Abstract
The utility model relates to a composite type soft tube, which is composed of an inner tube and a spiral spring in the inner tube, and the outer wall of the inner tube is covered with one layer or a plurality of layers of metal screen sleeves and soft sleeves. The utility model has the advantages of high strength, good elasticity, hard deformation and break and small flow resistance, and the utility model is suitable for transferring various corrosive media.
Description
The utility model relates to a kind of compound flexible pipe.
Existingly mainly contain rubber combined pipe and metal composite pipe in order to the compound flexible pipe that transmits Korrosionsmediums such as acid, alkali, oil, gas or powdery flowable materials.The major defect of rubber combined flexible pipe is distortion easy to crack, and intensity is low, and is not high pressure resistant.Though metal composite pipe intensity height, resistance to pressure is better, poor flexibility, and yielding fracture behind the bending motion, and inner tube wall is corrugated, and rough, big to the flowing medium resistance.
The purpose of this utility model provides a kind of intensity height, good springiness, not yielding fracture, inner wall smooth, the high-strength high pressure hose that flow resistance is little.
The utility model is made up of the helical spring (2) in interior pipe (1) and the interior pipe (1), and interior pipe (1) outer wall has cladded layer of metal net (3) at least.Metal net (3) is outer can set up a soft lining (4).The end of body at least can an affixed joint (5).Interior pipe (1) can be the PVC plastic flexible pipe.
Because the utility model is multi-layer compound structure, have the advantage of metallic hose and rubber hose simultaneously, the intensity height, good springiness, corrosion-resistant, high pressure resistant, bending motion arbitrarily.Inner wall smooth, the medium flow resistance is little, long service life.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is a twin adapter embodiment External view
Among the figure: 1 is interior pipe, and 2 is helical spring, 3,3 ', 3 " be the metal net, 4,4 ', 4 " be soft lining.
Interior pipe (1) is the PVC plastic flexible pipe, and helical spring (2) is installed in the interior pipe (1) with Shooting Technique, and metal net (3) is the metal wire knitted net, is fastened on interior pipe (1) outer wall, can be one or more layers.Gentle matter such as the available cloth of soft lining (4), rubber, plastics have certain flexible material, and soft lining (4) is fastened on the outer wall of metal net (3).Metal net and soft lining can be provided with one or more layers as required at interval.Joint (5) (5 ') is fixed on hose end, also can one or two be set as required.
Claims (4)
1, high-strength high pressure hose is made up of the helical spring (2) in interior pipe (1) and the interior pipe (1), it is characterized by interior pipe (1) outer wall and has cladded layer of metal net (3) at least.
2,, it is characterized by the outer soft lining (4) that is provided with of metal net (3) by the described a kind of high-strength high pressure hose of claim 1.
3, by the described a kind of high-strength high pressure hose of claim 1, the end that it is characterized by body is connected with a joint (5) at least.
4, by the described a kind of high-strength high pressure hose of claim 1, it is characterized by interior pipe (1) is the PVC plastic flexible pipe.
