Description

Technical Field

[0001] This invention relates to the field of valve technology, and in particular to a water supply valve with flow detection. Background Technology

[0002] Water supply valves are devices used to control water flow and are commonly found in piping systems in homes, industrial, and commercial buildings. They control water flow by opening or closing, which is crucial for maintenance and shutting off water supply in emergencies. To accurately control water flow, modern water supply valves are equipped with flow detection systems. Common flow detection systems use a turbine and a corresponding speed sensor. When water passes through the turbine, the fluid exerts a force on the turbine blades, causing the turbine to rotate. The speed sensor detects the turbine's rotational speed, and by calculating the number of pulses received per unit time, the fluid flow rate can be accurately calculated.

[0003] If a water supply valve is not designed or used properly, it may freeze in low temperatures, making it unable to open or close normally. This is especially true when the valve is closed, as a large amount of water will remain inside. If the water freezes and expands, it can damage the valve cavity structure and make the valve difficult to open.

[0004] Therefore, to address the above problems, a structure can be designed to remove a certain amount of water from the valve chamber when the water supply valve is closed, and a turbine-type flow detection system can be used to reduce the possibility of water freezing in the valve chamber. Summary of the Invention

[0005] To overcome the problem that when the water supply valve is closed, the water inside will freeze when it encounters low temperatures, causing the valve to fail to open or close properly and easily damaging the valve cavity structure.

[0006] The technical solution of the present invention is as follows: a water supply valve with flow detection, comprising a valve body assembly and a control assembly movably connected to the valve body assembly, further comprising a flow detection assembly installed inside the valve body assembly, an inflation assembly installed on the movable end of the valve body assembly, and an air bladder installed inside the valve body assembly. The inflation assembly is connected to the air bladder, and gas can flow between the inflation assembly and the air bladder when the control assembly moves. The valve body assembly includes a valve cavity, an inlet and an outlet disposed on the valve cavity. The control assembly is used to open or close the valve cavity. When the control assembly moves and closes the valve cavity, gas flows from the inflation assembly into the air bladder. A signal transceiver module is installed on the control assembly. A drive assembly is installed inside the valve body assembly. The flow detection assembly includes a turbine, which is installed on the output end of the drive assembly. A transmission assembly is installed on the turbine. A rotating assembly is movably connected to the control assembly. The input end of the rotating assembly is connected to the output end of the transmission assembly. When the control assembly moves, the signal transceiver module sends a signal to the drive assembly. The drive assembly is used to drive the turbine and the transmission assembly to rotate, and the transmission assembly is used to drive the rotating assembly to rotate.

[0007] Preferably, the control assembly includes a valve stem threaded onto the valve cavity and a valve head fixedly mounted on the valve stem. A channel is provided between the inlet and outlet. The valve stem is used to drive the valve head closer to or away from the channel. When the valve head enters the channel, the valve cavity is closed; when the valve head leaves the channel, the valve cavity is opened.

[0008] Preferably, the flow detection assembly includes a turbine movably connected in the outlet and a speed sensor mounted on the turbine, which is used to detect the turbine's rotational speed when the valve chamber is open.

[0009] Preferably, the control assembly also includes a pressure plate fixedly connected to the valve stem, and the inflation assembly includes an air cover mounted on the pressure plate and an air supply pipe connected at one end to the air cover, with the other end of the air supply pipe connected to the air bladder. Gas flows between the air cover and the air bladder through the air supply pipe. When the valve stem drives the valve head closer to the passage opening, gas flows from the air cover into the air bladder. When the valve stem drives the valve head away from the passage opening, gas flows from the air bladder into the air cover.

[0010] Preferably, the signal transceiver module includes a tension spring mounted on the pressure plate and a tension sensor mounted on the tension spring. The tension sensor is used to detect the tension value of the tension spring. When the valve head moves and enters the channel port, the tension sensor detects the tension value of the tension spring as F1 and sends a signal to the drive assembly.

[0011] Preferably, the drive assembly includes a motor mounted on the valve body assembly, with a turbine connected to the output end of the motor. When the tension sensor detects that the tension of the tension spring is F1, the motor drives the turbine to rotate at a preset speed. The transmission assembly includes a transmission rod fixedly connected at one end to the turbine and a transmission bevel gear mounted on the other end of the transmission rod. When the tension sensor detects that the tension of the tension spring is F1, the motor drives the transmission rod and the transmission bevel gear to rotate via the turbine.

[0012] Preferably, the control assembly also includes a hanger fixedly connected to the valve stem, and the rotating assembly includes a rotating ring movably connected to the hanger, an outer bevel gear ring disposed on the rotating ring, and a baffle plate fixedly connected to the rotating ring. The outer bevel gear ring meshes with a transmission bevel gear, and the transmission bevel gear drives the rotating ring to rotate through the outer bevel gear ring. The rotating ring accelerates the flow of the medium in the valve cavity through the baffle plate.

[0013] Preferably, a linkage component is movably connected to the control component, the input end of the linkage component is connected to the output end of the rotation component, and the rotation component is used to drive the linkage component to rotate. A vibration component is movably connected to the control component, the output end of the linkage component is connected to the input end of the vibration component, and the linkage component is used to drive the vibration component to move.

[0014] Preferably, the control component also includes a guide rod fixedly connected to the hanger, the rotating component also includes an inner flat gear ring set on the rotating ring, and the linkage component includes a linkage gear movably connected to the guide rod and a rolling frame fixedly installed on the linkage gear. The linkage gear meshes with the inner flat gear ring, the rotating ring drives the linkage gear to rotate through the inner flat gear ring, and the linkage gear drives the rolling frame to move on the vibration component.

[0015] Preferably, the vibration assembly includes a sleeve movably connected to the guide rod, a helical track installed inside the sleeve, a return spring installed on the sleeve, a connecting frame with one end installed on the sleeve, and a vibration ball fixedly installed on the other end of the connecting frame. One end of the return spring is connected to the sleeve, and the other end is connected to the hanger. The linkage gear drives the rolling frame to move along the helical track. When the rolling frame moves along the helical track, the sleeve moves along the guide rod. When the rolling frame moves from the top of the helical track to the bottom of the helical track, the sleeve drives the vibration ball away from the valve head through the connecting frame. When the rolling frame moves from the bottom of the helical track to the top of the helical track, the sleeve drives the vibration ball closer to the valve head through the connecting frame.

[0016] The beneficial effects of this invention are:

[0017] 1. By using the inflation component on the control component and the airbag in the valve chamber, the water in the valve chamber is expelled by the inflated airbag when the valve body component is closed, reducing the accumulation of water in the valve chamber. This effectively reduces the impact of water freezing in low-temperature environments on the normal opening and closing of the valve component, and also avoids damage to the valve body component due to the freezing expansion effect after a large amount of water freezes.

[0018] 2. By controlling the movement of the control components, the signal transceiver module automatically sends a signal to the drive component after the valve component is closed, controlling the turbine to rotate actively, and with the help of the transmission component, controlling the rotating component to disturb the water remaining in the valve chamber, further reducing the possibility of water freezing more easily due to its static state.

[0019] 3. By utilizing the mechanical transmission between the rotating component, the linkage component, and the vibration component, the valve head is continuously struck when the valve assembly is closed. The vibration of the structural components and the sound wave vibration cause the water accumulated around the dead corner of the valve head to fluctuate, further reducing the possibility of water freezing.

[0020] 4. With the valve assembly closed, power is transmitted through the turbine in the flow detection assembly, which can effectively prevent the turbine from freezing.

[0021] 5. During the opening and closing of the valve assembly, the connection or disconnection of the rotating assembly and the transmission assembly is controlled by the control assembly. This prevents the mechanical friction between the rotating assembly and the transmission assembly from affecting the normal rotation of the turbine when the valve assembly is open, thus preventing inaccurate flow detection.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Please see Figures 1-10This invention provides an embodiment of a water supply valve with flow detection, comprising a valve body assembly and a control assembly movably connected to the valve body assembly, and further comprising a flow detection assembly installed within the valve body assembly, an inflation assembly installed on the movable end of the valve body assembly, and an air bladder 401 installed within the valve body assembly. The inflation assembly is connected to the air bladder 401, and gas can flow between the inflation assembly and the air bladder 401 when the control assembly moves. The valve body assembly includes a valve cavity 101, an inlet 102 and an outlet 103 disposed on the valve cavity 101. The control assembly is used to open or close the valve cavity 101. When the control assembly moves and closes the valve cavity 101, gas flows from the inflation assembly into the air bladder 401. A signal transceiver module is installed on the control assembly, and a drive assembly is installed within the valve body assembly. The flow detection assembly includes a turbine 201, which is installed on the output end of the drive assembly. A transmission component is installed on the wheel 201, and a rotating component is movably connected to the control component. The input end of the rotating component is connected to the output end of the transmission component. When the control component moves, the signal transceiver module sends a signal to the drive component. The drive component is used to drive the turbine 201 and the transmission component to rotate, and the transmission component is used to drive the rotating component to rotate. When the user operates the control component to close the valve chamber 101, the control component applies a force to the inflation component, causing the gas in the inflation component to flow into the air bag 401. After the air bag 401 inflates, it squeezes the water out of the valve chamber 101. After the valve chamber 101 is completely closed, the signal transceiver module sends a signal to the drive component. At the same time, the input end of the rotating component is connected to the output end of the transmission component. The drive component controls the turbine 201 to rotate actively. The turbine 201 drives the rotating component to rotate with the help of the transmission component, disturbing the water accumulated in the valve chamber 101.

[0035] Please see Figures 1-3 and Figure 8In this embodiment, the control component includes a valve stem 104 threadedly connected to the valve chamber 101 and a valve head 105 fixedly mounted on the valve stem 104. A channel is provided between the inlet 102 and the outlet 103. The valve stem 104 is used to drive the valve head 105 closer to or further away from the channel. When the valve head 105 enters the channel, the valve chamber 101 is closed; when the valve head 105 leaves the channel, the valve chamber 101 is opened. The flow detection component includes a turbine 201 movably connected to the outlet 103 and a speed sensor 202 mounted on the turbine 201. When the valve chamber 101 is open, the speed sensor 202 is used to detect the rotational speed of the turbine 201. The user turns the valve stem 104 to control the valve head 105 to move upward away from the channel, opening the valve chamber 101. Water flows into the valve chamber 101 from the inlet 102. When the water passes through the turbine 201, the water exerts a force on the turbine blades, causing the turbine to... As turbine 201 rotates, the faster the water moves, the greater the force applied to turbine 201, and the higher the rotational speed of turbine 201. The rotational speed of turbine 201 is directly proportional to the average flow rate of water. By measuring the rotational speed of turbine 201 through speed sensor 202, the flow rate of water can be indirectly determined (turbine 201 is usually mounted on a precision bearing, and one or more detection devices, such as magnetoelectric sensors, are installed on its shaft). When turbine 201 rotates, pulse signals generated by turbine 201 can be detected. Each pulse represents a certain volume of fluid passing through. By calculating the number of pulses received per unit time, the flow rate of fluid can be accurately calculated. The flow rate is accurately measured by converting the kinetic energy of the fluid into the mechanical energy of turbine 201, and then converting it into an electrical signal through electronic means (it is worth noting that the above are all existing technologies, turbine 201 speed sensor 202).

[0036] Please see Figures 1-2 , Figure 4 and Figure 9In this embodiment, the control assembly further includes a pressure plate 106 fixedly connected to the valve stem 104. The inflation assembly includes an air cover 301 mounted on the pressure plate 106 and an air supply pipe 302 connected at one end to the air cover 301. The other end of the air supply pipe 302 is connected to the air bladder 401. Gas flows between the air cover 301 and the air bladder 401 through the air supply pipe 302. When the valve stem 104 drives the valve head 105 closer to the channel opening, gas flows from the air cover 301 into the air bladder 401. When the valve stem 104 drives the valve head 105 away from the channel opening, gas flows from the air bladder 401 into the air cover 301. The signal transceiver module includes a tension spring 501 mounted on the pressure plate 106 and a tension sensor 502 mounted on the tension spring 501. The tension sensor 502 is used to detect the tension value of the tension spring 501. When the valve head 105 moves and enters the channel opening, the tension sensor 502... 02 detects that the tension value of the tension spring 501 is F1 and sends a signal to the drive component. The user turns the valve stem 104, controls the valve head 105 to move downward into the channel opening, and closes the valve chamber 101. Water cannot flow into the valve chamber 101 from the inlet 102. During the movement of the valve stem 104 and the valve head 105, the pressure plate 106 generates pressure on the air cover 301 (which can adopt the accordion structure in the prior art), causing the gas in the air cover 301 to continuously flow into the air bag 401 through the air supply pipe 302. The air bag 401 expands and occupies a larger volume in the valve chamber 101, discharging the accumulated water from the valve chamber 101. After the valve head 105 is fully in the channel opening, the input end of the rotating component is connected to the output end of the transmission component, and the tension sensor 502 detects that the tension value of the tension spring 501 is F1 and sends a signal to the drive component.

[0037] Please see Figures 2-6 , Figure 8 and Figure 10In this embodiment, the drive assembly includes a motor 601 mounted on the valve body assembly, and a turbine 201 connected to the output end of the motor 601. When the tension sensor 502 detects that the tension value of the tension spring 501 is F1, the motor 601 drives the turbine 201 to rotate at a preset speed. The transmission assembly includes a transmission rod 701 fixedly connected at one end to the turbine 201 and a transmission bevel gear 702 mounted on the other end of the transmission rod 701. When the tension sensor 502 detects that the tension value of the tension spring 501 is F1, the motor 601 drives the transmission rod 701 and the transmission bevel gear 702 to rotate via the turbine 201. The control assembly also includes a hanger 107 fixedly connected to the valve stem 104, and the rotation assembly includes a rotating ring 801 movably connected to the hanger 107 and a rotating ring 801. The outer bevel gear ring 802 on 01 and the baffle plate 803 fixedly connected to the rotating ring 801 are connected. The outer bevel gear ring 802 meshes with the transmission bevel gear 702. The transmission bevel gear 702 drives the rotating ring 801 to rotate through the outer bevel gear ring 802. The rotating ring 801 accelerates the flow of the medium in the valve chamber 101 through the baffle plate 803. After receiving the signal from the tension sensor 502, the motor 601 starts automatically and controls the turbine 201, the transmission rod 701, and the transmission bevel gear 702 to rotate actively. The transmission bevel gear 702 transmits power to the rotating ring 801 through the outer bevel gear ring 802, causing the rotating ring 801 to rotate continuously. This causes the baffle plate 803 to disturb the water accumulated in the valve chamber 101 (in this technical solution, the water around the valve head 105). The continuous flow of water makes it less likely to freeze.

[0038] Please see Figure 2 , Figures 4-7 and Figure 10In this embodiment, a linkage component is movably connected to the control component. The input end of the linkage component is connected to the output end of the rotation component. The rotation component is used to drive the linkage component to rotate. A vibration component is movably connected to the control component. The output end of the linkage component is connected to the input end of the vibration component. The linkage component is used to drive the vibration component to move. The control component also includes a guide rod 108 fixedly connected to the hanger 107. The rotation component also includes an inner flat gear ring 804 disposed on the rotating ring 801. The linkage component includes a linkage gear 901 movably connected to the guide rod 108 and a rolling frame 902 fixedly installed on the linkage gear 901. The linkage gear 901 meshes with the inner flat gear ring 804. The rotating ring 801 drives the linkage gear 901 to rotate through the inner flat gear ring 804. The linkage gear 901 drives the rolling frame 902 to move on the vibration component. The vibration assembly includes a sleeve 1001 movably connected to a guide rod 108, a helical track 1002 installed inside the sleeve 1001, a return spring 1003 installed on the sleeve 1001, a connecting frame 1004 with one end installed on the sleeve 1001, and a vibration ball 1005 fixedly installed on the other end of the connecting frame 1004. One end of the return spring 1003 is connected to the sleeve 1001, and the other end is connected to the hanger 107. A linkage gear 901 drives a rolling frame 902 to move along the helical track 1002. When the rolling frame 902 moves along the helical track 1002, the sleeve 1001 moves along the guide rod 108. When the rolling frame 902 moves from the top of the helical track 1002 to the bottom of the helical track 1002, the sleeve 1001 drives the vibration ball 1005 away from the valve head 105 through the connecting frame 1004.When the rolling frame 902 moves from the bottom to the top of the spiral track 1002, the sleeve 1001 drives the vibrating ball 1005 to approach the valve head 105 via the connecting frame 1004. During rotation, the rotating ring 801 transmits power to the linkage gear 901 via the inner flat gear ring 804. The linkage gear 901 rotates and drives the rolling frame 902 to rotate along the spiral track 1002 (in this technical solution, the spiral track 1002 rotates one revolution). When the rolling frame 902 moves from the top to the bottom of the spiral track 1002, the spiral track 1002 is subjected to the reverse force of the rolling frame 902, pushing the sleeve 1001 to move upward against the elastic force of the return spring 1003, with the help of the connecting frame 1004. The frame 1004 drives the vibrating ball 1005 to gradually move away from the valve head 105. When the rolling frame 902 moves to the bottom of the spiral track 1002, it will instantly fall to the top of the spiral track 1002. Under the elastic action of the return spring 1003, the sleeve 1001 instantly returns to its original position, causing the vibrating ball 1005 to strike the valve head 105. The vibration causes the water around the valve head 105 to fluctuate (because the valve head 105 has a relatively complex structure and many dead angles, the water flow in the dead angles is not smooth and is prone to freezing. Therefore, the vibrating ball 1005 in this solution is used to cause the valve head 105 to vibrate, and the vibration causes the water to fluctuate to a certain extent, preventing the water around the valve head 105 from freezing).

[0039] Working principle: The user operates the valve stem 104, causing the valve head 105 to leave the channel opening, the valve chamber 101 opens, and water enters the valve chamber 101 from the inlet 102 and is discharged from the outlet 103. During the flow process, the water exerts a force on the blades of the turbine 201, causing the turbine 201 to rotate (the motor 601 is in the off state at this time, and the output end is not locked, so it can rotate with the turbine 201). The pulse signal (rotation speed) generated by the turbine 201 can be detected by the speed sensor 202. By calculating the number of pulses received per unit time, the water flow rate can be accurately calculated.

[0040] When it is necessary to close the valve chamber 101, the user operates the valve stem 104 to control the valve head 105 to move downward into the channel opening, thereby closing the valve chamber 101. As the valve stem 104 moves, the pressure plate 106 on it continuously squeezes the air cover 301, causing the gas in the air cover 301 to flow into the air bag 401 through the air supply pipe 302. The air bag 401 continuously expands, occupying more space in the valve chamber 101, and discharging the water that was originally accumulated in the valve chamber 101 (in actual applications, it can be squeezed into the water outlet pipe).

[0041] When the valve chamber 101 is completely closed, the pressure plate 106 moves to the preset position and applies a corresponding tension to the tension spring 501. The tension sensor 502 detects that the tension value of the tension spring 501 reaches F1 and sends a signal to the motor 601. The motor 601 drives the turbine 201 to rotate actively. The turbine 201 drives the rotating ring 801 with the outer bevel gear 802 to rotate through the transmission rod 701 and the transmission bevel gear 702, so that the baffle 803 continuously agitates the small amount of water accumulated around the valve head 105, preventing the water from freezing in low temperature conditions due to prolonged stagnation.

[0042] While the rotating ring 801 rotates, the power is transmitted to the linkage gear 901 through the internal flat gear. The linkage gear 901 drives the rolling frame 902 to rotate along the spiral track 1002. When the rolling frame 902 moves from the top to the bottom of the spiral track 1002, the spiral track 1002 is subjected to the reverse force of the rolling frame 902, which pushes the sleeve 1001 to move upward against the elastic force of the return spring 1003. This causes the connecting frame 1004 and the shock ball 1005 to gradually move away from the valve head 105. When the rolling frame 902 moves to the bottom of the spiral track 1002, the rolling frame 902 continues to move and will instantly fall from the bottom to the top of the spiral track 1002. Under the elastic action of the return spring 1003, the sleeve 1001 instantly returns to its original position, causing the shock ball 1005 to hit the valve head 105. The vibration causes the water around the valve head 105 to fluctuate, preventing the water from freezing.
