(穿板式)进口面板安装针型阀结构特征 structure characteristics

产品的设计符合ASME VIII，ANSI B16.34/B16.5B31.3 和API6D的相关要求  The product design shall conform to ASME VIII, ANSI B16.34/B16.5B31.3 and API6D

提供圆形手轮或一字手柄  Provide round handwheel or slotted handle

多种连接方式（螺纹、焊接、外螺纹活焊接、卡套）可选 Multiple connection methods (thread, welding, external thread movable welding, ferrule) are optional

阀瓣可变换为节流型、锥形、球型,可用以较精确的流量调节 The valve disc can be changed into throttling type, needle type and ball type for more accurate flow regulation

不旋转阀杆承受超高压和超高温 Non rotating valve rod withstands ultra-high pressure and ultra-high temperature

阀杆和填料函接头和阀体是相扣设计,绝对无泄漏，防止阀杆脱离阀门 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

填料位于阀杆的下方,以隔绝螺纹与介质的接触 The packing is located below the valve stem to isolate the contact between the thread and the medium

防火防爆结构，防止螺纹被流体介质所腐蚀结构 Fireproof and explosion-proof structure to prevent threads from being corroded by fluid medium
