FIG. 2 is a block diagram of the wear ring of the present invention;
fig. 3 is an internal structural view of the wear ring of the present invention.
The sequence numbers in the figures illustrate: the rubber tube comprises a rubber tube body 1, a wear-resistant ring 2, a wear-resistant ring upper part 3, a wear-resistant ring lower part 4, an indication cavity 5, a fixing part 6, an arc-shaped surface 7, an opening 8 and a reinforcing layer 9.
Detailed Description
The rubber tube with the wear-resistant rings comprises a rubber tube body 1, a plurality of coaxial wear-resistant rings 2 are arranged in the rubber tube body along the length direction of the rubber tube body, and the inner diameters of the wear-resistant rings and the rubber tube are basically the same. The wear-resistant ring can effectively slow down the abrasion process of the rubber pipe, is usually processed by cutting, curling and welding steel plates and is integrally connected with the rubber pipe. The section of the wear-resistant ring is dumbbell-shaped; the upper part 3 of the dumbbell-shaped wear-resisting ring is matched with a reinforcing layer 9 in the rubber tube body. In particular, they may be welded or adhesively bonded, or lapped together, and may also increase their strength.
An indicating cavity 5 is arranged in the dumbbell-shaped wear-resistant ring, an indicator is arranged in the indicating cavity, the indicator is a displayable agent and comprises a pigment, a color paste, a solvent capable of changing the color, the PH value and other properties of fluid conveyed inside, and the like, so that an observer can judge that the indicator seeps out by observing the property change of the fluid outside, and the internal wear condition is obtained. The number of the indicating cavities is two, and different indicators are arranged in the first indicating cavity at the lower part and the second indicating cavity at the upper part. For example, if the lower part (paraxial position) is yellow dye and the upper part is red dye, the wear should be considered as early wear when yellow appears, and should be replaced immediately when red appears and is severely worn.
The upper part of the dumbbell-shaped wear-resistant ring is provided with a plurality of fixing parts 6 which are integrally connected with the side surface of the upper part of the wear-resistant ring and point to the lower part of the wear-resistant ring, namely the axial direction of the hose. The fixed part enables the wear-resistant ring to be better combined with the pipe body, and movement is prevented.
The outer surface of the dumbbell-shaped wear-resisting ring lower part 4 is an arc-shaped surface 7, and the joint between the vertical surface and the horizontal surface of the lower part is arc-shaped when viewed from a sectional view.
The enhancement layer is a steel wire braided layer or an armor layer.
The lower part of the wear-resistant ring is obliquely provided with an opening 8 which is a semi-closed hole, the two corresponding openings are arranged in an inverted splayed shape, and the lower part of each opening is opened on the lower surface of the wear-resistant ring.
In the structure of the utility model, the wear-resistant ring is set to be dumbbell-shaped, which can increase the bonding strength with the rubber tube body, the upper part and the lower part of the wear-resistant ring are convex relative to the waist, thus avoiding the defect that the existing rectangular sections are easy to be separated due to the upper and lower parts being in the same order, and the radial displacement is not easy to occur; meanwhile, the ratio of the working surface to the whole volume is increased, and under the condition of the same working surface, the volume of the whole ring body is reduced, namely the weight is reduced. The working surface of the wear-resistant ring is a surface of which the lower part is in contact with fluid, so that the weight of the whole ring body is reduced under the condition that the area of the working surface is unchanged, the weight of the pipe is also reduced, and the wear-resistant ring is easier to float and the like. And the weight is reduced, and more rings can be arranged in turn, so that the wear-resisting effect can be further improved. Further, since the waist portion has a small area, the influence of bendability and flexibility of the entire tube is small. The arc-shaped surface below the wear-resistant ring is arranged, so that internal fluid has a tendency of running towards the center when passing through, and the abrasion to the inner wall is reduced; the arrangement of the opening ensures that the lower part of the wear-resisting ring is guided and maintains the angle of the lower part as much as possible under the condition of wearing to a certain degree, thereby reducing the wearing speed. The utility model discloses in, still be provided with and instruct the chamber, when wearing and tearing to a certain extent, instruct the chamber open and with the fluid contact, its inside indicator and fluid mix, make the fluid property change, like available red pigment or dyestuff, make the fluid have red to make operating personnel can judge the inside wearing and tearing condition of tubular product through observing fluidic colour at the opening part of pipeline, avoided unpredictable loss. The wear-resistant ring can be formed by welding two circular rings, namely, the wear-resistant ring is formed by cutting two halves along the middle of a ring body in a drawing and then welding, a recess of an indicating cavity is prepared before welding, a cavity is formed after welding, a conveying hole is drilled, and an indicator is injected and then sealed. The preparation can also be carried out by other existing methods such as casting and the like.
