[0001] The utility model relates to the technical field of hydraulic rubber hoses, and particularly to a flame-retardant and heat-insulating hydraulic rubber hose structure. Background Art

[0002] Hydraulic rubber hoses, also known as hydraulic oil pipes, hydraulic hoses, high-pressure hoses, hydraulic pipes, steel wire high-pressure pipes, steel wire braided hoses, and steel wire wound hoses, are generally divided into steel wire braided hydraulic hoses and steel wire wound hydraulic hoses. They are commonly used for the transportation of liquid media such as modern petroleum-based liquids and water-based liquids, and need to have high performance in oil resistance, heat resistance, aging resistance, and high pressure bearing capacity.

[0003] In the prior art CN209115826U, a hydraulic rubber hose is proposed, which includes a nylon inner layer, a first steel wire winding layer, a rubber buffer layer, a second steel wire winding layer, a rubber outer layer, and a stainless steel strip winding layer. The thickness of the nylon inner layer is 1 mm to 1.5 mm. Both the first steel wire winding layer and the second steel wire winding layer are spiral winding structures with a spiral angle of 30 degrees to 50 degrees. The thickness of the stainless steel strip of the stainless steel strip winding layer is 2.5 mm to 4 mm, and the stainless steel strip winding layer is a spiral winding structure with a spiral angle of 45 degrees to 65 degrees. It has excellent flame retardancy, and at the same time has good pressure bearing capacity and flex resistance.

[0004] When the prior art is in use, its inner tube is in long-term contact with the conveying medium, subjected to large forces, and eroded by oil for a long time, which will cause the rubber layer to become thinner, thereby reducing the service life of the device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flame-retardant and heat-insulating hydraulic rubber hose structure to solve the problem that in the above-mentioned background art, the inner tube is in long-term contact with the conveying medium, subjected to large forces, and eroded by oil for a long time, which will cause the rubber layer to become thinner, thereby reducing the service life of the device.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a flame-retardant and heat-insulating hydraulic rubber hose structure, including a main body mechanism. The main body mechanism includes a flame-retardant outer tube, an antioxidant coating, a heat-insulating inner tube, a hose inlet, a wear-resistant layer, a first flame-retardant layer, a steel wire winding reinforcement layer, a high-strength limiting braided layer, a second flame-retardant layer, a heat-insulating layer, a buffer layer, and an oil-resistant layer. The antioxidant coating is fixedly arranged at the outer end of the flame-retardant outer tube. The heat-insulating inner tube is fixedly installed at the inner end of the flame-retardant outer tube. The hose inlet is fixedly arranged at the left end of the heat-insulating inner tube.

[0007] Preferably, the wear-resistant layer is fixedly arranged at the outer end of the inner side of the flame-retardant outer tube. The first flame-retardant layer is fixedly arranged at the inner end of the wear-resistant layer.

[0010] Preferably, the antioxidant coating is a silver ion coating, which interferes with the synthesis of the cell wall. The important component of the bacterial cell wall is peptidoglycan. The interference of the silver ion antibacterial agent on the cell wall mainly inhibits the connection between the polysaccharide chain and the tetrapeptide crosslinking, so that the cell wall loses its integrity, loses the protection against osmotic pressure, damages the bacterial cells and causes death, and has a better antibacterial effect. The material of the wear-resistant layer is wear-resistant rubber, which has super wear resistance, impact resistance and tear resistance, and a long service life.

[0011] Preferably, the material of the first flame retardant layer is ammonium polyphosphate, and the material of the second flame retardant layer is also ammonium polyphosphate, which has a good flame retardant effect.

Moreover, the buffer layer 11 provided in the device can greatly enhance the bearing capacity of the device, enabling it to withstand greater pressure. Additionally, the oil-resistant layer 112 is made of chloroprene rubber, which can significantly improve the oil resistance of the heat-insulating inner tube 103, ensuring that the heat-insulating inner tube 103 will not be eroded by oil after long-term use, thus extending the service life of the hydraulic hose. For the structure of the flame-retardant and heat-insulating hydraulic hose, by setting the flame-retardant outer tube 101, the antioxidant coating 102 is a silver ion coating, which can interfere with the synthesis of cell walls, making the antibacterial effect of the device better. The wear-resistant layer 105 is made of wear-resistant rubber and has excellent wear resistance, impact resistance, and tear resistance, greatly enhancing the service life of the device. The first flame-retardant layer 106 is made of ammonium polyphosphate, and the second flame-retardant layer 109 is also made of ammonium polyphosphate, having a good flame-retardant effect.
