Description

High-rise building pipe network pressurization zone water supply device

technical field

The utility model relates to a pressurized and partitioned water supply device for a high-rise building pipe network of a municipal tap water pipe network.

Background technique

In the water supply system of high-rise buildings, municipal water supply is generally used below four floors, five to fourteen floors are divided into low areas, and above fifteen floors are high areas, and booster pump sets are used for pressurized water supply in both low areas and high areas. . At present, in the domestic water supply system of high-rise buildings with more than two partitions, if non-negative pressure water supply equipment is used, two sets of devices are often used, one for the low area system and the other for the high area system. It adopts superposition and series connection to supply water, that is, connects a high-region water supply device in series at the end of the low-region water supply pipe. This structure seems to use the water supply pressure in the low area to save energy and electricity, but the actual implementation is not a simple superposition of a technical problem. First, the calculation of the water supply flow in the low area must include the flow in the high area. ) The diameter of the pipe should be increased, the flow rate of the water pump should be increased, and the power of the water pump should also be increased, so that the equipment installed in series in the high area can meet the water supply flow requirements of the high area; in addition, the equipment in the high area will occupy an area of 8-10m ² The special-purpose room requires a lot of investment cost, the operation of the equipment is not economical, and the maintenance and maintenance are not convenient; more importantly, if the equipment in the low area fails and the water stops, the high area will be directly affected and the water will be shut down.

Contents of the invention

The purpose of the utility model is to provide a high-rise building pipe network pressurized partition water supply device with simple structure, cost saving, reliable operation and convenient pipeline.

The pressurized water supply device for the high-rise building pipe network of the utility model includes a municipal water inlet pipe, a regulating water tank, an automatic exhaust valve, an electric contact pressure gauge, an automatic air suction valve, a control cabinet, a water level controller, and a low-area booster pump group. 1. High-zone booster pump set, its characteristics are: adjust the water supply main pipe at the bottom of the water tank to connect with the suction pipe, one end of the suction pipe is installed with a high-zone booster pump set, and the other end is installed with a low-zone booster pump set, and the high-zone booster pump set is installed. The pressure pump unit and the low-area booster pump unit are connected to the user through the high-area water supply pipe and the low-area water supply pipe, respectively. The high-area water supply pipe and the low-area water supply pipe are equipped with pressure sensors, and the pressure sensors transmit pressure signals to the control cabinet. Automatically control the adjusted constant pressure; a pressurized water return pipe is installed on the water supply pipe in the low area, and the other end of the pressurized water return pipe is connected to the regulating water tank to enhance the stable water flow of the regulating water tank and maintain the continuity and resistance of the water flow. Sudden pressure changes and transient flow state, better maintain no negative pressure.

The pressurized partition water supply device of the high-rise building pipe network of the utility model cancels the bypass pipe of the municipal direct water supply. In addition to the characteristics of ordinary non-negative pressure water supply equipment, it also has the characteristics of simple control system and structure configuration, and reliable operation. Its high and low water supply is equipped with only one regulating water tank, which not only reduces the equipment cost, but also simplifies the equipment installation, and the pipeline installation and maintenance are convenient.
