The pressure-resistant layer includes a pressure-resistant part, one side of the pressure-resistant part abuts against the outer wall of the middle rubber layer, and the other side abuts against the inner wall of the outer rubber layer. The inner rubber layer can withstand the pressure of the medium conveyed inside the hydraulic pipe and protect the external structure. The reinforcement layer increases the strength of the pipeline and ensures the use pressure of the hydraulic pipe. The middle rubber layer plays a transition role between the pressure-resistant layer and the reinforcement layer, and provides a support surface for the pressure-resistant layer and the reinforcement layer. The pressure-resistant layer mainly plays a buffering role against external force and improves the pressure resistance of the hydraulic pipe. The outer rubber layer mainly protects the internal structure from interference from external factors and has the effect of improving the pressure resistance of the hydraulic pipe.

However, once the pressure breaks through the outer layer and directly hits the pressure-resistant layer, under the impact of the pressure, the entire pipe body will be damaged due to the weak pressure resistance of the middle layer, thereby increasing the scrap rate of the hydraulic pipe.

Because the pipe body 1 itself is made of rubber, the rubber and cloth combined hose has good foldability and can be easily transported and used without having a negative impact on the connectivity of the pipeline.
[0028] One layer 21 includes an outer pressure-resistant layer 211 and an outer steel wire mesh 212. The outer pressure-resistant layer 211 is arranged inside the first layer 21, and the outer steel wire mesh 212 is laid between the outer pressure-resistant layer 211 and the reinforcement layer 221. By arranging the outer pressure-resistant layer 211 and the outer flat steel wire 212, and by winding the outer flat steel wire 212 between the outer pressure-resistant layer 211 and the reinforcement layer 221, the outer flat steel wire 212 has the characteristics of high hardness, high elastic modulus, heat resistance, good pressure resistance, etc., especially good resistance to twisting and bending deformation. The hydraulic pipe made of the flat steel wire has much better single-pulse performance, thereby improving the practicability of the device.
[0029] The middle layer 3 includes an airbag 31 and high-pressure gas 32. The airbag 31 is arranged inside the middle layer 3, and the inside of the airbag 31 is provided with high-pressure gas 32. By filling the airbag 31 with high-pressure gas 32, the airbag 31 is expanded in the middle layer 3 to fill the entire middle layer 3. The high-pressure gas 32 improves the pressure resistance of the middle layer 3, thereby improving the practicability of the device.
[0030] An air hole 33 is provided inside the tube body 1, and the air hole 33 is connected to the air bag 31; the high-pressure gas 32 enters the air bag 31 through the air hole 33.

[0032] The inner layer 4 includes an inner pressure-resistant layer 41 and an inner steel wire mesh 42. The inner pressure-resistant layer 41 is arranged inside the inner layer 4, and the inner steel wire mesh 42 is laid inside the inner layer 4 and on the inner side of the inner pressure-resistant layer 41. By arranging the inner pressure-resistant layer 41 and the inner flat steel wire 42, the inner layer 4 of the hydraulic pipe also has a certain pressure resistance performance, the overall pressure resistance of the pipe body 1 is enhanced, and the pressure resistance effect of the hydraulic pipe is further improved, thereby improving the practicability of the device.
[0033] Working principle: By setting an outer pressure-resistant layer 211 and an outer flat steel wire 212, and by winding the outer flat steel wire 212 between the outer pressure-resistant layer 211 and the reinforcing layer 221, the outer flat steel wire 212 has the characteristics of high hardness, high elastic modulus, heat resistance, good pressure resistance, etc., especially good resistance to twisting and bending deformation. The hydraulic pipe made of flat steel wire has much better single pulse performance.
[0034] By setting a reinforcing layer 221 and a high-strength cloth 222, the materials of the high-strength cloth 222 mainly include polyester cloth, nylon cloth, cotton cloth, etc., by using the high-strength cloth 222 to reinforce the layer 221, it can withstand greater pressure and is not prone to safety accidents such as pipe burst and tripping. Because the pipe body 1 itself is made of rubber, the rubber and cloth combined hose has good foldability and can be easily transported and used without having a negative impact on the connectivity of the pipeline.
[0035] By providing the airbag 31, high-pressure gas 32, air holes 33, air plug 34 and sealant 35, the high-pressure gas 32 enters the airbag 31 through the air holes 33, so that the airbag 31 expands in the middle layer 3 and fills the entire middle layer 3. The sealant 35 is used to ensure reliable sealing between the air hole 33 and the air plug 34, thereby ensuring that the high-pressure gas 32 in the airbag 31 is not easy to leak, and ensuring the stability of the high-pressure gas 32 in the airbag 31 during the use of the hydraulic pipe. Therefore, when the outer layer 2 is subjected to pressure, the middle layer 3 as the backbone has a certain pressure resistance, and further, by improving the pressure resistance of the hydraulic pipe, the scrap rate of the hydraulic pipe is reduced.
[0036] By arranging the inner pressure-resistant layer 41 and the inner flat steel wire 42, the inner layer 4 of the hydraulic pipe also has a certain pressure resistance, thereby strengthening the overall pressure resistance of the pipe body 1 and further improving the pressure resistance of the hydraulic pipe.
