手动铸钢蝶阀

我公司”蝶一”拥有多年生产经验蝶阀的历史并有部分产品申请获得了专利，在不断吸引外资技术和运用的基础上获得了市政和用户的青睐。

蝶阀是用圆形蝶板作启闭件并随阀杆转动来开启、关闭和调节流体通道的一种阀门。蝶阀不仅结构简单、体积小、重量轻、材料耗用省，安装尺寸小，而且驱动力矩小，操作简便、迅速，并且还同时具有良好的流量调节功能和关闭密封特性，在大中口径、中低压力的使用领域，蝶阀是主导的阀门形式。随着防腐合成橡胶和聚四氟乙烯的应用，蝶阀的性能得以提高，并满足于不同的工况条件。近十几年来，金属密封蝶阀发展迅速，随着耐高温、耐低温、耐强腐蚀、耐强冲蚀、高强度合金材料在蝶阀中的应用，使金属密封蝶阀在高温、低温、强冲蚀等工况条件下得到广泛的应用，并部分取代了截止阀、闸阀和球阀。 结构特点：蝶阀具有结构简单、体积小、重量轻、材料耗用省，安装尺寸小，开关迅速、90°往复回转，驱动力矩小等特点，用于截断、接通、调节管路中的介质，具有良好的流体控制特性和关闭密封性能。 公称压力或压力级：PN1.0-4.0MPa、ANSI CLASS 150-300LB、JIS10-20K 公称通径或口径：DN40～2000 连接方式：法兰连接、对夹连接、对焊连接及凸耳对夹连接适用温度：-196℃～700℃ 驱动方式：手动、蜗轮传动、气动、电动、液动、气液联动、电液联动阀体材料：HT200、WCB、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、CF8(304)、CF3(304L)、CF8M(316)、CF3M(316L)。
