Abstract

The steam turbine drainage device comprises a fixed connector, the fixed connector comprises a connecting base, the connecting base is provided with a connecting flange, and the connecting flange is fixedly connected to a steam turbine drainage opening; the movable connector comprises a connector connected with the connecting base in a matched mode, the connector is provided with a second through hole penetrating through the connector, a sliding groove extending in the radial direction is formed in the side face of the second through hole, and a sliding block is arranged in the sliding groove. The connecting seat is sleeved with an annular ring, a deep groove is formed in the inner side face of the annular ring, the deep groove is annular, and the fixing pin is embedded into the deep groove; the steam turbine drainage port is connected with the drainage pipeline through the fixed connector and the movable connector, rapid assembly and disassembly of the steam turbine drainage pipe can be achieved, the assembly production efficiency and actual use convenience of the drainage pipe are greatly improved, and the problem that a conventional steam turbine drainage pipe is inconvenient to assemble and disassemble is solved.

Description

technical field [0001] The invention relates to the field of steam turbine drainage, in particular to a steam turbine drainage device. Background technique [0002] The small steam turbine in a thermal power plant refers to the equipment used to supply electric energy to the auxiliary equipment of the large steam turbine, such as the boiler feed water pump, to reduce the power consumption rate of the plant, convert the secondary steam into electric energy, and reduce the total loss of the power plant. Drainage is the condensed water produced by steam in the pipeline due to the pressure and temperature drop. Drainage should be discharged in time, otherwise it will not only absorb the heat of steam in the pipe, affect the flow of steam, but also cause serious water hammer phenomenon and cause serious consequences. The existing steam turbine drainage heat well has defects in drainage, and the drainage efficiency is low, which is not conducive to the current rapid drainage requ...
