Embodiment 1

[0060] This embodiment discloses a solenoid valve, such as Figure 1-3As shown, the electromagnetic valve includes an electromagnetic generator 10 , a piston rod 20 , an elastic member 30 and a connecting member 40 . Among them, the electromagnetic generator 10 is used to generate an electromagnetic field. The piston rod 20 is movably inserted in the electromagnetic generator 10 , and the movable insertion means that the piston rod 20 can extend and retract relative to the electromagnetic generator 10 . The elastic member 30 is used to provide a first force to the piston rod 20 along a first direction, and the first direction is a direction in which the piston rod 20 protrudes from the electromagnetic generator 10 . The connecting piece 40 is arranged on the end of the piston rod 20 away from the electromagnetic generator 10 , the connecting piece 40 is made of functional material, and the connecting piece 40 can be switched between an initial state and an elastically deforme...

Embodiment 2

[0077] Such as Figure 4 As shown, this embodiment also provides a proportional valve assembly 50, which includes the solenoid valve in the first embodiment above. Wherein, when the connector 40 is in the initial state, the end of the piston rod 20 away from the electromagnetic generator 10 blocks the gas outlet of the proportional valve assembly 50; when the connector 40 is in an elastic deformation state, the end of the piston rod 20 away from the electromagnetic generator A gap for passing gas is formed between one end of 10 and the gas outlet.

[0078] Specifically, the gas outlet is provided with a closed end surface of the valve seat. When the connecting piece 40 is in the initial state, the end of the piston rod 20 away from the electromagnetic generating part 10 abuts against the closed end surface of the valve seat; when the connecting piece 40 is in an elastically deformed state , the piston rod 20 moves along the second direction relative to the electromagnetic gen...

Abstract

The invention discloses an electromagnetic valve, a proportional valve assembly and a water heater. The electromagnetic valve comprises an electromagnetic generation part, a piston rod movably inserted in the electromagnetic generation part, an elastic piece for providing first acting force in a first direction to the piston rod, and a connecting piece arranged at one end of the piston rod and produced by a functional material and capable of being switched between an initial state and an elastic deformation state, wherein the first direction is a direction of the piston rod extending out of the electromagnetic generation part; in the initial state, the piston rod extends out relative to the electromagnetic generation part; in the elastic deformation state, the connecting piece provides second acting force in a second direction to the piston rod; and the second direction is opposite to the first direction. The proportional valve assembly comprises the electromagnetic valve. The water heater comprises the proportional valve assembly. The connecting piece can provide initial pushing force to the piston rod to open the valve more reliably. Correspondingly, the proportional valve assembly and the water heater have an advantage of easily opening a gas outlet.

Description

technical field [0001] The invention relates to the field of gas water heaters, in particular to an electromagnetic valve, a proportional valve assembly and a water heater. Background technique [0002] Gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel to transfer heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. [0003] The basic working principle of the gas water heater is that cold water enters the water heater, flows through the water-gas linkage valve body, under the action of a certain pressure difference of the flowing water, pushes the water-gas linkage valve, and at the same time pushes the DC power supply micro switch to turn on the power and start the pulse ignition At the same time, open the gas transmission electromagnetic valve, and continue to automatically re-ignite through the pulse igniter until the ignition is successful and enters t...
