Description
Technical Field
The utility model belongs to the technical field of the pipe fitting, a loose joint takeover assembly is related to.
Background
In water supply and drainage works, water needs to be conveyed through pipelines which are formed by connecting various pipes. The tube may be classified into a hard tube and a soft tube according to the texture of the material. Joints are often provided between pipes, and for ease of installation, it is widely used to secure loose joints to pipes. The loose joint connector is arranged on the connecting pipe to form a loose joint connecting pipe assembly.
The Chinese patent literature data discloses a loose joint elbow [ application number: CN 201520793998.5; the notice number is: CN 205065153U ], which comprises a nut, which is sleeved on one end of the elbow body. The nut is provided with an annular inner groove, the elbow body is provided with an annular bulge matched with the inner groove, and the elbow body is sleeved with a sealing gasket. The nut, the elbow body and the sealing washer form a loose joint.
The other end of the elbow body is fixedly connected with the connecting pipe, when the butt joint pipe is connected through the nut, the butt joint pipe is inserted into the nut, the nut is rotated to enable the nut to be in threaded connection with the butt joint pipe, and the nut is screwed up to enable the butt joint pipe to abut against the sealing gasket to form sealing.
