Description

The pipe network Pressure-superposed water supply equipment that regulating tank and the auxilliary pump of compensation are arranged

Technical field

The utility model relates to a kind of pipe network Pressure-superposed water supply equipment, relates in particular to the syndeton of this pipe network Pressure-superposed water supply equipment.

Background technology

Traditional automatic water supply equipment is to be the secondary booster supply equipment at water source with the pond, and the air pressure tank that connects by the equipment delivery port during shutdown is kept pressure.This secondary booster supply equipment constitutes simple, and operation control is convenient.Its shortcoming is that energy consumption is big, water source, pond vulnerable to pollution.

Beginning emerging pipe network Pressure-superposed water supply equipment in recent years directly is the water source with the city planting ductwork, because system is airtight, and pressurized water supply on municipal hydraulic pressure basis, how many differences what mends, and has health and energy-conservation two big advantages.But pipe network Pressure-superposed water supply equipment is in the past limit by minimum water services force value often, just can only stop to supply water when municipal ductwork pressure is near or below minimum water services force value, and the not enough regional water use peak period of pressure of supply water cuts off the water in short-term to cause part.

Summary of the invention

The utility model technical issues that need to address have provided a kind of pipe network Pressure-superposed water supply equipment that regulating tank and the auxilliary pump of compensation are arranged, and 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: the water inlet pipe of city planting ductwork has first pressure sensor and first flap valve that is connected water inlet pipe one end on the water inlet pipe; The other end of first flap valve connects an end that is composed in series by the main pump and second flap valve; The other end that the main pump and second flap valve compose in series and barrier film jar or air pressure tank, second pressure sensor and user's pipe network join; Also comprise: the auxilliary pump of compensation; One end of the auxilliary pump of described compensation joins with the other end of first flap valve, and the other end of pump is assisted in compensation and regulating tank that top has air inlet and exhaust valve joins.

Compared with prior art, the beneficial effects of the utility model are: be particularly suitable for only having pressure of supply water deficiency in short-term, need improve the occasion of pressure of supply water in short-term and use; As made full use of the volume of regulating tank, all the volume of regulating tanks all be used as water storage, can keep the not enough period water supply of pressure of supply water for more time.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

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: the water inlet pipe 1 of city planting ductwork has first pressure sensor 2 and first flap valve 4 that is connected water inlet pipe 1 one ends on the water inlet pipe 1; The other end of first flap valve 4 connects an end that is composed in series by the main pump 5 and second flap valve 6; The other end that the main pump 5 and second flap valve 6 compose in series and barrier film jar or air pressure tank 7, second pressure sensor 8 and user's pipe network 9 join; Also comprise: the auxilliary pump 3 of compensation; One end of the auxilliary pump 3 of described compensation joins with the other end of first flap valve 4, and the other end of pump 3 is assisted in compensation and regulating tank 11 that top has air inlet and exhaust valve 10 joins;

The metered flow of the auxilliary pump 3 of described compensation has only some/one of main pump 5 metered flows.

Operating principle of the present utility model is as follows: the water of city planting ductwork enters regulating tank 11 by the auxilliary pump 3 of water inlet pipe 1, flap valve 4 and compensation, the air that regulating tank is 11 li is discharged by the air inlet and exhaust valve 10 of band air filter and is filled regulating tank 11 up to water, closes air inlet and exhaust valve 10 automatically; The water that enters water inlet pipe 1 simultaneously laminates pressurized water supply by second flap valve 6 to user's pipe network 9 by main pump (pump group) 5, enters barrier film jar or air pressure tank 7 pressurizes simultaneously; Water supply volume minimizing when user's pipe network 9; second sensor, 8 sensed pressure reach a certain setting value; main pump 5 is shut down; keep the pressure of user's pipe networks 9 and deal with a small amount of water in user's pipe network 9 by barrier film jar or air pressure tank 7; the dischargeable capacity water yield up to clean barrier film jar of consumption or air pressure tank 7; second sensor, 8 sensed pressure are got back to the setting lower limit, and main pump (pump group) 5 restarts.

When first pressure sensor, 2 perception municipal ductwork pressures on the water inlet pipe 1 during near minimum water services force value, start the auxilliary pump 3 of compensation, water in the regulating tank 11 is mended the inlet into main pump (pump group) 5, air enters regulating tank 11 because regulating tank 11 middle water levels descend by the air inlet and exhaust valve 10 of being with air filter, make in the regulating tank 11 pressure reduce to zero, the adding of the inlet of main pump (pump group) 5 from compensating the water of auxilliary pump 3, city planting ductwork reduces the water yield that enters water inlet pipe 1; Main pump (pump group) 5 is continued to laminate pressurized water supply to user's pipe network 9, and wherein a part is from regulating tank 11, and another part is from city planting ductwork.Because reduced the water supply of city planting ductwork, the pressure of city planting ductwork no longer descends.Because the metered flow of the auxilliary pump 3 of compensation generally has only some/one of booster pump 5 metered flows; moisture storage capacity in the regulating tank 11 can be kept the output of several times; go over up to the not enough period of of short duration pressure of supply water; the auxilliary pump 3 of compensation is shut down; regulating tank 11 stores up full water again, prepares the not enough period of the next of short duration pressure of supply water of reply.

In order to keep the water storage in the regulating tank 11 fresh, (such as 24 hours) also will regularly start the auxilliary pump 3 of compensation even the situation of of short duration pressure of supply water deficiency does not take place in setting-up time, extract the water storage in the regulating tank 11 out, change the water that comes of the fresh city planting ductwork of storage.

Because the auxilliary pump 3 of compensation is contained between first flap valve 4 and regulating tank 11 of water inlet pipe 1, as long as start or stop water or water stored state that the auxilliary pump 3 of compensation can change regulating tank 11, needn't add switching device shifter in addition, therefore the utlity model has very high reliability.
