【產(chǎn)品說明】
進(jìn)口固定高壓球閥—美國(guó)威盾VTON,適用于Class 150~2500LB,工作溫度-28~300℃的石油、化工、火力電站等各種工況的管路上,其安全、耐惡劣環(huán)境性等的設(shè)計(jì)均已進(jìn)行特殊考慮,適用介質(zhì)為:水、蒸汽、油品、硝酸、醋酸、尿素等腐蝕性和強(qiáng)氧化性介質(zhì)。操作方式有:手動(dòng)、氣動(dòng)、電動(dòng)、液動(dòng)和氣液聯(lián)動(dòng)等。
進(jìn)口固定高壓球閥特點(diǎn):
1、閥門中腔停滯的壓力異常超過彈簧的預(yù)緊力時(shí),閥座后退脫離球體,達(dá)到自動(dòng)泄壓的效果,卸壓后閥座自動(dòng)復(fù)位。 2、當(dāng)萬一發(fā)生火災(zāi)或由于異常升溫使閥座密封圈燒損或軟化時(shí),在彈簧和介質(zhì)壓力作用下,使支撐圈球面部位和球體形成金屬對(duì)金屬接觸,達(dá)到暫時(shí)密封作用,阻止了火災(zāi)進(jìn)一步擴(kuò)大,符合API 6FA的規(guī)定。 3、填料壓蓋部位密封采用PTFR填料和0形密封圈雙重密封圈,特別適用于氣體介質(zhì),填料裝在填料盤內(nèi),可隨時(shí)采用摩擦系統(tǒng)低的新型SF型自潤(rùn)滑滑動(dòng)軸襯,減低操作力矩。
