Description

Technical Field

[0001] The present application relates to the technical field of butterfly valves, and in particular to a new type of butterfly valve. Background Art

[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve that can be used for the on-off control of low-pressure pipeline media. The butterfly valve refers to a valve whose closing part (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve opening and closing. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays a role of cutting off and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulating.

[0003] Existing butterfly valves are generally positioned and installed with a large number of bolts. It is troublesome to use bolts to position the butterfly valve. Not only is the installation laborious, but it is also inconvenient to disassemble and maintain the butterfly valve, which reduces the flexibility and practicality of the butterfly valve and increases the workload of workers. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a new type of butterfly valve, which has the advantages of convenient installation and positioning of the butterfly valve, as well as convenient disassembly and maintenance of the butterfly valve, and improved flexibility and practicality of the butterfly valve. It solves the problem that the existing butterfly valves are generally positioned and installed with a large number of bolts, and it is troublesome to use bolts to position the butterfly valve, which is not only laborious to install, but also inconvenient to disassemble and maintain the butterfly valve, reducing the flexibility and practicality of the butterfly valve and increasing the workload of workers.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a new type of butterfly valve, comprising a valve body, the inner wall of the valve body is slidably connected to two pipes, the outer circumferential surface of the valve body is fixedly sleeved with two fixing rings, the interior of each of the fixing rings is fixedly connected to an equidistantly arranged fixing seat, the interior of each of the fixing seats is rotatably inserted with a threaded rod, the outer circumferential surface of the threaded rod is threadedly connected to a threaded pipe, the side of the threaded pipe away from the threaded rod is fixedly connected to a fixing frame, the inner wall of the fixing frame is slidably connected to a positioning block, the outer circumferential surface of each of the pipes is fixedly sleeved with a positioning plate, and the interior of the positioning plate is provided with equidistantly arranged positioning grooves.

[0006] Through the above scheme, since the existing butterfly valves are generally positioned and installed with a large number of bolts, it is troublesome to use bolts to position the butterfly valve. Not only is the installation laborious, but it is also inconvenient to disassemble and maintain the butterfly valve, reducing the flexibility and practicality of the butterfly valve. During the rotation of the gear ring, the threaded rod is driven to rotate under the action of the gear, prompting the threaded pipe to drive the fixed frame and the positioning block to move, thereby directly completing the installation and positioning of the valve body and the pipeline, facilitating the disassembly and maintenance of the butterfly valve, and reducing the workload of workers.

[0007] Furthermore, two sealing strips are fixedly connected to the interior of the valve body, and the sides of the two sealing strips close to the pipeline are in contact with one side of the pipeline respectively.

[0008] Through the above solution, the valve body and the pipeline are sealed to prevent liquid from overflowing and leaking from the gap between the valve body and the pipeline.

[0009] Furthermore, the bottom surface of the positioning block is an inclined surface, the upper surface of the positioning block is fixedly connected with a spring, and the top end of the spring is fixedly connected to the inner top wall of the fixed frame.

[0010] Through the above scheme, the positioning block can be lifted when the inclined surface is subjected to force, and automatically move back under the action of the spring, so as to facilitate the docking installation of the pipeline and the valve body.

[0011] Furthermore, a sliding rod is fixedly connected to the upper surface of the positioning block, the outer circumferential surface of the sliding rod is slidably inserted into the interior of the fixed frame, and a collar is fixedly sleeved on the outer circumferential surface of the sliding rod.

[0012] Through the above solution, the positioning block is restricted to prevent the positioning block from easily slipping out of the fixing frame, thereby increasing the stability of the positioning block.

[0013] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the threaded rod, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the fixing seat.

[0014] Through the above solution, the threaded rod is restricted to prevent the threaded rod from sliding and deviating, thereby increasing the stability of the threaded rod movement.

[0015] Furthermore, the outer circumferential surface of the threaded tube is fixedly connected to a limit plate, and the outer surface of the limit plate is slidably connected to the inside of the fixing seat.

[0016] Through the above solution, the threaded tube is restricted to prevent the threaded tube from rotating along with the threaded rod, thereby increasing the stability of the threaded tube movement.

[0017] Furthermore, a gear is fixedly sleeved on the outer circumferential surface of the threaded rod, and the outer circumferential surface of the valve body is rotatably connected to two gear rings, the gears are meshed with the gear rings, and the outer surface of each gear ring is fixedly connected to a handle, and the inner wall of the handle is rotatably sleeved on the outer circumferential surface of the valve body.

[0018] Through the above scheme, the rotating handle can drive the gear to rotate through the gear ring, thereby causing all the threaded rods to rotate synchronously, thereby directly completing the positioning connection between the valve body and the pipeline.

[0019] Furthermore, an auxiliary rod is fixedly inserted inside the positioning plate, and an auxiliary groove is opened inside each of the fixing rings, and the auxiliary rod is slidably inserted into the fixing ring through the auxiliary groove.

[0020] Through the above scheme, the auxiliary pipeline of the auxiliary rod and the auxiliary groove can be connected with the valve body, so that the positioning block and the positioning groove can be conveniently connected and installed.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This new butterfly valve, through the rotation of the gear ring, drives the threaded rod to rotate under the action of the gear, prompting the threaded pipe to drive the fixed frame and the positioning block to move, so as to directly complete the installation and positioning of the valve body and the pipeline, facilitate the disassembly and maintenance of the butterfly valve, and reduce the workload of workers. It solves the problem that the existing butterfly valve is generally positioned and installed with a large number of bolts, which is not only laborious to install but also inconvenient to disassemble and maintain the butterfly valve.

[0031] See also Figure 2 Two sealing strips 3 are fixedly connected to the inside of the valve body 1. The sides of the two sealing strips 3 close to the pipeline 2 are in contact with one side of the pipeline 2 respectively, so as to seal the valve body 1 and the pipeline 2 to prevent the liquid from overflowing and leaking from the gap between the valve body 1 and the pipeline 2.

[0032] See also Figure 1 , Figure 2 and Figure 3 The bottom surface of the positioning block 9 is an inclined surface, and a spring 10 is fixedly connected to the upper surface of the positioning block 9. The top end of the spring 10 is fixedly connected to the inner top wall of the fixed frame 8, so that the positioning block 9 can be lifted when the inclined surface is subjected to force, and automatically move back under the action of the spring 10, so as to facilitate the docking and installation of the pipeline 2 and the valve body 1.

[0033] See also Figure 1 , Figure 2 and Figure 3 The upper surface of the positioning block 9 is fixedly connected with a sliding rod 11, and the outer circumferential surface of the sliding rod 11 is slidably inserted into the interior of the fixed frame 8. The outer circumferential surface of the sliding rod 11 is fixedly sleeved with a ring 12 to limit the positioning block 9, prevent the positioning block 9 from easily slipping out of the fixed frame 8, and increase the stability of the positioning block 9.

[0034] See also Figure 3 The outer circumference of the threaded rod 6 is fixedly sleeved with a limiting ring 13, and the outer circumference of the limiting ring 13 is rotatably connected to the inside of the fixing seat 5 to limit the threaded rod 6, prevent the threaded rod 6 from sliding and deviating, and increase the stability of the threaded rod 6 movement.

[0035] See also Figure 1 , Figure 2 and Figure 3 The outer circumferential surface of the threaded tube 7 is fixedly connected to a limiting plate 14, and the outer surface of the limiting plate 14 is slidably connected to the inside of the fixing seat 5 to limit the threaded tube 7, prevent the threaded tube 7 from rotating with the threaded rod 6, and increase the stability of the threaded tube 7 movement.

[0036] See also Figure 1 , Figure 2 and Figure 3 A gear 15 is fixedly sleeved on the outer circumference of the threaded rod 6, and two gear rings 16 are rotatably connected to the outer circumference of the valve body 1. The gear 15 is meshed with the gear ring 16, and a handle 17 is fixedly connected to the outer surface of each gear ring 16. The inner wall of the handle 17 is rotatably sleeved on the outer circumference of the valve body 1, so that the rotating handle 17 can drive the gear 15 to rotate through the gear ring 16, thereby making all the threaded rods 6 rotate synchronously, and directly completing the positioning connection between the valve body 1 and the pipeline 2.

[0037] See also Figure 1 An auxiliary rod 20 is fixedly inserted inside the positioning plate 18, and an auxiliary groove 21 is opened inside each fixing ring 4. The auxiliary rod 20 is slidably inserted with the fixing ring 4 through the auxiliary groove 21. The auxiliary pipeline 2 can be connected to the valve body 1 through the auxiliary rod 20 and the auxiliary groove 21, which facilitates the docking installation of the positioning block 9 and the positioning groove 19.

[0038] A new type of butterfly valve in the present embodiment drives the threaded rod 6 to rotate under the action of the gear 15 during the rotation of the gear ring 16, prompting the threaded tube 7 to drive the fixed frame 8 and the positioning block 9 to move, thereby achieving the effect of directly completing the installation and positioning operation of the valve body 1 and the pipeline 2, facilitating the disassembly and maintenance of the butterfly valve, and reducing the workload of workers, and solving the problem that the existing butterfly valve is generally positioned and installed with a large number of bolts, which is not only laborious to install but also inconvenient to disassemble and maintain the butterfly valve.

[0039] It should be noted that the outer circumferential surface of the handle 17 is provided with equidistantly arranged anti-skid grooves to prevent workers from slipping during operation, thereby providing convenience for the workers.

[0040] The working principle of the above embodiment is:

[0041] When it is necessary to install the valve body 1 and the pipeline 2, the pipeline 2 can be inserted into the valve body 1, and the auxiliary rod 20 can be inserted into the auxiliary groove 21. During the installation process, the pipeline 2 will drive the positioning plate 18 to squeeze the inclined surface of the positioning block 9, thereby causing the positioning block 9 to move up inside the fixed frame 8. When the positioning plate 18 moves to the inner side of the positioning block 9, the positioning block 9 will automatically move back under the action of the spring 10, and then the handle 17 is turned to drive the gear ring 16 to rotate, and the gear ring 16 drives the threaded rod 6 to rotate through the gear 15, and the threaded rod 6 drives the fixed frame 8 and the positioning block 9 to move through the threaded tube 7, so that the positioning block 9 moves into the positioning groove 19, and the positioning plate 18 is pressed through the positioning groove 19, thereby positioning the pipeline 2. When it is necessary to disassemble and maintain the butterfly valve, the handle 17 can be rotated in the opposite direction to prompt the positioning block 9 to move back and move out of the positioning groove 19, thereby releasing the positioning restriction on the pipeline 2, and then the pipeline 2 can be separated from the valve body 1.
