Description
Technical field
The utility model relates to the control of the fluid heater that heat-generating device is generally arranged or the configuration of safety device, relates in particular to a kind of gas heater temperature rise restraining device of cutting off the water.
Background technology
The existing gas heater that is used for bathing is cutting out cold water inlet to the blink of aqueous vapor interstage valve cut-out source of the gas, and the stationary water in the heater can be heated above the temperature of normality water outlet, and the temperature rise phenomenon occurs cutting off the water.When again it being opened in the blink after closing cold water inlet, the initial superheated water that flows out of hot water outlet pipe may cause the bather to be scalded or be uncomfortable.The problem that prior art exists is, do not have as yet so far to suppress the cut off the water practicability device of temperature rise phenomenon of gas heater efficiently.
Summary of the invention
Be to solve the problem that prior art exists, the utility model proposes a kind of gas heater temperature rise restraining device of cutting off the water.The technical scheme that adopts is as follows:
This gas heater temperature rise restraining device of cutting off the water, comprise heater, hot water outlet pipe and the cold water inlet that disposes water flow sensing unit, it is characterized in that being provided with the controller of employing water flow sensing unit as input block, be controlled by the controlled dibit water distribution valve that a delivery port of controller is connected with the water inlet of heater cold water inlet, the cold water straight pipe that water inlet is connected with another delivery port of controlled dibit water distribution valve, and one water inlet be connected with the delivery port of cold water straight pipe and three water service pipes that another water inlet is connected with heater hot water outlet pipe's delivery port, the water inlet of controlled dibit water distribution valve is connected with the delivery port of cold water inlet, and the delivery port of three water service pipes is connected with hot water outlet pipe's water inlet.
The cut off the water further feature of temperature rise restraining device of this gas heater is that controlled dibit water distribution valve can be the rotary dibit water distribution valve that is driven its rotation by the stepper motor of band reducing gear, also can be the electromagnetic type dibit water distribution valve of band timing means.
This gas heater cut off the water the temperature rise restraining device more further feature be that controller can adopt cpu chip and associated driver circuitry to form, and also can adopt logic circuit to form.
The utility model beneficial effect against existing technologies is modern design, compact conformation, form simply, convenient and practical, especially can suppress the gas heater temperature rise phenomenon that occurs cutting off the water efficiently, the user can enjoy the hot water of safety appropriateness, can not cause and scald or uncomfortable consequence.The utility model can be used as black box and is assembled in the gas heater, significantly improves properties of product.
Description of drawings
Accompanying drawing is a composition structural representation of the present utility model.
The specific embodiment
This gas heater temperature rise restraining device of cutting off the water, comprise heater 5, hot water outlet pipe 8 and the cold water inlet 4 that disposes water flow sensing unit 10, be provided with and adopt the controller 3 of water flow sensing unit 10 as input block, be controlled by the controlled dibit water distribution valve 2 that a delivery port of controller 3 is connected with the water inlet of heater cold water inlet 9, the cold water straight pipe 1 that water inlet is connected with another delivery port of controlled dibit water distribution valve 2, and one water inlet be connected with the delivery port of cold water straight pipe 1 and three water service pipes 7 that another water inlet is connected with heater hot water outlet pipe 6 delivery port, the water inlet of controlled dibit water distribution valve 2 is connected with the delivery port of cold water inlet 4, and the delivery port of three water service pipes 7 is connected with hot water outlet pipe 8 water inlet.
Cold water straight pipe 1 adopts the copper pipe of 6.5 millimeters of φ.Controlled dibit water distribution valve 2 is the rotary cast copper dibit water distribution valves that driven its rotation by the stepper motor with 38.5/1 reduction gear, when being in the normal state, close the water inlet of cold water straight pipe 1, external cold water from cold water inlet 4 all enters heater cold water inlet 9, and be in when suppressing the position, open the water inlet of cold water straight pipe 1 by setting value part, splitter section is from the external cold water of cold water inlet 4.Controller 3 adopts MCS51 series monolithic 87F51 and associated driver circuitry to form.
When the gas heater normality is worked, controlled dibit water distribution valve 2 position that is in the normal state, whole external cold water enter heater 5 heating through cold water inlet 4, controlled dibit water distribution valve 2 and heater cold water inlet 9.Hot water heater via hot water outlet pipe 6, three water service pipes 7 and hot water outlet pipe 8 are flowed out.
After cold water inlet 4 is closed, send control signal as the water flow sensing unit 10 of input block and make the stepper motor of controller 3 by the band reduction gear drive controlled dibit water distribution valve 2 to be in and to suppress the position.When again it being opened in the blink after closing cold water inlet 4, by setting value, have only the external cold water of part to enter heater 5 heating through cold water inlet 4, controlled dibit water distribution valve 2 and heater cold water inlet 9, the external cold water of being shunted of another part enters three water service pipes 7 through cold water inlet 4, controlled dibit water distribution valve 2 and cold water straight pipe 1, the high-temperature-hot-water that flows out with hot water outlet pipe 8 mixes, to suppress to cut off the water the temperature rise phenomenon efficiently.Through the second of the order of magnitude of setting after the time, the water inlet of cold water straight pipe 1, the work of gas heater normality are closed in the controlled again position that is in the normal state of controlled dibit water distribution valve 2.
