Study on Performance of the Exhaust Valve in Water Supply and Drainage Engineering

Gas cannot prompt emission is the main reason for Water pipeline burst, explore the exhaust valve's performance at present, which has practical significance for the pipeline safety protection.Through the experiment, research the commonly used exhaust valve in water supply and drainage engineering and comparison of theirs exhaust performance.Respectively summarizes the applicable conditions of the currently used exhaust valve.Gave performance evaluation for both at home and abroad exhaust valve. Thus solves the pipeline burst question because the gas cannot prompt emissions specially in long distance water distribution pipeline of actual project .
