Description

Technical Field

[0001] The present application relates to the technical field of flow control valves, and in particular to a pipeline-based axial flow control valve. Background Art

[0002] Axial flow flow control valve (axial flow valve for short) is a valve that achieves flow regulation through the coaxial flow of the valve core and the medium. It is widely used in natural gas transportation, water conservancy and hydropower, petrochemical industry and municipal engineering. For example, the patent with publication number CN220749066U specifically discloses a medium-flow stable axial flow valve. The axial flow valve rotates a rotating rod, and the rotation of the rotating rod simultaneously drives the rotation of the bevel gear 2, which is then driven by the meshing transmission between the bevel gear 2 and the bevel gear 1, thereby driving the internal threaded pipe fitting to rotate. Due to the plug-in fit between the limit column and the slot, the rotation of the valve disc is restricted. Then, the threaded fit between the internal threaded pipe fitting and the screw rod can drive the valve disc to move, thereby achieving the purpose of controlling the opening and closing of the valve disc. When axial flow valves are used in water conservancy, hydropower, or municipal engineering, most of the fluid passing through the valve body is water. Consequently, when faced with extreme environments, such as when the ambient temperature drops below 0°C, the water in the valve body may begin to freeze. This is especially true in northern cold regions where winter temperatures often drop below zero, significantly increasing the risk of valve body freezing. Furthermore, since the valve body is often located at the end or turning point of a pipeline, water flow is prone to stagnation, making it more susceptible to freezing. However, although the above patent can achieve flow control, it does not have a means to remove ice from the valve body after ice forms inside. As a result, in extreme environments, the water flow inside the valve body is easily frozen, thereby affecting the normal operation of the valve body. Therefore, it is necessary to provide an axial flow control valve based on a pipeline to solve the above problems.

DETAILED DESCRIPTION

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0020] Example 1: Figure 1-Figure 3 As shown, the present application provides an axial flow control valve based on a pipeline, comprising a housing 1, a flow control component 2 is provided inside the housing 1, and the flow control component 2 is used to control the flow of a fluid, specifically: The flow control assembly 2 includes a valve body 25 fixedly mounted inside the housing 1. The valve body 25 has a cavity extending therethrough to facilitate the passage of fluid. Pipe sections are provided at both ends of the housing 1. Both sets of pipe sections are provided with flanges to facilitate connection to other pipes. It should be noted that the pipe sections communicate with the cavity of the valve body 25, and the diameter of the pipe sections is smaller than the diameter of the cavity inside the valve body 25, thereby forming a step between the two. The housing 1 is provided with an upper flange portion 21, and a support frame 221 is fixedly mounted on the upper flange portion 21. A control unit 22 is provided on the top of the support frame 221. A motor (not shown in the figure) is provided inside the control unit 22. A rotating shaft 34 is fixedly mounted on the output end of the motor. One end of the rotating shaft 34 passes through the support frame 221, the upper flange portion 21, the housing 1 and the valve body 25, and extends into the interior of the valve body 25. Continue to refer Figure 3 A connecting column 33 is provided inside the valve body 25, a housing 27 is fixedly mounted on the bottom of the connecting column 33, a lower end of the rotating shaft 34 is located inside the housing 27, an accommodating cavity is provided inside the housing 27, and a second gear 35 is fixedly mounted on the bottom end of the rotating shaft 34; A screw rod 28 is mounted on a bearing inside the housing 27, and a fixed plate 3 is provided inside the housing 27. The screw rod 28 is rotatably mounted on the fixed plate 3. A first gear 29 is fixedly mounted on the screw rod 28. The first gear 29 is meshed with a second gear 35. Driven by the motor, the first gear 29 drives the rotating shaft 34 to rotate, thereby driving the second gear 35 to rotate, and driving the first gear 29 to rotate, thereby driving the screw rod 28 to rotate; A piston 32 adapted to the pipe portion is slidably provided at one end of the housing 27 to seal the pipe portion of the housing 1. A groove 421 is provided inside the piston 32, and two sets of guide rods 31 are fixedly mounted on the inner wall of the groove 421. One end of the guide rod 31 slides through the fixed plate 3. A sliding sleeve 36 is mounted on the inner wall of the groove 421. The sliding sleeve 36 is threadedly mounted on the screw rod 28. When the screw rod 28 rotates, the sleeve 36 is driven to move along the axis of the screw rod 28. The movement direction of the sleeve 36 is restricted by the guide rod 31, thereby driving the piston 32 to move inside the cavity of the valve body 25 and approach or move away from the pipeline portion to control the opening and closing of the pipeline portion of the housing 1. The distance between the piston 32 and the pipeline portion can also be controlled to change the speed at which water flows into the pipeline portion of the valve body 25, thereby controlling the water flow in the pipeline portion. It should be noted that if Figure 9As shown, a partition plate 423 is provided on the end surface of the housing 27. A sealing ring (not shown) is provided on the partition plate 423. The same sealing ring is provided on the piston 32 to seal the sliding portion between the piston 32 and the housing 27 when the piston 32 moves. A through groove 422 is provided through the partition plate 423, and the sliding sleeve 36 passes through the through groove 422. At the same time, the two sets of guide rods 31 slide through the partition plate 423 to avoid mechanical interference. Because the valve body 25 is mostly located at the end or turning point of the pipeline, the water flow is easy to stagnate and even more likely to freeze. In order to prevent the interior of the valve body 25 from freezing in cold weather, a gap 24 is provided between the valve body 25 and the shell 1. At the same time, a liquid inlet pipe 23 is provided at one end of the shell 1, and a liquid outlet pipe 26 is provided at the other end of the shell 1. One end of the liquid inlet pipe 23 and the liquid outlet pipe 26 are both inserted into the gap 24. When the interior of the valve body 25 freezes, liquid with a certain amount of heat is introduced into the gap 24 through the liquid inlet pipe 23 and discharged from the liquid outlet pipe 26, thereby heating the valve body 25 and melting the ice inside the valve body 25. It should be noted that the temperature of the liquid with heat needs to be gradually increased to avoid the valve body 25 from bursting due to excessive temperature. In order to accelerate the melting speed of ice cubes in the valve body 25, Figure 2-Figure 4 As shown, a de-icing assembly 4 is provided on the piston 32, and the de-icing assembly 4 is used to knock out ice cubes when ice forms inside the valve body 25; The de-icing assembly 4 includes an air pipe 41 disposed within the upper flange portion 21. One end of the air pipe 41 extends out of the upper flange portion 21. The end extending out of the upper flange portion 21 can be connected to an external pulse device and an air extraction device (not shown) via a shunt pipe. The other end of the air pipe 41 extends into the interior of the housing 27. The piston 32 is provided with a plurality of slideways 431 , wherein a tapered plug 43 is slidably disposed within the slideways 431 . One end of the tapered plug 43 has a spike 46 , and the other end of the tapered plug 43 extends into the interior of the groove 421 . A protrusion (not shown) is fixedly disposed at the end of the tapered plug 43 extending into the groove 421 . A first spring 47 is disposed between the inner wall of the groove 421 and the protrusion, and is sleeved on the end of the tapered plug 43 extending into the groove 421 . Continue to refer Figure 3-Figure 4 A disc 42 is slidably provided on the sliding sleeve 36 to prevent the sliding sleeve 36 from driving the disc 42 to move when the sliding sleeve 36 moves axially. The disc 42 is located on one side of the partition 423, and an elastic member (not shown in the figure) is connected between the disc 42 and the partition 423. A plurality of push rods 48 are provided on the disc 42, and a blind hole (not shown in the figure) is opened inside the conical plug 43. The push rods 48 are slidably provided inside the blind hole of the conical plug 43. Driven by the pulse device, pulse gas is introduced into the interior of the housing 27. The pulse gas passes through the through slot 422 and pushes the disc 42 to move on the sliding sleeve 36, thereby driving the multiple groups of push rods 48 to move inside the conical plug 43 until the push rods 48 abut against the inner wall of the blind hole inside the conical plug 43, thereby pushing the conical plug 43 to move, so as to synchronously impact the ice, thereby forming a "resonance crushing effect", enhancing the coupling of impact energy to the ice layer, improving the crushing efficiency, and thus breaking the ice, thereby cooperating with the heating measures to accelerate the melting of the ice; It should be noted that the slideway 431 has a tapered groove 44. Figure 4 In the middle, the tapered plug 43 is narrow on the left and wide on the right, and has a tapered portion 45 adapted to the tapered groove 44. Therefore, in the initial state, due to the action of the first spring 47, the tapered portion 45 fits with the tapered groove 44, thereby achieving sealing. At the same time, when water flows through the valve body 25, the tapered plug 43 is pressed into the tapered groove 44 under the action of the water pressure, further enhancing the sealing effect. A circular groove is provided at one end of the tapered groove 44 near the groove 421, and the circular groove is connected to the groove 421 to facilitate the sliding of the tapered plug 43. In summary, when in use, the pipe portion is connected to the external pipe via the flange, and the control portion 22 drives the rotating shaft 34 to rotate, thereby driving the screw rod 28 to rotate through the cooperation of the first gear 29 and the second gear 35, driving the sliding sleeve 36 to move along the axis of the screw rod 28, and limiting the movement direction of the sliding sleeve 36 under the restriction of the guide rod 31, thereby driving the piston 32 to move closer to or away from the pipe portion inside the valve body 25, thereby controlling the water flow that can enter the gap 24 of the pipe portion of the valve body 25, thereby controlling the water flow rate; When ice forms inside the valve body 25 , the liquid inlet pipe 23 and the liquid outlet pipe 26 are connected to an external heating circulation device. Driven by the heating circulation device, liquid with heat is introduced into the gap 24 and discharged from the liquid outlet pipe 26 to heat the valve body 25 (liquid can also be added manually) to melt the ice inside the valve body 25 . At the same time, the pulse device is started to pass pulse gas into the shell 27 , and then the conical plug 43 is pushed out of the piston 32 synchronously through the disc 42 and the push rod 48 , driving the spike 46 to impact the ice synchronously. Then the air extraction device extracts the gas, and the conical plug 43 is reset under the action of the restoring force of the first spring 47 , thereby driving the conical plug 43 to reset. The disc 42 is reset under the action of the restoring force of the elastic member. This reciprocating process can repeatedly impact and break the ice inside the valve body 25 , thereby accelerating the melting speed of the ice inside the valve body 25 .

[0021] Example 2: Although the above process can achieve ice crushing, the cost is relatively increased due to the addition of pulse equipment and air extraction equipment. In the case of thin ice or small valves, manual driving is more convenient to crush ice. To solve this problem, Figure 5-Figure 9 As shown, a driving assembly 5 is provided on the flow control assembly 2, and the driving assembly 5 is used to manually control the extension of the tapered plug 43; The driving assembly 5 includes a rotating rod 52 rotatably mounted on the support frame 221, a rotating disk 51 being fixedly mounted on one end of the rotating rod 52, a first bevel gear 53 being fixedly mounted on the other end of the rotating rod 52, and a rotating drum 55 being rotatably mounted on the rotating shaft 34, a second bevel gear 54 being fixedly mounted on the upper end of the rotating drum 55, the second bevel gear 54 being meshed with the first bevel gear 53, and the rotating disk 51 can be manually rotated to drive the rotating rod 52 to rotate, thereby driving the rotating drum 55 to rotate through the first bevel gear 53 and the second bevel gear 54; Continue to refer Figure 9 The lower end of the rotating drum 55 extends into the interior of the housing 27. A notched gear 56 is fixedly installed at the lower end of the rotating drum 55. At the same time, a mounting box 58 is fixedly installed on the inner wall of the groove 421. A rack 57 is slidably provided inside the mounting box 58. A round rod is fixedly installed on the rack 57. The rack 57 is meshed with the notched gear 56. A connecting plate 510 is fixedly mounted on one end of the round rod. Part of the connecting plate 510 is slidably disposed inside the mounting box 58. A second spring 59 is disposed between the connecting plate 510 and the mounting box 58. A pushing block 511 is fixedly mounted on the end of the connecting plate 510 away from the mounting box 58. The pushing block 511 is in contact with one side of the disc 42. It should be noted that the notched gear 56 has a notch, and the elastic force of the second spring 59 is greater than the elastic force of the first spring 47. At the same time, in the initial state, the pushing block 511 is in contact with the disc 42. In summary, when facing thin ice or small pipes, the rotating disk 51 is rotated to drive the rotating rod 52 to rotate, thereby driving the rotating drum 55 to rotate through the first bevel gear 53 and the second bevel gear 54, and synchronously driving the notched gear 56 to rotate, and then driving the round rod to slide on the mounting box 58 through the rack 57, and driving the pushing block 511 to move through the connecting plate 510, and then driving the multiple groups of tapered plugs 43 to push out the piston 32 through the disk 42 and the ejector rod 48 to impact the ice; When the notched gear 56 rotates to the notch, the rack 57 separates from the notched gear 56, and under the action of the restoring force of the second spring 59, the connecting plate 510 is driven to reset, thereby driving the rack 57 to reset, and synchronously driving the pushing block 511 to reset. The fixed plate 3 can block it to avoid affecting the second gear 35; At this time, the disc 42 is reset under the action of the elastic member, and as the turntable 51 continues to rotate, the notched gear 56 repeatedly engages and disengages with the rack 57, thereby driving the push block 511 to repeatedly hit the disc 42, thereby pushing the conical plug 43 to repeatedly hit the ice cubes. It should be noted that a socket can be opened on the support frame 221, and then the turntable 51 can be restricted by inserting a pin into the turntable 51 and inserting it into the socket.

Various modifications and variations are possible for those skilled in the art.
