Anticorrosion plug screw alarm device for ships

Abstract

The invention relates to an anticorrosion plug screw screw alarm device for ships, mainly comprising an anticorrosion plug screw and an alarm controller. The anticorrosion plug screw is mounted on a close over of a ship condenser and comprises a joint nut, a joint, a plug screw and an anticorrosion block, one end of the anticorrosion block is tightly screwed in an internal threaded hole at one end of the plug screw trough the thread, one end of the plug screw is tightly screwed on the close over of the ship condenser, an external threaded hole at the other end of the plug screw is in threaded connection with one end of the joint, the other end of the joint is in threaded connection with the joint nut, the anticorrosion block, the plug screw, the joint and the joint nut are internally provided with four leakage holes which are mutually communicated, the first leakage hole is arranged at one end of the anticorrosion block and is not communicated with the other end of the anticorrosion block, and the fourth leakage hole is connected with a hydraulic controller and an alarm controller through a conveying pipeline. The invention has simple and compact structure, is convenient to assemble and maintain, can alarm a worker to replace the anticorrosion plug screw in time, lessen the seawater corrosion to the condenser pipeline and prolong the service life of the condenser.

Description

technical field [0001] The invention relates to an alarm device for a marine anti-corrosion screw plug. Background technique [0002] Most of the existing marine air-conditioning condensers are cooled by seawater. Since seawater is corrosive to metal materials, sacrificial anodes are used in the condenser to reduce the corrosion of seawater on metal materials and prolong the service life. Generally, the anti-corrosion screw plug (GB3009-82) is used as a sacrificial anode to achieve this purpose. The anti-corrosion screw plug must be replaced periodically to ensure the normal use of the cooling device, but the replacement cycle of the anti-corrosion screw plug is based on experience. In an approximate period of time, the actual use of anti-corrosion screw plugs is closely related to the quality of seawater. In different sea areas, the corrosion ability of seawater to metal materials is different and irregular, resulting in inaccurate replacement cycles for anti-corrosion scre...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems in the prior art that the anti-corrosion screw plug of the marine air-conditioning condenser is replaced periodically based on the accumulation of human experience, if the replacement is not timely, the anti-corrosion screw plug will easily fail, and the corrosion of the condenser will cause damage to the marine refrigeration system. The present invention provides a It is a marine anti-corrosion screw alarm device that can remind people to replace the anti-corrosion screw plug in time, reduce the corrosion of seawater on the condenser pipe, and prolong the service life of the condenser
