Description

Double outlet partition non-negative pressure water supply equipment

1. Technical field

The utility model relates to a secondary pressurized water supply equipment, in particular to a double-outlet partition non-negative pressure water supply equipment.

2. Background technology

At present, the vertical division of the water supply system of high-rise buildings mostly adopts three methods: pressure reducing valve division, water tank decompression division and multiple sets of equipment parallel division. The pressure reducing valve division is easy to damage the pressure reducing valve, and the system has a greater safety hazard; The decompression partition of the water tank has defects such as secondary pollution of water quality, large noise of water tank falling, occupying building area, and is not conducive to structural earthquake resistance and increasing structural load of the building; when multiple sets of equipment are used in parallel partitions, the equipment investment and land occupation are relatively large. Larger, therefore, the prior art cannot well solve the vertical partition problem of the water supply system of high-rise buildings.

3. Contents of utility model

The purpose of the invention of the utility model is to provide a non-negative pressure water supply equipment with dual outlets and partitions with low investment, low energy consumption, small land occupation, safe and reliable water supply, and hygienic water quality.

The technical solution adopted by the utility model to solve the technical problem is: the double-outlet partition non-negative pressure water supply equipment is composed of a steady flow compensator, a vacuum suppressor, a low-area water pump, a high-area water pump, a control cabinet, a pressure sensor, etc. The steady flow compensator is equipped with a vacuum suppressor and a pressure sensor. The water inlet pipe of the steady flow compensator is directly connected in series with the outdoor municipal pipe network, and its outlet pipe is connected with the water suction main pipe. The main pipes are connected, and the outlet main pipes of the water pumps in the low area and the water pumps in the high area are set separately, and pressure sensors are respectively installed on the water outlet pipes. Area users, vacuum suppressors, low area water pumps, high area water pumps, and pressure sensors are connected to the control cabinet respectively.

5. Specific implementation

Below with regard to accompanying drawing 1, do following detailed description to the double outlet partition of the present utility model without negative pressure water supply equipment.

As shown in accompanying drawing 1, the dual-outlet zone-free negative pressure water supply equipment of the present utility model is composed of a steady flow compensator (1), a vacuum suppressor (4), a low zone water pump (7), and a high zone water pump (10) , control cabinet (5), pressure sensor (3) (8) (11), etc., the steady flow compensator (1) is equipped with a vacuum suppressor (4) and pressure sensor (3), and the steady flow compensator (1) The water inlet pipe (2) is directly connected in series with the outdoor municipal pipe network, and its outlet pipe is connected to the main water suction pipe (6). Connected, the water outlet main pipes (9) (12) of the low area water pump (7) and the high area water pump (10) are set separately, and pressure sensors (8) (11) are respectively installed on the water outlet main pipes (9) (12) ), wherein the water outlet main pipe (9) of the low area water pump (7) is for the low area user (13), the water outlet main pipe (12) of the high area water pump (10) is for the high area user (14), the vacuum suppressor (4), The low zone water pump (7), the high zone water pump (10), and the pressure sensor (3) (8) (11) are connected to the control cabinet respectively.

The dual-outlet partition non-negative pressure water supply equipment of the utility model adopts the low-region water pump and the high-region water pump to pressurize the partition water supply, and shares the steady flow compensator, vacuum suppressor and water suction main pipe, etc., to realize the non-negative pressure water supply. Compared with the existing technology, it has the characteristics of low investment, low energy consumption, small land occupation, safe and reliable water supply, and hygienic water quality, and is widely applicable to secondary pressurized water supply occasions in high-rise building water supply system divisions.
