配资盘介紹

産品主要優點Product main advantages
 
1.波紋管密封閘閥,其關鍵部件金屬波紋管,下端與閥杆組件采用自动滾焊焊.接,上端與連接闆自动滾焊焊接,在流體介質和大氣之間形成一個金屬屏障,确保閥杆零洩漏。
 
2.閥瓣采用錐形設計,密封面與介質成流線形,密封性能更好,使用壽命更長。3.雙重的密封設計(波紋管+填料)若波紋管不幸失效,閥杆填料也會避免洩漏,并符合國際密封标準。
 
1. Bellows seal gate valves, it is a key component of metal bellows, bottom stem adopts automatic seam welding and welding, the upper connection plateautomatic welding seam welding, between the fluid and the atmosphere toform a metal barrier, to ensure that the valve stem zero leakage.
 
2. The disc adopts the design of conical sealing surface and medium into a streamlined, better sealing performance, long service life.
 
3. Double seal design (bellows + packing) if the bellows unfortunately fails, stem packing also can avoid leakage, and conform to the international standardof sealing.
