Description
Technical field
The utility model relates to pipe network tap water supply equipment technical field, refers to especially a kind of non-negative pressure water-supply installation.
Background technology
Growing along with modernized society, tap water supply more and more can not be hidden the present water supply requirement of foot and the demand of highrise building water, the growing tension of water resource from.Also has the shortage of the security control of the pipe network to second pressure water supply.
At present, many secondary water-supply equipment all takes water tank or pond to add that constant pressure water supply equipment forms, but the complete like this quality that can not ensure secondary water-supply water.Original clean hygiene is placed in pond or water tank with the tap water of virus killing, chlorine residue in water is decomposed rapidly, various foreign material enter water tank or pond, severe contamination water source, contaminated water is supplied with resident family by secondary pressurized equipment and is drunk, extremely threaten the healthy of resident family, also have and cleaning water tank and the water resource waste in pond and the waste of human input.Also have the later stage maintenance of pond or water tank to can not be guaranteed to user's timely water.
In city, existing non-negative pressure water-supply installation has adopted the airtight steady-flow tank with air bag, inflates in advance, pours water, and has played the effect of the amount of makeup water in short time in the time of water supply gets.Equipment is all adopting the size of selecting steady-flow tank in secondary water-supply lectotype selection specification aspect type selecting, but because the capsule of installing in tank or air bag have occupied most volume of tank body, tank inner storing water amount does not reach design completely and wants, also vacuum inhibitory control parts on tank body in addition, can not ensure that the water in tank body supplements away the water demand for user, the remission time can not fully reach short water supply time completely.Also have to adopt and fill in advance two chambeies of gases at high pressure or the mode of multi-cavity tonifying Qi, in the course of time gas water-soluble or taken away by water after there will be the phenomenon that can mend without gas, so just can not eliminate vacuum and negative pressure appearance.
Existing equipment, for the requirement that meets user's pressure-stabilizing water supply adopts the mode collection signals such as the simple control of constant pressure valve or distance-transmission pressure gauge, pressure sensor to feed back to frequency converter to regulate the rotating speed control of water pump in pressurization outlet, do not consider completely at user's pipe network and can not resist high pressure and produce danger and security control mode during at user's pipe burst.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment: referring to Fig. 1, a kind of non-negative pressure water-supply installation, comprise tap water city planting ductwork 1 and on successively connect inlet valve 2, motor operated valve 4 and steady-flow tank 7; Steady-flow tank 7 is connected with water pump 15, vacuum tank 11 and pressure sensor 12 by pump group water intaking valve 13, on steady-flow tank 7, be also connected with the automatic computer constant pressure frequency conversion switch board 10 of a control motor operated valve 4, on city planting ductwork 1, be also provided with strainer 3 and backflow preventer 5, steady-flow tank 7 is provided with the mechanical negative pressure inhibition device 6 of a mechanical tonifying Qi, exhaust, and adopt control line to connect the low water level controller 9 of automatic computer constant pressure frequency conversion switch board 10, also comprise the water outlet main valve 16 that connects user 19.
As preferably, described steady-flow tank 7 belows are also provided with blowoff valve 8 and negative pressure early warning controller 17, and negative pressure early warning controller 17 also adopts control line to connect automatic computer constant pressure frequency conversion switch board 10.
As preferably, on outlet pipeline, be provided with the high-low pressure alarm controller 18 of controlling water pump 15 and reporting to the police, and high-low pressure alarm controller 18 adopts control line to connect automatic computer frequency conversion and unvarying pressure control cabinet.
Pipe network tap water enters steady-flow tank 7 by water inlet main valve, strainer 3, motor operated valve 4, backflow preventer 5, now strainer 3 filters the foreign material in water, ensure user 19 the use water hygiene, there is no foreign material to enter the pump housing to have extended like this application life of equipment, steady-flow tank 7 totally-encloseds are provided with blowoff valve 8, low water level controller 9 and mechanical negative pressure inhibition device 6, negative pressure early warning controller 17, water enters steady-flow tank 7, and the air in tank is got rid of in mechanical negative pressure inhibition device 6 actions.
Automatic computer constant pressure frequency conversion switch board 10 detects when water enters water pump 15 and user's 19 water demand, automatic computer constant pressure frequency conversion switch board 10 starts variable frequency starting water pump 15 successively, and the pressure sensor 12 of installing on user's 19 pipe networks detects that pressure signal feeds back to automatic computer constant pressure frequency conversion switch board 10.When automatic computer constant pressure frequency conversion switch board 10 obtains pressure and reaches requiring of user 19, instruction water pump 15 reduces speed now and enters dormancy.In the time that user 19 has a small amount of water, user's 19 ductwork pressures slowly decline and carry out supply by the vacuum tank 11 being located on user's 19 pipe networks, in the time that vacuum tank 11 can not meet user 19 and requires, automatic computer constant pressure frequency conversion switch board 10 instruction water pump 15 start and stop again, the like.
At tap water during to peak special circumstances in short supply, motor operated valve 4, backflow preventer 5, negative pressure early warning controller 17, mechanical negative pressure inhibition device 6, low water level sensor move comprehensively, ensure like this safety of tap water pipe network, stopped the generation of vacuum and negative pressure.
When in layman's use with at user's 19 pipe burst in the situation that, the utility model detects that at the high-low pressure alarm controller 18 of user's 19 pipe Net-based Designs high pressure or low-voltage signal feed back to automatic computer constant pressure frequency conversion switch board 10 instruction water pumps 15 and enter resting state and report to the police.Can avoid like this in the time of high pressure, destroying user's 19 pipe networks, avoid the waste overflowing by pipe network tap water and flooded bad user 19 article and house facility.
In the time that tap water pressure meets user's 19 water requirement, tap water directly supplies water for user 19 by bypass pipe, and pump group, completely in resting state, is used electrical zero loss.
When power failure, the automatic save data of automatic computer constant pressure frequency conversion switch board 10, and record power off time, and tap water directly supplies water to user 19 by bypass, and when incoming call, automatic computer constant pressure frequency conversion switch board 10 resumes water supply automatically.
To sum up the utility model is the most stable a kind of, safety, intelligent high full-automatic non-negative pressure constant pressure frequency conversion supply equipment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
