复合式排气阀
Compound exhaust valve
产品概述
复合式排气阀阀体为圆桶状，阀门内件包括不锈钢浮球、杠杆及阀瓣。本阀安装在泵出口处或配水管线中，用来排除集积在管中的空气，以提高管线及水泵的使用效率，当管内一旦产生负压时，此阀迅速吸入外界空气，以防止管线因负压而损坏。当管内开始注水时，阀瓣处在开启的为置，进行大量排气，当空气排完时，阀内充满水，浮球上升并带动阀瓣关闭，停止排气，当管内水正常输送时，如有少量空气聚集在阀内到相当的程度，阀内水位下降，此时空气由小孔排出。当水泵停止时，管内水流空或遇管内产生负压，此时塞头迅速开启，吸入空气，确保管线安全。介质温度：0~80℃
Product Overview
The valve body of the compound exhaust valve is cylindrical, and the inner parts of the valve include stainless steel float, lever and valve disc. The valve is installed at the pump outlet or in the water distribution pipeline to remove the air collected in the pipe to improve the efficiency of the pipeline and the pump. When negative pressure is generated in the pipe, the valve quickly inhales the outside air to prevent the pipeline from being damaged due to negative pressure. When the pipe begins to fill with water, the valve disc is in the open position for a large amount of exhaust, when the air is discharged, the valve is filled with water, the float rises and drives the valve disc to close, stop the exhaust, when the water in the pipe is normally transported, if there is a small amount of air gathered in the valve to a certain extent, the valve water level drops, at this time the air is discharged by the small hole. When the pump stops, the water flow in the pipe is empty or negative pressure is generated in the pipe, and the plug head is quickly opened to inhale air to ensure the safety of the pipeline.
