一、 安装前准备工作： １、安装前应核对膈膜阀之规格、材料是否与设计相符合。 ２、 并于安装前将内部之砂尘、异物及杂屑清理干净， 　　以免造成动作不顺或产生泄漏。 ３、 安装前其相关之配管应按规作适当之悬吊固定， 　　以避免安装后对阀产生不当之应力。 ４、 配管之两法兰面间必须平行对准同心。 ５、 安装时膈膜阀与法兰间需另行加装垫片。 二、 安装步骤： １、 安装前将内部之砂尘、异物及杂屑清理干净。 ２、 在适当位置设定辅助螺丝，以调整两法兰面距离。 ３、 将膈膜阀以不接触两法兰面插入同时穿入其余螺栓。 ４、 于确定膈膜阀中心与法兰中心同心且以对角渐进方 　　式反复锁紧各螺栓，直到法兰面接触到阀体端面。 三、 操作： １、 开始操作前，用空气喷洗xx配管上的外物，配管内面用清水清洗干净。 ２、 打开阀查看角度指示盘，避免扭转超过开启宽度、关闭位置也不可超过。 ３、 开关之操作xx以指示器为准，如再加以其它手工具施力时，则角度指 　　示盘及开关器将会损坏。 ４、 要做配管耐压试验时，应将阀打开。 ５、 配管后凡而长期处于全关状态，每月应做1~2次的开关动作以免产生固着状况。

First, install the pre-work: 1, diaphragm valves before installation should check specifications, materials and design is consistent. 2, and in the sand and dust prior to installation of internal, foreign bodies and miscellaneous debris clean up Action will not ring true or produce so as to avoid leakage. 3, pre-installation of its associated piping should be regulation to make appropriate suspension fixed, In order to avoid improper installation of the valves of the stress generated. 4, the piping between the two flange surfaces must be aligned parallel to concentric. 5, installed between the diaphragm valve and flange gasket must be installed. 2, the installation steps: 1, the installation of sand and dust before the internal, foreign bodies and miscellaneous debris clean up. 2, in the appropriate place to set auxiliary screw to adjust the distance of two flange surfaces. 3, the diaphragm valve to no contact with two flange bolts inserted at the same time penetration of the rest. 4, to determine diaphragm valve center and concentric flange center to right corner and the progressive side Type repeatedly locking the bolt, until access to the valve flange face. 3, the operation: 1, before commencing operation, and using air spray washing on the removal of foreign objects piping, piping cleaned with water inside. 2, open the valve view angles instruction set, to avoid the reversal of more than open the width of the closed position must not exceed. 3, the switch of the operation entirely subject indicator, such as the addition to dictate other hand tools, then the angle that Show disk and switching devices will be damaged. 4, done piping pressure test, valve should be opened. 5, where the piping after long-term in a fully closed state, a month should be done 1 or 2 times the switching action in order to avoid fixing the situation.
