Plastic elbow

Abstract

The invention belongs to the technical field of pipes, and particularly relates to a plastic elbow. A first sliding groove is formed in the inner wall of the upper side of the elbow, a vibration plateis slidably connected in the first sliding groove through a spring, and the spring is fixedly connected with the inner wall of the first sliding groove; one side of the vibration plate and the waterinlet is provided with a spoiler, and the spoiler is hinged to the inner wall of the upper side of the elbow; the spoiler is connected with the side wall of the vibration plate through a steel wire rope; the inner wall of the lower side of the elbow is provided with a third sliding groove; a hinged plate is hinged in the third sliding groove; the upper surface of the hinged plate is in an arc design, and the upper surface of the hinged plate is attached to the inner wall of the elbow; rubber layers are fixedly connected to the side walls of the two sides of the third sliding groove, and the rubber layers are tightly attached to the side wall of the hinged plate; and an air cylinder is fixedly connected in the third sliding groove. The structure is simple, the inner wall of the plastic elbow can be cleaned, and environmental sanitation in the pipeline is improved; meanwhile, foreign matters such as hair can be effectively removed, and pipeline blockage is avoided; and use is convenient,and practicability is strong.

Description

technical field [0001] The invention belongs to the technical field of pipes, in particular to a plastic elbow. Background technique [0002] The elbow is a commonly used connection pipe fitting in pipeline installation. In the pipeline system, it is a pipe fitting that changes the direction of the pipeline. It is used to connect two pipes with the same or different nominal diameters to make the pipeline turn at a certain angle. The nominal pressure is 1-1.6Mpa. Due to the good comprehensive performance of the elbow, it is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding, etc. Divided by angle: there are 45° and 90°180° three most commonly used, in addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°; the blocking rod 9 starts to rotate, so it is divided ...

AI Technical Summary

Problems solved by technology

The present invention is mainly used to solve the problem that the inner wall of the plastic elbow in the prior art is difficult to clean, and there is dust and silt accumulation, which is easy to breed bacteria, attracts mice, cockroaches and other animals, emits foreign matter, and spreads germs; and foreign matter such as hair is very It is easy to accumulate in the existing plastic elbows, and cannot enter the sewer with the water flow, causing pipeline blockage and affecting the water flow rate of the sewage. In severe cases, it will cause sewer sewage to flow backward and affect normal life
