Abstract

The invention provides a gas plug valve. The gas plug valve comprises a valve body. The valve body is internally provided with a solenoid valve hole forming a part of a gas inlet passage, a shifting fork cavity and a through hole communicating the solenoid valve hole with the shifting fork cavity. A solenoid valve used for controlling opening and closing of the gas inlet passage and a shifting fork used for opening the solenoid valve to open the gas inlet passage when the plug valve is turned on are mounted in the solenoid valve hole and the shifting fork cavity correspondingly. The solenoid valve is provided with a telescopic switching assembly. The shifting fork comprises a rotary shaft and shifting levers can rotating around the rotary shaft. A transmission assembly is arranged betweenthe solenoid valve and the shifting fork. The first shifting lever rotates to push the switching assembly through the transmission assembly. The transmission assembly comprises a guide part capable ofsliding in the through hole and a spring capable of being compressed when connected with the guide part for transmission. According to the gas plug valve, the spring is arranged on a transmission path on the long shifting lever side and is relatively easy to arrange. The gas plug valve is convenient to debug and install. Besides, gas leakage of the plug valve can be prevented.

Description

technical field [0001] The invention relates to a gas cock valve, in particular to a gas cock valve capable of preventing flameout by hand release. Background technique [0002] In order to prevent the stove from extinguishing after the knob is loosened, some plug valves have a spring on the transmission path between the valve stem and the solenoid valve, so that the unlocking stroke of the valve stem is greater than the stroke of the solenoid valve, ensuring that the solenoid valve is already closed when the knob is turned. Pull in to avoid ignition failure. [0003] For example, CN10258866 discloses a gas stove valve body, which includes a shell and a valve core. A valve needle is inserted in the valve core. There is a knob rod above the valve needle. The other end of the push rod has a push arm against one end of the solenoid valve. When the knob rod is pressed down, the child lock on the valve body is released and the gas pipeline is rotated. When the knob rod is presse...
