Description

Technical Field

[0001] This application relates to the field of water pumps, and more particularly to a water pump with flow regulation function. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] Currently, Chinese utility model patent CN219263201U discloses a flow regulation structure for a water pump valve, including a cylindrical valve shell with a hollow valve cavity. A cylindrical valve plate is located within the valve cavity. A rubber ring gasket surrounds the valve plate on the inner wall of the valve shell, and the valve plate is embedded within the rubber ring gasket. A vertical through-shaft extends through the valve plate vertically. A through hole is formed at both the top and bottom of the rubber ring gasket. The top of the valve shell has a through hole aligned with the through hole, and the bottom has a receiving groove. Through holes are formed at both ends of the through-shaft. The top of the through-shaft extends into the through hole and is connected to a rotating shaft. The top of the rotating shaft protrudes from the valve shell and is connected to an adjusting shaft. A rotation damper is embedded outside the protruding section of the rotating shaft. A rotating block is connected to the bottom of the through-shaft and screwed into the receiving groove. This utility model allows for flow regulation through the opening and closing of the valve plate.

[0004] The flow regulation structure needs to be installed on the water pump. When the flow rate of the water pump needs to be adjusted, the operator adjusts the flow rate into the water pump by changing the angle of the valve plate. However, long-term adjustment of the valve plate can easily cause the rubber ring gasket to rub against the valve body. The rubber ring gasket wears out quickly, resulting in a short service life of the water pump's regulation function. Utility Model Content

[0005] In order to extend the service life of the flow regulation structure of the water pump, this application provides a water pump with flow regulation function.

[0006] This application provides a water pump with flow regulation function, which adopts the following technical solution:

[0007] A water pump with flow regulation function includes a pump body, a connecting pipe, and an regulating component. The connecting pipe is connected to the inlet of the pump body. The regulating component is located inside the connecting pipe and includes several regulating plates, a mounting frame, and a driving component. The mounting frame is disposed inside the connecting pipe. The several regulating plates are circumferentially distributed along the axis of the connecting pipe. Adjacent regulating plates abut against each other, and the several regulating plates form a channel for water flow. The regulating plates are slidably connected to the mounting frame along an axis close to or away from the connecting pipe. The driving component is used to drive the several regulating plates to move simultaneously.

[0008] By adopting the above technical solution, when the water pump flow rate needs to be adjusted, the operator simultaneously moves the regulating plate using the drive component. Since adjacent regulating plates abut against each other and slide along the axis towards or away from the connecting plate, when the regulating plate moves away from the connecting pipe axis, the flow channels formed by several regulating plates gradually increase, increasing the flow rate through the connecting pipe. Conversely, when the regulating plate moves towards the connecting pipe axis, the flow channels formed by several regulating plates gradually decrease until they are closed. Because the direction of movement of the regulating plate is perpendicular to the direction of water flow, the regulating plate will not rub against the inner wall of the connecting pipe during flow adjustment, extending the lifespan of the flow regulation function. Furthermore, the regulating plate will not rotate due to the impact of the water flow, improving the reliability of flow regulation.

[0009] Optionally, the driving component includes a driving ring, which is coaxially arranged with the connecting pipe. An adjusting block is provided on the adjusting plate, and a sliding groove is provided on the driving ring. The extending direction of the sliding groove forms an angle with the sliding direction of the adjusting plate on the mounting bracket, and the adjusting block is located in the sliding groove.

[0010] By adopting the above technical solution, when the operator needs to adjust the water pump flow rate simultaneously, the operator can rotate the drive ring. The drive ring rotates relative to the mounting frame. Since the adjustment block on the adjustment plate is located in the sliding groove, the position of the adjustment block in the sliding groove changes. Furthermore, the sliding groove is not parallel to the sliding direction of the adjustment plate on the mounting frame, causing the adjustment plate to slide relative to the mounting frame. Several adjustment plates change their positions simultaneously, resulting in a change in the cross-sectional area of ​​the water supply flow channel formed by the several adjustment plates, thus realizing the flow rate adjustment. The drive component has a simple structure and is easy to operate.

[0011] Optionally, the driving component further includes a worm gear and a worm. The worm gear is coaxially arranged with the driving ring and is disposed on the driving ring. The worm is rotatably connected to the connecting pipe and meshes with the worm gear. One end of the worm extends out of the connecting pipe.

[0012] By adopting the above technical solution, when the operator needs to adjust the water pump flow rate, the operator rotates the worm gear, which drives the worm wheel to rotate, which in turn drives the drive ring to rotate. The drive ring rotates relative to the connecting pipe and relative to the mounting bracket. The angle between the sliding groove and the sliding direction of the adjusting plate on the mounting bracket changes, thus changing the position of the adjusting plate relative to the drive ring. The cross-sectional area of ​​the water supply channel formed by several adjusting plates changes, thereby achieving water pump flow rate adjustment. The worm gear has a self-locking effect, reducing accidental changes in the position of the adjusting plate caused by operator touch. The worm gear has high adjustment accuracy, achieving precise flow rate adjustment.

[0013] Optionally, the drive ring is provided with an exposed block, and the connecting pipe is provided with a mating groove, through which the exposed block protrudes.

[0014] By adopting the above technical solution, since the adjustment components are all located inside the connecting pipe, it is difficult for the staff to know the changes in the cross-section of the water supply flow channel formed by several adjustment plates. The exposed block is set on the drive ring, and the staff can know the movement distance of the adjustment plate by observing the movement distance of the exposed block in the mating groove.

[0015] Optionally, the connecting pipe is provided with scale lines for displaying the cross-sectional size of the water supply flow channel formed by the plurality of adjusting plates.

[0016] By adopting the above technical solution, the operator drives the drive ring to rotate via a worm gear. The rotation of the drive ring causes the position of several adjusting plates to be adjusted, which in turn changes the cross-sectional area of ​​the water supply channel formed by the adjusting plates. The exposed block on the drive ring allows the operator to easily see the change in the cross-sectional area of ​​the water supply channel formed by the adjusting plates, and the scale lines allow the operator to make precise adjustments to the drive ring, making the operation more convenient.

[0017] Optionally, a flange is provided on the connecting pipe, and the flange is connected to the pump body by bolts.

[0018] By adopting the above technical solution, the flange is used to connect the connecting pipe to the pump body. The flange improves the connection strength between the connecting pipe and the pump body, and also improves the sealing performance between the connecting pipe and the pump body.

[0019] Optionally, a bracket is provided on the connecting pipe, and a mounting frame is provided on the pump body, the bracket being used to engage with the mounting block.

[0020] By adopting the above technical solution, when installing the connecting pipe on the pump body, the operator can connect the connecting pipe to the pump body by snapping the bracket onto the mounting frame, which allows the operator to operate independently and improves the convenience of installation.

[0021] Optionally, the mounting frame is provided with fixing bolts, the tail of which is threaded to the mounting frame and abuts against the bracket.

[0022] By adopting the above technical solution, the fixing bolts further improve the reliability of the connection between the mounting block and the bracket.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The driving component moves several adjusting plates to move closer to or further away from the axis of the connecting pipe at the same time. The cross-section of the water supply channel formed by the several adjusting plates changes, thereby realizing the flow regulation of the water pump. Since the moving direction of the adjusting plates is perpendicular to the flow direction of the water, there is no friction between the edge of the adjusting plate and the connecting pipe. The adjusting plates will not rotate due to the impact of the water flow, making the adjusting component more reliable.

[0025] 2. The exposed block slides within the mating groove, making it easy for staff to observe the rotation angle of the drive ring and to control the cross-sectional area of ​​the channel for water supply flow formed by the regulating plate;

[0026] 3. The bracket and mounting frame work together to facilitate the connection and installation of the connecting pipes and pump body by a single worker. Attached Figure Description

[0035] refer to Figure 3 and Figure 4The driving component 33 includes a driving ring 331, a worm gear 332, and a worm 333. The driving ring 331 is located on the side of the adjusting plate 31 facing away from the mounting bracket 32. The driving ring 331 is coaxially arranged with the operating tube 22 and is rotatably connected to the receiving cavity 221. Six sliding grooves 334 are formed on the end face of the driving ring 331 facing the adjusting plate 31. The extension direction of the six sliding grooves 334 forms a virtual regular hexagon. The six sliding grooves 334 correspond to six adjusting plates 31. Adjusting blocks 36 are fixedly arranged on the adjusting plates 31 and are slidably connected to the corresponding adjusting plates 31. Inside the sliding groove 334, the extending direction of the limiting groove 321 forms an angle with the extending direction of the sliding groove 334 corresponding to the same adjusting plate 31.

[0037] The implementation principle of a water pump with flow regulation function in this application embodiment is as follows: when the water pump needs to add flow regulation function, the operator can connect the connecting pipe 2 to the pump body 1 through the flange 211. With the cooperation of the bracket 4 and the mounting frame 5, only one operator is needed to complete the installation of the connecting pipe 2.

[0038] When the flow rate needs to be adjusted locally, the operator can rotate the worm gear 333, which drives the worm wheel 332 to rotate. The worm wheel 332 drives the drive ring 331 to rotate. The drive ring 331 rotates relative to the mounting plate. The sliding groove 334 on the drive ring 331 and the limiting groove 321 on the mounting plate simultaneously drive the adjusting plate 31 to move. Several adjusting plates 31 abut against each other, so that the cross-section of the water supply flow channel formed by several adjusting plates 31 changes. The operator can know the degree of adjustment of the adjusting plate 31 by the relative position of the exposed block 7 and the scale line 9.
