进口气动调节隔膜阀（德国OLES奥莱斯阀门）

进口气动调节隔膜阀(德国OLES奥莱斯阀门)

【进口气动调节隔膜阀】详细说明：

气动常闭(开)型调节隔膜阀是气动隔膜阀、气动衬胶隔膜阀、气动衬氟隔膜阀的更新产品。在开发过程中全部运用了现在的技术。已经有大份额的产品被用户所接受和使用。精小型隔膜阀的接口尺寸与之相同，可直接替代更换。气动常闭(开)型调节隔膜阀由隔膜阀、气动执行器组合而成：它的动力是压缩空气，是为了调节管道流体介质的流量。在结构设计方面，精小型隔膜阀采用了耐腐蚀性能较强的隔膜片，这种无填料形式、节流元件的弹性隔膜，其阀体的流道平坦光滑，故气动调节隔膜阀有以下的优点：1、阻力小。2、流量大。3、零泄漏。4、可靠方便。5、防爆防火。综上所述，正因为有这些优点，所以气动隔膜阀在强碱、强酸、高粘度、强腐蚀性、含有颗粒、带纤维以及有毒和不允许污染的介质的流量调节的工业自动化领域中得到了广泛的运用。隔膜阀的启闭形式来源于管道对增强橡胶隔膜的压力作用。它的工作原理是，当阀门控制腔充满压力介质时，便下压隔膜，阀门通道被关闭，控制腔内的压力介质排入大气和下游通道，隔膜将上升，继而打开阀门通道。阀门零件的构造及其简单，没有阀杆、密封垫等，隔膜片作为一个在通道流通中唯1能运动的零件部分，它本身就具有很强的耐腐蚀性，所以不会出现生锈腐蚀的情况。具有不同形式的结构和控制方式，可满足不同的流体控制需求。

The pneumatic normally closed (open) type regulating diaphragm valve is an updated product of pneumatic diaphragm valve, pneumatic lining diaphragm valve and pneumatic lining fluorine diaphragm valve. In the process of development, all the latest technologies are used. A large share of products have been accepted and used by users. The interface size of the fine and small diaphragm valve is the same as that of the valve, which can be replaced directly. The pneumatic normally closed (open) regulating diaphragm valve is composed of a diaphragm valve and a pneumatic actuator. Its power is compressed air, which is used to regulate the flow of fluid medium in the pipeline. In terms of structure design, small and fine diaphragm valves adopt diaphragm with strong corrosion resistance. This kind of elastic diaphragm without filler and throttle elements has smooth flow passage. Therefore, pneumatic control diaphragm valves have the following advantages: 1. Small resistance. 2. Large flow. 3. Zero leakage. 4. Reliable and convenient. 5. Explosion-proof and fire-proof. In summary, because of these advantages, pneumatic diaphragm valves have been widely used in the field of industrial automation for flow regulation of strong alkali, strong acid, high viscosity, strong corrosiveness, containing particles, fibers and toxic and non-polluting media. The opening and closing form of diaphragm valve comes from the pressure effect of pipeline on strengthening rubber diaphragm. Its working principle is that when the valve control chamber is filled with pressure medium, the diaphragm is pressed down, the valve passage is closed, the pressure medium in the control chamber is discharged into the atmosphere and downstream passage, and the diaphragm will rise, and then the valve passage is opened. The structure of valve parts and its simplicity, no stem, gasket, etc., diaphragm as the only moving part in the channel flow, it itself has a strong corrosion resistance, so there will be no rust corrosion. Different structures and control modes can meet different fluid control requirements.

【进口气动调节隔膜阀】特性：

隔膜阀是在阀体和阀盖内装有一挠性隔膜或组合隔膜，其关闭件是与隔膜相连接的一种压缩装置。阀座可以是堰形，也可以是直通流道的管壁。隔膜阀的优点是其操纵机构与介质通路隔开，不但保证了工作介质的纯净，同时也防止管路中介质冲击操纵机构工作部件的可能性。此外，阀杆处不需要采用任何形式的单独密封，除非在控制有害介质中作为安全设施使用。隔膜阀中，由于工作介质接触的仅仅是隔膜和阀体，二者均可以采用多种不同的材料，因此该阀能理想地控制多种工作介质，尤其适合带有化学腐蚀性或悬浮颗粒的介质。隔膜阀的工作温度通常受隔膜和阀体衬里所使用材料的限制，它的工作温度范围大约为－50～175℃。隔膜阀结构简单，只由阀体、膜片和阀头组合件三个主要部件构成。该阀易于快速拆卸和维修，更换隔膜可以在现场及短时间内完成
