Abstract
The utility model relates to a terminal water supplying device for a municipal water supply pipe network. The utility model is characterized in that the utility model comprises a one-way valve, a water pump which is connected in series with the one-way valve through a water delivery pipe, a controller used for controlling the operation of the water pump and a high-position water-storage tank; the high-position water-storage tank a connected with a water pipe arranged between the one-way valve and the water pump through a branch pipe; the high-position water-storage tank is provided with an automatic exhaust overflow-preventive valve. The utility model can not generate negative pressure for the municipal water supply pipe network in application, and can effectively use the pressure energy of the water from the water supply pipe network.
Description
The utility model relates to a kind of terminal water supplying device of municipal water supply pipe network.
At present, the program mode (PM) of living water generally is: municipal water supply pipe network → ground reservoir → water pump → high level cistern → each residential water.In said process from the band pressure of municipal water supply pipe network can water just become not with the water of energy after entering reservoir, must can inject high level cistern through the water pump pressurization then, inevitably like this to cause energy loss.
The purpose of this utility model is that a kind of municipal water supply pipe network terminal water supplying device will be provided, and it not only can not produce negative pressure to the municipal water supply pipe network in application, and can effectively be used to the pressure energy of the water of self-water-supply pipe network.
Construction features of the present utility model are the water pumps that comprise one way valve, are connected in series mutually through a water-supply-pipe and one way valve, controller in order to control of pump work, with high-order water tank, this high position water tank is connected with the water pipe of being located between one way valve and the water pump through an arm, also is provided with the automatic vent anti-overflow valve on the high-order water tank.
When the municipal water supply pipe network had certain hydraulic pressure, the water in the pipe network just can flow into high-order water tank through one way valve and water-supply-pipe and arm.When the water level in the high-order water tank is lower than the installation site of automatic vent anti-overflow valve, inner air and the outside atmosphere of jar communicates, when water level is higher than automatic vent and puts the installation site of the valve that overflows, jar inner air and outside atmosphere are isolated, and the pressurized energy storage is not until balance each other with city planting ductwork hydraulic pressure (this moment, water pump was worked).When user's via controller starts pump working, because the hydraulic pressure of water pump entrance point is greater than zero, water pump is lower than the rated speed running, can produce the required pressure of supply water of user, so power consumption also lower (ideally the power of water pump consumption is the three cubed function of pump rotary speed).When lower and water pump output flow is big when the municipal water supply pipe network water pressure, the water level in jar will descend gradually, and the water pump inlet pressure also descends thereupon gradually, but will never be lower than atmospheric pressure.Therefore, the utility model not only can not tied the municipal water supply pipe network and cause negative pressure in application, and when operate as normal, can effectively be used to the pressure energy from the water of municipal water supply pipe network again, thereby reduces the water pump operation energy consumption.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the organigram of embodiment one.
Fig. 2 is the organigram of embodiment two.
With reference to Fig. 1, the water pump 3 that embodiment one comprises one way valve 1, is connected in series mutually through a water-supply-pipe 2 and one way valve, controller in order to control of pump work, with high-order water tank 4, this high position water tank is connected with the water-supply-pipe of being located between one way valve and the water pump 2 through an arm 5, also is provided with automatic vent anti-overflow valve 6 on the high-order water tank.
Fig. 2 is embodiment 2 organigrams that have identical inventive concept with embodiment one.It comprises water delivery one way valve 1, and through the water pump 3 that a water-supply-pipe and water delivery one way valve are connected in series mutually, in order to the controller and the high-order reservoir 8 of control of pump work, high-order reservoir is provided with water inlet pipe 10 and the outlet pipe 11 by float valve 9 controls.The entrance point of the lower end of water inlet pipe and water delivery one way valve links, and outlet pipe links through the entrance point of outlet valve and water pump.When the hydraulic pressure of municipal water supply pipe network surpasses normal pressure or when big, the water in the pipe network just can be poured into high-order reservoir (at this moment, water pump is in the state of quitting work) through water inlet pipe 10.When user's via controller starts pump working, if waterline network hydraulic pressure is bigger, water from waterline network just is sent to the water pump import through one way valve 11, if waterline network hydraulic pressure is lower, the water in the high-order reservoir just flows to the water pump import through going out water one-way valve 11 and outlet pipe.In like manner, because the existence of high-order reservoir, on the one hand, it has guaranteed that the hydraulic pressure of water pump entrance point is more than or equal to zero, on the other hand, it can convert the pressure from the water of pipe network to have certain potential energy in the high-order reservoir water again, last return again for the water pump entrance point have certain pressure can water, reduce the purpose that the water pump rated speed reduces the water pump power consumption thereby reach.
The utility model is novel, and is simple in structure, good energy-conserving effect, and its market prospects are considerable.
