[Detailed description of the invention] The present invention relates to a starter container valve opener that is attached to a container, especially a fire extinguishing gas container, and its purpose is to prevent the valve from opening accidentally even if there is a change due to vibration or the like. To provide a starting container valve opener that is safe, durable for long-term use, easy to operate, and has exceptionally high performance that can fully open quickly and reliably to release gas. Furthermore, it has a simple structure and can provide reliable operation. There is something to do.

In general, container valves used in this type of fire extinguishing equipment are required to be able to fully open quickly and reliably, with no gas leakage even under vibration or temperature changes, and with easy operation.

However, although some container valve openers to date have excellent operability, there is a considerable risk of them opening accidentally due to vibrations, etc., and therefore they have the fatal drawback of not being able to withstand long-term use. there were.

The present invention focuses on the above-mentioned points and relates to a completely new starting container valve opener that does not open accidentally, has excellent operability, and can withstand long-term use. An opener for a starting container valve that is attached to the mouth and opens the mouth by breaking a sealing plate provided on the mouth with a cutter, which has a notch in a recess formed in the inner wall of a housing formed in the opener main body. A support shaft is attached to the other end of the lever, one end of which is attached to a pin that cooperates with the elevating rod, and a cutter for opening the seal plate is provided at the lower end in the housing, and an elevating tube with a spring inside is installed. Furthermore, the elevating tube is formed with a notch that can be locked to the support shaft, and when the elevating tube and the support shaft are unlocked, the elevating tube is lowered and the cutter breaks the sealing plate. .

The specific configuration thereof will be explained below according to an embodiment shown in the drawings.

Reference numeral 1 denotes a container body having a sealing plate 2 for preventing leakage at the mouth after being filled with fire extinguishing gas, and 3 a release device for an activation container valve 4 screwed onto the mouth of the container body 1. Main body, 5
is a solenoid, and 6 is an elevating rod that also serves as a solenoid plunger, and is normally raised by a spring 8 that is stopped by a spring stopper 7.

Reference numeral 9 denotes a notched groove formed on the upper side surface of the lifting rod 6; 10 denotes a push button having a pusher pin 11 stopped on the lifting rod 6; and 12 penetrates the notched groove 9 formed in the lifting rod 6. It is raised and lowered in accordance with the raising and lowering of the lifting rod 6 using the pins.

13 is a lever whose one end is rotatably attached to the pin 12; 14 is a support serving as a stopper having a notch 15 formed approximately in the center along the outer circumferential surface of the elevator cylinder in the short axis direction; The shaft is fixed to the other end of the lever 13 by welding.

16 is a housing formed by a protruding wall 17 formed on a part of the opener body 3 and a facing wall 18;
A recess 19 for inserting the support shaft 14 is formed in the upper inner wall of the support shaft 14 .

Reference numeral 20 denotes an elevating cylinder which is internally equipped with a cutter spring 23 whose one end is fixed to the plug plate 21 on the top of the housing 16 and the other end is fixed to the locking part 22. A notch 24 is formed.

25 is a cutter screwed onto the locking portion 15 of the elevating tube 20, 26 is a container valve gasket, and 27 is a gas discharge pipe.

Since the present invention has the above-mentioned configuration, before the gas in the container main body is released, that is, before the starter valve opener operates, the elastic force of the spring 8 is applied as shown in FIGS. 1 and 2. Since the elevating rod 6 is in the raised position, the support shaft 14 fixed to the lever 13 is located on the lower side where its notch 15 is separated from the notched upper wall 20' of the elevating tube 20, as shown in FIG. Therefore, the support shaft 14 and the cutout top wall 20' are in a locked state.

As a result, the elevating tube 20 is positioned above the housing 16 against the elastic force of the cutter spring 23, so that the cutter 25 provided at the lower end of the elevating tube 20 moves toward the container body 1.
It is positioned above the sealing plate 2 provided at the mouth of the machine, and the sealing plate 2 is never broken.

In particular, the cutout top wall 20' formed in the elevator tube 20 is connected to the support shaft 1.
Since it is locked at the central fulcrum of 4 and prevented from descending, the locked state is ensured, so even if vibration etc. occur, the lock will not be accidentally released and the elevator cylinder 20 will not fall. Extremely safe.

Next, when a fire breaks out and it becomes necessary to release the force inside the container body 1, that is, when opening the container by breaking the sealing plate 2, first manually press the push button 10. Pusher pin 11 lowers lifting rod 6 against the elastic force of spring 8.

When the lifting rod 6 descends, the pin 12 inserted through the notched groove 9 of the lifting rod 6 also lowers at the same time, and the lever 13 rotates counterclockwise about the support shaft 14.

As the lever 13 rotates, a support shaft 14 fixed to the other end of the lever 13 rotates in the same direction.

This rotation of the support shaft 14 causes the notch 15 formed in the support shaft 14 to open onto the notch top wall 20 of the elevator tube 20 as shown in FIG.
Therefore, the notch top wall 20' and the support shaft 14 are disengaged, and the cutter spring 23 in the elevating tube 20 is disengaged.
The elevating cylinder 20 is lowered by the elastic force.

The cutter 25 provided at the lower end by lowering the elevator tube 20
The tip of the container descends and breaks through the sealing plate 2 of the container body 10.

If the sealing plate 2 is broken, the extinguishing gas inside the container body 1 will be discharged from the discharge pipe 2.
7 to the outside.

In this way, the starting container valve opener according to the present invention is equipped with the lifting rod 6.
By lowering the lever 13 and rotating the support shaft 14, the elevator cylinder 2 that was locked by the support shaft 14 is removed.
0 can be lowered extremely accurately, so that the sealing plate 2 can be reliably broken with the cutter 25.

In the above embodiment, the lifting rod 6 is lowered manually by lowering the pusher pin 11 by pressing the push button 10. It is also possible to rotate the lever 13 by an electrical method that suctions the rod 6 downward against the elastic force of the spring 8, and in this case there is an advantage that it becomes a high-performance automatic opener.

Therefore, the means for lowering the lifting rod 6 may be automatic or manual.

Further, in this embodiment, the pivot shaft 14 is attached to the other end of a lever 13, one end of which is attached to a pin 12 that moves together with the lifting rod 6, to control the rotation of the pivot shaft.
is fixed, and the support shaft 14 is rotatable by raising and lowering the elevator rod 6, and the elevator cylinder 20 locked to the support shaft 14 is configured to be able to fall.The means for rotating the support shaft 14 is The present invention is by no means limited to this embodiment, and for example, the support shaft may be rotatable via a gear interlocked with the lifting rod, and the rotating means is not limited in any way.

The design of other means can be changed within the scope of the present invention.

In this invention, as shown in the above example, by lowering the elevator rod and rotating the support shaft via a lever, the elevator cylinder, which is locked to the support shaft and prevented from descending, is caused to fall. Therefore, the sealing plate is reliably broken using a cutter provided on the elevator tube, and gas can be released.

In particular, there is an advantage that the sealing plate can be opened quickly and easily due to the reliable operation.

On the other hand, when the starting container valve release device is not in use, the support shaft and the elevating tube are locked, so even if vibration occurs during handling, the elevating tube will be reliably prevented from falling by the support shaft and will not malfunction. Safety is ensured as the cutter will not break the seal if the lift tube falls easily.

Therefore, it is effective for long-term use.

Furthermore, since the elevator tube is lowered by rotating the support shaft as a stopper, it can be moved extremely smoothly and is easy to operate.

In addition, it has great practical effects as a container valve opener that can be operated manually or automatically.
