10、nal foreword This Part of BS 5793 has been prepared under the direction of the Industrial-process Measurement and Control Standards Committee. It is identical with IEC Publication 534-1:1987 “Industrial-process control valves Part 1: Control valve terminology and general considerations”, published b
11、y the International Electrotechnical Commission (IEC). In 1993 the European Committee for Electrotechnical Standardization (CENELEC) accepted IEC 534-1:1987 as European Standard EN 60534-1:1993. As a consequence of implementing the European Standard this British Standard is renumbered as BS EN 60534
12、-1 and any reference to BS 5793-1 should be read as a reference to BS EN 60534-1. Terminology and conventions. The text of the international standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with
13、 those used in British Standards; attention is drawn especially to the following. Where the words “IEC Publication 534” appear in clause 1, they should be read as “BS 5793”. Where the words “parts of IEC Publication 534” appear in clause 1 and note 2 to 4.2, they should be read as “Parts of BS 5793”
14、. The Sections of Parts of IEC 534 referred to in clause 2 as “In preparation” will become identical Sections of Parts of BS 5793 when published as IEC documents in a form acceptable to the Industrial-process Measurement and Control Standards Committee. The Technical Committee has reviewed the provi
15、sions of IEC 534-3-1, 1)ISO 2084, ISO 2229, ISO 6708 and ISO 7268 (with Amendment 1), to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard.

41、 A valve in which a flexible closure member isolates the line fluid from the actuating mechanism and provides a seal to the atmosphere. 3.1.1.2 Gate valve A valve whose closure member is a flat or wedge-shaped gate that is moved linearly across the seat. 3.1.1.3 Globe valve A valve with a globular-s
42、haped body whose closure member moves in a direction perpendicular to the plane of the seat. 3.1.2 Control valves with a rotary motion closure member 3.1.2.1 Ball valve A valve with a closure member that is either a sphere with an internal passage or a segment of a spherical surface. The axis of the
43、 spherical surface is coincident with the axis of the shaft. 3.1.2.2 Butterfly valve A valve with a circular body and a rotary motion disk closure member, pivotally supported by its shaft. 3.1.2.3 Plug valve A valve with a closure member that may be cylindrical, conical or an eccentric spherical seg
44、ment in shape. 3.2 Valve An assembly forming a pressure retaining envelope containing internal means for changing the flow rate of the process fluid. 3.2.1 Valve body The part of the valve which is the main pressure retaining boundary. It provides the fluid flow passageways and the pipe connecting e
45、nds. 3.2.1.1 Nominal size (DN) A numerical designation of size which is common to all components in a piping system other than components designated by outside diameters or by thread size. It is a convenient round number (corresponding approximately to the internal diameter of the connection to the
46、pipework expressed in millimeters) for reference purposes and is only loosely related to manufacturing dimensions. NOTE 1It is designated by DN followed by a number from the following series: 10, 15, 20, 25, 32, 40, 50, 65, 80, 100, 125, 150, 200, 250, 300, 350, 400, etc. NOTE 2The nominal size DN c
47、annot be subject to measurement and shall not be used for purposes of calculation. NOTE 3Some older international standards refer to nominal size as nominal diameter but, for the purpose of this standard, the two terms are synonymous. NOTE 4The definition of nominal size is in accordance with ISO St
48、andard 6708. 3.2.1.2 Nominal pressure (PN) A numerical designation which is a convenient round number for reference purposes. All equipment of the same nominal size (DN) designated by the same PN number shall have compatible mating dimensions. NOTE 1The maximum allowable working pressure depends upo
49、n materials, design and working temperatures and should be selected from the pressure/temperature rating tables in the appropriate standards. NOTE 2It is designated by PN followed by the appropriate reference number from the following series: 2.5, 6, 10, 16, 20, 25, 40, 50, 100, 150, 250, 420. NOTE 3The PN ratings are based on recommendations of the ISO. PN 2.5, 6, 10, 16, 25 and 40 ratings are based on the flange system designated in ISO Standard 2084. PN 20, 50, 100, 150, 250 and 420 ratings are based on the flange sys
