Problems solved by technology

[0002] The steam inlet regulating valve of the steam turbine is used to adjust the air intake of the steam turbine. The steam inlet and exhaust process of the steam distribution mechanism used by the existing steam inlet regulating valve is relatively slow, and the activities between the parts are not flexible and the stability is not high. At the same time The air pressure inside the valve body cannot be adjusted at any time, there are certain hidden dangers, and once the dust enters the valve body, it is easy to cause the parts to jam, and the safety is not high

Abstract

The invention discloses a safe steam distribution mechanism for a steam inlet regulating valve of a steam turbine, which comprises a regulating valve body, a lower valve cover, an upper valve cover, a main steam inlet mechanism, a lower pressure mechanism, an auxiliary steam inlet mechanism and a pressure regulating mechanism , the inside of the regulating valve body is fixedly connected with an arc-shaped baffle, and the inside of the regulating valve body is provided with an exhaust chamber on one side of the arc-shaped baffle. The steam inlet and exhaust process inside the pressure regulating valve is more flexible, the steam distribution is more convenient, and the stability of the whole steam distribution mechanism is also guaranteed. In addition, the pressure regulating mechanism and the steam inlet filter are set to avoid External dust enters the pressure regulating valve and causes jamming of various parts, avoiding affecting the use, and avoiding certain hidden dangers caused by excessive air pressure inside the regulating valve. The entire steam distribution mechanism is safer and more stable. The steam process is more flexible.

Description

technical field [0001] The invention relates to a steam distribution mechanism, in particular to a steam turbine inlet steam regulating valve steam distribution mechanism with safety, belonging to the technical field of steam turbine equipment. Background technique [0002] The steam inlet regulating valve of the steam turbine is used to adjust the air intake of the steam turbine. The steam inlet and exhaust process of the steam distribution mechanism used by the existing steam inlet regulating valve is relatively slow, and the activities between the parts are not flexible and the stability is not high. At the same time The air pressure inside the valve body cannot be adjusted at any time, so there are certain hidden dangers, and once the dust enters the valve body, it is easy to cause the parts to jam, and the safety is not high. Contents of the invention [0003] The purpose of the present invention is to provide a steam turbine inlet steam regulating valve steam distrib...
