對夾蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°-90°之間，旋轉(zhuǎn)到90°時，閥門則牌全開狀態(tài)。此閥一般水平安裝。對夾式蝶閥結(jié)構(gòu)簡單、體積小、重量輕，只由少數(shù)幾個零件組成。而且只需旋轉(zhuǎn)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。蝶閥處于完全開啟位置時，蝶板厚度是介質(zhì)流經(jīng)閥體時唯一的阻力，因此通過該閥門所產(chǎn)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 setupthat clips die valve.at inside the gateway, the die valve valvebody cylinder shape"s the disc shape die board rounds shaft wirerevolution, revolve the angle as of 0 °-90 °, while revolving to 90° card full opening status in valve portal.the this valve generalhorizontal installs.vs the clip type die valve the structure issimple, small volume, the weight is light, constitutes to°fromminority of a few kits.and needs to revolve 90 ° then rapid qi toshut, the operation is simple, the valve"s portal has good fluidcontrol characteristic at the same time.when die valve was placedin to completely open location, the die board thickness was theonly resistance for dielectric to flows through valve body,therefore cutting through the press that the valve"s portalgenerates is very small, so have better flow controlcharacteristic.the die valve has already played hermetic sealingand metallic to seal completely two kinds of hermetic sealingpatterns.the elasticity seals completely a valve portal, thehermetic sealing ring can inset on the valve body or attachperipheral at the die board.

廣泛用于：化工、石化、冶煉、醫(yī)藥、食品等行業(yè)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(zhì)的管路上作為調(diào)節(jié)和截流裝置使用。

extensively used for:chemical engineering, petrochemical, theso2, steam, air, gas and ammonia in smelting, medicine, provisionsetc. 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 thatconditioning and piece flow a device use.
