The annular stop block is equally divided into a plurality of sections, and the section shape of the annular stop block can be an equilateral polygon or a non-equilateral polygon.
A connecting method of a rotatable flange connecting device is characterized in that: the method comprises the following specific steps:
(1) assembling the flange connecting device: sleeving a rotary flange ring at the groove end of the pipe body, sliding towards the pipe body fixing flange direction until the groove of the pipe body is exposed, then installing an annular stop block in the groove, moving the rotary flange to enable the end face of a boss of an inner ring of the rotary flange to be in contact with the annular stop block, horizontally placing the flange connecting device, installing a threaded retainer ring on an inner ring of the rotary flange, and connecting the two through threads;
(2) connecting the flange connecting device: after the flange connecting device is assembled, firstly, the fixed flange is connected with the flange at one end of the pipeline to be connected, the rotary flange end of the flange connecting device is aligned to the flange at the other end of the pipeline to be connected, the threaded check ring and the rotary flange are rotated, so that the bolt holes in the rotary flange are aligned to the holes in the pipeline flange, and the installation can be completed by inserting bolts.
The invention has the beneficial effects that:
the rotatable flange connecting device is simple in structure, good in practicability, safe and reliable. When the flange pipeline is installed and connected, after the fixed flange is fixed on the pipe body, the rotary flange can rotate at any angle when being butted with other flanges to be connected, the flange bolt holes are simply and quickly centered, the bolts and the nuts are installed, the flange pipeline installation and connection efficiency is improved, and the labor intensity of personnel is reduced. According to the technical scheme, the problem that when the traditional flange pipeline is installed and connected on site, due to the reasons of site limitation and the like, the flange bolt holes cannot be completely centered, so that the connection is difficult and even cannot be achieved is solved. The rotatable flange connecting device can be applied to flange pipeline connection for gas testing and fracturing construction of oil and gas fields and also can be applied to high-pressure flange pipeline connection in other fields.
