A hose with a metal fitting includes a hose; a metal fitting including a metal-fitting cylindrical portion to which one end portion of the hose is connected; and a sleeve covering the hose and the metal-fitting cylindrical portion. The inside of the hose communicates with the inside of the metal fitting. The hose includes an inner-surface resin layer, a metal-wire reinforced layer, and an outer-surface resin layer which are lined up in order from the inner side of the hose. The inner-surface resin layer is formed of a single layer containing fluororesin. The sleeve includes a first cylindrical portion covering the metal-fitting cylindrical portion; and a second cylindrical portion which directly covers the hose and which is smaller in diameter than the first cylindrical portion. The length of the second cylindrical portion is 8 mm or more. The thickness of the second cylindrical portion is 1 mm or more. The hardness of the second cylindrical portion is measured in compliance with JISK6253 by Durometer Type A and is 70 or more and 95 or less. A material of the sleeve is thermoplastic elastomer or rubber. The material of the sleeve is the same as a material of the outer-surface resin layer.

A high-pressure hose includes an inner tube, a first braided layer and a second braided layer. The inner tube defines an axial direction and a circumferential direction. The first braided layer includes a plurality of first braiding yarns and a plurality of first imaginary axes. Each of said first imaginary axes is passed through a plurality of first intersections of the plurality of first braiding yarns. The second braided layer is sleeved around the first braided layer and includes a plurality of second braiding yarns and a plurality of second imaginary axes. Each of said second imaginary axes is passed through a plurality of second intersections of the plurality of second braiding yarns. The plurality of first imaginary axes are at least partially misaligned with the plurality of second imaginary axes in a radial direction of the inner tube.

The present invention provides a steel wire pre-embedded integrated full-bore acid fracturing hose assembly, including a hose that sequentially includes an inner liner, an internal adhesive layer, a steel wire layer, and an external adhesive layer from inside out; and, a joint that includes a protective sleeve disposed between the external adhesive layer and the steel wire layer, a locking sleeve sleeved on an outer side of the internal adhesive layer, and an outer sleeve disposed outside the inner liner, which are sequentially disposed from inside out along an axial direction of the hose; an outer circumferential surface of the locking sleeve is provided with a tooth groove, and a steel wire of the steel wire layer is embedded in the tooth groove and locked; and the outer sleeve is in a threaded connection with the locking sleeve and the protective sleeve.

A pinch valve 1 comprises a tube body 3 made of an elastic material having a flow path formed inside, a pressing part 4, a rod member 6 attached to a front end of the pressing part 4, and a coupling part 35 provided on the outer surface of the tube body 3 and coupling the rod member 6 to the tube body 3 in a transverse arrangement with respect to the tube body 3, wherein pressing or releasing the tube body 3 by the pressing part 4 through the rod member 6 makes the tube body 3 deform and opens or closes the flow path.

A hose with a metal fitting includes a hose, a metal fitting connected to an end portion of the hose, and a sleeve covering at least a portion of the hose and metal fitting. The inside of the hose communicates with the inside of the metal fitting. The hose includes an inner-surface resin layer, a metal-wire reinforced layer, and an outer-surface resin layer. The sleeve includes a first cylindrical portion covering a portion of the metal fitting and a second cylindrical portion directly covering a portion of the hose. The length of the second cylindrical portion is 8 mm or more. The thickness of the second cylindrical portion is 1 mm or more. The hardness of the second cylindrical portion is measured in compliance with JISK6253 by Durometer Type A and is between 70 and 95. The material of the sleeve and the outer-surface resin layer are the same.

The present disclosure relates to a composite garden hose, comprising a hose body, a first connector and a second connector. The hose body sequentially comprises, from the inside out, a first tubular component made of an elastic material, a second tubular component with a corrugated structure and a third tubular component made of a fabric material, collectively achieving water conveyance, expansion limitation and protective functions.
