Abstract
The utility model discloses a temperature sensor sealing structure which includes a stud, a nut and a locating ring; one end of the stud is connected with a tested device and the other end of the stud is connected with the nut; a thread hole for a sensor lead to penetrate is arranged coaxially along the inside of the stud; one end of the stud matched with the nut is provided with an inner locating chamfer; one end of the nut is provided with an inner thread matched with the stud and the other end is provided with a thread hole for a sensor lead to penetrate coaxially along the inside of the stud; an inner cavity is arranged between the inner thread and the thread hole; the inner end of the thread hole is provided with a locating chamber; the outer circle at the two ends of the locating ring is provided with a chamber which is matched with the locating chamber of the thread hole of the nut and the inner locating chamber of the stud. The temperature sensor sealing structure is characterized in that a circle of groove is arranged on the outer circle surface of the locating ring; and the locating ring is welded together with the sensor lead at the groove. The temperature sensor sealing structure has good sealing effect, can improve the temperature measurement accuracy of the temperature sensor, is convenient to be installed, and is convenient to improve the working efficiency.
Description
Technical field
The utility model relates to the temperature sensor technical field, specifically is a kind of temperature sensor hermetically-sealed construction.
Background technology
Existing temperature sensor comprises stud bolt, nut, locating ring; Stud bolt one end is connected with equipment under test, and the other end is connected with described nut; The through wires hole that passes for sensor lead is set in the stud bolt vertically; Location chamfering in an end that cooperates with nut is provided with; The internal thread that nut one end setting cooperates with stud bolt, the other end are provided with the through wires hole that passes for sensor lead vertically, are provided with an inner chamber between internal thread and through wires hole; The inner end of through wires hole is provided with the location chamfering; The cylindrical at locating ring two ends is provided with chamfering; Match with the location chamfering of the through wires hole of nut, the interior location chamfering of stud bolt respectively.
In case cooperate not closely between locating ring inwall and the sensor lead outside surface, poor sealing will be leaked gas.Gas is spilt by the gap between through wires hole, locating ring inwall and the sensor lead outside surface of stud bolt, the through wires hole of nut.Gas leakage can influence thermometric degree of accuracy, and the performance reliability of temperature sensor is reduced.
In addition, because locating ring is that activity is nested with on sensor lead, between the two can be movable, so install cumbersomely, when being connected, need the adjustment sensor lead with equipment, waste time and energy, influence work efficiency.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of temperature sensor hermetically-sealed construction, and its good sealing effect can improve the temperature survey degree of accuracy of temperature sensor.
The technical scheme that its technical matters that solves the utility model adopts is: this temperature sensor hermetically-sealed construction comprises stud bolt, nut, locating ring; Stud bolt one end is connected with equipment under test, and the other end is connected with described nut; The through wires hole that passes for sensor lead is set in the stud bolt vertically; Location chamfering in an end that cooperates with nut is provided with; The internal thread that nut one end setting cooperates with stud bolt, the other end are provided with the through wires hole that passes for sensor lead vertically, are provided with an inner chamber between internal thread and through wires hole; The inner end of through wires hole is provided with the location chamfering; The cylindrical at locating ring two ends is provided with chamfering; Match with the location chamfering of the through wires hole of nut, the interior location chamfering of stud bolt respectively; One circle groove is set on the outer circumference surface of described locating ring, welds together at described locating ring of this groove and described sensor lead.
The beneficial effects of the utility model are: it is owing to weld together between locating ring and the sensor lead, thus cut off the passage that gas leaks outside, thus avoided having improved the reliability of temperature sensor because of gas leakage influences measuring accuracy; In addition, locating ring and sensor lead are welded as a whole, and it is also convenient to install, and is convenient to increase work efficiency.
