Problems solved by technology
[0002] At present, the commonly used pipelines for the transmission of solid-liquid mixtures at home and abroad have steel pipes lined with ceramics. Although this pipeline can meet the transmission of solid-liquid mixtures, the production and construction costs of the pipeline are relatively high, and ceramics often fall off at the transition points, and the inside of the steel pipe The phenomenon of layer corrosion and wear is very serious, and even perforation occurs, which greatly reduces the service life of the pipe. The wear-resistant PE material has been studied in depth, and there are many wear-resistant PE products on the market. It is expected to use this wear-resistant PE pipe instead The steel pipe

Embodiment 1
[0024] The structure of the plastic elbow described in this embodiment is as follows: figure 1 As shown, the elbow is a 45° elbow. The elbow is composed of an inner layer 1 and an outer layer 2 covering the surface of the inner layer; a convex portion 3 is provided on the side where the inner layer is in contact with the outer layer. figure 2 It can also be seen that two grooves 4 and 5 are provided on the side where the inner layer is in contact with the outer layer, and the top of the protrusion 3 is hook-shaped so that the inner layer and the outer layer are tightly connected through the hook-shaped structure. The convex part can ensure that the inner layer and the outer layer are closely connected, and can prevent the inner and outer layers from falling off during the transportation of the mixed solid-liquid object. The grooves 4 and 5 are symmetrically distributed on both sides of the protrusion 3 . The side of the inner layer that is not in contact with the outer laye...

The invention discloses a plastic elbow which is composed of an inner layer and an outer layer covering the surface of the inner layer. One side, in contact with the outer layer, of the inner layer is provided with a plurality of protruding parts and a plurality of grooves. The top ends of the protruding parts are in a hook shape so that the inner layer and the outer layer can be closely connected through the hook structure. By means of the design of the inner layer structure, the inner layer and the outer layer can be closely connected, and the inner layer cannot disengage in the process of conveying mixed solid and liquid objects. The inner layer of the elbow is made of abrasion resisting materials, the abrasion resistance of the elbow is improved, and the plastic elbow is combined with an abrasion resisting PE pipe to replace a ceramic steel tube to convey solid and liquid mixtures.
Description
technical field [0001] The invention relates to the field of pipe connection parts, more specifically, to a plastic elbow. Background technique [0002] At present, the commonly used pipelines for the transmission of solid-liquid mixtures at home and abroad have steel pipes lined with ceramics. Although this pipeline can meet the transmission of solid-liquid mixtures, the production cost and construction cost of the pipeline are relatively high, and ceramics often fall off at the transition points, and the inside of the steel pipe The phenomenon of layer corrosion and wear is very serious, and even perforation occurs, which greatly reduces the life of the pipe. The wear-resistant PE material has been studied in depth, and there are many wear-resistant PE products on the market. It is expected to use this wear-resistant PE pipe instead. The steel pipe. The replacement of steel pipes by PE pipes also needs to solve the pressure problem at the joints of pipes. Contents of th...
