くパツキン４の前置が短いという欠点がある。Conventional technology and problems Conventionally, there are two types of pressure vessel valve fittings: one connects using compressed air pressure, and the other connects manually by screwing into the container valve. When the supply pressure of compressed air decreases, it may stop functioning and cause gas leakage, etc. For the manual type, a gasket 4 is attached to one end and a connection part 10 is attached to the other end, as shown in Figure 5. The nozzle 3 is attached to the packing contact surface 21 of the filling port 20 by screwing the push metal fitting 26 having a threaded portion 25 at the tip into the threaded portion 27 of the filling port 20 of the pressure vessel valve 19.
Press the gasket 4 to connect the gasket contact surface 21 and nozzle 3.
Since this work is performed more than 100 times a day, it takes a lot of effort to install and remove the pusher fitting 26, and the seal 4 is often pressed more than necessary. It has the disadvantage of being short.

Reference numeral 1 denotes a main body, and the main body 1 is provided with a cylindrical hole portion 2, and a slidable nozzle 3 is attached to the cylindrical hole portion 2. A packing 4 is attached to the front end of the nozzle 3, and the outer diameter of the rear part of the nozzle 3 is made into a small diameter tube 5. 3 is energized in front. A retaining ring 8 is attached to a groove 9 at the rear of the nozzle 3 to prevent the nozzle 3 from flying out forward. A screw 10 is formed at the rear end of the nozzle 3 for connection to a fluid or vacuum source (not shown). Grooves 1 are formed on both left and right sides of the main body 1.
1.11° is provided, and a hook 12. is provided in the groove 11.11°.
12- is rotatably housed in the bin 13.13'. The front tip of the hook 12.12゛ is bent inward,
In addition, a spring 14.14゛ is installed inside the hook 12.12゛ in front of the bottle 13.13° so that the front of the hook 12.12- opens outward. The main body 1 is provided with a slidable sleeve 16.
A dipping 17 is formed at the rear end of the main body 1, and a ring 18 for preventing the sleeve 16 from being pulled out is fitted in the groove 17, and the front end of the main body 1 has a diameter larger than the inner diameter of the sleeve 16.
6 as a stopper in the forward direction.
次に上記構成を有する圧力容器弁継手の作用を説明する
。Next, the operation of the pressure vessel valve joint having the above configuration will be explained.

とする力が発生する。The main body 1 is inserted into the filling port 20 of the pressure vessel valve 19, and the packing 4 is brought into contact with the packing contact surface 21.
When pushed forward, the sleeve 16 pushes the side surface 22.22' of the hook 12.12-, generating a force that tends to release the hook 12.12-.

As long as the force of the spring 14, which automatically biases the hook 12.12- to open the hook 2-, is stronger, the hook 12.12' will not be closed, and the nozzle 3 will be moved through the spring 7 when the hook 12.12- is closed. Since the nozzle 3 is pushed forward, the seal 4 of the nozzle 3 is pressed against the seal contact surface 21 to form a seal. Pushing the sleeve 16 further forward compresses the spring 7 and the hook 12.12- snaps to clamp the outer surface of the pressure vessel valve 19. After the hook 12.12- is fully engaged, the sleeve 16 is further advanced and the side 22 of the hook 12.12-
．． 22 is pressed by the inner surface 23 of the sleeve, the clamped state of the hook 12.12- is maintained, and the nozzle 3
does not escape from the filling port 20 of the pressure vessel valve 199
When removing this pressure vessel valve joint, the sleeve 16 is pulled rearward to open the hook 12, 12-, and then the nozzle 3 is removed from the filling port 20.

。In the above embodiment, the outer surface 22.22' of the flap 12.12- is pressed by the inner surface 23 of the sleeve 16 to close the hook 12.12-. It is also possible to press the inner surface of the hook 12.12' at the rear of the bottle 13.13- with the outer surface of the sleeve 16 to engage the hook 12.12-.

If the packing 4 is further pushed against the packing contact surface 21 by the product of the difference in pressure receiving area due to the difference in their outer diameters and the pressure of the fluid, the high pressure fluid can be sealed. In this case, the connection with the fluid is made at the connection part 10 provided on the main body.
24-1 is the piston seal.

ができる。As described in detail, according to the present invention, when connecting a joint to a pressure vessel valve, the connection can be made quickly and reliably by simply touching the seal against the seal contacting surface of the filling port of the container valve and pressing the sleeve. In addition, since the sleeve can be removed by simply pulling it backwards, it is possible to save labor in attaching and detaching the pressure vessel valve and the joint.
また圧縮空気を利用しないので、圧縮空気の圧力降下に
