Description of the invention (2) "For solving the problem" The present invention is To solve this problem, if an operation shaft ′ supported by a gas valve body is rotated, the operation shaft is linked with the rotation of the operation shaft, and the cam plug in the gas valve body is moved in the axial direction. _The rod extending in the direction of the axis' line moves in the axial direction and is pushed by the rod to open a closed gas passage safety valve on the gas valve device, which is characterized in that a gas supply quantity is provided for regulating Needle valve, which adjusts the amount of gas passing through the space between the needle valve body and the valve seat that can freely move forward and backward to the valve seat formed in the gas passage, and presents a rotating body that rotates in conjunction with the operating shaft. It is rotatably mounted on the gas valve body, and forms a spirally extending cam surface on the rotary body and is embedded in the needle valve body. If the rotary body rotates, the needle valve body moves forward and backward to adjust the gas supply. Because the closed valve system rotates in conjunction with the operating shaft, when the closed valve reaches the position of the minimum opening circle, although the rotation of the closed valve cannot be stopped and only the operating shaft is rotated, but in the present invention, the system When the cam surface is shaped appropriately, and only when the needle shaft is rotated while the needle valve is stopped at the minimum opening state, the gas supply is reduced, the needle valve opening circle is prevented from being too small and the fire can be extinguished. Therefore, ‘the gas supply can be finely adjusted in the state of the smallest opening circle. In addition’, the needle valve does not move forward and backward, so it is not easy to rely on only one side to ensure smooth sliding. However, if the cam plunger is fitted to rotate in conjunction with the operation shaft, and the rotary body is fitted to rotate in conjunction with the cam stopper, it is possible to prevent the cam plunger from rotating. The body moves to the rotation direction of the cam plunger earlier, and the paper size that rotates in conjunction with the operating shaft is applicable to China National Standard (CNS) A4 (2) 0 X 297 mm.

The safety valve 3 shown in FIG. 1 is that the gas will not flow downstream of the safety valve 3 in the closed state, but if the lever 2 is moved to the right and the safety valve 3 is pushed to open it, the gas will flow downstream. A main valve 2a is installed in the middle of the stem 2. The stem 2 is provided with a potential to move to the left by a spring 4 inserted between the main valve 2a and the seat member 3a. The main valve shown in FIG. 1 The 2a system is in a closed state that is pushed against the valve seat id. The gas system does not flow downstream of the main valve 2a. However, if the rod 2 is moved to the right and the valve is opened, the gas will flow downstream. The gas valve body 1 is mounted on the needle valve body 5 above the first figure. Inside the needle valve body 5 is formed a gas passage 50 communicating with the gas outflow port lc of the gas valve body 1, and a through hole 51 communicating with the gas passage 50 and extending in the left-right direction. The through-hole 51 is inserted by the needle valve body 6 to be described later from an opening 5 1 a at the left end, and the gas passed from the gas outlet 1 c to the needle valve body 5 is inserted through the passage 50 from the right end of the needle valve body 5. The gas outlet 5a is sent to a burner (not shown). The needle valve body 5 is provided with a needle valve B. The needle valve B is formed by a paper rule.

In addition, the needle valve body 6 is provided with a O-ring 6a for sealing. In this way, since the closed state of the needle valve B is the minimum opening circle state, it is possible to prevent the needle valve opening circle from being too small and extinguish the fire, so that the fine adjustment of the gas supply amount in the minimum opening circle state is easy. In addition, according to the size of the throttling passage 6 (:, the gas supply amount in the state of the smallest opening ring can be set, so the gas supply amount in the state can be stabilized. In addition, 'the needle valve body 6 is not for rotation but The "forward and backward movement" makes it easy to ensure smooth sliding in a closed state.

If the operating shaft 13 is rotated to the left to the bottom as shown in FIG. 3, the lever 2 is pushed to the right and the main valve 2a is fully opened by the cam stopper 11 moving to the right. , The safety valve 3 is opened by being pushed by the lever 2, and the cam surface 8 b of the cam 8 that rotates to the left pushes the lever 6 b of the needle valve body 6 to the left, and the needle valve body 6 is fully opened, so that Gas corresponding to strong fire is supplied to the burner through the gas passage 50. In addition, "the cam plate 15 is rotated and the discharge switch (not shown) is turned on" to cause the burner to be ignited and heat a thermocouple (not shown) arranged near the burner. And by the temperature difference potential generated by the thermocouple until the safety valve 3 is kept in the open state, the operation knob 13 is continuously applied with a force to the left to rotate by the operation knob 17. After the safety valve 3 remains in the open state, releasing the leftward rotation force causes the claw portion 13b of the operating shaft 13 to be crimped to the guide plate 14 as shown in FIG. 4, and the gas valve device becomes as shown in FIG. The valve opening state shown in the figure. In this state, the claw portion 13b is not inconsistent with the 〇i4a, so that the operating shaft 13 is maintained at a rotatable paper size.

Description of the invention (8) Turn the state and keep the main valve 2a in the open state. In addition, the cam plunger 11 is pushed to the left by the lever 2, and the latch 18 is fitted into the narrow and wide portion 102 of the fitting groove 10. If the operation knob Π is rotated in this state, the operation shaft 13, the latch 18, the cam plunger 11, and the cam 8 are rotated, and the rod 6b of the needle valve body 6 is moved to the left and right by the cam surface 8b to adjust the needle valve body 6 degree of valve opening. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the note on the back before filling out this page). From the state shown in Figure 4, continue to rotate the operating shaft 13 to the right, so that the needle valve body 6 borrows the spring 7 On the other hand, the valve is pushed to the right and the valve opening degree is gradually decreased, and the valve seat 5b is closed. The closed state is the smallest open circle state, so that the least amount of gas is supplied to the burner. However, the cam surface 8b is fitted only in a direction in which the rod 6b of the needle valve body 6 is moved to the left, and when the operation of the needle valve body 6 is stopped, only the operation shaft 13 can be rotated to the right. Here, if only the operation shaft 13 is rotated further to the right from this state, the claw portion 13b of the operation shaft 13 and the cutout 14a will be finally made to coincide. In this way, the operation shaft 13 is pushed to the left by the spring 16, the claw portion 13 b is fitted into the gap I4 a ′, the operation shaft 13 is moved to the position shown in FIG. 1, and the main valve 2 a is brought into close contact with the valve seat. Id, the valve was closed, gas supply to the burner was stopped, and the burner was turned off. If the burner is turned off, the temperature difference and the potential energy generated by the thermocouple are reduced ', so that the safety valve 3 cannot be kept open and the valve is closed, and the entire gas valve device is returned to the closed state shown in FIG. 1. "Inventive effect" As described above, according to the present invention, the setting and adjustment of the gas supply amount can be easily performed.
