AI Technical Summary
Existing stainless steel thermometer sleeves are prone to forming polymer clumps in the polymerization reactor, affecting measurement accuracy. Furthermore, the thermometer rod is prone to collision with the inner wall of the sleeve during installation, leading to wear.
The thermometer sleeve is made of high-temperature alloy material, with a sliding groove and a support ring on the inner wall. The support ring is composed of an alloy steel ring and a rubber ring. During installation, the slider avoids collisions, and a flange connection plate and sealing gasket are used to improve the ease of installation and sealing.
This avoids scratches and polymer scarring on the thermometer sheath surface, improves measurement accuracy and corrosion resistance of the sheath, and extends its service life.
