High-end manufactured drain valve for water conservancy project

Abstract

The invention relates to the technical field of a water conservancy project, and provides a high-end manufactured drainage valve for the water conservancy project. The drainage valve comprises propellers, wherein a pipeline is movably connected to the outer walls of the propellers, sliding balls are movably connected to the outer wall of the pipeline, springs are movably and elastically connectedto the outer walls of the sliding balls, and sliding rails are movably connected to the outer walls of the springs. According to the high-end manufactured drain valve for the water conservancy project, water flow drives the propellers to rotate, the propellers rotate to enable the water flow to advance rotationally, a centrifugal force of rotating water extrudes the sliding balls, the sliding balls push the sliding blocks to move, the pushing distance of the sliding blocks is related to the speed of the water flow, stand columns move on the outer walls of clamping grooves under the joint action of a pentagonal rail and a wheel disc, the size of an opening is changed by baffles, when the flow speed of water is too high, the opening formed by the baffles is maximum, the flow speed of water is reduced, the drain valve is prevented from being damaged due to the too high flow speed of water, and when the flow speed of water is too low, sludge accumulation is prevented, and the opening sizeof the drain valve is dynamically adjusted through the flow speed of water.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a high-end manufactured drain valve for water conservancy engineering. Background technique [0002] Drain valve is an essential water industry product, mainly used in cities, buildings, enterprise water supply and drainage projects, industrial and domestic sewage treatment and water conservancy projects, mainly used for liquid discharge or liquid level control, with the times With the development of water conservancy projects, water conservancy projects continue to cover rivers. Drainage valves are used to control the flow rate and hydraulic pressure of water. Drainage valves play an important role in water conservancy projects. [0003] In the prior art, the water flow rate through the drain valve usually requires manual operation to adjust the water flow rate, and the water flow rate is different every moment, and the water is irregular, and people cannot...

Problems solved by technology

[0003] In the prior art, the water flow rate through the drain valve usually requires manual operation to adjust the water flow rate, and the water flow rate is different every moment, and the water is irregular, and people cannot adjust it at any time according to the water flow rate at any time, and The inner wall of the drain valve is easily covered with sludge after long-term use. The thicker the sludge will block the drain valve and seriously affect the damage of the machine, so a high-end drain valve for water conservancy projects came into being.
