[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 are controlled by gas valves to turn the gas stove on and off and adjust the flame intensity. The existing gas valve adjustment screw is basically located at the bottom of the valve seat (on the same side as the valve stem). Due to the high integration and small size of the gas valve, and the fact that one side of the valve stem is the knob of the gas stove, it is not possible to drill a hole at the knob to easily turn the adjustment screw. Every time the adjustment screw is turned, the gas stove needs to be flipped up, which is inconvenient. Summary of the Invention

Detailed Implementation

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

[0015] See Figures 1-6 This utility model provides a gas stove valve, which includes a valve seat 1 and a mounting base 3 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. An air inlet 11 and an air outlet are opened on the side wall of the valve cavity. The air outlet branches into two paths, forming a first air outlet pipe 12 and a second air outlet pipe 13, respectively. The first air outlet pipe 12 and the second air outlet pipe 13 are located on the left and right sides of the valve cavity. The front end of the valve cavity is located on the side of the valve cavity. The wall has an adjustment channel 14 that communicates with the air outlet. An adjustment screw 6 is screwed to the front end of the valve seat 1. The adjustment screw can adjust the air flow of the adjustment channel or block the adjustment channel. 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 and a vent hole. The inner hole 52 communicates with 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, so that the vent hole communicates with the air outlet or the adjustment channel 14. Press and rotate the valve stem. The valve stem drives the valve core to rotate, and the vent hole of the valve core connects with the gas outlet until it closes. Gas enters the gas outlet through the inlet, valve chamber, inner hole, and vent hole. Then continue to rotate the valve stem. The vent hole of the valve core connects with the regulating channel. Gas enters the gas outlet through the inlet, valve chamber, inner hole, vent hole, and regulating channel, resulting in a stable low flame. The adjusting screw can adjust or block the gas flow of the regulating channel. The existing gas valve adjusting screw is basically located at the bottom of the valve seat (on the same side as the valve stem). Each time the adjusting screw is turned, the gas stove needs to be flipped up. The adjusting screw of this gas valve is located at the front of the valve seat (the adjusting screw is located below the gas stove). A hole is made at the top of the gas stove facing the adjusting screw, so the adjusting screw can be turned through the hole, which is simple and convenient.

[0016] A boss 15 is provided at the front end of the valve seat 1, an adjustment channel 14 is provided inside the boss 15, and an adjustment screw 6 is screwed to the front end of the boss 15.

[0017] See Figure 3 , Figure 4 , Figure 6 The vent includes a first vent 53 and a second vent 54 arranged front and rear. The first vent 53 is located above the second vent 54. The first vent 53 can be connected to the first vent pipe 12, and the second vent 54 can be connected to the second vent pipe 13 or the regulating channel 14. When the valve core rotates, the first vent connects to the first vent pipe, and at the same time, the second vent connects to the second pipe. The regulating channel is blocked by the valve cavity until the vent and the pipe are closed. Then, the second vent connects to the regulating channel, and the first vent and the first vent pipe are blocked by the valve cavity.

[0018] The valve core 5 has a groove 51 at its top for inserting the end of the valve stem 4. The mounting base 3 has a movable groove 31 for the end of the valve stem 4 to abut and move. The inner wall of the movable groove 31 has a limiting block 32 for limiting the end of the valve stem 4. When the valve stem is pressed up and rotated, the end of the valve stem extends into the groove and passes the limiting block. The valve stem rotates in the movable groove, and the end of the valve stem rotates the valve core through the groove. After the valve stem is released, the valve stem moves down and returns to its original position under the action of the spring, and the end of the valve stem abuts against the movable groove.

[0019] The movable angle of the movable groove 31 is greater than or equal to 170 degrees and less than or equal to 180 degrees. Preferably, the movable angle of the movable groove is 175 degrees.

[0020] The valve chamber consists of an upper chamber connected to a lower chamber via a central connecting hole. A flameout protection device 2 is installed in the upper chamber. 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.
