Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a gas stove used for gas appliances for kitchens, etc.

(Prior Art and Problems) Generally, such a gas tank is a combination of a solenoid valve as a safety device and a gas tank or valve as the original gas tank. However, in the past, these devices were operated using two operating axes, each with a corresponding one, which resulted in a complex structure, making manufacturing and repair difficult, as well as being large, heavy, and expensive. It has a number of drawbacks, such as:

The present invention solves the above-mentioned drawbacks of the conventional valve by configuring the valve body of a solenoid valve and the original valve body to be operated by a common single operating shaft. The present invention will be described in detail below based on examples.

(Means for solving the problem) Reference numeral 1 is a Kotuku main body, and the Kotuku main body 1
A gas inlet side valve chamber 3 and a gas outlet side valve chamber 4 are provided which are communicated through a passage 2, and valve seats 5 and 6 are provided on the downstream side of the valve chambers 3 and 4, respectively. Code 7 is the gas inlet,
8 is a gas outlet. Therefore, the gas inlet side valve chamber 3 is provided with a solenoid valve 11 that brings the valve body 9 into contact with the valve seat 5 by the spring force of a spring 10, and the valve body 9 can be freely operated from the outside of the cock body 1. Operation axis 12
is slidably provided in the Kotoku main body 1 through the gas outlet side valve chamber 4, and a valve body 13 is brought into contact with the valve seat 6 of the gas outlet side valve chamber 4. The operating shaft 12 is provided at a position where it can come into contact with the valve seat 6 when it is away from the valve body 9, and the operating shaft 12 is configured to move only forward and backward.
In addition, the code|symbol 14 is a sealing member.

(Function) With the above configuration, the operation of the present invention will be explained as follows along with an example of how to operate the gas appliance. First, FIG. 1 shows the state when the gas appliance is not in use, and at this time both the valve bodies 9 and 13 are in contact with the corresponding valve seats 5 and 6, and the valves are closed. When using the gas appliance, the operating shaft 12, which only moves forward and backward, is moved to the left in the figure by a suitable operating mechanism. Then, due to the movement of the operating shaft 12, the valve body 13 first separates from the valve seat 6 and becomes open, and then the end of the operating shaft 12 comes into contact with the valve body 9 and pushes it against the spring force of the spring 10. As the valve body 9 moves, the valve body 9 separates from the valve seat 5 and enters the open state shown in FIG. 2, so that gas can flow from the gas inlet 7 to the gas outlet 8 and be supplied to the gas burner. The gas burner can be ignited by operating an appropriate ignition mechanism before and after this operation. Due to this ignition, the electromagnet 15 is activated by excitation by a thermocouple or the like, and when the solenoid valve 11 becomes able to maintain its open state, the operation shaft 1 is activated.
2 to the right in the figure, so that its end is located downstream of the valve seat 5, and the valve body 13 is further away from the valve seat 6, as shown in FIG. By stopping and holding in this position, the ignition operation of the gas burner is completed. As above, the operation axis 12
The operating mechanism for moving and stopping is appropriate. In the above state, if the gas burner goes out for some reason, the electromagnet 15 will no longer be energized and the valve body 9 will come into contact with the valve seat 5 due to the spring force of the spring 10, causing the state shown in Fig. 4 to occur. As shown, the valve is closed and the solenoid valve 11 can fulfill its function as a safety device.

Next, even if the electromagnet 15 is no longer excited due to the operation of a timer or the like, the solenoid valve 11
The valve is closed and the gas burner can be extinguished. After that, when the operating shaft 12 is moved to the right, the valve body 13 comes into contact with the valve seat 6, and the valve is in the closed state, so that it can fulfill its function as an original valve. It should be noted that the operation of the gas appliance corresponding to the operation of the present invention described above is merely an example, and such operation and its mechanism are appropriate. For example, extinguishing the gas burner as described above may be accomplished by moving the operating shaft 12 to the right and closing the valve on the former side. In this case, the solenoid valve 11 is closed by extinguishing the gas burner.

(Effect of the invention) As described above, the present invention completely fulfills both the function of the solenoid valve as a safety device and the function of the original valve as before, and the valve body can be operated by a common single operation. Since it can be operated with a shaft, it is easy to operate and can be operated with one touch.The simple structure also makes it easy to manufacture and repair.Moreover, it is smaller and lighter in weight than before. It has many features such as being able to be constructed at low cost. In addition, since the operating shaft only moves forward and backward, there is no error in operation, and the two valve bodies ensure safety in two stages.
