Abstract
The utility model discloses a high temperature resistant wear-resisting thermometer sleeve, including metal sleeve, protective sheath, thermometer sleeve's measuring end is corundum or the wear-resisting head of carborundum, and this wear-resisting head is equipped with the screw thread of being connected with metal sleeve, and connecting thread is sealed with gluing, constitutes whole sleeve pipe behind the sealing connection, and the protective sheath is fixed outside wear-resisting head and metal sleeve. The utility model discloses wear resistance is good, long service life.
Description
Technical Field
The utility model relates to a thermometer sleeve pipe, especially a can measure high temperature and long service life's high temperature resistant wear-resisting thermometer sleeve pipe.
Background
The device such as burn burning furnace, riser, boiler has special abominable operational environment, have high temperature corrosive substance in the device, the thing granule of burning, do not have characteristics such as fly ash, catalyst granule, medium high velocity of flow, the thermometer sleeve pipe that uses requires wear-resisting, current thermometer sleeve pipe generally adopts alloy sleeve pipe skin build-up welding, spraying wear-resisting alloy or adopts cast wear-resisting head or general ceramic class sleeve pipe, above-mentioned sleeve pipe is easily scoured and worn out, high temperature hot corrosion or erode the fracture when using, life is shorter, will damage and need to change in general half a year, it does not reach a maintenance cycle to park, if change must the device stop, very big reduction productivity effect like this. There is therefore a need for a thermo-well tube that can be used in the above-described device operating conditions effectively for a long period of time.
SUMMERY OF THE UTILITY MODEL
For the problem that prior art exists more than solving, the utility model provides a high temperature resistant wear-resisting thermometer sleeve pipe.
The utility model discloses can solve through following technical scheme:
the high-temperature-resistant and wear-resistant thermometer sleeve comprises a metal sleeve and a protective sleeve, wherein the measuring end of the thermometer sleeve is a corundum or silicon carbide wear-resistant head, the wear-resistant head is provided with a thread connected with the metal sleeve, the connecting thread is sealed by glue, the integral sleeve is formed after the sealing connection, and the protective sleeve is fixed outside the wear-resistant head and the metal sleeve.
Further, the protective sleeve is fixed outside the wear-resistant head and the metal sleeve.
Further, the protective sleeve is fixed by screws.
Further, the metal sleeve further comprises a flange, and the upper end of the metal sleeve is connected with the flange.
Furthermore, the upper end of the metal sleeve is provided with threads, and the metal sleeve and a matched nut form a connecting assembly.
Advantageous effects
The utility model is thick-wall corundum or silicon carbide, which is not easy to break; the thick-wall corundum or silicon carbide sleeve can be connected with the metal sleeve through threads, so that the connection is firmer and more reliable; the protective sleeve is additionally arranged and fixed on the outer sides of the sleeve and the wear-resistant head, so that the influence of vibration or transverse shearing force on the service life of the wear-resistant head can be reduced. The utility model discloses wear resistance is good, and the metal sleeve is difficult for wearing and tearing, and corrosive medium can not enter into in the metal sleeve.
