Abstract

The invention relates to a V-shaped double-sided diaphragm valve. The V-shaped double-sided diaphragm valve comprises a diaphragm valve body, wherein a sprue is formed in the middle of the diaphragm valve body; an upper rubber diaphragm is arranged at the position, above the sprue, in the diaphragm valve body; an upper spring is arranged between the upper rubber diaphragm and the inner top wall of the diaphragm valve body; a lower rubber diaphragm is arranged at the position, below the sprue, in the diaphragm valve body; a lower spring is arranged between the lower rubber diaphragm and the inner bottom wall of the diaphragm valve body; one end of the diaphragm valve body in the horizontal direction is a water inlet, and the other end of the diaphragm valve body in the horizontal direction is a water outlet; the upper rubber diaphragm and the lower rubber diaphragm are symmetrically arranged; the left end and the right end of the upper rubber diaphragm are both horizontally arranged at the upper part of the diaphragm valve body; the left end and the right end of the lower rubber diaphragm are both horizontally arranged at the lower part of the diaphragm valve body; a hydraulic power control opening or an air pressure control opening is formed in each of the upper end and the lower end of the diaphragm valve body. The V-shaped double-sided diaphragm valve is suitable for large-caliber occasions, and is excellent in corrosion resistance, steady and reliable in operation, low in manufacturing cost and less in daily maintenance.

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. Single-sided diaphragm valves cannot meet some large-diameter pipeline occasions. 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 V-type double-sided diaphragm valve suitable for large-caliber occasions, with good anti-corrosion performance, stable and reliable operation, low manufacturing cost and less daily maintenance. [0004] Technical solution: In order to solve the above tec...
