L型電動三通球閥產品概述

L型電動三通球閥是由DSR角行程電動執行器及三通球閥組成，是一種旋轉類切斷、調節閥門，具有關閉嚴密，結構緊湊，重量輕，維修方便等優點。以220V單相交流電為動力源，接受控制系統的開關信號，通過單相電源切換驅動可逆單相齒輪減速機，使球閥按規定要求對管路進行切換。兩閥座密封具有結構緊湊、外型美觀、密封性能好，它能實現對管道中介質流向的切換，也能使相互垂直的兩個通道連通或關閉。四閥座密封具有造型美觀、結構緊湊合理。它不僅可實現介質流向的切換，也可使三個通道相互連通，現時也可關閉任一通道，使另外兩個通道連通，靈活控制管路中介質的合流或分流。電動三通球閥適用于供水、石化、冶金、礦山、輕紡、能源、造紙、食品、鋼鐵等管路系統中對介質流向進行切換以及對介質的分流或混合流體。

主要特點

1、結構緊湊、啟閉迅速、流道暢通、流體阻力小。
2、密封性能好：利用四面閥座材料聚四氟乙烯彈性變形實現無泄漏密封。
3、一閥多用：任一通口可用作入口而無泄漏，三通既可制成L型通口，也可制成T型通口。
4、維修方便：在系統卸壓后，無需拆下整個閥體就可進行檢查和維修。

執行機構

注：如需詳細執行器參數，請進入電動執行器頁面進行查閱。

控制方式

分L型和T型，介質流通方向見下圖。適用于介質流向的切換，能使相互垂直的兩個通道連通：T型適用于介質的分流、合流或流向 切換，T型孔道可以使三個通道互相連通或使其中兩個通道連通，電動三通球閥一般采用兩個閥座結構，亦可根據用戶要求采用四閥座結構。
