结构性能特点
QV型开口球阀是为满足精确调节与严格关断的要求而设计的,与一般V型球阀不同,本球阀的V型开口在阀座球上,这样,兼具V型球阀的调节性能与O型球阀的关断性能。不同型式的开口,获得不同的调节流量特性。这些阀球可以很方便地进行各种流量特性的调节。
Characters
The QV-type valve provides positive shut-off with accurate manipulation .It is different from the common V-type valve, the V-type hatch lies on the ball, thus combines the V-type ball valve manipulation and the O-type ball valve shut off ability, winning different flux characters.
