对夹蝶阀的蝶板安装于管道的直径方向。在蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为0°-90°之间，旋转到90°时，阀门则牌全开状态。此阀一般水平安装。对夹式蝶阀结构简单、体积小、重量轻，只由少数几个零件组成。而且只需旋转90°即可快速启闭，操作简单，同时该阀门具有良好的流体控制特性。蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体时唯一的阻力，因此通过该阀门所产生的压力降很小，故具有较好的流量控制特性。蝶阀有弹密封和金属的密封两种密封型式。弹性密封阀门，密封圈可以镶嵌在阀体上或附在蝶板周边。

It is at the diameter direction of piping to the Die bOArd setup that clips Die valve.At inside the gateway, the Die valve valve body cylinder shape's the disc shape Die board rounds shaft wire revolution, revolve the angle as of 0 °-90 °, while revolving to 90 ° card full opening status in valve portal.The this valve general horizontal installs.Vs the clip type Die valve the structure is simple, small volume, the weight is light, constitutes to°from minority of a few kits.And needs to revolve 90 ° then rapid Qi to shut, the operation is simple, the valve's portal has good fluid control characteristic at the same time.When Die valve was placed in to completely open location, the Die board thickness was the only resistance for dielectric to flows through valve body, therefore cutting through the press that the valve's portal generates is very small, so have better flow control characteristic.The Die valve has already played hermetic sealing and metallic to seal completely two kinds of hermetic sealing patterns.The elasticity seals completely a valve portal, the hermetic sealing ring can inset on the valve body or attach peripheral at the Die board.

      广泛用于：化工、石化、冶炼、医药、食品等行业中SO2、蒸汽、空气、煤气、氨气、CO2气、油品、水、盐水、碱液、海水、硝酸、盐酸、硫酸、磷酸等介质的管路上作为调节和截流装置使用。

      Extensively used for:Chemical engineering, petrochemical, the SO2, steam, AIr, gas and ammonia in smelting, medicine, provisions etc. craft gas, CO2 gas, the piping of the oil article, water, brine, alkali liquid, sea water, nitric acid, hydrochloric acid, sulfuric acid, the phosphoric acid etc. dielectric up are that conditioning and piece flow a device use.
