Flow regulating valve for hydraulic engineering

Abstract

The invention discloses a flow regulating valve for hydraulic engineering. The flow regulating valve comprises a bottom cover, a valve body, a shut-off assembly and a flow regulating assembly; the bottom cover is rectangular frame-shaped; the valve body is arranged in the bottom cover; connecting flanges are coaxially connected at two ports of the valve body; the shut-off assembly is connected toone end of the valve body; a first runner pipe contained in the shut-off assembly communicates with the valve body; a sealing block is arranged in the first runner pipe; the sealing block is connectedwith a first moving mechanism at the upper end of the first runner pipe; the flow regulating assembly is connected to the other end of the valve body; a second runner pipe contained in the flow regulating assembly communicate with the valve body; a plurality of flow regulating blocks are distributed in the second runner pipe, and the apertures of circular holes in the middle parts of the flow regulating blocks from top to bottom are increased in sequence; the first runner pipe communicate with the second runner pipe through a connecting pipe; a rotating motor is arranged on the bottom cover;a circular valve body is movably arranged in the middle part of the valve body; and the circular valve body is connected with the rotating motor. A waterway can be quickly shut off, the flow can be adjusted, and the use is efficient and quick.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a flow regulating valve for water conservancy engineering. Background technique [0002] Valves are used in fluid control systems, ranging from the simplest globe valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard custom valves and other valve materials according to the material. [0003] At present, valves are widely used in water conservancy projects, especially in agricultural water conservancy...

AI Technical Summary

Problems solved by technology

[0003] At present, valves are widely used in water conservancy projects, especially in agricultural water conservancy projects; however, the valves used in existing water pumps respond slowly when opening and closing, which cannot meet the requirements of on-site use, especially in special cases where waterways need to be cut off quickly. In addition, it is inconvenient to adjust the flow of the existing valve, so it is particularly important to design a valve that can quickly shut off the waterway and adjust the flow.
