Abstract
The utility model is applicable to the process field that supplies water, a kind of water system of being interrupted is provided, described system comprises water tank, supply-water pump and automatic valve, described water tank is communicated to water spot by described supply-water pump, automatic valve successively, between the port of export of described supply-water pump and water tank, be also communicated with bleed off pipe, described bleed off pipe is provided with the overflow valve of automatically opening or closing according to overflow inner pipe water pressure size.In the utility model, in the time needing water with water spot, automatic valve is opened, overflow valve cuts out, and realizes normal water supply, in the time using water spot without water, automatic valve is closed, overflow valve is opened, supply-water pump circulation is drawn water, and supply-water pump, in continuous running status, is realized the interruption with water spot is supplied water like this, avoid supply-water pump frequent start-stop, extend the application life of supply-water pump and automatic valve.
Description
Technical field
The utility model belongs to water supply process field, relates in particular to a kind of water system of being interrupted.
Background technology
As shown in Figure 1, traditional interruption water system comprises a water tank 1, by supply-water pump 2, automatic valve 3, and lays corresponding water supply line the water in water tank is delivered to and uses water spot.In the time needing water with water spot, first start supply-water pump 2, then open automatic valve 3; In the time not needing water with water spot, first close automatic valve 3, then stop supply-water pump 2.Because with water spot being is interrupted water; therefore supply-water pump will be along with the demand with water spot corresponding unlatching or close; in the time being frequently interrupted water with water spot; supply-water pump also must be followed frequent start-stop; frequent start-stop can affect the application life of supply-water pump, and the huge water impact of supply-water pump frequent starting moment also can be damaged automatic valve.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of water system of being interrupted, and is intended to solve in existing water system, and supply-water pump need to, according to using water spot frequent start-stop, affect the technical problem in the application life of supply-water pump and automatic valve.
The utility model is to realize like this, a kind of water system of being interrupted, comprise water tank, supply-water pump and automatic valve, described water tank is communicated to water spot by described supply-water pump, automatic valve successively, between the port of export of described supply-water pump and water tank, be also communicated with bleed off pipe, described bleed off pipe is provided with the overflow valve of automatically opening or closing according to overflow inner pipe water pressure size.
Further, the arrival end of described supply-water pump is connected to described water tank bottom by pipeline.
Further, described bleed off pipe one end is connected to the port of export of described supply-water pump, and the other end is connected to described water tank top.
The beneficial effects of the utility model are: in the utility model, overflow valve can automatically open or cut out according to overflow inner pipe water pressure size, and overflow valve is opened in the time that hydraulic pressure is higher, when lower, closes; In the utility model, supply-water pump is in continuous running status, in the time needing water with water spot, automatic valve is opened, now because supply-water pump pressure release causes the hydraulic pressure in bleed off pipe relatively low, overflow valve can cut out automatically, thereby assure feed water pump is to the normal water supply with water spot; In the time not needing water with water spot, automatic valve is closed, now because building the pressure, supply-water pump cause the hydraulic pressure in bleed off pipe relatively high, overflow valve can be opened automatically, thereby make the import and export pipeline of supply-water pump unimpeded, supply-water pump still can normally be worked, so just can make supply-water pump move continuously and realize the interruption with water spot is supplied water, avoid supply-water pump frequent start-stop, extend the application life of supply-water pump and automatic valve.
Brief description of the drawings
Fig. 1 is the structure chart of existing interruption water system;
Fig. 2 is the structure chart of the interruption water system that provides of the utility model embodiment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
For technical scheme described in the utility model is described, describe below by specific embodiment.
Fig. 2 shows the structure of the interruption water system that the utility model embodiment provides, and only shows for convenience of explanation the part relevant to the utility model embodiment.
The interruption water system that the present embodiment provides, comprise water tank 1, supply-water pump 2 and automatic valve 3, described water tank 1 is communicated to water spot by described supply-water pump 2, automatic valve 3 successively, water tank 1, supply-water pump 2, automatic valve 3 and with connecting by pipeline between water spot, between the port of export of described supply-water pump 2 and water tank 1, be also communicated with bleed off pipe 4, described bleed off pipe 4 is provided with the overflow valve 5 of automatically opening or closing according to overflow inner pipe water pressure size.As the concrete preferred embodiment of one, the arrival end of described supply-water pump 2 is connected to described water tank 1 bottom by pipeline.Described bleed off pipe 4 one end are connected to the port of export of described supply-water pump 2, and the other end is connected to described water tank 1 top.Arrange and be more convenient for supply-water pump and draw water like this.
Overflow valve 4 open pressure and closing presure can arrange and adjust, overflow valve is opened in the time that overflow inner pipe water pressure is higher, when lower, close.In the time needing water with water spot, automatic valve 3 is opened, and now, because supply-water pump 2 pressure releases cause the hydraulic pressure in bleed off pipe 4 relatively low, overflow valve 5 can cut out automatically, thereby assure feed water pump 2 is to the normal water supply with water spot; In the time not needing water with water spot, automatic valve 3 is closed, now because building the pressure, supply-water pump 2 cause the hydraulic pressure in bleed off pipe 4 relatively high, overflow valve 5 can be opened automatically, thereby it is unimpeded to make supply-water pump import and export pipeline, supply-water pump still can normally be worked, and supply-water pump injects again water tank after the water in water tank is extracted out.So just can make supply-water pump move continuously and realize the interruption with water spot is supplied water.
In this enforcement, in the time needing water with water spot, automatic valve is opened, overflow valve cuts out, and realizes normal water supply, in the time using water spot without water, automatic valve is closed, overflow valve is opened, supply-water pump circulation is drawn water, and supply-water pump, in continuous running status, is realized the interruption with water spot is supplied water like this, avoid supply-water pump frequent start-stop, extend the application life of supply-water pump and automatic valve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
