進(jìn)口襯膠隔膜閥,(德國(guó)OLES奧萊斯閥門品牌)
【進(jìn)口襯膠隔膜閥】詳細(xì)說明：
精小型氣動(dòng)活塞隔膜調(diào)節(jié)閥由隔膜閥和氣動(dòng)執(zhí)行機(jī)構(gòu)兩部分組成，它以壓縮空氣為動(dòng)力，實(shí)與對(duì)工藝管道中流體介質(zhì)流量的調(diào)節(jié)。由于在結(jié)構(gòu)上采用帶有耐腐蝕襯里的閥體和耐腐蝕的隔膜、無填料函結(jié)構(gòu)、節(jié)流元件為彈性隔膜、閥體流道平滑，故氣動(dòng)薄膜隔膜閥具有陰力小，流量大、無外漏和方便可靠、防火防爆的優(yōu)點(diǎn)，廣泛適用于工業(yè)自動(dòng)化系統(tǒng)中的強(qiáng)酸、強(qiáng)堿、強(qiáng)腐蝕、高粘度、含穎粒、帶纖維以及有毒和不充許污染的介質(zhì)的流量調(diào)節(jié)。 隔膜閥的關(guān)閉與開啟是通過來自管路的壓力作用于增強(qiáng)橡膠隔膜實(shí)現(xiàn)的。當(dāng)壓力介質(zhì)進(jìn)入閥門控制腔，隔膜下壓，關(guān)閉閥門通道，當(dāng)控制腔壓力排向大氣或下游管道，隔膜上升，閥門通道被打開。閥門沒有閥桿、密封墊、定向座等，通道中運(yùn)動(dòng)的唯1部件就是隔膜，所以不存在銹蝕及抱死現(xiàn)象，具有更高的穩(wěn)定性。多種結(jié)構(gòu)形式及控制形式，可適用于多種的流體控制需要 。
The diaphragm control valve of fine and small pneumatic piston consists of diaphragm valve and pneumatic actuator. It is powered by compressed air and regulates the flow rate of fluid medium in the process pipeline. Pneumatic membrane diaphragm valves are widely used in industrial automation systems because of their advantages of small negative force, large flow rate, no leakage, convenience, reliability, fire and explosion protection, because they are constructed with corrosion-resistant body and corrosion-resistant diaphragm, non-stuffing box structure, elastic diaphragm as throttle element and smooth flow passage of valve body. Flow regulation of strong acid, strong alkali, strong corrosion, high viscosity, glumes, fibers and toxic and non-polluting media. The closing and opening of the diaphragm valve is realized by the pressure from the pipeline acting on the reinforced rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm is pressed down and the valve passage is closed. When the pressure of the control chamber is discharged into the atmosphere or downstream pipeline, the diaphragm rises and the valve passage is opened. Valves have no stem, gasket, directional seat, etc. The only moving part in the passage is the diaphragm, so there is no rust and lock phenomenon, which has higher stability. Various structural forms and control forms can be applied to a variety of fluid control needs.
