Abstract
The utility model discloses an enclosed frequency variable non-negative pressure water supply device, which comprises a flux buffer tank, wherein the water inlet orifice of the flux buffer tank is connected with a tap water pipe and the water outlet orifice is connected with a user water pipe via a water pump water supply pipeline; the flux buffer tank has a baffle plate for dividing the tank into a water storage chamber and an energy storage chamber; the baffle plate is provided with a pressure control valve communicating the water storage chamber and the energy storage chamber; the water outlet orifice is mounted at the bottom of the water storage chamber; an energy storage water pipe is provided between the energy storage chamber and the user water pipe and is provided with an intelligent pressure adjuster; the user water pipe is connected with a remote pressure sensor serially; the remote pressure sensor and the pressure adjustment controller are electrically connected with an electric control box. The enclosed frequency variable non-negative pressure water supply device can continuously supply water to users, to resolve the defects of prior art whose water pump is started and stopped frequently, to cause pressure fluctuation of water supply.
Description
Technical field
The utility model relates to the supply equipment field, specifically is a kind of totally-enclosed frequency conversion non-negative pressure water-supply installation that is used for the water supply pipe system.
Background technology
At present, supplying water in the urban skyscraper, what mostly adopt is that water tank and variable frequency pump supply water, and there are shortcomings such as waste energy, floor space are big in this way of supplying water.The non-negative pressure water-supply installation that adopts on the market directly is connected with water supply pipe now, flow surge tank and variable frequency pump that employing has outlet valve supply water to the user, when working, this equipment work can produce certain influence to the intake pressure of running water pipe, and the frequent starting of water pump and stop to cause the instability of hydraulic pressure, influence user's water demand.
The utility model content
The technical problems to be solved in the utility model provides a kind of totally-enclosed frequency conversion non-negative pressure water-supply installation that can guarantee the user side pressure stability.
For solving the problems of the technologies described above, the totally-enclosed frequency conversion non-negative pressure water-supply installation that is provided, comprise the flow surge tank, the water inlet pipe mouth of flow surge tank is connected with running water pipe, the effluent pipe mouth of flow surge tank is connected with service pipe by water pump feed pipe group, its design feature is: be provided with dividing plate in the described flow surge tank it is divided into water storage cavity and energy-storing chamber, dividing plate is provided with the pressure-control valve that is communicated with water storage cavity and energy-storing chamber, described effluent pipe mouth is installed in the bottom of water storage cavity, be provided with the energy storage water pipe between described energy-storing chamber and the service pipe, the energy storage water pipe is provided with the intelligent pressure adjuster, distal pressure sensor is installed on the service pipe, and distal pressure sensor and intelligent pressure adjuster all are electrically connected with electric control box.
After adopting said structure, dividing plate in the flow surge tank is divided into water storage cavity and energy-storing chamber two parts with it, dividing plate is provided with the pressure-control valve that is communicated with water storage cavity and energy-storing chamber, effluent pipe mouth is installed on the water storage cavity, be provided with the energy storage water pipe between energy-storing chamber and the service pipe, the energy storage water pipe is provided with the intelligent pressure adjuster.When normal water supply, pressure-control valve cuts out, and adds the water of certain pressure by the energy storage water pipe in energy-storing chamber, and when reaching certain pressure in the energy-storing chamber, electric control box is closed the intelligent pressure adjuster, and energy storage this moment water pipe is in closed condition; When the service pipe upward pressure was too small, pressure is also corresponding in the water storage cavity reduced, and the pressure-control valve on the dividing plate is opened automatically, and supplementing water is used for satisfying pressure demand to water storage cavity from energy-storing chamber, thereby has protected original pressure of pipe network; The utility model can uninterruptedly supply water to the user, has remedied prior art water pump frequent start-stop, pressure of supply water deficiency fluctuated.
Described water pump feed pipe group comprises two groups of water pumps in parallel and the flap valve that is connected in series with water pump, the in addition bypass branch road in parallel with described water pump, and the bypass branch road is provided with flap valve.
