[0002] In terms of electrical components, the commonly used ordinary solenoid valves are prone to becoming potential fire hazards and causing serious safety accidents once they encounter abnormal voltage increase or excessive current due to their design limitations and manufacturing process deficiencies. Therefore, they cannot be used underground in mines.

[0003] Furthermore, there are a wide variety of underground mining vehicles, and the areas and requirements for protection are different for each. The single-bottle group fire extinguishing equipment on the current market has limited fire extinguishing ability and coverage, and it is difficult to meet diverse needs. If the problem is simply solved by adding multiple sets of fire extinguishing equipment, it will not only occupy a large amount of precious installation space, limit the flexibility and practicality of the vehicle, but also greatly increase the labor input and overall cost.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop an intrinsically safe electromagnetic pilot valve for an electronic automatic fire extinguishing device. Content of the Utility Model

Detailed implementation manners

[0024] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will further describe the present invention in detail in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by showing examples of the present invention.

[0025] As Figure 1-8As shown in the figure, the utility model provides a technical solution for an intrinsically safe electromagnetic pilot valve for an electronic automatic fire extinguishing device: including an electromagnetic pilot valve 2, to which a plurality of charging pipelines 3 are connected. Convenient charging switches 4 are respectively installed on these pipelines to flexibly control the air flow. The end of the charging pipeline 3 is seamlessly butted with the medicine bottle valve body 5. This valve body is not only tightly connected to the medicine bottle 7, which is a container for storing medicine, but also ensures the smooth flow of medicine through the medicine pipe 6. At the top of the electromagnetic pilot valve 2, a 12V power supply connector 1 is specially set to provide stable energy support for the operation of the entire system.

[0026] The electromagnetic pilot valve 2 is carefully constructed from three core components: a main control valve body 10, an electromagnetic driver 12, and a valve body 13. The design of the main control valve body 10 is ingenious. It is not only equipped with a joint body 8 for connecting external devices, but also a exhaust end 9 is cleverly configured obliquely below it to achieve efficient exhaust of air flow. At the same time, an intake end 11 is also equipped on the side of the main control valve body 10. Similarly, a exhaust end 9 is also provided obliquely below it to ensure unobstructed gas flow. At the top of the main control valve body 10, a main control valve core 14 is precisely installed to control the on-off state of the valve. At its bottom, an internal hexagonal plug 18 and a exhaust end 9 are designed to further enhance the sealing and stability of the system.

[0027] The inside of the main control valve body 10 is provided with an intake hole 1001, an exhaust hole 1002, an output hole one 1003, and an output hole two 1004. These holes cooperate with each other to ensure the precise distribution and control of gas. In addition, fixing holes 19 are provided at the edge of the main control valve body 10 to facilitate the stable connection with other components.

[0028] The electromagnetic driver 12, as the control core, is equipped with a wiring terminal 17 at its top to facilitate connection with the external circuit. At the same time, a button seat 15 is designed at the edge to provide an intuitive operation interface for users. The internal structure of the electromagnetic driver 12 is also exquisitely designed. The thimble 1201, as a key component, is tightly wrapped by a coil 1203 on the outside to achieve rapid response through electromagnetic action. Adjacent to the thimble 1201 is an electronic control block 1202, which is responsible for precisely controlling the operation of the electromagnetic driver 12. An internal hexagonal bolt 16 is also equipped at the edge of the electromagnetic driver 12 to ensure its tight connection with the main control valve body 10.

[0029] The valve body 13 serves as a key passage for gas flow. An air inlet 1301, an air outlet 1302, a first output port 1303, and a second output port 1304 are provided on its exterior, and these interfaces maintain the orderly flow of gas. Inside the valve body 13, a groove 1305 is designed to accommodate and guide the gas flow. A paddle 1306 is specifically arranged within the groove 1305, and this paddle is connected to a first valve core 1307, a second valve core 1308, and a valve seat 1309 through a valve core push rod 1311. A spring 1310 is installed at the bottom end of the valve core push rod 1311, providing the necessary elastic support for the opening and closing of the valve core. In addition, an air inlet passage 1312 and an air outlet passage 1313 are provided inside the valve body 13 to ensure the smooth flow of gas.

[0030] In the event of a power interruption, the charging pipeline 3 injects high-pressure gas via the connected charging switch 4. This high-pressure gas first passes through the air inlet end 11 of the main control valve body 10, then enters the main control valve core 14. Subsequently, it smoothly enters the air inlet passage 1312 of the valve body 13 through the air inlet hole 1001 on the side wall of the main control valve body 10 and the air inlet 1301 of the valve body 13, further filling the second valve core 1308. Finally, the high-pressure gas passes through the first output port 1303 and the second output port 1304 of the valve body 13, respectively surging into the first output hole 1003 and the second output hole 1004 of the main control valve body 10, forming an efficient gas flow. During this process, the bottom of the main control valve core 14 remains in a normally closed state under the action of the high-pressure gas, ensuring the stability and safety of the system.

[0031] When the electromagnetic driver 12 receives the power supply from the 12V power supply connector 1. The coil 1203 generates a strong magnetic force under the action of the current, and this magnetic force pushes the push rod 1201 in the electronic control block 1202 to move downward. The push rod 1201 contacts one end of the paddle 1306. Using the lever principle, the valve core push rod 1311 also moves downward accordingly, and at the same time, the spring 1310 is compressed, storing potential energy. At this time, the high-pressure gas directly acts on the top of the main control valve core 14 through the air outlet passage 1313, the air outlet 1302, and the air outlet hole 1002, resulting in a sudden decrease in the upper pressure. Driven by the potential energy released by the spring 1310, the main control valve core 14 moves upward, achieving the transformation from normally closed to normally open. Finally, the excess gas is smoothly discharged through the air outlet end 9, completing the entire gas control process.

[0032] The working principle and usage process of the present utility model: After the present utility model is installed, it works according to the above implementation manner until all working steps are completed.
