Description

Circulating water supply system for multi-storey building

Technical Field

The utility model relates to a system water treatment field such as straight drinking water, pure water, nanofiltration, ultrafiltration specifically is a multi-storey building circulation water supply system.

Background

At present, the multi-storey buildings (buildings with 6 storeys or less than 20 meters) of most cities in China have two common water supply modes: the direct water supply mode is that the pressure of the municipal pipe network is directly utilized to directly supply water to each water consumption point of the indoor pipe network, the water supply scheme has good economic performance and does not need any other equipment or measures, and the defects that the water quantity and the water pressure can not be ensured at the peak water consumption period, and the normal water consumption of users is influenced; and the other is a secondary pressurizing water supply mode of a water storage tank and a pressure stabilizing pump set, namely, water is supplied to the water storage tank by a municipal pipe network, and water in the water storage tank is pumped to each water using point of an indoor pipe network by the pressure stabilizing pump set. The water supply mode is safe and reliable, but the energy consumption is high, the pressure utilization rate of a municipal pipe network is zero, and energy is seriously wasted.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a multi-storey building circulation water supply system to the water peak time water pressure water yield is not up to standard and the higher problem of energy consumption under secondary pressure boost water supply mode under the direct water supply mode that provides in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a multi-story building circulating water supply system comprising:

the water purification unit, water purification unit one end flange joint has the inlet tube, is located the one end flange joint that the inlet tube was kept away from to the water purification unit has the water tank, is located water tank other end flange joint has the working shaft, just working shaft flange joint has the check valve, check valve flange joint has the delivery pipe.

As a further aspect of the present invention, the water supply pipe flange is connected to a plurality of water consumption points.

As a further proposal of the utility model, a pressure reducing valve is arranged on the water supply pipe.

As a further scheme of the utility model, be located the delivery pipe is kept away from the one end flange joint who uses the water spot has the wet return with water tank flange joint, and is located install circulation flow control valve on the wet return.

As a further proposal of the utility model, the water return pipe is provided with a disinfection device near the water tank.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses concentrate optimization direct water supply mode and secondary pressure boost water supply mode, arrange delivery pipe and wet return on the same journey, each loop resistance loss is close, can prevent the short circuit phenomenon that circulates, improves water supply efficiency, and the energy loss is low, easy operation, the construction degree of difficulty is low.
