Abstract
The utility model relates to a double-pipe water supply device, in particular to double-pipe water supply device. The double-pipe water supply device comprises two pipelines including a first pipeline and a second pipeline, wherein the first pipeline is a pipeline placed between water equipment and a first automatic valve. A third valve is placed between the first automatic valve and a water return point. The second pipeline is a pipeline placed between the first automatic valve and the third valve. A second automatic valve is placed between the first pipeline and the second pipeline and the third valve is a one-way valve. The double-pipe water supply device adopts two pipelines to supply water and the two pipelines can simultaneously supply water and simultaneously circulate with the minor-cycling when water is not used. The water inside the pipes is always in flow condition, thereby achieving bacteria-free requirement.
Description
Technical field
The utility model relates to a kind of water supply installation, relates in particular to a kind of dual circuit water supply installation.
Background technology
In water system; the water terminal is water not; water manufacturing system just needs to shut down; but hydropexis will bring bacteria growth problems after shutting down in equipment or pipeline; therefore strictly control at the bacterial micro-organism index request, begin to introduce the partial circulating concept in the system of aseptic requirement, namely when water or storage tank were not full, product water need be got back to the water making device water inlet end and form circulation; guarantee that the water in the equipment pipe is in flow regime, reduces growing of bacterium.
But small-size circulating device all adopts the single tube circulation now, and as shown in Figure 1, V1, V2 valve are by switching to realize normally water processed and partial circulating.This device exists a problem, and with under the water state, V1 valve opening, the water in the V2 valve closing, circulation line (dotted line) are mobile, are in the stagnant water state, are easy to breed bacteria, can't reach aseptic requirement normally.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art, and a kind of dual circuit water supply installation is provided, and two pipelines supply water simultaneously during water, two pipeline synchronous circulatings during without water circulation, and pipeline is without stagnant water.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of dual circuit water supply installation, comprise water inlet, water making device and terminal device, water inlet is connected with water making device, water making device is connected with terminal device, be provided with the backwater point between water inlet and the water making device, be provided with the first automatic valve between water making device and the terminal device, comprise two pipelines, be respectively the first pipeline and the second pipeline, the first pipeline is that water making device is to the pipeline between the first automatic valve, the first automatic valve is to being provided with the 3rd valve between the backwater point, the second pipeline is the pipeline between the first automatic valve to the three valves, is provided with the second automatic valve between the first pipeline and the second pipeline.
As preferably, the 3rd valve is one way valve.
During normal water supply, such as Fig. 2, the first automatic valve V1, the second automatic valve V2 are in opening, and flow through the first pipeline, two pipelines of the second pipeline of water supply current enters terminal device.Because the 3rd valve V3 is one way valve, so the water in the backwater point can not enter in the pipeline.
During partial circulating, such as Fig. 3, the first automatic valve V1, the second automatic valve V2 are in closed condition, and the loop of recirculated water by two pipelines is back to the backwater point through the 3rd valve V3 again and enters the partial circulating state.
The utility model adopts two pipelines to supply water, and two pipelines supply water simultaneously during water, two pipeline synchronous circulatings during the water partial circulating not, and the water in the pipe is in flow regime all the time, reaches aseptic requirement.The second automatic valve V2 and two valves of the 3rd valve V3 satisfy the 3D requirement in the technique manufacturing, and there is not the stagnant water situation in these two states current that supply water, circulate through all pipelines, really accomplish aseptic.
Description of drawings
Fig. 1 is the structural representation of water supply installation of the prior art;
Fig. 2 is the normal water supply water flow state diagram of a kind of dual circuit water supply installation described in the utility model;
Water flow state diagram when Fig. 3 is the partial circulating of a kind of dual circuit water supply installation described in the utility model.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1 to 3.
Embodiment
A kind of dual circuit water supply installation, shown in Fig. 2 to 3, comprise water inlet 1, water making device 3 and terminal device 6, water inlet 1 is connected with water making device 3, water making device 3 is connected with terminal device 6, be provided with backwater point 2 between water inlet 1 and the water making device 3, be provided with the first automatic valve 5 between water making device 3 and the terminal device 6, comprise two pipelines, be respectively the first pipeline 8 and the second pipeline 9, the first pipeline 8 is the pipeline between water making device 3 to first automatic valves 5, the first automatic valve 5 is to being provided with the 3rd valve 7 between the backwater point 2, the second pipeline 9 is the pipeline between the first automatic valve 5 to the 3rd valves 7, is provided with the second automatic valve 4 between the first pipeline 8 and the second pipeline 9.The 3rd valve 7 is one way valve.
During normal water supply, as shown in Figure 2, V1 is the first automatic valve 5, and V2 is the second automatic valve 4, and V1 and V2 are in opening, and flow through the first pipeline 8,9 two pipelines of the second pipeline of water supply current enters terminal device 6.V3 is the 3rd valve 7, because V3 is one way valve, so the water in the backwater point 2 can not enter in the pipeline.
During partial circulating, as shown in Figure 3, V1 and V2 are in closed condition, and the loop of recirculated water by the first pipeline 8,9 two pipelines of the second pipeline is back to backwater point 2 through V3 again and enters the partial circulating state.
In the prior art, as shown in Figure 1, adopt the single tube circulation, V1, V2 are by switching to realize normally water processed and partial circulating.This device exists a problem, and with under the water state, V1 opens normally, and V2 closes, and the water in the circulation line (dotted line) does not flow, and is in the stagnant water state, is easy to breed bacteria, can't reach aseptic requirement.
And the utility model adopts two pipelines to supply water, and the first pipeline 8,9 two pipelines of the second pipeline supply water simultaneously during water, two pipeline synchronous circulatings during the water partial circulating not, and the water in the pipe is in flow regime all the time, reaches aseptic requirement.The second automatic valve V2 and two valves of the 3rd valve V3 satisfy the 3D requirement in the technique manufacturing, and there is not the stagnant water situation in these two states current that supply water, circulate through all pipelines, really accomplish aseptic.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
