ISO 22435:2024 specifies design, type test methods, marking and instruction requirements for cylinder valves with integrated pressure regulators (VIPRs) intended to be fitted to gas cylinders, pressure drums or tubes or used as a main valve for bundles of cylinders that convey compressed, liquefied or dissolved gases.
本文件规定了具有集成压力调节器(vipr)的钢瓶阀的设计、型式试验方法、标志和指令要求，这些阀门拟安装在气瓶、压力鼓或管道上，或用作输送压缩、液化或溶解气体的钢瓶束的主阀。
Valves with integrated pressure regulators (VIPRs)are used to reduce the pressure receptacle pressure to alower pressure suitable for end use processes.
VIPRs incorporate the basic functionality of a primary valve operating mechanism,with the additional ability to regulate the pressure and/or flow at the valve outlet.They remove the need for end users to makeand break a high-pressure gas connection.
These valves operate over a wide range of inlet and outlet pressures and flows which require specific design characteristics.It is important that the operating characteristics of these valves be specified and tested in adefined manner.
Such valves are more complicated than conventional cylinder valves yet subject to the same environmental and transport conditions.These conditions should be kept in mind at the design and development stage.
This document gives additional requirements for VIPRs to those given for cylinder valves in general in ISO 10297,for quick-release cylinder valves in ISO 17871,for self-closing cylinder valves in ISO 17879 or forball valves in ISO 23826.
