Description

Technical Field

[0001] This utility model relates to the field of valve equipment technology, and in particular to a multi-channel distribution valve with a prompting function. Background Technology

[0002] A multi-channel distribution valve (hereinafter referred to as a multi-channel distribution valve) is a valve device that distributes fluid (liquid or gas) to multiple outlets through a single inlet. Its core function is flow control, and it is widely used in industrial, residential, and fluid system management scenarios. Based on their structure, multi-channel distribution valves are generally divided into mechanical and solenoid valve types. In mechanical multi-channel distribution valve applications, the operator manually or through a servo motor mechanism rotates the valve core to the corresponding outlet position, thus allowing fluid to enter from the inlet and exit from the corresponding outlet. In solenoid valve-based multi-channel distribution valve applications, the operator controls different solenoid valves to operate via a power switch, thus allowing fluid to enter from the inlet and exit from the outlet of one or more open solenoid valves. Solenoid-type multi-channel distribution valves have a significantly reduced wear rate due to the absence of rotating parts inside (and the ability to operate with one inlet and multiple outlets). This makes them relatively reliable and widely used. (Specifically, in mechanical multi-channel distribution valves, the valve core needs to rotate, causing wear at the corresponding rotating contact points with the valve seat, leading to poor sealing over time. In contrast, in solenoid-type multi-channel distribution valves, the valve core moves back and forth under the action of an internal electromagnet and spring, opening and closing without any rotational contact with the valve seat, resulting in less wear.)

[0003] With the advancement of industrial technology, multi-channel distribution valve technology based on solenoid valves has also developed to some extent. However, due to structural limitations, it still faces some technical problems. Firstly, operation generally requires operators to approach and individually turn on or off the corresponding power switches to control the energization or de-energization of different solenoid valves. This can be inconvenient for operators. Although some solenoid valve-based multi-channel distribution valves can be wirelessly controlled, operators do not receive operational feedback during wireless control. In other words, after a set of solenoid valves is energized wirelessly, operators may not observe the flow of the medium at the corresponding outlet. Therefore, due to lack of awareness, control failures (such as interference with the wireless signal, resulting in the solenoid valve not being energized or de-energized) can lead to input and output control failures. Secondly, external power supply or battery charging is required, which is inconvenient for practical applications (requiring the installation of power lines or regular battery charging), and also incurs power supply costs. Thirdly, it lacks input medium monitoring function. When the input medium stops, it will not receive timely prompts for processing, which may have an adverse impact on some production areas (for example, a certain production process cannot continue production because the input of liquid raw materials stops). Utility Model Content

[0004] To overcome the shortcomings of existing solenoid valve-type multi-channel distribution valves, which are limited by their structure and have the drawbacks described in the background, this utility model provides a multi-channel distribution valve with a prompting function that, under the combined action of related structures, does not require an external power supply. It allows operators to conveniently control the operation of different solenoid valves wirelessly, and provides real-time wireless feedback to operators on the effectiveness of their operations. It also promptly alerts operators wirelessly when the medium input at the input end stops. This achieves energy saving, convenience for operators, ensures operational accuracy, and enables the production equipment using the applied medium to operate normally.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A multi-channel distribution valve with a prompting function includes a housing, a battery, solenoid valves, a hydrogenerator, a pressure sensor, a wireless receiver module, a main pipe, and a wireless transmitter circuit module. It also includes a feedback receiving and control circuit, a detection circuit, and a transmitting circuit. Multiple sets of solenoid valves and pressure sensors are included. Multiple branch pipes are installed on the side of the main pipe. The inlets of the multiple solenoid valve sets and the side ends of the multiple branch pipes are respectively installed together. The multiple solenoid valve sets and the main pipe are installed inside the housing. The outlets of the multiple solenoid valve sets are connected to one end of each of the multiple output pipes, and the other ends of the multiple output pipes are connected to multiple media input pipes in the production area. The upper end of the main pipe is connected to the output end of the hydrogenerator, and the input end of the hydrogenerator is connected to the media output pipe. The system is connected in a manner that includes multiple pressure sensors, the inlet pipe of another pressure sensor, multiple output pipes, and the main pipe, all mounted together. The battery, detection circuit, transmitting circuit, and wireless receiving module are installed in a component box. The two terminals of the battery are electrically connected to the power input terminals of the wireless receiving module, multiple pressure sensors, detection circuit, and transmitting circuit. The multiple signal input terminals of the transmitting circuit are electrically connected to the signal output terminals of multiple pressure sensors and detection circuits. The signal input terminal of the detection circuit is electrically connected to the signal output terminal of another pressure sensor. The multiple power output terminals of the wireless receiving module are electrically connected to the power input terminals of multiple solenoid valves. The feedback receiving and control circuit is installed in an electrical control box.

[0007] Furthermore, the solenoid valve is a normally closed valve core solenoid valve.

[0008] Furthermore, the transmitting circuit includes electrically connected resistors, transistors, relays, and a wireless transmitting circuit module A. One end of each of the five resistors is connected to the base of each of the five transistors. The collectors of each of the five transistors are connected to the negative power input terminals of each of the five relays. The emitters of each of the five transistors are connected to the negative power input terminal of the wireless transmitting circuit module A. The positive power input terminals of each of the five relays are connected to the positive power input terminal of the wireless transmitting circuit module A. The control contacts and normally open contacts of each of the five relays are connected to the two contacts below each of the five transmit buttons in the wireless transmitting circuit module A.

[0009] Furthermore, the detection circuit includes an electrically connected resistor, a transistor, and a relay. One end of the first resistor and one end of the second resistor are connected to the base of the first transistor. The collector of the first transistor and the base of the second transistor are connected to one end of the third resistor. The other end of the third resistor is connected to the positive power input terminal of the relay. The emitters of the two transistors are connected to the other end of the second resistor.

[0010] Furthermore, the feedback receiving and control circuit includes an electrically connected power module and indicator lights, and a wireless receiving circuit module A. The power input terminal of the wireless receiving circuit module A is connected to the power output terminal of the power module, and the multiple power output terminals of the wireless receiving circuit module A are respectively connected to the power input terminals of multiple indicator lights.

[0011] Furthermore, the encoding circuits of the wireless transmitting circuit module and the wireless receiving circuit module are identical, and the encoding circuits of the wireless transmitting circuit module A and the wireless receiving circuit module A are identical.

[0012] Compared with existing technologies, the advantages of this invention are as follows: During operation, the inflow and outflow of the medium (such as water) causes the water flow to impact the generator, which generates electricity, and the battery stores the electricity to power the entire circuit, saving electricity costs. Furthermore, it eliminates the need for wiring, making its application more flexible and convenient. Operators in the control room or other locations can easily control one or more sets of solenoid valves to be energized or de-energized via a portable wireless transmission module. The system also provides real-time wireless feedback to operators via different indicator lights, indicating whether the operation is effective, and promptly alerts operators wirelessly when the medium input stops. This invention achieves energy savings, provides convenience to operators, ensures operational accuracy, and enables the production equipment using the applied medium to operate normally. In summary, this invention has promising application prospects. Attached Figure Description

The right side of the other end of each of the five output pipes 22 is connected to the five medium (e.g., water) input pipes in the production area via pipes. The main pipe 2 is located on the upper outer side of the outer casing 1 and is fixedly connected to the output end of the water flow generator M via threads. The input end of the water flow generator M is connected to the main medium input pipe via pipes. There is a threaded hole on the upper right end of each of the five output pipes 22 and the upper right side of the main pipe. The inlet pipes of the five pressure sensors (A2) and the other pressure sensor (A7) are fixedly installed together with the threaded holes on the upper right end of the five output pipes 22 and the upper right side of the main pipe 2, and the inlet pipes are interconnected with the main pipe and the output pipes.

[0017] Figure 1 , 2As shown in Figure 3, solenoid valves DC1, DC2, DC3, DC4, and DC5 are normally closed solenoid valves. The transmitting circuit includes resistor R1, transistor T1, relay K1, and wireless transmitting circuit module AA3 connected via circuit board wiring. One end of each of the five resistors R1 (only one is shown in the figure) is connected to the base of each of the five transistors T1 (only one is shown in the figure). The collectors of each of the five transistors T1 are connected to the negative power input terminals of each of the five relays K1 (only one is shown in the figure). The emitters of each of the five transistors T1 are connected to pin 2 of the negative power input terminal of wireless transmitting circuit module AA3. The positive power input terminals of each of the five relays K1 are connected to pin 1 of the positive power input terminal of wireless transmitting circuit module AA3. The control contacts and normally open contacts of each of the five relays K1 are connected to the lower two contacts of each of the five transmitting buttons D1, D2, D3, D4, and D5 of wireless transmitting circuit module AA3. The detection circuit includes resistors R2, R3, and R4 connected via circuit board wiring, transistors T2 and T3, relay K2, one end of the first resistor R2 and one end of the second resistor R3 connected to the base of the first transistor T2, the collector of the first transistor T2 and the base of the second transistor T3 connected to one end of the third resistor R4, the other end of the third resistor R4 connected to the positive power input terminal of relay K2, and the emitters of the two transistors T2 and T3 connected to the other end of the second resistor R3. The feedback receiving and control circuit includes a power module A4 and indicator lights H1, H2, H3, H4, H5, H6, and a wireless receiving circuit module AA5, all connected via circuit board wiring. The power input terminals 1 and 2 of the wireless receiving circuit module AA5 are connected to the power output terminals 3 and 4 of the power module A4. The six power output terminals 3, 4, 5, 6, 7, 8, and pin 2 of the wireless receiving circuit module AA5 are connected to the power input terminals of the six indicator lights H1, H2, H3, H4, H5, and H6. The encoding circuits of the wireless transmitting circuit module and the wireless receiving circuit module A1 (A6) are identical. The encoding circuits of the wireless transmitting circuit module AA3 and the wireless receiving circuit module AA5 are identical. However, the encoding circuits of the wireless transmitting circuit module A6, the wireless receiving circuit module A1, the wireless transmitting circuit module AA3, and the wireless receiving circuit module AA5 are inconsistent.

[0018] Figure 1 , 2As shown in Figure 3, the two terminals of the battery G1 and pins 1 and 2 of the wireless receiver module A1, the power input terminals 1 and 2 of the six pressure sensors A2 (A7), the power input terminal of the detection circuit, the positive power input terminal of relay K2 and the emitter of transistor T2, the power input terminal of the transmitting circuit, the positive power input terminal of relay K1 and the emitter of transistor T1, and the two terminals of the water flow generator M are connected by wires. The other end of the five resistors R1 in the transmitting circuit and the signal output terminal pin 3 of the five pressure sensors A2 are connected by wires. The signal output terminal of the detection circuit relay K2, the control power input terminal and the normally open contact terminal are connected to the two contacts under the sixth transmit button D6 of the wireless transmitting circuit module AA3 via wires; the other end of the signal input terminal resistor R2 of the detection circuit is connected to the signal output terminal pin 3 of another pressure sensor A7 via wires; the five power output terminals pins 3, 4, 5, 6, 7 and pin 2 of the wireless receiving module A1 are connected to the power input terminals of the five sets of solenoid valves DC1, DC2, DC3, DC4 and DC5 via wires.

[0019] Figure 1 , 2As shown in Figure 3, after the AC 220V power supply enters the power input terminal of the power module A4, the power module A4 outputs a stable DC 12V power supply through pins 3 and 4, which enters the power input terminal of the wireless receiver circuit module AA5, thus powering and enabling the wireless receiver circuit module AA5 to operate. In operation, the medium (such as water) flows in and out through the water flow generator M. When it flows out through one or more sets of solenoid valves, the water flow generator M is impacted by the water flow to generate electricity (charging the battery G2 and powering the wireless receiver circuit module A1, as well as the transmitting and receiving circuits). The battery G2 stores electricity to power all circuits, saving on electricity costs and eliminating the need for wiring, making its application more flexible and convenient. When staff in the control room need to control the valve cores of solenoid valves DC1, DC2, DC3, DC4, or DC5 to open and supply water to the corresponding pipelines, they press button D1 or D2, D3, D4, or D5 on the wireless transmitting circuit module A6. The wireless transmitting circuit module A6 will transmit a first, second, third, fourth, or fifth wireless closing signal. After receiving the first, second, third, fourth, or fifth wireless closing signal, the wireless receiving circuit module A1 will output a high level from pins 3 or 4, 5, 6, or 7, which will then enter the power input terminal of the solenoid valves DC1, DC2, DC3, DC4, or DC5. In this way, the valve cores of solenoid valves DC1, DC2, DC3, DC4, or DC5 will be energized and open. The medium input from the main medium input pipe will then be supplied to the corresponding pipelines (such as water) via solenoid valves DC1, DC2, DC3, DC4, or DC5. When staff in the control room need to close the valve cores of solenoid valves DC1, DC2, DC3, DC4, or DC5 to stop water supply to the corresponding pipeline, they can press button D1, D2, D3, D4, or D5 on the wireless transmitting circuit module A6 again. The wireless transmitting circuit module A6 will then transmit one or more open-circuit wireless signals. The wireless receiving circuit module A1 will then receive these signals. When pins 3 or 4, 5, 6, and 7 stop outputting a high level to the power input terminals of solenoid valves DC1, DC2, DC3, DC4, and DC5, the solenoid valves DC1, DC2, DC3, DC4, and DC5 will lose power and stop working, causing the valve core to close. The medium input through the main medium input pipe will no longer be fed into the corresponding pipeline via solenoid valves DC1, DC2, DC3, DC4, and DC5 (e.g., water).

[0020] Figure 1 , 2As shown in Figure 3, in this new invention, after the operator wirelessly controls the corresponding solenoid valve to open, the medium input through the medium input pipe is discharged through the corresponding pipe. Due to the increased pressure of the medium inflow, the pressure sensor A2 outputs a relatively high voltage signal at pin 3. This signal is then reduced and current-limited by the resistor R1 and enters the base of the transistor T1. The transistor T1 conducts, and its collector outputs a low level, which enters the negative power input terminal of the relay K1. The relay K1 is energized and its control contact and normally open contact are closed. Since the two contacts of the corresponding button D1 or D2, D3, D4, D5 of the wireless transmission circuit module AA3 are connected to the control contact and normally open contact of the relay K1, the wireless transmission circuit module AA3 will transmit the first, second, third, fourth, or fifth wireless closing signal. When the staff wirelessly controls the corresponding solenoid valve to close the valve core, the medium input from the medium input pipe no longer exits through the corresponding pipe. Due to the cessation of medium flow, the pressure in the corresponding pipe decreases. As the detected pressure decreases, the pressure sensor A2 outputs a relatively low voltage signal at pin 3. The transistor T1 is cut off, and its collector stops outputting a low level to the negative power input terminal of the relay K1. The relay K1 is de-energized and no longer engages, opening its control contact and normally open contact. The wireless transmission circuit module AA3 will stop transmitting the first, second, third, fourth, or fifth wireless closing signal. When the main medium input pipe is normally receiving medium, the inflow pressure of the medium in the main medium input pipe increases (for example, higher than 0.6MPa). Due to the increased pressure detected, the pressure sensor A7 outputs a relatively high voltage signal at pin 3, which is divided by resistors R2 and R3 and enters the base of transistor T2 (higher than 0.7V). Transistor T2 conducts, and the collector outputs a low level that enters the base of transistor T3. Transistor T3 is cut off without a suitable forward bias voltage, relay K2 will not be energized and will not engage. The wireless transmission circuit module AA3 will not transmit the sixth wireless closing signal.When the input medium in the main medium inlet pipe is abnormal (e.g., below 0.6MPa), the inflow pressure of the medium in the main medium inlet pipe decreases. Due to the reduced pressure detected, the pressure sensor A7 outputs a relatively low voltage signal at pin 3, which is divided by resistors R2 and R3 and enters the base of transistor T2 (below 0.7V). Transistor T2 is cut off, and its collector no longer outputs a low level, which enters the base of transistor T3. The base of transistor T3 is reduced and current limited by resistor R4 to obtain a suitable positive bias voltage, which turns on its collector and outputs a low level, which enters the negative power input terminal of relay K2. Relay K2 is energized and its control contact and normally open contact are closed. Since the two contacts under button D6 of the wireless transmission circuit module AA3 are connected together with the corresponding control contact and normally open contact of one relay K2 (equivalent to a person pressing button D6), the wireless transmission circuit module AA3 will transmit a sixth wireless closing signal.

[0021] Figure 1 , 2 As shown in Figure 3, when the operator wirelessly controls the corresponding solenoid valve and the medium input to the main medium input pipe is abnormal, the wireless transmitting circuit module AA3 transmits the first, second, third, fourth, fifth, or sixth wireless closing signal. After the wireless receiving circuit module AA5 receives the signal, its pins 3, 4, 5, 6, 7, and 8 will output a high level to the power input terminals of indicator lights H1, H2, H3, H4, H5, and H6. The indicator lights H1, H2, H3, H4, H5, and H6 will then light up. In this way, the staff on duty in the office can understand whether the control of the corresponding solenoid valve is successful by observing the illumination of indicator lights H1, H2, H3, H4, and H5 (the illumination of one indicator light indicates successful wireless control of the corresponding solenoid valve). When indicator light H6 lights up, it indicates that the medium input to the main medium input pipe is abnormal (such as low pressure). When the control of the corresponding solenoid valve fails or the medium input to the main medium input pipe is abnormal, the staff can go to the site for maintenance and repair. Figure 2 , 3In the diagram, power module A4 is a finished product of AC 220V to DC 12V power module; battery G1 is a 12V / 5Ah lithium battery; solenoid valves DC1, DC2, DC3, DC4, and DC5 are normally closed solenoid valves with a power of 2W; indicator lights H1, H2, H3, H4, H5, and H6 are small red 1W light bulbs (LEDs can also be used, with the emitting surface located outside the six openings at the front of the control box); transistors T1, T2, and T3 are model 9013 (NPN); relays K1 and K2 are model DC12V; resistors R1, R2, R3, and R4 have resistance values ​​of 10K, 47K, 4.7K, and 100K respectively (the higher the resistance value of resistor R2, the lower the resistance of transistor T2 when the medium pressure is higher). The transistor T2 will conduct when the medium pressure is low, meaning the pressure threshold of this new type is set relatively high. The smaller the resistance of resistor R2, the lower the medium pressure will be, and the transistor T2 will conduct. This means the pressure threshold of this new type is set relatively low. Wireless transmitting circuit module A6, wireless receiving circuit module A1, wireless transmitting circuit module AA3, and wireless receiving circuit module AA5 are six-channel wireless transmitting and receiving components with a wireless transmission and reception distance of 2000 meters (consistent with the principle and function of wireless transmitting and receiving modules used in vehicles, etc.). Wireless transmitting circuit module A6 and wireless receiving circuit module A1 operate in self-locking mode, while wireless transmitting circuit module AA3 and wireless receiving circuit module AA5 operate in jogging mode. The water flow generator M outputs a DC 12V voltage and a power of 10W. Pressure sensors A2 and A7 are finished pressure transmitters of model QDX50A-VD, which have two power input terminals and one signal output terminal.
