Introduction

Angle globe valve is a type of globe valve with an inlet and outlet angle of 90 ° C. In addition to the advantages and usage requirements of general flange globe valves, the biggest feature of this valve is that it is easy to install at the corners of pipeline systems, saving 90 ° C elbows and facilitating opening and closing operations. The flange angle globe valve is widely used in the synthetic ammonia system and refrigeration system of fertilizer plants.
角式截止阀是一种进口和出口呈90°C夹角的截止阀，这种阀门除了具备一般法兰截止阀的优点和使用要求外，最大的特点就是方便安装在管道系统的拐角处，既节省了90°C的弯头，又方便开闭操作。法兰角式截止阀在化肥厂的合成氨系统和制冷系统中等到非常广泛的应用。

J44H angle globe valve is only suitable for fully open and fully closed, and is not allowed to be adjusted or throttled. Globe valves belong to forced sealing valves, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve below, the resistance that the operating force needs to overcome is the frictional force between the valve stem and the packing, as well as the thrust generated by the pressure of the medium. The force required to close the valve is greater than that required to open it, so the diameter of the valve stem should be larger, otherwise the failure of the valve stem bending may occur.
J44H角式截止阀只适用于全开和全关，不允许作调节和节流.截止阀属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。当介质下方进入阀门时，操作力所需克服的阻力，是阀杆和填料的摩擦力与由介质的压力所产生的推力，关阀门的力比开阀门的大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。
