Problems solved by technology

This signal sending method can only be known through the crew inspection, and cannot be connected to the information alarm system
This is not conducive to the continuous and stable protection of the protected equipment, and is not conducive to the realization of automation of system operation and maintenance. It may even cause serious leakage of the pipeline due to excessive corrosion of the sacrificial flange.

Abstract

The invention discloses a sacrificial flange, which includes a flange body, a piston mechanism and a detection device. The piston mechanism includes a casing and a piston part. One end of the casing is provided with a butt hole communicating with the failure hole. , the other end of the housing is provided with an inner cavity for accommodating the piston member, the butt hole communicates with the inner cavity, and the detection device is connected with the housing; the housing of the piston mechanism The body is set on the failure hole of the flange body. When the flange body has not failed, the failure hole is not connected with the high-pressure water in the pipeline, and the piston mechanism is not affected by the pressure of the water pressure, and no displacement action will occur. When the flange body fails At this time, the high-pressure water in the pipeline enters the inner cavity of the shell through the failure hole, and the piston part is pushed by the water pressure to move, and the detection device obtains the movement and converts it into an electronic signal, which is conducive to timely maintenance and replacement. Sacrifice the flange.

Description

technical field [0001] The invention relates to the technical field of ship fittings, in particular to a sacrificial flange. Background technique [0002] During the operation of the ship, most of the heat generated by the equipment is taken away by the seawater through heat exchange. The seawater system, as the main body of the ship’s heat exchange, is always in operation, but the seawater is highly corrosive, so seawater pipelines and piping The equipment connected to the road has become the hardest hit area of ​​corrosion. According to the summary of the quality assurance sheet of the pipeline system after the delivery of the ship, most of them are corrosion of the pipeline. At the same time, there are traces of corrosion on some equipment interfaces. Advanced measures such as paint and internal plastic coating to treat the inner surface of the pipeline still cannot prevent seawater from corroding the pipeline and equipment. In this case, the use of sacrificial anodes to...
