Diaphragm valve maintenance and installation Diaphragm is a special form of cut-off valve, diaphragm valve opening and closing pieces is a soft material with a diaphragm, the body cavity and the valve cover cavity and drive components are separated, it said diaphragm. Diaphragm maintenance and installation notes: 1 diaphragm should be stored in dry and ventilated room, is strictly prohibited stacked placed. (2) inventory at both ends must be sealed diaphragm pathway to prevent foreign matter into the cavity and damage the seal components. And should avoid contact with oil or other flammable materials. 3 metal diaphragm valves machined surface dirt should be removed, and coated with anti-rust oil. Note to regular domestic oil cup grease. 4 rubber lining layer or the surface of the rubber diaphragm fat items are not brushing to avoid swelling and the impact of rubber valve life. 5 during storage or disabled, you should rotate the handwheel, the valve is in low lift state, to avoid prolonged pressure on the diaphragm due to loss of elasticity. 6 during transport or installation, the slings shall not be binding on the hand wheel or stem. And non-metal or other hard object impact to prevent damage to parts and rubber lining. 7 Before installation, the pipeline should be carefully checked whether the operating conditions and media scope of the valve in line and avoid using unnecessary losses caused by improper, and even accidents. 8 In addition to the road should not be used in vacuum tube can be installed anywhere in the pipeline for two-way flow, but should ensure that operating and maintenance convenience. 9 installation, the body cavity should be cleaned to prevent dirt jamming or damage sealing components, and check whether all components are fabric fastening bolts. 10 must always check the operation of parts in contact with the media, according to actual usage, regular replacement of wearing parts. 11 When replacing the diaphragm, the diaphragm should be careful not to tighten too tight or too loose. 12 used intermittent operation pipeline, then stop using, you should clean the contact area with the media, to extend the service life. 13 In the manual manipulation of diaphragm valves shall not open and close the valve by means of auxiliary lever, so as not to damage the drive torque is too large to seal part or parts. 14 by the diaphragm by the overhaul, the application prior to the testing requirements for sealing basis having tests certified before installation.

译文：
隔膜阀是一种特殊形式的截断阀，隔膜阀的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，故称隔膜阀。　　　　　　隔膜阀维护保养和安装使用注意事项：　　1. 隔膜阀应存放在干燥通风的室内，严禁堆迭放置。　　2. 库存隔膜阀的通路两端必须封口，以防止异物进入内腔而损伤密封部件。且应避免与油类或其他易燃物品接触。　　3. 隔膜阀的金属加工表面应清除污垢，并涂以防锈油。油杯内需经常注以润滑油脂。　　4. 衬胶层或橡胶隔膜表面切勿涂刷油脂类物品，以免产生橡胶溶胀而影响阀门使用寿命。　　5. 在存放期间或停用期间，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。　　6. 运输过程中或安装时，吊索不得系结在手轮或阀杆上。并严禁与其他金属或硬质物件撞击，以防止损伤零件和衬胶。　　7. 安装前，应仔细核对管路的运行条件及介质是否与本阀的适用范围相符，避免选用不当而造成不必要的损失，乃至发生意外事故。　　8. 除不宜应用于真空管路上，可在管路的任意位置安装作双向流动，但应确保操作和维修的方便。　　9. 安装前，应将阀体内腔清洗干净，防止污垢卡阻或损伤密封部件，并检查各部件连接螺栓是否均布紧固。　　10. 运行中必须经常检查与介质接触的部件，并按实际使用情况，定期更换易损部件。　　11. 当更换隔膜时，应注意切勿将隔膜拧得过紧或过松。　　12. 应用于间断性运行管路上，则在停止使用期间，应清洗与介质接触部位，以延长使用寿命。　　13. 在手动操纵隔膜阀时，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。　　14. 经经检修后的隔膜阀，在应用前，需按有关测试规定进行密封性试验合格后方能安装。
