Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal hoses, and particularly relates to a corrosion-resistant metal hose. Background Technique
[0002] A corrosion-resistant metal hose is a hose specially designed for use in corrosive environments. It is made of metal materials with excellent corrosion resistance and is usually used to transport corrosive liquids or gases, or to provide flexible connections in harsh environments such as high humidity and salt spray. The following are several common corrosion-resistant metal hose materials: stainless steel, Hastelloy, Monel alloy, titanium alloy, and tantalum. Corrosion-resistant metal hoses are widely used in the fields of chemical industry, petroleum, pharmaceuticals, ocean engineering, etc. to ensure safe and reliable operation in harsh environments.
[0003] When a metal hose is connected to other equipment, matching joints are required. However, most of the existing joints are integrated with the metal hose and cannot be effectively disassembled and replaced. When the joint is damaged or leaks, the joint cannot be replaced separately, which may lead to the need to replace the entire hose assembly, increasing the maintenance cost and time. The joint is the most vulnerable part of the hose system to leakage and fatigue damage. If the damaged joint cannot be replaced in time, it may lead to system failures or accidents. Moreover, when it is necessary to change the pipeline connection or adjust the equipment position, the non-replaceable joint may not be able to adapt to the new installation requirements, resulting in the need to reinstall or modify the pipeline system. Content of the Utility Model
[0004] The purpose of the utility model is to provide a corrosion-resistant metal hose to solve the problems raised in the above background technique.

[0006] A metal pipe layer arranged inside the hose body, a corrugated layer is fixed on the outside of the metal pipe layer, a blackening layer is arranged inside the metal pipe layer, a ceramic layer is arranged inside the blackening layer, a silica gel layer is arranged inside the ceramic layer, an electroplated layer is arranged inside the silica gel layer, and installation mechanisms for connection are arranged at both ends of the hose body.
[0007] Preferably, the material of the metal pipe layer is set as brass with corrosion-resistant effect, and the material of the corrugated layer is set as a stainless steel wire mesh with high flexibility.
[0008] Preferably, the blackening layer is made by an oxidation treatment method, and the ceramic layer is made by spraying ceramic materials.
[0009] Preferably, the material of the silica gel layer is set as chemical-resistant silica gel, and the material of the electroplated layer is set as tin plating with corrosion resistance and non-toxicity.
[0010] Preferably, the installation mechanism includes a pin fixed to the inner side of the electroplated layer, and a positioning ring is fixed to the outer side of the pin.
[0011] Preferably, a locking nut is rotatably connected to the outer side of the positioning ring, the locking nut is sleeved on the outer side of the corrugated layer, and a rubber gasket is provided on the inner wall of the locking nut.
[0012] Preferably, a union is threadedly connected to the inner wall of the locking nut, the union is rotatably connected to the outer side of the positioning ring, an adjustment disc is fixed to the outer side of the union, and a mounting nut is provided on one side of the union.
[0013] Preferably, a rotating groove is formed in the inner wall of the union, a rotating ring is rotatably connected to the inner wall of the rotating groove, and the rotating ring is fixed to one side of the mounting nut.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] By setting the installation mechanism, the present utility model can replace the joint of the metal hose in real time. When the joint is damaged or leaks, the joint can be replaced separately without replacing the entire hose assembly, reducing the maintenance cost and time. Since the joint is the most vulnerable part of the hose system to leakage and fatigue damage, if the damaged joint can be replaced in time, system failures or accidents can be avoided. At the same time, when it is necessary to change the pipeline connection or adjust the equipment position, replacing the joint in time can meet the new installation requirements.

The blackened layer 13 cooperates with the ceramic layer 14 to improve the strength and wear resistance inside the metal pipe layer 11, so as to avoid the situation that the metal hose is damaged by moisture when exposed to the air for a long time, thereby improving the service life of the metal hose; the material of the silicone layer 15 is set as chemically resistant silicone, and the silicone layer 15 can improve the elasticity or chemical resistance of the pipeline; the material of the electroplated layer 16 is set as tin plating with corrosion resistance and non-toxicity, and the electroplated layer 16 can improve the corrosion resistance of the metal hose and extend the service life.
[0024] Please refer to Figure 2 and Figure 4As shown in the figure, the installation mechanism 2 includes a clamping pin 21 fixed to the inner side of the electroplating layer 16. By setting the clamping pin 21, it can be fixed to the inner side of the hose body 1. A positioning ring 22 is fixed to the outer side of the clamping pin 21. By setting the fixing ring, the locking nut 23 can be limited to prevent it from falling off the outer side of the hose body 1 of the corrugated layer 12. The locking nut 23 is rotatably connected to the outer side of the positioning ring 22. The inner wall of the locking nut 23 is provided with a rubber gasket 24. By setting the rubber gasket 24, the sealing performance during connection can be improved. The inner wall of the locking nut 23 is threadedly connected to a union 25. The union 25 is rotatably connected to the outer side of the positioning ring 22. By setting the union 25, it is convenient to threadedly connect with the locking nut 23 and is also convenient for disassembly and replacement. A regulating disc 26 is fixed to the outer side of the union 25. By setting the regulating disc 26, it is convenient to rotate the union 25. An installation nut 27 is provided on one side of the union 25. By setting the installation nut 27, it can be connected to other devices. A rotating groove 28 is formed in the inner wall of the union 25. A rotating ring 29 is rotatably connected to the inner wall of the rotating groove 28.

[0025] Working principle: The metal hose is composed of a hose body 1 and installation mechanisms 2 at both ends. The hose body 1 is composed of a metal pipe layer 11, a corrugated layer 12, a blackening layer 13, a ceramic layer 14, a silicone layer 15, and an electroplating layer 16. The material of the metal pipe layer 11 is set as brass with corrosion resistance. Brass has good corrosion resistance, and in some cases (such as the rainwater drainage system), the antibacterial property of brass is also an advantage. The material of the corrugated layer 12 is set as a stainless steel wire mesh with high flexibility. The design of the corrugated layer 12 can withstand the working pressure of the hose, adapt to environmental conditions, and have sufficient flexibility to allow expansion and contraction. The blackening layer 13 is made by an oxidation treatment method, and the ceramic layer 14 is made by spraying ceramic materials. The blackening layer 13 cooperates with the ceramic layer 14 to improve the strength and wear resistance inside the metal pipe layer 11, which can avoid the situation that the metal hose is damaged by moisture when exposed to the air for a long time, thereby improving the service life of the metal hose. The material of the silicone layer 15 is set as chemically resistant silicone. The silicone layer 15 can improve the elasticity or chemical resistance of the pipeline. The material of the electroplating layer 16 is set as tin plating with corrosion resistance and non-toxicity. The electroplating layer 16 can improve the corrosion resistance of the metal hose and extend its service life. When the hose body 1 is in use, it can be threadedly connected to other devices through the installation nut 27 and the union 25. When it is necessary to replace the models of the installation nut 27 and the union 25, the union 25 can be removed by rotating the regulating disc 26 and the locking nut 23 in the opposite direction at the same time. The locking nut 23 is equipped with a rubber gasket 24 to prevent leakage.
