Detailed Implementation

[0022] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figure 1 As shown, this utility model proposes a circulating water pipe system for a spray booth, including: a wall 1, butterfly valves 2, and pipes 3. There are several butterfly valves 2, which are distributed and installed on one side of the upper end and one side of the lower end of the wall 1. Adjacent butterfly valves 2 are connected by pipes 3. The butterfly valve 2 includes: a valve body 21, a water flow opening and closing mechanism 22, and a rotation positioning mechanism 23. The valve body 21 has a through hole in the middle, and external water pipes are connected to both sides of the through hole. The water flow opening and closing mechanism 22 is provided in the through hole. The water flow opening and closing mechanism 22 can rotate relative to the through hole. The water flow opening and closing mechanism 22 controls the water flow through the through hole or blocks the water flow through the through hole by rotating. The rotation positioning mechanism 23 is installed on the top of the valve body 21. The rotation positioning mechanism 23 includes: a rotating part 231 and a rotation limiting mechanism 232. The rotating part 231 is connected to the water flow opening and closing mechanism 22. The rotation limiting mechanism 232 is installed next to the rotating part 231 and is used to limit the rotation of the rotating part 232.

[0024] In this embodiment, butterfly valve 2 is installed on wall 1, and adjacent butterfly valves 2 are connected by pipe 3 to form a complete circulation loop. The water flow opening and closing mechanism 22 inside butterfly valve 2 controls the flow of water by rotation, while the rotation positioning mechanism 23 precisely controls the rotation angle through the rotation limiting mechanism 232 to ensure the stability and directionality of the water flow.

[0025] Water circulates between butterfly valve 2 and pipe 3. The precise control of water flow is achieved by adjusting butterfly valve 2, thereby optimizing the utilization of water resources in the spray booth and improving the system's operating efficiency.

[0026] like Figure 2As shown, the valve body 21 further includes: a pipe body 211, an upper mounting seat 212, and a lower mounting seat 213. A through hole is located inside the pipe body 211. Both sides of the pipe body 211 are connected to external water pipes, allowing water to flow through. The upper mounting seat 212 and lower mounting seat 213 are respectively provided on the upper and lower sides of the outer wall of the pipe body 211. The mounting seats are used to fix the pipes to the external water pipes. A water flow opening and closing mechanism 22 is provided in the pipe body 211. The blocking part of the water flow opening and closing mechanism 22 can block the through hole. The upper mounting seat 212 and lower mounting seat 213 are respectively provided on the upper and lower sides of the outer wall of the pipe body 211 for fixing the pipes to the external water pipes, ensuring the stability of the connection. The flow of water is controlled by blocking or opening the through hole through the blocking part of the water flow opening and closing mechanism 22. Specifically, when it is necessary to block the water flow, the blocking part of the water flow opening and closing mechanism 22 will move to the through hole position to block the through hole and prevent the water flow from passing through; when it is necessary for the water flow to pass through, the blocking part will move away from the through hole to allow the water flow to pass through smoothly.

[0027] In this process, the pipe body 211 serves as the basic structure of the entire valve body 21, providing a platform for the installation and support of other components. The through hole is the channel for water flow, and its design and size directly affect the flow rate and velocity. The mounting base is used to fix the valve body 21 to the external water pipe, ensuring the stability and sealing of the entire system and preventing water leakage. The water flow opening and closing mechanism 22 is the core component of the valve body 21. The movement of its blocking part realizes the control of water flow. Through precise mechanical design and operation, it ensures that the water flow can be opened and closed as needed.

[0028] Furthermore, in order to control the flow rate of high-speed water through the butterfly valve 2, the water flow opening and closing mechanism 22 includes: a rotating shaft 221 and a baffle 222. The rotating shaft 221 is vertically located at the center of the through hole. The upper end of the rotating shaft 221 passes through the mounting seat 212 on the pipe body 211 and is movably connected to the rotation limiting mechanism 232. The two ends of the rotating shaft 221 are symmetrically provided with baffles 222. The baffles 222 have a semi-circular structure, and the outer arc of the baffle 222 corresponds to the inner wall of the through hole.

[0029] In this embodiment, the water flow opening and closing mechanism 22 controls the flow of water by rotating the shaft 221 to move the baffle 222. The shaft 221 is vertically located at the center of the through hole and serves as the core transmission component. Its upper end is movably connected to the rotation limiting mechanism 232 to ensure precise control of the rotation angle. The rotation of the shaft 221 transmits external operating force to the baffle 222 through mechanical transmission, causing the baffle 222 to move within the through hole. The baffle 222 has a semi-circular structure, with both ends symmetrically arranged on the shaft 221, and its outer curvature matches the inner wall of the through hole. When the shaft 221 rotates, the baffle 222 moves accordingly, and its semi-circular structure can tightly fit against the inner wall of the through hole, thereby completely blocking the through hole and preventing water flow. Conversely, when the shaft 221 rotates in the opposite direction, the baffle 222 moves away from the through hole, allowing water to flow smoothly.

[0030] In this process, the rotating shaft 221 plays a crucial role in transmitting power and controlling position, ensuring that the baffle 222 can accurately seal or open the through hole. The design of the baffle 222 ensures a tight fit with the inner wall of the through hole, providing good sealing and preventing water leakage. The rotation limiting mechanism 232 restricts the rotation angle of the rotating shaft 221, ensuring that the baffle 222 completes the sealing or opening action in the correct position, thereby achieving precise control of the water flow.

[0031] Furthermore, the inner wall of the tube body 211 has two inwardly protruding sealing walls 214, which are located on both sides of the rotating shaft 221. There is a gap between the two sealing walls 214 for the rotating shaft 221 to pass through. The sealing walls 214 cooperate with the baffle 222 to block the through hole.

[0032] The two sealing walls 214 are located on both sides of the rotating shaft 221, providing a sealing mating surface for the baffle 222. A gap is left between the two sealing walls 214 for the rotating shaft 221 to pass through, ensuring that the rotating shaft 221 can rotate freely without interfering with the sealing walls 214.

[0033] Furthermore, the rotation limiting mechanism 232 includes: a support ring 41, a limiting seat 42, a lower pressure block 43, and a spring 44. The support ring 41 is installed on the top surface of the upper mounting base 212 and surrounds the rotating shaft 221. The upper end of the shaft is surrounded by positioning teeth 45. One end of the lower pressure block 43 is a limiting end, and the limiting end is provided with a toothed ring 46. The toothed ring 46 meshes with the positioning teeth 45. The support ring 41 and the limiting end are connected by the spring 44, which can support the toothed ring. 46 is engaged with positioning tooth 45, and the other end of the lower pressure block 43 is the lower pressure end 47; the limiting seat 42 includes: support cylinder 421 and limiting shell 422. The support cylinder 421 is installed on the top surface of the upper mounting seat 212 and surrounds the support ring 41. The upper end of the support cylinder 421 is connected to the limiting shell 422. The limiting shell 422 surrounds the lower pressure block 43. The limiting shell 422 and the support cylinder 421 have a guide groove 423 on one side for the lower pressure end 47 to move vertically.

[0034] During this process, the rotation limiting mechanism 232 achieves precise control of the rotation angle of the rotating shaft 221 through the coordinated action of the support ring 41, the limiting seat 42, the lower pressure block 43, and the spring 44. The support ring 41 is installed on the top surface of the upper mounting base 212 to provide support for the mechanism and surrounds the outer wall of the rotating shaft 221. The positioning tooth 45 at the upper end of the rotating shaft 221 meshes with the toothed ring 46 in the limiting end of the lower pressure block 43. The spring 44 connects the support ring 41 and the limiting end, providing elasticity to maintain the tight contact between the toothed ring 46 and the positioning tooth 45. The support cylinder 421 and the limiting shell 422 of the limiting seat 42 surround the lower pressure block 43 to ensure the stability of its vertical movement. When the angle needs to be adjusted, the lower pressure end 47 of the lower pressure block 43 is manually pressed down, the spring 44 is compressed, the toothed ring 46 disengages from the positioning tooth 45, and the rotating shaft 221 can rotate freely; after being released, the spring 44 returns to its original position, the toothed ring 46 re-engages, and the rotating shaft 221 is fixed in the new position. The entire mechanism ensures the accuracy and stability of the rotation angle of the rotating shaft 221 through a combination of mechanical limiting and elastic reset.

[0035] Furthermore, the rotating part 231 includes a rotating handle 51 and a connecting arm 52. The lower end of the connecting arm 52 is connected to the upper end face of the rotating shaft 221. The connecting arm 52 and the rotating shaft 221 cannot rotate relative to each other. The upper end of the connecting arm 52 passes through the limiting shell 422 and is radially fixedly connected to the rotating handle 51. The rotating handle 51 is used to control the rotation of the rotating shaft 221. The upper end of the connecting arm 52 passes through the limiting shell 422 and is radially fixedly connected to the rotating handle 51. The rotating handle 51 serves as an operating component for manually controlling the rotation of the rotating shaft 221. The torque applied by the rotating handle 51 is transmitted to the rotating shaft 221 through the connecting arm 52, thereby achieving precise control of the rotating shaft 221. This design ensures that the rotation angle of the rotating shaft 221 can be adjusted manually, while the rigid connection between the connecting arm 52 and the rotating shaft 221 ensures the efficiency of force transmission and the stability of the structure.

[0036] During this process, the rotating part 231 achieves precise manual control of the rotating shaft 221 through the coordinated action of the rotating handle 51 and the connecting arm 52. The lower end of the connecting arm 52 is rigidly connected to the upper end face of the rotating shaft 221, ensuring that the two cannot rotate relative to each other, thereby efficiently transmitting the torque applied by the rotating handle 51 to the rotating shaft 221. The upper end of the connecting arm 52 passes through the limiting shell 422 and is radially fixedly connected to the rotating handle 51. The rotating handle 51 serves as an operating component, facilitating manual control of the rotation angle of the rotating shaft 221. The limiting shell 422 provides guidance and support for the connecting arm 52, ensuring the stability of the rotation process. This design not only enables manual adjustment of the rotation angle of the rotating shaft 221 but also ensures efficient force transmission and structural reliability through the rigid connection between the connecting arm 52 and the rotating shaft 221.

[0037] Furthermore, one side of the through hole is the water inlet end, and the other side of the through hole is the water outlet end. A first sealing block 61 is provided at the end of one sealing wall 214 near the water inlet end, and a second sealing block 62 is provided at the end of the other sealing wall 214 near the water outlet end. Both the first sealing block 61 and the second sealing block 62 can fit against the surface of the rotating shaft 221.

[0038] Both the first sealing block 61 and the second sealing block 62 can fit tightly against the surface of the rotating shaft 221, forming a sealing barrier. When the rotating shaft 221 rotates, causing the baffle 222 to move to the through hole position, the baffle 222 cooperates with the sealing wall 214 to block the through hole. At the same time, the first sealing block 61 and the second sealing block 62 fit against the surface of the rotating shaft 221, preventing water leakage from the inlet and outlet ends. This design ensures the accuracy and reliability of water flow control while enhancing the sealing effect.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
