[0003] For example, the authorization announcement number is "CN214331532U" which is a conveniently detachable dust-proof disc valve. The outer peripheral surface of the cylinder is sealed with a telescopic sleeve, and the telescopic sleeve is sealed and connected to the push rod away from the cylinder. The cylinder is provided with a fixing mechanism for fixing the telescopic sleeve. When the piston rod of the cylinder moves, the piston rod of the cylinder pushes the push rod away from the cylinder, and the push rod drives one end of the telescopic sleeve away from the cylinder. The telescopic sleeve extends and wraps around the piston rod of the cylinder. The telescopic sleeve prevents dust from adhering to the outer peripheral surface of the piston rod of the cylinder, thereby reducing the possibility of fine gaps between the cylinder and the piston rod of the cylinder. However, in the use of the dust-proof disc valve, the control cylinder is supported and installed at a single point, and the overall specifications of the dust-proof disc valve are relatively large. In addition, the cylinder and the dust-proof disc valve are not integrated, and a certain amount of shaking will occur during operation. The single-point support cylinder is relatively large, and the dust-proof disc valve is prone to breakage when used for a long time, which reduces the use strength of the dust-proof disc valve and shortens the service life of the dust-proof disc valve.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] See also Figure 1-6 : In this embodiment, a conveniently detachable dustproof disc valve includes a straight cylinder 4, and a dustproof disc valve 1 is fixedly connected to the rear end face of the straight cylinder 4. How to operate and use the dustproof disc valve 1 is already existing technology, and no further elaboration is given. The model is selected according to usage requirements. A fixed structure 2 is connected to the top right side of the dustproof disc valve 1, and a cylinder 5 is connected to the top of the fixed structure 2. The model of the cylinder 5 is selected according to usage requirements. A curved block 6 is fixedly connected to the output end of the cylinder 5, and a screw 7 is inserted into the inner wall of the curved block 6. The outer wall of the screw 7 is threadedly connected to a bracket 9. The screw 7 is subjected to force to rotate back and forth through the upper part of the outer wall of the bracket 9. The lower part of the outer wall of the bracket 9 is fixedly connected to the front valve stem of the dustproof disc valve 1, and the inner wall of the straight cylinder 4 is connected to the supporting structure 3.

[0023] The fixed structure 2 includes a square frame 201 and a straight plate 202. The bottom of the square frame 201 is fixedly connected to the top right side of the dustproof disc valve 1, the inner wall of the square frame 201 is fixedly connected to the outer wall of the straight plate 202, and a round rod 203 is slidably connected to the front of the square frame 201. The round rod 203 slides back and forth through the circular opening on the front of the square frame 201 under force, and a round plate 204 is fixedly connected to the front of the round rod 203.

[0024] The outer wall of the round rod 203 is sleeved with a spring 205, and the two ends of the spring 205 are respectively fixed to the front of the square frame 201 and the rear end of the round plate 204. After the round plate 204 is forced to move forward, it rebounds by the elastic force of the spring 205. The front of the round plate 204 is fixed with a bent rod 206, which is convenient for moving the round plate 204 forward. The top of the straight plate 202 is fixed to the bottom of the cylinder 5, and the rear of the outer wall of the round rod 203 is plugged into the front round mouth of the straight plate 202.

[0025] By moving the bent rod 206 forward in the fixed structure 2, the moving bent rod 206 moves the circular plate 204, and the circular plate 204 moves the round rod 203 forward, and the outer wall of the round rod 203 is separated from the straight plate 202 at the rear. At the same time, the circular plate 204 stretches the spring 205, and then lifts the cylinder 5 upward to separate the straight plate 202 from the inside of the square frame 201, completing the disassembly of the cylinder. While facilitating disassembly, the original single-point support form is changed, which improves the installation stability of the dustproof disc valve and the cylinder, improves the use strength of the dustproof disc valve, and ensures the service life of the dustproof disc valve.

[0026] The supporting structure 3 includes a support leg 301 and a vertical tube 302. The rear of the outer wall of the support leg 301 is plugged into the inner wall of the straight tube 4. The outer wall of the support leg 301 is threadedly connected to the inner wall of the vertical tube 302. The vertical tube 302 is subjected to force and rotates up and down through the threads on the outer wall of the support leg 301. The bottom of the vertical tube 302 is fixedly connected to a bottom plate 303. The front of the screw rod 7 is fixedly connected to a handle 8, which facilitates the screw rod 7 to rotate back and forth.

[0027] Working principle:

[0028] The dustproof disc valve drives the valve plate to move through the valve stem rotating shaft, thereby realizing the valve switching action. This rotational movement makes the valve opening and closing process fast and reliable. The sealing design, the valve plate inside the dustproof disc valve is usually made of wear-resistant materials such as carbide and ceramics. These materials have good mechanical properties and wear resistance, can effectively resist material erosion, and extend the service life of the sealing surface, thereby avoiding the formation of gaps inside the dustproof disc valve to prevent dust from passing through, thereby realizing the dustproof of the dustproof disc valve.

[0029] Dustproof disc valve installation:

[0030] The front and rear flanges of the dustproof disc valve 1 are connected to the external pipes through the matching bolts, and then the rear of the outer wall of the support leg 301 is plugged into the inner wall of the straight cylinder 4. Then the vertical cylinder 302 is rotated downward through the thread below the outer wall of the support leg 301. The rotating vertical cylinder 302 moves the bottom plate 303 downward until the bottom of the bottom plate 303 is pressed against the ground, completing the support of the dustproof disc valve and improving the installation stability.

[0031] Disassembly and assembly of dustproof disc valve cylinder:

[0032] The handle 8 is made to rotate forward with the screw rod 7 through the bracket 9, so that the rear of the outer wall of the screw rod 7 is separated from the curved block 6, and the bent rod 206 is moved forward. The moved bent rod 206 moves the circular plate 204 forward, and the circular plate 204 makes the round rod 203 move forward, and the rear of the outer wall of the round rod 203 is separated from the straight plate 202. At the same time, the circular plate 204 stretches the spring 205, and then the cylinder 5 is lifted upward to separate the straight plate 202 from the inside of the square frame 201, and the cylinder is disassembled, which is convenient for disassembly. At the same time, the original single-point support form is changed, which improves the installation stability of the dust-proof disc valve and the cylinder, and the straight plate 202 is inserted back into the square frame 201. The bent rod 206 is loosened, and the spring 205 provides a rebound force to make the circular plate 204 move the round rod 203 backward, so that the rear of the outer wall of the round rod 203 is plugged into the front round mouth of the straight plate 202.

[0033] Embodiment 2:

[0034] See also Figure 1-6 In this embodiment, a conveniently disassembled dustproof disc valve further includes a sleeve 10, the inner wall of the sleeve 10 is fixedly connected to the outer wall of the bent rod 206.

[0035] Working principle:

[0036] When pulling the curved rod 206 , the hand can hold the outer wall of the sheath 10 , and the sheath 10 protects the hand through its rubber material.
