[0026] Working principle: When the pressure transmitter is used for matching installation with the high-pressure pipeline, the reinforcement component 7 is separated from the screw rod 5 and the support rod 6, and the rotating ring 709 and the fixed ring 706 are in a rotating and separated state. The installation rod 1 is screwed on the installation position of the high-pressure pipeline to complete the matching installation. After the installation and fixation of the installation rod 1 is completed, the anti-slip sleeve 702 is screwed to drive the threaded sleeve 701 to rotate and sleeve on the outside of the screw rod 5.

The rotating ring 709 can rotate freely through the support of the rotating block 708. The rotating ring 709 is rotated upward and also sleeved on the outside position of the high-pressure pipeline. The bolt 712 is inserted and the screw is screwed. The nut 713 can clamp and fix the first splicing block 710 and the second splicing block 711, so that the fixed ring 706 and the rotating ring 709 can be sleeved on the outer side of the high-pressure pipe and clamped. At this time, through the connection of the fixed sleeve block 4, the fixed ring 706 and the rotating ring 709 can be sleeved on the outside of the high-pressure pipe, which can limit the installation position of the support seat 2, so that the support seat 2 cannot rotate, which can avoid the internal thread of the installation position of the mounting rod 1 and the high-pressure pipe from loosening due to external vibration, thereby improving the stability of the installation and use of the pressure transmitter.
