Abstract

The utility model relates to intelligent dual-mode water supply equipment, which comprises a municipal pipe network, a water inlet control sensor, a municipal water intake control valve and a first check valve, wherein the water inlet control sensor, the municipal water intake control valve and the first check valve are connected with the municipal pipe network; the other end of the first check valve is connected with one end of a parallel branch which is formed by two series braches; each series branch is formed by connecting a first service valve, a main pump, a second check valve and a second service valve in series; and the other end of the parallel branch is connected with a gas pressure tank and a water outlet control sensor. The equipment also comprises an accessory pump; one end of the accessory pump is connected with the other end of the first check valve; and the other end of the accessory pump is connected with a water tank through a third check valve, and is also connected with a hydraulic control valve in the water tank through a water tank feeding control valve. The equipment has the advantages of fully utilizing the original pressure of the municipal pipe network, achieving the purpose of saving energy, feeding water when the municipal water is not enough, reliving the conflict in the peak period that the water demand is much larger than the water supply, and greatly improving the reliability of the water supply.

Description

The double mode supply equipment of intelligence

Technical field

The utility model relates to the supply equipment technical field, particularly has the pipe network Pressure-superposed water supply equipment (claiming intelligent double mode supply equipment again) of flow supply or alternate source.

Background technology

Pipe network Pressure-superposed water supply equipment be emerging in recent years a kind of be the supply equipment at water source directly with the city planting ductwork, it has cancelled traditional reservoir, directly draw water from city planting ductwork and to be forced into the user, because whole pipe network system is airtight, and be pressurized water supply on municipal hydraulic pressure basis, how many differences what mends, and has health and energy-conservation two big advantages, extensively admitted in the regional result of use of tap water flow abundance.

But there are the following problems for this product at present: in city planting ductwork water supply flow instability, or the water use peak phase, when the municipal administration flow can not satisfy user's water, the pipe network Pressure-superposed water supply equipment of main flow all is the deficiency that compensates municipal water supply by the supporting surge tank of water inlet, owing to need pressure-bearing, surge tank should not dispose excessive, its dischargeable capacity is limited especially, can only play instantaneous moisturizing effects, can not effectively solve the problem or the water contradiction of buffering water use peak phase of municipal underfed, in the sufficient inadequately or intermittently sufficient area of municipal flow even disabled.

Summary of the invention

The utility model technical issues that need to address have provided the double mode supply equipment of a kind of intelligence, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: city planting ductwork and the control of the water inlet on city planting ductwork sensor, municipal water inlet control valve and first flap valve; The other end of first flap valve connects an end that is connected in series behind first service valve, main pump, second flap valve and second service valve successively and connects by two groups, and the other end that connects is controlled sensor with air pressure tank and delivery port and joined; Also comprise: an auxilliary pump; One end of described auxilliary pump is connected with the other end of first flap valve, and the other end of auxilliary pump joins by the 3rd flap valve and water tank; The other end of auxilliary pump also links to each other with hydraulic control valve in the water tank by water tank moisturizing control valve.

Compared with prior art, the beneficial effects of the utility model are: both made full use of original pressure of city planting ductwork, reached purpose of energy saving, can carry out the flow supply again when municipal underfed, alleviate the water contradiction of water use peak phase, improved the reliability that supplies water greatly.

Description of drawings

Fig. 1 is the utility model structural representation;

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

As seen from Figure 1: the utility model comprises: city planting ductwork 1 and the control of the water inlet on city planting ductwork 1 sensor 2, municipal water inlet control valve 3 and first flap valve 4; The other end of first flap valve 4 connects an end that is connected in series first service valve 11, main pump 12, second flap valve 13 and second service valve, 14 backs successively and connects by two groups, and the other end that connects joins with air pressure tank 15 and delivery port control sensor 16; Also comprise: an auxilliary pump 5; One end of described auxilliary pump 5 is connected with the other end of first flap valve 4, and the other end of auxilliary pump 5 joins with water tank 8 by the 3rd flap valve 9; The other end of auxilliary pump 5 also links to each other with hydraulic control valve 7 in the water tank 8 by water tank moisturizing control valve 6.

Flow supply of the present utility model realizes in the mode of " nourishment source ", does not need to switch the duty of main pump, has simplified control logic, has improved the comfort level of water; Simultaneously can effectively prevent the excessive suction of main pump, not influence other user's normal water supply city planting ductwork.Stop the moisturizing of city planting ductwork when assisting pump work, not only can fully guarantee pressure of supply water and the flow of city planting ductwork under this operating mode, and can improve energy-saving effect water tank.

Detailed action of the present utility model is as described below:

When the flow of city planting ductwork 1 can satisfy user's water, 12 of main pumps were the water source with city planting ductwork 1.In the water use peak phase, when the flow of city planting ductwork 1 can not satisfy user's water fully, water tank moisturizing control valve 6 was closed, and auxilliary pump 5 starts, the deficiency of the supply municipal administration flow that from water tank 8, draws water, and at this moment, main pump 12 is the water source with city planting ductwork 1 and water tank 8 simultaneously; When the pressure that detects city planting ductwork 1 through water inlet control sensor 2 dropped to restriction pressure, municipal water inlet control valve 3 was closed, and water tank moisturizing control valve 6 is closed, and auxilliary pump 5 starts, the supply main pump that from water tank 8, draws water, and this moment, main pump was the water source with the water tank only.When the pressure of supply water of city planting ductwork 1 and flow recover just often, equipment automatically restores to normal operation condition.

When auxilliary pump 5 stopped, the water in the city planting ductwork 1 was through municipal water inlet control valve 3, flap valve 4, auxilliary pump 5, water tank moisturizing control valve 6 and hydraulic control valve 7 extra feed tanks.Close water tank moisturizing control valve 6 earlier before auxilliary pump 5 operations, the water in the water tank 8 is through flap valve 9, auxilliary pump 5 forced feed main pumps 12.It is interlocking on pipeline that feed tank moisturizing and water tank externally supply water, and both can not carry out simultaneously.

Auxilliary pump 5 in the utility model is mainly detected by 2 pairs of city planting ductworks of water inlet control sensor 1 by switch board 17 judges that back control opens, stops, and municipal flow is long-time also to be needed to consider when sufficient to refresh the water periodically by switch board 17 Based Intelligent Control water tanks and guarantee water quality safety.Main pump 12 is mainly controlled firing platform number, dormancy by the feedback pressure of delivery port control sensor 16 or is shut down pressurize (shut down the back and realize pressurize by air pressure tank 15) by switch board 17.Difference on the function has determined auxilliary pump 5 and main pump 12 will consider stand by pump respectively when design.
