Abstract

PURPOSE:To prevent an actuator from projecting from a top plate, by locating the actuator at a fixed position spaced apart from a main valve, and connecting an output shaft of the actuator with an opening/closing operational portion of the main valve by a universal coupling. CONSTITUTION:An actuator 5 is not directly mounted on an upper portion of a bomb 1, but it is located outside a bomb accommodation box 2 in spaced relationship from the bomb 1. That is, the actuator 5 is not interposed between the upper portion of the bomb 1 and the bomb accommodation box 2, thereby preventing a space above the bomb 1 from being blocked. Accordingly, upon replacing another bomb having a large capacity, the actuator located above a tank as in the prior art may be prevented from contacting a top plate 2. Further, since a driving torque of an output shaft 6 of the actuator 5 is transmitted through a universal coupling 7 to a chuck 8, it is not necessary to make a position of the output shaft 6 coincident with a position of an operation handle 3a of the main valve 3.

The conventional cylinder main valve emergency shutoff device that opens the cylinder main valve in this way has an actuator installed integrally with the cylinder above the main valve, and an operation signal is supplied to this actuator to open and close the main valve. It was designed to be operated. Further, the output shaft of the actuator was provided with a connecting member having a claw portion that was connected to the outer circumferential recess of the operating handle of the main valve.

'In the shutoff device, the actuator was installed directly above the cylinder, so when replacing a cylinder and storing a large-capacity cylinder in the cylinder storage box, the space between the actuator and the top plate of the cylinder storage box becomes narrow. In some cases, the actuator protrudes from the top plate, necessitating modification of the cylinder storage box. Furthermore, when attaching the actuator to the cylinder, it is necessary to align the output shaft of the actuator with the center position of the operating handle of the main valve, which limits the attachment position of the actuator.

したがって、アクチュエータの出力軸の位置をチェック
に一致させるように調整しながらボンベに取付けるため
、ボンベ設置作業に手間がかかり面倒であるという欠点
があった。Therefore, since the position of the output shaft of the actuator must be adjusted to coincide with the check before being attached to the cylinder, there is a drawback that the cylinder installation work is time-consuming and troublesome.

そこで、本発明は上記欠点を除去したボンベ元弁緊急連
断装置を提供することを目的とする。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cylinder main valve emergency connection device that eliminates the above-mentioned drawbacks.

Furthermore, by connecting the output shaft of the actuator and the opening/closing part of the main valve with a universal joint, the actuator can be placed out of the way, eliminating the need to modify the cylinder storage box and making it easier to install large-capacity cylinders. It is designed so that it can be installed on.

の外部に供給される。The main valve 3 has an operating handle 3a on its upper part for opening and closing operations. Therefore, the opening degree of the main valve 3 is adjusted by rotating the operating handle 3a. Therefore, gas flows out from the cylinder 1 at a flow rate corresponding to the valve opening degree of the main valve 3.

弁し、その弁開度を調整される。Here, when adjusting the flow rate of gas in the cylinder 1 or when opening/closing the cylinder 1, first, an operation switch or the like of the operation device 9 is operated to supply an operation signal to the actuator 5. As a result, the solenoid valve s connected to the air pipe 10
=, 51:i is activated, and air pressure from the air pipe 10 is introduced into the cylinder portion 5C of the actuator 5, displacing the piston (not shown). In this way, the actuator 5 operates and the output shaft 6 is driven. The rotational driving force of the output shaft 6 is transmitted to the chuck 8 via the universal joint 7. That is, the operating handle 3a of the main valve 3 is driven by the output shaft 6 of the actuator 5 and rotates to open and close the main valve 3. Therefore, the main valve 3 of the cylinder 1 is opened and closed by remote control of the operating device 9, and its opening degree is adjusted.

ボンベ収納ボックス２を改造する必要もない。Therefore, the actuator 5 is not interposed between the upper part of the cylinder 1 and the cylinder storage box 2, and the upper space of the cylinder 1 is not blocked. Therefore, for example, when replacing a cylinder with a larger capacity cylinder, there is no inconvenience such as the actuator at the top of the tank coming into contact with the top plate 2 as in the conventional case.
There is no need to modify the cylinder storage box 2.

しうるガス漏洩事故等を未然に防止しつる。Furthermore, since the driving force of the actuator 5 is configured to open and close the main valve via the universal joint 7, there is no need to match the position of the output shaft 6 of the actuator 5 with the position of the operating handle 3a of the main valve 3. The respective mounting positions do not have to be accurate. In addition, when replacing the cylinder 1, the chuck 8 is inserted from the operating handle 3a while the actuator 5 is attached to the top plate 2.
You can easily replace the cylinder by simply removing the . In addition, Bell 1-1, which was holding cylinder 1 due to an earthquake, etc.
3 may come off or be cut off. Even in such a case, the cylinder 1 is held via the output shaft 6, the universal joint 7, and the chuck 8 so as not to fall. That is, the cylinder 1 is prevented from falling over even if the cylinder 1 shakes or tilts at a slight angle due to the bending of the universal joint 7 when the belt 13 comes off. This is advantageous in terms of safety in the event of an earthquake, and prevents gas leakage accidents that may occur due to the cylinder 1 falling over.

きる。Further, the height of the cylinder 1 varies depending on its capacity. - In this case, as shown in FIG. 3, the distance between the position of the operating handle 3a of the main valve 3 and the top plate 2a of the cylinder storage box 2 is different. Therefore, cylinder 1a with large capacity
In this case, the distance between the operating handle 3a and the top plate 2a is f

Since the actuator 5 is provided outside the cylinder storage box 2, the pedestal 11 can be easily provided between the top plate 2a and the actuator 5. Therefore, pedestal 1
1, the height position of the actuator 5 can be adjusted without changing the bending angle of the universal joint 7.

In FIG. 2, the actuator 5 is placed on the bottom surface 2b of the cylinder storage box 2, which is a fixed part. Furthermore, the output shaft 6 of the actuator 5 and the shaft 8a of the chuck 8 are connected by a flexible tube 12. Therefore, the rotational driving force of the output @6 of the actuator 5 driven by the supply of the opening/closing signal from the operating device 9 is transmitted to the chuck 8 via the flexible tube 12, and the main valve 3 is opened and closed.

Further, since only the bent flexible tube 12 is interposed between the main valve 3 and the top plate 2a, there is no problem even if the space between the main valve 3 and the top plate 2a is narrow. Therefore, a cylinder 1 having a larger capacity than conventional cylinders can be stored in the cylinder storage box 2.

This eliminates the inconvenience of protruding cylinders, and therefore eliminates the waste of remodeling the cylinder storage box. moreover,
There is no need to remove the actuator when replacing cylinders.
In addition, when installing the cylinder, there is no need to align the position of the cylinder main valve exactly with the position of the output shaft of the actuator and the output shaft, and it can be installed offset, making it easy to replace the cylinder. .
