Through adopting above-mentioned technical scheme, equal fixed connection between reset spring, connecting rod, the instruction ring, when fastening bolt outwards screwed out, reset spring can relax, and connecting rod and instruction ring can rise along with fastening bolt's spiral shell play, and the explanation has been can the slip fastening bolt when instructing the ring and breaking away from fastening bolt, need not to screw out fastening bolt is whole.
Preferably, the planes of the first flange and the second flange are both provided with a circle of annular red copper plating layer for high-pressure sealing.
Through adopting above-mentioned technical scheme, the setting of annular red copper cladding material, on the one hand can improve the reliability of pipeline seal under the high temperature high pressure condition, and on the other hand is difficult ageing, also can not scatter with conventional sealed pad or sealing washer because annular red copper cladding material is to be connected as an organic whole with pair blind flange, consequently its performance is better.
In summary, the invention mainly has the following beneficial effects:
the height detection assembly can prevent the bolt from being completely removed when the bolt is replaced, so that the working efficiency is improved; the position of the bolt can be observed through the scale marks, so that the bolt is convenient to identify; all fixed connection between reset spring, connecting rod, the instruction ring, when fastening bolt outwards screw out, reset spring can relax, and connecting rod and instruction ring can rise along with fastening bolt's spiral shell is gone out, explains when instructing the ring and breaking away from fastening bolt that fastening bolt has can slide, need not to screw out fastening bolt is whole.
