产品结构特点 Construction features

1、阀座采用与阀体整体硫化，一体性好，便于现场维修，并采用全流量设计，不受杂质卡阻影响，两端的联体环型密封线使管道安装无须附加垫片而保持可靠密封，并可根据不同使用要求选用不同材质。
 2、结构简单，开启迅速。蝶板材料采用流线型设计，可双向使用，流阻小，流量特性优异。
 3、寿命长，启闭次数多。
 4、双向密封，试验泄漏为零。
 5、流量特性趋于直线，调节性能好。
 1. The overall seat with body sulfide, oneness is good, is advantageous for the on-site maintenance, and adopts the design of full flow is not affected by impurities jam, conjoined at the ends of the ring seal line keep pipe installation without additional gaskets, reliable sealing, and can choose different materials according to the different use requirement.
 2. Simple structure and quick opening. The butterfly plate is designed with streamlined design, which can be used in both directions, low resistance and excellent flow characteristics.
 3. Long life, more open and close.
 4. Bidirectional seal, test leakage is zero.
5. Flow characteristics tending to a straight line, adjusting the performance well.
