Description
Technical field
The present invention relates to injection product technical field, refer in particular to a kind of gas heater water-saving system with induction apparatus.
Background technology
Nowadays, although a lot of conventional water heaters can heat cold water very soon, but between water heater and pipe outlet, the cold water of this section of pipeline can not get heating, a lot of users first bleed off this part cold water, waste resource, and distance is longer between water heater and pipe outlet, the water resource of hot standby waste also can be larger so.Although some family combines in this part cold water in bathroom inner pressurd vessel and re-used, take bathroom floor space larger, and secondary utilizes inconvenience.In addition, conventional water heaters is unstable, sometimes hot and sometimes cold at the first few minutes leaving water temperature of work, cannot meet bather's comfort level.Tradition water recycling system needs extra power set as water pump provides power to system, also causes waste electric energy simultaneously and produces noise.
Summary of the invention
The technical problem to be solved in the present invention is, for the shortcoming existing in background technology and problem improvement and bring new ideas in addition, a kind of simple in structure, injection power set of not consuming energy are provided, low-pressure water injection is entered in water under high pressure, and be equipped with the water reclamation system of control module, and can assure feed water temperature stabilization.
To achieve these goals, the present invention is by the following technical solutions: a kind of gas heater water-saving system with induction apparatus, is mainly made up of storage tank (7), check-valves (6) (11), magnetic valve (1) (2) (12), spacing meter (8) (9), induction apparatus (13), temperature sensor (3), temperature-adjusting device (15), control module, water inlet pipe and water outlet pipe etc.Water temperature is not in the case of reaching the temperature of user's setting, water enters storage tank and stores, again because the effect of induction tunnel injection, low-pressure water injection is entered to high-pressure water pipe, and mix with the hot water by water heater, so circulation, until water temperature reaches set temperature, by control module opens solenoid valve (2), outlet pipe flows out steady temperature hot water.
When the temperature that the hot water outlet pipe's (4) who records when temperature sensor (3) temperature arranges lower than user and spacing meter (8) do not measure water level signal, control magnetic valve (2) in normally off, magnetic valve (1) is in normally open.The hot water that comes from gas heater enters induction apparatus entrance, while flowing through throttling element in pipeline, flow velocity will form local contraction at place of throat, flow velocity increases, static pressure reduces, so just produced pressure reduction at larynx neck and induction apparatus water inlet pipe, will come from the cold water introducing device of mixing chamber (20) and mix, the water after temperature improves flows out from induction apparatus outlet.
The first preferred embodiment based on such scheme induction apparatus of the present invention (13) size is: import (16) outlet (17) diameter is identical, with throat diameter ratio be 2, the angle of flare of import and export is all 15 degree.
The second preferred embodiment of the double-venturi tube based on the first preferred embodiment is: import (16) outlet (17) diameter is identical, with throat diameter ratio be 3, the angle of flare of import and export is all 18.5 degree.
The second preferred embodiment of the double-venturi tube based on the first preferred embodiment is: import (16) outlet (17) diameter is identical, with throat diameter ratio be 4, the angle of flare of import and export is all 20 degree.
When the hot water outlet pipe's (4) who records when temperature sensor (3) temperature reaches temperature that user arranges or spacing meter (8) and measures water level signal, control magnetic valve (2) in normally open, magnetic valve (1) is in normally off, the water circulatory system of no longer flowing through.
In the time that spacing meter (9) does not record water level signal, magnetic valve (12) is normally closed, and in the time that spacing meter (9) records water level signal, magnetic valve (12) often leaves.
The present invention does not need extra power set just can, for water reclamation system provides circulation power, reduce power consumption, there is no noise, energy-saving and environment friendly.
The present invention installs simply, can directly be installed on running water pipe and water heater, easy to use, saves ground space, and effluent temperature constancy is easy to use comfortable.
