An energy-saving boosting valve for pipelines

Abstract

The present invention discloses an energy-saving boosting valve for pipelines, which is applied in the technical field of fluid pipeline accessories. The present invention sets a narrow valve width, a wide valve pipe and a connecting pipe as a structural carrier and a flow route of the fluid. The boosting component is used to assist in pressurizing the fluid. After the fluid enters the wide valve pipe, its flow direction drives the driving turbine to rotate, and the driving turbine drives the pressurizing turbine to rotate through the central axis. When the fluid passes through the connecting pipe at a constant pressure, the water pressure will increase because the diameter of the connecting pipe is smaller than the wide valve pipe. When it contacts the pressurizing turbine and is driven to be discharged, it will be further pressurized, so as to achieve a certain boosting effect when no external power supply is connected. The blocking column can be used to adjust the space inside the narrow valve pipe for the fluid to pass through, so as to adjust the flow rate. When pressurization is not required, the fluid enters the wide valve body to relieve part of the pressure.

Description

Technical Field

[0001] The present invention belongs to the technical field of fluid pipeline accessories, and in particular relates to an energy-saving boosting valve for pipelines. Background Art

[0002] Equipment and accessories based on fluid pipeline transportation sometimes need to pressurize the fluid in the pipeline. More specifically, when pressurizing through a booster valve, the gas or liquid pipeline is mostly connected to the booster valve, and the system pressure is increased to reach the pressure required by the system.

[0003] Chinese patent CN102126489B discloses an emergency boost valve, including a boost valve sleeve connected to a train pipe, an auxiliary air cylinder and a volume chamber respectively, a boost valve stem is arranged in the boost valve sleeve, and a pull rod, a pull rod sleeve and a plunger are arranged in the boost valve stem. This invention effectively controls the on-off state of the auxiliary air cylinder and the volume chamber during the two actions of increasing the pressure in the volume chamber from 0 to 400kPa and suddenly accelerating and relieving the working air cylinder pressure from 450kPa to 50-100kPa to zero by moving the boost valve stem, pull rod and plunger in the boost valve sleeve, and coordinating with the setting of the positions of each sealing ring, thereby achieving the goal of increasing the pressure in the volume chamber from 0 to 400kPa, and the boost time should not be greater than 4s, while also meeting the two requirements of suddenly accelerating and relieving the working air cylinder pressure to zero when it drops from 450kPa to 50-100kPa.

[0004] Existing energy-saving booster valves for pipelines mostly require an external power source or gas source to pressurize the transport medium when in use. In remote areas or places without electricity, it is easy for them to fail to pressurize normally due to the lack of power supply. In addition, most booster valves cannot reduce water pressure when pressurization is not required, such as when maintaining pipe sections.

[0005] Based on the above-mentioned problems, we found that it is difficult for the energy-saving booster valves used in pipelines in the existing technology to avoid the above problems at the same time. Even if they can be solved, external energy supply or pressure relief equipment is required, which leads to increased costs and increased equipment volume. Therefore, we propose an energy-saving booster valve for pipelines that can relieve pressure on the medium when boosting is not required and does not require additional energy supply. Summary of the Invention

[0006] The purpose of the present invention is to provide an energy-saving boosting valve for pipelines. The valve has the advantages of being able to relieve pressure on a medium when boosting is not required and requiring no additional energy supply.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: an energy-saving booster valve for a pipeline, comprising a wide valve pipe, a narrow valve pipe is provided on the right side of the wide valve pipe, the right side of the wide valve pipe and the narrow valve pipe are integrally formed, a connecting pipe is bolted to the top of the wide valve pipe, the bottom of the connecting pipe is bolted to the top of the narrow valve pipe, a booster assembly is provided on the inside of the wide valve pipe, and threaded flanges are provided on the left side of the outside of the wide valve pipe and the right side of the outside of the narrow valve pipe;

[0008] The supercharging assembly includes a bracket, a bearing is bolted to the inner side of the bracket, a central shaft is rotatably connected to the inner side of the bearing, a driving turbine is bolted to the left side of the outer side of the central shaft, and a pressurizing turbine is bolted to the right side of the outer side of the central shaft.

[0009] The above technical solution is adopted, by setting a narrow valve width, a wide valve pipe and a connecting pipe as a structural carrier and a flow route of the fluid, and the set boosting component is used to assist in pressurizing the fluid. After the fluid enters the wide valve pipe, its flow direction will drive the driving turbine to rotate, and the driving turbine drives the pressurizing turbine to rotate through the central axis. When the fluid passes through the connecting pipe at a constant pressure, the water pressure will increase because the diameter of the connecting pipe is smaller than the wide valve pipe. When it contacts the pressurizing turbine and is driven to be discharged, it will be further pressurized, so as to achieve a certain boosting effect when an external power supply is not connected. The set threaded flange can be used to connect the structure to the external medium pipeline.

[0010] The present invention is further configured as follows: an outlet pipe is provided at the top of the right side of the narrow valve tube, an adjusting screw is threadedly connected to the inner wall of the outlet pipe, and a blocking column is bolted to the bottom of the adjusting screw.

[0011] By adopting the above technical solution, by setting up an adjusting screw and a blocking column, when the adjusting screw is rotated along the outlet pipe, the blocking column connected to it will also move in the vertical direction to adjust the space inside the narrow valve tube for fluid to pass through, thereby adjusting the flow rate.

[0012] The present invention is further configured as follows: a spherical fitting frame is bolted to the bottom of the inner wall of the narrow valve tube, a blocking block is bolted to the front side and the rear side of the top of the spherical fitting frame, and the blocking block and the inner side of the spherical fitting frame are used in conjunction with the blocking column.

[0013] By adopting the above technical solution, by arranging a spherical matching frame to cooperate with the blocking block, when the blocking column falls, it will be in close contact with the blocking block and the inner side of the spherical matching frame, so that the sealing between the structures is better.

[0014] The present invention is further configured as follows: a guide frame is bolted to the top of the inner wall of the narrow valve tube, the guide frame is located at the bottom of the connecting tube, and the guide frame is arranged on the top of the pressure turbine.

[0015] By adopting the above technical solution and providing a guide frame, the fluid will be guided to the position of the pressure turbine when it flows into the narrow valve tube, so that the pressure can be increased, making the structure more reasonable.

[0016] The present invention is further configured as follows: the bottom of the wide valve tube is bolted to a secondary shell, the inner wall of the secondary shell is bolted to a support spring, the top of the support spring is bolted to a piston block, and the outer side of the piston block is in close contact with the inner wall of the secondary shell.

[0017] By adopting the above technical solution, by setting up a sub-shell and a piston block, when there is no need for pressurization, the fluid entering the wide valve body will relieve part of the pressure and press the piston block to move downward along the sub-shell. At the same time, the support spring will deform, and when the fluid stops passing, the support spring will rebound to reset the piston block.

[0018] The present invention is further configured as follows: a limiting telescopic rod is bolted to the bottom of the inner wall of the secondary housing, and the top of the limiting telescopic rod is bolted to the bottom of the piston block.

[0019] By adopting the above technical solution, by providing a limiting telescopic rod, the movement of the piston block will be limited when it moves, avoiding the displacement that is difficult to reset, such as rotation or tilting.

[0020] The present invention is further configured as follows: a dehumidification hole is provided at the bottom of the auxiliary shell, a functional sheet is provided at the top of the inner wall of the auxiliary shell, the outer side of the functional sheet is in close contact with the auxiliary shell, the top of the wide valve tube is bolted with a mating seat, the top of the mating seat is bolted with a limiting frame, the inner side of the mating seat is threadedly connected to a control screw, the bottom of the control screw is bolted with an extension rod, and the bottom of the extension rod is bolted to the top of the functional sheet.

[0021] By adopting the above technical solution, a moisture-draining hole is set, and when water accumulates inside the sub-shell, it will be discharged through the moisture-draining hole, avoiding the abnormal use caused by long-term water accumulation. The functional plate is used to block the position of the piston block during pressurization so that it will not be displaced due to the pressure in the wide valve tube, so as to ensure the normal operation of the structure required for pressurization. The control screw is set to drive the functional plate to move in the vertical direction through the extension rod when it rotates along the mating seat to control whether the piston block is used.

[0022] The present invention is further configured as follows: a connecting rod is bolted to the top of the control screw, and a handle is bolted to the top of the connecting rod.

[0023] By adopting the above technical solution, by providing a connecting rod, the control screw can be easily connected to the handle, and the connecting rod and the control screw connected thereto can be conveniently rotated through the handle.

[0024] The present invention is further configured as follows: a matching tube is provided on the left side of the wide valve tube, the inner walls of the matching tube and the wide valve tube are bolted with a clamping ring, a first filter screen is provided on the left side of the right clamping ring, a second filter screen is provided on the left side of the first filter screen, and the left side of the second filter screen is clamped with the left clamping ring.

[0025] By adopting the above technical solution, by arranging the matching tube and the clamping ring, the first filter screen and the second filter screen can be easily installed, and the fluid medium can be filtered when passing through, making the structure more functional.

[0026] The present invention is further configured as follows: a stabilizing ring is bolted to the outside of the mating tube, a rotating ring is rotatably connected to the outside of the stabilizing ring, a mating ring is bolted to the left side of the outside of the wide valve tube, and the outside of the mating ring is threadedly connected to the rotating ring.

[0027] By adopting the above technical solution, by setting a stabilizing ring, a rotating ring and a matching ring, when the first filter screen and the second filter screen need to be replaced or disassembled, the rotating ring can be unscrewed along the matching ring to disconnect the matching tube and the wide valve tube, making the connection more flexible.

[0028] In summary, the present invention has the following beneficial effects:

[0029] By setting a narrow valve width, a wide valve tube and a connecting tube as a structural carrier and a flow route of the fluid, a boosting component is set up to assist in pressurizing the fluid. After the fluid enters the wide valve tube, its flow direction will drive the driving turbine to rotate, and the driving turbine drives the pressurization turbine to rotate through the central axis. When the fluid passes through the connecting tube at a constant pressure, the water pressure will increase because the diameter of the connecting tube is smaller than the wide valve tube. When it contacts the pressurization turbine and is driven to be discharged, it will be further pressurized, so as to achieve a certain boosting effect when no external power supply is required. The set blocking column can be used to adjust the space inside the narrow valve tube for the fluid to pass through, so as to adjust the flow rate. When pressurization is not required, the fluid entering the wide valve body will relieve part of the pressure and press the piston block to make it move downward along the sub-shell. At the same time, the support spring will deform. When the fluid stops passing, the support spring rebounds to reset the piston block, making the structure more flexible to use.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Example 1:

[0038] refer to Figure 1-5 An energy-saving booster valve for a pipeline comprises a wide valve tube 1, a narrow valve tube 2 being provided on the right side of the wide valve tube 1, the right side of the wide valve tube 1 and the narrow valve tube 2 being integrally formed, a connecting tube 3 being bolted to the top of the wide valve tube 1, the bottom of the connecting tube 3 being bolted to the top of the narrow valve tube 2, a booster assembly 4 being provided on the inside of the wide valve tube 1, and a threaded flange 5 being provided on the left side of the outside of the wide valve tube 1 and the right side of the outside of the narrow valve tube 2;

[0039] The boost assembly 4 includes a bracket 401, a bearing 402 bolted to the inner side of the bracket 401, and a central shaft 403 rotatably connected to the inner side of the bearing 402. A driving turbine 404 is bolted to the left side of the outer side of the central shaft 403, and a pressurizing turbine 405 is bolted to the right side of the outer side of the central shaft 403. By setting a narrow valve width, a wide valve pipe 1 and a connecting pipe 3, as a structural carrier and a flow route of the fluid, the boost assembly 4 is set to assist in pressurizing the fluid. After the fluid enters the wide valve pipe 1, its flow direction will drive the driving turbine 404 to rotate, and the driving turbine 404 drives the pressurizing turbine 405 to rotate through the central shaft 403. When the fluid passes through the connecting pipe 3 at a constant pressure, the water pressure will increase because the diameter of the connecting pipe 3 is smaller than that of the wide valve pipe 1. When it contacts the pressurizing turbine 405 and is driven to be discharged, it will be further pressurized, so as to achieve a certain pressurization effect when an external power supply is not required.

[0040] like Figure 3As shown, an outlet pipe 6 is provided at the top of the right side of the narrow valve tube 2, and an adjusting screw 7 is threadedly connected to the inner wall of the outlet pipe 6. A blocking column 8 is bolted to the bottom of the adjusting screw 7. By arranging the adjusting screw 7 and the blocking column 8 in coordination, when the adjusting screw 7 is rotated along the outlet pipe 6, the blocking column 8 connected thereto will also move in the vertical direction to adjust the space inside the narrow valve tube 2 for the fluid to pass through, thereby adjusting the flow rate.

[0041] like Figure 3 As shown, a spherical fitting frame 9 is bolted to the bottom of the inner wall of the narrow valve tube 2, and a blocking block 10 is bolted to the front side and the rear side of the top of the spherical fitting frame 9. The blocking block 10 and the inner side of the spherical fitting frame 9 are used in conjunction with the blocking column 8. By arranging the spherical fitting frame 9 to cooperate with the blocking block 10, when the blocking column 8 falls, it will be in close contact with the blocking block 10 and the inner side of the spherical fitting frame 9, so that the sealing between the structures is better.

[0042] like Figure 5 As shown, a guide frame 11 is bolted to the top of the inner wall of the narrow valve tube 2, and the guide frame 11 is located at the bottom of the connecting tube 3. The guide frame 11 is set on the top of the pressurizing turbine 405. By setting the guide frame 11, when the fluid flows into the narrow valve tube 2, it will be guided to the position of the pressurizing turbine 405, so that it can achieve the pressurization effect, making the structure more reasonable.

[0043] Brief description of the usage process: When the fluid enters the wide valve tube 1, it will come into contact with the driving turbine 404 of the boosting assembly 4, and the central shaft 403 will be driven to rotate by the water flow. The set pressurizing turbine 405 will also rotate with the central shaft 403. When the liquid enters the narrow valve tube 2 through the connecting pipe 3, it will be guided to the pressurizing turbine 405 due to the guide frame 11, and because of the rotation of the pressurizing turbine 405, it is pressurized and discharged from the narrow valve tube 2. When it is necessary to control the water output, the adjusting screw 7 is rotated along the outlet pipe 6. At this time, the blocking column 8 connected to it will also move in the vertical direction to adjust the space inside the narrow valve tube 2 for the fluid to pass through.

[0044] Example 2:

[0045] refer to Figure 1-4 , an energy-saving booster valve for a pipeline, comprising a wide valve tube 1, a narrow valve tube 2 is arranged on the right side of the wide valve tube 1, the right side of the wide valve tube 1 and the narrow valve tube 2 are integrally formed, and a threaded flange 5 is provided on the left side of the outer side of the wide valve tube 1 and the right side of the outer side of the narrow valve tube 2. The wide valve tube 1 and the narrow valve tube 2 are arranged to cooperate as the structural main body and the support position of the internal structure, and the threaded flange 5 is used to connect the structure and the pipeline.

[0046] like Figure 2As shown, the bottom of the wide valve tube 1 is bolted with a sub-shell 12, the inner wall of the sub-shell 12 is bolted with a support spring 13, and the top of the support spring 13 is bolted with a piston block 14. The outer side of the piston block 14 is in close contact with the inner wall of the sub-shell 12. By arranging the sub-shell 12 and the piston block 14 to cooperate with each other, when there is no need for pressurization, the fluid entering the wide valve tube 2 will relieve part of the pressure and press the piston block 14 to move it downward along the sub-shell 12. At the same time, the support spring 13 will be deformed, and when the fluid stops passing through, the support spring 13 rebounds to reset the piston block 14.

[0047] like Figure 2 As shown, the bottom of the inner wall of the secondary housing 12 is bolted with a limiting telescopic rod 15, and the top of the limiting telescopic rod 15 is bolted to the bottom of the piston block 14. By setting the limiting telescopic rod 15, the movement of the piston block 14 will be limited when it moves, avoiding rotation or tilting and other displacements that are difficult to reset.

[0048] like Figure 2 As shown, a dehumidification hole 16 is provided at the bottom of the sub-shell 12, and a functional piece 17 is provided at the top of the inner wall of the sub-shell 12. The outer side of the functional piece 17 is in close contact with the sub-shell 12. The top of the wide valve tube 1 is bolted with a mating seat 18, and the top of the mating seat 18 is bolted with a limiting frame 19. The inner side of the mating seat 18 is threadedly connected with a control screw 20, and the bottom of the control screw 20 is bolted with an extension rod 21, and the bottom of the extension rod 21 is bolted to the top of the functional piece 17. By setting the dehumidification hole 16, when water accumulates inside the sub-shell 12, it will be discharged through the dehumidification hole 16 to avoid normal use caused by long-term water accumulation. The functional piece 17 is used to block the position of the piston block 14 during pressurization, so that it will not be displaced due to the pressure in the wide valve tube 1, so as to ensure the normal operation of the structure required for pressurization. When the control screw 20 rotates along the mating seat 18, it will drive the functional piece 17 to move in the vertical direction through the extension rod 21 to control whether the piston block 14 is used.

[0049] like Figure 2 As shown, the top of the control screw 20 is bolted with a connecting rod 22, and the top of the connecting rod 22 is bolted with a handle 23. By setting the connecting rod 22, the control screw 20 can be easily connected to the handle 23, and the connecting rod 22 and the control screw 20 connected thereto can be conveniently rotated through the handle 23.

[0050] like Figure 4As shown, a matching tube 24 is provided on the left side of the wide valve tube 1, and a clamping ring 25 is bolted to the inner wall of the matching tube 24 and the wide valve tube 1. A first filter screen 26 is provided on the left side of the right clamping ring 25, and a second filter screen 27 is provided on the left side of the first filter screen 26. The left side of the second filter screen 27 is clamped with the left clamping ring 25. By arranging the matching tube 24 and the clamping ring 25, the first filter screen 26 and the second filter screen 27 can be easily installed, and the fluid medium can be filtered when passing through, making the structure more functional.

[0051] like Figure 4 As shown, the outer side of the matching tube 24 is bolted with a stabilizing ring 28, and the outer side of the stabilizing ring 28 is rotatably connected to a rotating ring 29. The left side of the outer side of the wide valve tube 1 is bolted with a matching ring 30, and the outer side of the matching ring 30 is threadedly connected to the rotating ring 29. By arranging the stabilizing ring 28 to cooperate with the rotating ring 29 and the matching ring 30, when the first filter screen 26 and the second filter screen 27 need to be replaced or disassembled, the rotating ring 29 can be unscrewed along the matching ring 30, so that the matching tube 24 and the wide valve tube 1 are disconnected, making the connection more flexible.

[0052] Brief description of the usage process: Connect the wide valve tube 1 and the narrow valve tube 2 to the pipeline through the threaded flange 5. The fluid medium will be filtered by the first filter 26 and the second filter 27 when passing through the wide valve tube 1. When there is no need to pressurize the fluid, rotate the control screw 20 along the matching seat 18. The functional piece 17 can be moved by the extension rod 21 to expose the position of the piston block 14. At this time, the fluid will contact and press the piston block 14 to move it downward along the sub-housing 12. At the same time, the support spring 13 will be deformed. When the fluid stops passing through, the support spring 13 rebounds to reset the piston block 14.
