A water inlet pipe 14 is fixedly connected to one end of the cooling shell 12, and a water outlet pipe 15 is fixedly connected to the other end of the cooling shell 12. The pair of outer shells 13 are connected by a connector.

[0024] In use, the inlet pipe 14 is connected to the fire water pipe or the tap water pipe through the pipeline. After the fire water pipe is turned on, the water in the pipe is injected into the cavity 16 inside the cooling shell 12 through the inlet pipe 14, and the water flows out through the outlet pipe 15. By relying on the water flowing in the cavity 16 inside the cooling shell 12, the inside of the solenoid valve body 11 inside the cooling shell 12 can be cooled, thereby improving the high temperature resistance of the solenoid valve body 11. The cooling shell 12 is provided with an outer shell 13 made of heat insulation material to enhance the heat insulation effect.

[0025] Preferably, the outer shell 13 and the cooling shell 12 are provided with cavities 16 for the wiring harness of the solenoid valve body 11, and the internal shape of the cooling shell 12 matches the surface of the solenoid valve body 11, thereby increasing the contact area between the cooling shell 12 and the surface of the solenoid valve body 11.

[0026] Furthermore, such as Figure 1 and 5 As shown, the connector includes a base 22 and a retainer 21. The base 22 and retainer 21 are respectively fixed to the side walls of the two outer shells 13. The side of the base 22 is symmetrically connected to two claws 23. The retainer 21 has a groove 25 at the position corresponding to the claws 23. The end of the claw 23 passes through the groove 25. A spring 24 is fixed between the ends of the two claws 23 away from the retainer 21. A guide rod 31 is fixed to the side of the base 22. The retainer 21 has a through hole 32 at the position corresponding to the guide rod 31. The guide rod 31 passes through the through hole 32. The guide rod 31 and the through hole 32 are slidably connected.

[0027] During installation, the operator aligns the two outer shells 13 and aligns the claws 23 with the slots 25 on the base 21. By pressing and pushing, the outer shells 13 are closed, and the claws 23 enter the slots 25. Under the action of the spring 24, the ends of the claws 23 return to their original position and lock into the base 21, thus connecting the claws 23 and the base 21. The snap-fit ​​connection makes installation convenient for the operator. During installation, the guide rod 31 on the base 22 passes through and is inserted into the through hole 32 on the base 21 to position the two outer shells 13, which facilitates subsequent installation.

[0028] Furthermore, such as Figures 3-4 As shown, a partition 41 is fixedly connected inside the cavity 16, and a plurality of water holes 42 are opened on the top of the partition 41; the partition 41 is located between the water inlet pipe 14 and the water outlet pipe 15; a filter cylinder 51 is fixedly connected to the end of the water inlet pipe 14 away from the cavity 16, and a pipe joint 52 is fixedly connected to the end of the filter cylinder 51 away from the water inlet pipe 14; a filter screen 53 is fixedly connected to the inner side wall of the filter cylinder 51, and the filter screen 53 is arranged in a frustum shape.

In use, a filter cartridge 51 and a pipe connector 52 are installed at the end of the water inlet pipe 14. The pipe connector 52 can be used to easily connect it to the water pipe. A filter screen 53 is installed inside the filter cartridge 51, which can reduce the possibility of impurities in the fire water pipe entering the cavity 16 and causing blockage.

[0030] Furthermore, such as Figure 2 As shown, the surface of the outer shell 13 is provided with a metal shielding layer 61, and a heat insulation layer 62 is provided between the outer shell 13 and the cooling shell 12;

[0031] In use, the metal shielding layer 61 is provided on the outer shell 13 and covers the outside of the solenoid valve body 11, thereby improving the anti-interference performance of the solenoid valve. The heat insulation layer 62 is filled between the outer shell 13 and the cooling shell 12, thereby enhancing the heat insulation effect and improving the high temperature resistance of the solenoid valve.

[0032] Furthermore, such as Figure 5 As shown, the end of the claw 23 near the base 21 is provided with a bevel 7; in use, the end of the claw 23 is provided with a bevel 7, which makes it easy to install and connect the outer shell 13, making it convenient for workers to use.

[0033] Working principle: During use, the inlet pipe 14 is connected to the fire hydrant pipe or tap water pipe. After the fire hydrant pipe is turned on, water in the pipe flows into the cavity 16 inside the cooling shell 12 through the inlet pipe 14, and the water flows out through the outlet pipe 15. The flow of water in the cavity 16 of the cooling shell 12 cools the inside of the solenoid valve body 11, thereby improving the high-temperature resistance of the solenoid valve body 11. The exterior of the cooling shell 12 is made of heat-insulating material. The outer shell 13 enhances heat insulation. During installation, the operator aligns the two outer shells 13 and the locking claws 23 with the locking slots 25 on the locking seat 21. Pressing and pushing the outer shells 13 together causes the locking claws 23 to enter the locking slots 25. Under the action of the spring 24, the ends of the locking claws 23 return to their original position and lock into the locking seat 21, thus connecting the locking claws 23 and the locking seat 21. This snap-fit ​​connection facilitates installation. The guide rod 31 on the base 22 passes through and is inserted into the through hole 32 on the card holder 21 to position the two outer shells 13, which facilitates subsequent installation. A partition 41 is provided inside the cavity 16, and the water hole 42 on the partition 41 is used for water flow. The partition 41 guides the water flow in the cavity 16, improves the uniformity of the flow, and facilitates overall cooling. During use, a filter cartridge 51 and a pipe connector 52 are installed at the end of the water inlet pipe 14. The pipe connector 52 makes it easy to connect to the water pipe. A filter screen 53 is installed inside the filter cartridge 51 to reduce the possibility of impurities in the fire water pipe entering the cavity 16 and causing blockage. A metal shielding layer 61 is provided on the outer shell 13 and covers the outside of the solenoid valve body 11 to improve the anti-interference performance of the solenoid valve. A heat insulation layer 62 is filled between the outer shell 13 and the cooling shell 12 to enhance the heat insulation effect and improve the high temperature resistance of the solenoid valve.
