Noise-reducing and anti-blocking bend

Abstract

The invention discloses a noise-reducing and anti-blocking bend which comprises a bent main body, wherein a threaded connector is mounted at one end of the bent main body; a filtering connector is inthreaded connection with the other end of the bent main body; a valve is arranged at one end of the bent main body and positioned below the threaded connector; the outer surface of the bent main bodyis covered with a sound-insulating layer; the outer surface of the sound-insulating layer is covered with a hard plastic tube; a sewage draining port is arranged at the bottom of the hard plastic tube, penetrates through the hard plastic tube, and communicates with the sound-insulating layer; a connecting plate is mounted on one side of the surface of the hard plastic tube; a telescopic rod is fixedly fixed on one side of the connecting plate through a hinge; and a fixing bracket is mounted at one end of the telescopic rod. The noise-reducing and anti-blocking bend has the noise-reducing and anti-blocking functions, and is convenient to fix, mount, repair and maintain; an obstruction to an inner cavity of the noise-reducing and anti-blocking bend can be conveniently removed without dismounting the noise-reducing and anti-blocking bend; and accordingly, the noise-reducing and anti-blocking bend has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of elbows, in particular to a noise-reducing and anti-blocking 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. Bending radius less than or equal to 1.5 times the pipe diameter belongs to the elbow, and greater than 1.5 times the pipe diameter belongs to the elbow. According to the angle, there are three most commonly used ones: 45°, 90°, and 180°. In addition, according to engineering needs, other abnormal angle elbows such as 60° are also included. In the existing existing pipeline systems, most blockage accidents are Occurred at the elbow, after the blockage occurs, it needs to be disassembled and cleaned, which is very troublesome, and the water flowing through the elbow will also produce some noise, and some elbows are not easy to fix, requiring...

According to the angle, there are three most commonly used ones: 45°, 90°, and 180°. In addition, according to engineering needs, other abnormal angle elbows such as 60° are also included. In the existing existing pipeline systems, most blockage accidents are Occurred at the elbow, after the blockage occurs, it needs to be disassembled and cleaned, which is very troublesome, and the water flowing through the elbow will also produce some noise, and some elbows are not easy to fix, requiring special fixing brackets, which is far from meeting the current people's expectations. The requirements of this product, so how to design a noise-reducing and anti-blocking elbow has become a problem we are currently trying to solve
