Description

Technical Field

[0001] This utility model relates to the field of metal hoses, specifically a high-temperature resistant and heat-insulating metal hose. Background Technology

[0002] High-temperature resistant insulated metal flexible hoses are specially designed pipe components that maintain stable performance and insulation effects in high-temperature environments. Made of special materials, they can withstand long-term operation under high temperatures without easily deforming or damaging, effectively reducing heat transfer and energy consumption. These hoses have a certain bending radius to adapt to various complex installation environments and space requirements. They are a special pipe component with high-temperature stability, excellent insulation performance, good flexibility, excellent sealing performance, and strong corrosion resistance. They have broad application prospects in industries such as petrochemicals, power, and metallurgy.

[0003] When using an existing high-temperature resistant heat-insulating metal flexible hose, the hose's long extension causes its outer surface to reach a high temperature. When operators use or pass by it, they are likely to come into contact with the outer surface of the hose, which can cause burns to the operators and also cause the hose to bend and be damaged.

[0004] Therefore, this utility model proposes a high-temperature resistant heat-insulating metal flexible hose to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant, heat-insulating metal flexible hose to solve the problems mentioned in the background art.

[0007] Bolts are installed at the connection between the upper and lower clamping plates. Cavities are opened in the inner walls of the upper and lower clamping plates. A water inlet pipe is installed at the top center of the upper clamping plate, and a water outlet pipe is installed at the bottom center of the lower clamping plate. A sealing plug is installed at the bottom of the water outlet pipe.

[0008] Preferably, a support rod is installed at the bottom of the lower clamping plate, and a mounting base is installed at the bottom of the support rod. Screws are installed on both sides of the upper clamping plate, and the bottom of the screws penetrates into the interior of the support rod.

[0009] Preferably, the upper and lower clamping plates have slots on their side walls, insert plates are installed inside the slots, and connecting plates are fixed to the side walls of the insert plates.

[0010] Preferably, both ends of the outer surfaces of the upper and lower clamping plates are provided with a plurality of slots, which are distributed in a circular array on the outer surfaces of the upper and lower clamping plates.

[0011] Preferably, a plug rod is installed through the inside of the slot, and a spring is installed on the outer surface of the plug rod. The bottom of the spring is fixed to the outer surfaces of the upper and lower clamping plates.

[0012] Preferably, a sealing cap is installed on the top of the water inlet pipe, and a thermometer is installed through the top of the sealing cap, with the bottom of the thermometer located inside the cavity.

[0013] Preferably, an exhaust valve is installed on the top of the sealing cover, and the exhaust valve is located on the side of the thermometer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The high-temperature resistant heat-insulating metal hose proposed in this utility model uses upper and lower clamps to protect the outer surface of the metal hose. At the same time, the cavities inside the upper and lower clamps facilitate the introduction of heat-insulating liquid or cold water for heat insulation treatment. This makes it convenient for operators to move the pipe and prevents operators from accidentally touching the outer wall of the hose body and getting burned due to the hot outer surface of the metal hose body.
