NOVELTY - The utility model claims a cold-resistant and low-temperature resistant metal hose, the technical solution comprises: a control box and a silica gel sleeve, the inner surface of the silica gel sleeve is provided with a heat preservation layer, the inner surface of the heat preservation layer is provided with a rock cotton layer, the inner surface of the rock cotton layer is provided with a rubber layer, the middle part of the inner part of the heat preservation layer is provided with a graphene heating cloth, one side of the top part of the silica gel sleeve is provided with an assembling groove, the inner surface of the assembling groove is clamped with a control box, the middle of one side of the control box is provided with a temperature sensor, one side of the bottom of the control box is provided with a controller, the bottom of the control box close to one side of the controller is installed with a battery. A cold-resistant and low-temperature resistant metal hose solves the problem that most of the existing metal hose cold-resistant and low-temperature-resistant effect is limited, at low temperature weather, it is easy to frost crack, and the medium is easy to be influenced by low temperature, affecting the normal transmission of the medium, it improves the cold-resistant and low-temperature resistant performance of the hose, so as to ensure the normal transmission of the conveying medium .
