同様の作用を営ませ得る。 The object of the present invention is to obtain a device free from such disadvantages, in which a gas stop or other closure 1 is connected to the power source 2 via a clutch 6 which closes upon excitation of an actuating solenoid 5 connected to the power source 2. In the case of a type in which the closing member 1 is connected to a motor or other drive source 3 connected to the clutch 6, and the closing member 1 is actuated to the opening side by the driving source 3 against the return spring 4, the closing member 1 is connected to the clutch 6. A ratchet is provided on the shaft 15 separate from the shaft 16 provided with the clutch 6 which is interlocked via the reduction gear train 13 on the output side, and on the input side of the clutch 6 of the shaft 16, which allows normal rotation but prevents reverse rotation. Another mechanical check mechanism 7 is provided, and the spring 4 is provided on the output side of the clutch 6, and the drive circuit of the drive source 3 responds to the cam 20 on the separate shaft 15 to open the closing member 1 at the fully open position. A control switch 19 is provided,
In the illustrated example, in addition to the shaft 16 provided with the clutch 6, a shaft 10 is provided which is connected to the drive source 3 via gears 8 and 9, and the shaft 10 and the shaft 16 are connected to the gears on the input side of the clutch 6. 11 and 12, and the reduction gear train 13 consists of a small diameter gear 13a on a shaft 16 and a large diameter gear 13b on a shaft 15, and the check mechanism 7 is, for example, as shown in FIG. It consists of a ratchet wheel 7a and a ratchet pawl 7b that engages with the ratchet wheel 7a, which is fixed to the side surface of the gear 12 on the input side of the ratchet wheel 7a, and the spring 4 is attached to the shaft on the output side. One end was fixed to the outer periphery of 15. The non-return mechanism 7 is not limited to the ratchet type described above, but may also be of a worm or worm gear type, for example. The clutch 6 consists of two halves 6a, 6a on the input side and the output side, one of which is connected to a spring 5a in the solenoid 5 via a laterally extending shaft 16 and a lever 17 connected to the shaft 16. It is connected to an actuating element 5b which is freely movable downward against the pressure, so that when the actuating element 5b is moved downward, the two halves 6a, 6a are mutually closed. The solenoid 5 is connected to the power source 2 via a power switch 18, as shown clearly in FIG.
The drive source 3 includes a control switch 19 and a switch 18.
The control switch 19 responds to the cam 20 on the shaft 15 to open the closing member 1 at a predetermined position, for example, a fully open position. In other words, it is always closed. Note that the spring 4 is not limited to being provided with one end fixed on a separate shaft 15 as shown in the figure, but it can also be provided with one end fixed on the shaft 16 on the output side of the clutch 6 to achieve the same effect. It can be done.

作動を停止される。 To explain its operation, when the power switch 18 is closed, the operating solenoid 5 is energized and the clutch 6 is energized.
As the switch closes, the drive source 3 is energized and activated via the control switch 19, and the closing member 1 is driven by the drive source 3 and gradually opens against the return spring 4. Next, when the fully open position is reached, the switch 19 is opened, and the drive source 3 is thus stopped from operating.

も同様であり、安全性が保たれる。 At this time, the spring 4 gradually increases its elasticity and acts on the closing side of the closure 1, that is, on the reverse side, but this reverse action is stopped by the check mechanism 7, and the closure 1 is held in that position. stay. Next, when the power switch 18 is opened, the operating solenoid 5 is de-energized and the clutch 6 is opened, so that the non-return mechanism 7 is separated from the output side of the clutch 6, and therefore the closing mechanism is closed on the output side. 1 becomes the closed side when the spring 4 is applied.
This also applies when a power outage or other accident occurs on the power supply 2 side, and safety is maintained.

る等の効果を有する。 As described above, according to the present invention, the check mechanism 7 is provided on the input side of the clutch 6, and the return spring 4 is provided on the output side of the clutch 6. When the clutch 6 is opened, the spring 4 acts on the closing member 1. When the clutch 6 is closed, the check mechanism 7 acts to hold the closing member 1 in its open position, and the brake solenoid, etc. No stopping means is required, especially mechanical check mechanism 7
When using a clutch 6, it is necessary to allow some play, but the closure 1 must be placed on the output side of the clutch 6 on a shaft 15 separate from the shaft 16 on which the clutches 6 are interlocked via a reduction gear train 13. and the shaft 16
When the check mechanism 7 is provided on the input shaft of the clutch 6, the reduction gear train 13 reduces the amount of movement due to the play of the check mechanism 7 and transmits it to the closure 1.
This has the advantage of being able to reliably stop the valve at a desired valve opening position.
