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.

Description

technical field [0001] The invention relates to a valve structure, in particular to a diaphragm valve structure. Background technique [0002] Conventional V-type diaphragm valve: the valve body is made of cast iron, cast steel, and stainless steel; there are valve shafts and seals on the water passage. It has the problems of heavy overall mass, high manufacturing cost, complex structure, poor anti-corrosion performance, etc., and has a large amount of daily maintenance and low reliability. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a new V-type diaphragm valve with simple structure, good anti-corrosion performance, stable and reliable operation, low manufacturing cost and less daily maintenance. [0004] Technical solution: In order to solve the above technical problems, a novel V-shaped diaphragm valve according to the present invention includes a diaphragm valve ...
