Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a butterfly valve that can be quickly assembled and disassembled. Background Art

[0002] A butterfly valve is a common type of valve and plays a key role in many industrial and civil pipeline systems. It mainly consists of a valve body, a valve disc, a valve stem, and a driving device, etc. The valve body is the outer shell of the butterfly valve, providing a basic support framework for the entire valve and forming a fluid passage inside. The valve disc is usually in a disc shape, just like a butterfly, which is also the origin of the name of the butterfly valve. The valve disc is located in the fluid passage inside the valve body and is connected to the driving device through the valve stem. The driving device includes a manual handwheel or electric and pneumatic actuators. The working principle of the butterfly valve is based on the rotational movement of the valve disc. When it is necessary to control the fluid flow rate, by operating the driving device, the valve disc rotates around the central axis of the valve stem. When the valve disc rotates to a position parallel to the fluid passage, the valve is in the fully open state and the fluid can flow smoothly; while when the valve disc rotates to a position perpendicular to the fluid passage, the valve is completely closed, effectively truncating the fluid flow. Due to its many advantages such as simple structure, small volume, and convenient operation, the butterfly valve is widely used in many fields such as water supply and drainage, chemical industry, petroleum, and electric power, and is one of the important devices for pipeline fluid control.

[0003] However, during the assembly process of some existing butterfly valves, various tools are usually required to assist the operation. For example, during the installation process, a wrench is needed to tighten the nuts at the connection parts, or specific fixtures are used to fix some components of the butterfly valve to ensure the accuracy of their installation positions. During disassembly, tools such as screwdrivers are also needed to loosen the tightened screws or disassemble some connection structures. This undoubtedly increases the complexity and difficulty of the operation. It not only makes the entire installation and disassembly process time-consuming and laborious, and the operator needs to spend a lot of time preparing and using tools, but also may cause damage to the components or unsuccessful installation and disassembly due to improper use of the tools. Such cumbersome operation steps not only increase the operation time, but also pose higher requirements on the skills and patience of the operator, are prone to errors during the operation, thereby affecting the installation quality and use effect of the butterfly valve, and also reducing the work efficiency to a certain extent and increasing the maintenance cost and time cost. Therefore, in view of the above deficiencies, a butterfly valve that can be quickly assembled and disassembled is proposed to solve the above problems. Summary of the Utility Model

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figures 1 to 3 , an embodiment provided by the present invention: a butterfly valve that can be quickly assembled and disassembled, including a valve body 1. The valve body 1 is the main body part of the butterfly valve, which plays a role in accommodating and guiding the fluid flow. A rotating handle 2 is provided at the top of the valve body 1. The function of the rotating handle 2 is for the operator to manually operate. By rotating the rotating handle 2, the opening and closing actions of the butterfly valve can be realized, thereby controlling the flow rate and flow direction of the fluid. Docking pipes 3 are fixedly connected to both the left and right sides of the valve body 1. The function of the docking pipes 3 is to connect with external pipelines. Docking rings 4 are fixedly connected to both the left and right sides of the valve body 1. A plurality of fixed rings 5 are fixedly connected to the inside of the two docking rings 4. Elastic force components for providing pressure are provided inside the plurality of fixed rings 5. Each of the plurality of elastic force components includes a sliding rod 6. The fixed ring 5 provides a sliding track and support for the sliding rod 6. The outer parts of the plurality of sliding rods 6 are respectively slidably connected to the inside of the plurality of fixed rings 5. Springs 7 are sleeved on the outer parts of the plurality of sliding rods 6. One end of each spring 7 is fixedly connected to the inside of the docking ring 4, and the other end of each spring 7 is fixedly connected to the side of the fixed ring 5 close to the protective shell 12. The springs 7 provide elastic force. When the connecting pipe 13 is inserted, the clamping plate 16 squeezes the pressure receiving plate 8 to compress the springs 7, and the springs 7 store elastic potential energy. When the clamping plate 16 enters the disc groove 11, the elastic force of the springs 7 is released, making the clamping plate 16 more firmly clamped inside the docking ring 4, ensuring the stability of the connection. Pressure receiving plates 8 are fixedly connected to the adjacent sides of the plurality of sliding rods 6. When assembling the butterfly valve, when the connecting pipe 13 is inserted into the docking ring 4, the clamping plate 16 squeezes the pressure receiving plate 8, and the pressure receiving plate 8 drives the sliding rod 6 to slide inside the fixed ring 5. The movement of the sliding rod 6 transmits the pressure of the clamping plate 16, causing the springs 7 to be compressed.

[0034] Referring to Figure 1 , Figure 2 andFigure 6 Inside both of the two docking rings 4, there are multiple sliding holes 9 opened. The outside of the pressure receiving plate 8 is slidably connected inside the sliding holes 9. Inside both of the two docking rings 4, there are multiple sliding grooves 10 which play a role in guiding and positioning the clamping plate 16 during the assembly of the butterfly valve. Inside both of the two docking rings 4, there are multiple disc grooves 11. After the clamping plate 16 enters the disc groove 11 through the sliding groove 10, by rotating the rotating frame 15, the clamping plate 16 can rotate inside the disc groove 11 and enter the inside of the protective shell 12, thus realizing the clamping of the clamping plate 16 inside the docking ring 4. On the outside of both of the two docking rings 4, there are multiple protective shells 12 fixedly connected. Inside both of the two docking rings 4, there is a connecting pipe 13 slidably connected. The internal channel of the connecting pipe 13 is connected to the channels of the valve body 1 and the external pipeline, ensuring that the fluid can flow smoothly in the pipeline. The outside of the connecting pipe 13 is slidably connected inside the docking ring 4. On the outside of both of the two connecting pipes 13, there is an installation ring 14 fixedly connected. The far sides of the two docking rings 4 are respectively in contact with the near sides of the two installation rings 14. The installation ring 14 provides a basis for the installation and rotation of the rotating frame 15. Inside both of the two installation rings 14, there are multiple rotating frames 15 rotatably connected. On the near sides of the multiple rotating frames 15, there is a clamping plate 16 fixedly connected. By rotating the rotating frame 15, the clamping plate 16 rotates inside the disc groove 11. The outside of the clamping plate 16 is slidably connected inside the sliding groove 10, the outside of the clamping plate 16 is slidably connected inside the disc groove 11, and the outside of the clamping plate 16 is slidably connected inside the protective shell 12.

[0035] Refer to Figures 3 to 5 Inside both of the two docking rings 4, there is a clamping ring 17 fixedly connected. When the connecting pipe 13 is inserted into the docking ring 4, the outside of the connecting pipe 13 and the outside of the docking pipe 3 are both slidably connected inside the sealing groove 18. Through its own structure and the design of the sealing groove 18, the clamping ring 17 conducts preliminary positioning and sealing on the connection between the connecting pipe 13 and the docking pipe 3. On the left and right sides of both of the two clamping rings 17, there is a sealing groove 18 opened. The outside of the docking pipe 3 is slidably connected inside the sealing groove 18, and the outside of the connecting pipe 13 is slidably connected inside the sealing groove 18. When the connecting pipe 13 is inserted into the docking ring 4, the sealing groove 18 can guide the connecting pipe 13 and the docking pipe 3 to be accurately inserted into the corresponding positions, and at the same time, through cooperation with the sealing ring 19, it realizes the full coverage and sealing of the connection. Inside both of the two clamping rings 17, there is a sealing ring 19 fixedly connected. The sealing ring 19 is made of a material with good elasticity and sealing performance. After the connecting pipe 13 and the docking pipe 3 are inserted into the sealing groove 18, the sealing ring 19 is extruded and deformed, filling the gap between the connecting pipe 13 and the docking pipe 3 and the gap between them and the sealing groove 18, thereby effectively preventing the fluid from leaking at the connection.

[0036] Working principle: When installing the butterfly valve, the valve body 1 can be first aligned to the middle of the pipes on both sides, and then the connecting pipe 13 can be slid into the interior of the docking ring 4. At this time, the clamping plate 16 will be aligned with the slide groove 10 and slide into the interior of the docking ring 4. At this time, the clamping plate 16 will squeeze the pressure plate 8 to cause the pressure plate 8 to displace, and then the sliding rod 6 will slide inside the fixed ring 5 and the spring 7 will be compressed and rebounded. When the clamping plate 16 enters the interior of the disc groove 11, the rotating frame 15 can be rotated to make the clamping plate 16 rotate inside the disc groove 11 and enter the interior of the protective shell 12. At this time, the clamping plate 16 will be engaged with the interior of the docking ring 4, and the elastic force of the spring 7 will make the engagement more firm. At this time, the rapid assembly of the valve body 1 is completed. When disassembling, you only need to rotate the rotating frame 15 to make the clamping plate 16 disengage from the interior of the disc groove 11 to complete the rapid disassembly of the valve body 1. As the connecting pipe 13 enters the interior of the docking ring 4, the connecting pipe 13 will slide into the interior of the sealing groove 18, and the connecting portion between the connecting pipe 13 and the valve body 1 will be fully covered by the clamping ring 17 and the sealing ring 19, thereby ensuring the sealing of the connection.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
