Abstract
The utility model relates to an automatic on-off control device of a valve of a fuel gas water heater and a fuel gas water heater, the air intake valve of the on-off control device is of an electromagnetic valve, an electric control end of the electromagnetic valve is connected with an output end of a controller, and an input end of the controller is connected with the output end of a water flow sensor arranged on a water inlet pipe when the water flow sensor is used. Since the utility model adopts the electromagnetic valve as a gas intake valve, and the utility model adopts the water flow sensor to detect water flow, as long as water flow passes through the water inlet pipe, the utility model can control the gas inlet valve to open reliably; when the water inlet pipe has no water flow, the gas inlet valve can be controlled to close reliably. The defect that the fuel gas water heater is unable to have normal work because of low water pressure is eliminated, and the utility model relieves the worry of users.
Description
Technical field
The utility model relates to a kind of gas heater air inlet opening/shutting controller, relates to a kind of gas heater simultaneously.
Technical background
Present gas heater relies on the unlatching of an aqueous vapor interstage valve control burnt gas valve, and its structure as shown in Figure 1.After cold water enters water heater from cold water inlet 1, arrive aqueous vapor interstage valve 2, utilize the pressure differential pressure of water to back down spool valve open.Behind the valve opening, combustion gas enters burner from air inlet, by the automatic ignition device combustion gas is lighted.Because the frame for movement be made up of assemblies such as springs of aqueous vapor interstage valve, the proper reset when guaranteeing the correct opening and closing of valve requires spring that certain intensity is arranged, and the requirement of this requirement and valve opening sensitivity is a contradiction.So existing gas heater has certain requirement to hydraulic pressure or differential water pressures, have only when the hydraulic pressure at cooling water inlet place reaches certain value, just might back down spool with valve open, make combustion gas enter the combustion chamber.This structure is used to the user and is put to no little inconvenience, and the dwelling house that hydraulic pressure is little can not use this constructed products, and the user of gas heater has been installed, because seasonal low hydraulic pressure or water concentrate the low hydraulic pressure that causes all may influence use.
Summary of the invention
Even the purpose of this utility model provides and a kind ofly also can make gas heater normally start the opening/shutting controller of sparking under low hydraulic pressure situation; The purpose of this utility model also is to provide a kind of gas heater that adopts this opening/shutting controller.
For achieving the above object, the utility model adopts following technical scheme: a kind of gas heater air valve automatic open close control device, comprise intake valve, it is characterized in that, described intake valve is a magnetic valve, the electric control end of magnetic valve is connected with the output of controller, and the water flow sensing unit output that the input of controller is contained on the water inlet pipe when using is connected.
Described controller is made up of signal processing circuit and gauge tap, the output of the input water receiving flow sensor of signal processing circuit, and the output of signal processing circuit is connected with gauge tap.
Between signal processing circuit and gauge tap, also be connected to drive circuit.
Described signal processing circuit is a single-chip microcomputer, and drive circuit is a triode, and gauge tap is a relay.
Water flow sensing unit can adopt tongue tube, wherein a kind of near switch, mistor, Hall element or electronic flowmeter.
The utility model also provides a kind of gas heater, comprise the air valve opening/shutting controller, the intake valve of this control device is a magnetic valve, and the electric control end of magnetic valve is connected with the output of controller, and the input of controller is connected with water flow sensing unit output on being contained in water inlet pipe.
Described controller is made up of signal processing circuit and gauge tap, the output of the input water receiving flow sensor of signal processing circuit, and the output of signal processing circuit is connected with gauge tap.
Between signal processing circuit and gauge tap, also be connected to drive circuit.
