Abstract

The invention belongs to the technical field of leaking stoppage devices, and particularly relates to a steam turbine steam guide pipe flange sealing device. The steam turbine steam guide pipe flange sealing device comprises an upper clamping body and a lower clamping body, the upper clamping body and the lower clamping body are both semicircular, and glue injection grooves and connecting holes communicating with the glue injection grooves are formed in the upper clamping body and the lower clamping body; the upper clamping body and the lower clamping body are connected through fixing bolts, corresponding connecting lugs are arranged at the two ends of the upper clamping body and the two ends of the lower clamping body, hook bodies are fixed to the connecting lugs of the upper clamping body, and the connecting lugs of the lower clamping body can be supported through the hook bodies; and an axial pressing assembly is arranged on the upper clamping body and / or the lower clamping body. The hook bodies are arranged, the connecting lugs of the lower clamping body can be supported through the hook bodies, and therefore integral combination can be conveniently realized only by one operator in the operation process; and by arranging the axial pressing assembly, the whole body can be prevented from deviating in the axial position.

Description

technical field [0001] The invention belongs to the technical field of leak plugging devices, and in particular relates to a flange sealing device for a steam guide pipe of a steam turbine. Background technique [0002] The steam from the boiler flows through the main steam valve and the regulating valve and flows into the turbine cylinder through four inlet pipes connecting the regulating valve and the high-pressure cylinder. The intake pipe is connected to the cylinder by two intake sleeves on the upper cylinder and two intake sleeves on the lower cylinder. The upper part of the steam inlet pipe has a pair of flanges, allowing maintenance personnel to uncover the upper half of the cylinder after removing the pair of flanges. Each flange is composed of concave and convex flanges and connected by bolts. It contains spiral wound gaskets for sealing flanges. [0003] The upper half of the high and medium pressure cylinder can be uncovered after the steam pipe flange is disa...
