Abstract
The utility model relates to a high-temperature tube anti-abrasion device of a power plant. A tightening ring is installed on the outside of a high-temperature tube, movable hinges are installed on inner sides of two sides of the tightening ring, fixed hinges are installed on outer sides of the two sides of the tightening ring, an anti-abrasion cover is provided with fixing holes, and tightening bolts are installed on positions wherein the fixed holes correspond to the fixed hinges. The cross section of the anti-abrasion cover and the cross section of the tightening ring are semicircular. According to the high-temperature tube anti-abrasion device, the tightening ring is fixed to the high-temperature tube through the movable hinges, the anti-abrasion cover is fixed to the tightening ring through tightening bolts at the same time, the anti-abrasion cover is not needed to be welded to the high-temperature tube, and the high-temperature tube anti-abrasion device is easy and convenient to maintain and replace.
Description
Technical field
The utility model relates to a kind of bayonet unit.
Background technology
The booster of the superheater of power plant boiler, economizer, water-cooling wall, reheater tube is the principal element that affects the generating set safety and economic operation, except misoperation cause overheated, mainly because ature of coal worsens, contain more sulfate in ash content after making to burn, be deposited on the outer surface of tube wall of boiler high temperature section, it is produced to heat erosion.The mode that general abrasionproof adopts is directly to weld anti-abrasion cover on high-temperature pipe, and this mode one is to change inconvenience, and electric welding also easily damages high-temperature pipe besides.
Summary of the invention
The purpose of this utility model is to provide a kind of power plant's high-temperature pipe shoe be convenient for changing.
The technical solution adopted in the utility model is: power plant's high-temperature pipe shoe, tighten ring is arranged on the high-temperature pipe outside, the both sides installed inside loose-leaf of tighten ring, and fixed page is installed in the outside, have fixing hole on anti-abrasion cover, the lock ring bolt is equipped with in the position of the corresponding fixed page of fixing hole.
The cross section of described anti-abrasion cover and tighten ring is semicircle.
The utility model is fixed on tighten ring on high-temperature pipe by loose-leaf, with the lock ring bolt, anti-abrasion cover is fixed on tighten ring simultaneously, no longer needs anti-abrasion cover is welded on high-temperature pipe, safeguards that replacing is simple and convenient.
