A tensile hose for oil tank drainage system

Abstract

The invention discloses a tensile hose for an oil tank drainage system. The tensile hose comprises a hose body, the two ends of the hose body are provided with terminals, the hose body is connected toa floating roof through the terminal at one end in a fastened manner, the other end is connected to an oil tank in a fastened manner, the upper portion of the floating roof communicate with the exterior of the oil tank, the hose body is provided with annular connecting blocks distributed in an array, the annular connecting blocks are provided with annular connecting members, the annular connecting members are provided with symmetrically-distributed first connecting slots, rotating members arranged in an array are arranged between the two terminals, the rotating members are rotationally provided with triangular connecting rings arranged in an array, the triangular connecting rings are provided with rings in a sleeved manner, and every two adjacent rotating members are connected through thecorresponding triangular connecting ring and the corresponding ring. The tensile hose is limited by the rotating members, the triangular connecting rings and the rings, the floating roof is located at the top of the oil tank, the hose bears own gravity and oil pressure, the load of the hose is large, the strength of the hose is increased, and the tensile deformation of the hose in the axial direction is reduced.

Description

technical field [0001] The invention relates to a hose, in particular to a tensile hose used in an oil tank drainage system. Background technique [0002] There is a drainage system on the floating roof of the oil tank to drain the water falling into the floating roof during the rainy season. The main component of the drainage system is a hose. One end of the hose is connected to the floating roof, and the other end is connected to the outside of the oil tank. Natural drainage of rainwater on the floating roof. The hose structure in the prior art is single, most of the oil tanks store oil, and the floating roof is located above the oil tank, at this time, the hose bears the double load of its own gravity and oil pressure, and the hose is easily stretched Deformation, resulting in rupture of the hose and oil leakage. Contents of the invention [0003] The object of the present invention is to provide a tensile hose used in the oil tank drainage system. The main body of th...
