Description

A kind of dual-use function water supply installation
Technical field
The utility model relates to a kind of non-negative pressure water-supply installation, the dual-purpose dual-use function water supply installation of an especially a kind of tank.
Background technology
At present, non-negative pressure water-supply installation on market is all generally on current stabilization tank deck, vacuum suppresser to be installed in advance, city planting ductwork water enters steady-flow tank through pipeline, strainer and backflow preventer, be pressurized to user through steady-flow tank by water pump again, with city planting ductwork junction, electro connecting pressure gauge has been installed, it is fairly simple for Water flow-path.There is following drawback in this way of supplying water: first, when in the time that water use peak produces negative pressure, in order to protect municipal ductwork pressure, the electro connecting pressure gauge of installing with city planting ductwork junction feeds back signal to control system, now can only be by shutting down, reduce given or reducing rotating speed these three kinds of modes and realize, and these three kinds of modes are all to have sacrificed the interests of user's water as cost; The second, when at water use peak, this series products steady-flow tank city planting ductwork is communicated with, and the pressure in tank is identical all the time with the pressure of city planting ductwork, and water is again incompressible material, so it cannot play the function of the compensation of regulating and storing at all; The 3rd, in fact the vacuum suppresser being arranged on steady-flow tank is exactly an air inlet-exhaust valve, and in the time producing negative pressure, vacuum suppresser is air-breathing to ensure not produce negative pressure from air, has like this chance of polluted water and public safety hidden danger; The 4th, night, unmanned water or when water ebb, owing to not configuring vacuum tank, caused the regular start-stop of equipment, caused energy waste and equipment fragile.
Utility model content
The purpose of this utility model is to provide a kind of can carry out flow-compensated and dual-use function water supply installation pressure voltage stabilizing.
In order to solve the problems of the technologies described above, the utility model dual-use function water supply installation, comprises steady-flow tank, voltage stabilization and current stabilization tank, intake pressure sensor, discharge pressure sensor, low-pressure end motor operated valve, high-pressure side motor operated valve and Intelligent control cabinet; Wherein
Described steady-flow tank two ends are connected with city planting ductwork and water inlet distribution pipeline respectively, and described voltage stabilization and current stabilization tank one end is connected with described water inlet distribution pipeline by described low-pressure end motor operated valve, and the other end is connected by described high-pressure side motor operated valve and the water outlet pipeline that confluxes;
Described intake pressure sensor, described discharge pressure sensor, be arranged on described water inlet distribution pipeline and described water outlet respectively and conflux on pipeline, with described Intelligent control cabinet communication.
Described dual-use function water supply installation also comprises freq uency conversion supercharging pump, and described freq uency conversion supercharging pump is connected with described Intelligent control cabinet, described low-pressure end motor operated valve and described high-pressure side motor operated valve respectively.
The utility model dual-use function water supply installation can continue water yield compensation to city planting ductwork automatically, " the lack of water negative pressure " having produced while having avoided pipe network ability to be less than by discharge, can also play to user's pipe network the effect of stabilizing compensation, reduce freq uency conversion supercharging priming of pump number of times, controlled because " transient flow negative pressure " produces the potential safety hazards such as air bag, vapour lock, pressure oscillation, refluence and water hammer simultaneously, ensure the safety and the comfortableness that supply water, reached good energy-saving effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model dual-use function water supply installation is described in detail.
As shown in Figure 1, the utility model dual-use function water supply installation, comprise intake pressure sensor 1, steady-flow tank 2, water inlet distribution pipeline 3, freq uency conversion supercharging pump 4, low-pressure end motor operated valve 5, voltage stabilization and current stabilization tank 6, high-pressure side motor operated valve 7, the water outlet pipeline 8 that confluxes, discharge pressure sensor 9 and Intelligent control cabinet 10, steady-flow tank 2 two ends are connected with city planting ductwork A and water inlet distribution pipeline 3 respectively, voltage stabilization and current stabilization tank 6 one end are connected 3 by low-pressure end motor operated valve 5 with water inlet distribution pipeline, the other end is connected by high-pressure side motor operated valve 7 and the water outlet pipeline 8 that confluxes, intake pressure sensor 1, discharge pressure sensor 9, be arranged on respectively into water distribution pipeline 3 and water outlet and conflux on pipeline 8.Intake pressure sensor 1 and discharge pressure sensor 9, be transported to Intelligent control cabinet 10 the force value monitoring in signal of telecommunication mode.The valve of opening of low-pressure end motor operated valve 5 and high-pressure side motor operated valve 7 is by Intelligent control cabinet 10 with closing valve events.
In actual applications, in the time of device start, intake pressure sensor and discharge pressure sensor moment monitoring municipal ductwork pressure situation, according to local city planting ductwork requirement, set the lower safety limit value of a ductwork pressure.Under normal circumstances, the inlet pressure of equipment is all higher than the lower safety limit of city planting ductwork, now, low-pressure end motor operated valve is in closing valve state, high-pressure side motor operated valve is in opening valve state, and voltage stabilization and current stabilization tank is in energy storage state, and equipment makes full use of ductwork pressure, freq uency conversion supercharging, lacks how many benefit and how much keeps outlet pressures stable.When intake pressure Sensor monitoring is to municipal ductwork pressure during close to network security lower limit, intake pressure sensor can send instruction to Intelligent control cabinet in time, in time low-pressure end motor operated valve is opened, high-pressure side motor operated valve cuts out, in voltage stabilization and current stabilization tank, water flows out and carries out flow-compensatedly, has stopped the flow condition that " lack of water negative pressure " produces.When user's water ebb or night are when unmanned water, low-pressure end motor operated valve is in closing valve state, high-pressure side motor operated valve is in opening valve state, freq uency conversion supercharging pump is in the state of quitting work, voltage stabilization and current stabilization tank flow direction median user pipe network, compensate, play the effect of stablizing user's ductwork pressure, reached good energy-saving effect.
The utility model dual-use function water supply installation can continue water yield compensation to city planting ductwork automatically, " the lack of water negative pressure " having produced while having avoided pipe network ability to be less than by discharge, can also play to user's pipe network the effect of stabilizing compensation, reduce freq uency conversion supercharging priming of pump number of times, controlled because " transient flow negative pressure " produces the potential safety hazards such as air bag, vapour lock, pressure oscillation, refluence and water hammer simultaneously, ensure the safety and the comfortableness that supply water, reached good energy-saving effect.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
