Embodiment Construction

[0015] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0016] figure 1 and figure 2 The shown backflow detachable anti-wear elbow is composed of a shell 1, a top cover 2, a bolt 3 and a washer 4. The housing 1 is a right-angled pipe fitting with an inlet 1.3 and an outlet 1.1. The top cover 2 is an arc-shaped member bent along the wall of the housing 1. There is a gap on the outer curved wall of the housing 1 to seal and install the top cover 2. The two sides of the joint are respectively provided with a protruding cover edge 2.1 and The shell edge 1.2 and the paired edges are connected by bolts 3 and washers 4 to form a detachable structure. The casing 1 and the matching top cover 2 form an upwardly convex volute. The highest end of the volute is located on the upper wall of the neck of the outlet 1.1 and connected by an arc. The height difference between the two is equal to 0.5 to 1.2...

Abstract

The invention discloses a backflow-type detachable wear-resisting elbow comprising a housing, a top cover, a bolt and a gasket. The housing is a right-angle bent tube member, a notch is formed on the outer wall of the bent tube member for mounting the top cover in a sealing manner, and the housing and the top cover are connected to form a detachable structure through the bolt and the gasket. The housing and the top cover form an upward-convex-shaped spiral case, the top end of the spiral case is located on the upper wall of the neck of an outlet and are connected through an arc, and the tail end of the spiral case is connected with the outer wall of the neck of an inlet transitionally. The spiral-case-shaped inner wall allows a small part of inputted particle material to wriggle and backflow along the inner wall curve, the low-speed backflow particle material forms a barrier to protect the inner wall of the spiral case, and impact and wear on the inner wall of the spiral case by the inputted particle material are avoided. According to the structure, operating environment of the top cover can be improved greatly, so that the purpose of wear resistance is achieved; by the aid of the detachable structure, the top cover can be maintained or changed conveniently, so that maintenance cost is reduced.

Description

technical field [0001] The invention relates to a pipeline accessory, in particular, the invention relates to an elbow for changing the direction of a connecting pipeline, and the elbow is a backflow detachable anti-wear elbow. Background technique [0002] The use of pipelines to transport dry powder, slag, sand and gravel concrete and other granular materials in the project is an efficient transportation mode. It can send the materials to the designated location within the range of the output head of the pump, and the sequential transportation greatly reduces the intermediate transportation links and improves work efficiency. . The pipeline transports granular materials such as cement and sand, mainly relying on the airflow output by the pump to push the materials to obtain speed energy. The high-speed flow of granular materials will cause certain wear on the inner wall of the pipe. The elbow connecting the pipeline changes the direction of the pipeline, and the wear on t...
