Embodiment Construction

[0012] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0013] like figure 1 , figure 2 As shown, a metal hose 1 connected to a large-diameter pump includes a pipe body 2, and the two ends of the pipe body 2 are respectively provided with a first connection end 31 and a second connection end 32, and the pipe body 2 is The double-layer structure consists of a rubber tube 41 and a wire braided tube 42 from the inside to the outside. Let the length of the metal hose be L, the radius of the rubber tube 41 be r, and the radius of the wire braided tube 42 be R, satisfying the following relationship : L=2r+3R, R=6r / 5, the rubber tube 41 and the wire braided tube 42 are fixedly connected by an elastic rubbe...

Abstract

The invention discloses a large-caliber pump coupling metal hose which comprises a hose body, wherein a first coupling end and a second coupling end are respectively arranged at the two ends of the hose body; the hose body is of a double-layered structure which comprises a rubber tube and a metal silk-woven tube from inside to outside; if the length of the metal hose is L, the radius of the rubber tube is r and the radius of the metal silk-woven tube is R, the relation is as follows: L=2r+3R and R=6r / 5; and the rubber tube and the metal silk-woven tube are fixedly connected through an elastic rubber layer. The large-caliber pump coupling metal hose disclosed by the invention comprises one inside rubber tube and one outside metal silk-woven tube, the rubber tube and the metal silk-woven tube are not separated, but fixedly connected through the elastic rubber layer, so that the rubber tube is not in contact friction with the metal silk-woven tube; meanwhile, the dimension design of the whole hose body is more scientific, so that the possibility of greatly bending the hose is reduced; and the rubber tube and the metal silk-woven tube are made of a material which is more resistant to ageing, so that the service life of the large-caliber pump coupling metal hose is greatly prolonged.

Description

technical field [0001] The invention relates to a metal hose, more precisely, a metal hose connected to a large-diameter pump. Background technique [0002] Metal hose is an important component in the connection pipeline of modern industrial equipment. Metal hoses are used as wire and cable protection tubes for wires, cables, automated instrument signals, and civil shower hoses, with specifications ranging from 3mm to 150mm. Small-diameter metal hoses (inner diameter 3mm-25mm) are mainly used for the protection of sensing lines of precision optical rulers and industrial sensor lines. Large-diameter metal hoses can be used for pump connections. However, the friction between the inner tube and the outer tube of the large-diameter pumps and metal hoses commonly used in the industry will aggravate the skin damage of the inner soft tube body, and the service life is generally shorter. Contents of the invention [0003] The invention mainly solves the technical problems existi...
