對夾蝶閥的蝶板安裝於管道的直徑方向。在蝶閥閥體圓柱形通道內，圓盤形蝶板繞著軸線旋轉，旋轉角度為0°-90°之間，旋轉到90°時，閥門則牌全開狀態。此閥一般水平安裝。對夾式蝶閥結構簡單、體積小、重量輕，隻由少數幾個零件組成。而且隻需旋轉90°即可快速啟閉，操作簡單，同時該閥門具有良好的流體控制特性。蝶閥處於完全開啟位置時，蝶板厚度是介質流經閥體時唯一的阻力，因此通過該閥門所產生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。

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.

      廣泛用於：化工、石化、冶煉、醫藥、食品等行業中SO2、蒸汽、空氣、煤氣、氨氣、CO2氣、油品、水、鹽水、堿液、海水、硝酸、鹽酸、硫酸、磷酸等介質的管路上作為調節和截流裝置使用。

      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.
