It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-6, the integrated gas appliance control valve of the present invention comprises a self-priming solenoid valve 1, a body 2, a valve core 3, a knob 4 and a controller (not shown in the figure). The gas appliance burner is provided with a flame ion probe (not shown).

As shown in fig. 1-6, the self-priming solenoid valve 1 is a self-priming solenoid valve including a sealing member 12 and a spring 11.

As shown in fig. 1-6, the body includes a gas channel disposed in the body, an inlet channel 21 and an outlet channel 22 of the gas channel, the inlet channel includes an inlet end surface 23, and the gas inlet 9 and the gas outlet are disposed on the body.

As shown in fig. 1-6, the valve core 3 is rotatably disposed in the body 2, the outer wall of the valve core 3 clings to the inner wall of the body 2, and the valve core comprises: a central hole 31 arranged in the valve core and a vent hole 32 arranged on the wall surface of the valve core, wherein the central hole 31 is communicated with the air inlet channel 21, and when the valve core 3 rotates, the vent hole 32 can be controlled to be communicated with the air outlet channel 22.

As shown in fig. 1 to 6, a self-priming solenoid valve 1 is connected to a body 2, and a sealing element 12 of the self-priming solenoid valve 1 is used for closing or opening an air inlet end face 23.

The gas 6 sequentially passes through a gas inlet 9, a gas inlet end face 23, a gas inlet channel 21, a gas outlet channel 22, a valve core central hole 31, a valve core vent hole 32 and a nozzle hole 81 to form a gas channel, and the gas 6 flows to the combustor through the nozzle hole 81 in the gas channel to be ignited and combusted.

As shown in fig. 1-6, the knob 4 includes a knob stem 41, under which is located a push rod 42, which knob 4, when rotated, causes the cartridge 3 to rotate. The push rod 42 is hollow and sleeved on the knob rod 41, and is fixed up and down by two clamp springs 43, can move up and down along with the knob rod 41, and does not rotate along with the knob rod 41. The valve core 3 is provided with a clamping groove 35, the tail end of the knob rod 41 is inserted into the upper end of the valve core, and the purpose is to drive the valve core 3 to rotate anticlockwise when the knob rod 41 rotates, so that the valve core vent hole 32 is communicated with the nozzle hole 81, and the purpose of gas channel communication is achieved.

As shown in fig. 1-6, the sealing spring 34 presses the valve core 3 tightly to make it tightly contact with the conical surface of the control valve body 2, and at the same time, the clamp spring 43 limits the position, and the valve cover 33 is pressed upward to make the knob rod 41 pressed downward, and then the hand is released to be able to upwards automatically reset.

As shown in fig. 1 to 6, a process plug 7 is installed on the control valve body 2, and is used for ensuring that the fuel gas 6 can enter the central hole 31 of the valve core through the gas inlet channel 21 as required in structural process. The process plug 7 may be a bolt, cylinder or other shape.

When the self-suction type gas valve is used, the knob 4 is pressed down, the knob rod 41 is driven by the knob 4, the push rod 42 is pushed down to touch the micro switch 5, an electric signal is sent to the controller, the self-suction type electromagnetic valve 1 is driven by the controller to suck, the sealing element 12 is separated from the gas inlet end face 23, meanwhile, the knob 4 rotates anticlockwise by 90 degrees, and gas 6 flows through the gas inlet channel 21, the gas outlet channel 22, the valve core central hole 31, the valve core vent hole 32 and the nozzle hole 81, so that the gas channel is opened. When the knob 4 is not pressed down and rotates 90 degrees anticlockwise, the self-suction electromagnetic valve 1 is not opened at the moment, the sealing element 12 is tightly attached to the air inlet end face 23 under the action of the elastic force of the spring 11, and the gas 6 only stays in the gas inlet 9 of the control valve body 2.

After the fuel gas 6 flows out and is ignited, the flame ion probe is simultaneously burnt, the flame ion probe sends an electric signal to the controller, at the moment, the knob 4 can be loosened, the push rod 42 is reset upwards along with the knob rod 41, the micro switch 5 is immediately disconnected, and the self-suction electromagnetic valve 1 is maintained to work by the controller. When the knob 4 is reset to shut off fire or flame is accidentally extinguished, the electric signal of the flame ion probe disappears, the controller sends out an instruction, the self-suction electromagnetic valve 1 is simultaneously closed, and the sealing element 12 is reset to be tightly attached to the air inlet end face 23 under the elastic force action of the spring 11, so that the fuel gas is ensured not to leak.

When a fan of a blowing type gas appliance (such as a blowing type combustor disclosed in Chinese patent No. CN201710132323. X) breaks down, when a mechanical conical surface sealing valve and a hand-push type low-current electromagnetic valve are adopted, a gas channel is pushed by a hand to open the electromagnetic valve, a controller does not send an instruction to work for the electromagnetic valve, and at the moment, gas can flow out of a nozzle.

As an embodiment of the utility model, the combustor is the blowing type combustor, and this blowing type combustor includes the fan, and when the fan broke down and did not rotate, the signal of telecommunication was given to the controller, this moment the controller control from inhaling the formula solenoid valve and closing.
