Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, and in particular to remote control valves. Background Technology

[0002] With the rapid development of urban gas networks and industrial gas systems, automatic valve control has become an important technical means to ensure the safe operation of gas systems. Gas valve pneumatic actuators control the opening, closing, or adjustment of valves through air pressure, thereby achieving precise management of gas flow. Solenoid valves, on the other hand, can control the opening and closing of the gas source to supply gas to the pneumatic actuators. They are widely used in gas pipelines, industrial equipment, and other scenarios that require remote or automatic control to ensure the safe and efficient operation of the system.

[0003] Common remote control valves can only be controlled by a remote PC or mobile device to open and close the solenoid valve, but they lack the function of limiting the air tube. When the air source supplies air to the solenoid valve through the air tube, the impact force of the air moving in the air tube will cause the air tube to swing unpredictably. Over time, this will cause the connection between the air inlet of the solenoid valve and the air tube to loosen, resulting in air leakage from the loose connection between the air inlet of the solenoid valve and the air tube, ultimately causing the problem of insufficient air supply.

[0004] Therefore, to address the problem of the lack of a tracheal limiting function, where the gas supply to the solenoid valve via the tracheal tube causes irregular swinging of the tracheal tube due to gas impact, and long-term use will loosen the connection between the solenoid valve's inlet and the tracheal tube, affecting the gas supply, a remote control valve can be designed. Utility Model Content

[0005] To overcome the problem of the lack of a tracheal limiting function, when the air source supplies air to the solenoid valve through the tracheal tube, the gas impact force will cause the tracheal tube to swing irregularly. Long-term use will loosen the connection between the air inlet of the solenoid valve and the tracheal tube, affecting the air supply.

[0006] The technical solution of this utility model is as follows: a remote control valve, including a remote solenoid valve body; it also includes a vertical slot and an arc-shaped clamping plate. Two supporting vertical plates are fixedly connected to the top of the remote solenoid valve body, and a positioning plate is fixedly connected between the two supporting vertical plates. A vertical slot is opened on the front side of the positioning plate. Two telescopic rods are fixedly connected to the side of each of the two supporting vertical plates near the positioning plate. An arc-shaped clamping plate is fixedly connected to the end of the telescopic rod away from the supporting vertical plate. A pipe limiting mechanism is provided on the remote solenoid valve body. The pipe limiting mechanism is used to position and store the air pipe. An air inlet and outlet mechanism is provided on the remote solenoid valve body. The air inlet and outlet mechanism is used to receive and release the air source.

[0007] Preferably, by pulling the two arc-shaped clamps to separate them, the telescopic rod and spring are compressed and contracted. Then, the air tube is placed between the two separated arc-shaped clamps. Subsequently, the two arc-shaped clamps are released, and the spring pushes the two reset plates closer to each other. The reset plates then drive the telescopic rod to extend until the two telescopic rods push the two arc-shaped clamps together to hold the air tube. Finally, the unclamped middle section of the air tube is inserted into the vertical slot, thereby restricting the position of the air tube and realizing the function of air tube limiting.

[0008] Preferably, the tube limiting mechanism includes a storage component and a reset component. The storage component is used to store the trachea, and the reset component is used to keep the two clamps in a clamped state.

[0009] Preferably, the storage component includes a serpentine slot on the front side of the positioning plate, the serpentine slot having the same axis as the vertical slot.

[0010] Preferably, the reset assembly includes a reset plate fixed to the outside of the telescopic end of the telescopic rod, a spring fixed to the side of the reset plate away from the arc-shaped clamp, and the end of the spring away from the reset plate is fixedly connected to the support vertical plate.

[0011] Preferably, the air inlet / outlet mechanism includes an air inlet assembly and an air outlet assembly. The air inlet assembly is used to receive air from the source and enter the interior of the remote solenoid valve body, and the air outlet assembly is used to discharge the received air source.

[0012] Preferably, the air intake assembly includes an air intake port fixed to the top of the remote solenoid valve body, two exhaust ports fixed to the top of the remote solenoid valve body, and two wooden plugs fixed inside the two exhaust ports.

[0013] Preferably, the air outlet assembly includes an A air outlet fixed to the bottom of the remote solenoid valve body and a B air outlet fixed to the bottom of the remote solenoid valve body.

[0014] Preferably, a terminal housing is fixedly connected to the bottom of the remote solenoid valve body, and a wiring port is fixedly connected to the right side of the terminal housing.

[0015] The beneficial effects of this utility model are:

[0016] This structure, through the synergy of a spring-driven automatic clamping mechanism and a slot, achieves reliable, adaptive clamping and stable mid-section positioning of the air tube. It effectively suppresses the swinging phenomenon of the air tube caused by gas impact during air supply, thereby fundamentally avoiding the loosening and gas leakage problems caused by long-term vibration at the connection between the air tube and the solenoid valve. This ensures the stability and continuity of air supply and improves the reliability of system operation. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] With the acceleration of urbanization and the vigorous development of industrial production, natural gas, as a clean and efficient energy source, is increasingly widely used in urban residents' lives and industrial production. However, natural gas has characteristics such as flammability, explosiveness, and toxicity, and its safe operation is related to the safety of people's lives and property and the stable development of society. Against this background, the automatic control technology of gas systems has become the key to ensuring the safe and efficient operation of gas systems. Among them, gas valve pneumatic actuators and solenoid valves, as the core components of automatic control of gas systems, play an irreplaceable role.

[0025] A gas valve pneumatic actuator is a device that uses compressed gas as a power source to control the opening, closing, or regulation of a valve by changing the gas pressure. It can convert gas pressure signals into mechanical actions, thereby achieving precise management of gas flow. Its working principle is based on the basic theory of pneumatic control. When the control system issues a command, compressed gas enters the cylinder of the pneumatic actuator through the air pipe, pushing the piston or diaphragm to move, which in turn drives the valve stem to rotate or translate, changing the valve opening.

[0026] Secondly, pneumatic actuators for gas valves have a large output force; the compressed gas can provide significant pressure, enabling the actuator to drive large-diameter valves and meet the needs of high-flow-rate gas delivery in industrial gas systems. In the gas pipelines of some large industrial enterprises, large-diameter valves are required to control the gas delivery, and pneumatic actuators, with their powerful output force, can easily control these valves.

[0027] Furthermore, it has high reliability. The structure of pneumatic actuators is relatively simple, without complex electronic components, which reduces the probability of failure. At the same time, compressed gas has good explosion-proof performance, enabling pneumatic actuators to work safely and reliably in flammable and explosive gas environments, avoiding safety accidents caused by electrical faults.

[0028] In addition, the maintenance cost of gas valve pneumatic actuators is low. Due to their simple structure and few parts, they do not require complex technology or expensive equipment in daily maintenance. Maintenance personnel can easily inspect, repair and replace parts, which greatly reduces maintenance costs and downtime and improves the operating efficiency of the gas system.

[0029] The solenoid valve is a key component controlling the opening and closing of the air source and supplying air to the pneumatic actuator. It is a valve that operates based on the principle of electromagnetic induction and consists of an electromagnetic coil, an iron core, and a valve body. When the electromagnetic coil is energized, the generated electromagnetic force attracts the iron core to move, which in turn moves the valve core in the valve body, opening the valve and allowing compressed gas to enter the pneumatic actuator through the solenoid valve. When the electromagnetic coil is de-energized, the electromagnetic force disappears, the valve core returns to its original position under the action of the spring, the valve closes, and the air source is cut off.

[0030] Solenoid valves are characterized by their small size, light weight, rapid action, and high control precision. They can quickly respond to the commands of the control system and achieve precise control of the gas source, thereby ensuring that the pneumatic actuator can operate as expected. In the gas system, the performance of the solenoid valve directly affects the working reliability of the pneumatic actuator and the safety of the gas system.

[0031] In gas pipelines, the coordinated use of pneumatic actuators and solenoid valves is crucial. Urban gas pipeline networks are intricate and cover a wide area, requiring precise control of gas flow in each section to ensure a stable and even delivery of gas to all users. When gas demand in a certain area changes, the control system issues a command to control the pneumatic actuator via the solenoid valve, adjusting the valve opening and changing the gas flow. For example, during peak residential gas consumption periods, when the gas supply needs to be increased, the solenoid valve opens, the pneumatic actuator activates, and the valve opening is increased to increase the gas flow. Conversely, during off-peak gas consumption periods, the valve opening is reduced to decrease the gas flow and prevent gas from accumulating in the pipeline, which could cause excessive pressure.

[0032] In terms of safety protection for gas pipelines, pneumatic actuators and solenoid valves play a crucial role. When gas pipelines experience leaks, abnormal pressure, or other malfunctions, sensors installed on the pipelines will promptly detect these abnormal signals and transmit them to the control system. Upon receiving the signal, the control system will quickly issue a command to close the solenoid valve, cutting off the gas supply to the pneumatic actuator. Under the action of the return spring, the pneumatic actuator will close the valve, cutting off the gas supply and preventing further gas leakage, thus avoiding safety accidents such as explosions and poisoning. At the same time, the control system will also issue an alarm signal to remind staff to carry out timely maintenance and handling.

[0033] In industrial equipment, pneumatic actuators and solenoid valves for gas valves are also widely used. In industrial production processes, gas is often used as fuel or raw material, and the stability of its flow and pressure directly affects the stability of the production process and the quality of the product. For example, in the steel smelting process, high temperatures are required through gas combustion. Unstable gas flow can lead to furnace temperature fluctuations, affecting the quality of the steel. Pneumatic actuators can precisely adjust the opening of gas valves to ensure stable gas flow. Solenoid valves can quickly respond to the instructions of the control system, promptly opening or closing the gas source, ensuring that the gas supply can be adjusted at any time according to process requirements during the production process.

[0034] In some hazardous industrial environments, such as gas-fired workshops in chemical plants, gas leaks can lead to serious safety accidents. The explosion-proof performance of gas valve pneumatic actuators and solenoid valves plays an important role here. They can work safely in flammable and explosive environments and can quickly cut off the gas supply when dangerous situations such as gas leaks are detected, thus ensuring safe production in the workshop.

[0035] Furthermore, pneumatic actuators and solenoid valves are widely used in gas storage and transportation. Gas storage and distribution stations are important nodes in the gas supply system, responsible for the storage, pressurization, and transportation of gas. In these stations, parameters such as gas inflow and outflow rate and pressure need to be strictly controlled to ensure safe operation. Pneumatic actuators and solenoid valves can precisely control the actions of various valves, enabling automated management of the gas storage and transportation process. For example, during the gas inflow and outflow process of gas storage tanks, pneumatic actuators can adjust the valve opening to control the gas flow rate and volume, preventing safety accidents caused by excessive flow rate or volume.

[0036] With the continuous advancement of technology, the technology of gas valve pneumatic actuators and solenoid valves is also constantly innovating and developing. Intelligentization and networking have become important trends in their development. Intelligent pneumatic actuators and solenoid valves can monitor their own working status and the operating parameters of the gas system in real time through sensors, and transmit this information to the control system through the network to realize remote monitoring and diagnosis. Staff can understand the operation of the equipment at any time in the control center, promptly detect and handle faults, and improve the management efficiency and safety of the gas system.

[0037] Meanwhile, in order to adapt to different working environments and operating conditions, the materials and performance of pneumatic actuators and solenoid valves for gas valves are constantly being optimized. For example, in some highly corrosive industrial gas environments, actuators and solenoid valves made of corrosion-resistant materials can improve the service life and reliability of the equipment. In addition, by improving the design and manufacturing process, the precision and stability of the equipment have been improved, further ensuring the safe and efficient operation of the gas system.

[0038] However, in practical applications, gas valve pneumatic actuators and solenoid valves also face some challenges. For example, in some remote areas or harsh environments, the supply of compressed air may be unstable, affecting the normal operation of the pneumatic actuators. In this case, corresponding measures need to be taken, such as equipping backup air source equipment, to ensure the reliable operation of the pneumatic actuators. In addition, with the continuous expansion and increasing complexity of gas systems, higher requirements are placed on the control accuracy and response speed of pneumatic actuators and solenoid valves, requiring further strengthening of technological research and development to improve the performance of the equipment.

[0039] In terms of maintenance, although the maintenance cost of pneumatic actuators and solenoid valves for gas valves is relatively low, regular maintenance and upkeep are still indispensable. Regularly checking whether the air pressure of the pneumatic actuator is normal and whether the sealing performance is good, and whether the solenoid coil of the solenoid valve is working properly and whether the valve core is flexible, can help to detect potential faults in time and ensure that the equipment is always in good working condition. At the same time, strengthening the training of maintenance personnel and improving their professional skills and operating level are also important measures to ensure the quality of equipment maintenance.

[0040] In conclusion, pneumatic actuators and solenoid valves, as core components of automatic control in gas systems, play a crucial role in ensuring the safe and efficient operation of these systems. Through precise control and reliable operation, they effectively manage gas flow, ensuring the safe delivery and rational use of gas in urban pipelines and industrial equipment. With continuous technological advancements and innovations, it is believed that pneumatic actuators and solenoid valves will play an even more important role in future gas systems, providing a more solid guarantee for urban development and industrial progress. We should also continuously strengthen the research and application of these two types of equipment, continuously improve their performance to adapt to the ever-changing demands and safety requirements of the gas market, and promote the healthy and sustainable development of the gas industry.

[0041] Please see Figures 1-5 This utility model provides an embodiment of a remote control valve, including a remote solenoid valve body 1; it also includes a vertical slot 15 and an arc-shaped clamping plate 17. Two supporting vertical plates 13 are fixedly connected to the top of the remote solenoid valve body 1, and a positioning plate 14 is fixedly connected between the two supporting vertical plates 13. A vertical slot 15 is provided on the front side of the positioning plate 14. Two telescopic rods 16 are fixedly connected to the side of each of the two supporting vertical plates 13 closest to the positioning plate 14. An arc-shaped clamping plate 17 is fixedly connected to the end of each telescopic rod 16 away from the supporting vertical plates 13. A pipe limiting mechanism is provided on the remote solenoid valve body 1, which is used to position and store the air pipe. An air inlet / outlet mechanism is provided to receive and release air. By pulling the two arc-shaped clamps 17, they are separated. At this time, the telescopic rod 16 and the spring 222 are compressed and contracted. Then, the air tube is placed between the two arc-shaped clamps 17. After that, the two arc-shaped clamps 17 are released, and the two reset plates 221 are pushed closer to each other by the thrust of the spring 222. The reset plates 221 drive the telescopic rod 16 to extend until the two telescopic rods 16 drive the two arc-shaped clamps 17 to clamp the air tube. Finally, the middle section of the air tube that is not clamped is inserted into the vertical slot 15. This restricts the position of the air tube and realizes the function of limiting the air tube.

[0042] Please see Figures 2-5In this embodiment, the tube limiting mechanism includes a storage component and a reset component. The storage component is used to store the trachea, and the reset component is used to keep the two clamps in a clamping state. The storage component and the reset component combine to form a complete tube limiting mechanism. The two cooperate with each other to position and store the trachea. The storage component includes a serpentine slot 211 opened on the front side of the positioning plate 14. The serpentine slot 211 has the same axis specification as the vertical slot 15. When the length of the trachea is too long, the trachea is coiled into a serpentine shape and then inserted into the serpentine slot. The inside of the slot 211 allows the trachea to be stored. The reset assembly includes a reset plate 221 fixed to the outside of the telescopic end of the telescopic rod 16 and a spring 222 fixed to the side of the reset plate 221 away from the arc-shaped clamp 17. The end of the spring 222 away from the reset plate 221 is fixedly connected to the support vertical plate 13. The two reset plates 221 are pushed closer to each other by the thrust of the spring 222. The reset plate 221 then drives the telescopic rod 16 to extend until the two telescopic rods 16 push the two arc-shaped clamps 17 together to clamp the trachea.

[0043] Please see Figures 1-5 In this embodiment, the air intake / exhaust mechanism includes an intake component and an exhaust component. The intake component receives air from the remote solenoid valve body 1, and the exhaust component discharges the received air. The intake and exhaust components together form a complete air intake / exhaust mechanism, which cooperate to receive and release air. The intake component includes an intake port 311 fixed to the top of the remote solenoid valve body 1, two exhaust ports 312 fixed to the top of the remote solenoid valve body 1, and two wooden plugs 313 fixed inside the two exhaust ports 312. The air source pipeline is connected to the intake port 311. A signal is sent to the external 4G antenna of the actuator via an external PC or mobile terminal. After receiving the signal, the external 4G antenna of the actuator transmits the signal to the control board inside the actuator. The control board receives... Upon receiving a signal, the remote solenoid valve body 1 is controlled to operate. At this time, the B outlet 322 is in an unobstructed state. Gas is delivered to the remote solenoid valve body 1 through the inlet 311 via an external gas source. The gas outlet assembly includes an A outlet 321 fixed to the bottom of the remote solenoid valve body 1 and a B outlet 322 fixed to the bottom of the remote solenoid valve body 1. After the gas enters the interior of the remote solenoid valve body 1, it is discharged through the B outlet 322. When the remote solenoid valve body 1 stops working, the A outlet 321 opens. At this time, the A outlet 321 is in an unobstructed state, and the gas inside the remote solenoid valve body 1 is discharged from the A outlet 321. A terminal housing 11 is fixedly connected to the bottom of the remote solenoid valve body 1, and a wiring port 12 is fixedly connected to the right side of the terminal housing 11.

[0044] During operation, the two arc-shaped clamps 17 are first pulled apart, causing the telescopic rod 16 and spring 222 to contract under pressure. The air tube is then placed between the separated arc-shaped clamps 17. The clamps 17 are then released, and the spring 222 pushes the two reset discs 221 closer together. The reset discs 221 then extend the telescopic rod 16 until the two telescopic rods 16 push the two arc-shaped clamps 17 together to hold the air tube. Finally, the unclamped middle section of the air tube is inserted into the vertical slot 15 to restrict its position. The air tube is then connected to the air inlet 311, and the air source pipe is connected to the air inlet 311. The connection is established, and then a signal is sent to the external 4G antenna of the actuator via an external PC or mobile device. After receiving the signal, the external 4G antenna of the actuator transmits the signal to the control board inside the actuator. After receiving the signal, the control board controls the remote solenoid valve body 1 to work. At this time, the B outlet 322 is in a free state. Gas is delivered to the remote solenoid valve body 1 through the inlet 311 through an external gas source. After the gas enters the interior of the remote solenoid valve body 1, it is discharged through the B outlet 322. When the remote solenoid valve body 1 stops working, the A outlet 321 opens. At this time, the A outlet 321 is in a free state, and the gas inside the remote solenoid valve body 1 is discharged from the A outlet 321.

[0045] Through the above steps, by pulling the two arc-shaped clamps 17 to separate them, the telescopic rod 16 and the spring 222 are compressed and contracted. The air tube is placed between the two separated arc-shaped clamps 17 and the arc-shaped clamps 17 are released. The spring 222 pushes the two reset plates 221 closer to each other. The reset plates 221 drive the telescopic rod 16 to extend, so that the arc-shaped clamps 17 clamp the air tube. Finally, the middle section of the air tube is inserted into the vertical slot 15 to limit the position, realizing the air tube limiting function. This solves the problem that common remote control valves can only control the opening and closing of the solenoid valve through a remote PC or mobile terminal, but lack the air tube limiting function. When the air source supplies air to the solenoid valve through the air tube, the gas impact force will cause the air tube to swing irregularly. Long-term use will loosen the connection between the air inlet of the solenoid valve and the air tube, affecting the air supply.
