Description

Technical Field

[0001] This invention belongs to the field of valve technology, and specifically discloses an electrically controlled valve and a smart water meter. Background Technology

[0002] In water supply systems and industrial fluid transport, water meters and electrically controlled valves, as key equipment for flow measurement and control, are widely used in residential water supply, industrial circulating water, and agricultural irrigation. Traditional water meters or electrically controlled valves typically employ simple ball valves, butterfly valves, or gate valve structures, controlling the flow of fluid through the raising or lowering or rotating of the valve core. However, in actual long-term use, existing technologies have the following shortcomings: 1. Problems with contaminant deposition and sealing failure: Fluids often contain impurities such as mud, rust, and microbial slime. These impurities easily deposit and scale at the bottom, inclined walls, or sealing contact surfaces of the valve. When the valve is closed, if particulate matter is attached to the sealing surface (such as the contact area between the valve core and the valve seat), it will lead to poor sealing and leakage. At the same time, the deposits will also affect the detection accuracy of the flow sensor, causing measurement deviations.

[0003] 2. The negative impact of water hammer effect is not utilized: When a valve is closed rapidly, the fluid in the pipeline will generate an instantaneous pressure shock due to inertia (water hammer effect). In traditional designs, this shock often damages the pipeline and valve, requiring the installation of an additional water hammer eliminator. However, existing technology lacks a way to convert water hammer energy into the power to clean internal components, and fails to utilize water hammer oscillation to remove dirt adhering to the inclined plate or cavity wall.

[0004] 3. Poor durability of the sealing structure: Common sealing methods often use a single rubber gasket, which is prone to aging, deformation, or loss of elasticity after long-term pressure. Furthermore, the lack of auxiliary compression and compensation mechanisms leads to a decline in sealing performance after repeated opening and closing. In addition, if the contact surface between the valve core and the sealing ring is flat or conical, impurities can easily remain, further accelerating seal failure.

[0005] 4. Lack of intelligent detection and self-cleaning collaborative design: Although some existing smart water meters can detect flow, the sealing and isolation between the actuator (such as electric push rod) and the fluid chamber is not perfect, which can easily cause electronic components to be damaged by moisture. At the same time, the structural design of the internal partition and guide plate of the valve body is simple and does not take into account the functions of flow guidance, anti-clogging and self-cleaning, which makes frequent manual maintenance required after long-term operation.

[0006] To address the aforementioned issues, a novel water meter structure is needed that can effectively utilize the fluid's own hydraulic characteristics (such as water hammer oscillation and impact flow guidance) to achieve self-cleaning of internal components, and possess high sealing reliability and intelligent flow monitoring functions, thereby extending equipment lifespan, reducing maintenance costs, and improving metering and control accuracy. Summary of the Invention

[0007] In view of this, the purpose of this invention is to provide an electrically controlled valve and a smart water meter to solve the problems mentioned above.

[0008] To achieve the above objectives, the present invention provides an electrically controlled valve and a smart water meter, comprising a spherical cavity and a first connecting pipe fixed on the left side of the spherical cavity and a second connecting pipe fixed on the right side of the spherical cavity. A smart meter body is distributed above the spherical cavity. A dividing member is fixed in the middle of the inner cavity of the spherical cavity. The dividing member divides the inner cavity of the spherical cavity into an upper inner cavity and a lower inner cavity. The upper inner cavity is connected to the inner cavity of the second connecting pipe, and the lower inner cavity is connected to the inner cavity of the first connecting pipe. The dividing component includes a third inclined plate fixed in the inner cavity of the spherical cavity. A second inclined plate is fixed to the left side of the third inclined plate at an upward angle, and a first inclined plate is fixed to the right side of the third inclined plate at a downward angle. The second and first inclined plates are integrally fixed with the third inclined plate. The second, first, and third inclined plates are all made of a material with good elasticity. A liquid outlet pipe is integrally fixed to the middle of the third inclined plate, and the liquid outlet pipe is integrally fixed to the third inclined plate. The lower part of the third inclined plate is fixedly connected to the first inclined plate. An upper pipe is fixed above the spherical cavity, and an opening and closing structure is fixed on the upper pipe. A plug is slidably disposed inside the upper pipe. An abutment block is connected to the lower part of the plug, and the upper part of the plug is connected to the opening and closing structure. The opening and closing structure is used to drive the plug to move in the upper part of the spherical cavity. The abutment block is used to seal the upper end of the liquid outlet pipe.

[0009] In the above technical solution, the abutment block is further defined as a hemispherical structure, and multiple insertion tubes are fixed on the upper part of the abutment block. An insertion hole is provided on the plug above the insertion tube. The insertion tube is inserted into the insertion hole, thereby limiting the installation position of the abutment block. An installation bolt passes through the plug, and the lower part of the installation bolt is threadedly connected to the insertion tube, thereby fixing the insertion tube to the plug.

[0010] In the above technical solution, the side of the abutment block facing the outlet pipe has a smooth surface structure, and the side of the abutment block facing the outlet pipe is coated with a hydrophobic coating to prevent the sewage discharged by the valve from adhering to the abutment block. The outer edge of the upper end of the outlet pipe is provided with a bevel, and the bevel abuts against the abutment block to achieve a seal between the abutment block and the outlet end of the outlet pipe.

[0011] In the above technical solution, the upper part of the liquid outlet pipe is provided with an annular groove, the inner wall of the annular groove cavity is embedded with a compression rubber ring, the inside of the annular groove is embedded with a sealing rubber ring, and the compression rubber ring abuts against the sealing rubber ring to strengthen the fixing strength of the sealing rubber ring and the liquid outlet pipe.

[0012] In the above technical solution, the top surface of the sealing ring is higher than the top surface of the inclined plane, both the sealing ring and the compression ring are elastic, and the top surface of the sealing ring abuts against the abutting block to enhance the sealing effect of the abutting block on the liquid outlet pipe.

[0013] In the above technical solution, a water flow sensor is further fixed on the second connecting pipe. The water flow sensor is used to detect the liquid flow inside the second connecting pipe. The water flow sensor is connected to the smart meter body and is used to transmit the water flow information inside the second connecting pipe to the smart meter body, thereby realizing the detection of the water flow information of the valve during the cleaning of the smart meter body.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, when the abutment block seals the discharge end of the outlet pipe, the water discharged from the first connector cannot pass through the outlet pipe into the second connector. At this time, a water hammer effect occurs in the lower cavity of the spherical cavity. The impact force generated by the water is transmitted to the first, second, and third inclined plates, causing the dirt attached to these inclined plates to be shaken and quickly separated with the water flow, thereby keeping the surfaces of the first, second, and third inclined plates clean. This design converts the traditionally harmful water hammer energy into cleaning power, avoiding blockages and metering errors caused by long-term accumulation of impurities.

[0015] 2. In this invention, the upper end of the outlet pipe is provided with a sealing ring and a compression ring, with the top surface of the sealing ring higher than the inclined surface. When the abutment block compresses the sealing ring, the sealing ring is compressed and deformed, making it fit tightly against the abutment block; simultaneously, the portion of the sealing ring embedded in the outlet pipe expands and applies pressure to the compression ring, which in turn uses its own elastic restoring force to compress the sealing ring in the opposite direction, thereby enhancing the connection strength between the sealing ring and the outlet pipe. This structure solves the problem of sealing failure caused by the easy aging and deformation of a single rubber gasket, extending the sealing life.

[0016] 3. The abutment block in this invention has a hemispherical structure, and an inclined surface is formed on the outer edge of the upper end of the liquid outlet pipe. As the abutment block approaches the liquid outlet pipe, the water discharged from the pipe impacts the abutment block, and the hemispherical surface guides the water onto the first, second, and third inclined plates, simultaneously rinsing the sealing ring and the inclined surface, effectively preventing contaminants from adhering to the sealing contact surface. This ensures that the abutment block remains clean when it is subsequently bonded to the sealing ring, solving the problem of leakage caused by impurities adhering to the sealing surface.

[0017] 4. A water flow sensor is fixed to the second connecting pipe of this invention, which can detect the liquid flow rate in real time and transmit the information to the smart meter body. The smart meter body has a built-in analysis program and displays the flow data, realizing accurate measurement and intelligent monitoring. At the same time, a sealing element is fixed inside the sealing tube to seal the gap between the output end of the electric push rod and the sealing tube, preventing water from the upper connecting pipe from entering the sealing tube and the electric push rod, thus protecting the electronic components from moisture damage. This design takes into account the reliable isolation between intelligent detection and the actuator, solving the problems of traditional smart water meters being susceptible to moisture and requiring frequent maintenance.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] Example 1: Please refer to Figures 1-8 As shown, the present invention provides a technical solution: The present invention is an electrically controlled valve and a smart water meter, including a spherical cavity 11 and a first connecting pipe 12 fixed on the left side of the spherical cavity 11 and a second connecting pipe 13 fixed on the right side of the spherical cavity 11. A smart meter body 2 is distributed above the spherical cavity 11. A dividing member is fixed in the middle of the inner cavity of the spherical cavity 11, and the dividing member divides the inner cavity of the spherical cavity 11 into an upper inner cavity and a lower inner cavity. The dividing component includes a third inclined plate 43 fixed in the inner cavity of the spherical cavity 11. A second inclined plate 42 is fixed to the left side of the third inclined plate 43 at an upward inclination, and a first inclined plate 4 is fixed to the right side of the third inclined plate 43 at a downward inclination. The second inclined plate 42 and the first inclined plate 4 are integrally fixed with the third inclined plate 43. The third inclined plate 43 has an integrally fixed liquid outlet pipe 41 in the middle. The upper pipe 1 is fixed above the spherical cavity 11. The upper pipe 1 has an opening and closing structure. The upper pipe 1 has a plug 31 slidably installed inside. The lower part of the plug 31 is connected to an abutment block 33. The upper part of the plug 31 is connected to the opening and closing structure. The abutment block 33 is used to seal the upper end of the liquid outlet pipe 41.

[0023] The abutment block 33 has a hemispherical structure. Multiple insertion tubes 34 are fixed on the upper part of the abutment block 33. An insertion hole 35 is opened on the plug 31 above the insertion tube 34. The insertion tube 34 is inserted into the insertion hole 35. An installation bolt 32 passes through the plug 31. The lower part of the installation bolt 32 is threadedly connected to the insertion tube 34.

[0024] The side of the abutment block 33 facing the liquid outlet pipe 41 has a smooth surface structure, and the outer edge of the upper end of the liquid outlet pipe 41 is provided with a bevel 45, which abuts against the abutment block 33.

[0025] An annular groove is provided at the upper part of the outlet pipe 41. A compression ring 46 is embedded in the inner wall of the annular groove cavity, and a sealing ring 44 is embedded inside the annular groove. The compression ring 46 abuts against the sealing ring 44.

[0026] The top surface of the sealing ring 44 is higher than the top surface of the inclined surface 45. Both the sealing ring 44 and the compression ring 46 are elastic. The top surface of the sealing ring 44 abuts against the abutting block 33.

[0027] A water flow sensor 21 is fixed on the second pipe 13. The water flow sensor 21 is used to detect the liquid flow inside the second pipe 13. The water flow sensor 21 is connected to the smart meter body 2.

[0028] A lower connecting pipe 14 is fixed to the bottom of the spherical cavity 11. The inner cavity of the lower connecting pipe 14 is connected to the inner cavity of the spherical cavity 11. A sealing bolt 18 is fixed on the lower connecting pipe 14. In actual use, the outer end of the first connector 12 is connected to the water supply pipe in advance, and the outer end of the second connector 13 is connected to the drainage pipe. When the water supplied by the water supply pipe needs to be transported to the inside of the drainage pipe through the electric control valve, the electric push rod 17 is turned off. At this time, the output end of the electric push rod 17 drives the abutment block 33 to separate from the sealing ring 44, so that the plug 31 can drive the abutment block 33 to be stored inside the upper connector 1, so that the abutment block 33 does not block the discharge port of the liquid outlet pipe 41. This allows the water discharged from the liquid outlet pipe 41 to enter the inside of the second connector 13, and then the second connector 13 transports the water to the inside of the drainage pipe. When the second connector 13 drives the water to be transported to the inside of the drainage pipe, the water flow sensor 21 can detect the flow rate of the water inside the second connector 13 in real time, and then transmit the detection information to the inside of the smart meter body 2. The smart meter body 2 has an analysis program installed inside, which can analyze the information transmitted by the water flow sensor 21 in real time, and then display the information through the smart meter body 2, so as to facilitate the display of the water flow rate of the second connector 13 in the smart meter body 2. When the water supplied by the first connector 12 passes through the spherical cavity 11 and enters the interior of the second connector 13, the seal 16 can seal the gap between the output end of the electric push rod 17 and the sealing tube 15, thereby preventing the water inside the upper connector 1 from entering the interior of the sealing tube 15. When the staff wants to block the discharge end of the liquid outlet pipe 41, the output end of the electric push rod 17 can drive the plug 31 to move down through the connector 3, thereby causing the plug 31 to drive the abutment block 33 to abut against the discharge end of the liquid outlet pipe 41. After the abutment block 33 abuts against the discharge end of the liquid outlet pipe 41, the abutment block 33 can squeeze the upper end of the sealing ring 44, thereby deforming the contact surface between the sealing ring 44 and the abutment block 33, so that the sealing ring 44 and the abutment block 33 fit tightly, improving the sealing effect of the abutment block 33 on the liquid outlet pipe 41. When the abutment block 33 presses against the sealing ring 44, the height of the sealing ring 44 will be compressed, thereby causing the part of the sealing ring 44 embedded in the liquid outlet pipe 41 to expand. This will also cause the sealing ring 44 to press against the extrusion ring 46, so that the extrusion ring 46 can press against the sealing ring 44 through its own restoring force, thereby improving the connection strength between the sealing ring 44 and the liquid outlet pipe 41. When the abutment block 33 blocks the discharge end of the outlet pipe 41, the water discharged from the first connector 12 cannot pass through the outlet pipe 41 and flow into the interior of the second connector 13. At this time, a water hammer effect will occur in the lower cavity of the spherical cavity 11. This allows the impact force generated by the water to be transmitted to the first inclined plate 4, the second inclined plate 42, and the third inclined plate 43. As a result, the dirt on the first inclined plate 4, the second inclined plate 42, and the third inclined plate 43 is shaken. The dirt after being shaken can be quickly separated under the action of the water flow, thereby keeping the first inclined plate 4, the second inclined plate 42, and the third inclined plate 43 clean.

[0029] Example 2: Please refer to Figures 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, when the water impacts the abutment block 33, the abutment block 33 can guide the water discharged from the outlet pipe 41, thereby allowing the water discharged from the outlet pipe 41 to splash onto the first inclined plate 4, the second inclined plate 42, and the third inclined plate 43. At the same time, the water discharged from the outlet pipe 41 can also impact the sealing ring 44 and the inclined surface 45, thereby preventing dirt from adhering to the sealing ring 44 and the inclined surface 45, facilitating the subsequent contact between the sealing ring 44 and the inclined surface 45 and the abutment block 33, and achieving the sealing of the outlet end of the outlet pipe 41 by the abutment block 33.

[0030] The opening and closing structure includes a sealing tube 15 fixed to the upper end of the upper pipe 1, a sealing element 16 fixed inside the sealing tube 15, and an electric push rod 17 fixed on the sealing tube 15. The output end of the electric push rod 17 passes through the sealing element 16 and is inserted into the interior of the upper pipe 1.

[0031] The smart watch body 2 is fixed on the sealing tube 15. The electric push rod 17 is inserted into the upper tube 1 and a connector 3 is fixed at one end. The connector 3 is fixed on the upper part of the plug 31. As the contact block 33 approaches the outlet pipe 41, the water discharged from the outlet pipe 41 impacts the contact block 33. Since the contact block 33 has a hemispherical structure, after the water impacts the contact block 33, the contact block 33 can guide the water discharged from the outlet pipe 41, thereby allowing the water discharged from the outlet pipe 41 to fall onto the first inclined plate 4, the second inclined plate 42, and the third inclined plate 43. At the same time, the water discharged from the outlet pipe 41 can also impact the sealing ring 44 and the inclined surface 45, thereby preventing dirt from adhering to the sealing ring 44 and the inclined surface 45, making it easier for the sealing ring 44 and the inclined surface 45 to fit with the contact block 33 in the future, so as to seal the outlet end of the outlet pipe 41 with the contact block 33. The third inclined plate 43 tilts downwards near the first inclined plate 4. When water washes the first inclined plate 4, the second inclined plate 42, and the third inclined plate 43, the dirt on the second inclined plate 42 and the third inclined plate 43 can flow into the interior of the second connecting pipe 13 under the guidance of the first inclined plate 4. This allows the dirt on the first inclined plate 4, the second inclined plate 42, and the third inclined plate 43 to be quickly discharged with the water flow, thus keeping the first inclined plate 4, the second inclined plate 42, and the third inclined plate 43 clean and preventing them from being corroded by dirt. This ensures the service life of the electrically controlled valve, reduces the probability of maintenance of the electrically controlled valve, and lowers the maintenance cost of the electrically controlled valve.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
