The buffer tank has two types of diaphragm type buffer tank and air bag type, and is widely applied to water supply equipment, central air-conditioning systems and other things; the direct contact type buffer tank, also called normal pressure type buffer tank, is filled with normal pressure gas, and the gas is in direct contact with the conveying liquid. The gas to be filled is generally air, and when flammable and explosive liquids are conveyed, inert gas should be filled. In addition, because the gas is directly contacted with the conveying liquid, part of the gas can be dissolved in the liquid (the dissolved amount is large under high pressure) and is carried away by the liquid. Therefore, a gas injection valve or gas injection equipment is arranged on the buffer tank so as to supplement air or inert gas; diaphragm type buffer tank is also called prepressing type buffer tank, and gas and liquid are separated by a diaphragm, and gas (air or nitrogen) with certain pressure is filled in advance when the diaphragm type buffer tank works. The diaphragm type surge tank is small in size compared with a direct contact type surge tank. And the gas is not contacted with the liquid, so that the property of conveying the liquid can be ensured, and the prior art has more applications.
