In a kitchen range, a gas valve is a valve body for manually adjusting and controlling the on-off of gas and adjusting the size of the gas, and generally comprises a shell, a valve core, a valve rod, a microswitch, an electromagnetic valve and other additional devices. The main working principle of the gas valve is as follows: the gas enters from the gas inlet of the gas valve, firstly passes through the electromagnetic valve, then enters the valve core, and finally is communicated with the gas outlet of the gas valve through the side opening of the valve core, thereby realizing the gas supply for the kitchen range. The communicating area of the side opening of the valve core and the gas outlet of the gas valve can be changed, and the valve core is rotated to adjust the gas flow.
The current ignition process of the gas valve is as follows: the valve rod on the manual gas valve that pushes down, the valve rod passes through link mechanism and backs down the solenoid valve and keeps the state of pushing down, the case in the gas valve is passed through to the gas, rotatory valve rod, the valve rod drives the case rotation and makes the side opening and the gas valve gas outlet intercommunication of case, give the cooking utensils air feed, the button of micro-gap switch can be triggered to the valve rod of pushing down simultaneously, make micro-gap switch signals to give pulse controller, control ignition needle discharges, thereby realize the effect of igniteing, the thermocouple produces the thermoelectromotive force under the effect of flame, make the solenoid valve maintain the actuation state.
The solenoid valve that uses at present is thermocouple formula solenoid valve, it completely backs up the solenoid valve to need the user to push down the knob earlier on to the end, make the movable iron core and the quiet iron core of solenoid valve contact, the thermocouple produces the thermoelectromotive force under the effect of flame, thereby the thermoelectromotive force makes the solenoid valve produce magnetic force and maintain the actuation state of solenoid valve, current structure leads to the user to hardly perceive whether oneself pushes down the knob and puts the solenoid valve top in place, just loose the hand can cause the solenoid valve to keep the actuation state failure when the user does not put the solenoid valve top in place, thereby lead to the ignition failure, bring not good ignition experience for the user.
