              結構特點及用途Structural features and purposes

                本系列閥門除具有普通球閥流阻小、啟閉迅速、密封性能好等優點外,還具以下特點:
                1、本閥采用偏心結構,閥門在關閉過程中,閥座與球體間的密封比壓迅速增加,從而確保了密封副的可靠密封。當閥門開啟時,閥座與球體迅速脫離,有效的減小了操作力矩,并使閥座表面與球冠球面間的擦傷可能性降到低。
                2、壓力損失小,全開時損失為零,流道完全暢通,且介質不會沉積在閥體中腔內。
                3、使用壽命長,閥門無易損部件,由于偏心的作用,閥門啟閉時無摩擦,使閥門的壽命大大延長。
                4、維修方便,球冠和支承體從閥門上部裝入,檢修時只需打開閥蓋吊出球冠和支承體而不必將整個閥門從管道上卸下來,這給地下管線,特別是原子能工業用球闖帶來很大方便。
                5、本系列閥門體積小,重量輕,具有雙向止水功能,廣泛適用于水、蒸汽、煤氣、天然氣、油品及含微小國體顆粒等場合
                In addition to the features with the common ball valve of small fluid resistance,quick open-close and good tightness,this series valve also holds those below:
                1、This valve uses an eccentric structure During the valve close,the specific pressure of the seal between both seat ring and ball is fast increased,thus making sure of reliable sealing of the seal pair and,when the valve is opened,both seat ring and ball are quick separated,thus effectively reducing the operation torque and making the possibility of the scrapping damage between the seat ring surface and the spherical crown surface to the minimum.
                2、Small pressure loss,to be zero at full-open Completely unblocked runner and the medium will not be deposited in the mid-cavity of the aody.
                3、Long duration No easily wearable parts with the valve and,because of the eccentric action,no friction at open-close,making the valve long endurable.
                4、Convenient repair Both spherical crown and support body are mounted in from the top of the valve and,at repair,iust open the valve cover to take the both while no need to have the whole valve removed from the pipeline This b rings a great convenience to the underground pipeline especially for the ball valve used for the atomic energy industry.
                5、Small volume and light weight,of the function to stop water in dual-ways,applicable for water,steam,coal gas,natural gas,oil goods and the medium containing micro solid grains.
