產品簡介：
本閥安裝在泵出口處或配送水管線中，用來排除集積在管中的空氣，以提高管線及水泵的使用效率，當管內一旦產生負壓時，此閥迅速吸入外界空氣，以防止管線因負壓而損壞。它具有結構緊湊輕巧、造型美觀，耐磨，使用壽命長等特點。
Product Brief Introduction:
The valve is installed in the pump outlet or water distribution pipeline to remove the air in the tubes, so as to improve the use efficiency of the pipeline and the water pumps, when the negative pressure come into being in the tubes, the valve will inhale the air outside rapidly to prevent the pipeline’s damage due to negative pressure. There are many traits on it such as the structure compact and legerity, sculpt beauty, wearable and long service life.
