The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
With reference to shown in Figure 1, a kind of pressure watering device, comprise air pressure tank 1, auxiliary pump 2, three-way switch valve 3, be connected with inlet and outlet pipe 13,14 at described air pressure tank 1, the outlet pipeline 14 of described air pressure tank 1 is connected with the entrance of auxiliary pump 2, the inlet pipeline 13 of air pressure tank 1 is connected with the automatic intake-outlet A of three-way switch valve 3, and the outlet of described auxiliary pump 2 is connected with the passive intake-outlet C of three-way switch valve 3, and the public intake-outlet B of three-way switch valve 3 is connected for water unit with outside.
When auxiliary pump 2 is in stopped status, air pressure tank 1 is communicated with outside inlet and outlet pipe through automatic intake-outlet A and the public intake-outlet B of three-way switch valve 3, namely can to air pressure tank 1 interior moisturizing, also can outwards be supplied water by air pressure tank 1.At this moment this air pressure tank 1 water facilities is with usually the air pressure tank principle is identical, when pressure water supply so that air pressure tank 1 internal pressure when dropping to minimum working pressure P1, just can't continue pressure water supply on demand, so the effective water capacity that only depends on pressure water supply to provide is very limited.
For improving the effective water capacity of air pressure tank, when this programme is down to lower limit P1 when air pressure tank 1 operating pressure, start auxiliary pump 2 operations, at this moment the passive intake-outlet C of three-way switch valve, public intake-outlet B are connected, automatically intake-outlet A closes simultaneously, auxiliary pump 2 is take air pressure tank 1 as the water source, can continue the output that provides certain, and keep being not less than lower limit P1 to outside pressure of supply water.
Suppose 1 water storage of auxiliary pump 2 operation discharge air pressure tanks, make air pressure tank 1 pressure drop to certain value that is lower than P1, represent with P11, when making absolute pressure be down to 0.5 than P11/P2, then be equivalent to air pressure tank 1 dischargeable capacity and rise to 50% of total measurement (volume), when making absolute pressure be down to 0.4 than P11/P2, then be equivalent to air pressure tank 1 dischargeable capacity and rise to 60% of total measurement (volume), as seen effective water capacity of this pressure water supply facility is comprised of two parts: a part is the water yield of discharging by gas expansion from the upper pressure limit to the low pressure limit, another part is to start auxiliary pump 2 to continue the water yield of discharging, thus greatly improved air pressure tank effectively go out water capacity.Under same dischargeable capacity condition, this technical scheme can reduce the total measurement (volume) of air pressure tank greatly in other words.
Auxiliary pump in the technical program generally adopts centrifugal pump, consider that auxiliary pump compares with the main pump in the complete supply equipment, flow, lift, power are less, the efficient of small flow centrifugal pump is lower, for raising the efficiency the positive displacement pump that can adopt certain form of structure, for example adopt the RO(counter-infiltration) diaphragm pump.
Three-way switch valve in the technical program can adopt the internal construction that is similar to vacuum breaker.The automatic intake-outlet A of three-way switch valve is corresponding with the blow vent of vacuum breaker, and public intake-outlet B is corresponding with the delivery port of vacuum breaker, and passive intake-outlet C is corresponding with the water inlet of vacuum breaker.
When auxiliary pump 2 was shut down, automatic intake-outlet A and the public intake-outlet B of three-way switch valve were in connected state, during auxiliary pump 2 operation, promoted flap and closed automatic intake-outlet A, and public intake-outlet B and passive intake-outlet C connect simultaneously.
With reference to Fig. 2, the outside water unit that supplies is comprised of two water supply branch roads that are arranged in parallel in pipe network, wherein water check valve 8 is connected with main pump 6 and is formed a water supply branch road, water check valve 9 is connected with main pump 7 and is formed a water supply branch road, a termination main-supply road 4 behind two water supply branch circuit parallel connections, other end exit pipeline 11, water check valve 8,9 is used for preventing that the aqueous reflux of pipe network from entering.
Externally for being provided with pressure sensor 5 on the main-supply road 4 in the water unit, in order to detect the pressure in the main-supply road, be provided with pressure sensor 10 at export pipeline 11, in order to detect the pressure in the pipeline 11 for export, export pipeline 11 is connected to user side 12.Main-supply road 4 connects external water source.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
