lt型單夾中線蝶閥 lugged typeconcentricbutterflyvalve
產(chǎn)品特點：
本蝶閥主要由閥體、轉軸、閥板、閥座及驅動機構（手柄、蝸輪蝸桿、氣動裝置或電動裝置）等組成，靠驅動機構帶動轉軸及閥板旋轉以實現(xiàn)啟閉和控制流量的目的。其特點如下：
結構簡單、小巧輕便，運輸、安裝、拆卸容易;90°啟閉，開關迅速。操作扭矩小，省力輕巧;密封性能好，使用壽命長，可達到零泄漏;選擇不同的零部件材質，可適用于多種介質;流量特性近似于直線，調節(jié)性能好。
a butterfly valve consists of body ,stem ,disc , actuator (manualactuator, worm-gear actuator , aerodynamic actuator or electricactuator) , and it can implement the process for turning on turningoff and regulating the flow by the circumrotation of stem and discthat is droved by actuators.
1.simple and compact construction. small in size and light inweight. 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 servicelife.
4. wide selection of materials ,applicable for various media..
5. flow curve tending to straight line. excellent regulationperformance.
