Through this technical proposal, an environmentally friendly pressurized water tank is added at a high level, so that the frequency conversion water pump can be operated with as large a load as possible without damaging the pressure of the municipal pipe network. The work greatly shortens the working time of the variable frequency water pump, thereby making up for the shortcomings in the prior art.

所述气压罐中气罐与水囊之间充装有一定初始压力的倍压补偿气，气罐外侧设置有与气罐内相连通的气体补偿口，在气体补偿口上设置有节门。The air tank and the water bag in the air tank are filled with pressure doubler compensation gas with a certain initial pressure, and a gas compensation port communicating with the inside of the gas tank is provided on the outside of the gas tank, and a throttle is provided on the gas compensation port.
本实用新型在实际应用中，变频水泵工作，叠加市政管网压力向高位环保密闭水箱供水，当市政管网压力远高于规定压力下限时，变频水泵在工频状态下满负荷运转，当市政管网压力临近规定压力下限时，变频水泵经压力变送器或远程压力表，在变频状态下低负荷运转，以保证市政管网压力稳定的情况下安全供水；通过势能向用户管网供水，对于用户管网中势差较大的用户可以直接从高位环保密闭水箱供水，而对于用户管网中势差较小的用户可以通过在高位环保密闭水箱输出端设置微动力水泵和气压罐，微动力水泵工作增加用户管网压力，当用户管网压力大于气压罐内倍压补偿气时，水进入气压罐的水囊中使水囊体积增大，气压罐内倍压补偿气压力同时升高，当用户管网压力低于气压罐内倍压补偿气的压力时，气体压迫水囊，将水囊中的水补充到用户管网中。In the practical application of the utility model, the frequency conversion water pump works, and the pressure of the municipal pipe network is superimposed to supply water to the high-level environmental protection airtight water tank.
