The utility model discloses a steam turbine drainage pipeline which comprises a fiber reinforced resin layer, a ceramic layer, a foaming layer and a steel layer, wherein the fiber reinforced resin layer is positioned on the innermost layer, the ceramic layer is positioned on the outer layer of the fiber reinforced resin layer, the foaming layer is positioned on the outer surface, deviating from the fiber reinforced resin layer, of the ceramic layer, the foaming layer is internally provided with a plurality of air chambers which are communicated with each other, and the steel layer is positioned on the outer surface, deviating from the ceramic layer, of the foaming layer. This technical scheme is used for solving the problem that current hydrophobic pipeline easily corrodes, breaks and produces the noise.
Description
Technical Field
The utility model belongs to the technical field of a drainage pipeline, and particularly relates to a steam turbine drainage pipeline.
Background
The steam turbine drainage system has the effects of timely removing condensed water in a steam turbine steam inlet pipeline, a steam turbine body and a steam turbine steam extraction pipeline, and avoiding serious damage of the steam turbine caused by the fact that the condensed water enters the steam turbine body, so that the drainage system has important significance for safe operation of a steam turbine unit.
In the drain pipe, because be in under high pressure high temperature's condition, very easily make the steel pipeline produce the corrosion, and the difference in temperature of drain pipe is great, and the steel pipeline is very easily produced the tortoise crackle at long-term shrink expansion process, leads to the easy cracked condition of appearing of steel pipeline, exists a small amount of steam in the drain pipe simultaneously, easily produces the cavitation in the hydrophobic transmission of high pressure, drives the drain pipe vibration simultaneously, produces great noise.
SUMMERY OF THE UTILITY MODEL
Aiming at the technical problems, the utility model provides a steam turbine drainage pipeline to solve the problems that the existing drainage pipeline is easy to rust, crack and generate noise.
The utility model provides a steam turbine drainage pipeline which comprises a fiber reinforced resin layer, a ceramic layer, a foaming layer and a steel layer, wherein the fiber reinforced resin layer is positioned on the innermost layer, the ceramic layer is positioned on the outer layer of the fiber reinforced resin layer, the foaming layer is positioned on the outer surface, away from the fiber reinforced resin layer, of the ceramic layer, the foaming layer is provided with a plurality of air chambers which are communicated with each other, and the steel layer is positioned on the outer surface, away from the ceramic layer, of the foaming layer.
Further, a pressure sensor is arranged inside the fiber reinforced resin layer.
Further, the outer layer of the steel layer is provided with a vibration sensor.
The steam turbine drainage pipeline is sequentially provided with the fiber reinforced resin layer, the ceramic layer, the foaming layer and the steel layer from inside to outside, wherein the fiber reinforced resin layer and the ceramic layer have better corrosion resistance, the steel layer can be effectively isolated from high-temperature and high-pressure hot water, the steel layer is prevented from being rusted by the hot water, and meanwhile, the ceramic layer and the steel layer have better strength supporting effect, so that the integral strength of the steam turbine drainage pipeline is ensured; the foaming layer plays a role in buffering, can buffer the volume expansion change between the ceramic layer and the steel layer and avoids cracks; on the other hand, the noise isolation device plays a role in isolating noise and effectively isolates the noise problem generated by gas in the pipeline.
