Description

Technical Field

[0002] The multi-stage throttling electric control valve is a valve that uses a multi-stage throttling structure to achieve high-pressure differential fluid control. This valve is generally suitable for boiler water supply systems in thermal power plants, petrochemical industries, and other industrial fields. It can maintain good sealing and stable flow regulation performance under large pressure differentials. The valve components of the electric control valve include a sleeve and a valve core. They adopt a mixed structure of multi-holes and cascades, so that the fluid first passes through the sleeve window for the first stage of throttling, and then undergoes continuous cascade throttling to achieve effective flow control and pressure balance.

The top of the connecting member 411 is contacted with a connecting plate 412. The side wall of the connecting plate 412 is fixedly mounted with a side plate 414. The bottom of the side plate 414 is fixedly mounted with a plug-in block 415. The side wall of the connecting plate 412 is fixedly mounted with a limit plate 413. The side wall of the limit plate 413 is rotatably mounted with a rotating plate 4112. The inner wall of the rotating plate 4112 is connected to the connecting plate 412 through a bearing. The side wall is rotatably connected, and an adjusting rod 416 is fixedly installed on the bottom of the rotating plate 4112, and an arc rod 417 is fixedly installed on the side wall of the adjusting rod 416. A rectangular plate 418 is fixedly installed on the top of the connecting plate 412, and a column 4110 is slidably installed on the inner wall of the rectangular plate 418. A pull block 419 is fixedly installed on the top of the column 4110, and a compression spring 4111 is fixedly installed on the bottom of the pull block 419. The bottom of the compression spring 4111 is fixedly connected to the top of the rectangular plate 418.

[0031] In this embodiment, the side wall diameter of the column 4110 is the same as the inner wall diameter of the circular hole opened on the surface of the rotating plate 4112. The side wall of the column 4110 is slidingly connected to the inner wall of the circular hole, and the column 4110 can be inserted into the inner wall of the rotating plate 4112.

[0032] Furthermore, the side wall diameter of the arc rod 417 is the same as the inner wall diameter of the circular groove opened on the side wall of the plug-in block 415, and the side wall of the arc rod 417 is slidably connected to the inner wall of the circular groove.
