a connecting elbow

Abstract

The invention relates to the technical field of pipe connection elbows, in particular to a connection elbow, which includes an upper elbow and a lower elbow. A retaining ring is threaded on one side of the outer wall of the upper elbow and the lower elbow, and the outer wall of the retaining ring is A snap ring is sleeved, and a locking assembly is sleeved on the outside of the snap ring. The locking assembly includes a sleeve. A sealing ring groove is opened on the side of the inner wall of the sleeve close to the snap ring, and an equidistant annular structure is welded on the outer wall of the sleeve. Distributed torsion. Beneficial effects of the present invention can change the direction of the elbow, can dispose of the sundries filtered by the filter screen by separating the joints, prevent the elbow from being blocked due to the accumulation of filtered sundries, and ensure the one-way passage of the water flow inside the elbow It can prevent the reverse flow of the water flow, divert the water flow, effectively reduce the impact of the water flow on the elbow, thereby increasing the service life of the elbow, reducing noise, and preventing the elbow from freezing and cracking due to cold weather. Reduce the damage of external factors such as collisions to the elbow.

Description

technical field [0001] The invention relates to the field of pipeline connection elbows, in particular to a connection elbow. Background technique [0002] Elbow, a pipe fitting commonly used in pipeline installation, connects two pipes with the same or different nominal diameters to make the pipeline turn at a certain angle. It can be used for the connection at the corner of the pipeline to change the direction of the pipeline. Therefore, it has extremely broad application prospects. [0003] Chinese Patent No. CN208185718U provides a simple filter for water passing through the pipeline. At the same time, the two ends of the connecting elbow are provided with a limit device, and the connecting elbow is fixedly connected to the pipeline through the limit device, replacing the traditional threaded connection, increasing The service life of the connecting elbow, in order to achieve the above technical problems, the utility model discloses a pipe connecting elbow with a filter...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a connecting elbow to solve the inconvenient treatment of the filtered sundries proposed in the above-mentioned background technology, and the sundries will flow back into the pipeline with the water flow, the structure is relatively simple, the sealing effect is poor and the temperature is low. fragile problem
