Description

Technical Field

[0001] This utility model relates to the field of ball valves, and more specifically, to a detachable handle drive assembly for a ball valve. Background Technology

[0002] Ball valves are common and important fluid control devices, widely used in numerous industrial and civil fields. They use a ball as the opening and closing element, with a circular through-hole or channel on the ball. Rotating the ball 90 degrees opens and closes the valve. They feature a compact structure, good sealing performance, low fluid resistance, convenient operation, and rapid opening and closing. In practical applications, they can precisely control the flow rate and direction of fluids, playing a crucial role in scenarios such as petrochemicals, natural gas transportation, and water supply and drainage systems, ensuring the stable operation and safe management of fluid transportation systems.

[0003] The handle drive assembly, as an important component of the ball valve, is used to drive the opening and closing of the ball valve. Existing ball valve handle drive assemblies usually adopt a fixed structure, that is, the handle drive assembly is fixedly connected to the drive shaft on the ball valve. It cannot be disassembled and stored when not in use, resulting in the ball valve occupying a large space, which is inconvenient for storage and transportation. In addition, the fixed handle drive assembly is easily subjected to collisions and damage during transportation, which affects the service life of the ball valve.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a detachable handle drive assembly for a ball valve. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a detachable handle drive assembly for a ball valve.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detachable handle drive assembly for a ball valve, comprising a rod and a rotating wheel located at the top of the rod, wherein the bottom end of the rod is connected to the ball valve drive shaft via a quick-release structure;

[0007] The quick-release structure includes a connecting block fixed to the bottom of the rod and a connecting slot fixed to the top of the ball valve drive shaft. The connecting slot has circular through slots A on both sides. An elastic component that pushes two circular blocks to move to both sides is installed inside the connecting block.

[0008] Preferably, the connecting block is hollow inside, and its base plate is detachably connected to the connecting block by screws. Connecting plates are slidably connected to both sides of the inside of the connecting block. The elastic component is installed between the two connecting plates. The circular block is fixed to the surface of the connecting plate. Circular through grooves B are provided on both sides of the connecting block for the circular block to pass through the inside of the connecting block.

[0009] Preferably, each of the connecting plates is provided with a convex groove, and the elastic component includes two mounting blocks that can be inserted into the convex groove, and a spring is installed between the mounting blocks.

[0010] Preferably, the upper and lower sides of the connecting block are fixedly connected to guide rails A for sliding of slider A, and the connecting plate is fixed between the upper and lower sliders A.

[0011] Preferably, the length of the rod is adjustable, the rod is made of lightweight, high-strength aluminum alloy, and the wheel is made of high-strength engineering plastic.

[0012] Preferably, the rod includes an outer rod connected to the connecting block and an inner rod connected to the rotating wheel. The inner rod is slidably connected to the inside of the outer rod. Multiple screw holes are arranged in a vertical array around the outer side wall of the inner rod, and a through hole is provided at the upper part of the outer side wall of the outer rod.

[0013] Preferably, a disc is fixedly connected to the bottom end of the outer rod below the through hole, and guide rails B for sliding slider B are fixedly connected to the top circumference of the disc. A bearing is fixedly connected to the top end of slider B, and a screw is fixedly connected to the inner ring of the bearing. A rotating plate is fixedly connected to the head of the screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model enables quick assembly and disassembly of the handle drive assembly. Through the design of the quick-release structure, the problem of existing fixed handle drive assemblies being unable to be disassembled and occupying a large space is solved. When not in use, the handle drive assembly can be removed and stored separately, reducing the overall space occupied by the ball valve, facilitating storage and transportation, and avoiding damage to the handle drive assembly due to collision during transportation.

[0016] 2. The rod of this utility model is made of lightweight and high-strength aluminum alloy, which significantly reduces the weight compared to traditional steel materials. At the same time, the rotating wheel is made of high-strength engineering plastic, which reduces the weight of the overall handle drive assembly. In subsequent operation, the light weight of the handle drive assembly itself can effectively reduce the overall weight of the ball valve, realizing the lightweight design of the ball valve, which is convenient for storage, transportation and installation.

[0017] 3. This utility model can adapt to the operating space requirements under different working conditions. When the ball valve is installed in a narrow area or complex pipeline layout, the user can shorten the length of the rod according to the actual installation position to avoid interference with surrounding components. In scenarios where it is necessary to increase the operating torque or control remotely, extending the length of the rod 1 can effectively improve the convenience of operation and reduce the force exerted by the operator.

[0025] like Figure 1-5 As shown, this utility model provides a detachable handle drive assembly for a ball valve, including a rod 1 and a rotary wheel 2 located at the top of the rod 1. The bottom end of the rod 1 is connected to the ball valve drive shaft via a quick-release structure 3 (when the drive shaft rotates, it will synchronously drive the ball inside the ball valve to rotate synchronously, thereby realizing the opening or closing of the ball valve).

[0026] The quick-release structure 3 includes a connecting block 301 fixed at the bottom of the rod 1 and a connecting slot 302 fixed at the top of the ball valve drive shaft. The connecting slot 302 has circular through slots A303 on both sides. The connecting block 301 has an elastic component 305 installed inside to push two circular blocks 304 to move to both sides.

[0027] When the handle drive assembly needs to be installed, insert the connecting block 301 at the bottom of the lever 1 into the connecting slot 302 on the ball valve drive shaft. After insertion, under the elastic thrust of the elastic component 305, the circular block 304 moves outward and engages in the circular through slot A303, making the connecting block 301 and the connecting slot 302 stably connected. This achieves the fixation of the lever 1 to the ball valve drive shaft through the quick-release structure 3. At this time, rotating the rotating wheel 2 drives the lever 1 and the drive shaft to rotate, thereby driving the ball valve to open and close. When the handle drive assembly needs to be disassembled... Press the circular block 304 inward to make it retract into the connecting block 301 against the thrust of the elastic component 305, and the connecting block 301 can be pulled off the connecting slot 302, realizing the quick disassembly and assembly of the handle drive assembly. Through the design of the quick-release structure 3, the problem of existing fixed handle drive assemblies being unable to be disassembled and occupying a large space is solved. When not in use, the handle drive assembly can be removed and stored separately, reducing the overall space occupied by the ball valve, facilitating storage and transportation, and avoiding damage to the handle drive assembly due to collision during transportation.

[0028] The stem 1 is made of lightweight, high-strength aluminum alloy, which significantly reduces the weight compared to traditional steel. Meanwhile, the wheel 2 is made of high-strength engineering plastic, which reduces the overall weight of the handle drive assembly. As a result, the lightweight handle drive assembly effectively reduces the overall weight of the ball valve during subsequent operation, achieving a lightweight design that facilitates storage, transportation, and installation.

[0029] The interior of the connecting block 301 is hollow. Its base plate 3011 is detachably connected to the connecting block 301 by screws. Connecting plates 3014 are slidably connected to both sides of the interior of the connecting block 301. An elastic component 305 is installed between the two connecting plates 3014. A circular block 304 is fixed to the surface of the connecting plate 3014. Circular through slots B3015 are opened on both sides of the connecting block 301 for the circular block 304 to pass through the interior of the connecting block 301. A convex groove 3016 is opened on each of the connecting plates 3014. The elastic component 305 includes two mounting blocks 3051 that can be inserted into the convex groove 3016, and a spring 3052 is installed between the mounting blocks 3051. Guide rails A3012 for sliding sliders A3013 are fixedly connected to the upper and lower sides of the interior of the connecting block 301. The connecting plate 3014 is fixed between the upper and lower sliders A3013.

[0030] Remove the bottom plate 3011 from the bottom of the connecting block 301, insert the mounting block 3051 into the convex groove 3016 on the connecting plate 3014, and then place the spring 3052 between the connecting plates 3014. Next, install the bottom plate 3011. The bottom plate 3011, by pressing against the bottom surface of the mounting block 3051, will confine the mounting block 3051 within the convex groove 3016. At this time, the spring 3052, through its elastic force, will push the two connecting plates 3014 inside the connecting block 301 to move to both sides, thereby removing the circular block 304 from the connecting block 301. The circular through-slot B3015 extends out. When the connecting block 301 is inserted into the connecting slot seat 302, it is blocked by the circular block 304. The upper area of ​​the circular block 304 is pressed down, pushing the circular block 304 into the connecting block 301. The circular block 304 drives the two connecting plates 3014 to move towards the middle, thereby compressing the spring 3052 between the connecting plates 3014. It should be noted that when the connecting plate 3014 moves, it will drive the slider A3013 to move. The slider A3013 slides along the guide rail A3012 to maintain the linear movement of the connecting plate 3014. When the circular block 304 is fully inserted into the connecting slot 302, the circular through slots A303 and B3015 are aligned. Without the obstruction of the side wall of the connecting slot 302, the circular block 304 can be reset under the action of the spring 3052, thus passing through the circular through slot B3015 on the connecting block 301 and exiting from the circular through slot A303 on the connecting slot 302. This achieves the connection between the handle drive assembly and the ball valve drive shaft. Conversely, pressing the circular block 304 again to insert it into the connecting block 301 allows the connecting block 301 to be pulled out of the connecting slot 302, thereby completing the handle drive assembly connection. The disassembly and assembly of the moving component are relatively convenient. When the spring 3052 component is damaged, the bottom plate 3011 at the bottom of the connecting block 301 can be removed again, and the mounting block 3051 can be pulled out from the convex groove 3016 on the connecting plate 3014 to disassemble the elastic component 305, so that it can be replaced when the elastic component 305 is damaged. (The mounting block 3051 has a groove with a handle in it. This recessed handle installation does not occupy the installation space of the handle, and the operator can also easily pull the mounting block 3051 out from the connecting plate 3014 through the handle.)

[0031] Furthermore, the length of the rod 1 is adjustable to adapt to the operating space requirements under different working conditions. When the ball valve is installed in a narrow area or complex pipeline layout, the user can shorten the length of the rod 1 according to the actual installation position to avoid interference with surrounding components. In scenarios where increased operating torque or remote control is required, extending the length of the rod 1 can effectively improve the ease of operation and reduce the force exerted by the operator. The following is the specific structure for adjusting the length of the rod 1: The rod 1 includes an outer rod 101 connected to the connecting block 301 and an inner rod 102 connected to the rotating wheel 2. The inner rod 102 slides along the inside of the outer rod 101. Multiple screw holes 103 are distributed in a vertical array around the outer side wall of the inner rod 102, and through holes 104 are opened at the upper part of the outer side wall of the outer rod 101.

[0032] That is, the inner rod 102 is pulled up and down along the inside of the outer rod 101 to adjust the height of the rod 1. After the height adjustment is completed, the screw is inserted into the corresponding screw hole 103 on the inner rod 102 by passing through the through hole 104 on the outer rod 101 and rotating clockwise, thereby completing the fixation between the outer rod 101 and the inner rod 102, and thus fixing the height of the rod 1.

[0033] Furthermore, a disc 105 is fixedly connected to the bottom end of the outer rod 101 below the through hole 104. Guide rails B106 for sliding the slider B107 are fixedly connected to the top circumference of the disc 105. A bearing 108 is fixedly connected to the top of the slider B107. A screw 109 is fixedly connected to the inner ring of the bearing 108, and a rotating plate 110 is fixedly connected to the head of the screw 109. After the height of the rod 1 is adjusted, the rotating plate 110 pushes the screw 109 to move towards the outer rod 101. The screw 109 drives the bearing 108 to move, which in turn drives the slider B107 to move. The slider B107 slides along the guide rails B106, thus allowing the screw 109 to pass through the through hole 104 on the outer rod 101 and abut against the corresponding height on the inner rod 102. The screw 109 is inserted into the screw hole 103 by rotating the rotating plate 110 clockwise. The screw 109 is then installed into the screw hole 103. When the screw 109 rotates, it drives the inner ring of the bearing 108 to rotate. The inner ring of the bearing 108 rotates along with its outer ring, thereby providing rotational support for the screw 109 through the bearing 108. By rotating the screw 109 into the screw hole 103, the inner rod 102 and the outer rod 101 can be fixed together. Conversely, by rotating the screw 109 clockwise through the rotating plate 110, the screw 109 can be removed from the screw hole 103, thereby releasing the fixation between the outer rod 101 and the inner rod 102. In this way, the screw 109 (which is equivalent to the shank 1 of a screw) is connected to the disc 105 by moving and rotating the components, thus avoiding the problem of losing the screw.
