Description
Technical Field
[0001] This utility model relates to the field of butterfly valve technology, specifically a dual-channel single-handle regulating butterfly valve. Background Technology
[0002] The main function of a butterfly valve is to control and regulate the flow of fluid in a pipeline. It can effectively cut off the flow of the medium. The single-handle regulating butterfly valve realizes the opening and closing control and flow regulation of the fluid by rotating a disc-shaped butterfly plate. It has the characteristics of compact structure and flexible operation.
[0003] Chinese patent CN209540099U discloses a dual-channel single-handle adjustable butterfly valve, comprising a valve body with a main channel connected to a first branch channel and a second branch channel. A first valve plate matching the first branch channel is rotatably connected to the main channel, and a second valve plate matching the second branch channel is fixedly connected to the side wall of the first valve plate. The first and second valve plates are vertically arranged. A vertically arranged valve handle is fixedly connected to the upper side wall of the first valve plate, and the valve handle penetrates the valve body and extends to the outside of the valve body and is rotatably connected to the valve body. A rotating rod is fixedly connected to one end of the valve handle outside the valve body. The valve handle is simple to operate and convenient to use. Under the elastic force of the spring, the locking block is engaged in the locking groove to fix the valve handle, preventing the valve handle from loosening and causing the first or second branch channel to be poorly sealed. The valve handle is easy to rotate or fix, improving work efficiency.
[0004] The valve handle of the butterfly valve described above is prone to rotation under external impact, which in turn changes the liquid flow rate inside the regulating butterfly valve. The unstable liquid flow rate will affect the subsequent use of the liquid. In addition, the valve handle surface in the above solution does not have a flow regulation control structure, which may cause the internal flow rate of the regulating butterfly valve to deviate from the required liquid flow rate. Utility Model Content
[0005] The purpose of this utility model is to provide a dual-channel single-handle regulating butterfly valve to solve the problem mentioned in the background art that the valve handle of the butterfly valve is easily rotated under external force impact, which leads to changes in the internal liquid flow rate of the regulating butterfly valve, resulting in unstable liquid flow rate. Furthermore, the lack of a flow regulation control structure on the valve handle surface may cause the internal flow rate of the regulating butterfly valve to deviate from the required liquid flow rate.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-channel single-handle adjustable butterfly valve, comprising an adjustable butterfly valve body, a control structure fixedly installed on the top of the adjustable butterfly valve body, an adjusting handle being drivenly connected to one side of the control structure, mounting plates being symmetrically fixedly installed on one side of the control structure, a threaded rod being fixedly installed between the two mounting plates, an adjusting block being slidably connected to the outer end of the threaded rod, positioning nuts being symmetrically fixedly installed on both sides of the adjusting block, an L-shaped plate being fixedly installed on one side of the adjusting block, an adjusting ring being fixedly installed on one side of the L-shaped plate, and multiple pressing plates being fixedly installed on one side of the adjusting ring;
[0007] The adjusting handle has multiple evenly spaced scale grooves on one side, and a pointer is movably connected to one side of each scale groove. The pointer is fixedly connected to the adjusting ring.
[0008] Preferably, connecting rings are symmetrically fixedly installed on both sides of the regulating butterfly valve body, and replacement components are provided inside both connecting rings. A fixing plate is movably connected to one side of one of the connecting rings. Fixing bolts are connected through the fixing plate and the inner wall of one of the connecting rings. A double-channel pipe is fixedly installed on one side of the fixing plate, and a connector is fixedly installed on one side of the double-channel pipe.
[0009] Preferably, the replacement component includes a mounting ring, which is fixedly installed inside another connecting ring. The mounting ring has a mounting groove inside, and a magnetic suction element is fixedly installed inside the mounting groove.
[0010] Preferably, an iron sheet is movably connected to one side of the magnetic suction component, and a circular filter frame is fixedly installed on one side of the iron sheet. The circular filter frame is movably connected to the outer side of the mounting ring.
[0011] Preferably, the positioning nut passes through the threaded rod and is threaded to the outer end, the adjusting ring is sleeved on the outer end of the adjusting handle, and the scale grooves are evenly distributed on the surface of the adjusting handle.
[0012] Preferably, the fixing plate and one of the connecting rings are connected by fixing bolts and nuts. Eight fixing bolts are evenly arranged. The magnetic poles of the magnetic attracting element and the iron sheet are opposite and have mutual attraction.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By setting an adjustment handle, scale groove and pointer, rotating the adjustment handle can drive the scale groove to rotate, and the pointer makes it easy for the staff to see the scale on the scale groove. By controlling the scale of the adjustment handle rotation, the staff can accurately control the flow speed of the liquid in the body of the regulating butterfly valve, reduce the error of the liquid transmission speed, and thus improve the accuracy of the use of the dual-channel single-handle regulating butterfly valve.
[0015] 2. By incorporating a threaded rod, adjusting block, positioning nut, L-shaped plate, adjusting ring, and pressing plate, the adjusting block can slide at the outer end of the threaded rod. Two positioning nuts can limit and fix the adjusting block. The adjusting block drives the L-shaped plate for adjustment, which in turn drives the adjusting ring. The adjusting ring then drives the pressing plate. When the pressing plate is adjusted to the surface of the adjusting handle, the adjusting handle can be pressed against its surface, thus limiting and fixing the adjusting handle and preventing it from rotating due to external influences. This avoids altering the internal flow velocity of the dual-channel single-handle regulating butterfly valve, resulting in more precise control of the internal flow velocity.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: a dual-channel single-handle adjustable butterfly valve, including an adjustable butterfly valve body 1. A control structure 2 is fixedly installed on the top of the adjustable butterfly valve body 1. An adjusting handle 3 is drivenly connected to one side of the control structure 2. The adjusting handle 3 can adjust the position of the valve core inside the adjustable butterfly valve body 1, thereby controlling the flow of liquid inside the adjustable butterfly valve body 1. Mounting plates 41 are symmetrically fixedly installed on one side of the control structure 2. A threaded rod 42 is fixedly installed between the two mounting plates 41. An adjusting block 43 is slidably connected to the outer end of the threaded rod 42. Positioning nuts 44 are symmetrically fixedly installed on both sides of the adjusting block 43. The two positioning nuts 44 can limit the two sides of the adjusting block 43, thereby fixing the adjusting block 43. An L-shaped plate 45 is fixedly installed on one side of the adjusting block 43. An adjusting ring 46 is fixedly installed, and multiple pressing plates 47 are fixedly installed on one side of the adjusting ring 46. Multiple scale grooves 48 are evenly distributed on one side of the adjusting handle 3. A pointer 49 is movably connected to one side of the scale grooves 48. The pointer 49 is fixedly connected to the adjusting ring 46. The positioning nut 44 passes through the threaded rod 42 and is threaded to the outer end. The adjusting ring 46 is sleeved on the outer end of the adjusting handle 3. The scale grooves 48 are evenly distributed on the surface of the adjusting handle 3. The pointer 49 can observe the angle of rotation of the adjusting handle 3, and thus control the speed of liquid flow inside the adjusting butterfly valve body 1. After adjustment, the adjusting block 43 slides on the outer end of the threaded rod 42. The adjusting block 43 drives the L-shaped plate 4, the adjusting ring 46 and the pressing plates 47 in sequence for adjustment. The pressing plates 47 fix the adjusting handle 3 to prevent the adjusting handle 3 from being rotated by external collisions.
[0023] Please see Figure 1 , Figure 2 and Figure 3The regulating butterfly valve body 1 has symmetrically fixed connecting rings 5 on both sides. Each connecting ring 5 has a replacement component 6 inside. A fixing plate 7 is movably connected to one side of one of the connecting rings 5. Fixing bolts 8 penetrate the inner wall of both the fixing plate 7 and one of the connecting rings 5. A dual-channel pipe 9 is fixedly installed on one side of the fixing plate 7. This device has two dual-channel pipes 9, which can split the liquid flow. A connector 10 is fixedly installed on one side of each dual-channel pipe 9. The replacement component 6 includes a mounting ring 61, which is fixedly installed inside the other connecting ring 5. A mounting groove 62 is opened inside the mounting ring 61, and a magnetic suction component 63 is fixedly installed inside the mounting groove 62. One side of the magnetic suction component 63 is movably connected to... The iron plate 64 filters impurities inside the liquid, preventing them from entering the regulating butterfly valve body 1 and causing blockage, thus extending the service life of the regulating butterfly valve body 1. A circular filter frame 65 is fixedly installed on one side of the iron plate 64. The circular filter frame 65 can be movably connected to the outer side of the mounting ring 61. The fixing plate 7 and one of the connecting rings 5 are connected by fixing bolts 8 and nuts. Eight fixing bolts 8 are evenly arranged. The magnetic attraction member 63 and the iron plate 64 have opposite magnetic poles and attract each other. The iron plate 64 on one side of the circular filter frame 65 is inserted into the mounting groove 62, and the circular filter frame 65 is fixedly connected by the attraction between the magnetic attraction member 63 and the iron plate 64.
[0024] Working principle: Connect the water pipe to the dual-channel pipe 9 using connector 10. The operator rotates the adjusting handle 3, which drives the valve core to adjust. Simultaneously, the adjusting handle 3 drives the scale groove 48 to rotate. When the adjusting handle 3 is rotated to the required scale, the adjusting block 43 is pulled to slide on the outer end of the threaded rod 42. The adjusting block 43 drives the L-shaped plate 45 to adjust, the L-shaped plate 45 drives the adjusting ring 46 to adjust, and the adjusting ring 46 drives the pressing plate 47 to adjust. The pressing plate 47 presses and fixes the surface of the adjusting handle 3, thereby fixing the position of the valve core inside the adjusting butterfly valve body 1. The water flow first uses the circular filter frame 65 to filter impurities in the liquid, and then the water flows from the inside of the adjusting butterfly valve body 1 into the inside of the dual-channel pipe 9, where the water flow is separated and discharged. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
