Diaphragm valve maintenance and installation diaphragm valve is a special form of cut-off valve, diaphragm valve opening and closing parts is a material with a soft membrane made of, the body cavity with the valve cover cavity and drive components are separated, it said diaphragm. Diaphragm valve maintenance and installation notes: 1 diaphragm should be stored in dry and ventilated room, place the stacked prohibited. Channel 2 ends of inventory must be sealed diaphragm, to prevent foreign body into the cavity and damage the sealing parts. And should avoid contact with oil or other combustible materials. Metal surface 3 diaphragm valves should remove dirt, and coated with anti rust oil. Note to regular domestic oil cup grease. 4 lining layer or rubber membrane surface fat items are not brushing, lest produce and affect the service life of the valve rubber swelling. 5 during the storage period or stop, should be in counter clockwise direction, so that the valve is in the open state of micro, avoid the diaphragm and lose their elasticity due to prolonged pressure. 6 transport or installation, slings shall not be bound in the hand wheel or valve stem. And no impact and other metal or hard objects, in order to prevent damage to parts and rubber lining. 7 before the installation, should check the pipeline operating conditions and the medium carefully is consistent with the scope of the valve, caused by improper selection to avoid unnecessary losses, and even accidents. 8 in addition to should not be used in vacuum tubes, can be installed anywhere in the pipeline for two-way flow, but should ensure that the operation and repair convenience. 9 before the installation, should be the body cavity clean, prevent dirt jamming or damage to seal components, and check all parts of the connecting bolts are tightened uniformly. To inspect and the medium contact part frequently run in the 10, and according to the actual conditions, the replacement of wearing parts regularly. 11 when the replacement of the diaphragm, the diaphragm should pay attention do not screw too tight or too loose. 12 application to intermittent operation of the pipeline, the stop during use, should be clean and the medium contact spot, to extend the service life. 13 in the manual diaphragm valve, not by means of auxiliary lever to make the valve opened and closed, to avoid too large torque and the damage driving parts or sealing parts. 14 after the diaphragm valve after the repair, in the application, shall be sealed test according to the relevant provisions of qualified test installation.隔膜阀的维护保养和安装使用。

隔膜阀的维护保养和安装使用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。隔膜阀的维护保养和安装使用。
