一、进口锻钢螺纹闸阀概述

进口锻钢螺纹闸阀，Forged steel threaded valve，是指采用内螺纹的连接方式，阀体采用整体一体式锻造方式，锻打制造的闸阀，具有耐高压，密封性好的特点。适用于 Class150~2500 、工作温度 -29～425℃（碳钢）或 -29～500℃（不锈钢）的小口径管路上，用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质

内螺纹锻钢闸阀的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。阀杆的运动形式，有升降杆式（阀杆升降，手轮不升降），也有升降旋转杆式（手轮与阀杆一起旋转升降，螺母设在阀体上）。纹管截止阀只适用于全开和全关，不允许作调节和节流。

Forged steel threaded valve refers to a gate valve that uses an internal thread connection method, and the valve body adopts an integral forging method. It is forged and manufactured with the characteristics of high pressure resistance and good sealing. Suitable for small diameter pipelines with Class150~2500 and operating temperatures of -29~425 ℃ (carbon steel) or -29~500 ℃ (stainless steel), used to cut off or connect the medium in the pipeline. Different materials are selected and can be used for various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc

The opening and closing part of the internal threaded forged steel gate valve is a plug shaped valve disc, with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the fluid. The movement forms of the valve stem include the lifting rod type (valve stem lifting, handwheel not lifting), as well as the lifting rotating rod type (handwheel and valve stem rotating together to lift, nut installed on the valve body). The corrugated tube globe valve is only suitable for fully open and fully closed, and cannot be adjusted or throttled.
