Description

Technical Field

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

[0002] Flow regulating valves, also known as self-operated flow control valves, are intuitive and simple flow regulation and control devices. In pipeline networks, flow regulating valves allow for direct flow rate settings based on design specifications. Under water pressure, the valve automatically eliminates flow deviations caused by residual head and pressure fluctuations in the pipeline, maintaining the set flow rate regardless of system pressure changes. These functions enable one-step flow regulation, transforming network adjustment into simple flow distribution and effectively resolving hydraulic imbalances in the pipeline network. Existing flow regulating valves primarily regulate flow by controlling the valve core opening amplitude through an actuator. This control method, due to the small valve core opening amplitude, results in a limited controllable range of water output, failing to meet the demands for more precise flow rate regulation. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that cannot meet the needs of more precise water flow regulation, and to propose a water flow regulating valve.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A water flow regulating valve is designed, including a valve body with an inner cavity. An outlet pipe communicating with the inner cavity is provided on the valve body. A first through hole and a second through hole are respectively formed on the top and bottom surfaces of the valve body. The first and second through holes are coaxially arranged. An inlet pipe is coaxially fixed at the second through hole, and the inner end of the inlet pipe is sealed. Several outlet holes are formed circumferentially on the inlet pipe in the inner cavity. A movable pipe is coaxially fixed in the first through hole, and the inner end of the movable pipe extends into the inner cavity and is sleeved on the inlet pipe. The movable pipe is driven by a driving mechanism, which drives the movable pipe to reciprocate coaxially along its central axis.

[0006] Preferably, a sleeve is coaxially fitted on the movable tube outside the inner cavity, and the sleeve is fixedly connected to the valve body.

[0007] Preferably, a rubber sealing sleeve is coaxially fixed inside the sleeve.

[0008] Preferably, the driving mechanism includes a screw and a connecting plate. The connecting plate is coaxially fixed to the outer end of the movable pipe. The screw is coaxially threaded through the connecting plate, and the inner end of the screw is coaxially and rotatably connected to the inner end of the water inlet pipe.

[0009] Preferably, a plurality of unclogging wires are fixed circumferentially at the inner end of the movable tube, and the unclogging wires are arranged corresponding to the water outlet holes.

[0010] Preferably, the unclogging wire is arc-shaped, and the concave surface of the unclogging wire faces the movable tube.

[0011] Preferably, the unclogging wire is made of steel wire.

[0012] The water flow regulating valve proposed in this utility model has the following advantages:

[0013] By controlling the vertical movement distance of the movable tube, the number of water outlet holes on the inlet pipe blocked by the movable tube can be controlled, thereby controlling the water flow through the outlet holes and adjusting the water flow of the outlet pipe to achieve more precise flow control.

[0014] By installing several unclogging threads at the bottom of the movable pipe, the unclogging threads can be inserted into the water outlet during the movement of the movable pipe to scrape off the impurities attached to the water outlet, thereby ensuring the smooth flow of the water outlet.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figure 1-2 A water flow regulating valve includes a valve body 1 with an inner cavity. An outlet pipe 2 communicating with the inner cavity is provided on the valve body 1. A first through hole 10 and a second through hole 99 are respectively provided through the top and bottom surfaces of the valve body 1. The first through hole 10 and the second through hole 9 are coaxially arranged. An inlet pipe 3 is coaxially fixed at the second through hole 9. The inner end of the inlet pipe 3 is sealed. Several outlet holes 4 are circumferentially provided through the inlet pipe 3 in the inner cavity. A movable pipe 6 is coaxially fixed in the first through hole 10. The inner end of the movable pipe 6 extends into the inner cavity and is sleeved on the inlet pipe 3. The movable pipe 6 is driven by a driving mechanism, which drives the movable pipe 6 to reciprocate along its central axis.

[0024] A sleeve 5 is coaxially fitted onto the movable tube 6 outside the inner cavity, and the sleeve 5 is fixedly connected to the valve body 1. A rubber sealing sleeve is coaxially fixed inside the sleeve 5. The sleeve 5 protects the movable tube 6 entering and exiting the inner cavity of the valve body 1 to prevent particulate matter from adhering to its surface and causing wear during sliding. A keyway is formed on the inner wall of the first through hole 10 and the sleeve 5. The keyway is set parallel to the water inlet pipe 3. A spline is provided on the movable tube 6 that is embedded in the keyway. Through the cooperation of the spline and the keyway, the movable tube 6 can only slide axially and cannot rotate.

[0025] The drive mechanism includes a screw 7 and a connecting plate. The connecting plate is coaxially fixed to the outer end of the movable tube 6. The screw 7 is coaxially threaded through the connecting plate, and its inner end is rotatably connected to the inner end of the water inlet pipe 3. Several vent holes are formed through the connecting plate to connect the inner cavity of the movable tube 6 with the outside air, ensuring that the movement of the movable tube 6 is not obstructed by air when the screw 7 is running. A nut can be installed on the screw 7, allowing manual turning of the screw 7 to drive the connecting plate and move the movable tube 6. Alternatively, the screw 7 can be connected to a micro motor, and the motor can be controlled to drive the screw 7 to rotate. By using the screw 7 to drive the movable tube 6, the thread on the screw 7 can be used to achieve precise control of the movement distance of the movable tube 6, thereby better controlling the flow rate.

[0026] Example 2: Refer to Figure 3-6In another preferred embodiment of this utility model, the difference from Embodiment 1 is that a plurality of unclogging wires 8 are fixed circumferentially at the inner end of the movable tube 6, and the unclogging wires 8 are correspondingly arranged with the water outlet 4. The unclogging wires 8 are arc-shaped, and the concave surface of the unclogging wires 8 faces the movable tube 6. The unclogging wires 8 are made of steel wire. Steel wire has good toughness and fatigue strength.

[0027] When water flows out of the inlet pipe 3 through the outlet holes 4, due to the large number of outlet holes 4 and their small diameter, impurities in the water easily adhere to them. Over time, the inner diameter of the outlet holes 4 will decrease, resulting in a reduction in water flow. To address this, a drain cleaner 8 is provided. This drain cleaner 8 has good flexibility. When the movable pipe 6 moves the drain cleaner 8 to the outlet hole 4, the drain cleaner 8 will extend and insert into the outlet hole 4. As the movable pipe 6 continues to move the drain cleaner 8 upwards, the drain cleaner 8 will move out of the outlet hole 4 and bend due to the pressure from the outer wall of the movable pipe 6. To prevent the drain cleaner 8 from being squeezed by the movable pipe 6 and the inner wall of the cavity, a certain distance is left between the inner end of the movable pipe 6 and the inner wall of the cavity, so that the drain cleaner 8 will not be squeezed when the movable pipe 6 moves to its lowest point.

[0028] This invention uses an operating drive mechanism to drive the movable tube 6 to move axially back and forth, allowing the movable tube 6 to block the water outlet 4 on the inlet pipe 3. By controlling the vertical movement distance of the movable tube 6, the number of water outlet 4 blocked by the movable tube 6 on the inlet pipe 3 can be controlled, thereby controlling the water flow rate through the water outlet 4 of the inlet pipe 3, and thus adjusting the water flow rate of the outlet pipe 2; simultaneously, as shown in the attached... Figure 5-6 As shown, by setting several unclogging wires 8 at the bottom of the movable pipe 6, the unclogging wires 8 can extend into the water outlet 4 during the movement of the movable pipe 6, scraping off the impurities attached to the water outlet 4, thereby ensuring the smooth flow of the water outlet pipe 2.

[0029] 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.
