进口隔膜阀说明书/气动隔膜阀说明书
进口隔膜阀启闭件是一块用软质材料制成的隔膜，把阀体内腔与阀盖内腔及驱动部件隔开，故称气动隔膜阀。气动隔膜阀式指由气动执行器和隔膜阀组成，有气动执行器控制隔膜阀自动开启和关闭的隔膜阀

2.气动阀门均有手操部件，当气源发生故障而中断时，且阀门急需启、闭的紧急状态下，可顺时针旋转手轮使阀门关闭，反之则开启。
Pneumatic valves are the terminal parts, when the gas supply is interrupted failure, and valves need opened, closed under the state of emergency, clockwise handwheel valve closes, conversely open.
3．当需恢复气动操作时，必须首先旋转手轮至气缸内留有最大行程间隙后，方可输入操作气源。
When to recover pneumatic operation, must first rotation handwheel to leave in the air gap and then travel after maximum input operating air supply

Switch on the power.
Replace indicator light,
Debug correction or replacement.
Adjusted gears circle position.
Ⅳ. 维护保养和安装使用注意事项
Maintenance and installation using precautions
本阀必须放在干燥通风的室内，温度宜在0°C~35°C之间；相对湿度为50~80%之间，以防衬里件老化而影响使用寿命。
The valve must be placed in dry and ventilated room, the temperature should be at 0 ° C ~ 35 ° C between; relative humidity of 50 to 80%, and prevent aging of lining pieces of life.
应避免与液体燃料、油料或其它易燃物品接触。
Should be avoided with liquid fuel, oil or other flammable materials contact.
在存放期间或使用期间,应逆时针旋转手轮,使阀门处于微启状态,避免使隔膜因长期受压而失去弹性.
During storage or use during the hand wheel should rotate counter-clockwise, so that the valve is inching state, to avoid the divide and lose their elasticity due to prolonged pressure
安装前,应仔细核对管路使用条件是否与本阀规定的适用范围相符;避免因选用不当而造成不必要的损失。
Before installation, check carefully whether the conditions of pipe to use the provisions of this scope in line valve; to avoid the improper selection of unnecessary losses
安装过程中，应将阀体内腔清洗干净,避免污垢卡阻或损伤密封部件;并检查连接部位的连接螺栓是否均匀紧固。
The installation process, you should wash the body cavity to prevent dirt jamming or damage the sealing components; and check the connection parts of the connection bolts are evenly tightened.
运行中必须经常检查与介质接触的密封部位及其它易损零件;并按实际使用情况，定期更换易损部件。
Operation, you must always check the seal area contact with the media and other vulnerable parts; according to actual usage, regular replacement of wearing parts
当需要更换管夹时,应注意切勿将隔膜拧得过紧或过松。
When the need to replace tube clip，Diaphragm should not be too tight or too loose screw
在检修中，当必须打开气缸与气缸盖时，应首先排除气缸内的气源压力，然后方可拆除连接螺栓。
In the repair, when to open the cylinder and cylinder head, they should first rule out the air pressure inside the cylinder, then remove bolts
本阀如用于间断性运行的管路上，则在停止使用时，应清洗与介质接触部位，以延长阀门使用寿命。
If the valve for the intermittent operation of the pipeline, when not in use, the contact area should be cleaned with the medium to longer valve life
在手动操作阀门时，不得借助于辅助杠杆使阀门启闭，以免扭矩过大而损伤驱动零件或密封部位。
In the manual operation of the valve may not open and close the valve by means of auxiliary lever so as to avoid excessive torque while the injury-driven part or sealing parts
14．凡经检修后的阀门，应按有关规定进行密封性能试验，合格后方能安装使用，并作好记录以供查考。
After all, after the valve repair, according to relevant provisions of the sealing performance test, qualified before installation and make records for the traced
