Preferably, a pressure sensor is arranged between the outer flanging and the end face of the flange, the pressure sensor is electrically connected with a controller, and the controller is electrically connected with a pressing signal device. By adopting the arrangement, the pressure at the flanging part can be measured through the pressure sensor, and when the pressure reaches the preset threshold value of the controller, the compressing signal device sends out a signal, so that the flanging part is ensured to be compressed, and the leakage of the transported medium is avoided.
The outer edge of the outer flanging is provided with a radial electrode embedding hole, two electrodes are arranged in the electrode embedding hole, and the electrodes, a power supply and an alarm device form a loop. By adopting the arrangement, when the lining is damaged, the liquid medium can enter the electrode embedding hole through the gap of the lining, and the loop is conducted, and the alarm device sends out a signal to remind a worker to overhaul.
The utility model has the advantages as follows:
firstly, the method comprises the following steps: the lining can effectively isolate the corrosion of a medium to the flange and the leakage of the common stainless steel flange, thereby meeting the requirements of good sealing and corrosion prevention when the high-corrosive medium is transported.
II, secondly: the lining is of an integral structure, the bonding strength of the lining and the flange can be improved,
thirdly, the method comprises the following steps: the flanging at least positioned at one end of the inner hole is detachably connected with the lining, so that the lining is convenient to arrange.
