快开排泥阀


用途 Applications
快开排泥阀广泛适用于给水排水工程中的各类沉淀池,该排泥阀可采用液压、气压、油压等介质,能快速排放池底的沉淀物,大大地降低了操作人员的劳动强度。
Fast-opening mud-discharging valve is widely used in all kinds of sedmental tanks of water-supplying and-draining projects.The mud-discharging valve for which the principle of hydraulic pressure,air pressure or oil pressure can be adopted can fast discharge the sedments at the bottom of the tanks,so that it can greatly relief the intensity of work.

工作原理 Working Principle
阀门开启∶ 介质(水、气、油)通过换向阀(手动四通阀或电磁阀)进入缸体下腔,推动活塞上行,带动底止水盖板打开,此时开始排泥,随着上行的距离增大排泥量也增大。
活塞推动上行的介质通过换向阀在上行的同时排出,至此整个开启过程完成。
阀门关闭∶ 排泥彻底后,四通阀换向,介质由四通阀进入缸体上腔,推动活塞向下运行,使底止水盖板与底座密闭,达到关闭状态,排泥停止,缸体下腔的介质通过四通阀排放孔排掉,至此整个排泥过程全部完成。

Opening of valve: The media (water, gas and oil) will, through the direction-changing valve(manual 4-way valve or electro magnetic one),enter the lower chamber of cylinder to push the piston to make an upstroke and to drive the bottom water-blocking cover open,At this time the mud begins being discharged and the volume of discharged mud will graduall increaes with the enlargemont of the upstoke.
The piston is pushed upwards and the media will through the direction-changing valve,be discharged while the piston is in the course of upstroke .UP to then the whole opening course is finished.
Closing of valve:When the mud is thoroughly removed,the 4- way valve changes.The media are,throuyh 4-way valve,pressed into the upper chamber. The piston is pushed downwards,and the water cover and the base are closed tightly,then removal of mud is suspended.Water in the lower chamber is discharged throuth holes of the four-way valve and the whole removal of mud is finally over.
