る構造とすることは容易でない。 Recently, gas solenoid valves have been widely used as on-off valves for gas appliances such as gas water heaters, gas baths, gas cookers, and gas stoves. For safety reasons, two solenoid valves are usually used in series, so that if one fails, the other stops the gas flow. However, the above-mentioned conventional solenoid valve has the disadvantage that it is expensive because two are used for safety reasons, and that the gas passage has many bends and connections. To solve this problem, two valves are slidably mounted on a valve rod driven by one plunger.
A solenoid valve for gas has been proposed in which each valve is closed and closed independently by a separate spring, and when the valve is opened, it is simultaneously opened by suction from a plunger. −
(See No. 100662). However, in the above-mentioned valve, when the valve rod and the valve are to be slid together, it is necessary to form a sliding hole in the valve, and the inner diameter of the sliding hole and the outer diameter of the valve rod must be precisely formed. 2 on the valve rod without sliding each valve.
When attaching two valves, the distance between the two valves must be precise. Furthermore, if one valve is fixed to the valve rod and the other valve is locked to the connecting rod without a sliding hole, the structure of the locking portion becomes complicated. In any of the above cases, it is not easy to create a structure that is easy to install and suitable for mass production.

給される。 FIG. 1 is a sectional view showing an embodiment of the present invention, and FIG. 2 is a detailed view showing the valve structure thereof. That is, the coil 3 is wound around the plunger 1 and the inner yoke 2, and the outside of the coil 3 is surrounded by the outer yokes 5 and 6 to form a magnetic path. A valve rod 4 is fixed coaxially to the tip of the plunger 1, and a first valve 7 is fixed to the tip of the valve rod 4. A connecting rod 4' is fixed to the first valve 7, and the tip of the connecting rod 4' is loosely fitted into the center of the second valve 8, and
It is locked to the second valve 8. The detailed structure of the second valve 8 will be described later. A case 9 is provided coaxially surrounding the valves 7 and 8, and the lower end of the case 9 in the figure is tightly fixed to the outer yoke 5. The case 9 constitutes a gas passage. Two annular protrusions 10 and 11 are provided on the inner periphery of the case 9, and a first seat surface 10 of each protrusion faces the valves 7 and 8.
a and the second seat surface 11a can be in airtight contact with the valves 7 and 8, respectively. That is, the valve 7 and the first seat surface 10a constitute a first valve part, and the valve 8 and the second seat surface 11a constitute a first valve part.
and constitute a second valve part. The valves 7 and 8 are pressed toward the seat surfaces 10a and 11a by the biasing forces of the springs 12 and 13, respectively, to close the gas flow path. Since the second valve 8 is loosely fitted onto the connecting rod 4' and can be slid slightly in the axial direction, it can be closed independently of the first valve 7. When the coil 3 is energized, the plunger 1 is attracted to the inner yoke 2 (the position shown in the figure), and the valves 7, 1 resist the biasing forces of the springs 12, 13.
8 away from the sheet surfaces 10a, 11a to open the gas flow path. When the gas flow path is opened, gas flows into the case 9 from the inlet on the left side in the figure, flows out from the outlet on the upper side in the figure, and is supplied to a gas appliance or the like (not shown).

ができる。 FIG. 2 is a detailed diagram showing an example of the structure of the second valve 8. As shown in FIG. That is, the valve 8 is composed of an elastic body part made of an elastic body such as rubber, which has a cylindrical body 8a and a flange part 8b, and a flange-shaped metal bulb holder 8c that abuts the lower surface of the flange part 8b. Ru.
In the cylindrical body 8a, a small diameter hole with an inner diameter d 1 is bored in the center of the lower part of the figure, and a large diameter hole with an inner diameter D 1 is bored in the inner part thereof. This large diameter hole is a hole that does not penetrate the valve 8. A small-diameter neck portion with an outer diameter d 2 is formed near the end of the connecting rod 4', and a large-diameter head portion with an outer diameter D 2 is formed at the tip end. The outer diameter D 2 of the large-diameter head is smaller than the inner diameter D 1 of the large-diameter hole and larger than the inner diameter d 1 of the small-diameter hole, and its height is smaller than the depth of the large-diameter hole by α 1 . . Therefore, the large diameter head of the connecting rod 4' is loosely fitted into the large diameter hole of the valve 8,
It can be slid by α 1 in the vertical direction. Further, the outer diameter d 2 of the small diameter neck of the connecting rod 4' is smaller than the inner diameter d 1 of the small diameter hole of the valve 8. Further, the length of the small diameter neck portion is longer than the length of the small diameter hole by α 2 and does not interfere with the stroke length α 1 of the large diameter head. The valve holder 8
The lower end of the cylindrical body 8a is fitted into the center hole c, and external force applied to the flange 8b or the rod 4'
Due to the force applied when the large-diameter head of the rod 4' is locked in the small-diameter hole of the valve 8, the cylindrical portion 8a formed of rubber or the like is deformed, causing the large-diameter head of the rod 4' to deform. Prevent it from slipping out. In addition, since the flange 8b of the elastic body is uniformly pressed by the biasing force of the spring applied from the lower surface of the valve holder 8c, the second seat surface 11a (the first (see figure) and close the valve.

磁弁を提供することができる。 The valve structure of this embodiment is easy to manufacture because the elastic body portion of the valve 8 can be formed from an elastic body such as rubber using a mold or the like, and can be manufactured suitable for mass production. The valve holder 8c is suitable for press working and the like, and can be mass-produced. The connecting rod 4' can be easily fitted by first pushing the largest diameter head of the connecting rod into the large diameter hole of the elastic body, and then fitting the valve holder 8c to the lower end of the cylindrical body 8a. It is possible. That is, the structure is easy to manufacture and assemble and is suitable for mass production. Further, since the valve 8 does not have a through hole, there is no risk of gas leakage. Moreover, high precision is not required in manufacturing. Overall, an inexpensive and safe gas solenoid valve can be provided.

Since the structure is configured to stop, the structure is simple, suitable for mass production, and easy to assemble. Furthermore, since there are no through holes, there is no risk of gas leakage. Furthermore, since two valve parts are constructed by connecting two valves to one plunger, even if one valve part malfunctions, the other valve part will close, ensuring safety. Ru.
