A stabilizing device for eliminating vibration of bellows compensator

Abstract

The invention discloses a stabilizer for eliminating corrugated expansion joint vibration. The stabilizer comprises a steam pipe provided with an insulation layer and is characterized in that the steam pipe is provided with a thrust ring, a baffle and a force bearing ring, the insulation layer is arranged on the steam pipe on two sides of the baffle, a casing pipe is arranged outside the insulation layer, the baffle is a ring sleeving the steam pipe, the excircle of the ring is larger than the diameters of the thrust ring and the force bearing ring, the baffle is in sliding connection with the steam pipe, the thrust ring and the force bearing ring are sleeves arranged on two sides of the baffle, and the thrust ring and the force bearing ring are fixedly connected with the steam pipe and the casing pipe respectively through wing plates. Compared with the prior art, the stabilizer limits the compensation of a corrugate pipe after initial thermal elongation, prevents the corrugated pipe from continuing to expand after initial thermal elongation, avoids corrugated pipe vibration, and effectively prevents an expansion joint corrugated pipe in a heat supply network from being damaged due to premature fatigue. The stabilizer is easy in structure and convenient to manufacture and mount, and further improves the safe operation and economic benefits of pipeline networks.

Description

technical field [0001] The invention relates to the technical field of heat pipe networks, in particular to a stabilizer for eliminating vibration of a bellows compensator. Background technique [0002] The heat pipe network, especially the industrial steam transmission and distribution pipe network, is developing rapidly. The temperature of the medium in the pipe network is different from the ambient temperature. For example, industrial steam, the medium temperature is between 150°C and 300°C, and the pipe temperature is close to the medium temperature. Pipes are mostly made of ordinary carbon steel. The temperature range of the medium and the physical properties of steel determine that the pipes transporting industrial steam need to solve the problem of thermal expansion and contraction, so the heating network needs to be compensated. The metal bellows compensator is widely used in the heating network due to its simple structure and convenient use. The metal bellows compe...

Problems solved by technology

Combining several small expansions can be converted into a full expansion. Because the frequency of steam temperature fluctuations in the heating network is very high, the life of the compensator is still significantly affected, and it is often scrapped earlier than the pipe network.
