Abstract
The utility model relates to an interlock switch that opens a water valve with low water pressure for a water heater, which is characterized in that a water inlet of a valve body is provided with a water inlet pipe that is vertical to the valve body, and the water inlet pipe is communicated with the water inlet; the interlock switch also comprises a water floating magnetic absorption device that consists of a water floating cylinder and a suspension magnet; the water floating magnetic absorption device is arranged inside the water inlet pipe, and the suspension magnet is opposite to the axial end wall on the water outlet end of the water inlet pipe; the interlock switch also comprises a micro switch that is fixed on the valve body, and a pressing plate of the micro switch is opposite to the axial end wall plate, and the pressing plate is provided with a plate magnet with the same polarity of the suspension magnet; the suspension magnet is matched with the plate magnet. Adopting the above structure, the water inlet pipe, the suspension magnet and the water floating cylinder are uneasy to be damaged, thereby having long service life; under the condition of low water pressure, the water can overcome the gravity of the water floating cylinder and the suspension magnet, so that the water floating cylinder and the suspension magnet can be floated so as to be interacted with the plate magnet on the pressing plate. Therefore, the interlock switch not only can be opened at the low water pressure, but also is free from damaging parts and has long service life.
Description
Technical field
The utility model relates to the device that water heater is used, and especially a kind of water valve connects moving switch.
Background technology
Present prior art, the aqueous vapor interstage valve that one water heater is used comprises water valve, connector, elastic sealing strip and is positioned at the microswitch of connector, the control stick of microswitch is positioned at the connector membranous disc, elastic sealing strip is between connector membranous disc and water valve membranous disc, there is the inlet opening at center at the water valve membranous disc, the water valve membranous disc an apopore that communicates with the water valve inner chamber radially arranged, on the inlet opening, be equipped with one, axle cooperates with interporal lacuna, and there is disk at the two ends of axle.During use, elastic insulated impeller-hub moves opens microswitch.Existing problems are: complex structure, and elastic insulated is consumable accessory, service life is short.
Summary of the invention
The purpose of this utility model is: provide a kind of low hydraulic pressure of water heater to start the water valve linked switch, it can not only hang down the hydraulic pressure startup, and does not have consumable accessory, long service life.
The utility model is achieved in that a kind of low hydraulic pressure of water heater starts the water valve linked switch, comprise water valve, water valve is made of valve body, spool and valve rod, on the radial wall of valve body, delivery port is arranged, there is water inlet the lower end of valve body, and its special character is: the water inlet of valve body is provided with one and communicates with water inlet with vertical water inlet pipe, the water inlet pipe of valve body; Comprise that also water floats the magnetic device, the floating magnetic device of described water is made of a water floating drum, suspension magnet, and suspension magnet and water floating drum are fixedly connected; The floating magnetic device of water is positioned at water inlet pipe, and suspension magnet is relative with the axial end wallboard of the water side of water inlet pipe;
Also comprise the microswitch that is fixed on the valve body, the pressing plate of microswitch is relative with the axial end wallboard, and the plate magnet with the suspension magnet same polarity is arranged on the pressing plate; Suspension magnet cooperates with plate magnet.
The low hydraulic pressure of described water heater starts the water valve linked switch, and its special character is: described microswitch is a microswitch of often opening.
The low hydraulic pressure of described water heater starts the water valve linked switch, and its special character is: described water side wallboard is a plug.
The low hydraulic pressure of the utility model water heater starts the water valve linked switch, owing to adopt such structure, water inlet pipe, suspension magnet and water floating drum, not fragile, long service life; Under the situation of low hydraulic pressure, water just can overcome the gravity of water floating drum and suspension magnet, and water floating drum and suspension magnet are floated, and with pressing plate on the interaction of plate magnet.Start so it can not only hang down hydraulic pressure, and do not have consumable accessory, long service life.
