Description
Technical field
The utility model relates to a kind of warning device of corrosion protection plug screw peculiar to vessel.
Background technology
The most of seawater that adopts of existing air-conditioning condenser peculiar to vessel cools off, because seawater has corrosivity to metal material, so adopt sacrificial anode to reduce seawater in the condenser Corrosion of Metallic Materials is increased the service life.The general corrosion protection plug screw (GB3009-82) that adopts reaches this purpose as sacrificial anode, the corrosion protection plug screw must periodically more bring the normal use that guarantees cooling device, but the replacement cycle of corrosion protection plug screw is to accumulate a whenabouts that draws by rule of thumb, actual corrosion protection plug screw operating position has inseparable relation with seawater quality, in different waters, seawater is different and do not have a rule to the Corrosion of Metallic Materials ability, cause the experience replacement cycle of corrosion protection plug screw inaccurate, the corrosion protection piece that is prone to the corrosion protection plug screw is washed out by seawater after being corroded and becoming flexible, or the corrosion protection piece back that is corroded is not in time changed and is caused seawater to begin to corrode the condenser internal pipeline, condenser is fragile to be scrapped, seawater enters " heart component "-refrigeration compressor that freon refrigeration system burns the central air-conditioning unit when badly damaged, cause the paralysis of marine refrigeration system, make troubles to crewman's work and life.
Summary of the invention
In order to solve the corrosion protection plug screw of changing air-conditioning condenser peculiar to vessel in the prior art according to the people for the experience accumulation cycle, changing the untimely corrosion protection plug screw that easily causes lost efficacy, the corrosion condenser causes deficiencies such as marine refrigeration system damage, the utility model provides a kind of can in time remind artificial replacing corrosion protection plug screw, reduce the corrosion of seawater, prolong the condenser corrosion protection plug screw warning device peculiar to vessel in service life condenser tubes.
The technical solution adopted in the utility model is: a kind of corrosion protection plug screw warning device peculiar to vessel, mainly comprise corrosion protection plug screw and alarm controller, the corrosion protection plug screw is installed in the capping of condenser peculiar to vessel, its technical characterstic is that described corrosion protection plug screw comprises collar nut, joint, plug screw and corrosion protection piece, one end of corrosion protection piece is in screw thread is tightened against the internal thread hole of plug screw one end, above-mentioned plug screw one end is tightened in the condenser capping peculiar to vessel, external screw thread aperture thread connecting joint one end of the plug screw other end, the joint other end is through the thread connecting joint nut; Be respectively equipped with first, second, third and fourth leak that is interconnected in corrosion protection piece, plug screw, joint and the collar nut, first leak holes is located at an end of above-mentioned corrosion protection piece and is not communicated with the other end of corrosion protection piece, second and third, four leak phase intercommunicating porosities; The 4th leak of described collar nut connects hydraulic controller through transfer pipeline, and hydraulic controller connects alarm controller.The corrosion protection plug screw is installed in the condenser capping peculiar to vessel, contact with sea water in the corrosion protection piece of corrosion protection plug screw and the condenser, seawater preferentially corrodes the corrosion protection piece, when corrosion protection piece heavy corrosion causes first leak of corrosion protection piece to be communicated with the condenser inner chamber, seawater flows to hydraulic controller by first, second, third and fourth leak and transfer pipeline successively, hydraulic controller changes into signal and sends to alarm controller, in time reminds operating personnel in time to change by alarm controller.
Further, be provided with gasket seal between described corrosion protection piece and plug screw, guarantee sealing between corrosion protection piece and plug screw, do not reveal.
Again further, described alarm controller is provided with alarm lamp and buzzer.
After adopting above technical scheme, the beneficial effect that the utility model reaches is: the corrosion protection plug screw of being made up of collar nut, joint, plug screw and corrosion protection piece is installed in the capping of condenser peculiar to vessel, change the traditional welding connected mode, the whole employing is threaded mutually, replacing, convenient disassembly; The corrosion protection piece is corroded in condenser, once seriously corroded can in time be reported to the police alarm controller, when first leak of corrosion protection piece is communicated with the condenser inner chamber, seawater flows to hydraulic controller by first, second, third and fourth leak and transfer pipeline successively, hydraulic controller changes into signal and sends to alarm controller, the alarm lamp and the buzzer of alarm controller send sound and light alarm, in time remind operating personnel in time to change.
The utility model adopts the corrosion protection piece corrosion back of the corrosion protection plug screw of condenser to be communicated with corrosion protection plug screw internal leakage aperture transfer pipeline seawater signal transmission alarm controller is reported to the police, it is simple in structure, compact, it is convenient to assemble, safeguard, can in time remind artificial replacing corrosion protection plug screw, reduce the corrosion of seawater, prolong condenser service life condenser tubes.
