進口對焊波紋管截止閥
進口對焊波紋管截止閥的閥桿采用波紋管及填料雙重密封結(jié)構(gòu)，確保閥桿處的無泄漏密封，特別適用于易燃、易爆、有毒及貴重介質(zhì)的管路。波紋管采用不銹鋼或 Inconel材料制造，波紋管密封結(jié)構(gòu)設計合理，耐疲勞，使用壽命長。波紋管截止閥廣泛適用于公稱壓力PN1.6～4.0MPa,工作溫度-29～350℃的石油、化工、制藥、化肥、電力行業(yè)等各種工況的管路上，切斷或接通管路介質(zhì)。
The import of welded bellows valve
Imported welded bellows globe valve stem with corrugated pipe and packing a double seal structure, ensure no leakage at the valve stem seal, the pipeline is especially suitable for the inflammable and explosive, toxic and expensive medium. The corrugated pipe is made of stainless steel or Inconel material, the bellows seal structure is reasonable in design, fatigue resistance and long service life. Bellows globe valve is widely used in nominal pressure PN1.6 ~ 4.0MPa, the operating temperature of -29 to 350 DEG C petroleum, chemical, pharmaceutical, chemical fertilizer, electric power industry and other working conditions of the pipeline, cut off or connect the pipeline media.
