Constant pressure water device for use ● production, fire, life pressurized water system Wanted constant pressure water system, commonly referred capsule automatic water supply equipment. ● used for heating, air-conditioning system as a regulator expanded replenishment device, commonly known as capsule landing expansion tank. When the pressure reaches the design pressure, through the pressure controller makes up pump is turned off. When the thermal expansion of water within the system so that the system pressure increases the role of the constant pressure water device exceeds the design pressure, excess water to fill the tank through the safety valve discharge cycle use, when water in the system since the leak or the temperature drops and the volume is reduced at constant pressure replenishment device, the system pressure drops, capsules water is continuously pressed into the pressure drop in the pipe network constant pressure water replenishment system device profiles, when the system pressure to a minimum design pressure of time allowed by the pressure controller makes up the water pump to restart pipelines and water pressure tank, again and again. Constant pressure water device profiles, Hongshan constant pressure water equipment, Wuhan Han Wei Wei Li Yuen Yuen provided by the Wuhan-being of Equipment Co., Ltd. Wuhan Han Wei Li Yuen-being of Equipment Co., Ltd. (www.whhwly.com) strong, credible, in Wuhan, Hubei fan, ventilation equipment industry has accumulated a large number of loyal customers.
