Embodiment Construction

[0045] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] like figure 1 , figure 2 , image 3 The gas stove cock valve shown includes a valve body 1 , a valve core 2 and a valve stem 3 . The inside of the valve body 1 is provided with an air inlet hole (omitted in the figure), a solenoid valve hole 9 and a cock hole 24 matched with the valve core 2, and a solenoid valve 5 is arranged inside the solenoid valve hole 5 and passes through the accommodating cavity 6 and the cock hole. 24 communicates with each other, and a lever mechanism 7 for opening the solenoid valve 5 is provided inside the accommodating chamber 6 , and the valve stem 3 penetrates through the valve core 2 and abuts against the lever mechanism 7 .

[0047] Different from the prior art, the valve rod 3 of the present invention is a two-stage type, which is divided into a switch rod 33 and a lower press...

Abstract

The invention discloses a thermoelectric type flame-out protection plug valve of a gas stove and a gas stove. The plug valve of the gas stove comprises a valve body, a valve core and a valve rod, wherein an air inlet hole, an electromagnetic valve hole and a plug valve hole matched with the valve core are arranged in the valve body, the air inlet hole is communicated with the electromagnetic valve hole, an electromagnetic valve is arranged inside the electromagnetic valve hole, the inner side of the electromagnetic valve hole is communicated with the plug valve hole through a containing cavity, and a lever mechanism used for starting the electromagnetic valve is arranged in the containing cavity; and the valve rod penetrates through the valve core to abut against the lever mechanism, the valve rod is in a two-section type and comprises a switch rod and a downward-pressing rod, one end of the switch rod is arranged outside the valve body, one end of the switch rod penetrates through the valve body, is matched with the valve core along the axial direction in a sliding mode and is positioned in a rotatable mode, the switch rod is provided with a rotary locking piece used for being matched with the gas stove, the downward-pressing rod penetrates through the valve core, one end of the downward-pressing rod abuts against the lever mechanism, the other end of the downward-pressing rod is in linkage with the switch rod through a valve rod spring, and the limit distance of the rotary locking piece for the switch rod is larger than a limit displacement produced when the downward-pressing rod pushes the lever mechanism. The gas stove comprises a shell body and the plug valve of the gas stove, wherein the plug valve is installed on the shell body.

Description

technical field [0001] The invention relates to a valve, in particular to a thermoelectric flameout protection plug valve for a gas stove and a gas stove. Background technique [0002] The gas stove cock valve is the core component of the household gas stove. The existing mechanical gas stoves are all ignited, adjusted the firepower and extinguished through the cock valve. The quality of the cock valve determines the quality of the stove. [0003] In order to achieve the purpose of flameout protection in the existing gas stove cock valve, a solenoid valve hole is provided between the air inlet hole and the cock hole, and a solenoid valve connected to an external thermocouple is arranged in the solenoid valve hole. When the thermocouple does not detect the flame, the rubber ring at the bottom of the solenoid valve will close the solenoid valve hole, so that the gas cannot enter the cock hole, which can prevent the gas from leaking. When the thermocouple detects the flame, th...
