Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples.

As shown in fig. 1-3, an embodiment of the present invention is a gas turbine bleeding valve capable of being started by one key, including a housing 1, an end cap 2, a valve core 3, a rotating shaft 4, a bearing 5, and a motor 6, where the outer side of the housing 1 is provided with the end cap 2, the valve core 3 is installed in the housing 1, the rotating shaft 4 is fixed by the bearing 5, the rotating shaft 4 is coaxially connected to the valve core 3, one end of the rotating shaft 4 is connected to an output end of the motor 6, the housing 1 is provided with three open ends, which are an inlet end 7, an outlet end 8, and a bleeding end 9, the valve core 3 is provided with three openings 10, the motor 6 drives the valve core 3 to rotate in the housing 1 through the rotating shaft 4, so that the gas turbine bleeding valve is in a normal state and a bleeding state, and in the normal state, the two openings of the valve core 3 are respectively communicated with the inlet end 7 and the outlet end 8 of the housing 1, the other opening is closed by the inner wall of the shell 1, in a diffusion state, two openings 10 of the valve core 3 are respectively communicated with the inlet end 8 and the diffusion end 9 of the shell 1, the other opening is closed by the inner wall of the shell 1, the motor 6 is supported by a motor mounting seat 11, the motor mounting seat 10 is mounted on the end cover 2, the number of the bearings 5 is two, so that the rotating shaft 4 is stably mounted, and the bearings 5 are mounted on the shell 1.

During specific implementation, the valve is connected with a pipeline through a flange, the valve core 3 can rotate around the rotating shaft 4 in the forward direction and the reverse direction by 90 degrees, and the shell 1 and the valve core 3 are sealed through a clearance fit surface.
