Non-negative pressure secondary water supply equipment
The invention relates to non-negative pressure secondary water supply equipment. The non-negative pressure secondary water supply equipment comprises a water inlet main pipe and a control system, anda pressure transmitter and a backflow preventer are arranged on the water inlet main pipe. A first non-negative pressure tank comprises a first tank body and a center pipe, a small hole is formed in the center pipe, and the center pipe is sleeved with an elastic bag. A main water supply assembly comprises a first pipeline, and the first pipeline communicates with multiple first branches and a first variable-frequency water pump. An auxiliary water supply assembly comprises a second pipeline, and a bidirectional converter is arranged on a conversion branch. A second non-negative pressure tank comprises a second tank body, and the interior of the second tank body is separated into an upper airtight second air cavity and a lower water cavity by an elastic film. The pressure transmitter and anelectro connecting pressure gauge are arranged on a water outlet main pipe. The pressure of the water inlet end and the water outlet end of the equipment both can be kept constant, the water supply amount can be adaptively adjusted according to the water use amount of users, and energy is saved.
本发明涉及一种无负压二次供水设备。包括进水进水主管，进水主管上设有压力变送器和倒流防止器；第一无负压罐包括第一罐体和中心管，中心管上设有小孔，中心管的外部还套设有弹性袋；主供水组件包括第一管路，第一管路上连通有多个第一支路和第一变频水泵；副供水组件包括第二管路，转换支路上设有双向转换器；第二管路的一端设有第二无负压罐，第二管路上设有第二变频水泵；第二无负压罐包括第二罐体，第二罐体内通过弹性膜将第二罐体分隔为上部密闭的第二气腔和下部的水腔；出水主管上设有压力变送器和电接点压力表；控制系统。该设备的进水端和出水端压力均能保持恒定且可根据用户用水量大小适应性的调整供水量、比较节能。
