Technical Field

[0001] This utility model relates to the field of gas source equipment technology, and in particular to an integrated valve for controlling gas sources. Background Technology

[0002] A gas source refers to the source of gas used in various equipment and systems, including fuel gas and compressed air. These gases can be natural gas, liquefied petroleum gas, manufactured gas, etc., used for daily needs such as heating and cooking. In the industrial and technological fields, gas sources also include compressed air, used for the power and control systems of automated systems.

[0003] In situations where a small amount of gas is needed, the gas source is usually filled inside the gas cylinder. However, when using the gas cylinder, components such as safety valves, gas regulating valves, and control valves are required. Connecting these components one by one to the gas cylinder makes the entire operation of using the gas cylinder quite cumbersome and affects the efficiency of using the gas cylinder. Therefore, an integrated valve for controlling the gas source is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an integrated control valve for air supply to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an integrated control gas source valve, including a valve island. A sensor interface is provided on one side of the valve island, with a temperature and pressure sensor connected to one sensor interface and a pressure sensor connected to the other. An electromagnetic inflation valve interface is provided on the side of the valve island away from the sensor interface, with an electromagnetic inflation valve connected to it. Connection ports are provided on two symmetrical sides of the valve island, each connected to a ejector. Gas cylinder interfaces are provided in the middle of the two symmetrical sides of the valve island, each connected to a gas cylinder. A solenoid valve interface is provided on one side of the valve island, with a solenoid valve at one end and an electromagnetic pressure relief valve. A safety valve interface is provided on the side of the valve island away from the solenoid valve interface, with a safety valve connected to it. Two regulating valve interfaces are provided on the side of the valve island adjacent to the safety valve, each connected to a regulating valve.

[0007] Preferably, as described in any of the above schemes, a signal indicator light is provided on the side of the valve island adjacent to the safety valve.

[0008] Preferably, in any of the above solutions, the electromagnetic inflation valve is connected to an external pipeline.

[0009] Preferably, in any of the above schemes, the safety valve interface corresponds to the position of the solenoid valve structure, the solenoid inflation valve interface corresponds to the position of a sensor interface, and the temperature and pressure sensor is located above the pressure sensor.

[0010] Preferably, of any of the above schemes, the gas regulating valve is an electromagnetic regulating valve with a position signal, and the two gas regulating valve interfaces are symmetrically distributed on one side of the valve island.

[0011] Preferably, the capacity of the gas cylinder is 100-600ml, which is one of the above-mentioned options.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. This integrated control gas source valve integrates the temperature and pressure sensors, pressure sensors, electromagnetic filling valve, ejector, solenoid valve, electromagnetic pressure relief valve, safety valve, and gas regulating valve required for gas cylinder operation on the valve island. When the gas cylinder needs to be used, it can be simply connected to the valve island, which simplifies the operation of the gas cylinder and improves the efficiency of gas cylinder use. Furthermore, the integrated installation of the temperature and pressure sensors, pressure sensors, electromagnetic filling valve, ejector, solenoid valve, electromagnetic pressure relief valve, safety valve, and gas regulating valve on the valve island saves space, reduces the overall size and weight of the integrated control gas source valve, and facilitates transportation.

[0014] 2. This integrated control valve can monitor the pressure and temperature of the gas cylinder, regulate the flow rate, and depressurize the gas cylinder. This multi-functionality enhances the safety of gas cylinder use and improves its practicality. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0021] like Figures 1 to 4 As shown, an integrated valve for controlling a gas source includes a valve island 1. A sensor interface 2 is located on one side of the valve island 1. One sensor interface 2 is connected to a temperature and pressure sensor 3, and the other sensor interface 2 is connected to a pressure sensor 4. The temperature and pressure sensors 3 and 4 can measure the gas source and temperature of the gas cylinder during operation. An electromagnetic filling valve interface 5 is located on the side of the valve island 1 away from the sensor interface 2, and an electromagnetic filling valve 6 is connected to the electromagnetic filling valve interface 5. Connection ports 7 are located on two symmetrical sides of the valve island 1, and ejector tubes 8 are connected to both connection ports 7. The ejector tubes 8 are used for compressed air; the gas flow rate is controlled by controlling the amount of compressed air entering the ejector tubes 8. Gas cylinder interfaces 9 are located in the middle of the two symmetrical sides of the valve island 1, and gas cylinders 10 are connected to both gas cylinder interfaces 9. An electromagnetic filling valve 6 is located on one side of the valve island 1. The valve interface 11 has a solenoid valve 12 at one end and a solenoid pressure relief valve 13 on it. The solenoid pressure relief valve 13 can reduce the pressure of the gas during transportation. A safety valve interface 14 is located on the side of the valve island 1 away from the solenoid valve interface 11, and a safety valve 15 is located on the safety valve interface 14. Two gas regulating valve interfaces 16 are located on the side of the valve island 1 adjacent to the safety valve 15. Each of the two gas regulating valve interfaces 16 is connected to a gas regulating valve 17. The gas regulating valve 17 can regulate the flow rate and pressure of the gas. In cooperation with the solenoid pressure relief valve 13, it can prevent the pressure from being too high during the transportation of gas, thus enabling more stable gas transportation. The temperature and pressure sensor 3, pressure sensor 4, solenoid valve 12, solenoid pressure relief valve 13, safety valve 15 and gas regulating valve 17 are all connected to an external control system.

[0022] As an optional technical solution of this utility model, a signal indicator light 18 is provided on the side of the valve island 1 adjacent to the safety valve 15. The signal indicator light 18 is connected to the control system. When the control air source integrated valve is working, the signal indicator light 18 will light up, thereby reminding the personnel that the control air source integrated valve is being used.

[0023] As an optional technical solution of this utility model, the electromagnetic air valve 6 is connected to an external pipeline, thereby providing an air source to the external pipeline.

[0024] As an optional technical solution of this utility model, the safety valve interface 14 corresponds to the position of the solenoid valve structure 11, the electromagnetic inflation valve interface corresponds to the position of a sensor interface 2, and the temperature and pressure sensor 3 is located above the pressure sensor 4, so as to more accurately measure the temperature and pressure of the gas output to the external pipeline.

[0025] As an optional technical solution of this utility model, the gas regulating valve 17 is an electromagnetic regulating valve with a position signal. The two gas regulating valve interfaces 16 are symmetrically distributed on one side of the valve island 1. The gas regulating valve 17 has a position signal so that the control system can receive and process the signals from the temperature and pressure sensor 3 and the pressure sensor 4, and then control the solenoid valve 12, the solenoid pressure relief valve 13, the safety valve 15 and the gas regulating valve 17 through electrical signals, drive the valve core to open and close and adjust its position, thereby achieving precise control of gas flow and pressure.

[0026] As an optional technical solution of this utility model, the capacity of the gas cylinder 10 is 100-600ml, and the 100-600ml gas cylinder is a common specification of gas cylinder.

[0027] An integrated valve for controlling air supply operates on the following principle:

[0028] In use, connect gas cylinder 10 to gas cylinder interface 9 and connect electromagnetic filling valve 6 to external pipeline. The control system receives and processes signals from temperature and pressure sensor 3 and pressure sensor 4, and then controls electromagnetic valve 12, electromagnetic pressure relief valve 13, safety valve 15 and gas regulating valve 17 through electrical signals to drive the opening and closing and position adjustment of valve core, thereby realizing the control of gas flow and pressure.

[0029] In summary, this integrated control valve for the gas source ensures that the temperature and pressure sensor 3, pressure sensor 4, electromagnetic filling valve 6, ejector 8, solenoid valve 12, electromagnetic pressure relief valve 13, safety valve 15, and regulating valve 17 required for the operation of gas cylinder 10 are installed on valve island 1. When gas cylinder 10 needs to be used, it only needs to be connected to valve island 1, thus simplifying the operation of gas cylinder 10 and improving its efficiency. Furthermore, the temperature and pressure sensor 3, pressure sensor 4, electromagnetic filling valve 6, ejector 8, solenoid valve 12, and electromagnetic pressure relief valve are all integrated into the valve island 1. 13. The safety valve 15 and the gas regulating valve 17 are integrated and installed on the valve island 1, which saves space, reduces the overall volume and weight of the integrated control gas source valve, and facilitates transportation. The integrated control gas source valve can monitor the pressure and temperature of the gas cylinder 10, regulate the flow rate of the gas cylinder 10, and depressurize the gas cylinder 10. This makes the integrated control gas source valve more functional, making the use of the gas cylinder 10 safer and improving its practicality.
