進口LIPGTRBN氣動隔膜閥常閉式氣動襯氟隔膜閥的開啟是由壓縮空氣推動薄膜耐壓縮彈簧，使閥桿作軸向運動帶動閥瓣升高而達到開啟，當中斷氣源時，由于彈簧的預緊力作用而使閥門處于常閉的位置。閥門配有手操作部件，當氣源發(fā)生故障而中斷時，且閥門急需開啟的緊急狀況時，可逆時針旋轉(zhuǎn)手輪使閥門開啟。
LIPGTRBNnormally closed pneumatic lined diaphragm opening is driven by compressed air film resistance to compression of the spring, so that axial movement of the stem valve driven by increased achieve open, which expire source, due to the action of the spring preload leaving the valve is in a normally closed position. When equipped with a hand operated valve parts, when the air supply is interrupted when a fault occurs, and valves needed to open an emergency situation, you can make the counter-clockwise rotation of the hand wheel valve open.
