Abstract

The utility model relates to a gap front-mounted type explosion-proof thermocouple (thermal resistance), which is characterized in that the lower end of a terminal board in a terminal box is provided with a detachably connected built-in protective sleeve barrel, the inner side of the sleeve barrel is provided with a compression spring and a wire, the lower part of the compression spring is connected with a temperature measurement element and is inserted into a protective tube, a cylinder explosion-proof structure is arranged on an inlet of the protective tube, and the contact of the temperature measurement element and the bottom part of the protective tube is kept.

Description

Gap forward type flame proof thermopair (resistance)
The utility model relates to the temperature measurement technology field, belongs to a kind of thermopair (resistance) of explosion-proof occasion specifically.
Be explosion-proof between thermopair (resistance) the terminal box cavity of flame proof occasion and the protection tube cavity both at home and abroad at present; in the junction of terminal box and terminal block the cylinder blast resistance construction is set mostly; in order to reach the electric insulation requirement; employing " the anti-trace of letting out " plastics is preferably made, but the thermal expansivity of plastics is bigger, and easily aging; not only make flame proof gap instability; influence explosion-proof performance, and kill easily, make loading and unloading bring difficulty.
The preposition cylinder explosion separation structure of the purpose of this utility model at the protection tube inlet; improve explosion-proof performance; and adopt the built-in elasticity cold junction of movable technology; not only the flame proof gap is stable; and loading and unloading smoothly, obtains a kind of gap forward type flame proof thermopair (resistance) of thermal response preferably and resistance to shock simultaneously.
For finishing the technical scheme that above-mentioned purpose is taked: terminal block 2 lower ends in the terminal box 11 are provided with the built-in protection sleeve 5 of active connection; compression spring 3 and lead 4 are established in sleeve 5 inboards; compression spring connects temperature element 63 times; measuring sensor 6 inserts protection tube 8; the stainless steel sleeve 7 of pipe flame proof is set in the porch; the bottom of temperature element 6 contacts with protection tube 8, carries out the cylinder flame proof by pipe stainless steel sleeve 7 between protection tube cavity 10 and the terminal box cavity.
The utility model is owing to adopt the warm element be welded with stainless steel sleeve 7 and the cylinder explosion separation structure is formed in the hole of the porch of protection tube 8; make dimensional accuracy higher, even under the violent or corrosive environment effect, also can keep stable dimensions in temperature variation; therefore, explosion-proof reliability height.Take elasticity cold junction parts simultaneously, promptly terminal block 2 takes flexible electric to be connected with temperature element 6, will measure warm element 6 by compression spring and hold out against bottom in protection tube, and thermal response and shock resistance can obtain bigger raising like this.
The utility model embodiment is described in detail in conjunction with figure.
Fig. 1 is the utility model structural drawing.
According to shown in Figure 1; below the cavity internal wiring terminal of terminal box 11 and terminal block 2, establish built-in protection sleeve 5; protection sleeve 5 is active the connection with temperature element 6; sleeve 5 inboards are provided with the compression spring 3 and the lead 4 that can keep the fiduciary level that temperature element 6 bottoms and protection tube bottom connection touch; compression spring 3 lower ends connect temperature element 6; temperature element 6 inserts protection tube 8; at the inlet relative position place soldering stainless steel cover 7 of temperature element 6 with protection tube 8; guarantee protection tube cavity 10 and the requirement of terminal box cavity flame proof; constitute the circle flame proof, guarantee that at last the bottom of temperature element 6 contacts with protection tube 8 bottoms.
