Abstract

See full text

A main valve for a straightway deluge valve includes a valve body (1), a valve cover (2), a diaphragm (3), a drawing piston (4), a diaphragm pressure plate (5), a drawing link (6), a valve body link (7), a valve plate link (8), a rotatable lip and a mounting hole cover (13). A piston guide is provided at a side part of the valve body (1). The drawing piston (4) is provided slidably in the piston guide along a left-right direction. When the drawing piston (4) slides along the piston guide, the rotatable lip can contact with or separate from the inner sealing end surface. The main valve for drawing the straightway deluge valve, after the valve plate (9) is opened, enables the flow passage to be close to a straightway passage, thereby reducing flow loss.
