Expandable rubber hose

Abstract

This utility model provides an expandable rubber hose, relating to the technical field of expandable rubber hoses. The expandable rubber hose includes a rubber tube wall, with at least two layers of steel wire mesh radially spaced inside the tube wall. A rubber layer is filled between adjacent layers of steel wire mesh, passing through the wire mesh and connected to the rubber tube wall. Based on the technical solution of this utility model, because a rubber layer is filled between adjacent layers of steel wire mesh and passes through the wire mesh to connect to the rubber tube wall, during expansion, the rubber layer expands and deforms accordingly, always passing through the wire mesh and remaining connected to the rubber tube wall, thereby preventing delamination of the expandable rubber hose wall.

Description

Technical Field

[0001] This utility model relates to the field of expandable rubber hose technology, and in particular to an expandable rubber hose. Background Technology

[0002] An expandable rubber hose is a type of hose that can change its diameter, length, or volume under certain conditions. When the pressure of the liquid transported inside the expandable rubber hose is too high, the hose's diameter will increase and its length will decrease. To improve the expansion resistance of the expandable rubber hose, a wire mesh needs to be installed inside the hose wall. Existing expandable rubber hoses have two layers of stacked wire mesh inside the hose wall. When the pressure of the liquid transported inside the expandable rubber hose is too high and the hose's diameter increases, the diameter of the two stacked wire mesh layers also increases. Gaps can easily appear between the two layers of wire mesh, leading to delamination of the hose wall and affecting its subsequent use. Therefore, it is necessary to design an expandable rubber hose that can reduce the probability of gaps appearing between the two layers of wire mesh, causing delamination of the hose wall. Utility Model Content

[0003] To address the problems in the prior art, this application proposes an expandable rubber tube that can reduce the probability of gaps between two layers of wire mesh causing delamination of the tube wall.

[0004] This utility model provides an expandable rubber tube, which includes a rubber tube wall. At least two layers of steel wire mesh are radially spaced inside the rubber tube wall, and a rubber layer is filled between two adjacent layers of steel wire mesh. The rubber layer passes through the steel wire mesh and is connected to the rubber tube wall.

[0005] As a further improvement to the above technical solution:

[0006] Furthermore, in the aforementioned expandable rubber tube, the wire mesh comprises multiple strands of steel wires spaced circumferentially along the wall of the rubber tube. The steel wires are spirally arranged around the axial direction of the expandable rubber tube, and the spiral directions of the steel wires in adjacent layers of the wire mesh are opposite.

[0007] Furthermore, the aforementioned expandable rubber tube further includes at least ten steel wires.

[0008] Furthermore, in the aforementioned expandable rubber tube, the angle between the extending direction of the steel wire and the axial direction of the expandable rubber tube is 15°.

[0009] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of this utility model can be achieved.

[0010] The expandable rubber hose provided by this utility model has at least the following beneficial effects compared with the prior art: When in use, high-pressure liquid is injected into the expandable rubber hose. When the liquid pressure in the expandable rubber hose is too high, causing the diameter of the expandable rubber hose to increase, the diameter of the wire mesh also increases. Since a rubber layer is filled between two adjacent layers of wire mesh, and the rubber layer passes through the wire mesh and is connected to the rubber hose wall, the rubber layer will expand and deform accordingly during expansion, always passing through the wire mesh and connected to the rubber hose wall, thereby preventing the hose wall from delaminating. After use, the rubber layer and the rubber hose wall return to their original shape and shrink, thereby causing the wire mesh to recover.

[0028] This utility model embodiment provides an expandable rubber tube 100, which can reduce the probability of gaps easily appearing between the two layers of steel wire mesh 120, leading to delamination of the tube wall.

[0029] Please see Figure 1 and Figure 2 The expandable rubber tube 100 provided in this embodiment of the utility model includes a rubber tube wall 110. At least two layers of steel wire mesh 120 are radially spaced inside the rubber tube wall 110, and a rubber layer 130 is filled between two adjacent layers of steel wire mesh 120. The rubber layer 130 passes through the steel wire mesh 120 and is connected to the rubber tube wall 110.

[0030] In use, high-pressure liquid is injected into the expandable rubber hose 100 provided in this embodiment of the utility model. When the liquid pressure in the expandable rubber hose is too high, causing the diameter of the expandable rubber hose to increase, the diameter of the wire mesh 120 also increases. Since a rubber layer 130 is filled between two adjacent layers of wire mesh 120, and the rubber layer 130 passes through the wire mesh 120 and is connected to the rubber tube wall 110, the rubber layer 130 will expand and deform accordingly during expansion, always passing through the wire mesh 120 and connected to the rubber tube wall 110, thereby preventing the tube wall of the expandable rubber hose from delaminating. After use, the rubber layer 130 and the rubber tube wall 110 return to their original shape and shrink, thereby causing the wire mesh 120 to recover.

[0031] The expandable rubber tube 100 provided in this embodiment of the utility model, for details please refer to... Figure 3 and Figure 4 The wire mesh 120 includes multiple strands of steel wires 121 spaced circumferentially along the wall 110 of the rubber tube. The steel wires 121 are spirally arranged around the axial direction of the expandable rubber tube 100, with the spiral directions of the steel wires 121 in adjacent layers of wire mesh 120 being opposite. Each steel wire 121 includes at least ten steel wires 122. (Please refer to...) Figure 5Each steel wire 121 includes at least ten steel wires 122, thereby increasing the tensile strength of each steel wire 121, thereby improving the expansion resistance of the expandable rubber tube 100 provided in this utility model embodiment, and expanding the applicability of the expandable rubber tube 100 provided in this utility model embodiment.

[0032] In this embodiment, please refer to the following for details. Figure 2 The angle between the extending direction of the steel wire 121 and the axial direction of the expandable rubber tube 100 is 15°. When the pressure of the high-pressure liquid in the expandable rubber tube 100 provided in this embodiment of the invention reaches the maximum bearing pressure of the expandable rubber tube 100 provided in this embodiment of the invention, the steel wire 121 will be stretched to extend at a 45° angle to the axial direction of the expandable rubber tube 100 provided in this embodiment of the invention, thereby maximizing the anti-expansion force provided by the expandable rubber tube 100 provided in this embodiment of the invention.
