The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the magnetic valve 4 that on hot water generator 5 cold water inflow pipe 6, is provided with, the water flow pressure sensor 8 that on hot water generator 5 hot water discharge pipe 7, is provided with, on the hot water discharge pipe 7 between water flow pressure sensor 8 and the hot water generator 5, be provided with water pump 9, cold water inflow pipe 6 construction company's siphunculus 10 between the hot water discharge pipe 7 between water pump 9 and the water flow pressure sensor 8 and magnetic valve 4 and hot water generator 5, on this communicating pipe 10, be provided with magnetic valve 3, on the pipeline between water pump 9 and the hot water generator 5, be provided with and replenish pipe 11, replenish on the pipe 11 magnetic valve 2 is set, this replenishes pipe 11 and joins with cold water source.
On hot water discharge pipe 7, be provided with magnetic valve 1, replenish on pipe 11 hot water discharge pipes 7 that are arranged between magnetic valve 1 and the water pump 9.
Water flow pressure sensor 8 comprises the housing 12 that is airtight, the two ends up and down of housing 12 are respectively equipped with water inlet pipe 13 and outlet pipe 14, be provided with at housing 12 inwalls and cut apart film 15, this is cut apart film 15 housing 12 inner spaces is divided into two seal chambers up and down, epicoele is communicated with water inlet pipe 13, cavity of resorption is communicated with outlet pipe 14, be provided with push rod 16 in the cavity of resorption inner walls, offer opening 17 on the film 15 in cutting apart above the push rod 16, the top of push rod 16 is connected with through opening 17 and stretches into guide post 18 in the epicoele, the external diameter of guide post 18 is less than the external diameter of push rod 16, the slip socket covers the cover plate 19 of opening 17 outside the guide post 18 in epicoele, and outside guide post 18, be with the epicoele back-moving spring 20 of compression, the lower end of epicoele back-moving spring 20 is against on the cover plate 19, and the upper end of epicoele back-moving spring 20 can be against cavity wall on the housing, also can be against on the installing plate 25, or be against on the cross bar 23, in cavity of resorption, cut apart the cavity of resorption back-moving spring 26 of wedging ring outside push rod 16 between film 15 and the housing 12.
One of them locating support 24 lower end in housing 12 cavity of resorptions are provided with magnet 27, are provided with proximity transducer 28 on 12 inwalls of the housing below the magnet 27.
The signal that water flow pressure sensor 8 spreads out of can be used to start water pump 9 when water flow pressure is too small, as long as also can there be current just to start water pump 9.Described magnetic valve 1 magnetic valve, 2 magnetic valves 3 and magnetic valve 4 are normally open type magnetic valve.
The course of work: the water (flow) direction of pipeline is as scheming:
In case delivery port water outlet, cutting apart film 15 to forming a negative pressure between the delivery port of outlet pipe 14, water inlet pipe 13 just increases to cutting apart 15 pressure of film, under the effect of pressure, cutting apart film 15 is out of shape downwards, make that cutting apart film 15 is out of shape with locating support provided thereon 24 downwards, because push rod 16 is fixed on the housing 12, so it is more and more littler with respect to distance between push rod 16 tops to cut apart film 15, until push rod 16 from opening 17 and through hole 22 internal projection, when cutting apart film 15 continuation distortion downwards, cut apart film 15 and continue compression cavity of resorption back-moving springs 26, the cover plate 19 that push rod 16 is about to be covered on the clamping plate 21 backs down overcoming under the extension elastic force situation of epicoele back-moving spring 20, makes cover plate 19 and clamping plate 21 have the space, this moment, water can flow in the cavity of resorption from epicoele, thereby opened the door of current.
When delivery port stops water outlet, the pressure differential between epicoele and the cavity of resorption disappears, and cuts apart film 15 and resets rapidly under the downward jacking force effect of the upwards jacking force of cavity of resorption back-moving spring 26 and epicoele back-moving spring 20.
Because cut apart the distortion of film 15, housing 12 is changes of a distance relatively, and be installed in the magnet 27 of cutting apart film 15 locating supports 24 lower ends and foreign material housing device is installed, just owing to needed information is sent in the change of distance, cavity of resorption back-moving spring 26 is to reset fast cutting apart film 15, the intensity of cavity of resorption back-moving spring 26 can be according to the hydraulic pressure adjustment, this water flow pressure sensor 8 is owing to can bear 100 ℃ high temperature, simultaneously, incrustation scale produces and also can not exert an influence to product, therefore, this product is applicable in the liquid of different temperatures, and is simultaneously durable in use.
The utility model is to adopt a water pump 9 to take into account the supercharging of cold water and hot water.And can the cold water after stored for a long time among the hot water discharge pipe 7 be circulated, reach the purpose that does not have cold water in the pipeline.Because ducted water can circulate, so can play the effect of freezing prevention tubing in winter.The utility model is very suitable to the occasion that adopts the hot water bag to supply water, for example solar water heater, electric heater and gas heater etc.Can supercharging when both can cold water adding water, also can supercharging during the hot water feedwater, and only use a water pump 9.And pipeline cold water and problem that winter, pipeline freezed have been solved again well.
Water flow sensing unit wherein, this is a high-precision water flow pressure sensor, and the reliability height, can use in 100 ℃ hot water fully.It has solved the existing reliability problems of water flow sensing unit in the market, and water flow sensing unit in the market generally can only use in being lower than 60～70 ℃ of environment.And can only be to having or not the current effect, ducted pressure size is then like water off a duck's back.
