Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, specifically to an elastic ball butterfly valve. Background Technology

[0002] Butterfly valves are one of the most common types of valves. They mainly consist of a valve body, valve stem, butterfly plate, and sealing ring. A butterfly valve is a type of valve whose closing element (valve disc or butterfly plate) is a disc that rotates around the valve shaft to open and close. It can prevent the leakage of liquids or gases in pipelines and more effectively protect equipment and pipeline systems.

[0003] Currently, butterfly valves lack auxiliary elastic support mechanisms. Typically, the inlet and outlet of a butterfly valve are connected to the pipeline via flanges. However, butterfly valves are mostly suspended structures, and when fluid passes through them, vibrations can easily occur, affecting the stability of the connection and potentially causing the interface to loosen over time. Therefore, a flexible ball butterfly valve is proposed to add an auxiliary elastic support mechanism. By using a sleeve and support method, the stability of the ball butterfly valve during processing is improved, making it less susceptible to vibrations caused by fluid flow. This also improves the assembly and usage quality of the butterfly valve, thereby enhancing its performance. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides an elastic ball butterfly valve, which utilizes a sleeve and support method to improve the stability of the ball butterfly valve during processing, thereby improving its performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is an elastic ball butterfly valve, including a valve body, a sleeve and a support assembly. The valve body is sleeved around its periphery, and the bottom of the sleeve is provided with a support assembly.

[0006] The support assembly includes a pad, a threaded sleeve is bolted to the top of the pad, a threaded rod is threaded to the top of the threaded sleeve, an arc-shaped slider is bolted to one end of the threaded rod, and an elastic pad is glued to the bottom of the pad.

[0007] By adopting the above technical solution, an auxiliary support mechanism can be added. By using the sleeve and support method, a shock-absorbing and protective structure can be formed on the periphery of the butterfly valve, thereby improving the stability of the butterfly valve during operation.

[0008] Specifically, the valve body includes pipes, and a ball is rotatably connected between the pipes. A channel is opened in the ball, and a filter plate is arranged in the channel. The filter plate includes filter holes.

[0009] By adopting the above technical solution, an auxiliary filtration mechanism can be added, which can enhance the functionality of the butterfly valve and improve the quality of fluid delivery through filtration.

[0010] Specifically, the bottom surface of the sheath has an arc-shaped slide, and the surface of the sheath has a through hole.

[0011] By adopting the above technical solution, the arc-shaped slide rail facilitates sliding displacement in conjunction with the arc-shaped slider, and the through hole allows operators to observe the residual impurities in the valve body.

[0012] The beneficial effects of this utility model are:

[0013] The elastic ball butterfly valve described in this utility model, through the setting of a protective sleeve, a pad, a threaded sleeve, a threaded rod, an arc-shaped slider and an elastic pad, can increase the auxiliary support mechanism. By using the sleeve and support method, a shock-absorbing and protective structure is formed on the periphery of the butterfly valve, which improves the stability of the butterfly valve during operation and greatly reduces the vibration generated when the fluid passes through the butterfly valve, making it more stable and reliable in use.

[0014] The elastic ball butterfly valve described in this utility model, through the setting of valve body, pipe, ball, channel, filter plate and filter hole, can increase the auxiliary filtration mechanism, increase the functionality of the butterfly valve by filtration, reduce impurities in the fluid, improve the performance of the butterfly valve, and make it more reasonable and practical to use.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To facilitate the use of sleeves and supports to improve the stability of ball butterfly valves during manufacturing, thereby enhancing their performance, such as... Figure 1-3 As shown, the elastic ball butterfly valve of this utility model includes a valve body 1, a sleeve 2 and a support assembly 3. The sleeve 2 is sleeved around the valve body 1, and the support assembly 3 is provided at the bottom of the sleeve 2.

[0025] The support assembly 3 includes a pad 301, the top of the pad 301 is bolted to a threaded sleeve 302, the top of the threaded sleeve 302 is threaded to a threaded rod 303, one end of the threaded rod 303 is bolted to an arc-shaped slider 304, and the bottom of the pad 301 is glued to an elastic pad 305.

[0026] During use, the auxiliary support mechanism can be added through the sleeve 2, pad 301, threaded sleeve 302, threaded rod 303, arc-shaped slider 304 and elastic pad 305. By using the sleeve and support method, a shock-absorbing and protective structure is formed on the periphery of the butterfly valve, which improves the stability of the butterfly valve during operation.

[0027] Both the sheath 2 and the elastic pad 305 are made of rubber.

[0028] To improve the quality of fluid flow, for example, such as Figure 4 , Figure 5 As shown, the present invention also includes a valve body 1 comprising a pipe 101, a ball 102 rotatably connected between the pipes 101, a channel 103 opened in the ball 102, a filter plate 104 disposed in the channel 103, and the filter plate 104 comprising filter holes 105.

[0029] In use, an auxiliary filtration mechanism can be added through pipe 101, ball 102, channel 103, filter plate 104 and filter hole 105. By using filtration, the functionality of the butterfly valve is increased, and the quality of fluid delivery is improved.

[0030] For example, such as Figure 3 As shown, the present invention also includes an arc-shaped slide 201 on the bottom surface of the sheath 2 and a through hole 202 on the surface of the sheath 2.

[0031] During use, the arc-shaped slide 201 facilitates sliding displacement in conjunction with the arc-shaped slider 304, and the through hole 202 allows the operator to observe the residual impurities inside the valve body 1.

[0032] For example, such as Figure 5 As shown, the present invention also includes an elastic ring 106 disposed around the filter plate 104, and a slot 107 corresponding to the elastic ring 106 is provided in the channel 103.

[0033] During use, the elastic ring 106 and the slot 107 facilitate the operator to disassemble and install the filter plate 104 for maintenance.

[0034] For example, such as Figure 4 As shown, the present invention also includes a valve stem 109 connected to the top of the valve body 1 by a thread, and one end of the valve stem 109 is connected to a ball 102 by a bolt. A handle 110 is provided on the top of the valve stem 109, and a sealing gasket 108 is provided inside the pipe 101 around the ball 102.

[0035] In use, the valve stem 109 and the handle 110 can drive the ball 102 to open and close, and the sealing gasket 108 can help improve the sealing performance of the butterfly valve when closed.

[0036] For example, such as Figure 6 As shown, the present invention also includes a sealing cover 4 corresponding to the ball 102 connected to the surface of the valve body 1 by a thread, and the sealing cover 4 includes a transparent window 401.

[0037] During use, the sealing cover 4 and the transparent window 401 facilitate improved sealing when the valve body 1 is working, and also make it convenient for subsequent operators to clean the filtered impurities.

[0038] In use, the operator first connects the connecting pipes 101 at both ends of the valve body 1 via flanges. Then, based on the distance and height of the bottom of the valve body 1, the threaded sleeve 302 and the pad 301 are rotated, and the threaded rod 303 is connected by threads so that the pad 301 can contact the ground. With the support of the pad 301, the threaded sleeve 302 and the threaded rod 303, the valve body 1 can be prevented from being suspended during operation. At the same time, the elastic pad 305 and the elastic sleeve 2 can play an auxiliary shock absorption role, reducing the vibration generated by the butterfly valve when fluid passes through and improving the stability of operation.

[0039] Furthermore, when the handle 110 is manually turned, the valve stem 109 drives the ball 102 to rotate, thus connecting the pipe 101 with the channel 103 of the ball 102 to form a passage. When the fluid passes through the channel 103, the filter plate 104 and filter holes 105 can play an auxiliary filtration role, improving the quality of fluid delivery and increasing the functionality of the butterfly valve. In addition, the operator can periodically remove the sealing cover 4 to clean the impurities remaining in the ball 102 while the valve body 1 is closed. The overall structure is simple and the use is more stable and reliable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
