產(chǎn)品特點：
     對夾中線蝶閥主要由閥體、轉(zhuǎn)軸、閥板、閥座及驅(qū)動機(jī)構(gòu)（手柄、蝸輪蝸桿、氣動裝置或電動裝置）等組成，靠驅(qū)動機(jī)構(gòu)帶動轉(zhuǎn)軸及閥板旋轉(zhuǎn)以實現(xiàn)啟閉和控制流量的目的。對夾式蝶閥特點如下：
     結(jié)構(gòu)簡單、小巧輕便，運輸、安裝、拆卸容易;90°啟閉，開關(guān)迅速。操作扭矩小，省力輕巧;密封性能好，使用壽命長，可達(dá)到零泄漏;選擇不同的零部件材質(zhì)，可適用于多種介質(zhì);流量特性近似于直線，調(diào)節(jié)性能好。
      Abutterfly valveconsists of body ,stem ,disc , actuator （manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator） , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
1.Simple and compact construction. Small in size and light in weight. Easy transportation , installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with no leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.
