Description

Oxygen gas stove control valve

The utility model relates to a fluid control valve with a cock, in particular to an oxygen-increasing gas stove control valve.

At present, the stove that uses combustible gas as fuel generally adopts a fluid control valve with a cock to adjust the firepower of the stove by controlling the flow rate entering the combustion head. There are two corresponding channels on the valve body and the valve core, one is the ignition gas channel, and the other is the combustion head gas channel. When the cock is turned, the ignition gas is connected, the electronic ignition power is connected, and then the combustion head gas channel is connected. On, the gas stove is ignited, and the ignition channel is closed. Continue to rotate the cock, the gas passage hole will be enlarged, the gas supply volume will gradually increase, and the firepower of the combustion head will also gradually increase. The oxygen required for the combustion of the combustion head depends entirely on natural supply. When the gas supply is large, the fuel is often incompletely burned due to insufficient oxygen supply, which not only pollutes the environment and cookers, but also affects the increase and concentration of output. At the same time, the gas stove seems to have insufficient firepower. Generally, the combustion head of a gas stove is composed of a central fire head and a ring-shaped outer firearm.

The purpose of this utility model is to provide a control valve for an oxygen-increasing gas stove. The control valve can make the central fire head and the outer firearm burn separately, and can also make the two burn at the same time; At the same time, the power is turned on, so that the fan located at the center fire head is started to supplement oxygen for the combustion head. energy.

In order to achieve the above purpose, the utility model adopts the following design scheme: the valve body of the oxygen-increasing gas stove control valve is provided with an ignition air passage, an outer fire air passage, and an inner fire air passage, and the air holes in the valve core chamber of the three air passages are axially arranged. Separated on the top, the outer circle of the plug-type spool is provided with an ignition air supply groove, an outer fire air supply hole and an inner fire air supply hole. The starting end of the valve core and the inner fire supply hole are in the opposite position on the outer circle of the valve core. The outer fire supply hole extends along the outer circle to 145 degrees to 150 degrees in a long strip shape. The outer air supply hole and the inner fire supply hole are directly connected to the main valve The air chambers are connected, and the ignition air supply tank is provided with air holes to communicate with the main air chamber; the valve body is equipped with a push switch, and an elastic pressure plate is installed in front of the switch button, and a fan-shaped pick is installed on the valve core rod, which is connected to the elastic pressure plate. match.

The utility model oxygen-increasing gas cooker control valve, the outer fire gas passage is connected with the ring-shaped outer firearm, the inner fire gas passage is connected with the central fire head, and the pressure switch on the valve body is connected with the fan arranged beside the central fire head by wires and connected with the power supply. connected. When you need to use the gas stove, press the adjustment knob at the outer end of the valve core lever, the ignition gas supply groove is connected to the ignition gas channel, and the electronic igniter ignites the gas; at the same time, the external fire supply gas hole is connected to the external fire gas channel , the ring-shaped outer firearm is ignited, and the firepower is low fire at this time, the first combustion method; when the knob is turned to the left to 110 degrees, the inner fire supply air hole and the inner fire air channel, the outer fire supply air hole and the outer fire air channel are simultaneously connected, At this time, the center fire head and the outer firearm are ignited at the same time; at the same time, the fan-shaped pick is rotated to the front of the elastic pressure plate of the press switch, and the pressure plate and the switch button are squeezed. At this time, the fan power is turned on and oxygen is supplied to the center fire head. When the firepower of the stove is at its peak, the second combustion method is used. When the knob continues to be turned to 170 degrees, the air supply hole of the outer fire and the air passage of the outer fire are cut off, the outer fire (outer firearm) is extinguished, and the center fire burns. At this time, the firepower is The third combustion method with medium firepower; reversely turn the knob to ignite the external fire, return to the second combustion mode, turn the knob again, the paddle is disengaged from the elastic plate of the switch, the power is cut off, and the central fire goes out at the same time, and the external firearm continues to burn back to Go to the first combustion mode; when the knob is reset, all three air passages are cut off, and all flames are extinguished. Under the control of this control valve, the central burner and the outer burner of the gas stove can be burned separately, and the two can be burned at the same time, producing three combustion modes and three different levels of firepower. At the same time, the valve can be controlled at the center When the burner is burning, start the fan next to the center burner to supply oxygen to it, so that it can generate greater firepower than ordinary gas stoves, meet the needs of cooking, and at the same time make the fuel burn completely, reduce environmental pollution and save energy.

Below in conjunction with accompanying drawing, the utility model is further described.
