Double-protection safety energy-saving secondary water supply device

Abstract

The invention discloses a double-protection safety energy-saving secondary water supply device which is connected with a municipal water supply pipe network. The double-protection safety energy-saving secondary water supply device is sequentially provided with a butterfly valve, a filter, a backflow checker, a pressure gage, a pressure sensor, a high-speed water source switcher, an ultraviolet sterilizer, a double-cavity steady flow tank, a butterfly valve, a flexible connection, a water pump, a flexible connection and a check valve and a butterfly valve outputting to a residential water pipe network. A branch water pipe is arranged on a water supply pipe, the branch water pipe is provided with a butterfly valve, a water tank and a high-speed water source switcher and then connected with another loop, and a liquid level sensor, a vacuum suppresser, a manhole, an overflow pipe and a butterfly valve are arranged in the water tank. The double-protection safety energy-saving secondary water supply device has the advantages of being small in investment, simple to install, convenient to operate, energy-saving and safe and healthy in water supply and simultaneously solves the problem that no water can be used by users when water supply is cut off or water pressure of the municipal pipe network is small.

Description

technical field [0001] The invention relates to a water supply equipment, more specifically to a secondary water supply equipment with double guarantees, safety and energy saving. Background technique [0002] Since 2002 in my country, more than 90% of the residential buildings in first-tier cities are high-rise buildings (16-32 floors), and there are fewer buildings below 16 floors, and the state strictly prohibits residential buildings below 6 floors. The number of high-rise buildings in second- and third-tier cities is also increasing year by year. Usually, the pressure provided by the municipal tap water is generally 0.3Mpa, which can only satisfy the users below the 6th floor, and the users above the 6th floor must pressurize through the secondary water supply equipment to reach the pressure required by the user. [0003] The emergence of secondary water supply equipment has solved the above problems, but a large amount of information shows that with the development of...
