Introduction

New process measurement and control instruments, including valve positioners, most with microprocessors for digital data processing and communication

Letter methods and/or artificial intelligence make these instruments more complex and add significant value.

Today's smart valve positioners are no longer just controlling the position of the valve, in many cases with self-tests, actuators/valves

Various functions such as door status monitoring and alarm. There are a wide variety of new features, far from being comparable to a single-function "cam-type" positioner. Therefore, with

Accuracy-related performance tests, while still very important, are not sufficient to demonstrate the flexibility, capability, and design of smart valve positioners.

Features such as work, installation, maintainability, reliability and operability.

The assessments described in this section take into account both hardware and software performance testing and design reviews. The structure of this section is arranged to a certain extent

The framework of IEC /T S62098 "Methods for the evaluation of microprocessor-based instruments" is followed. Some performance tests described in GB/T 22137.1

Still suitable for smart valve positioners. It is recommended to further read the IEC 61069 "Systematic Measurement of Industrial Process Measurement and Control Systems"

Part 2. Smart Valve Positioner

Performance evaluation method

1 Scope

This part of GB/T 22137 specifies the performance evaluation method for single-acting or double-acting intelligent valve positioners (hereinafter referred to as positioners).

Method to test and determine the static and dynamic performance, intelligence and communication of intelligent valve positioners through design reviews and tests

ability.

This section applies to receiving standard analog input signals (see IEC 60381) and/or digital signals transmitted via data communication links.

Intelligent valve positioner with pneumatic output. As defined in Chapter 3, the intelligent valve positioner is a data processing, decision generation

A meter that implements its functions with digital technologies such as two-way communication. It can be equipped with additional sensors and additional features to support its main features.

The performance test of the intelligent valve positioner requires the positioner to be installed and connected to the associated actuator/valve assembly. Due to

The performance of the positioner is highly dependent on the actuator used, so some characteristic parameters of the assembly, such as size, stroke, friction

The source pressure (return), stuffing box type, spring assembly and pneumatic part should be carefully selected and reported.

The assessment methods specified in this section are intended to be used by test laboratories to verify the performance of the positioner. Recommended locator manufacturers in the early days

This standard is used during the development phase.

This section is intended to provide guidance for the design assessment of the positioner by providing.

--- Review the checklist of intelligent valve positioner hardware and software design according to the structural method;

--- Test methods for measuring and determining the performance of intelligent valve positioners under different environmental conditions and working conditions;

--- Reporting method of test data.

When it is not required or impossible to conduct a comprehensive assessment in accordance with this section, the necessary tests may be carried out and reported in accordance with the relevant provisions of this section.

Test results. In this case, the test report should indicate that it does not include all the test items specified in this section. In addition, it is also suitable

Mentioning omitted items gives the reader of the report a clear idea.

This section also applies to non-intelligent valve positioners with microprocessors but without two-way communication. In this case, performance evaluation

It should be simplified to a defined performance test plan and a brief structural review.
