36、e purpose of this European Standard the terms and definitions listed in EN 736-1, EN 736-2 and EN 736-3 apply, together with the following : 3.1 weir type diaphragm valve diaphragm valve in which closure is attained by compression of the diaphragm onto a raised weir formed in the body shape 3.2 stra
37、ight through type diaphragm valve diaphragm valve in which closure is attained by compression of the diaphragm onto the valve body wall, the body maintaining a largely straight-through bore configuration 3.3 diaphragm flexible component, generally of either elastomeric or polymeric material, which d
38、oes not form part of the pressure bearing shell but acts as the valve obturator, whilst also isolating the valve mechanism from the line fluid 3.4 com pressor component of the diaphragm valve assembly which affords compression to the diaphragm to effect closure against the valve body 4 Requirements
