Multi-hole sleeve labyrinth type regulating valve

Abstract

The invention discloses a multi-hole sleeve labyrinth type regulating valve which comprises a through pipe. A rotating rod penetrates through the lower part of the through pipe, a push disc is fixedly connected to the side face of the rotating rod, a limiting rod is attached to the top of the push disc, a lifting column is fixedly connected to the top of the limiting rod, a connecting ring is fixedly connected to the position, located on the inner wall of the through pipe, of the lower part of the lifting column, a connecting plate is fixedly connected to one end of the through pipe, a hydraulic rod is installed at the top of the connecting plate, a push block is installed at the output end of the hydraulic rod, a transmission block is fixedly connected to one end of the push block, and a stress rod is attached to the side face of the transmission block. Through the arrangement of the lifting column, when the rotating rod is rotated, the rotating rod can drive the push disc to rotate; due to the eccentric design of the push disc, when the push disc rotates, the lifting column can be jacked up through the limiting rod; and due to the shape arrangement of the lifting column, when the distance between the lifting column and the connecting ring is larger, the flowing speed of liquid is larger, so that the purpose of adjusting the flowing speed is achieved.

Description

technical field [0001] The invention relates to the field of regulating valves, in particular to a labyrinth regulating valve with a porous sleeve. Background technique [0002] Control valve, also known as control valve, in the field of industrial automation process control, by receiving the control signal output by the adjustment control unit, with the help of power operation to change the final control element of process parameters such as medium flow, pressure, temperature, liquid level, etc., the control valve is suitable for In air, water, steam, various corrosive media, mud, oil and other media. [0003] Many of the current regulating valves are designed with multi-hole sleeves, but in the face of the design of porous sleeves, the adjustment mechanisms of many regulating valves cannot adjust each valve well. Therefore, we propose a multi-hole sleeve labyrinth regulator valve. Contents of the invention [0004] The purpose of the present invention is to provide a l...
