What Is The Basic Content of the Valve Design?
What is the basic content of the valve design? Let's see it in this article.
As an important part of the piping system, we need to ensure the safety and reliability of the piping system to the use of the valve requirements. Therefore, the valve design must meet all the requirements put forward by the working medium pressure, temperature, corrosion, fluid characteristics and operation, manufacturing, installation, maintenance and other aspects of the valve.
The valve design must specify the given technical data, which is the "design input", upon which the design can be correctly completed.
The basic data required for valve "design input"
Purposes or types of valves
The working pressure of the medium
A working diagram of the medium
Physical and chemical properties of the medium (corrosive, inflammable and explosive, toxic, physical state, etc.)
Nominal menstruation
The length of the structure
The form of connection to the pipe
The valve operation mode (manual, gear drive, worm gear drive, electric, pneumatic, hydraulic, etc.)
In the valve technical design and work drawing design, we should master the data and technical requirements.
The flow capacity and fluid resistance coefficient of valves
The opening and closing speed and closing times of valves
Driving device energy characteristics (AC or DC, voltage, air pressure, etc.)
The working environment and maintenance conditions of valves (whether explosion-proof, whether tropical weather conditions, etc.)
External size limitation
Limit weight
Seismic resistance requirements
Design procedure of valves
Design and development planning
Design and development phase
Review, validation, and validation activities that are appropriate to each design and development phase
Responsibilities and authority for design and development
Design and development inputs
Functional and performance requirements
The use of legal and regulatory requirements
Information previously provided by similar designs
Other requirements necessary for design and development
Design and development outputs
Meet the requirements of design and development inputs
Give appropriate information on procurement, production and service provision
Contains or references to product acceptance standards
Specify the product characteristics that are necessary for the safe and proper use of the product
Design and development validation of design and development changes by way of product validation.
