41、EN 736-2 4 Requirements 4.1 Design 4.1.1 Construction 4.1.1.1 General The valve shall be of either concentric design (see Figure 6) or eccentric design (see Figure 7). The offset may be single, double or triple. Figure 6 Concentric design Figure 7 Eccentric design (example of double offset design) T
42、he design details are the responsibility of the manufacturer. 4.1.1.2 Body Flanges of double flanged valves and single flange wafer valves shall have bolt holes in accordance with the relevant standard as specified in 4.1.4.2. Threaded holes can be provided where the design of the valve precludes th
43、rough flange bolting. Flangeless wafer valves (see Figure 2) are intended for clamping between pipe flanges using through bolting. The shape of wafer valve bodies shall be such that centring of the valves within the appropriate flange bolt BS EN 593:2009+A1:2011EN 593:2009+A1:2011 (E) 9 circle is en
44、sured. Where through bolting is not practicable due to the valve design, e.g. close to shaft passages, threaded holes can be provided for individual bolting. Lugged or single flange wafer valves (see Figure 3) are supplied with threaded or through holes for installation between two flanged component
45、s or at the end of a pipeline (i.e. end of line service or downstream dismantling). Threaded holes shall allow full thread engagement to a depth at least equal to the nominal bolt diameter and at least 0,67 of the bolt diameter when the bolt hole is adjacent to the valve shaft. For Class designed va
46、lves threaded body flange holes for bolts 1 inch or less in diameter shall be drilled and tapped in accordance with ASME B1.1, UNC coarse thread series, Class 2B. For bolts 1 1/8 inches or more in diameter, such holes shall be drilled and tapped in accordance with ASME B1.1, UN 8 eight thread series
47、, Class 2B. Threads according to other standards shall be specified. The manufacturers literature shall be consulted to determine if through bolting or/and end of line assembly is possible. Any limitation regarding end of line service condition shall be indicated. Elastomeric or plastic linings and
48、liners can be extended over the flange faces of the body to form a gasket for the flange. 4.1.1.3 Obturator (disc) The valve manufacturers technical documentation shall specify all necessary dimensions showing the protrusion of the obturator in the open position beyond the faces of the valve. 4.1.1.
49、4 Seat seal or body liner The valve manufacturers technical documentation shall specify whether the seat seal or body liner is replaceable or non-replaceable. 4.1.1.5 Driving shaft The external end of the driving shaft shall indicate the orientation of the obturator. The shaft shall indicate by design or marking the position of the obturator. Where required by the design of valve, the m
