汽水阀门的阀盘和阀座是决定其运行可靠性的极重要部件.在较大的单位压力条件下打开的关闭闸板时阀盘和阀座的接触面上伴随着相互摩擦力.在起动和运行过程中阀盘和阀座经受着流动介质,温度以及在起动过程中可能落入流动介质中的固体微粒(水垢,氧化皮等)的作用.闸板表面单位负载配合着闸板移动促使形成磨伤、缺口、裂纹、裂纹也可能由起动和停用时的温差引起. The valve plate and seat of the soda valve are extremely important components that determine the reliability of their operation. The valve plate and valve seat contact surfaces are frictional with each other when the valve plate is opened under large unit pressure conditions. And the valve disk and valve seat are subjected to the action of the flowing medium, the temperature and the solid particles (scale, scale, etc.) that may fall into the flowing medium during starting. The unit load of the shutter surface cooperates with the movement of the shutter The formation of abrasions, nicks, cracks, cracks may also be caused by the start and stop the temperature difference.
