產品結構特點 Construction features
1、閥座采用與閥體整體硫化,一體性好,便于現場維修,并采用全流量設計,不受雜質卡阻影響,兩端的聯體環型密封線使管道安裝無須附加墊片而保持可靠密封,并可根據不同使用要求選用不同材質。
2、結構簡單,開啟迅速。蝶板材料采用流線型設計,可雙向使用,流阻小,流量特性優異。
3、壽命長,啟閉次數多。
4、雙向密封,試驗泄漏為零。
5、流量特性趨于直線,調節性能好。
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.
