進(jìn)口氣動(dòng)調(diào)節(jié)隔膜閥(德國OLES奧萊斯閥門)

【進(jìn)口氣動(dòng)調(diào)節(jié)隔膜閥】詳細(xì)說明：

氣動(dòng)常閉(開)型調(diào)節(jié)隔膜閥是氣動(dòng)隔膜閥、氣動(dòng)襯膠隔膜閥、氣動(dòng)襯氟隔膜閥的更新產(chǎn)品。在開發(fā)過程中全部運(yùn)用了現(xiàn)在的技術(shù)。已經(jīng)有大份額的產(chǎn)品被用戶所接受和使用。精小型隔膜閥的接口尺寸與之相同，可直接替代更換。氣動(dòng)常閉(開)型調(diào)節(jié)隔膜閥由隔膜閥、氣動(dòng)執(zhí)行器組合而成：它的動(dòng)力是壓縮空氣，是為了調(diào)節(jié)管道流體介質(zhì)的流量。在結(jié)構(gòu)設(shè)計(jì)方面，精小型隔膜閥采用了耐腐蝕性能較強(qiáng)的隔膜片，這種無填料形式、節(jié)流元件的彈性隔膜，其閥體的流道平坦光滑，故氣動(dòng)調(diào)節(jié)隔膜閥有以下的優(yōu)點(diǎn)：1、阻力小。2、流量大。3、零泄漏。4、可靠方便。5、防爆防火。綜上所述，正因?yàn)橛羞@些優(yōu)點(diǎn)，所以氣動(dòng)隔膜閥在強(qiáng)堿、強(qiáng)酸、高粘度、強(qiáng)腐蝕性、含有顆粒、帶纖維以及有毒和不允許污染的介質(zhì)的流量調(diào)節(jié)的工業(yè)自動(dòng)化領(lǐng)域中得到了廣泛的運(yùn)用。隔膜閥的啟閉形式來源于管道對(duì)增強(qiáng)橡膠隔膜的壓力作用。它的工作原理是，當(dāng)閥門控制腔充滿壓力介質(zhì)時(shí)，便下壓隔膜，閥門通道被關(guān)閉，控制腔內(nèi)的壓力介質(zhì)排入大氣和下游通道，隔膜將上升，繼而打開閥門通道。閥門零件的構(gòu)造及其簡單，沒有閥桿、密封墊等，隔膜片作為一個(gè)在通道流通中唯1能運(yùn)動(dòng)的零件部分，它本身就具有很強(qiáng)的耐腐蝕性，所以不會(huì)出現(xiàn)生銹腐蝕的情況。具有不同形式的結(jié)構(gòu)和控制方式，可滿足不同的流體控制需求。

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.

【進(jìn)口氣動(dòng)調(diào)節(jié)隔膜閥】特性：

隔膜閥是在閥體和閥蓋內(nèi)裝有一撓性隔膜或組合隔膜，其關(guān)閉件是與隔膜相連接的一種壓縮裝置。閥座可以是堰形，也可以是直通流道的管壁。隔膜閥的優(yōu)點(diǎn)是其操縱機(jī)構(gòu)與介質(zhì)通路隔開，不但保證了工作介質(zhì)的純凈，同時(shí)也防止管路中介質(zhì)沖擊操縱機(jī)構(gòu)工作部件的可能性。此外，閥桿處不需要采用任何形式的單獨(dú)密封，除非在控制有害介質(zhì)中作為安全設(shè)施使用。隔膜閥中，由于工作介質(zhì)接觸的僅僅是隔膜和閥體，二者均可以采用多種不同的材料，因此該閥能理想地控制多種工作介質(zhì)，尤其適合帶有化學(xué)腐蝕性或懸浮顆粒的介質(zhì)。隔膜閥的工作溫度通常受隔膜和閥體襯里所使用材料的限制，它的工作溫度范圍大約為－50～175℃。隔膜閥結(jié)構(gòu)簡單，只由閥體、膜片和閥頭組合件三個(gè)主要部件構(gòu)成。該閥易于快速拆卸和維修，更換隔膜可以在現(xiàn)場及短時(shí)間內(nèi)完成
