Non negative-pressure water supply system of high position water-storing tank

Abstract

The invention provides a non negative pressure water supply system with a high-position water storage tank, which consists of a tap water inlet pipe, a backflow preventer, a steady flow compensator, a vacuum suppressor, a water pump, the high position water storage tank, a control cabinet and a user water supply pipe, wherein the tap water inlet pipe is connected with the steady flow compensator and the vacuum suppressor and then is connected with the water pump; a water pump water outlet pipe is directly connected with the user water supply pipe; the tail end of the user water supply pipe is connected with the high position water storage tank; and a water outlet pipe of the high position water storage tank is connected with a water inlet pipe thereof at the bottom part of the high position water storage tank after passing through an electric valve and a check valve. The non negative pressure water supply system can effectively ensure that the system does not influence the normal use of water for the user water supply pipe when the water pump is stopped due to water off, power failure or insufficient water inflow of the tap water inlet pipe; and the system has the advantages of reliable water supply, energy conservation in operation, good water quality, and high automation degree, and is widely applied to a secondary pressurizing water supply system of which the water inflow of the tap water inlet pipe cannot satisfy the peak water use of the user water supply pipe periodically or frequent short-term water breaks occur.

Description

1. Technical field [0001] The invention relates to a secondary pressurized water supply system, in particular to a non-negative pressure water supply system with a high-level water storage tank directly connected in series with a tap water inlet pipe for pressurization. 2. Background technology [0002] At present, the known non-negative pressure water supply system can be directly connected in series to the tap water inlet pipe and then pressurized to supply water to the user's water supply pipe. The technical non-negative pressure water supply system has defects such as small system adjustment volume and no reserve water volume. Therefore, the existing technology cannot solve the problem that the water intake of the tap water inlet pipe does not meet the peak water requirements of the user's water supply pipe or the tap water inlet pipe often Water supply problems without water. 3. Contents of the invention [0003] In order to overcome the shortcomings of the above-men...
