Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, and in particular to a high wear-resistant wafer butterfly valve. Background Technology

[0002] A clamp-on butterfly valve is a type of valve used for fluid control in pipelines. Its key feature is that it uses a butterfly-shaped valve plate that rotates along a shaft to open and close. Clamp-on butterfly valves are widely used in water treatment, chemical, HVAC, fire protection, and other industrial pipelines, and are particularly suitable for applications requiring frequent opening and closing operations, effectively improving system efficiency and energy savings.

[0003] However, traditional wafer-type butterfly valves are usually installed on the pipeline using bolts. When disassembling, the bolts need to be tightened or loosened one by one. At the same time, the stability of the butterfly valve must be ensured during installation to prevent displacement. This installation method is too inefficient and difficult for one person to perform. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly wear-resistant wafer-type butterfly valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high wear-resistant wafer-type butterfly valve includes a butterfly valve body, a fixing mechanism fixedly connected to the outer wall of the butterfly valve body, a control box fixedly connected to the top of the butterfly valve body, a worm gear rotatably connected to the top of the torque-increasing mechanism, a worm rotatably connected to one side of the control box, and a torque-increasing mechanism rotatably connected to one end of the worm.

[0007] As a further embodiment of this utility model: a valve stem is fixedly connected to the bottom of the worm gear, a rubber ring is fixedly connected to the inner wall of the butterfly valve body, a valve plate is interference-fitted to the inner wall of the rubber ring, and the valve stem passes through the bottom of the control box and is fixedly connected to the valve plate. A handwheel is fixedly connected to one side of the torque-increasing mechanism, and washers are installed on both sides of the butterfly valve body.

[0008] As a further embodiment of this utility model: the torque-increasing mechanism includes a fixed disc, a gripper, a rubber block, a large gear, a guide post, a drive gear, a connecting seat, a second worm gear, a second worm, and a motor, with the fixed disc sleeved on the outer wall of the butterfly valve body.

[0009] As a further embodiment of this utility model: the fixed disk has a groove, the gripper is inserted into the groove of the fixed disk, the rubber block is fixedly connected to one side of the gripper, the large gear is rotatably connected to one side of the fixed disk, the large gear has a guide groove on one side, the guide post is fixedly connected to one side of the gripper, and the guide post and the guide groove are slidably engaged.

[0010] As a further embodiment of this utility model: the connecting seat is fixedly connected to the outer surface of the fixed disk, the drive gear is rotatably connected to one side of the connecting seat, the rotating rod passes through one side of the connecting seat, and the second worm gear is sleeved on the outer wall of the rotating rod, the motor is fixedly connected to one side of the connecting seat, and the motor rotating shaft passes through one side of the connecting seat, the second worm is fixedly connected to the motor rotating shaft, and the second worm meshes with the second worm gear.

[0011] As a further embodiment of this utility model: the torque-increasing mechanism includes a planetary carrier, a gear ring, a connecting block, planetary gears and a sun gear, and one end of the planetary carrier is fixedly connected to one side of the worm gear.

[0012] As a further embodiment of this utility model: the connecting block is fixedly connected to one side of the control box, the gear ring is fixedly connected to one side of the connecting block, the planetary gear is rotatably connected to one end of the planetary carrier, and the planetary gear meshes with the gear ring, and the connecting block is rotatably connected to the sun gear, and the sun gear is fixedly connected to one end of the sun gear.

[0013] Compared with the prior art, this utility model provides a highly wear-resistant wafer-type butterfly valve, which has the following beneficial effects:

[0014] 1. This high wear-resistant wafer-type butterfly valve, when installed, aligns the valve body with the pipeline, then contacts the gasket on one side of the pipeline. At this time, the control fixing mechanism firmly fixes the valve body to the pipeline, and the worm gear and worm wheel mesh. When it is necessary to control the opening or closing of the valve body, the handwheel is turned. The force of the handwheel rotation is amplified by the torque amplification mechanism and then transmitted to the worm gear to rotate. At the same time, the rotation of the worm gear is transmitted to the meshing worm wheel, causing the worm wheel to rotate. Finally, the rotation of the worm wheel is transmitted through the valve stem to the valve plate that is interference-fitted with the rubber ring, realizing the opening and closing of the butterfly valve body. Thus, the wear-resistant properties of the rubber ring reduce the friction loss when the valve plate rotates, extending the service life of the valve. At the same time, the torque amplification mechanism amplifies the torque input to the handwheel, reducing the manual operation intensity. Even for large-diameter or high-pressure industrial control, the handwheel can be turned relatively easily.

[0015] 2. This high-wear-resistant wafer-type butterfly valve, after the butterfly valve body is manually attached to the pipeline, the motor is turned on. The motor's rotating shaft drives the worm gear two to rotate, which in turn drives the worm wheel two to rotate. The worm wheel two drives the rotating rod to rotate, and the rotating rod drives the drive gear to rotate synchronously. At this time, because the drive gear meshes with the large gear, the large gear rotates. When the large gear rotates, the guide post moves along the guide groove and pushes the clamping jaws out of the groove of the fixed plate. Then, the washer is manually pressed against the pipeline. At this time, the motor is reversed, the clamping jaws retract, and the rubber block on one side of the clamping jaws contacts the pipeline, quickly fixing the butterfly valve body to the pipeline. Thus, manual tightening is not required, which greatly shortens the fixing time of the butterfly valve to the pipeline and improves installation efficiency. The rubber block on one side of the clamping jaws provides cushioning during fixing, avoiding hard contact between the clamping jaws and the pipeline that would cause wear, while also enhancing the sealing effect and preventing scratches on the pipeline surface.

[0016] 3. This high wear-resistant wafer-type butterfly valve, when the main body of the butterfly valve needs to be opened or closed, the handwheel is turned, the handwheel drives the sun gear to rotate, and then the sun gear meshes with the planetary gear, driving the planetary gear to roll in the gear ring. The gear ring rotates around its own axis and revolves around the sun gear. The revolution of the planetary gear drives the planetary carrier to rotate. The planetary carrier transmits the amplified torque to the worm gear, which finally drives the worm wheel, valve stem and valve plate to complete the opening and closing action. Thus, the input torque is significantly amplified, the handwheel operating force is reduced, the labor saving effect is achieved, and the stability of valve operation is improved.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] A highly wear-resistant wafer butterfly valve, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 ,and Figure 5 As shown, the device includes a butterfly valve body 1. A fixing mechanism 2 is fixedly connected to the outer wall of the butterfly valve body 1. A control box 3 is fixedly connected to the top of the butterfly valve body 1. A worm gear 9 is rotatably connected to the top of the torque-increasing mechanism 4. A worm 8 is rotatably connected to one side of the control box 3. A valve stem is fixedly connected to the bottom of the worm gear 9. A rubber ring 6 is fixedly connected to the inner wall of the butterfly valve body 1. A valve plate 7 is interference-fitted to the inner wall of the rubber ring 6. The valve stem passes through the bottom of the control box 3 and is fixedly connected to the valve plate 7. A torque-increasing mechanism 4 is rotatably connected to one end of the worm 8. A handwheel 5 is fixedly connected to one side of the torque-increasing mechanism 4. Washers are installed on both sides of the butterfly valve body 1.

[0028] When a butterfly valve needs to be installed, align the butterfly valve body 1 with the pipeline, and then make the gasket contact one side of the pipeline. At this time, the control fixing mechanism 2 firmly fixes the butterfly valve body 1 to the pipeline, and the worm gear 8 meshes with the worm wheel 9.

[0029] When it is necessary to control the opening or closing of the butterfly valve body 1, the handwheel 5 is turned. The force of the handwheel 5 rotation is amplified by the torque amplification mechanism 4 and then transmitted to the worm gear 8 for rotation. At the same time, the rotation of the worm gear 8 is transmitted to the worm wheel 9 meshing with it, causing the worm wheel 9 to rotate. Finally, the rotation of the worm wheel 9 is transmitted through the valve stem to the valve plate 7, which is interference-fitted with the rubber ring 6, thereby realizing the opening and closing of the butterfly valve body 1. Thus, the wear-resistant properties of the rubber ring 6 reduce the friction loss when the valve plate 7 rotates, extending the service life of the valve. At the same time, the torque amplification mechanism 4 amplifies the torque input to the handwheel 5, reducing the manual operation intensity. Even when facing large-diameter or high-pressure industrial control, the handwheel 5 can be turned relatively easily.

[0030] To quickly secure the butterfly valve body 1 to the pipeline, such as Figure 3 As shown, the torque-increasing mechanism 4 includes a fixed disk 201, a gripper 202, a rubber block 203, a large gear 204, a guide post 205, a drive gear 206, a connecting seat 207, a second worm gear 208, a second worm 209, and a motor 210. The fixed disk 201 is sleeved on the outer wall of the butterfly valve body 1, and the fixed disk 201 has a groove. The gripper 202 is inserted into the groove of the fixed disk 201. The rubber block 203 is fixedly connected to one side of the gripper 202. The large gear 204 is rotatably connected to one side of the fixed disk 201, and a guide groove is provided on one side of the large gear 204. The guide post 205 is fixedly connected to one side of the gripper 202, and the guide post 205 is slidably engaged with the guide groove. The connecting seat 207 is fixedly connected to the outer surface of the fixed disk 201. The drive gear 206 is rotatably connected to one side of the connecting seat 207. The rotating rod passes through one side of the connecting seat 207, and the second worm gear 208 is sleeved on the outer wall of the rotating rod. The motor 210 is fixedly connected to one side of the connecting seat 207, and the rotating shaft of the motor 210 passes through one side of the connecting seat 207. The second worm gear 209 is fixedly connected to the rotating shaft of the motor 210, and the second worm gear 209 meshes with the second worm gear 208.

[0031] When the butterfly valve body 1 is manually engaged with the pipeline, the motor 210 is turned on. The rotating shaft of the motor 210 drives the worm gear 209 to rotate, which in turn drives the worm wheel 208 to rotate.

[0032] The second worm gear 208 drives the rotating rod to rotate, and the rotating rod drives the drive gear 206 to rotate synchronously. At this time, because the drive gear 206 meshes with the large gear 204, the large gear 204 rotates.

[0033] When the large gear 204 rotates, the guide post 205 moves along the guide groove and pushes the clamp 202 out of the groove of the fixed plate 201. Then, the washer is manually pressed against the pipeline. At this time, the motor 210 is reversed, the clamp 202 retracts and the rubber block 203 on one side of the clamp 202 contacts the pipeline, quickly fixing the butterfly valve body 1 to the pipeline. Thus, manual tightening is not required, which greatly shortens the fixing time of the butterfly valve and the pipeline and improves the installation efficiency. The rubber block 203 on one side of the clamp 202 provides a buffer during fixing, avoiding hard contact between the clamp 202 and the pipeline and causing wear. At the same time, it enhances the sealing effect and prevents the pipeline surface from being scratched.

[0034] To increase the torque of handwheel 5, such as Figure 5 As shown, the torque-increasing mechanism 4 includes a planetary carrier 401, a gear ring 402, a connecting block 403, a planetary gear 404, and a sun gear 405. One end of the planetary carrier 401 is fixedly connected to one side of the worm gear 8, the connecting block 403 is fixedly connected to one side of the control box 3, the gear ring 402 is fixedly connected to one side of the connecting block 403, the planetary gear 404 is rotatably connected to one end of the planetary carrier 401, and the planetary gear 404 meshes with the gear ring 402. The connecting block 403 is rotatably connected to the sun gear 405, and the sun gear 405 is fixedly connected to one end of the sun gear 405.

[0035] When it is necessary to open or close the butterfly valve body 1, turn the handwheel 5. The handwheel 5 drives the sun gear 405 to rotate. Then, when the sun gear 405 rotates, it meshes with the planet gear 404, driving the planet gear 404 to roll in the gear ring 402. The gear ring 402 rotates around its own axis and revolves around the sun gear 405.

[0036] The revolution of the planetary gear 404 drives the planetary carrier 401 to rotate. The planetary carrier 401 transmits the amplified torque to the worm gear 8, which in turn drives the worm wheel 9, valve stem, and valve plate 7 to complete the opening and closing action. This significantly amplifies the input torque, reduces the operating force of the handwheel 5, achieves a labor-saving effect, and improves the stability of valve operation.

[0037] Work process: When a butterfly valve needs to be installed, align the butterfly valve body 1 with the pipeline, and then make the gasket contact one side of the pipeline. At this time, the control fixing mechanism 2 firmly fixes the butterfly valve body 1 to the pipeline, and the worm gear 8 and the worm wheel 9 mesh.

[0038] When it is necessary to control the opening or closing of the butterfly valve body 1, the handwheel 5 is turned. The force of the handwheel 5 rotation is amplified by the torque amplification mechanism 4 and then transmitted to the worm gear 8 for rotation. At the same time, the rotation of the worm gear 8 is transmitted to the worm wheel 9 meshing with it, causing the worm wheel 9 to rotate. Finally, the rotation of the worm wheel 9 is transmitted through the valve stem to the valve plate 7, which is interference-fitted with the rubber ring 6, thereby realizing the opening and closing of the butterfly valve body 1.

[0039] When the butterfly valve body 1 is manually engaged with the pipeline, the motor 210 is turned on. The rotating shaft of the motor 210 drives the worm gear 209 to rotate, which in turn drives the worm wheel 208 to rotate.

[0040] The second worm gear 208 drives the rotating rod to rotate, and the rotating rod drives the drive gear 206 to rotate synchronously. At this time, because the drive gear 206 meshes with the large gear 204, the large gear 204 rotates.

[0041] When the large gear 204 rotates, the guide post 205 moves along the guide groove and pushes the gripper 202 out of the groove of the fixed plate 201. Then, the washer is manually pressed against the pipe. At this time, the motor 210 is reversed, the gripper 202 retracts and the rubber block 203 on one side of the gripper 202 contacts the pipe, quickly fixing the butterfly valve body 1 to the pipe.

[0042] When it is necessary to open or close the butterfly valve body 1, turn the handwheel 5. The handwheel 5 drives the sun gear 405 to rotate. Then, when the sun gear 405 rotates, it meshes with the planet gear 404, driving the planet gear 404 to roll in the gear ring 402. The gear ring 402 rotates around its own axis and revolves around the sun gear 405.

[0043] The revolution of the planetary gear 404 drives the planetary carrier 401 to rotate. The planetary carrier 401 transmits the amplified torque to the worm gear 8, which in turn drives the worm wheel 9, valve stem and valve plate 7 to complete the opening and closing action.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
