Supply CARX-I Shanghai Composite quick exhaust valve exhaust valve manufacturer spot wholesale products

One. Structure and use of the valve body is barrel-shaped, the valve stainless steel ball valve stem and the valve member is included. The valve installed in the pump outlet or water pipeline transmission and distribution, to exclude the accumulated air in the tube, in order to improve the efficiency of the pipeline and the pump, when the inner tube when a negative pressure, the valve quickly sucked outside air, in order to prevent damage due to the negative pressure line. II. When works begin when the inner tube water injection valve in the open position, a lot of exhaust, when the air is drained, filled with water inside the valve, the float rises and promote the valve closed to stop the exhaust pipe when the normal water When delivery, if a small amount of air accumulated in the valve to a certain extent, water level dropped valve, float fall, when the air is discharged from the hole. When the pump stops, generating a negative pressure in the water pipe or a case of empty inner tube, then quickly turned plugs, intake air, to ensure pipeline safety. Three.
