Description

Technical Field

[0001] This utility model relates to a valve, and more particularly to a gas stove valve. Background Technology

[0002] A gas valve is a new type of safety device for gas pipeline projects. It is used to cut off, connect, and regulate the gas in the pipeline, and has good control characteristics and sealing performance.

[0003] Gas stoves use gas valves to control the opening and closing of the gas stove and adjust the flame intensity. Existing gas valves generally have only one channel, from the gas inlet, valve chamber, inner hole of the valve core, and gas hole of the valve core to the gas outlet. This can only achieve the ordinary flame function for household use, and does not have the high flame function used in restaurant cooking. It cannot achieve both ordinary and high flame functionality. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a gas stove valve.

[0005] This utility model provides a gas stove valve, including a valve seat 1 and a mounting base 2 connected to the bottom of the valve seat 1. The valve seat 1 has a valve cavity, and the side wall of the valve cavity has an air inlet 11, an adjustment channel 15, and two air outlets 12. The adjustment channel 15 is connected to one of the air outlets 12. A valve core 5 is rotatably disposed in the valve cavity. The valve core 5 has an interconnected inner hole 52, a second air hole 54, and two first air holes 53. The inner hole 52 is connected to the air inlet 11. A valve stem 4 is disposed at the end of the valve core 5. The valve stem 4 is used to drive the valve core 5 to rotate and make the first air holes 53 connect to the air outlets 12 respectively. At the same time, the second air hole 54 is blocked by the valve cavity or connected to the adjustment channel 15.

[0006] Furthermore, the two air outlets 12 and the adjustment channel 15 are located on the same plane, and the two air outlets 12 are arranged symmetrically on the left and right.

[0007] Furthermore, the bottom of the valve seat 1 is provided with a protrusion 16, the adjustment channel 15 is disposed in the protrusion 16, and the bottom of the protrusion 16 is screwed with an adjustment screw 6.

[0008] Furthermore, the two first air holes 53 are arranged symmetrically front and back, and the first air hole 54 and the second air hole 54 on the rear side are vertically corresponding.

[0014] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0015] See Figures 1-5This utility model provides a gas stove valve, which includes a valve seat 1 and a mounting base 2 connected to the bottom of the valve seat 1. A micro switch is installed on the mounting base 3. The micro switch is existing technology. A valve cavity is provided inside the valve seat 1. The side wall of the valve cavity has an air inlet 11, an adjustment channel 15, and two air outlets 12. The two air outlets 12 and the adjustment channel 15 are located on the same plane. The two air outlets 12 are symmetrically arranged on the left and right. The adjustment channel 15 is connected to one of the air outlets 12. A valve core 5 is rotatably arranged inside the valve cavity. The valve core fits into the valve cavity. The valve core 5 has an interconnected inner hole 52, a second air hole 54, and two first air holes 53. The inner hole 52 is connected to the air inlet 11. A valve stem 4 is provided at the end of the valve core 5. The valve stem 4 is used to drive the valve core 5 to rotate and make the first air holes 53 connect to the air outlets 12 respectively. At the same time, the second air holes 54 are blocked by the valve cavity or connected to the adjustment channel 15. Press and rotate the valve stem. The valve stem drives the valve core to rotate. The first air hole of the valve core connects to the air outlet. At this time, the second air hole is blocked by the valve cavity. The gas enters the air outlet through the air inlet, valve cavity, inner hole, and first air hole, which is the gas flow rate in the normal flame state. This continues until the first air hole separates from the air outlet. Then, continue to rotate the valve stem. The first air hole connects to the air outlet again. At the same time, the second air hole connects to the regulating channel. The gas on one side enters from the dual channels. The first channel is the air inlet, valve cavity, inner hole, first air hole, and air outlet. The second channel is the air inlet, valve cavity, inner hole, second air hole, regulating channel, and air outlet. The gas on the other side still enters from the first channel, which is the gas flow rate in the high flame state.

[0016] The bottom of the valve seat 1 is provided with a protrusion 16, and the adjustment channel 15 is disposed inside the protrusion 16. An adjustment screw 6 is screwed to the bottom of the protrusion 16. The adjustment screw can adjust the air flow of the adjustment channel or block the adjustment channel.

[0017] See Figure 2 , Figure 5 Two first air holes 53 are symmetrically arranged front and rear, and the rear first air hole 54 and second air hole 54 are vertically corresponding. The two first air holes can connect to the two air outlets separately and simultaneously. The second air hole connects to the adjustment channel while the first air hole connects to the air outlet.

[0018] The valve core 5 has a groove 51 at its top end for inserting the end of the valve stem 4. The mounting base 2 has a movable groove 21 for the end of the valve stem 4 to abut and move. A limiting block 22 on the inner wall of the movable groove 21 limits the movement of the end of the valve stem 4. When the valve stem is pressed and rotated, its end extends into the groove and passes the limiting block. The valve stem rotates within the movable groove, and the end of the valve stem rotates the valve core through the groove. After the valve stem is released, it moves downwards and returns to its original position under the action of a spring, with its end resting against the movable groove.

[0019] The movable angle of the movable slot 21 is 270 degrees. As the valve stem and valve core rotate to 90 degrees, the gas gradually increases. As the valve stem and valve core rotate from 90 degrees to 180 degrees, the gas gradually decreases until it is closed. When the valve stem and valve core rotate from 180 degrees to 270 degrees, the gas on one side enters from the dual channels, and the gas on the other side enters from the first channel, which is the high flame state.

[0020] The valve chamber consists of an upper chamber 13 connected to a lower chamber 14 via a central connecting hole. A flameout protection device 2 is installed in the upper chamber 13. This device comprises a thermocouple and a solenoid valve. The thermocouple acts as a sensor; upon receiving heat, it transmits the information to the solenoid valve in the form of an electric potential. The solenoid valve then attracts the blockage block to open the gas orifice, ensuring normal combustion of the gas stove. When the flame is accidentally extinguished, the heat is gone, and the thermocouple transmits a signal to the solenoid valve. The solenoid valve then releases the blockage block, and the blockage block, under its own elastic force, resets to block the gas orifice, thus cutting off the gas supply. This flameout protection device is existing technology. A push rod 7, passing through the valve core 5 and used to push the flameout protection device 2, is installed at the top of the valve stem 4. A spring connecting the valve core 5 and the push rod 7 is fitted around the push rod 7. The spring causes the push rod and valve core to move away from each other, with the valve core fitting against the valve cavity. The push rod causes the end of the valve stem to abut against the movable groove. Pressing up and rotating the valve stem causes the valve stem to move upward with the push rod. The push rod pushes open the block of the flameout protection device, allowing the upper and lower chambers to connect. Gas enters the gas stove from the chamber and the gas outlet. After the gas stove ignites, the solenoid valve will attract the block (in case of accidental flameout, the solenoid valve will release the block to block the gas hole). After releasing the valve stem, the push rod returns to its original position with the valve stem.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
