Detailed Implementation
[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.
[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a flame-retardant and wear-resistant fire hose, including a hose body 1, a connector 2 on the hose body 1, the connector 2 being connected to a fire hydrant, the hose body 1 being used to transport water or other fire extinguishing media, a protective structure 3 on the hose body 1, and a sealing structure 4 on the connector 2.
[0023] Please see Figure 3 and Figure 4This utility model provides a flame-retardant and wear-resistant fire hose. The protective structure 3 includes a bottom layer 31, which is bonded to the surface of the hose body 1 by a composite layer 35, so that the protective structure 3 is better fixed to the surface of the hose body 1. A protective layer 32 is provided on the surface of the bottom layer 31. The protective layer 32 is made of aramid fiber and wraps around the surface of the bottom layer 31. The aramid fiber used in the protective layer 32 has the effects of wear resistance, high temperature resistance, impact resistance and puncture resistance, which improves the wear resistance and puncture resistance of the hose body 1. A flame-retardant layer 33 is provided on the surface of the protective layer 32. The flame-retardant layer 33 is a flame-retardant coating applied to the surface of the protective layer 32, and a coating with wear-resistant particles is added to the flame-retardant coating, so that the hose body 1 has better flame-retardant effect and wear resistance.
[0024] Among them, a tensile layer 34 is provided between the protective layer 32 and the bottom layer 31. The tensile layer 34 is made of nylon and has tear resistance, which improves the tensile and tear resistance of the water hose body 1.
[0025] Please see Figure 3 and Figure 5 This utility model provides a flame-retardant and wear-resistant fire hose. The sealing structure 4 includes a mating interface 41. The connector 2 has a mating interface 41. A plug ring 42 is inserted into the mating interface 41. A sealing gasket 43 is integrally formed on the plug ring 42. A positioning ring 44 is fixed in the plug ring 42. A bayonet 45 is provided on the positioning ring 44. A locking ring 46 is provided on the inner side of the mating interface 41. There are two locking rings 46, which have a better locking effect on the plug ring 42.
[0026] A positioning rod 47 is provided inside the interface 41, and the positioning ring 44 can be inserted into the positioning rod 47, which can effectively prevent the phenomenon of rotation and twisting caused by torque.
[0027] Specifically, the insert ring 42 is inserted into the interface 41, and then the locking ring 46 squeezes the insert ring 42 and locks it into the slot 45, thereby positioning the insert ring 42. Compared with the existing assembled sealing ring, it has a more stable installation effect and is less prone to loosening and positional displacement. This ensures that the sealing gasket 43 is properly aligned and less prone to displacement when the joint 2 is mated, resulting in a better sealing effect. When the insert ring 42 is inserted into the interface 41, the positioning ring 44 mates with the positioning rod 47, so that the sealing gasket 43 will not rotate or twist when the joint 2 is twisted and mated.
