Description

Non-negative pressure pipe direct drinking water supply system

1. Technical field

The utility model relates to a pipeline direct drinking water pressurized water supply system, in particular to a non-negative pressure pipeline direct drinking water supply system.

2. Background technology

Most of the piped drinking water supply systems of existing high-rise buildings use independent piped drinking water treatment stations, which need to set up independent direct drinking water machine rooms and direct drinking water treatment equipment. The equipment occupies a large area, maintenance operations are troublesome, and the initial investment cost is high. There are also some residential quarters that use centralized or regional pipeline direct drinking water supply water supply systems. However, due to the different heights and zoning conditions of various buildings, there are phenomena such as high pressure on the user pipe network in low areas or waste of decompression energy. At the same time, centralized or regional pipelines are used to supply direct drinking water. The water supply system has a long pipeline, and it is difficult to guarantee the water quality of end users.

3. Contents of utility model

In view of the above-mentioned deficiencies in the prior art, the utility model provides a non-negative pressure pipe direct drinking water supply system with reasonable design, simple structure, small footprint, low investment, convenient operation and maintenance, and can be directly connected in series to the direct drinking water supply pipe network. system.

The technical solution adopted by the utility model to solve its technical problems is: the non-negative pressure pipeline direct drinking water supply system is composed of a steady flow compensator, a vacuum suppressor, an ultraviolet sterilizer, a water pump, an electromagnetic valve and a control cabinet, and the direct drinking water supply pipeline Connect the backflow preventer, steady flow compensator, ultraviolet sterilizer, and water pump in turn to the user's water supply pipe network, and set up the user's return water pipe network on the same journey as the user's water supply pipe network, and connect the user's return water pipe network to the direct drinking water supply pipe After the backflow preventer, a solenoid valve and a check valve are installed on the user's return water pipe network, a vacuum suppressor and an inlet water pressure sensor are installed on the steady flow water replenisher, and a water supply pressure sensor is installed on the user's water supply pipe network behind the water pump. Sensors, vacuum suppressors, ultraviolet sterilizers, water pumps, solenoid valves, water inlet pressure sensors and water supply pressure sensors are wired to the control cabinet respectively.

Vacuum suppressor and steady flow compensator realize the direct series connection between the water pump and the direct drinking water supply pipeline without generating negative pressure. There is no need to install an intermediate water tank when the pump is pressurized, which can not only utilize the available pressure on the direct drinking water supply pipeline, but also save energy consumption, and avoid the pollution of the intermediate tank.

The beneficial effect of the utility model is that, while the water pump is directly connected in series with the direct drinking water supply pipeline for pressurization by adopting the steady flow compensator and the vacuum suppression, a user return water pipe network is set at the same distance as the user water supply pipe network, which effectively guarantees direct drinking water supply. The drinking water in the user's water supply network is fresh and hygienic, and the system is simple, flexible in setting, small in land occupation, low in investment, energy-saving in operation, and convenient in installation and maintenance.
