1、閥座采用與閥體整體硫化,一體性好,便于現(xiàn)場維修,并采用全流量設(shè)計(jì),不受雜質(zhì)卡阻影響,兩端的聯(lián)體環(huán)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(jù)不同使用要求選用不同材質(zhì)。
2、結(jié)構(gòu)簡單,開啟迅速。蝶板材料采用流線型設(shè)計(jì),可雙向使用,流阻小,流量特性優(yōu)異。
3、壽命長,啟閉次數(shù)多。
4、雙向密封,試驗(yàn)泄漏為零。
5、流量特性趨于直線,調(diào)節(jié)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 material adopts streamline design, which can be used in two directions, with small flow 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.
