- Q41F美標法蘭球閥產(chǎn)品介紹
| Q41F美標法蘭球閥原理作用： |
| Q41F美標法蘭球閥性能特點： |
②防靜電裝置：當操作閥門時，由于球體和聚四氟乙烯等非金屬材料閥座之間摩擦，會產(chǎn)生靜電電荷并聚積在球體行。為防止產(chǎn)生靜電火花，特在閥門上設(shè)置防靜電裝置，把產(chǎn)生的靜電導(dǎo)出；
③防火結(jié)構(gòu)：本公司浮動球閥閥座采用獨特結(jié)構(gòu)，當發(fā)生火災(zāi)時，非金屬密封面材料燒毀時，金屬環(huán)利用彈簧的彈力推動閥座與球體吻合密封，從而阻止火勢蔓延和介質(zhì)外流；
④中部法蘭無外漏結(jié)構(gòu)：閥體與左體的連接部位是靠墊片密封，為防止由于火災(zāi)、高溫或震動等因素引起的該處密封泄露，特設(shè)計為閥體與左體金屬金屬接觸，形成止口法蘭，保證無外漏；
⑤自動泄壓結(jié)構(gòu)：當滯留在閥門中腔的介質(zhì)由于管道系統(tǒng)壓力或介質(zhì)溫度等因素引起的變化，從而出現(xiàn)中腔壓力異常升高時，中腔介質(zhì)能依靠本身的推力推動閥座而自動泄壓，從而確保閥門的安全。
