Abstract
Novel temperature sensing rod sleeve.Provide good heat-insulation effect, intensity is high, the Novel temperature sensing rod sleeve of long service life.Described sleeve comprises outer wall and inwall, described inwall is located in described outer wall and the upper end of described outer wall and inwall and is connected, the external diameter of described inwall is less than the internal diameter of described outer wall, make the thermal insulation layer forming hollow shape between described outer wall and the wall body of inwall, the inner side of described outer wall is provided with some reinforcements, the inner side of described inwall is provided with at least twice radiating groove, described radiating groove vertically arranges and is communicated to the inside bottom of described inwall, is provided with support ring between the bottom of described outer wall and the bottom of inwall.The effective trap heat of the utility model inwardly spreads, and increases the service life.Owing to being hollow between outer wall and inwall, even if outer wall distortion also can not affect the global shape of inwall, available protecting temperature-sensitive thermocouple.The inner side of inwall is provided with radiating groove, effectively reduces the bulk temperature of sleeve.
Description
Technical field
The utility model relates to the sensing rod for temperature sleeve of test furnace temperature.
Background technology
In process of production, need control in real time temperature, by the sleeve of a sheathed quartzy material in the outside of temperature-sensitive thermocouple on current production line, then sensing rod for temperature is inserted in boiler tube carry out monitoring temperature.The sleeve of quartz material is easily out of shape for a long time in high temperature environments, makes sensing rod for temperature be difficult to insert within boiler tube, sometimes even because colleting deformation causes the damage of temperature-sensitive thermocouple, causes the raising of production cost.
Utility model content
The utility model, for above problem, provides good heat-insulation effect, and intensity is high, the Novel temperature sensing rod sleeve of long service life.
The technical solution of the utility model is: described sleeve is open-topped tubular body, cross section takes the shape of the letter U, comprise outer wall and inwall, described inwall is located in described outer wall and the upper end of described outer wall and inwall and is connected, the external diameter of described inwall is less than the internal diameter of described outer wall, make the thermal insulation layer forming hollow shape between described outer wall and the wall body of inwall, the inner side of described outer wall is provided with some reinforcements, the inner side of described inwall is provided with at least twice radiating groove, and described radiating groove vertically arranges and is communicated to the inside bottom of described inwall;
Support ring is provided with between the bottom of described outer wall and the bottom of inwall.
The height of described reinforcement is the 1/5-1/3 of described insulation thickness.
The degree of depth of described radiating groove is 0.2-0.4mm, and width is 0.4-0.8mm.
Described sleeve adopts ceramic material.
The utility model is provided with outer wall and inwall, and is hollow thermal insulation layer between outer wall and inwall, and effective trap heat inwardly spreads, and is provided with some reinforcements in the inner side of outer wall, improves the intensity of outer wall, extends the service life of sleeve.Owing to being hollow between outer wall and inwall, even if outer wall distortion also can not affect the global shape of inwall, available protecting temperature-sensitive thermocouple.The inner side of inwall is provided with radiating groove, effectively reduces the bulk temperature of sleeve.Meanwhile, sleeve adopts ceramic material, not easy fracture, the sticky boiler tube of high temperature, improves sleeve service life further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the top view of Fig. 1;
In figure, 1 is outer wall, and 11 is reinforcements, and 2 is inwalls, and 21 is radiating grooves, 3 thermal insulation layers, and 4 is support rings.
Detailed description of the invention
The utility model as shown in Figure 1-2, Novel temperature sensing rod sleeve, described sleeve is open-topped tubular body, cross section takes the shape of the letter U, comprise outer wall 1 and inwall 2, described inwall 2 is located in described the outer wall 1 and upper end of described outer wall 1 and inwall 2 and is connected, the external diameter of described inwall 2 is less than the internal diameter of described outer wall 1, makes the thermal insulation layer 3 forming hollow shape between described outer wall 1 and the wall body of inwall 2, for the transmission of trap heat; The inner side of described outer wall 1 is provided with some reinforcements 11, and the inner side of described inwall 2 is provided with at least twice radiating groove 21, and described radiating groove 21 vertically arranges and is communicated to the inside bottom of described inwall 2;
For increasing the bonding strength between described outer wall 1 and inwall 2, between the bottom of described outer wall 1 and the bottom of inwall 2, be provided with support ring 4.
The height of described reinforcement 11 is the 1/5-1/3 of described thermal insulation layer 3 thickness.
The degree of depth of described radiating groove 21 is 0.2-0.4mm, and width is 0.4-0.8mm.
Described sleeve adopts ceramic material.
The utility model is provided with outer wall and inwall, and is hollow thermal insulation layer between outer wall and inwall, and effective trap heat inwardly spreads, and is provided with some reinforcements in the inner side of outer wall, improves the intensity of outer wall.Owing to being hollow between outer wall and inwall, even if outer wall distortion also can not affect the global shape of inwall, available protecting temperature-sensitive thermocouple.Meanwhile, be provided with radiating groove in the inner side of inwall, effectively reduce the bulk temperature of sleeve.
