Problems solved by technology

[0002] Hydraulic hoses are also called hydraulic oil hoses, hydraulic hoses, high-pressure hoses, etc. The materials mainly include rubber materials and rubber-plastic materials. They are often used for the transmission of modern petroleum-based liquids, water-based liquids, etc. The existing hydraulic hoses bear pressure. Low, weak aging resistance, poor softness, affecting daily use and service life, not conducive to large-scale promotion and use

Embodiment Construction

[0009] Embodiments provided by the present invention are described in further detail in conjunction with the accompanying drawings:

[0010] Such as figure 1 As shown, a rubber hose with a reinforced layer includes an inner rubber layer 1, a reinforced layer 4, a middle rubber layer 2 and an outer rubber layer 3, the inner rubber layer 1 is a hollow pipe body, and the inner rubber layer 1 The inner diameter ranges from 43 to 52 mm, the wall thickness ranges from 0.8 to 1.8 mm, and the thickness unevenness is less than 0.3 mm. The middle rubber layer 2 has two layers, and the wall thickness ranges from 2 to 15 mm. The reinforcing layer 4 is closely connected The outer surface of the inner rubber protection layer has a wall thickness of 2-20mm, and the working pressure is greater than 1MPa. The outer rubber layer 3 is closely connected to the outer surface of the middle rubber layer, and the wall thickness ranges from 1.5-2.5mm.

[0011] The rubber hose of the present invention...

Abstract

The invention discloses a rubber pipe with an enhancement layer. The rubber pipe comprises an inner rubber layer, the enhancement layer, two middle rubber layers and an outer rubber layer. The inner rubber layer is a hollow pipe body. The internal diameter of the inner rubber layer ranges from 43 mm to 52 mm, the thickness of the wall of the inner rubber layer ranges from 0.8 mm to 1.8 mm, and the unevenness of the thickness of the inner rubber layer is smaller than 0.3 mm. The thickness of the wall of each middle rubber layer ranges from 2 mm to 15 mm. The outer rubber layer is tightly connected with the outer surfaces of the middle rubber layers, and the thickness of the wall of the outer rubber layer ranges from 1.5 mm to 2.5 mm. The rubber pipe has the advantages of being stable in chemical performance and structure and resistant to oil, high temperature, aging and weathering.

Description

technical field [0001] The invention relates to a rubber hose with a reinforcing layer. Background technique [0002] Hydraulic hoses are also called hydraulic oil hoses, hydraulic hoses, high-pressure hoses, etc. The materials mainly include rubber materials and rubber-plastic materials. They are often used for the transmission of modern petroleum-based liquids, water-based liquids, etc. The existing hydraulic hoses bear pressure Low, weak aging resistance, poor softness, which affects daily use and service life, and is not conducive to large-scale promotion and use. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a rubber hose with a reinforcing layer. [0004] The technical solution of the present invention is: a rubber hose with a reinforced layer, including an inner rubber layer, a reinforced layer, a middle rubber layer and an outer rubber layer, the inner rubber layer is a hollow pipe body, and the inner di...
