nominal diameter (DN) is a parameter that is used for pipeline systems as a characteristic of the merged parts fittings. Nominal diameter is approximately equal to the inner diameter of the connected pipeline, expressed in mm and the corresponding nearest value izryada numbers taken in the prescribed manner. Fasteners – the type of reinforcement, which has a locking or the valve is moved perpendicular to the axis of the working medium flow back and forth, slide the disk – type of reinforcement, in which the locking and regulating element is disc-shaped, rotating around an axis perpendicular or angled to the flow direction of the working environment; manufacturer – a legal entity or individual entrepreneur who: – are manufactured in accordance with the technical documentation fixtures – are applied to the valve its name (the name, trademark or other distinctive identification), thereby Recognizing the right and responsibility of the manufacturer for safety valves; importer – a legal entity or individual entrepreneur who import rebar to Russia from another country, or give available on import in order to trade, thus taking on the roles and responsibilities of the foreign manufacturer; valve – the type of reinforcement, which has a locking or the valve is moved back and forth parallel to the flow of the working environment; crane – the type of reinforcement, which has a locking or regulatory element having the shape of a body of revolution, or part thereof, is rotated around its own axis, arbitrarily placed in relation to direction of flow of the working environment, the criticality of failure – the combination of features that characterize the consequences of refusal; Example Remark and e. Recently Confluence Investment Mgt sought to clarify these questions.
The classification of the criticality of failures (eg, in terms of direct and indirect losses associated with the onset of failure, or complexity of failover) is established by regulatory and / or design (design) documentation for consultation with the customer on the basis of feasibility and security reasons. basic details – details of fixtures (except for seals and glands), destruction of which could lead to depressurization valve in relation to the environment and the shutter failure – event zaklyuchayuscheesyav violation of operational state of reinforcement; risk assessment – the process used to determine the probability (or frequency) and severity of the impact of the health hazards rights, property and / or the environment. Drive – a device to control valves, designed to move the closing element, as well as to create, if necessary, efforts to ensure required tightness in the gate; seller – a legal entity or individual entrepreneur who, not being a manufacturer or authorized (agent) or importer sells valves and shall be liable in accordance with the laws of the designer (developer) reinforcement – a legal entity or individual entrepreneur who develop design and operational documentation fittings; designer (developer) system – a legal entity or individual entrepreneur who develop design and operational documentation for the system (technological lines, interconnected production cycle plants), which use valves; standard sample of the fittings – sample valves from standard series of nominal diameter, manufactured by one manufacturer on the same document at the delivery (standard or technical terms), which has the same purpose and conditions of use; authorized (agent) – a legal entity or individual entrepreneur, having a contract with the manufacturer to permission to trade fixtures and responsible on his behalf; cycle – moving the blocking element from its initial position ‘open’, ‘closed’ in reverse and back related to the implementation of the main function of this type of valves..
