High-efficiency energy-saving full-automatic back-flush non-negative-pressure water supply device

Abstract

The invention relates to a high-efficiency energy-saving full-automatic back-flush non-negative-pressure water supply device, and belongs to the field of water supply devices. The water supply device mainly comprises a support. A flow stabilizing tank, a booster pump, an energy accumulator and a control cabinet are arranged on the support. A negative pressure eliminator and a pressure gauge are arranged on the flow stabilizing tank. The inlet end is connected with a tap water pipe network controlled by a water inlet electronic control valve, and the outlet end is connected with a water inlet main pipe. One end of the water inlet main pipe is connected with a drain pipe controlled by a drainage electronic control valve. The inlet end of the booster pump is connected with the water inlet main pipe, and the outlet end is connected with a water outlet main pipe through a check valve and a valve. A pressure gauge is arranged on the water outlet main pipe. A bypass pipe is connected between the water inlet main pipe and the water outlet main pipe. The water inlet and the water outlet of the energy accumulator are connected with the water outlet main pipe through the electronic control valve. A cleaning device composed of an annular pipe, branch pipes and spraying nozzles is arranged in the flow stabilizing tank. The inlet of the cleaning device is connected with the water outlet end of a back-flush water pump.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving fully automatic backwashing non-negative pressure water supply equipment, which belongs to the field of water supply equipment. Background technique [0002] With more and more high-rise buildings, the use of secondary water supply equipment is becoming more and more extensive. At present, although the known non-negative pressure water supply equipment can make full use of the pressure of municipal tap water, there is a problem that the water pump cannot be stopped in order to maintain the pressure of the pipe network when the user does not use water, resulting in unnecessary waste of electric energy. , At the same time, there is still sludge deposited in the steady flow tank, which is not easy to clean up, thus causing pollution to tap water and affecting the health of residents. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned technologies, the present...
