產品結構特點 Construction features
本產品主體為球閥與蝶閥的結合,主要結構類似蝶閥,而閥芯為部分球體即閥芯取球體實際有效的一部分即密封面附近的一部分,閥座為串動環體,閥芯轉動中心與球體中心不同心。剖面圖上可見球體的弧面與環錐面接觸的點與球中心形成的垂足都不與環錐面剖線垂直,換言之,閥座密封面不是球體的切線形成的連續面。有反向作用壓力或反向作用壓力大于正向作用壓力時形成反壓差,閥座串動自動補償密封間隙,使之達到雙向密封。作用壓力越大,雙向密封的效果越好。
This product is subject to the combination of ball valve and butterfly valve, the main structure similar to butterfly valve, the valve core for part of the sphere
which take ball valve core part of the real effective near the sealing surface, as part of the seat for the ring body, valve core center of rotation is different from a sphere center. Profile is visible on the sphere surface contact with ring cone with the pedal is not formed by the center points and the ball ring cone vertical profile, in other words, the valve seat sealing surface is not a sphere A continuous surface of a line. With reverse pressure or reverse the role against the differential pressure is greater than the positive effect when, seating series of dynamic self-compensation seal clearance, to two-way sealing. The more pressure, the better the effect of the bidirectional seal.
