Description
Technical field
The utility model relates to supply equipment technical field, especially a kind of non-negative pressure water-supply installation flow compensation device.
Background technology
Non-negative pressure water-supply installation is applied in the secondary pressurized system of municipal water supplies, high building water more and more widely, this equipment has steady flow compensator, negative pressure inhibition device, water pump, valve, pipe fitting, sensor, electrical control system usually, and its most important function is normal water supply while, ensure that steady flow compensator does not form a negative pressure state; Full-closed structure, does not contact with air, does not have secondary pollution.
Although current non-negative pressure water-supply installation can meet conventional water supply requirement; but existing all devices does not possess flow-compensated function on the market; when city planting ductwork hydraulic pressure is in the threshold of low voltage closing setting; equipment is by frequent starting; the normal water supply that impact is overall on the one hand; add the abrasion condition of water pump simultaneously, have a strong impact on the application life of equipment.
Utility model content
In order to overcome existing non-negative pressure water-supply installation frequent starting, impact is supplied water, and damage large, the deficiency that application life is short, the utility model provides a kind of non-negative pressure water-supply installation flow compensation device.
The utility model solves the technical scheme that its technical problem adopts: a kind of non-negative pressure water-supply installation flow compensation device, comprise steady flow compensator and pipeline frame, pipeline frame is connected to the front portion of steady flow compensator, steady flow compensator is provided with flow compensator, and pipeline frame is provided with water pump, pressure sensor and pressure meter.
According to another embodiment of the present utility model, the two ends comprising flow compensator are further connected with steady flow compensator and pipeline frame respectively by bypass pipe.
According to another embodiment of the present utility model, comprising water pump further has two, is parallelly connected on two arms of pipeline frame.
According to another embodiment of the present utility model, comprise pressure sensor further and pressure meter is arranged on the house steward of pipeline frame side by side.
According to another embodiment of the present utility model, the two ends comprising flow compensator and water pump further are all provided with Hand-operated butterfly valve.
The beneficial effects of the utility model are; the basis of original non-negative pressure water-supply installation increases a set of flow-compensated system; by such improvement; when city planting ductwork hydraulic pressure is in the threshold of low voltage closing setting; while equipment supplies water, some water will compensate in steady flow compensator, prevent steady flow compensator Pressure Drop to shutting down settings; avoid the frequent starting of equipment, ensure the normal water supply of equipment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. steady flow compensator, 2. Hand-operated butterfly valve, 3. flow compensator, 4. water pump, 5. pressure sensor, 6. pressure meter in figure, 7. pipeline frame, 8. bypass pipe.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of non-negative pressure water-supply installation flow compensation device, comprise steady flow compensator 1 and pipeline frame 7, pipeline frame 7 is connected to the front portion of steady flow compensator 1, steady flow compensator 1 is provided with flow compensator 3, and pipeline frame 7 is provided with water pump 4, pressure sensor 5 and pressure meter 6.The two ends of flow compensator 3 are connected with steady flow compensator 1 and pipeline frame 7 respectively by bypass pipe 8.Water pump 4 has two, is parallelly connected on two arms of pipeline frame 7.Pressure sensor 5 and pressure meter 6 are arranged on the house steward of pipeline frame 7 side by side.The two ends of flow compensator 3 and water pump 4 are all provided with Hand-operated butterfly valve 2.
The basis of original non-negative pressure water-supply installation increases a set of flow-compensated system; by such improvement; when city planting ductwork hydraulic pressure is in the threshold of low voltage closing setting; while equipment supplies water; some water will compensate in steady flow compensator 1; preventing the Pressure Drop of steady flow compensator 1 to shutting down settings, avoiding the frequent starting of equipment, ensure the normal water supply of equipment.
Its operating principle is: tap water enters in steady flow compensator 1, sometimes municipal water pressure is very low, and the water yield is few, and water pump 4 one is opened, water in steady flow compensator 1 will soon be taken out, this time, water pump 4 just must stopped, after being provided with this device, while water pump 4 draws water, a part of water can reflux in steady flow compensator 1 by flow compensator 3, ensure that the water yield in steady flow compensator 1 meets instructions for use, water pump 4 would not frequently stop starting, and ensure that normal water supply.
Water pump 4 is as pressurized equipment, be connected with steady flow compensator 1 by pipeline, water pressurization in steady flow compensator 1 can be delivered to user place, Hand-operated butterfly valve 2 plays and controls current on-off action, is normally open under normal circumstances, pressure sensor 5 can monitor the delivery port pressure data of water pump 4, and there is transporting function, pressure meter 6, for monitoring the delivery port pressure data of water pump 4, shows on the spot, flow compensator 3 is connected with steady flow compensator 1, plays low discharge compensating action.
