(穿板式)進口面板安裝針型閥結(jié)構(gòu)特征 structure characteristics

產(chǎn)品的設(shè)計符合ASME VIII，ANSI B16.34/B16.5B31.3 和API6D的相關(guān)要求  The product design shall conform to ASME VIII, ANSI B16.34/B16.5B31.3 and API6D

提供圓形手輪或一字手柄  Provide round handwheel or slotted handle

多種連接方式（螺紋、焊接、外螺紋活焊接、卡套）可選 Multiple connection methods (thread, welding, external thread movable welding, ferrule) are optional

閥瓣可變換為節(jié)流型、錐形、球型,可用以較精確的流量調(diào)節(jié) The valve disc can be changed into throttling type, needle type and ball type for more accurate flow regulation

不旋轉(zhuǎn)閥桿承受超高壓和超高溫 Non rotating valve rod withstands ultra-high pressure and ultra-high temperature

閥桿和填料函接頭和閥體是相扣設(shè)計,絕對無泄漏，防止閥桿脫離閥門 The valve stem, stuffing box joint and valve body are designed to be interlocked, absolutely without leakage, to prevent the valve stem from leaving the valve

填料位于閥桿的下方,以隔絕螺紋與介質(zhì)的接觸 The packing is located below the valve stem to isolate the contact between the thread and the medium

防火防爆結(jié)構(gòu)，防止螺紋被流體介質(zhì)所腐蝕結(jié)構(gòu) Fireproof and explosion-proof structure to prevent threads from being corroded by fluid medium
