Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a valve fluid channel flow regulating device. Background Technology

[0002] A valve is a device used to control the flow of fluid in a pipeline. Faucets, which are common in daily life, are also a type of valve. They are also widely used in industries, construction, and energy. The valve fluid passage is a part of the valve. The path through which the fluid flows within the valve is the valve fluid passage. In order to better regulate and control the flow rate within the valve fluid passage, a flow regulating device is usually installed in this part.

[0003] Flow regulating devices are generally located in the inlet section of the valve fluid passage. They control the flow rate by adjusting the size of the inlet. Because the flow rate needs to be adjusted frequently, the piston part moves constantly. The friction generated by this movement will wear down the piston part. If it is not replaced regularly, it will directly affect the sealing performance. In the current technology, the external appearance of the flow regulating device is an integrated design. If the piston part is not sealed well, the entire flow regulating device will be replaced. Although the cost of the flow regulating device is not high, it will cause material waste for the entire flow regulating device and is not conducive to environmental protection.

[0004] Therefore, how to provide a valve fluid channel flow regulation device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a valve fluid channel flow regulating device. This invention solves the problem that in the prior art, the outer shell of the flow regulating device is an integrated design, which means that when the piston wears and affects the seal, the entire flow regulating device needs to be replaced, resulting in material waste and environmental problems.

[0006] A valve fluid channel flow regulating device according to an embodiment of the present utility model includes a housing, an inlet pipe and an outlet pipe. The inlet pipe is disposed on the side of the housing, and the outlet pipe is disposed at one end of the housing. A piston is movably connected inside the housing near the outlet pipe. A docking assembly is disposed on the side of the piston away from the outlet pipe. A sealing disc is movably sleeved on the docking assembly. Both the sealing disc and the piston are movably attached to the inner wall of the housing. An adjusting rod is disposed at the end of the docking assembly away from the piston. The other end of the adjusting rod passes through the housing and extends to the outside of the housing.

[0007] The adjusting rod is movably fitted with a disassembly cover, which is threaded onto the end of the outer casing away from the outlet pipe.

[0008] The disassembly cover is provided with a positioning component. One end of the positioning component is attached to the surface of the adjusting rod. The positioning component includes a positioning block, a threaded through hole and a limiting bolt. The positioning block is fixed on the disassembly cover (29) near the adjusting rod. The threaded through hole is opened on the positioning block. The limiting bolt moves inside the threaded through hole. A flat cut surface is opened on the side of the adjusting rod corresponding to the position of the positioning block. One end of the limiting bolt moves on the flat cut surface.

[0009] An adjustment component for adjusting the adjustment rod is provided on the side of the positioning block away from the disassembly cover.

[0010] The adjustment assembly includes a positioning ring, a rotating ring, a connecting rod, a screw, and an internal threaded hole. The positioning ring is fixed on the positioning block, the rotating ring is rotatably connected to the inner wall of the positioning ring through a bearing, the connecting rod is fixed on the rotating ring, and the other end of the connecting rod is fixed to the screw. The internal threaded hole is opened on the end face of the adjustment rod located outside the housing, and the screw is threaded into the inside of the internal threaded hole.

[0011] The docking assembly includes a rotating rod, a docking sleeve, a docking screw hole, a threaded head, a docking through hole, and a pin. The rotating rod is rotatably connected to the side of the piston away from the outlet pipe. The docking sleeve is movably fitted onto the surface of the rotating rod. The sealing disc is movably fitted onto the docking sleeve. The docking screw hole is opened on the end face of the docking sleeve away from the rotating rod. The threaded head is fixed on the end face of the adjusting rod located inside the outer shell. The threaded head is threaded into the inside of the docking screw hole. The docking through hole is opened on the docking sleeve and the rotating rod, and the docking through hole connects the docking sleeve and the rotating rod. The pin is movably inserted into the inside of the docking through hole. One end of the pin passes through the docking through hole and extends to the other side of the docking sleeve.

[0012] The docking assembly also includes a limiting assembly, which includes a limiting groove, an elastic element, and a limiting head. The limiting groove is formed on the surface of the pin. The elastic element and the limiting head are both movable within the limiting groove. One end of the elastic element is movably connected to the inner wall of the limiting groove, and the other end of the elastic element is movably connected to the end face of the limiting head. The other end of the limiting head passes through the limiting groove and extends to the outside of the limiting groove. The limiting head is movable on the side of the docking sleeve.

[0013] Sealing rings are provided at the top and bottom of the sealing disc at the positions corresponding to the mating sleeve and the adjusting rod.

[0014] The distance between the sealing disc and the piston is matched with the diameter of the inlet pipe. When the piston completely seals the outlet pipe, the connection between the inlet pipe and the outer shell is between the sealing disc and the piston.

[0015] The beneficial effects of this utility model are:

[0016] By setting up a docking assembly, a sealing disc, and a disassembly cover, the disassembly cover can be rotated to separate from the outer casing. Then, by pulling the adjusting rod, the sealing disc, docking assembly, and piston can be separated from the outer casing, allowing the piston and sealing disc to be replaced. This solves the problem that in the existing technology, the outer casing of the flow regulating device is an integrated design, so when the piston wears and affects the seal, the entire flow regulating device has to be replaced, which wastes materials and is not conducive to environmental protection.

[0017] By setting up a docking assembly, the sealing disc and piston need to be replaced separately. By disassembling the docking assembly, the sealing disc and piston can be removed and replaced independently, thus eliminating the need to replace the piston and sealing disc as a whole.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1 , Figure 2 and Figure 3The system includes a housing 1, an inlet pipe 2, and an outlet pipe 3. The inlet pipe 2 is located on the side of the housing 1, and the outlet pipe 3 is located at one end of the housing 1. A piston 4 is movably connected inside the housing 1 near the outlet pipe 3. A docking assembly 5 is located on the side of the piston 4 away from the outlet pipe 3, mainly used to install the piston 4 and the sealing disc 6. The docking assembly 5 includes a rotating rod 18, a docking sleeve 19, a docking screw hole 20, a threaded head 21, a docking through hole 22, and a pin 23. The rotating rod 18 is rotatably connected to the side of the piston 4 away from the outlet pipe 3. Driven by the rotating rod 18, even if the piston 4 rotates, it will rotate around its own central axis. The docking sleeve 19 is movably fitted onto the surface of the rotating rod 18, and the docking screw hole 20 is opened on the end face of the docking sleeve 19 away from the rotating rod 18. The threaded head 21 is fixed to one end face of the adjusting rod 7 located inside the outer casing 1. The threaded head 21 is threaded into the inside of the mating screw hole 20. The mating through hole 22 is opened on the mating sleeve 19 and the rotating rod 18, and the mating through hole 22 connects the mating sleeve 19 and the rotating rod 18. The pin 23 is movably inserted into the inside of the mating through hole 22. One end of the pin 23 passes through the mating through hole 22 and extends to the other side of the mating sleeve 19. The mating assembly 5 also includes a limiting assembly 24, which includes a limiting groove 25, an elastic element 26, and a limiting head 27. The elastic element 26 is a spring, which pushes the limiting head 27 out. The limiting groove 25 is opened on the surface of the pin 23. Both the elastic element 26 and the limiting head 27 are movable in the limiting groove 25. One end of the elastic element 26... The elastic element 26 is movably connected to the inner wall of the limiting groove 25, and the other end of the elastic element 26 is movably connected to the end face of the limiting head 27. The other end of the limiting head 27 extends to the outside of the limiting groove 25 after passing through the limiting groove 25. The limiting head 27 moves on the side of the docking sleeve 19. One end of the pin 23 has a protrusion. After the pin 23 passes through the docking through hole 22, one end of the pin 23 is limited by the protrusion, and then the other end is limited by the limiting head 27. The limiting head 27 is pushed out of the limiting groove 25 by the elastic element 26. At this time, the limiting head 27 is higher than the docking through hole 22 and fits against the side of the docking sleeve 19 to limit the pin 23, ensuring the stability of the pin 23. During operation, after the disassembly cover 29 is separated from the outer shell 1, the adjusting rod 7, docking assembly 5, sealing plate 6 and piston 4 are connected. After removing both from the outer casing 1, when the sealing disc 6 and piston 4 need to be separated and replaced individually, to remove the piston 4, first press down the limiting head 27. Then, the limiting head 27 retracts into the limiting groove 25 and squeezes the elastic element 26. Next, move the pin 23 to make it move the limiting head 27 within the mating through hole 22 until the pin 23 is completely separated from the mating through hole 22. Then, move the piston 4 away from the mating sleeve 19. The movement of the piston 4 will cause the rotating rod 18 to separate from the mating sleeve 19, thus allowing the piston 4 to be removed individually. To remove the sealing disc 6 independently, rotate the adjusting rod 7. The rotation of the adjusting rod 7 will cause the threaded head 21 to rotate. The threaded head 21 will rotate within the mating threaded hole 20 until it separates from the mating threaded hole 20.The above operation involves removing the piston 4 and sealing disc 6 by manipulating the docking assembly 5. Installing the sealing disc 6 and piston 4 is simply a matter of reversing the above steps.

[0025] refer to Figure 1 , Figure 2 and Figure 3 A sealing disc 6 is movably fitted onto the docking assembly 5 to seal the area of ​​the inner wall of the outer casing 1 near the disassembly cover 29. The sealing disc 6 is movably fitted onto the docking sleeve 19. The distance between the sealing disc 6 and the piston 4 matches the diameter of the inlet pipe 2. When the piston 4 completely seals the outlet pipe 3, the connection position between the inlet pipe 2 and the outer casing 1 is between the sealing disc 6 and the piston 4. This is to ensure that the inlet of the inlet pipe 2 falls between the sealing disc 6 and the piston 4, thus sealing the inlet pipe 2 through the sealing disc 6 and the piston 4 to prevent water leakage. The disc 6 also protects the disassembly cover 29. Since the disassembly cover 29 is not airtight, a sealing disc 6 is designed here for sealing. The top and bottom of the sealing disc 6 are provided with sealing rings 28 at the positions corresponding to the docking sleeve 19 and the adjusting rod 7. The sealing disc 6 and the piston 4 are both movably attached to the inner wall of the outer shell 1 to effectively seal the connection between the sealing disc 6 and the docking sleeve 19 and the adjusting rod 7. The end of the docking assembly 5 away from the piston 4 is provided with an adjusting rod 7. The other end of the adjusting rod 7 passes through the outer shell 1 and extends to the outside of the outer shell 1.

[0026] refer to Figure 1 , Figure 2 and Figure 3A disassembly cover 29 is movably sleeved on the surface of the adjusting rod 7. The disassembly cover 29 is threaded onto the end of the outer casing 1 away from the outlet pipe 3. A positioning component 8 is provided on the disassembly cover 29. One end of the positioning component 8 is attached to the surface of the adjusting rod 7. The positioning component 8 is used to position the adjusting rod 7 to prevent it from rotating with the screw 16 in the adjusting component 12 during operation. The positioning component 8 is used to position the adjusting rod 7 to prevent it from rotating while the adjusting rod 7 moves up and down along the positioning component 8. The positioning component 8 includes a positioning block 9, a threaded through hole 10, and a limiting bolt 11. The positioning block 9 is fixed on the disassembly cover 29 near the adjusting rod 7. The threaded through hole 10 is opened on the positioning block 9. The limiting bolt 11 is movable inside the threaded through hole 10. A flat cut surface is opened on the side of the adjusting rod 7 corresponding to the position of the positioning block 9. One end of the limiting bolt 11 moves on the flat cut surface. When the worn piston 4 and sealing disc 6 need to be removed from the housing 1, the positioning component 8 needs to be moved first. The positioning component 8 allows the adjusting rod 7 and the disassembly cover 29 to move freely. When operating the positioning component 8, the limiting bolt 11 needs to be rotated first so that it moves in the threaded through hole 10 on the positioning block 9. The rotation of the limiting bolt 11 will slowly move away from the upper cut surface of the adjusting rod 7 until the adjusting rod 7 can rotate freely on the disassembly cover 29. Then, the disassembly cover 29 is rotated to separate it from the threads on the housing 1. After the disassembly cover 29 is separated from the housing 1, the disassembly cover 29 and the adjusting component 12 are then removed. The adjusting rod 7 will then drive the sealing disc 6, the docking component 5 and the piston 4 to be removed from the housing 1, and the sealing disc 6 and the docking component 5 can then be replaced.

[0027] refer to Figure 1 , Figure 2 and Figure 3An adjustment assembly 12 for adjusting the movement of the adjusting rod 7 is provided on the side of the positioning block 9 away from the disassembly cover 29. The adjustment assembly 12 includes a positioning ring 13, a rotating ring 14, a connecting rod 15, a screw 16, and an internal threaded hole 17. The positioning ring 13 is fixed to the positioning block 9. The rotating ring 14 is rotatably connected to the inner wall of the positioning ring 13 via a bearing. The connecting rod 15 is fixed to the rotating ring 14, and the other end of the connecting rod 15 is fixed to the screw 16. The internal threaded hole 17 is opened on the end face of the adjusting rod 7 located outside the outer casing 1. The screw 16 is threaded into the inside of the internal threaded hole 17. This operation is premised on the entire flow regulating device being installed and able to move normally. During operation, the limiting bolt 11 on the positioning assembly 8 abuts against the tangential surface of the adjusting rod 7, making it difficult for the adjusting rod 7 to rotate on its own. Rotate the connecting rod 15, which in turn drives the rotating ring 14 and the screw 16 to rotate. The rotating ring 14 rotates freely on the positioning ring 13, while the screw 16 rotates within the internal threaded hole 17. Since the adjusting rod 7 is not easy to rotate, when the screw 16 rotates, it will push the adjusting rod 7 through the internal threaded hole 17, causing the adjusting rod 7 to move into the interior of the housing 1. The movement of the adjusting rod 7 will drive the sealing disc 6 and the piston 4 to move along the inner wall of the housing 1. The flow rate is adjusted by the size of the gap between the piston 4 and the outlet pipe 3 on the housing 1, thus achieving flow rate adjustment. The operation of the entire adjusting assembly 12 is to ensure that the adjusting rod 7 is pushed stably and to avoid the situation where the adjusting rod 7 may be pushed back (due to greater internal pressure that squeezes the piston 4) when manually pressed.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
