Description
Technical Field
The utility model belongs to the water treatment field, concretely relates to water supply network protection device.
Background
In the urban water supply process, water is supplied to high buildings or high lands, the delivery pressure of tap water is not enough to convey water to the high lands, a secondary water supply pipeline is connected to a water supply pipeline network to carry out pressurization relay water supply, and the mode has some problems in water supply at present.
On continuously supplying water, although many secondary water supply lines possess the function of preventing negative pressure, but mostly will stop supplying water after monitoring that water supply network pressure is low and is crossed the setting value, water supply network's pressure can not reduce to zero, but the pressure reduction that lasts still can influence water supply network and supply water. In addition, because of the high and low peak periods of the water consumption of the user, the water pressure in the water supply pipe network can change in a fluctuating manner, and the water supply of the water supply pipe network is also influenced.
In terms of water supply safety, a traditional secondary water supply pipeline generally adopts the mode that a check valve or a water hammer eliminator is additionally arranged at the rear end of a lifting pump to prevent the damage of a water hammer to equipment and the pipeline caused by high-level water backflow, the water hammer risk caused by the leakage and even the damage of the check valve and the water hammer eliminator is difficult to detect until serious faults such as pipe explosion and the like cause a great amount of property loss; simultaneously, in complicated water supply network, the condition that the pipeline bursts can appear in some cases unavoidably, especially some bury in the underground, the hydraulic pipeline of difficult by people's discovery, after the problem appearing, people only wait to appear cutting off the water supply usually, or discover to leak by a large scale and just can handle, not only influence the user and use, also can cause a large amount of wasting of resources.
Therefore, it is necessary to monitor and control the water pressure of the secondary water supply pipeline and the water supply network.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's is not enough, provide one kind can the initiative adjust the water supply network water delivery capacity and the water supply network protection device of the initiative monitoring secondary supply channel condition.
The utility model provides a technical scheme that its technical problem adopted: supply network protection device, including the water intake pipe, the control pipeline, emergent pipeline, outlet pipe way and control box, the control pipeline communicates water intake pipe and outlet pipe way respectively, emergent pipeline communicates water intake pipe and outlet pipe way respectively, be equipped with manual valve I on the control pipeline in proper order, water flow sensor, pressure sensor I, electrical control valve, the check valve, pressure sensor II and manual valve II, be equipped with manual valve III on the emergent pipeline, water flow sensor, pressure sensor I, electrical control valve and pressure sensor II are connected with the control box, the switching of control box control electrical control valve, the control box is equipped with the alarm lamp.
Preferably, the pressure sensor I and the pressure sensor II are pressure transmitters or electric contact pressure gauges.
Preferably, the water flow sensor is an electromagnetic flow meter or a turbine flow meter.
The utility model discloses operational mode and principle: before the device runs, the manual valve I and the manual valve II are opened, and the manual valve III is closed; and when the device needs to be overhauled or maintained, the manual valve I and the manual valve II are closed. The manual valve III is opened to prevent the water outlet pipeline from being lack of water; when the device is operated, the minimum pressure and the minimum flow which are required to be kept by the water supply network are set through the control box; when water is used in a low valley, the water supply network supplies sufficient water, the data monitored by the pressure sensor I and the water flow sensor are larger than a set minimum value, the control box controls the electric regulating valve to be fully opened, and the water supply network supplies water fully; when a water consumption peak or pipe burst occurs, when any monitoring value of the pressure sensor I and the water flow sensor is lower than a set minimum value, the control box controls the opening degree of the electric regulating valve, the data monitored by the pressure sensor I and the water flow sensor are always kept to be larger than or equal to a set value, until a water supply pipe network cannot meet secondary water supply, the valve of the electric regulating valve is completely closed, water supply is stopped, the control box controls the operation of an alarm lamp, and the pipeline fault is early warned, so that the original pressure and flow of the water supply pipe network are utilized to the maximum extent; when check valve or water hammer annihilator trouble of secondary water supply pipeline, when the water pressure transmission in the secondary water supply pipeline was to outlet pipe, the water pressure that pressure sensor II monitored was greater than the water pressure that pressure sensor I detected, and control box control alarm lamp work, early warning pipeline trouble.
Compared with the prior art, the beneficial effects of the utility model are that:
1. through monitoring water supply network and secondary water supply pipeline simultaneously, can effectively maintain water supply network's normal water supply, prevent that secondary water supply pipeline from unusual to water supply network's influence that supplies water, guarantee the most efficient utilization of water supply network resource, reduce water supply network pressure oscillation.
2. The flow and the pressure are monitored simultaneously, troubles caused by failure faults of a single sensor are avoided, the running stability of the device is improved, and meanwhile, the control precision is also greatly improved.
