進(jìn)口超高壓球閥(Flange high pressure ball valve)—美國(guó)威盾VTON,采用一體式高壓鍛造閥體,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。
High pressure ball valve, one-piece high-pressure forged valve body, in Class 150 ~ 2500LB Operating Temperature -28 to 300 ° C in the petroleum, chemical, fire station and other conditions of the pipeline, its safety, resistance to harsh environments such as design have been special consideration, suitable medium: water, steam, oil, nitric acid, acetic acid, urea and other corrosive and strong oxidizing medium. The mode of operation: manual, pneumatic, electric, hydraulic and gas-liquid interaction.
進(jìn)口法蘭高壓球閥特點(diǎn):
1、進(jìn)口法蘭高壓球閥中腔停滯的壓力異常超過(guò)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(wàn)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、進(jìn)口法蘭高壓球閥的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。
