一、进口锻钢波纹管截止阀概述

进口锻钢波纹管截止阀（威盾VTON），Forged steel bellows globe valve，也叫锻造波纹管截止阀，锻钢高压波纹管截止阀，锻钢法兰波纹管截止阀，锻钢焊接波纹管截止阀，是指采用整体锻造的，能耐高压力的波纹管密封截止阀。

锻钢波纹管截止阀有二种阀盖设计形式.第一种是螺栓式阀盖,按这种设计形式设计的阀门,其阀体与阀盖用螺栓螺母连接,缠绕式垫片(304夹柔性石墨制造)密封.客户有特殊要求时也可采用金属环连接.第二种设计形式是焊接式阀盖,扫这种设计形式设计的阀门,其阀体与阀盖用螺纹连接,全焊密封.客户有特殊要求时也可采用透焊接连接。

Forged steel bellows globe valve (VTON), also known as Forged steel bellows globe valve, Forged steel high-pressure bellows globe valve, Forged steel flange bellows globe valve, Forged steel welded bellows globe valve, refers to a bellows sealed globe valve that uses integral forging and can withstand high pressure.

There are two types of valve cover design for forged steel corrugated pipe globe valves. The first type is a bolt type valve cover. Valves designed according to this design form are connected to the valve body and valve cover with bolts and nuts, and sealed with a spiral wound gasket (made of 304 flexible graphite). When customers have special requirements, metal ring connection can also be used. The second design form is a welded valve cover. For valves designed in this design form, the valve body and valve cover are connected with threads and fully welded. When customers have special requirements, penetration welding connection can also be used.
