Abstract
The utility model discloses a flow and pressure integrated water supply control system, connected in the water supply pipe network tube. The utility model comprises a pressurization water pump, a check valve, a pressure tank and a flow switch. The flow outlet of the pressurization water pump is connected with the flow switch after the check valve, a pressure tank is merged between the check valve and the flow switch, and a pressure switch is arranged inside the pressure tank. The system can prevent the pressurization water pump from frequently starting and stopping resulted from the pressure change in the water supply pipe network, and can enlarge the scope of application of the flow control pressurization system.
Description
Technical field
The utility model relates to a kind of hot water water management system, especially a kind of hot water water management system that adopts pressure and flow control methods.
Background technology
Hot water supply system need be installed pressure charging system mostly, and hot water supercharging mode commonly used at present has pressure controling mode, flow control mode, VFC mode.Pressure control pressure charging system changes the start and stop of controlling booster water pump according to the pipe network internal pressure, consider the difficult compressibility of liquid, during user's water, the booster water pump start and stop are frequent, thereby it is very fast that the pipe network internal pressure is changed, and the heat hydraulic pressure is unstable and influence user's normal use.The flow-control pressure charging system is controlled the start and stop of booster water pump according to the changes in flow rate in the pipe network, orders about water pump operation then because whom this kind control mode requires in the pipe network flow earlier, so require the boiler must be above water supply point.The layout of water tank generally need be considered multiple factor, especially structure load-bearing, and this has often limited applying of flow-control pressure charging system.VFC pressure charging system pressure of supply water is stable, have some water units of scale slightly to adopt this kind pressurization control mode mostly, but VFC pressure charging system cost is than higher, so that small-sized water unit uses is less.
Summary of the invention
The utility model is that a kind of flow and the integrated water management system of pressure will be provided, and this system can prevent to cause the booster water pump start and stop frequent because of the water supply network internal pressure changes; And can enlarge the scope of application of flow-control pressure charging system.
For achieving the above object, the technical scheme that the utility model adopted is; The integrated water management system of a kind of flow and pressure is connected in the feed pipe webmaster, and it comprises booster water pump, check-valves, pressurized tank, flow switch.Booster water pump flow outlet connection traffic switch behind check-valves, between check-valves and the flow switch and connect a pressurized tank, pressurized tank is built-in with pressure switch.
The utility model is owing to adopt hot water pressurization control mode, pressure and two bursts of signal Parallel Control of flow booster water pump.When the user opens with water spot use hot water, pressure in the pipe network changes, pressure signal orders about the booster water pump operation, when the user continues water, flow signal orders about the booster water pump operation equally, make the booster water pump start and stop frequent because of the pipe network internal pressure changes when having eliminated user's water, and cause hot water or cold water's pressure transient.And can enlarge the scope of application of flow-control pressure charging system again.
Description of drawings
Fig. 1 is a connection diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the integrated water management system of a kind of flow and pressure, by booster water pump 1, check-valves 2, pressurized tank 4, flow switch 3 is formed, and be connected in the feed pipe webmaster, wherein the outlet of booster water pump 1 flow connects check-valves 2, and then connection traffic switch 3, between check-valves 2 and the flow switch 3 and connect a pressurized tank 4, pressurized tank 4 is built-in with pressure switch.
Flow, the integrated control of pressure realize pressure and two bursts of signal Parallel Control of flow booster water pump.When the user opened with water spot use hot water, the pressure in the pipe network changed, and the pressure switches in the pressurized tank 4 are sent pressure signal and ordered about booster water pump 1 operation, can prevent to cause the booster water pump start and stop frequent because of the water supply network internal pressure changes; When the user continued water, flow switch 3 was sent flow signal and is ordered about booster water pump 1 operation equally, and can enlarge the scope of application of flow-control pressure charging system.
