1.气动调节器的输出压力为什么有时会突然消失?为了说明这个问题,本文先从结构谈起,且主要介绍波纹管式气动调节器,而不是膜片式的.调节器的输出压力突然消失常常是由挡板喷嘴机构引起的.目前,仪表用户使用的波纹臂式调节器有较大部分为挡板喷嘴机构.这种挡板喷嘴机构的主要缺点有两点:一是不易封盖.为了输出压力稳定,挡板必须能够全面地封盖喷嘴.但全面封盖在装配上是不十分容易
1. Why is the output pressure of the pneumatic regulator suddenly disappearing? To illustrate this problem, we start with the structure and mainly introduce the bellows-type pneumatic regulator instead of the diaphragm type. The output pressure of the regulator abruptly disappears Often caused by the bezel nozzle mechanism.At present, the corrugated arm adjuster used by instrument users has a large part of bezel nozzle mechanism.The main drawbacks of this bezel nozzle mechanism are two points: First, it is not easy to cover. In order to stabilize the output pressure, the baffle must be able to fully cover the nozzle, but the full closure in the assembly is not very easy
