Abstract
The utility model belongs to the technical field of construction work, as an improvement of the existing air-pressure water supply device. The utility model is characterized in that an automatic water-diverting apparatus and an automatic air supply apparatus are connected in series between a water-diverting pipe and a No. 1 water pump; an electromagnetic valve is connected in series in front of the automatic air supply apparatus; a hole is drilled on the valve plate of a check valve of a No. 2 water pump. The utility model thoroughly overcomes the defect of water leakage or non diversion of the water-diverting pipe.
Description
The utility model belongs to construction engineering technical field, particularly relates to a kind of improvement of pressure watering device.
The applicant obtains " a kind of pressurized-type water supply unit " (applying date: on November 27th, 85 of utility model patent on November 6th, 1987, patent No. ZL85205098 number) in, once proposing a kind of at domestic existing waterpower gas compensating type water supply installation is technical characterictic with " automatic drain valve is set on adjutage ", and has the design scheme of advantages such as automatic water supplement, gas-water separation.
Yet, practice more than a year shows, just at single pump operation or in 24 hours during continuous water supply, operational effect is more satisfactory and reliable, and replaces linkage operation at two pumps for this scheme, perhaps when a pump list pump operation, if a pump termination of pumping time is longer, because the automatic water supplement amount is limited, even leaking on a small quantity appears in bottom valve, the water level of a water pump outlet pipe also can drop to along with the continuity of the time of leaking below the impeller of water pump, causes water pump to produce cavitation.At this moment in the time of a pump will occurring and start once more, aqueduct does not draw the defective of water.
In order to overcome above-mentioned defective, the applicant proposes the application's design scheme again on the basis of ZL85205098 patented product.
Accompanying drawing is a composition schematic diagram of the present utility model, among the figure 1 is underground storage tank, 2 is the aqueduct of automatic scuttlebutt, and 3 is automatic scuttlebutt, and 4 is the suction water pipe of a centrifugal water pump, 6 is a centrifugal water pump, 6 is flow pipe, and 7 is automatic air compensation device, and 8 is automatic air compensating valve, 9 is electromagnetic valve, 10 is flap valve, and 11 is air pressure tank, and 12 is a pressure controller, 13 is No. two pressure controllers, 14 is water supply network, and 15 is the aqueduct of No. two centrifugal water pumps, and 16 is No. two centrifugal water pumps, 17 is flap valve, and 18 is flow pipe.
Substance of the present utility model is to utilize to the automatic ration tonifying Qi of automatic inflating device device with to the automatic water supplement of automatic water-leading device, solves aqueduct and leaks or do not draw water problem. Specific embodiments is:
1, between aqueduct 2 and water pump 5, connect one the automatic scuttlebutt 3 of becoming one and air compensation device 7 automatically.
2, at electromagnetic valve 9 of the front of automatic air compensating valve 8 series connection, the dual-use function that makes it have automatic tonifying Qi simultaneously and control air compensation automatically.
3, on the valve plate of No. two pump flap valve 17, bore the moisturizing hole of 1～3 millimeter of a φ, it is had simultaneously prevent the backwater adverse current and to the dual-use function of automatic scuttlebutt 3 automatic water supplements.
The utility model can carry out the linkage operation that two pumps replace as required, or carries out single pump running.With the example that operates as of a water pump 5, its water supply process is as follows: at first will fill diversion in the automatic scuttlebutt 3, the electric contact of a pressure controller 12 is adjusted to minimum running pressure P 1 and the highest running pressure P 2 parts again.Then start water pump 5 No. one, send water to building pipe network and air pressure tank 11, and air is mended in the air pressure tank 11.Simultaneously, enter the air in the water yield compressed tanks in the air pressure tank 11, jar interior pressure is constantly increased.When reaching maximum pressure P2, No. one pressure controller 12 is handled water pump 5 automatic stoppings.Continue water as the user, the air pressure in the air pressure tank 11 can be given pipe network with water.When the air pressure in the jar dropped to minimum running pressure P 1 gradually, a pressure controller was handled a water pump 5 again and is started running.Make running continue to carry out so repeatedly.A water pump 5 as running breaks down, and electrical control cubicles automaticallyes switch, and a pump is stopped, and starts No. two pumps 16 and remain in operation.
In pump 5 later delay time out of service a second to a minute, electromagnetic valve 9 cuts out automatically, makes automatic air compensating valve 8 stop tonifying Qi.This timing, quantitative tonifying Qi measure have intermittently overcome because the aqueduct drainage that the tonifying Qi overlong time of automatic air compensation device occurs.Simultaneously, when a pump shuts down, water in the flow pipe 18 of No. two pumps 16, constantly enter automatic scuttlebutt by the boring on the flap valve valve plate, make the water level of automatic scuttlebutt keep stable, thereby overcome when automatically the drawdown of scuttlebutt causes that a pump starts once more, aqueduct does not draw the phenomenon of water.
Major advantage of the present utility model is: both merged the various advantages of existing product, fundamentally overcome the defective that aqueduct that existing product exists leaks or do not draw water again, and saved the water-bed valve on the aqueduct.
Embodiment: the applicant has designed one group of one jar of two pump vacuum quantitative gas compensating type pressure watering device that is used for underground storage tank for certain unit.Major parameter is: aqueduct and pipe network flow pipe are Dg70, and scuttlebutt is Dg500 * 1100 automatically, V=0.2m
3, air compensation device is Dg500 * 200 automatically, V=0.02m
3, automatic air compensating valve is Dg15, and electromagnetic valve is JO11SA-15, and flow pipe is Dg50, and air pressure tank is Dg1000 * 2600, V=2.0m
3A pump and No. two pumps are the 2BA-6 type, No. one with No. two pressure controllers be the YTK-03 type.P is little=0.2MPa, and P is big=0.3MPa, when Q is big=30m
3/ h.Replace the coordinated operation test through continuous two pumps of half a year, reached the water supply requirement of design fully, the phenomenon of leaking or not drawing water never appearred in aqueduct.
