从自密封的阀门出现后，法兰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。我国阀门三化给曾规定，截止阀的流向，一律采用自上而下。氧气截止阀使用维护情况如下：使用维护的目的，在于延长氧气截止阀寿命和保证启闭可靠。阀杆螺纹，经常与阀杆螺母摩擦，要涂一点黄干油、二硫化钼或石墨粉，起润滑作用。

吹洗应注意事项如下：吹洗气体或液体必须是被测工艺对象所允许的流动介质,通常它应满足下列要求:a.与被测工艺介质不发生化学反应；清洁，不含固体颗粒；通过节流减压后不发生相变；无腐蚀性；流动性好。吹洗液体供应源充足可靠，不受工艺操作影响。吹洗流体的压力应高于工艺过程在测量点可能达到的高压力，保证吹洗流体按设计要求的流量连续稳定地吹洗。采用限流孔板或可调阻力的转子流量计测量和控制吹洗液体或气体的流量。

合理的设置低通滤波器的截止频率，将放大器的频带限制在一个适当的范围，就能使试验机的测量控制性能得到极大的提高。然而在现实中，人们往往将数据的稳定显示看的非常重要，而忽略了数据的真实性，将滤波器的截止频率设置的非常低。这样在充分滤掉干扰信号的同时，往往把有用信号也一起滤掉了。在日常生活中，我们常见的电子秤，数据很稳定，其原因之一就是它的频带很窄，干扰信号基本不能通过。这样设计的原因是电子秤称量的是稳态信号，对称量的过渡过程是不关心的，而材料试验机测量的是动态信号，它的频谱是非常宽的，若频带太窄，较高频率的信号就会被衰减或滤除，从而引起失真。
