进口大口径焊接闸阀

进口焊接闸阀
简介：    
德国焊接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。
焊接闸阀,波纹管闸阀,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六时，操作力所需要克服的阻力，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力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。从自密封的阀门出现后，截止阀的介质流向就改由阀瓣上方进入阀腔，这时在介质压力作用下，关阀门的力小，而开阀门的力大，阀杆的直径可以相应地减少。同时，在介质作用下，这种形式的阀门也较严密。截止阀的流向，一律采用自上而下。焊接闸阀开启时，阀瓣的开启高度，为公称直径的25%～30%时，流量已达到***大，表示阀门已达全开位置。所以截止阀的全开位置，应由阀瓣的行程来决定。进口焊接闸阀适用于公称压力PN10.0-40.0Mpa,工作温度≤580℃的石油、化工、水力、火力电站各种系统的管路上,切断或接通管路介质。
German welded valve opening and closing parts are plug-shaped valve, le***ing it flat or cone seal centerline, the valve in a straight line along the fluid. Stem form of exercise with lifting rod (stem down, the hand wheel does not lift), but also lift rotating rod (hand wheel and stem rotation movements, nut located in the body). Bellows globe valves is only applicable to fully open and fully closed, does not allow for adjustment and throttle.
Welding valve, bellows valve, bellows sealed globe valves are forced valve, so when the valve is closed, the pressure must be applied to the valve to force the sealing surface does not leak. When the medium from the bottom of the six valve into the valve, the operating force required to overcome the resistance, frictional force and the thrust generated by the pressure medium and the valve stem packing, the valve off the valve opening force larger than the force, so that the valve The diameter of the rod to be large, otherwise the stem top corner of failures occur. From the emergence of self-sealing valve, globe valve to change the medium flow into the valve chamber from above the valve, then under media pressure, the valve off a ***all force, and force open the valve, the valve stem diameter can be accordingly reduced. Meanwhile, under the effect of the medium, this form of valve is also more closely. Off the flow valve, should be top-down. Welding valve open, the valve opening height for nominal diameter of 25% to 30%, the flow has reached the maximum, indicating that the valve has reached the fully open position. So closing the valve fully open position, the valve stroke should be determined. Imports of welded valve for nominal pressure PN10.0-40.0Mpa, pipeline petroleum, chemical, water, fire station and various system operating temperature ≤580 ℃, and cut off or connected to the line media.
进口焊接闸阀优点：结构简单，制造和维修比较方便。工作行程小，启闭时间短。密封性好，密封面间摩擦力小，寿命较长。
进口焊接闸阀缺点：流体阻力大，开启和关闭时所需力较大。不适用于带颗粒、粘度较大、易结焦的介质。调节性能较差。

进口焊接闸阀维护注意事项：
手轮、手柄操作的纹管截止阀可安装在管道的任何位置上。手轮、手柄及伟动机构，不允许作起吊用。介质的流向应与阀体所示箭头方向一致。焊接闸阀，也叫截门，是使用***广泛的一种阀门，它之所以广受欢迎，是由于开闭过程中密封面之间摩擦力小，比较耐用，开启高度不大，制造容易，维修方便，不仅适用于中 低压，而且适用于高压。它的闭合原理是，依靠阀杠压力，使阀瓣密封面与阀座密封面紧密贴合，阻止介质流通。焊接闸阀只许介质单向流动，安装时有方向性。它的结构 长度大于闸阀，同时流体阻力大，长期运行时，密封可靠性 不强。
