進(jìn)口塑料隔膜閥(德國奧萊斯OLES品牌)
【進(jìn)口塑料隔膜閥】詳細(xì)說明：
進(jìn)口全塑隔膜閥于控制一般腐蝕性介質(zhì)，可供各類管路或設(shè)備上作啟閉及節(jié)流用。采用*技術(shù)、一次注塑成型。以聚偏二氟乙烯(PVDF)、增強聚丙烯(RPP)、氯化聚氯乙烯(CPVC)、硬聚氯乙烯(UPVC)等材質(zhì)生產(chǎn)的隔膜閥具有質(zhì)輕、無毒、無污染、耐高溫、耐腐蝕、耐壓、機械強度高、密封不泄漏、操作靈敏、拆裝方便、可隨意調(diào)節(jié)流量等特點，可取代金屬、金屬襯里、陶瓷等產(chǎn)品。
隔膜閥是一種特殊形式的截斷閥，它的啟閉件是一塊用軟質(zhì)材料制成的隔膜，把閥體內(nèi)腔與閥蓋內(nèi)腔及驅(qū)動部件隔開。隔膜把下部閥體內(nèi)腔與上部閥蓋內(nèi)腔隔開，使位于隔膜上方的閥桿、閥瓣等零件不受介質(zhì)腐蝕，省去了填料密封結(jié)構(gòu)，且不會產(chǎn)生介質(zhì)外漏。以壓縮空氣為動力帶動傳動螺桿，使閥芯上下運動，同時拉動膜片上下運動使其關(guān)閉和打開。
The imported full plastic diaphragm valve is specially designed for controlling general corrosive media, and can be used for opening and closing and throttling of various pipelines or equipment. It adopts advanced technology and one-time injection moulding. The diaphragm valves made of polyvinylidene fluoride (PVDF), reinforced polypropylene (RPP), chlorinated polyvinyl chloride (CPVC), rigid polyvinyl chloride (UPVC) and other materials have the characteristics of light weight, non-toxic, non-polluting, high temperature resistance, corrosion resistance, high pressure resistance, high mechanical strength, non-leakage sealing, sensitive operation, convenient disassembly and assembly, and optional flow regulation. Replace metal, metal lining, ceramics and other products.
Diaphragm valve is a special type of cut-off valve. Its opening and closing parts are a diaphragm made of soft material, which separates the inner chamber of valve body from the inner chamber of valve cover and driving parts. The diaphragm separates the inner chamber of the lower valve body from the inner chamber of the upper valve cover, so that the parts such as the stem and disc above the diaphragm are not corroded by the medium, thus eliminating the packing sealing structure and producing no leakage of the medium. The drive screw is driven by compressed air, which makes the valve core move up and down, and pulls the diaphragm up and down to close and open.
【進(jìn)口塑料隔膜閥】結(jié)構(gòu)特點：
1.適用于腐蝕介質(zhì)的輸送及截流、流量的調(diào)節(jié)，根據(jù)材質(zhì)不同使用溫度-14℃～100℃、-40℃～140℃。 2.過流部件彩RPP或PVDF注塑件組裝而成，耐腐蝕性能優(yōu)良，操作方便，體量輕，能代替不銹鋼閥門。 3.密封件膜片采用F46或PFA制造，耐折次數(shù)≥1200次，耐腐蝕性能與F4相當(dāng)。 4.采用螺桿升降結(jié)構(gòu)，啟閉力矩大，平穩(wěn)性好。
安裝說明：
1.兩端法蘭與管路連接時，要均勻擰緊螺栓，防止法蘭變形，造成泄漏。 2.順時針方向旋手柄為關(guān)閉，反之開啟。 3.根據(jù)指示器位置可判斷開啟程度。
【進(jìn)口塑料隔膜閥】特點：
突出特點是隔膜把下部閥體內(nèi)腔與上部閥蓋內(nèi)腔隔開，使位于隔膜上方的閥桿、閥瓣等零件不受介質(zhì)腐蝕，省去了填料密封結(jié)構(gòu)，且不會產(chǎn)生介質(zhì)外漏
1、采用橡膠或塑料等軟質(zhì)密封制作的隔膜，密封性較好。由于隔膜為易損件，應(yīng)視介質(zhì)特性而定期更換。
2、受隔膜材料限制，隔膜閥適用于低壓和溫度相對不高的場合。
3、隔膜閥按結(jié)構(gòu)形式可分為：屋式、直流式、截止式、直通式、閘板式和直角式六種；連接形式通常為法蘭連接；按驅(qū)動方式可分為手動、電動和氣動三種，其中氣動驅(qū)動又分為常開式、常閉式和往復(fù)式三種。
4.一般不宜用于溫度高于60度及輸送有機溶劑和強氧化介質(zhì)的管路中，也不宜在較高壓力的管路中使用
