伺服比例閥D31FTB32CC5NF00

伺服比例閥D31FTB32CC5NF00　這種連接適用于各種壓力和溫度，在較荷刻的條件下使用時，比法蘭連接更為可靠。但是焊接連接的閥門拆卸和重新安裝都比較困難，所以它的使用限于通常能長期可靠地運行，或使用條件荷刻、溫度較高的場合。如火力發(fā)電站、核能工程、乙烯工程的管道上。 D31FBB32CC4NG00(老型號D31FTB32CC4NG00)

　　公稱通徑在50mm以下的焊接閥門通常具有焊接插口來承接荷平面端的管道。由于承插焊接在插口與管道間形成縫隙，因而有可能使縫隙受到某些介質(zhì)的腐蝕，同時管道的振動會使連接部位疲勞，因此承插焊接的使用受到一定的限制。 D41FHB31C2NE00 派克比例換向閥 D41FHB31C2NE0048

　　在公稱直徑較大，使用條件荷刻，溫度較高的場合，閥體常采用坡口對焊接，同時，對焊接縫有原格要求，必須選用技術(shù)過硬的焊工完成此項工作。  D41FHB61B2NB00 派克比例換向閥 D41FHB61B2NB0048
