Embodiment
As shown in Figure 8, stainless steel elbow comprise bend 1 and from the end of bend 1 along the outward extending straight sections 2 of straight line, the utility model is exactly the heating unit that the bend 1 to stainless steel elbow carries out solution treatment.
Below in conjunction with accompanying drawing the utility model is described in further details:
As shown in Figure 1, in the present embodiment, the rectangular parallelepiped casing 3 that is used to hold stainless steel elbow bend 1 is fastened with lower box 32 by upper box 31 and forms, on two long side surfaces that upper box 31 and lower box 32 amalgamations form, respectively offer two and go out pore 6, respectively offer one on four angles that described side forms and go out pore 6, the described center that goes out pore 6 all is positioned on upper box 31 and the lower box 32 handing-over lines so that the stainless steel elbow of differently curved angle is positioned over casing 3.
Most important when heating in the present embodiment to each point temperature control in the casing 3, therefore upper box 31 be parallel to horizontal plane upper surface four angles and in respectively be provided with the thermopair socket 7 that is used to plug thermocouple thermometer in the heart.During heating the thermocouple thermometer (not shown) is plugged in thermopair socket 7, to monitor the temperature of each point in the casing 3 at any time.
Shown in Fig. 2,3, in the present embodiment, heating is by the ceramic frame 41 that is arranged on casing 3 inside and adds thermalloy 42 and realize, respectively be fixed with a ceramic frame 41 at described upper box 31 and lower box 32 inside, each ceramic frame 41 equal intervals is provided with nine of being used to heat and adds thermalloy 42, and the described thermalloy 42 that adds is parallel to each other.Described ceramic frame 41 and add the major portion that thermalloy 42 has constituted heating component 4.
