Description

Technical Field

The utility model relates to a gas valve technique, in particular to trigger long gas plug valve of stroke.

Background

The existing gas plug valve for the gas stove generally comprises a valve body, wherein the valve body is provided with a valve cavity, a plug cock is rotatably arranged in the valve cavity, a main shaft is pivoted on the valve body, a knob is connected on the main shaft, the plug cock is linked to rotate when the main shaft rotates, a communicating channel is formed in the plug cock, and after the plug cock rotates, an air inlet and an air outlet of the valve cavity are communicated through the communicating channel, so that air is supplied to the stove. In order to increase the safety function and prevent the gas leakage after the flameout of the furnace end, the existing gas plug valve is generally provided with a flameout protection device. The flameout protection device comprises a thermocouple and an electromagnetic valve, the thermocouple is installed at the position of the furnace end, one end of the thermocouple is close to the combustion position of the furnace end, the electromagnetic valve is installed on the valve body, a valve rod of the electromagnetic valve is provided with a plug, and the thermocouple is electrically connected with the electromagnetic valve. When the furnace end normally burns, thermocouple one end is heated, produces the thermoelectric voltage, and the thermoelectric voltage is the solenoid valve power supply, and the solenoid valve adsorbs the valve rod, and the jam is mentioned. When flame of the furnace end is accidently extinguished, the temperature difference voltage disappears, the electromagnetic valve is powered off, the valve rod is reset under the action of the spring in the electromagnetic valve, and the valve rod is ejected out and blocks a gas channel on the valve body, so that gas supply is cut off.

When the gas stove is just used, the burner is not combusted, the thermocouple cannot provide electric energy for the electromagnetic valve, and the gas channel is blocked and kept blocked. In order to solve the problems, an electromagnetic valve trigger rod is axially and movably arranged on the cock, when the main shaft rotates in the positive direction (the rotating direction for supplying gas by opening the gas cock valve), the main shaft is linked with the electromagnetic valve trigger rod to move forwards through a linkage mechanism, the electromagnetic valve trigger rod pushes the plug to move forwards, so that the plug does not plug a gas channel, and the gas can be output at a furnace end. When the main shaft of the gas plug valve rotates forwards, the ignition needle is synchronously driven to ignite, so that the ignition work of the furnace end is realized. After the furnace end is ignited, the thermocouple generates temperature difference voltage, and the electromagnetic valve keeps the valve rod in an adsorbed state through the temperature difference voltage, so that the gas channel can be kept in an open state all the time.

According to the existing gas plug valve, the rotation displacement of the main shaft is converted into the axial displacement through the linkage mechanism, and the linkage mechanism triggers the electromagnetic valve trigger rod to move forwards in the axial direction through the axial displacement, so that the electromagnetic valve is triggered through the electromagnetic valve trigger rod. In the gas plug valve, the stroke of the movement of the trigger rod of the electromagnetic valve is still insufficient, and the electromagnetic valve cannot be opened to a greater degree during ignition so as to supply more gas.

Referring to fig. 1 to 3, the valve body 100 is provided with a first cam structure 190, the main shaft 400 is provided with a matching portion 490 matched with the first cam structure 190, and the first cam structure 190 can convert the forward rotation motion of the main shaft 400 into the axial forward motion of the main shaft 400.

Specifically, the valve body 100 includes a main body 101 and a connecting frame 102 installed at one end of the main body 101, a through hole for the spindle 400 to pass through is formed in the connecting frame 102, the first cam structure 190 includes a plurality of protruding portions formed on the connecting frame 102 and perpendicular to the surface of the spindle 400, the matching portion 490 includes a pin shaft formed perpendicular to the spindle 400, and the pin shaft can slide through the protruding portions.

Specifically, the main shaft 400 is provided with a limiting structure to cooperate with the valve body 100 to form the above-mentioned movement margin, and the limiting structure includes a snap spring and a gasket.
