进口保温蝶阀摘要：Imported thermal insulation butterfly valve:
进口保温蝶阀也称夹套蝶阀，是在普通三偏心金属硬密封蝶阀的基础上在阀体外部焊装了金属夹套，在保温蝶阀的阀体两侧装有夹套接口，可涵入蒸汽或其它过热气体，以防止介质在常温状态下凝固或结晶。保温蝶阀的法兰较普通金属硬密封蝶阀要大一到两个规格，主要用于石油、化工、冶金、制药等各类系统。The imported insulation jacket also known as butterfly valve, is based on common three eccentricity metal hard sealing butterfly valve on the valve outside welding metal jacket in the insulation body arranged on both sides of the jacket valve interface, can cover the steam into superheated gas or other, to prevent solidification at room temperature or crystallizing media. The flange of the heat insulation butterfly valve is one to two sizes larger than the ordinary metal hard seal butterfly valve, which is mainly used in various kinds of systems, such as oil, chemical, metallurgy, pharmaceutical and so on.
进口保温蝶阀的一般使用场合：
1、软密封蝶阀适用于通风除尘管路的双向启闭及调节，冶金、轻工、电力、石油化工系统的煤气管道及水道等。
2、金属密封双偏心蝶阀适用于供热、供汽、供水及煤气、油品、酸等管路，作为调节和截流装置。
3、金属密封三偏心蝶阀除作为大型变压吸附气体分离控制阀外。
4、金属密封三偏心蝶阀可广泛用于石油、化工、冶金、电力、食品、医药、给排水、气体输送等领域。
