Abstract
Description
Technical Field
[0001] The utility model relates to a reducing wear-resistant three-way connecting pipe, belonging to the technical field of connecting pipes. Background Art
[0002] Tailings are one of the invalid products in the ore dressing process, mainly including heavy metals such as mercury, cadmium, lead, chromium and toxic elements such as non-metallic sulfur and arsenic, as well as elements such as zinc, copper and nickel with certain toxicity. The leachate of tailings will cause pollution of groundwater and soil. Tailings are often treated by filter presses, and the filter presses need to be connected to conveying equipment for tailings treatment.
[0003] Pipes are one of the commonly used components in conveying equipment, generally used for conveying liquids or gases, such as water pipelines, oil pipelines and various liquid chemical material conveying pipelines, etc. Three-way pipes are commonly used components for changing the flow direction. Commonly used three-way pipes have casting, welding and hot extrusion forming methods. Three-way pipes are widely used in pipe networks for conveying liquids and gases. During the connection process of large pipelines, especially during the process of using filter presses to treat tailings, first, the flange needs to be welded and fixed to the pipeline and then the three-way pipeline is connected. And generally, the three-way needs to be welded to the pipeline, which has problems such as difficult replacement, serious wear and frequent maintenance. If not repaired and replaced in time after wear, it is easy to endanger personal health, damage the working environment, and the number of production stoppages for maintenance is large, increasing the labor intensity and reducing the work efficiency.

The inner diameter of the flange is adapted to the outer diameter of the pipe orifice it sleeves. A retaining ring is fixedly arranged at the outer end of the pipe orifice. Wear-resistant layers are arranged on the inner surfaces of the pipe body and the pipe orifices.
[0006] The effect of adopting the above technical solution is that flanges are sleeved on each pipe orifice of the three-way connecting pipe. The flanges can rotate on the pipe orifices and do not need to be welded, which is convenient for connecting with other pipelines. Only by connecting the flanges with the pipelines through screws, etc., it is not necessary to replace and maintain frequently. Wear-resistant layers are arranged on the inner surface of the three-way connecting pipe, extending the service life of the three-way connecting pipe. And a retaining ring is fixedly arranged at the outer end of the pipe orifice, which can ensure that the flange will not fall off, ensuring the convenience and safety of pipeline connection.
[0007] On the basis of the above technical solutions, the present utility model can also be improved as follows.
[0008] Further, the diameters of the first pipe orifice, the second pipe orifice, and the third pipe orifice are different.
[0009] The effect of adopting the above further solution is that the different diameters of the three pipe orifices are for matching the different sizes of various large pipes, and the pipe diameters can be set according to the sizes of the pipes that are often connected.
[0010] Further, an annular protrusion is provided on the inner ring of the flange, one end of the annular protrusion abuts against one end of the retaining ring, and a sealing ring is provided on the other end of the retaining ring.
[0011] The effect of adopting the above further solution is that the annular protrusion on the flange abuts against the retaining ring, which not only ensures the stability of the connection between the pipe and the flange, but also reduces the wear of the flange; a sealing ring is provided at one end of the retaining ring connected to the pipe, which can ensure the sealing performance of the pipe connection and prevent problems such as liquid leakage and gas leakage.
[0012] Further, the wear-resistant layer is a composite wear-resistant material.
[0013] The effect of adopting the above further solution is that the wear-resistant layer is selected as a composite wear-resistant material coating. In addition to achieving the wear-resistant effect, it is convenient for repair and prolongs the service life of the three-way pipe.
[0014] Further, an anti-corrosion pipe sleeve is fitted on the inner wall of the pipe body.
[0015] The effect of adopting the above further solution is that an anti-corrosion pipe sleeve is fitted on the inner wall of the pipe body to prevent the inside of the pipe body from being corroded and worn, and the anti-corrosion pipe sleeve is easy to replace.
[0016] Further, the first pipe orifice, the second pipe orifice, and the third pipe orifice are in a T shape or a Y shape.
[0017] The effect of adopting the above further solution is that the three-way connecting pipe can be made into a T shape or a Y shape according to the actual situation, which is convenient for use.
[0018] The technical solution provided by the present utility model has the following beneficial effects compared with the prior art:
[0019] The utility model can adapt to the connection of more pipes with different diameters by setting three pipe orifices with different diameters. A flange is sleeved on the pipe orifice, and a retaining ring is arranged at the end of the pipe orifice to ensure that the flange will not fall off during the process of connecting pipes, thus ensuring the convenience and easy operation of the connection. The inner surface of the tee connection pipe of the utility model is provided with a wear-resistant layer or lined with an anti-corrosion pipe sleeve, ensuring the wear resistance and anti-corrosion property inside, reducing the wear and corrosion inside the tee connection pipe, and further prolonging the service life of the tee connection pipe. The flange of the utility model is sleeved on the pipe orifice, and is provided with an annular protrusion and a retaining ring which are abutted against each other, further reducing the wear of the flange, reducing the frequency of replacement and maintenance, and saving labor and cost.
