The company has strong technical force, advanced production and testing equipment, superb production technology and strict management, reasonable prices, reliable quality, and improve after-sales service. The company has domestic advanced spray automatic assembly line, advanced production technology in Europe, large-scale production capacity, currently produces 2L-10000L expansion tank, diameter 400mm-2000mm of diaphragm pressure tank and 2L-5000L rubber balloon, is the country's largest, most models, matching the most complete expansion tank and air bag manufacturers. ? Fire pressure tanks, diaphragm pressure tank structure works: ?? diaphragm pressure tank is mainly due to the valve cover, inflatable mouth, air bags, steel tanks, flanges composition, when it is connected to the water system, mainly from the role of an accumulator when the system water pressure is greater than the expansion tank steel tanks under nitrogen pressure between the air bag, the system will squeeze into the water system under the action of pressure within the expansion tank balloon, so that one compresses between the nitrogen tank balloon, its volume decreases, the pressure increases; the second is to increase the entire water system accommodating space, the system pressure is reduced until the system water pressure and nitrogen in the tank between the airbag pressure to reach a new equilibrium stopped water. When the system water pressure is less than the gas pressure in the expansion tank, water balloon will be in the tank on the balloon between nitrogen pressure extrusion, fill back to the system, the system volume decreases water pressure increases, the bladder tank between nitrogen volume increases pressure drops, until both reach a new equilibrium, the water stops flowing from the airbag squeeze back into the system, stainless steel expansion tank pressure fluctuations play a regulatory role in the system. ?
