摘要： Disclosed is a multifunctional anti-surge three orifices air valve set, comprising a negative pressure admitting valve (1), a small volumes release valve (2) and a mid-high rate venting valve (3) as well as a control isolating valve (4); the mid-high rate venting valve (3) is connected to the top of the negative pressure admitting valve (1) via aeration tube and the control valve, the two orifices being arranged separately rather than being common to each other, in order on the one hand to be selected individually to fulfil respectively the requirements for two different flow rates or speeds or calibers in a mid-high rate venting and a high-rate admitting, and on the other hand to conduct a composite admitting, at a negative pressure, of both flows of admitting air to complement each other; the independency of three orifices allows a high-speed admitting orifice and a small volumes air release orifice to combine and form a “macro-inject and micro-exhaust valve” or a “high-admitting and small-vent valve”, so that the valve set has the function of inhibiting the down-surge and up-surge due to column separation and rejoining cavity collapsing. The multi-function anti-surge three orifices air valve set has the function of the three orifices being independent of each other, the function of being able to be artificially turned off and then turned on, that is provided by the provision of a control isolating valve for the mid-high rate venting orifice, the function of combining the latter two functions to form a function with special effect, and the function of greatly reducing the high-rate discharge orifice.
