进口双偏心半球阀—英国ARI阿里斯顿，利用偏心阀体，偏心球体和阀座，阀杆作旋转运动时在共同轨迹自动定心，关闭过程中越关越紧，完全达到良好的密封目的。阀门的球体和阀座完全脱离，消除了密封圈的磨损，克服了传统球体阀座与球体密封面始终磨损的问题，非金属弹性材料被嵌入金属座中，阀座金属面受到良好的保护。本产品特别适用于钢铁业，铝业，纤维，微小固体颗粒，纸浆，煤灰，石油气等介质结构特点 Structural characteristics
1、电动阀座设外台阶与阀体内台阶相配合的结构，防止了球体与阀座发生卡阻或脱离现象。
2、利用偏心阀体、偏心球体和阀座、阀杆作旋转运动时，在共同轨迹自动定心，关闭过程中越关越紧，完全达到良好密封的目的，所以偏心半球阀密封性能安全可靠；阀门启闭时，球体与阀座完全脱开。消除了密封副的磨损，克服了传统球阀阀座与球体密封面始终磨损的问题。
3、非金属弹性材料被嵌于金属座中，阀座金属密封面收到良好的保护。
4、全开时流通能力大、压力损失小，且介质不会沉积在阀体中内。
5、使用寿命长，密封副耐磨，且有补偿量，阀座可调整或更换。
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, completely 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 completely 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 completely, 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.
工作原理The principle of work
执行器（或扳手）带动阀杆迫使关闭件球体绕中心A转动，球体自B点移至C点，此时相对阀门中心点0，从B到C的轨迹为一凸轮状偏心，右旋进入阀座是阀门关闭保持优良密封，该产品按凸轮原理设计，阀门关闭件从开启到关闭过程中，作用在阀座上的力逐渐增加，即关闭件表面与阀座由完全脱离至接触，并逐渐增大密封比压，直至完全密封，反之为开。见下图：
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 completely from to the contact, and gradually increases the pressure to seal, until completely seals, otherwise for opens.
