耐腐蚀PVDF进口气动塑料法兰隔膜阀
品牌:美国威盾VTON
进口气动塑料PVDF隔膜阀由耐酸的塑料材质PVDF隔膜阀和气动执行机构两部分组成,它以压缩空气为动力,实与对工艺管道中流体介质的开关和流量的调节。
由于在结构上采用带有耐腐蚀衬里的阀体和耐腐蚀的隔膜、无填料函结构、节流元件为弹性隔膜、阀体流道平滑,故气动薄膜隔膜阀具有阴力小,流量大、无外漏和方便可靠、防火防爆的优点。
◆特点
1、无填料函,节流元件为弹性隔膜,可以做到关闭时无内外漏;
2、流路平滑,流阻小,具有很大的流通能力;
3、外表精美、体积小、重量轻、输出力大;
4、偏氟塑料PVDF或者UPVC的阀体和聚四氟乙烯的隔膜使其耐腐蚀性能更强、工作寿命更长;
◆参数
尺寸:DN15-DN200
压力等级:≤PN10
适用温度:-10℃+60℃
阀 体:UPVC,PVDF
阀 盖:UPVC,PVDF
隔 膜:PTFE+FPDM

◆ 应用场合:广泛适用于工业自动化系统中的强酸、强碱、强腐蚀、高粘度、含颖粒、带纤维以及有毒和不充许污染的介质的流量调节。
进口气动隔膜阀的安装使用说明
气动隔膜阀想对比手动隔膜阀,增加了气动执行器和其它的电磁阀,限位开关等附件,在安装和使用中相对于手动隔膜阀复杂得多,一些知名的进口隔膜阀品牌,都有说明书,比如美国威盾VTON的进口气动隔膜阀,随货都带有使用说明书,但很多用户经常弄丢,那么,本文就再详细介绍下;
1. 进口气动隔膜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.
2. 口气动隔膜阀应避免与液体燃料、油料或其它易燃物品接触。
Should be avoided with liquid fuel, oil or other flammable materials contact.
3. 进口气动隔膜阀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
4. 安装前,应仔细核对管路使用条件是否与进口气动隔膜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
4. 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.
5. 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
6. 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
7. 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
8. 进口气动隔膜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
9. 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
15.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.
16.当需恢复气动操作时,必须首先旋转手轮至气缸内留有 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
故障排查和解决方法:
可能发生的故障 Possible fault | 原因 | 消除方法 |
进口气动隔膜阀手轮转动不灵活 Hand wheel rotation is not flexible | 阀杆上积有污垢或螺纹损伤。 阀杆螺母磨损或拉裂。 阀杆弯曲。 Dirt or the valve stem threaded plot injury 2、Stem nut wear or cracking 3. Stem bending | 清除污垢或修整螺纹并涂以润滑油。 更换阀杆或螺母。 校正或更换阀杆。 1. Remove dirt or trim threads and coated with oil 2. Replace the valve stem or nuts 3. Correction or replacement of stem
