Description

Technical Field

[0001] The present invention relates to a valve, especially a valve applied to the fields of heat pump control, water conservancy heating, and cooling control, and can also be applied to fields such as water heaters and showers. Background Art

[0002] At present, the valve forms applied in many fields of heat pump control, water conservancy heating, and cold and hot water mixing are relatively single. Most rely on manual control, and a few add an electric control device to control the valve opening. However, the control method is single, it is easy to rust, and after being powered on, it increases the dangerous factors for controlling the valve, and it cannot meet the intelligent control requirements of diversified scenarios. Summary of the Invention

[0003] In view of this, the present invention provides an intelligent management valve, which can achieve efficient and intelligent control of the valve opening, without wiring, reduce the rust phenomenon in the pipeline valve, and at the same time reduce the possible dangerous factors in the pipeline valve, and does not require additional power supply or battery replacement, with precise and intelligent control.

[0004] In order to achieve the above intelligent management valve, the present invention provides the following technical solutions:

[0005] The intelligent management valve of the present invention includes: a water flow channel, and the water flow channel further includes an inlet channel and a return channel; it also includes an inlet, an outlet, a return water inlet, and a return water outlet. The characteristics are that: the inlet channel and the return channel have a common surface, and the common surface is made of a strong heat-conducting material, and the inside of the inlet channel and the return channel do not interfere with each other.

[0006] Preferably, the common surface is preferably made of aluminum alloy or magnesium alloy.

[0007] Furthermore, a return water primary coil is wound around the outside of the return water channel for one week; at the part covered by the return water primary coil, a permanent magnet rotor water flow turbine is installed inside the return water channel; on the incoming flow side of the rotor water flow turbine, a stator guide vane is installed.

[0008] Furthermore, an inlet water primary coil is wound around the outside of the inlet water channel for one week; at the part covered by the inlet water primary coil, a permanent magnet rotor water flow turbine is installed inside the inlet water channel; on the incoming flow side of the rotor water flow turbine, a stator guide vane is installed.

[0009] Preferably, the return water primary coil and the inlet water primary coil have no intersection and are respectively located on both sides of the common surface.

[0010] Preferably, the winding method of the coil is as follows: First, wind it into a plurality of flat ellipses. The number of winding turns is such that the thickness of the coil reaches one-tenth of the diameter of the water flow channel and does not exceed one-fifth of the diameter of the water flow channel. Then, align the long axes of the plurality of flat elliptical coils parallel to the water flow channel and evenly distribute them outside the water flow channel. There may be an overlap between the flat elliptical coils, and the overlapping area does not exceed one-half of the minor axis of the flat elliptical coil.

[0011] Furthermore, a thermoelectric generator is installed on the common surface.

[0012] Furthermore, an ECU, a super capacitor, a gate valve, a gate valve opening controller, a signal transceiver, a return water inlet temperature sensor, a water inlet temperature sensor, and an LED display are also integrated inside the valve.

[0013] Furthermore, the current output terminals of the return water primary coil, the current output terminals of the water inlet primary coil, the current output terminals of the thermoelectric generator, as well as the super capacitor, the valve opening controller, the signal transceiver, the return water inlet temperature sensor, the water inlet temperature sensor, and the LED display are all connected to the ECU. The ECU is responsible for the logical processing and control of the entire intelligent management valve. The super capacitor is used to store the electrical energy from the current output terminals of the return water primary coil, the current output terminals of the water inlet primary coil, and the current output terminals of the thermoelectric generator. The gate valve is located on the return water inlet side.

[0014] Furthermore, the ECU gives an instruction to the valve opening controller according to the signals from the water inlet temperature sensor and the return water inlet temperature sensor, and the valve opening controller controls the opening of the gate valve.

[0015] Furthermore, according to the instruction of the ECU, the LED display can display the temperature values of the current return water inlet temperature sensor and the water inlet temperature sensor, and can also display the temperature difference between the current return water inlet temperature sensor and the water inlet temperature sensor. The signal transceiver can perform data exchange with the terminal device wirelessly. At the terminal device, the valve opening can be indirectly controlled through the terminal control APP.

[0016] In summary, by rationally allocating different devices and the space of the flow channels, and making full use of the design of heat transfer and fluid mechanics, the present invention overcomes the problems of insufficient functionality and inconvenient use of current control valves. Most importantly, this intelligent control valve utilizes two self-power generation principles to overcome the inconvenience and safety issues brought about by the power supply of the intelligent module. Moreover, the intelligent module can feedback the current working state of the valve to the user terminal APP. The APP can give further instructions according to the user's needs. The ECU comprehensively calculates the required valve opening based on the temperature difference between the return water inlet temperature sensor and the inlet water temperature sensor according to the current instruction data, and sends it to the gate valve opening controller. At the same time, on the LED display of the intelligent control valve, the inlet water temperature, the return water temperature, and the temperature difference between the two are alternately displayed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] As Figure 1 shown, an intelligent management valve includes a water flow channel, and the water flow channel further includes an inlet channel 101 and a return water channel 102; it also includes an inlet water inlet 1011, an inlet water outlet 1012, a return water inlet 1021, and a return water outlet 1022. The characteristics are as follows: The inlet channel 101 and the return water channel 102 have a common surface 2, the common surface is made of a strong heat-conducting material, and the interiors of the inlet channel 101 and the return water channel 102 do not interfere with each other.

[0022] Considering that the water inlet channel and the water return channel do not interfere with each other, the common surface can preferably be made of aluminum alloy or magnesium alloy. On the one hand, the thermal conductivity of these two alloy materials is high, which can achieve better heat energy exchange. On the other hand, these two alloys have good corrosion resistance and are not easily corroded under the action of water flow. Even if a thermoelectric generator is installed, electrochemical corrosion will not occur. At the same time, aluminum alloy or magnesium alloy has a small density, a small volume mass, a lighter and thinner structure, which is beneficial to weight reduction, and is easy to process, with good cost control.

[0023] A primary return water coil 301 is wound around the outer circumference of the water return channel; at the part covered by the primary return water coil 301, a permanent magnet rotor water flow turbine 3011 is installed inside the water return channel; on the incoming flow side of the permanent magnet rotor water flow turbine, a stator guide vane 3012 is installed.

[0024] The coil is located outside the water flow channel, and the inner rotor is a permanent magnet. In this way, the intelligent management valve can be made as a whole, without the problems of sealing difficulties and reduced service life caused by opening holes in the water flow channel for conductive lines, control lines, etc. The stator guide vane can guide the incoming water flow. Using the "velocity triangle" principle, the twist angle of the stator vane is reasonably designed to reduce the flow loss of enthalpy, reduce the large flow loss at the blade basin or blade back of the permanent magnet rotor water flow turbine, so that the water flow impacts the permanent magnet rotor water flow turbine in a more efficient way, thereby making more effective use of the limited water flow energy.

[0025] According to the actual energy consumption calculation, a set of power generation devices can be added: a primary inlet water coil is wound around the outer circumference of the water inlet channel; at the part covered by the primary inlet water coil, a permanent magnet rotor water flow turbine is installed inside the water inlet channel; on the incoming flow side of the rotor water flow turbine, a stator guide vane is installed. The overall operation mode is as described in the previous paragraph.

[0026] A preferred configuration is that the primary return water coil and the primary inlet water coil have no intersection and are respectively located on both sides of the common surface. In order to prevent electromagnetic interference generated by the two installed coils, the two coils are distributed on the left and right sides of the intelligent management valve and have no intersection. Since there is a certain distance between them and they are separated by the common surface, the mutual magnetic field interference between the permanent magnet rotor water flow turbines is prevented.

[0027] In order to improve the electric energy conversion efficiency, the winding method of the coil is as follows: first wind it into a plurality of flat ellipses, and the number of winding turns is such that the thickness of the coil reaches one-tenth of the diameter of the water flow channel and does not exceed one-fifth of the diameter of the water flow channel; then the long axes of the plurality of flat elliptical coils are parallel to the water flow channel and are evenly distributed outside the water flow channel; there can be overlap between the flat elliptical coils, and the overlap area does not exceed one-half of the short axis of the flat elliptical coil. This arrangement method improves the change rate of magnetic flux and the power generation efficiency.

[0028] Furthermore, in order to reduce the situation where the flow rate in the pipeline is small, the rotational speed of the permanent magnet rotor water flow turbine is insufficient, and the electric energy is insufficient, a thermoelectric generator is installed on the common surface. By utilizing the temperature difference between the water inlet channel and the water return channel, an energy supplement effect is achieved, and the energy utilization rate inside the pipeline is improved.

[0029] The electronic equipment cabin inside the valve also integrates an ECU, a super capacitor, a barrier gate valve, a barrier gate valve opening controller, a signal transceiver, a water return inlet temperature sensor, a water inlet temperature sensor, and an LED display.

[0030] The ECU is responsible for receiving, calculating, and sending commands for the entire electronic control part of the intelligent management valve; the super capacitor is used to store the electric energy coming from the above three parallel channels for the continuous and stable operation of the intelligent device; the barrier gate valve opening controller receives commands from the ECU and adjusts the opening of the barrier gate valve through a stepper motor to control the flow rate, thereby further controlling parameters such as temperature; the signal transceiver can be devices such as WIFI, 4G, 5G, Bluetooth, etc., used to achieve public network communication or direct connection communication with the terminal device; the water return inlet temperature sensor and the water inlet temperature sensor are used to detect the current temperatures of the water return inlet and the water inlet; the LED display can display the current information of the intelligent management valve.

[0031] The current output terminals of the water return primary coil, the current output terminals of the water inlet primary coil, the current output terminals of the thermoelectric generator, as well as the super capacitor, the valve opening controller, the signal transceiver, the water return inlet temperature sensor, the water inlet temperature sensor, and the LED display are all connected to the ECU; the ECU is responsible for the logical processing and control of the entire intelligent management valve; the super capacitor is used to store the electric energy from the current output terminals of the water return primary coil, the current output terminals of the water inlet primary coil, and the current output terminals of the thermoelectric generator; the barrier gate valve is located on the water return inlet side.

[0032] The ECU gives commands to the valve opening controller according to the signals of the water inlet temperature sensor and the water return inlet temperature sensor, and the valve opening controller controls the opening of the barrier gate valve.

[0033] According to the commands of the ECU, the LED display can display the temperature values of the current water return inlet temperature sensor and the water inlet temperature sensor, or the temperature difference between the current water return inlet temperature sensor and the water inlet temperature sensor; the signal transceiver can exchange data with the terminal device wirelessly, and at the terminal device, the valve opening can be indirectly controlled through the terminal control APP.

[0034] Indirect control method: The terminal APP sends instructions according to the currently set temperature. After the signal transceiver device receives the signal, it is transmitted to the ECU. The ECU processes the received instructions and the temperature difference between the return water inlet temperature sensor and the inlet water temperature sensor, calculates the required opening degree of the gate valve, and adjusts the opening degree.

[0035] In summary, by using different devices and pipeline structure designs and making full use of fluid mechanics design, the present invention overcomes the shortcomings of the current single valve control method and the inability to achieve intelligence. Most importantly, by paralleling a new type of energy supply device, the problem of inconvenient power supply for the intelligent module is overcome, and the intelligent module can feedback the current internal situation of the pipeline to the user terminal APP, and the terminal APP can also send instructions to the intelligent management valve to control the opening degree of the valve.
