When it is necessary to open the solenoid valve coil 16 to activate the spray system, power can be supplied to the solenoid valve coil 16 and compressed gas can be injected into the filter 17 through the compressed gas supply device. When the compressed airflow is energized, the solenoid valve coil 16 drives the solenoid valve piston rod 13 to slide along the solenoid valve body 1, causing the solenoid valve core 14 to slide out of the air chamber, thus connecting the solenoid valve body 1, filter 17, and mechanical valve body 12. The airflow passes through the filter plate 19 in the filter 17 and is filtered and impurities are removed. The purified airflow then passes through the solenoid valve body 1 and enters the mechanical valve body 12 through a pipe.

[0029] As shown in Figure 2 and Figure 4 As shown, a plurality of drying boxes 4 are arranged in the filter 17; the drying boxes 4 are used for drying the compressed airflow; by arranging the drying boxes 4, the drying agent stored in the drying boxes 4 can dry the compressed airflow, so as to reduce the humidity and moisture in the airflow, prevent the internal parts of the electromagnetic valve body 1 and the mechanical valve body 12 from being corroded and rusted due to the increase of humidity, and prolong the service life.
[0030] As shown in Figure 2As shown, the top of the inner wall of the mechanical valve body 12 is fixed with a third spring 5; the bottom of the third spring 5 is fixed with a mechanical valve block 52; a plurality of exhaust holes 53 are arranged on the surface of the mechanical valve body 12; the bottom of the mechanical valve block 52 is fixed with a mechanical piston rod 54; the mechanical piston rod 54 and the mechanical valve body 12 are in sliding fit; the bottom of the mechanical piston rod 54 is fixed with a mechanical valve core 55; the mechanical valve core 55 and the electromagnetic valve coil 16 are in sliding fit; after the compressed gas flow enters the inside of the mechanical valve body 12, the pressure in the cavity formed between the mechanical valve block 52 and the mechanical valve core 55 will increase, the mechanical valve block 52 will be lifted under the action of the gas pressure and the third spring 5 will be in a compressed state, in the process, the mechanical valve block 52 will pass through the exhaust hole 53, at this time, the compressed gas flow can be discharged from the exhaust hole 53, and in the process of lifting of the mechanical valve block 52, the mechanical valve core 55 will slide along the electromagnetic valve coil 16, so that the pipeline in the electromagnetic valve coil 16 is in a communication state, so that the water flow can flow in the electromagnetic valve coil 16.
[0031] As shown in Figure 1 and Figure 5 As shown, the outer wall of the electromagnetic valve coil 16 is fixed with a plurality of fins 6; the outer wall of the fin 6 is arranged in a wave shape and is arranged in an inclined manner; by arranging the fin 6, a large amount of heat will be generated on the surface of the electromagnetic valve coil 16 when it works for a long time, and these heat can be transferred to the fin 6, the fin 6 can increase the contact area of the heat with the outside air to speed up the evaporation speed and speed up the heat dissipation work of the electromagnetic valve coil 16, since the fin 6 is in a wave shape, the heat exchange area with the air can be increased, and since the fin 6 is arranged in an inclined manner, some particles adhered to the surface of the fin 6 will slide out under the action of gravity, reducing the impurities remaining on the surface of the fin 6.
[0032] As shown in Figure 5 As shown, the outer wall of the fin 6 is fixed with a plurality of spherical protrusions 7; the spherical protrusions 7 are arranged in a filling manner; by arranging the spherical protrusions 7, the heat exchange area between the fin 6 and the air can be further increased, and the heat dissipation effect of the fin 6 on the electromagnetic valve coil 16 can be improved.
[0033] As shown in Figure 5 As shown, the fin 6 and the electromagnetic valve coil 16 can be bonded by epoxy heat conductive adhesive; compared with welding and bolt connection, the connection gap between the fin 6 and the electromagnetic valve coil 16 can be reduced by bonding the fin 6 and the electromagnetic valve coil 16 by epoxy heat conductive adhesive, the heat conduction path between the fin 6 and the electromagnetic valve coil 16 is further increased, so that the heat can be quickly transferred from the electromagnetic valve coil 16 to the surface of the fin 6.
[0034] Working principle: when the electromagnetic valve coil 16 needs to be opened to open the sprinkler system, compressed gas can be injected into the filter 17 by supplying power to the electromagnetic valve coil 16 and supplying compressed gas to the filter 17. After the electromagnetic valve coil 16 is energized, the electromagnetic valve piston rod 13 will slide along the electromagnetic valve body 1, and the electromagnetic valve spool 14 will slide out of the air chamber to make the electromagnetic valve body 1, the filter 17 and the mechanical valve body 12 communicate. The gas flow will pass through the filter plate 19 in the filter 17 and be filtered out, and then the filtered gas flow will pass through the electromagnetic valve body 1 and enter the mechanical valve body 12 through the pipeline. The compressed gas flow can drive the mechanical valve body 12 to an open state, and the electromagnetic valve coil 16 is in an open state. At this time, the water flow can flow in the electromagnetic valve coil 16. When the filter plate 19 works for a long time, it needs to be replaced. At this time, the second spring 22 can be compressed by pressing a pair of connecting plates 2, and the connecting plate 2 will slide out of the groove with the lug, so that the cover plate 18 is in a movable state. Then the cover plate 18 can be removed from the surface of the filter 17, and the filter plate 19 can be removed from the installation slot 110 for replacement or cleaning. By setting the positioning groove 3 and the clamping block 32, the new filter plate 19 is replaced in the installation slot 110. The angle of the filter plate 19 can be adjusted so that one positioning groove 3 on its surface corresponds to the clamping block 32 on the bottom of the cover plate 18. When the cover plate 18 is installed on the surface of the filter 17, the clamping block 32 will also be clamped into the positioning groove 3. Because the edge of the positioning groove 3 is inclined, the connection between the clamping block 32 and the positioning groove 3 is more stable and accurate, so as to provide additional fixation for the filter plate 19 during work and reduce its shaking and deflection caused by excessive gas flow. By setting the drying box 4, the desiccant stored in the drying box 4 can dry the compressed gas flow to reduce the moisture in the gas flow and ensure that the internal parts of the electromagnetic valve body 1 and the mechanical valve body 12 will not be corroded and rusted due to increased humidity, prolonging their service life. After the compressed gas flow enters the mechanical valve body 12, the pressure in the chamber between the mechanical valve block 52 and the mechanical valve core 55 will increase, and the mechanical valve block 52 will be lifted under the action of gas pressure and the third spring 5 will be in a compressed state. During this process, the mechanical valve block 52 will pass through the exhaust hole 53, and at this time the compressed gas flow can be discharged from the exhaust hole 53, and the mechanical valve core 55 will slide along the electromagnetic valve coil 16 during the lifting process of the mechanical valve block 52 to make the pipeline in the electromagnetic valve coil 16 communicate, so that the water flow can flow in the electromagnetic valve coil 16. By setting the fin 6, a large amount of heat will be generated on the surface of the electromagnetic valve coil 16 when it works for a long time. These heat can be transferred to the fin 6, which will increase the contact area of these heat with the outside air to speed up the evaporation speed and accelerate the heat dissipation of the electromagnetic valve coil 16. Because the fin 6 is in a wave shape, it can increase the heat exchange area with the air. At the same time, because the fin 6 is inclined, some particles adhering to the surface of the fin 6 will slide out under the action of gravity, reducing the residual impurities on the surface of the fin 6.By setting the spherical protrusion 7, the spherical protrusion 7 can further increase the heat exchange area between the fin 6 and the air, improve the heat dissipation effect of the fin 6 on the electromagnetic valve coil 16; the fin 6 and the electromagnetic valve coil 16 are bonded by the epoxy resin heat-conducting glue, compared with welding and bolt connection, the connecting gap between the fin 6 and the electromagnetic valve coil 16 can be reduced, the heat-conducting path between the fin 6 and the electromagnetic valve coil 16 is further increased, so that the heat can be quickly transmitted from the electromagnetic valve coil 16 to the surface of the fin 6.

Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
