美國(guó)仙童FAIRCHILD產(chǎn)品型號(hào)大全

FAIRCHILD減壓閥的作用原理是靠閥內(nèi)流道對(duì)水流的局部阻力降低水壓，水壓降的范圍由連接閥瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動(dòng)調(diào)節(jié)。定比減壓原理是利用閥體中浮動(dòng)活塞的水壓比控制，進(jìn)出口端減壓比與進(jìn)出口側(cè)活塞面積比成反比。這種減壓閥工作平穩(wěn)無振動(dòng)；閥體內(nèi)無彈簧，故無彈簧銹蝕、金屬疲勞失效之慮；密封性能良好不滲漏，因而既減動(dòng)壓（水流動(dòng)時(shí)）又減靜壓（流量為0時(shí)）；特別是在減壓的同時(shí)不影響水流量。
