wall of the washer 2 does not extend to the outer wall of the washer 2. In some embodiments, one end of the first groove 3 communicates with the outer wall of the washer 2, while the end of the first groove 3 away from the outer wall of the washer 2 does not communicate with the outer wall of the washer 2, meaning the force-applying tool is inserted from the outer wall of the cover. Since neither end of the first groove 3 penetrates the inner or outer wall of the first groove 3, the connection between the bottom of the washer 2 and the cover 1 is continuous without interruption, thus minimizing the impact on the connection between the washer 2 and the cover 1.

[0025] In some preferred embodiments, a first groove 3 is provided at the inner edge of the washer 2, and the first groove 3 is arranged obliquely along the radial direction of the washer 2, such as... Figure 4 As shown. Specifically, the first groove 3 is inclined downwards from the side away from the cover 1 towards the side closer to the cover 1, thus forming a beveled structure with a certain angle inside the washer 2. That is, the first groove 3 is inclined downwards from the inside out. When the force-applying tool is inserted into the first groove 3, its working end can naturally slide along the inclined direction of the first groove 3. This design not only facilitates the positioning and guidance of the force-applying tool, but also ensures that the force transmission is more stable and controllable during the application of force. In addition, the design of this beveled structure also optimizes the contact method between the force-applying tool and the washer 2, reducing the frictional loss that may occur during operation.

[0026] Furthermore, multiple first grooves 3 can be provided at intervals along the circumference of the inner edge of the washer 2, so that force can be applied to the washer 2 at multiple points, thereby making it easier to separate the washer 2 from the cover 1.

[0027] In some embodiments, a first groove 3 is provided, and two first grooves 3 are symmetrically arranged along the axis of the washer 2. The two first grooves 3 are located on opposite sides of the inner side of the washer 2 and are completely symmetrical with respect to the central axis of the washer 2. This symmetrical layout not only ensures balanced force on the force-applying tool during operation, but also effectively avoids the washer 2 from tilting or deforming due to force on one side. When the force-applying tool acts on both first grooves 3 simultaneously, the symmetrical structure enables the applied force to be evenly transmitted to all parts of the washer 2, thereby improving the stability and reliability of the assembly or disassembly process. In addition, this symmetrical design also facilitates operation from different angles, improving the convenience and adaptability of operation.

[0028] In some embodiments, such as Figures 5 to 7 As shown, the force-applying part includes a second groove 4 disposed on the cover 1. The second groove 4 is located at the end of the cover 1 near the washer, and after the washer 2 is fitted with the cover 1, the projection of the washer 2 and the second groove 4 in the axial direction of the cover 1 intersects. The second groove 4 in the axial projection of the cover 1 forms a certain degree of overlap with the inner edge of the washer 2. That is, after the washer 2 and the cover 1 are installed, part of the second groove 4 is located at the bottom of the washer 2, and the rest is not blocked by the washer 2. The washer 2 is partially located at the top of the second groove 4, and the part along the radial direction of the washer is connected to the cover 1. This structural design allows the force-applying tool to simultaneously apply force to the washer 2 when acting on the second groove 4, thereby achieving synchronous operation of the cover 1 and the washer 2. This arrangement not only optimizes the force transmission path but also enhances the overall integrity of the assembly structure, ensuring that the force transmission is more direct and effective during disassembly.

[0029] The second groove 4 includes a first surface 5 and a second surface 6. The first surface 5 is located on the side of the second groove 4 near the center of the cover 1, and the second surface 6 is located on the side of the second groove 4 near the outer wall of the cover 1. The first surface 5 is an arc surface. This streamlined structure not only facilitates the smooth insertion of the force-applying tool, but also effectively disperses the contact stress during operation.

[0030] In some embodiments, the second surface 6 is also an arc surface, and the smooth transition between the first surface 5 and the second surface 6 forms an arc-shaped groove in the first groove 3. The second surface 6 is not connected to the outer wall of the cover 1. During actual disassembly, this double-arc structure design allows the force application tool to select the optimal point of application according to operational needs, ensuring operational stability and improving disassembly efficiency. There are at least two second grooves 4, and the two second grooves 4 are symmetrically arranged along the axis of the cover 1.

[0031] The outer diameter of washer 2 is the same as that of cover 1. The inner wall of washer 2 is closer to the outer wall of cover 1 than the junction of the first surface 5 and the second surface 6. The curvature of the first surface 5 and the second surface 6 is the same. After washer 2 is installed on cover 1, the inner wall of washer 2 does not exceed the lowest point of the second groove 4. The space for the force-applying tool to be inserted is large enough, while avoiding excessive cutting that would affect the structural strength. The symmetrical curved surface design forms a natural guide channel, allowing the force-applying tool to automatically center and position itself.

[0032] In some embodiments, a second groove 4 is provided inside the cover 1, and a first groove 3 is provided at the corresponding position of the washer 2. The cooperation between the first groove 3 and the second groove 4 facilitates the operation of the force-applying tool. The first groove 3 and the second groove 4 form complementary guide tracks, providing clear operating path guidance for the force-applying tool and ensuring that the tool is always kept at the optimal force-applying angle.

[0033] The second groove 4 is 5mm-10mm long, 1mm-4mm wide, and 3mm-5mm deep. When disassembly is required, the operator simply inserts a special tool or flathead screwdriver into the groove and gently pries it using leverage to quickly and effortlessly separate the washer 2 from the cover 1. This design not only avoids component damage that may occur with traditional disassembly methods but also greatly improves maintenance efficiency, making it particularly suitable for valve systems requiring frequent maintenance.

[0034] Disassembly process: Insert a flathead screwdriver into the force application part and slowly tap to remove the sealing gasket 2, causing a gap and loosening at the contact surface between the gasket 2 and the cover 1. The force application part is designed so that the overall shape and sealing performance of the gasket 2 will not be damaged when removing the gasket 2, reducing the risk of damage to the gasket 2 and the cover 1 during disassembly, improving the convenience of disassembly, and allowing the gasket 2 and the cover 1 to be reused multiple times, reducing costs.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
