Abstract

The invention relates to a novel V-type diaphragm valve. The novel V-type diaphragm valve comprises a diaphragm valve body, wherein one end, in a horizontal direction, of the diaphragm valve body is a water inlet, and the other end of the diaphragm valve body is a water outlet; the middle part of the diaphragm valve body is provided with a control cavity; a running water channel is arranged below the control cavity; a rubber diaphragm is arranged in the control cavity; a spring is arranged between the rubber diaphragm and a position above the control cavity; a hydraulic or gas pressure control opening is formed in the upper part of the control cavity; a waterproof lug boss is arranged at the inner side of the lower part of the control cavity; and the two ends of the rubber diaphragm are arranged within the wall of the diaphragm valve body. The novel V-type diaphragm valve is simple in structure, is good in corrosion resistance, is stable and reliable to operate, is low in manufacturing cost and is less in daily maintenance quantity.
