進口偏心半球閥
德國泰科閥門()有限公司—廣州總代理
德國泰科雙偏心半球閥利用偏心閥體,偏心球體和閥座,閥桿作旋轉運動時在共同軌跡自動定心,關閉過程中越關越緊,*達到良好的密封目的。
閥門的球體和閥座*脫離,消除了密封圈的磨損,克服了傳統球體閥座與球體密封面始終磨損的問題,非金屬彈性材料被嵌入金屬座中,閥座金屬面受到良好的保護。
本產品特別適用于鋼鐵業,鋁業,纖維,微小固體顆粒,紙漿,煤灰,石油氣等介質
德國泰科雙偏心半球閥結構特點:
1、電動閥座設外臺階與閥體內臺階相配合的結構,防止了球體與閥座發生卡阻或脫離現象。
2、利用偏心閥體、偏心球體和閥座、閥桿作旋轉運動時,在共同軌跡自動定心,關閉過程中越關越緊,*達到良好密封的目的,所以偏心半球閥密封性能安全可靠;閥門啟閉時,球體與閥座*脫開。消除了密封副的磨損,克服了傳統球閥閥座與球體密封面始終磨損的問題。
3、非金屬彈性材料被嵌于金屬座中,閥座金屬密封面收到良好的保護。
4、全開時流通能力大、壓力損失小,且介質不會沉積在閥體中內。
5、使用壽命長,密封副耐磨,且有補償量,閥座可調整或更換。
1、The valve’s seat have a step which out of valve and coordinate with inner steps, then had prevented the spheroid and the valve seat has the card anti-or is separated from and so on the phenomenon.
2、To use valve body of an eccentric, the spheroid of an eccentric and the valve seat, then the valve lever make the rotary motion, in common path self-centering, closure process tighter and tighter, compley achieves the good seal, therefore the hemisphere of an eccentric valve seal performance safe; when the valve opens or shuts, the spheroid and the valve seat compley withdraw, Eliminated ha sealed the attrition of side effect, ha overcome problem of the traditional ball valve and valve seat and the spheroid packing surface of wore.
3、material of elastic in the nonmetallic is inlaid in the metal place, the valve seat metal packing surface attains good protection.
4、when all opens, the circulates compley, and the pressure slightly loses, also the medium cannot deposit in the valve body.
5、Long-life sealed vice wear, and the compensation amount, or the replacement of an adjustable valve seat.
德國泰科雙偏心半球閥工作原理The principle of work
執行器(或扳手)帶動閥桿迫使關閉件球體繞中心A轉動,球體自B點移至C點,此時相對閥門中心點0,從B到C的軌跡為一凸輪狀偏心,右旋進入閥座是閥門關閉保持優良密封,該產品按凸輪原理設計,閥門關閉件從開啟到關閉過程中,作用在閥座上的力逐漸增加,即關閉件表面與閥座由*脫離至接觸,并逐漸增大密封比壓,直至*密封,反之為開。見下圖:
Performer(or spanner) drives the valve force spheroid to the shutting down to circle the rotation with central A, when the spheroid from B moves to C, this time the relative central point o, from B to the C path is a cam shape bias, and dextrorotation to enters the valve seat to make the valve closure to maintain the fine seal, this product design according to principle of cam, the valve in process from opens to the closure, affects the strength gradually increases on the valve seat, namely the shutting down surface and the valve seat are separated compley from to the contact, and gradually increases the pressure to seal, until compley seals, otherwise for opens.
