Embodiment Construction

[0011] Depend on figure 1 It is known that a crushable dredging rubber pipe includes a pipe body and a connecting rubber flange. The innermost layer of the pipe body is a high-strength, high-wear-resistant rubber layer, that is, the medium-resistant layer 1, and a high-strength skeleton reinforcement layer 2 is laid outside the medium-resistant layer 1. This reinforcement layer consists of several layers of high-strength cords, and the cords are pressed by Winding at a certain angle, and wrapping tightly on the metal part 4 in the rubber flange in the way of turning over the bag. Additional cord layers 3 are added outside the skeleton reinforcing layer 2 and at both ends of the pipe body. The cords are wound at a certain angle and at a certain length, and are tightly wrapped on the metal part 4 in the rubber flange in a turned-over manner. In order to improve the pressure resistance and tensile strength of the hose. Outside the cord layer is an outer rubber layer 5, which is...

Abstract

The invention relates to a dredging rubber pipe capable of being pressed flat. The dredging rubber pipe capable of being pressed flat comprises a pipe body and a connecting rubber flange. The pipe body is sequentially provided with a medium-resistant inner rubber layer, a skeleton enhancement layer, additional cord thread enhancement layers at the two ends of the pipe body, an outer rubber layer and a colored rubber belt with the partial outer surface being thickened from interior to exterior. The dredging rubber pipe capable of being pressed flat is characterized in that the skeleton enhancement layer and the multiple cord thread layers additionally added on the exterior of the skeleton enhancement layer and the two ends of the pipe body are tightly attached to metal pieces in rubber flanges in a wrapping manner. The dredging tuber pipe capable of being pressed flat adopts a rubber flange manner, high-strength fabric is selected as the skeleton enhancement layer, the bearing pressureand moderate flexibility and flattening of the rubber pipe are guaranteed, and the strength and the flexibility reach the optimal effect; and high-strength cord threads are additionally laid at the two ends of the pipe body so as to guarantee the stability of the product performance.

Description

technical field [0001] The invention relates to a crushable dredging rubber hose. Background technique [0002] The pipelines used to transport mud in areas such as land pipelines in dredging projects are generally connected with three-way fittings to transport the mud to different directions. After the pipe joint is removed, the metal blind plate is added to seal it. Such an operation not only needs to stop the dredging operation first, but also is troublesome. Contents of the invention [0003] In view of the above actual situation of dredging operation, the purpose of this invention is to provide a kind of crushable rubber tube, which is connected to different ends of the tee fittings of the land pipeline. The tube is compressed in the direction of the cross section, so that it is completely compressed and closed to intercept the mud. This can be done without stopping the dredging operation, increasing operational efficiency. [0004] The technical solution of the p...
