Water pipelines the valve is suitable for the work temperature ≤ 80 ℃, the highest point installed in horizontal pipeline, to exclude the gas pipeline and when the negative pressure inside the pipeline air when inhaled, so as to avoid pipeline failure.
Double outlet width is big, small two cavity, a big mouth suction, exhaust, small mouth can be in line with water under the condition of small exhaust suction, its main function is to prevent the pipeline to produce negative pressure when the pump stops, causing pipeline failure.
