- 适用范围
- This part of ISO 19973 provides test procedures for assessing the reliability of pneumatic pressure regulators by testing and the methods of reporting the results of testing. General test conditions and the calculation method are provided in ISO 19973-1. The methods specified in ISO 19973-1 apply to the first failure, as obtained with the three-points moving average (3PMA) method, without repairs, but excluding outliers. The lifetime of pneumatic pressure regulators is usually given as a number of cycles. Therefore, whenever the term “time” is used in this part of ISO 19973, this variable shall be understood as either cycles or time. This part of ISO 19973 applies to manually adjustable and remote-piloted pressure regulators, both relieving and non-relieving. This part of ISO 19973 does not apply to pressure regulators that have a permanent bleed. This part of ISO 19973 also specifies test equipment and failure criteria (threshold levels) for tests to assess the reliability of pneumatic pressure regulators. The life determined by the method in this part of ISO 19973 and in ISO 19973-1 will be more closely related to applications that have a large variation in flow rate. NOTE See Annex A for a flow chart illustrating the test procedure specified in this part of ISO 19973.

仪表常见的30个故障及处理方法（温度、压力、流量、液位）
当空气压力增加时，阀门向关闭方向动作；空气压力减小或没有时，阀门向开启方向或全开为止。故有时又称为故障开启型（Fail to Open FO）。气动调节阀的气开或气关，通常是通过执行机构的正反作用和阀态结构的不同组装方式实现。2：常见的几个专业术语调节阀有执行机构和阀体部件两部分组成。调节阀一般采用气动薄膜执行机构，其作用方式有正，反两种。...
