Abstract
The utility model relates to a kind of anti-interior leaky armoured thermocouple or thermal resistance; comprise terminal box (1) and armouring inner core (3); described armouring inner core comprises metal sleeve (3b) and is positioned at thermo wires or the resistance thermometer clement (3a) of metal sleeve; described thermo wires or resistance thermometer clement are connected with the binding post be arranged in terminal box (4); the periphery of described armouring inner core is provided with outside protective pipe (2); the tie point of thermo wires or resistance thermometer clement and binding post is welded on the inwall of outside protective pipe, and described outside protective pipe is connected with terminal box.The utility model improves the sealing of product, effectively prevent high temperature and high pressure gas and is outwards sprayed by terminal box and let out, and solves the problem of existing product inner structure sealing difference; The magnesia powder added is flour, makes product have shockproof properties, extends the serviceable life of product.
Description
Technical field
The utility model relates to a kind of thermoelectricity occasionally thermal resistance, especially, relates to a kind of anti-interior leaky armoured thermocouple or thermal resistance, belongs to thermometric product technical field.
Background technology
Thermopair and thermal resistance all as the contact temperature-measuring device in temperature survey, are used widely in the industry.At present; be used in high pressure or wash away the thermoelectricity occasionally thermal resistance in workshop; because workplace vibrations often cause comparatively greatly the protection tube of thermoelectricity occasionally thermal resistance to break; easily directly damage product on the one hand; if inner structure sealing is bad on the other hand; also easily cause the high temperature and high pressure gas in protection tube outwards to be sprayed by terminal box to let out, there is very large potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of anti-interior leaky armoured thermocouple or thermal resistance, and its protection tube is combined with terminal box firmly, can effectively avoid protection tube to be break.
The technical scheme that the utility model solves the problem is as follows:
A kind of anti-interior leaky armoured thermocouple or thermal resistance, comprise terminal box and armouring inner core, described armouring inner core comprises metal sleeve and is positioned at thermo wires or the resistance thermometer clement of metal sleeve, and described thermo wires or resistance thermometer clement are connected with the binding post be arranged in terminal box, it is characterized in that:
The periphery of described armouring inner core is provided with outside protective pipe, and the tie point of described thermo wires or resistance thermometer clement and binding post is welded on the inwall of outside protective pipe, and described outside protective pipe is connected with terminal box.
Described outside protective pipe with between terminal box for being threaded.
As further improving be, described outside protective pipe with between terminal box for welding or being threaded.
In order to play antihunt action, between described outside protective pipe and armouring inner core, be filled with magnesia powder.
As preferably, the thermo wires of described armouring inner core adopts Graduation Number to be one in K, N, E, J, T.
The thermal resistance original paper of described armouring inner core is preferably platinum resistance thermometer sensor, original paper or copper thermistor original paper.
Described outside protective pipe is stainless steel outside protective pipe.
Compared with prior art, the beneficial effects of the utility model are, in described armouring, the tie point of in-core thermo wires or resistance thermometer clement and binding post is welded on the inwall of outside protective pipe, and after outside protective pipe and terminal box are fixed and are connected, the sealing property of thermoelectricity occasionally thermal resistance is increased greatly, effectively prevent high temperature and high pressure gas outwards to be sprayed by terminal box and let out, solve the problem of existing product inner structure sealing difference; Because magnesia powder is flour, make product have shockproof properties, extend the serviceable life of product.

As optimal way, described outside protective pipe with between terminal box for being threaded.
Shown in composition graphs 3 and Fig. 4, in order to play antihunt action, between described outside protective pipe and armouring inner core, be filled with magnesia powder 3c.
As preferably, the thermo wires of described armouring inner core adopts Graduation Number to be one in K, N, E, J, T.
The thermal resistance original paper of described armouring inner core is platinum resistance thermometer sensor, original paper or copper thermistor original paper.
Described outside protective pipe is stainless steel outside protective pipe.
In the utility model armouring, the tie point of in-core thermo wires or resistance thermometer clement and binding post is welded on the inwall of outside protective pipe, and after outside protective pipe and terminal box are fixed and are connected, the sealing property of thermoelectricity occasionally thermal resistance is increased greatly, effectively prevent high temperature and high pressure gas outwards to be sprayed by terminal box and let out, solve the problem of existing product inner structure sealing difference; Because magnesia powder is flour, make product have shockproof properties, extend the serviceable life of product.
