Novel air tank structure for protecting-pump water supplying system

The invention discloses a novel air tank structure for a protecting-pump water supplying system. The novel air tank structure comprises an air tank, a pressure reduction valve, a high-temperature air storage tank and a check valve. The air tank is connected with the high-temperature air storage tank through an air transmitting pipe, the check valve, a normally-opened electromagnetic valve, the pressure reduction valve and a service valve are sequentially arranged in the air transmitting pipe, and the air tank is also sequentially connected with a normally-closed electromagnetic valve and the air valve. The novel air tank structure has the advantages that the protection effect of a water hammer is good; the installing position is not limited by the topographic condition, and the novel air tank structure is universally installed nearby a water pump room; the structure is simple, running is safe and reliable, using is convenient, and maintaining is easy. 种防护泵供水系统水锤用的新型空气罐结构，包括空气罐、减压阀、高压储气罐、止回阀，所述空气罐与高压储气罐通过输气管路连
