Description

Technical Field

[0001] The present invention relates to the technical field of diaphragm accumulators, and particularly to a multi-branch air valve for a diaphragm accumulator. Background Art

[0002] A diaphragm accumulator is an accumulator that separates liquid and gas through a diaphragm. It usually consists of two diaphragms and a pressure accumulator. The principle of the diaphragm accumulator is to compress nitrogen or other gases into the pressure accumulator, so that the liquid on both sides of the diaphragm is under a certain pressure. Its inlet is generally directly connected to a gas pipe, and then connected to a nitrogen storage tank through the gas pipe for filling.

[0003] The currently used air valves have the following disadvantages:

[0004] 1. Currently, mainly one air valve is set at the top of the accumulator or one air valve is directly set in the middle of the gas pipe for partitioning, providing only a single truncation effect, which is not conducive to quickly guiding and releasing energy, and lacks a structure for multiple truncations and maintaining the gas transmission direction;

[0005] 2. Lack of a continuous monitoring structure triggered by pressure;

[0006] 3. Lack of a structure that can conveniently observe the amplitude change of the released pressure. Summary of the Invention
