[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters of the transported medium. The control of the valve can adopt a variety of transmission methods, and it can act according to predetermined requirements under the action of pressure, temperature or other forms of sensing signals, or simply open or close without relying on sensing signals. The valve relies on a driving or automatic mechanism to make the opening and closing member perform lifting, sliding, swinging or rotating movements, thereby changing the size of its flow passage area to achieve its control function.

[0003] In the existing valves, the valve housing is provided with an end cover for closing the inside of the valve housing, and the end cover is usually fixedly installed on the valve housing by means of screw fastening; when it is necessary to disassemble the end cover to repair and maintain the valve core inside the valve housing, it needs to be disassembled manually, with low production efficiency and inconvenient disassembly; a valve end cover that can be quickly disassembled is provided to alleviate the problems mentioned above.

[0026] Please refer to Figures 1-6, A valve end cover that can be quickly disassembled, including an end cover body 1. Above the end cover body 1, there is a valve housing 2. One end of the valve housing 2 for installing the end cover body 1 is fixedly provided with a convex edge 3. The top of the end cover body 1 is in contact with the lower ground surface of the convex edge 3 of the valve housing 2. A quick-lock assembly 5 is arranged at the middle position inside the end cover body 1. Fixing components 4 are arranged at the four corners of the end cover body 1 and the convex edge 3. The fixing component 4 includes a limit hole 43. A limit hole 43 penetrating the convex edge 3 is opened on the convex edge 3 located on the outer circumference of the valve housing 2. A fixing hole 42 is opened on the upper surface of the end cover body 1 corresponding to the position of the limit hole 43. A fixing cylinder 44 is fixedly installed on the inner wall of the fixing hole 42. The bottom end of the fixing cylinder 44 is flush with the bottom end of the fixing hole 42. The top end of the fixing cylinder 44 penetrates the end cover body 1 and the convex edge 3 and extends to the outside of the device.

[0027] Please refer to Figures 1-6 , The fixing component 4 further includes a guide groove 49. Symmetrically distributed guide grooves 49 are opened on the outer surface of the fixing cylinder 44 located in the limit hole 43. Connecting rods 47 are slidably arranged inside both of the two guide grooves 49. One end of the connecting rod 47 close to the inner wall of the limit hole 43 is fixedly connected with an arc-shaped plate 48. The outer surface of one side of the arc-shaped plate 48 is in contact with the inner wall of the limit hole 43. A square groove 41 is opened on the lower bottom surface of the end cover body 1 corresponding to the position of the fixing hole 42. The inner top surface of the square groove 41 is communicated with the fixing hole 42. An L-shaped plate 46 is vertically arranged inside the fixing hole 42. One side of the top end of the L-shaped plate 46 is fixedly connected with the end of the connecting rod 47 away from the arc-shaped plate 48. The bottom of the L-shaped plate 46 is horizontally arranged inside the square groove 41 and is slidably matched with the square groove 41. Symmetrically distributed electric push rods 45 are fixedly arranged on the inner side wall of the square groove 41. One end of the bottom of both L-shaped plates 46 facing away from each other is fixedly connected with the extending end of the electric push rod 45.

[0028] In this embodiment, when the electric push rod 45 is started, the extending end of the electric push rod 45 pushes the L-shaped plate 46 to move. The L-shaped plate 46 drives the connecting rod 47 to move along the guide groove 49 towards the inside of the fixing cylinder 44. The connecting rod 47 drives the arc-shaped plate 48 to move, so that the arc-shaped plate 48 is disengaged from the inner wall of the limit hole 43, realizing the disassembly of the end cover body 1 and the valve housing 2. Compared with the traditional method of fastening with screws, it is beneficial to improve the convenience of its disassembly and installation and improve the disassembly efficiency.

[0029] Please refer to Figures 1-6, the quick-lock component 5 includes an installation cavity 51. The installation cavity 51 is formed inside the end cover body 1. At the bottom of the inner cavity of the installation cavity 51, a gear ring 52 is rotatably arranged. On the inner ring surface of the gear ring 52, triangular blocks 56 are fixedly installed at equal intervals along its circumference. On the inclined surface of each triangular block 56 facing the center of the circumference, a pressing rod 57 is slidably arranged. At the bottom of the convex edge 3 above the installation cavity 51, L-shaped grooves 59 are evenly arranged along its circumference. A connecting groove 510 is communicated and opened between the installation cavity 51 and each L-shaped groove 59. Inside the L-shaped groove 59, a moving plate 58 is arranged. The bottom end of the moving plate 58 sequentially passes through the L-shaped groove 59 and the connecting groove 510 and is arranged inside the installation cavity 51. The end of the horizontal section of the moving plate 58 inside the installation cavity 51 is fixedly sleeved on the outside of the top end of the pressing rod 57.

[0030] In this embodiment, when the motor 54 is started to operate, the output end of the motor 54 drives the driving gear 55 to rotate. The driving gear 55 drives the gear ring 52 to rotate. When the gear ring 52 drives the triangular block 56 to rotate and contact the bottom end of the pressing rod 57, the triangular block 56 pushes the pressing rod 57 to move towards the center of the installation cavity 51. The pressing rod 57 drives the moving plate 58 to move until the horizontal section at the top of the moving plate 58 disengages from the clamping at the top end of the L-shaped groove 59, releasing the fixed relationship between the end cover body 1 and the convex edge 3, thus improving the reliability of the device in use.

[0031] Please refer to Figures 1-6 , the quick-lock component 5 further includes a rectangular cavity 53. The rectangular cavity 53 is communicated and opened inside the end cover body 1 on one side of the installation cavity 51. At the bottom of the inner cavity of the rectangular cavity 53, a motor 54 is fixedly installed. The output end of the motor 54 is fixedly connected with a driving gear 55. The driving gear 55 meshes with the gear ring 52 for transmission.

[0032] Furthermore, the structure of the installation cavity 51 is "U"-shaped, and the structure of the moving plate 58 is "Z"-shaped. The size of the horizontal section at the top of the moving plate 58 is the same as the size of the top end of the L-shaped groove 59, and the moving plate 58 can slide horizontally inside the L-shaped groove 59. The installation and fixation of the end cover body 1 and the convex edge 3 can be realized conveniently by moving the moving plate 58 inside the L-shaped groove 59 and engaging it with the L-shaped groove 59.

[0033] Working principle: During use, when it is necessary to disassemble the end cover from the valve, first start the motor 54 to drive the rotation of the driving gear 55. The driving gear 55 drives the rotation of the gear ring 52. When the gear ring 52 drives the triangular block 56 to rotate and contact the bottom end of the pressing rod 57, the triangular block 56 pushes the pressing rod 57 to move towards the center of the installation cavity 51. The pressing rod 57 drives the moving plate 58 to move until the horizontal section at the top of the moving plate 58 disengages from the clamping connection at the top end of the L-shaped groove 59, releasing the preliminary fixation of the end cover body 1 and the convex edge 3. Subsequently, start the electric push rod 45 to push the L-shaped plate 46 to move. The L-shaped plate 46 drives the connecting rod 47 to move along the guiding groove 49 towards the inside of the fixed cylinder 44. The connecting rod 47 drives the arc-shaped plate 48 to move, so that the arc-shaped plate 48 does not fit against the inner wall of the limiting hole 43, and finally realizes the disassembly of the end cover body 1 and the valve housing 2, avoiding manual disassembly and being more simple and convenient to operate.
