Description

Technical Field

[0001] This utility model relates to the field of valve-related technology, specifically to a piston-type flow regulating valve. Background Technology

[0002] Flow regulating and pressure regulating valves are the preferred valves for achieving flow and pressure control. As a mature product, they are widely used in large and medium-sized cities across the country, with over 10 years of market experience and widespread acclaim. In the future, with the expansion of urban water supply areas, higher engineering requirements, and increased automation, flow regulating and pressure regulating valves will undoubtedly have even broader development prospects. Flow regulating and pressure regulating valves, also known as piston-type multi-functional control valves, have multiple control functions (such as water level control, pressure reduction control, pressure holding and relief control, and flow control). They provide cavitation-free, turbulence-free, vibration-free, and sediment-resistant performance, making them widely used in large-scale water supply projects today.

[0003] Currently available flow control valves have complex structures, making them inconvenient for flow control operations and thus reducing the overall practicality of the device. Therefore, based on the above problems, this invention provides a piston-type flow control valve. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A piston-type flow regulating valve includes a valve body, a first connecting pipe fixedly connected to one side of the valve body, a second connecting pipe fixedly connected to the other side of the valve body, and a cooperating flow regulating mechanism provided between the valve body and the first connecting pipe.

[0007] Furthermore, the flow adjustment mechanism includes a fixed ring, which is fixedly disposed inside the first connecting pipe. An adjusting cylinder is slidably disposed inside the fixed ring. Several rectangular flow adjustment slots are evenly distributed through the adjusting cylinder. A connecting plate is slidably disposed inside each rectangular flow adjustment slot. Each connecting plate is fixedly connected to the inner wall of the fixed ring.

[0008] A piston head is fixedly connected to one side of the regulating cylinder. The piston head is located inside the first connecting pipe and slides along the inner wall of the first connecting pipe. A fixing block is fixedly connected to the other side of the regulating cylinder. An adjusting component is provided between the fixing block and the valve body.

[0009] Furthermore, the adjusting assembly includes two fixing plates, each of which is fixedly connected to the outer wall of the valve body, and a worm gear is rotatably provided between the two fixing plates, with a worm wheel meshing on one side of the worm gear;

[0010] Both the front and rear sides of the valve body are fixed with mating blocks. The valve body is provided with a mating plate. A rotating rod is fixedly installed through the mating plate. Both ends of the rotating rod pass through the valve body and the corresponding mating block in sequence and are rotatably connected to the valve body and the corresponding mating block. The front end of the rotating rod extends through to the outside of the mating block located in front and is fixedly connected to the worm gear. A double connecting plate is movably hinged between the mating plate and the fixed block.

[0011] Furthermore, the top end of the worm gear extends through to the outside of the fixed plate located above and is fixed with an adjusting head.

[0012] Furthermore, flange rings are fixedly provided at the opposite ends of the first connecting pipe and the second connecting pipe, and an annular groove is provided on each flange ring, with a sealing ring provided in each annular groove.

[0025] Example 1

[0026] To address the technical problems in the background section, the following piston-type flow regulating valve is provided:

[0027] Combination Figure 1-5 As shown, the present invention provides a piston-type flow regulating valve, including a valve body 1, a first connecting pipe 2 connected and fixed on one side of the valve body 1, a second connecting pipe 3 connected and fixed on the other side of the valve body 1, and a cooperating flow regulating mechanism 6 provided between the valve body 1 and the first connecting pipe 2.

[0028] The flow adjustment mechanism 6 includes a fixed ring 61, which is fixedly installed inside the first connecting pipe 2. An adjusting cylinder 62 is slidably installed inside the fixed ring 61. Several rectangular flow adjustment grooves 622 are evenly opened through the adjusting cylinder 62. A connecting plate 611 is slidably installed inside each rectangular flow adjustment groove 622. Each connecting plate 611 is fixedly connected to the inner wall of the fixed ring 61.

[0029] A piston head 621 is fixedly connected to one side of the regulating cylinder 62. The piston head 621 is located inside the first connecting pipe 2 and slides along the inner wall of the first connecting pipe 2. A fixing block 623 is fixedly connected to the other side of the regulating cylinder 62. An adjusting component is provided between the fixing block 623 and the valve body 1.

[0030] The adjusting assembly includes two fixed plates 66, each fixed plate 66 is fixedly connected to the outer wall of the valve body 1, and a worm gear 67 is rotatably provided between the two fixed plates 66, and a worm wheel 68 is meshed on one side of the worm gear 67.

[0031] Both the front and rear sides of the valve body 1 are fixed with mating blocks 7. A mating plate 64 is provided inside the valve body 1. A rotating rod 63 is fixedly installed through the mating plate 64. Both ends of the rotating rod 63 pass through the valve body 1 and the corresponding mating block 7 in sequence and are rotatably connected to the valve body 1 and the corresponding mating block 7. The front end of the rotating rod 63 extends through to the outside of the mating block 7 located in front and is fixedly connected to the worm gear 68. A double connecting plate 65 is movably hinged between the mating plate 64 and the fixed block 623.

[0032] The top of the worm gear 67 extends through to the outside of the fixed plate 66 located above and is fixed with an adjusting head.

[0033] For specific usage, please refer to Figure 3 The water flows from right to left. When the flow channel is blocked, several connecting plates 611 contact the rightmost inner wall of the corresponding rectangular flow regulating channel 622. When the valve is adjusted as needed, rotating the adjusting head drives the worm gear 67 to rotate along the two fixed plates 66. Simultaneously, under meshing operation, the worm wheel 68 rotates, which in turn drives the rotating rod 63 to rotate, thereby causing the mating plate 64 to rotate within a certain range. At the same time, under hinge operation, the two ends of the double connecting plate 65 are movably hinged along the fixed block 623 and the mating plate 64, respectively, thereby causing the adjusting cylinder 62 to slide to the right along the fixed ring 61. This causes each rectangular flow regulating channel 622 to slide along the corresponding connecting plate 611, while simultaneously driving the piston. The head 621 slides to the right along the inner wall of the first connecting pipe 2. As the regulating cylinder 62 moves to the right, the distance of the rectangular flow regulating groove 622 discharge channel increases, and the water flow into the first connecting pipe 2 increases. This allows for effective flow regulation of the valve body 1 according to usage requirements. The structure is not only ingenious and compact but also easy to operate and promote. Furthermore, the regulating cylinder 62 is equipped with several rectangular flow regulating grooves 622 arranged in a circular array. The regulating cylinder 62 is evenly divided into multiple rectangular flow regulating grooves 622 (referred to as multiple small flow channels). These multiple small flow channels form jet collisions towards the center of the pipeline, which can achieve pressure reduction and effectively reduce the impact force on the regulating cylinder 62 and the first connecting pipe 2, thus increasing the service life of the overall valve.

[0034] Example 2

[0035] like Figure 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0036] Both the first connecting pipe 2 and the second connecting pipe 3 have flange rings 4 fixedly installed at opposite ends. Each flange ring 4 has an annular groove, and a sealing ring 5 is installed in each annular groove. Several mounting holes are evenly distributed through the flange ring 4.

[0037] In practical use, based on Embodiment 1, if it is necessary to further enhance the practicality of the overall device, the operation is as follows:

[0038] By providing an annular groove on the flange ring 4 and a sealing ring 5 inside the annular groove, the sealing performance of the entire device is increased when the flange ring 4 is connected to the flange ring on the external pipeline, thereby improving the practicality of the entire device.
