摘要： A clamp (41) for quick release of a generally rectangular bonnet (31) to the flange (22) of a valve body (21) is disclosed. The upper side of the edge of the rectangular bonnet (31) is formed with a bevel (39) of about 20 degrees and the lower edge of the body flange is formed with a similar bevel (28). The clamp (41) consists of semi-circular ends (48) and straight sides (46) hinged together. One side is split and connected by a toggle latch (62). In cross section, each clamp section is generally C-shaped, with the top and bottom arms (43) of the C being beveled so that as the clamp sections are drawn inward the bevels (28, 39, 43) wedge the bonnet (31) against the flange (22). Locating pins (37) fitting into holes (36) in the plate and flange locate the parts and resist implosion when the valve body (21) is subjected to vacuum. To maintain uniform clamping force around the circumference of the bonnet (31) the bevels (28) at the middles of the sides (24) may be less wide than at the ends (23).
