德国TOP托普进口丝扣闸阀/html/2028.html
德国TOP进口铸钢丝扣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。丝扣闸阀,内螺纹闸阀,高压闸阀,纹管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。当介质由阀瓣下方进入阀体时，操作力所需要克服的阻力，是阀杆和填料的磨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力大，所以阀杆的直径要大，否则会发生阀杆**弯的故障。

Germany imported TOP top threaded valve:
Germany imported TOP cast steel wire buckle valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Threaded valve, threaded gate valve, high pressure valve, bellows valve is forced closed valve, so the valve is closed, the valve must exert pressure to force the sealing surface does not leak. When the medium into the valve body from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault.
