上述的均压措施在铰销轴方向不能自动均压，需要在装配中人工调好。对于口径较小的阀门，由于绝对误差量较小，在装配中容易调好，但对于口径较大的阀门，就困难得多。因此对于大口径阀门应采用完全自动均压的措施。例如图28所示的结构，采用球而压头就能完全自动均压。

阀板的传动机构有两个职能：一是使阀板压紧密封圈，保证阀门的密封性能;二是使阀板开启后，阀门有较大的流导。承担第一个职能的机构零件，由于受力较大、有强度、刚度和稳定性问题，设计中需要考虑。这些机件是传动机构中的主要构件，承担第二个职能的机件主要使阀板按所需要的位置开启，因此受力不大，零件的强度等问题是次要的。R900437702 FMH 20 G14-1X/O

一般的真空阀门，其阀板的压紧机构就是其传动机构，例如图7、图8、图12、图14等。这类传动机构，只要知道了阀板压紧机构的压紧力，就可以按照普通机械传动进行设计了。
