Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The following is combined with Figure 1-5 To further explain this application in detail,
[0024] The present application embodiment discloses a corrosion-resistant high-pressure hose. Figure 1 , Figure 2 , Figure 3 and Figure 4 A corrosion-resistant high-pressure hose comprises a high-pressure hose body 1, a threaded connector 2 is fixedly mounted on one end of the high-pressure hose body 1, a butt joint 3 is fixedly mounted on the other end of the high-pressure hose body 1, and an anti-drop mechanism 4 is arranged on the surface of the threaded connector 2;
[0025] The anti-falling mechanism 4 includes a docking plate 401, which is fixedly installed on one side of the threaded connector 2. The inner wall of the docking plate 401 is connected to a docking rod 402, and one end of the docking rod 402 is fixedly installed with a limiting plate 403. A rotating groove 404 is provided on the surface of the docking head 3, and the inner cavity of the rotating groove 404 is rotatably connected to a fixed plate 405. A connecting groove 406 is provided on the top of the fixed plate 405. The surface of the docking rod 402 is rotatably connected to the inner cavity of the connecting groove 406. A fixing groove 407 is provided on the inner wall of the connecting groove 406. The inner cavity of the fixing groove 407 is slidably connected to the surface of the limiting plate 403.
[0026] Reference Figure 4, a stop groove 5 is provided at the bottom of the docking plate 401, and a stop block 6 is fixedly installed on the surface of the docking rod 402. The surface of the stop block 6 is slidably connected to the inner cavity of the stop groove 5. The sliding connection between the stop groove 5 and the stop block 6 can limit the moving distance of the docking rod 402. The docking rod 402 is threadedly connected to the docking block. When the top of the stop block 6 contacts the inner wall of the stop groove 5, the bottom limit plate 403 can be rotated 180°, so that the limit plate 403 is rotated out of the inner cavity of the fixed groove 407, and the separation between the fixed groove 407 and the limit plate 403 is completed. When the docking rod 402 contacts the top of the docking plate 401, the limit plate 403 can contact the inner wall of the fixed groove 407, and the position of the fixed plate 405 and the docking plate 401 is fixed;
[0027] Reference Figure 3 A sealing ring 7 is fixedly installed on the inner wall of the butt joint 3, and the surface of the sealing ring 7 is in close contact with the surface of the threaded connector 2. By setting the sealing ring 7 and threading the threaded connector 2 with the inner wall of the butt joint 3, the sealing between the two high-pressure hose bodies 1 is achieved. During the sealing process, the top of the threaded connector 2 will contact the sealing ring 7 on the inner wall of the butt joint 3, which can further increase the sealing performance of the two after docking;
[0028] Reference Figure 5 The high-pressure hose body 1 includes a base layer 8, a reinforcing layer 9 is bonded to the surface of the base layer 8, a heat-insulating layer 10 is bonded to the surface of the reinforcing layer 9, a supporting layer 11 is bonded to the surface of the heat-insulating layer 10, a fire-proof layer 12 is bonded to the surface of the supporting layer 11, and a wear-resistant layer 13 is bonded to the surface of the fire-proof layer 12. By setting the reinforcing layer 9, the reinforcing layer 9 is bonded to the surface of the base layer 8 to increase the strength and pressure resistance of the high-pressure hose body 1, and the pressure-bearing capacity of the high-pressure hose body 1 can be effectively improved. By setting the heat-insulating layer 10, the high-temperature resistance of the high-pressure hose body 1 can be improved, so that the structural integrity and functional stability can be maintained in a high-temperature environment. By setting the supporting layer 11, support can be provided to the fire-proof layer 12 to keep it flat and stable. By setting the fire-proof layer 12, the high-pressure hose body 1 can be prevented from being ignited or burned in extreme situations such as fire, thereby improving the safety performance of the high-pressure hose body 1. By setting the wear-resistant layer 13, which is bonded to the outermost layer, it can effectively resist wear and scratching, and extend the service life of the high-pressure hose body 1.
[0029] Reference Figure 5The reinforcing layer 9 is made of aramid fiber, and the heat insulating layer 10 is made of ceramic fiber. The reinforcing layer 9 is made of aramid fiber. The use of aramid fiber as a reinforcing layer to replace steel wire can reduce product weight, increase working pressure, enhance fatigue resistance and prevent rust. The heat insulating layer 10 is made of ceramic fiber. Ceramic fiber is a high-performance refractory material with excellent high temperature resistance, oxidation resistance and heat insulation performance. It can be used for a long time at extremely high temperatures without damage;
[0030] Reference Figure 5 The support layer 11 is made of nylon fiber, and the fireproof layer 12 is made of glass fiber. The support layer 11 made of nylon fiber has good strength, which can enhance the durability and stability of the high-pressure hose body 1. The fireproof layer 12 made of glass fiber has good high temperature resistance and chemical stability, and can be used as a reinforcing material for the fireproof layer 12 to improve the fire resistance limit of the high-pressure hose body 1.
[0031] Reference Figure 5 The wear-resistant layer 13 is made of polytetrafluoroethylene. The wear-resistant layer 13 made of polytetrafluoroethylene is a material with a low friction coefficient and excellent wear resistance and corrosion resistance. It can reduce the friction loss of the high-pressure hose body 1 during movement, improve the wear resistance, and also has good resistance to certain chemical media;
[0032] Working principle: During use, when two high-pressure hose bodies 1 are docked, the threaded connection between the threaded connector 2 and the inner wall of the docking connector 3 is realized, and the sealing between the two high-pressure hose bodies 1 is realized. During the sealing process, the top of the threaded connector 2 will contact the sealing ring 7 on the inner wall of the docking connector 3, which can further increase the sealing after the two are docked. During the docking process, the fixing plate 405 is rotated in the inner cavity of the rotating groove 404, so that the top of the fixing plate 405 can coincide with the bottom of the connecting groove 406, and the docking rod 402 can enter the inner cavity of the connecting groove 406, and the docking rod 402 is rotated. The limiting plate 403 is driven by the docking rod 402 to enter the inner wall of the fixed groove 407, so as to realize the docking between the fixing plate 405 and the docking plate 401, thereby avoiding the detachment phenomenon between the docking connector 3 and the threaded connector 2, and further increasing the stability of the docking connector 3 and the threaded connector 2 after the threaded connection.
[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
