Abstract
The utility model relates to a temperature sensor field especially relates to an aluminium-zinc plating pot thermocouple sheath, a serial communication port, including the sheath body and closing cap nut, the diameter and the length of the sheath body hole of stainless steel 316L material match with the thermocouple, and the one end of the sheath body is equipped with the closing cap nut, and the centre of closing cap nut is equipped with the hole that the signal line was drawn forth, the wall thickness of the sheath body is 12 ~ 14 mm. The connecting thread between the sealing nut and the sheath body is M20 multiplied by 1.5. Compared with the prior art, the beneficial effects of the utility model are that: by adding the external sheath to the thermocouple of the aluminum-zinc plating pot, the corrosion resistance and the heat expansion and cold contraction resistance of the thermocouple are improved, the corrosion of aluminum-zinc liquid and the damage of the thermocouple caused by crusting are reduced, the service life of the thermocouple is prolonged to about 3 months, and the service life of the thermocouple is improved by 3 times.
Description
Technical field
The utility model relates to temperature sensor field, relates in particular to a kind of aluminum-zinc alloy pot thermocouple well.
Background technology
Due to the aluminium zinc solution temperature of cold-rolling galvanization line up to 630 DEG C and corrosivity strong, easily there is the phenomenon that crusts in the edge, pot edge of aluminum-zinc alloy pot, the thermopair that is arranged at present pot edge can only use about one month, just there will be the damage in various degree such as corrosion cracking, crust fracture, cause the increase of spare parts cost, and difficult in maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of aluminum-zinc alloy pot thermocouple well; increase outer protection to aluminum-zinc alloy pot thermopair; improve corrosion resistance and the resistance to ability of expanding with heat and contract with cold of thermopair, reduce the thermopair damage that aluminium liquid zinc corrosion and crust cause, extend the serviceable life of thermopair.
In order to address the above problem, the utility model by the following technical solutions:
A kind of aluminum-zinc alloy pot thermocouple well, comprise jacket body and capping nut, the diameter of the jacket body endoporus of Stainless steel 316 L material mates with thermopair with length, one end of jacket body is provided with capping nut, the centre of capping nut is provided with the hole that signal wire is drawn, and the wall thickness of described jacket body is 12～14mm.
Connecting thread between described capping nut and jacket body is M20 × 1.5.
Compared with prior art, the beneficial effects of the utility model are:
By increasing external jacket to aluminum-zinc alloy pot thermopair, corrosion resistance and the resistance to ability of expanding with heat and contract with cold of thermopair are improved, reduce the thermopair damage that aluminium liquid zinc corrosion and crust cause, is increased to about 3 months the serviceable life of thermopair, improved 3 times.
Brief description of the drawings
Fig. 1 is the utility model example structure schematic diagram.
In figure: 1-jacket body 2-capping nut 3-thermopair
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, it is a kind of aluminum-zinc alloy pot of the utility model thermocouple well example structure schematic diagram, comprise jacket body 1 and capping nut 2, the diameter of the endoporus of the jacket body 1 of Stainless steel 316 L material mates with thermopair 3 with length, one end of jacket body 1 is provided with capping nut 2, and the centre of capping nut 2 is provided with the hole that signal wire is drawn.The wall thickness of jacket body 1 is 12～14mm, is preferably 14mm in embodiment.Connecting thread between capping nut 2 and jacket body 1 is M20 × 1.5.Jacket body 1 material is 316L stainless steel.
When use, sheath with thermopair is inserted to zinc pot and be fixed on the edge, pot edge of aluminum-zinc alloy pot, can carry out temperature survey.
