4516A *仙童FAIRCHILD減壓閥飛兆4000A型號(hào)是一款無(wú)泄漏高流量精密壓力調(diào)節(jié)器,專為要求高性能,低功耗和精確過程控制的應(yīng)用而設(shè)計(jì)。4000A型氣動(dòng)調(diào)節(jié)器具有小于0.5“水柱的控制靈敏度,zui小消耗量和高流量能力,可提供始終如一且可靠的精度精度,從而無(wú)論供應(yīng)壓力變化或條件如何,都能保持所需的設(shè)定點(diǎn)??商幚?50 psi,17 BAR的zui大供應(yīng)壓力,并提供0.5-10 psi,0.03-0.7 BAR,3-70 kPa至5-250 psi,0.35-17 BAR,35-1700 kPa的五(5) 。4000A型的流量可達(dá)150 SCFM,255 m3 / hr。
4516A *仙童FAIRCHILD減壓閥屬于先導(dǎo)活塞式減壓閥。由主閥和導(dǎo)閥兩部分組成。主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設(shè)定出口壓力、利用膜片傳感出口壓力變化,通過導(dǎo)閥啟閉驅(qū)動(dòng)活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小,實(shí)現(xiàn)減壓穩(wěn)壓功能。本產(chǎn)品主要用于氣體管路,如空氣、氮?dú)狻⒀鯕?、氫氣、液化氣、天然氣等氣體
注意事項(xiàng)
1.為了操作和維護(hù)方便,該閥一般直立安裝在水平管道上。
2.減壓閥安裝必須嚴(yán)格按照閥體上的箭頭方向保持與流體流動(dòng)方
向*。如果水質(zhì)不清潔,含有一些雜質(zhì),必須在減壓閥的上游進(jìn)水口安裝過濾器。
3.為了防止閥后壓力超壓,應(yīng)在離閥出口不少于4M處安裝一個(gè)減壓閥。
4.減壓閥在管道中起到一定的止回作用,為了防止水錘的危害,也可安裝小的膨脹水箱,防止損壞管道和閥門,過濾器必須安裝在減壓閥的進(jìn)水管前,而膨脹水箱必須安裝在減壓閥出水管后!
5.如果需要將減壓閥安裝在熱水系統(tǒng)時(shí),您必須在減壓閥和膨脹水箱之間安裝止回閥。這樣既可以讓膨脹水箱吸收由于熱膨脹而增加的水的體積,又可以防止熱水回流或壓力波動(dòng)對(duì)減壓閥的影響,確保減壓閥長(zhǎng)期正常工作。
