Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of corrugated pipes, and particularly relates to a corrugated pipe connecting device convenient to install and dismount. BACKGROUND

[0002] A metal corrugated pipe is a pipe material with a regular wave shape. Commonly used metal corrugated pipes are made of carbon steel and stainless steel, and there are also steel-lined plastic and aluminum pipes. The metal corrugated pipe is mainly used for connecting pipes and connecting pipes and equipment in situations where a small bending radius is required, non-concentric axial transmission, irregular turning, expansion and contraction, absorption of thermal deformation of the pipe, and installation of fixed elbows.

[0003] The patent with the publication number CN113606378A discloses a novel corrugated pipe connecting device, which comprises a corrugated pipe, a first tray assembly and a second tray assembly. One end of the corrugated pipe is sealed with the first tray assembly, and the other end is sealed with the second tray assembly. The corrugated pipe is sleeved on the outer side of a valve rod. The valve rod passes through a valve cover assembly and is inserted into a valve body. The valve cover assembly and the valve body are connected by a connecting body. The first tray assembly is sealingly arranged between the valve cover assembly and the connecting body. The second tray assembly is sealingly arranged on the side wall of the valve rod in the valve body. The corrugated pipe is sealingly arranged on the outside of the valve rod by the first tray assembly and the second tray assembly, so that the valve rod can be contained in a vacuum state, avoiding direct contact with the medium and enhancing the service life of the valve rod.
