A Split Flange Connection Rotary Joint

Abstract

A flange sectioning connection type rotary connector consists of a shell, a moving ring, an end cover, a spring, a spring pad, a bearing bush, a sealing material and a semicircular sealing ring which are assembled together and is characterized in that the shell and the moving ring are both of an opposite-open sectioning structure, a positioning block is positioned by a positioning slot thereof, and a sectioning surface is fixedly connected into a whole by a bolt group. The end cover is fixed at the shaft end of the sectioning shell, the sectioning shell and the bearing bush are connected by a positioning annular slot and a positioning bugle, the shell and a rotary shaft fixing member are connected, and a static part is formed; the moving ring and a rotary shaft are fixedly connected to form a rotary part; the end cover, the spring and the spring pad form a pressing mechanism; the pressing mechanism tightly presses the moving ring on the semicircular sealing ring, such that the rotary connector is sealed for the first time, a rotary shaft hole of the moving ring, the rotary shaft and a rotary shaft hole of the shell are connected to form annular vacuum, a sealing material is filled, and the rotary connector is sealed for the second time. The flange sectioning connection type rotary connector is simple in structure, accurate in radial positioning, firm in sealing and simple and fast to detach, replace and mount.

Description

technical field [0001] The invention relates to a connection part, in particular to a split flange connection type rotary joint. Background technique [0002] Rotary joint is a connection and sealing device for inputting fluid medium from static pipeline to rotating equipment, widely used in printing and dyeing, chemical fiber, non-woven fabric, synthetic leather, plastic, rubber, paper, petroleum, chemical, steel and other industries. The currently recognized radial positioning of rotary joints is mainly done based on experience. Inaccurate positioning can easily cause joint deflection and jumping; the auxiliary seal O-ring at the shaft end is aging and fails, which is likely to cause leakage; the working environment is harsh, the wear is serious, and the maintenance cycle Shorter; the structure of the rotary joint is complex, and the installation, disassembly and replacement of parts are cumbersome and difficult; the service life is short, and it is extremely difficult to ...
