Description

Technical Field

[0001] This invention belongs to the field of water pump unit piping systems, and specifically relates to a water pump unit piping system. Background Technology

[0002] Water hammer refers to the phenomenon in a closed pipeline system where a sudden change in fluid flow causes significant pressure fluctuations and vibrations. Its instantaneous pressure can greatly exceed normal pressure and often has destructive effects. When an open valve suddenly closes or the water pump stops, the water flow exerts pressure on the pipeline, valve, or pump. This means that if a sudden power outage occurs during water supply, the impact of water hammer can easily damage the pipeline, valve, or pump unit. Current technology in use...

[0003] 1. Water hammer is often absorbed by installing water hammer eliminators. However, in the process of supplying water through long pipelines, when water hammer occurs, the water hammer impact is large and the water hammer eliminator cannot eliminate all the water hammer impact in a timely and effective manner, which makes the valves and pumps of the water pump unit pipeline easy to be damaged.

[0004] 2. If a mechanical valve is used as the main valve of the pipeline, it cannot be closed in time when water hammer occurs, which can easily cause backflow in the pipeline to drive the water pump to rotate, thus easily damaging the water pump. If an electronic valve is used, it cannot be closed in time during a power outage, and the valve is also prone to loss of control due to the failure of the electronic circuit board, making it inconvenient as a main valve.

[0005] 3. Even if the electrically controlled valve closes in time and the water hammer does not damage the valves and pumps in the pipeline, the water that has stopped flowing in the long pipeline is still likely to damage the main control valve due to its weight. Especially in the case of a sudden power outage that causes the pump to stop pumping water, the staff cannot respond in time. The main control valve is subjected to weight for a long time, which can easily lead to damage to the main control valve. If the water in the pipeline is discharged directly, it will easily lead to waste of water resources. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To overcome the shortcomings of existing technologies, a water pump unit pipeline system is proposed to address the issue that existing technologies often rely on water hammer eliminators to absorb water hammer during use. However, in long pipeline supply processes, when water hammer occurs, the impact is significant, and the water hammer eliminator cannot effectively eliminate all water hammer impacts in a timely manner, leading to easy damage to the valves and pumps in the water pump unit pipeline.

[0008] Secondly, in order to solve the problem of existing technology, if the main valve of the pipeline is a mechanical valve, it cannot be closed in time when water hammer occurs, which can easily cause back water in the pipeline to drive the water pump to rotate, thus easily damaging the water pump. If an electronic valve is used, it cannot be closed in time during a power outage, and the valve is also prone to loss of control due to the failure of the electronic circuit board, which is inconvenient as a main valve.

[0009] Furthermore, when using existing technologies, even if the electrically controlled valves are closed in time and the water hammer does not damage the valves and pumps in the pipeline, the water that has stopped being transported in the long pipeline is still prone to damage to the main control valve due to its weight. Especially in the case of a sudden power outage that causes the pump to stop pumping water, the staff cannot respond in time, and the main control valve is prone to damage due to prolonged load. If the water in the pipeline is discharged directly, it will easily lead to a waste of water resources.

[0010] (II) Technical Solution

[0011] This invention is achieved through the following technical solution: This invention proposes a water pump unit pipeline system, the structure of which includes an assembly frame, a transmission gearbox, a linkage shaft, a drain pipe, a water turbine, a accumulator valve, a water delivery pipe, a water hammer valve, a main control valve, a water pump, a connecting pipe, a linkage box, and a shaft clutch. The water pump is connected to one end of the main control valve through the connecting pipe, and the other end of the main control valve is connected to the water delivery pipe through the water hammer valve. The water hammer valve is also connected to the drain pipe. The water turbine is assembled inside the drain pipe. The accumulator valve is assembled on the drain pipe and located between the water turbine and the water hammer valve. The accumulator valve is synchronously controlled with the main control valve through the linkage box. The water turbine drives the main control valve to close through the linkage shaft, the transmission gearbox, and the shaft clutch. The assembly frame is used for assembling and supporting the transmission gearbox and the linkage box.

[0012] During normal water supply, the water hammer valve is used to close the connection between the drain pipe and the water supply pipe to prevent normal water supply from being discharged from the drain pipe.

[0013] When water hammer occurs, the water hammer prevention valve is used to open the connection between the drain pipe and the water supply pipe while closing the connection between the connecting pipe and the water supply pipe, so that the water head of the water hammer will be discharged from the drain pipe, avoiding the main control valve at the water supply pipe from being impacted by the water hammer, and better ensuring the safety of the main control valve and the water pump.

[0014] The accumulator valve closes the connection between the drain pipe and the water supply pipe after the main control valve closes the connection between the connecting pipe and the water supply pipe, thus preventing excessive water loss from the water supply pipeline.

[0015] Furthermore, the main control valve consists of a handle and a valve body. The handle is used to rotate and control the opening and closing of the valve body. The end of the handle away from the valve body is connected to a shaft clutch at the same center. The linkage box consists of a first gear, a shaft, a box body, a second gear, and a third gear. The shaft is assembled in the box body. The first gear and the second gear are respectively assembled at both ends of the shaft. The shaft drives the accumulator valve to open and close through the first gear. The third gear is fixedly connected to the handle at the same center. The shaft meshes with the third gear through the second gear.

[0016] Furthermore, the side end face of the handle penetrates the housing and is fitted with the housing with a clearance.

[0017] Furthermore, the shaft head clutch is used to link the main control valve and the transmission gearbox when the main control valve is open, and to disconnect the link between the main control valve and the transmission gearbox when the main control valve is closed.

[0018] (III) Beneficial Effects

[0019] One of the above technical solutions has the following advantages or beneficial effects:

[0020] 1) To address the issue that existing technologies often rely on water hammer eliminators to absorb water hammer, which can be problematic in long pipelines where the impact is significant and eliminators cannot effectively eliminate all impacts, leading to damage to valves and pumps, a water hammer eliminator is installed between the main control valve and the water supply pipeline. This valve, connected to a drainage pipeline, prevents water hammer from impacting the main control valve and draining the water hammer when it occurs. This design significantly reduces the force of water hammer compared to a water hammer absorber, allowing it to drain even in long pipelines and effectively preventing damage to pipelines, main control valves, and pumps.

[0021] 2) To address the shortcomings of existing technologies, where mechanical valves in pipelines cannot close promptly during water hammer, leading to backflow that could damage the water pump, and electronic valves are also problematic due to potential issues like power outages and circuit board malfunctions causing them to malfunction, a solution is proposed. This solution involves installing a water turbine in the drainage pipeline in addition to the existing water hammer valve. The turbine is linked to the main control valve handle, automatically closing the main control valve as water flows through the drainage pipe. This eliminates the need for electric control, ensuring reliable valve closure and simultaneously eliminating water hammer while protecting the water pump by closing the main control valve.

[0022] 3) To address the issue that even if the electrically controlled valve closes promptly and water hammer does not damage the valves and pumps in the pipeline, the weight of water stopped flowing in long pipelines can still damage the main control valve, especially in the event of a sudden power outage causing the pump to stop pumping. In such cases, staff cannot respond promptly, and the main control valve is subjected to prolonged weight, easily leading to damage. Directly discharging the water from the pipeline results in water waste. By installing a accumulator valve linked to the main control valve, the accumulator valve automatically closes the drain pipe when the main control valve closes, preventing the continued discharge of water from the long pipeline and thus avoiding waste. Simultaneously, combined with a water hammer prevention valve, the water pressure in the pipeline is distributed between the water hammer prevention valve and the accumulator valve, preventing the water pressure from directly acting on the main control valve. This better ensures the safety of the main control valve and facilitates pipeline safety and water conservation when staff cannot respond promptly. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0032] Example 1:

[0033] This invention provides a water pump unit piping system: its structure includes an assembly frame a, a transmission gearbox b, a linkage shaft c, a drain pipe d, a water turbine e, a accumulator valve f, a water delivery pipe g, a water hammer valve h, a main control valve i, a pump j, a connecting pipe k, a linkage box l, and a shaft clutch m. The pump j is connected to one end of the main control valve i via the connecting pipe k. The other end of the main control valve i is connected to the water delivery pipe g via the water hammer valve h. The water hammer valve h is also connected to the drain pipe d. The water turbine e is installed inside the drain pipe d, and the accumulator valve f is installed on the drain pipe d. Located between the turbine e and the water hammer valve h, the accumulator valve f is synchronously controlled with the main control valve i through the linkage box l. The turbine e drives the main control valve i to close through the linkage shaft c, the transmission gearbox b, and the shaft head clutch m. The shaft head clutch m is used to prevent the turbine e from still being driven by the main control valve i after the main control valve i is closed, which would cause damage to the turbine e or the main control valve i. Adjusting the transmission ratio in the transmission gearbox b can adjust the time when the turbine e drives the main control valve i to close. The assembly frame a is used for the assembly support of the transmission gearbox b and the linkage box l.

[0034] During normal water supply, the water hammer valve h is used to close the connection between the drain pipe d and the water supply pipe g, preventing normal water supply from being discharged from the drain pipe;

[0035] When water hammer occurs, the water hammer prevention valve h is used to open the connection between the drain pipe d and the water supply pipe g while closing the connection between the connecting pipe k and the water supply pipe g, so that the water head of the water hammer will be discharged from the drain pipe, avoiding the main control valve at the water supply pipe from being impacted by the water hammer, and better ensuring the safety of the main control valve and the water pump.

[0036] The accumulator valve f closes the connection between the drain pipe d and the water supply pipe g after the main control valve i closes the connection between the connecting pipe k and the water supply pipe g, to prevent excessive water loss in the water supply pipeline.

[0037] Furthermore, the main control valve i consists of a handle i1 and a valve body i2. The handle i1 is used to rotate and control the opening and closing of the valve body i2. The end of the handle i1 away from the valve body i2 is connected to a shaft clutch m at the same center. The linkage box l consists of a first gear l1, a shaft l2, a box body l3, a second gear l4, and a third gear l5. The shaft l2 is assembled inside the box body l3. The two ends of the shaft l2 are respectively equipped with the first gear l1 and the second gear l4. The shaft l2 drives the accumulator valve f to open and close through the first gear l1. The third gear l5 is fixedly connected to the handle i1 at the same center. The shaft l2 meshes with the third gear l5 through the second gear l4.

[0038] Furthermore, the side end face of the handle i1 penetrates through the housing l3 and is clearance-fitted with the housing l3.

[0039] Furthermore, the shaft head clutch m is used to link the main control valve i with the transmission gearbox b when the main control valve i is open, and to disconnect the linkage between the main control valve i and the transmission gearbox b when the main control valve i is closed.

[0040] Furthermore, the drain pipe d is connected to a water storage tank at the end away from the turbine e.

[0041] During normal water supply, the water pump j draws water through the connecting pipe k → water hammer valve h → water supply pipe g because the drain pipe d is closed by the water hammer valve h. When a water hammer occurs, the water hammer valve h closes the connection between the connecting pipe k and the water hammer valve h because the water pump j stops supplying water. At the same time, the water hammer valve h opens the connection with the drain pipe d, so that the water hammer head is blocked by the water hammer valve h and discharged from the drain pipe d to the water storage tank. The water hammer in the long pipeline will not act on the connecting pipe k, so that the main control valve i installed on the connecting pipe k can avoid being damaged by the water hammer, and further prevent the water pump j from being impacted by the water hammer. At the same time, the water hammer is discharged and eliminated directly through the drain pipe d, which can greatly improve the upper limit compared with the water hammer eliminator. Even if a water hammer occurs in a long pipeline, it can be discharged and released, which can effectively avoid the harm of water hammer. In addition, the water discharged to the water storage tank can be pumped and used again when the normal water supply is restored, further reducing the waste of water resources.

[0042] Furthermore, during pipeline use, when drain pipe d is draining water, the water turbine e of drain pipe d will operate due to the water flow. This causes the water turbine e to drive the handle i1 to rotate through the transmission gearbox b, linkage shaft c, and shaft head clutch m, enabling the main control valve i to automatically close. After the main control valve i closes, the shaft head clutch m automatically disconnects from the handle i1, preventing damage to the water turbine e or the handle i1. This eliminates the need for manual closing of the main control valve i and also eliminates the need for electronic valves, ensuring the reliability of valve closure and further preventing water hammer valve h from leaking and causing the water pump j to rotate and be damaged.

[0043] In long pipeline transportation, especially in water supply processes such as those in mines, water pipelines can be hundreds of meters long. If a drain pipe d is used to eliminate water hammer, failure to close the drain pipe d in time can easily lead to a large waste of water resources. In this pipeline system, when the main control valve i is closed, the handle i1 will also drive the accumulator valve f to accumulate power through the linkage box l. When the main control valve i is completely closed, the accumulator valve f will release the power and instantly close the drain pipe d, preventing the continued discharge of water in the long pipeline and causing waste. At the same time, after the pipeline stops draining, the water pressure in the pipeline will be shared by the water hammer valve h and the accumulator valve f, and the water pressure in the pipeline will not directly act on the main control valve i, thus better ensuring the safety of the main control valve i. The pipeline system is free from manual control throughout, which facilitates better protection of pipeline safety and water conservation when staff cannot handle the situation in time.

[0044] Example 2:

[0045] Compared to Embodiment 1, this embodiment discloses the specific structure of the waterproof hammer valve h while keeping the rest of the structure unchanged. The waterproof hammer valve h consists of a three-way pipe h1, a bend h2, a valve ball h3, a main valve groove h4, a first valve port h5, a main valve tube h6, a second valve port h7, a third valve port h8, and a fourth valve port h9. The main valve tube h6 is a vertically placed tube, with both ends slightly bent to one side. The main valve tube h6 has a main valve groove h4 with the same structure as the tube body inside. The valve ball h3 is fitted inside the main valve groove h4 with a clearance fit. The first valve port h5 is located at the bottom of the main valve tube h6 and is connected to the connecting pipe k. When the valve ball h3 slides down to the bottom of the main valve groove h4, the valve ball h3 exactly covers the... At the junction of the first valve port h5 and the main valve slot h4, the side end face of the main valve pipe h6 is provided with a fourth valve port h9, which is an upwardly inclined valve port. The top of the main valve pipe h6 is provided with a third valve port h8, and the top inclined end of the main valve pipe h6 is provided with a second valve port h7. The second valve port h7 is connected to the drain pipe d. When the valve ball h3 rises to the top of the main valve slot h4, the valve ball h3 simultaneously seals the second valve port h7 and the third valve port h8. The top of the main valve pipe h6 is connected to a three-way pipe h1 through the third valve port h8. The top of the three-way pipe h1 is connected to the water supply pipe g. The side of the three-way pipe h1 is a downwardly inclined pipe opening. The side end face of the three-way pipe h1 is connected to the fourth valve port h9 through a bend pipe h2. The curvature of the bend pipe h2 is an obtuse angle.

[0046] Furthermore, the diameter of the valve ball h3 is larger than the diameter of the first valve port h5, and the diameters of the second valve port h7, the third valve port h8, and the fourth valve port h9 are all the same as the diameter of the first valve port h5.

[0047] Furthermore, the first valve port h5, the second valve port h7, the third valve port h8, and the fourth valve port h9 are all connected to the main valve slot h4.

[0048] During normal water supply, the water pressure will cause the valve ball h3 to rise in the main valve groove h4 until the valve ball h3 rises to the top of the main valve groove h4, at which point the connection between the second valve port h7 and the drain pipe d will be closed. At the same time, the connection between the third valve port h8 and the tee pipe h1 will also be closed. When the water is delivered to the fourth valve port h9 of the main valve pipe h6, a portion of the water will be diverted from the fourth valve port h9. The water diverted from the fourth valve port h9 will be delivered from the bend pipe h2 to the tee pipe h1. After the water in the bend pipe h2 enters the tee pipe h1, part of the water will flow from the tee pipe h1 to the third valve port h8 and be blocked by the valve ball h3. The rest will flow through the tee pipe h1 to the water supply pipe g for delivery. The lengths of the tee pipe h1 and the bend pipe h2 can be adjusted to prevent the speed at which the water flows from the tee pipe h1 to the third valve port h8 from being faster than the speed at which the valve ball h3 is pressed by the water to close the connection between the second valve port h7 and the drain pipe d.

[0049] When a sudden power outage causes the water pump to stop, the water in the pipeline, during its descent, will preferentially enter the main valve slot h4 from the tee pipe h1 and the third valve port h8 due to the straight pipe and gravity. Secondly, water will enter the bend pipe h2 from the slot on the side end of the tee pipe h1, and then flow into the main valve slot h4 via the bend pipe h2 and the fourth valve port h9. Water entering the main valve slot h4 from the third valve port h8 will preferentially press against the valve ball h3 due to its weight and the straight pipe's transport, causing the valve ball h3 to fall rapidly to the bottom of the main valve slot h4 due to its own weight and the water pressure in the pipeline, sealing the connection between the main valve slot h4 and the first valve port h5. Furthermore, water entering the main valve slot h4 from the third valve port h8, after pressing against the valve ball h3 and falling, will also flow from the second valve port h7. The water flowing into the main valve slot h4 from the fourth valve port h9 needs to be slower than the time it takes for the valve ball h3 to descend to the bottom of the connection between the main valve slot h4 and the fourth valve port h9. This time can be achieved by adjusting the length of the three-way pipe h1 and the bend h2, so that the valve ball h3 can descend smoothly to the bottom of the main valve slot h4, thus preventing water hammer from acting on the main control valve i. After the water hammer head drives the valve ball h3 to close the connection between the main valve slot h4 and the fourth valve port h9, it will enter the drain pipe d from the second valve port h7 and be discharged, thereby reducing the damage caused by water hammer. The equipment is free from electric control throughout the process, and because it is driven by water hammer and water pressure, it can achieve a stable automatic opening and closing effect, and reliably prevent the damage caused by water hammer.

[0050] The obtuse-angle bend h2 of the equipment, combined with the upwardly inclined fourth valve port h9 and the downwardly inclined tee pipe h1, can better reduce the resistance of water flow. The pipe structure with the upper end of the main valve pipe h6 slightly bent to one side can make the valve ball h3 better withstand the pressure of the water flow and fit and seal the second valve port h7.

[0051] Example 3:

[0052] Compared to Embodiment 1, this embodiment discloses the specific structure of the accumulator valve f while keeping the rest of the structure unchanged. The accumulator valve f is composed of a screw f1, a fourth gear f2, a limiting plate f3, a valve body assembly plate f4, a valve plate f5, a valve plate groove f6, a water passage hole f7, a first compression spring f8, a screw receiving groove f9, a first clamping plate f10, a second compression spring f11, a clamping plate connecting plate f12, a second clamping plate f13, and a clamping plate groove f14. A water passage hole f7 is provided through one side of the valve body assembly plate f4, and the valve body assembly plate f4 is connected to the drain pipe d through the water passage hole f7. The valve body assembly plate f4 has a valve plate groove f6 on the side through which the water passage hole f7 passes. The valve plate f5 is located in the valve plate groove f6 and can cover the entire water passage hole f7. The valve body assembly plate f4 has a screw receiving groove f9 on the side away from the water passage hole f7. The screw receiving groove f9 communicates with the valve plate groove f6. The limiting plate f3 is located in the screw receiving groove f9. The end of the limiting plate f3 away from the valve plate groove f6 is fixedly connected to one end of the screw f1. The other end of the screw f1 passes through the valve body assembly plate f4. The fourth gear f2 is covered on the screw f1 and threaded with the screw f1. The fourth gear f2 is located within the valve body assembly plate f4. The end of the limiting plate f3 adjacent to the valve plate groove f6 is fixedly connected to one end of the first compression spring f8. The other end of the first compression spring f8 is fixedly connected to the valve plate f5. The limiting plate f3 is clearance-fitted with the screw receiving groove f9. Inside the valve body assembly plate f4, on both sides of the point where the screw receiving groove f9 communicates with the valve plate groove f6, there are retaining plate grooves f14. A retaining plate connecting plate f12 is located within the retaining plate groove f14. A second compression spring f11 is fitted between the retaining plate connecting plate f12 away from the valve plate groove f6 and the retaining plate groove f14. The two ends of the connecting plate f12 away from the second compression spring f11 are respectively fixed with a first clamping plate f10 and a second clamping plate f13. The end of the first clamping plate f10 away from the connecting plate f12 is located in the screw receiving groove f9. The end of the second clamping plate f13 away from the connecting plate f12 is located in the valve plate groove f6. The part of the first clamping plate f10 located in the screw receiving groove f9 is inclined near the limiting plate f3. The part of the second clamping plate f13 located in the valve plate groove f6 is inclined near the valve plate f5. The end face of the valve plate f5 is provided with a groove that fits with the second clamping plate f13 near the screw receiving groove f9.

[0053] Furthermore, the limiting plate f3 cannot rotate within the screw receiving groove f9.

[0054] Furthermore, the valve plate f5 is provided with a second retaining plate f13 at the end adjacent to the screw receiving groove f9, and the end of the retaining plate f13 is an inclined surface that fits with the inclined surface of the second retaining plate f13. The limiting plate f3 is provided with a first retaining plate f10 at the end adjacent to the valve plate groove f6, and the end of the limiting plate f3 is an inclined surface that fits with the inclined surface of the first retaining plate f10.

[0055] In operation, when the turbine drive handle i1 is rotated to close the main control valve i, the third gear l5 on handle i1 drives the first gear l1 mounted on the coaxial rod l2 to rotate. This causes the first gear l1 to drive the fourth gear f2. Since the position of the fourth gear f2 is limited, and the rotation of the screw f1 is limited by the limiting plate f3, the screw f1, which is threadedly connected to the fourth gear f2, will move up or down when the fourth gear f2 rotates. This allows the equipment to drive the screw f1 to lift the limiting plate f3 during the closing of the main control valve i. During the lifting of the limiting plate f3, the limiting plate f... 3 will compress the first compression spring f8, and after the first compression spring f8 is compressed to a certain extent, the limiting plate f3 will press the inclined surface of the first clamping plate f10 through the inclined surface, causing the first clamping plate f10 to drive the clamping plate connecting plate f12 to move into the clamping plate groove f14, causing the second clamping plate f13 connected to the other end of the clamping plate connecting plate f12 to also move into the clamping plate groove f14, causing the second clamping plate f13 to disengage from the latch on the valve plate f5, so that the valve plate f5 will be pressed by the first compression spring f8 to close the water passage hole f7. At this time, the main control valve i is also completely closed. The linkage between the two can be adjusted by the first compression spring f8. The size and number of teeth of gears l1, l4, l5, and f2 are adjusted. When the user manually opens the main control valve i, as the user turns handle i1, handle i1 will drive the fourth gear f2 to rotate in the opposite direction, causing the screw f1 to descend. This causes the screw f1 to drag the valve plate f5 down via the first compression spring f8. When the valve plate f5 descends, it will first be pushed inward by the inclined surface adjacent to the second clamping plate f13. Then, the second clamping plate f13 will enter the valve plate f5 due to the force of the second compression spring f11 pressing against the clamping plate connecting plate f12. The valve plate f5 returns to its initial locked position by the second clamping plate f13 within the groove where the side end fits into the second clamping plate f13. This allows the accumulator valve f of the equipment to be linked with the main control valve i. After the main control valve i is closed, the drain pipe d is instantly closed by accumulating force. This ensures that the turbine e can operate normally before the drain pipe d is closed. At the same time, it can better ensure that the accumulator valve f has enough force to close the drain pipe d. This avoids the inconvenience of the drain pipe d not closing synchronously with the main control valve i because the driving force of the turbine e decreases as the drain pipe d is closed too much, while the pressure to close the drain pipe d increases instead.

[0056] In the description of this invention, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
