In detail, by attaching the intake cap and moving the valve stem back and forth, air is sealed when the valve is opened, and gas is sealed when the valve is closed.When the valve is closed, the surface of the valve body is flush with the valve body and the inner surface of the pressure vessel. This relates to a gas filling valve that protects the bladder by completely closing the valve and, in the event of an abnormal temperature rise, melts the temperature fuse and releases air to the outside to ensure safety.

てしまう。(Problem to be solved by the invention) The gas filling valve described in the above-mentioned Japanese Patent Publication No. 55-21237 does not have its inner end protruding into the pressure vessel, but has an air supply port in the center of the inner end. It is clear from the drawing that the gas filling valve is open, and the gas filling valve described in JP-A-55-20924 is only shown so that its inner end does not protrude into the pressure vessel; It is not shown that the air inlet opens at the center of the figure. However, without the air inlet, gas cannot be introduced into the bladder, so it is obvious that this valve also has an air inlet opening at the center of the inner end. Therefore, in any of the above-mentioned gas filling valves, when the bladder is brought into pressure contact with the air inlet opening at the inner end, the gas pressure causes a punching action to create a hole in the bladder.

Since it is also used as a valve, a valve seat is formed in the valve casing, a circular valve stem and a coil spring are provided, a flexible valve material is filled in the valve stem, and the upper end of the flexible valve material is Since it is necessary to adopt a complicated structure that makes contact with the valve seat, it is not only expensive to manufacture, but also
Since the air inlet is opened at the center of the inner end of the valve, when the internal pressure of the bladder decreases, the lower part of the bladder is pressed against this air inlet by hydraulic pressure, causing a punching effect and creating a hole. .

ばならない場合には使用できない。 Furthermore, the forcibly opened/closed valve described in Japanese Utility Model Publication No. 58-170467 has a valve handle formed integrally with the valve body screwed onto the casing, a handle attached to this valve handle, and a handle that can be opened and closed while being rotated. The valve body is opened and closed by moving it, so connect the intake cap to the valve handle,
It cannot be used when the valve body must be opened and closed by moving the valve handle without rotating.

When the valve body is seated on the valve seat, the air supply hole is completely blocked without any protrusions inside the pressure vessel, achieving the purpose of bladder protection. The object of the present invention is to provide a gas-filled valve that opens an air supply hole by melting a temperature fuse, releases gas from inside a pressure vessel, and prevents the pressure vessel from bursting due to pressure increase.

してこれに充填される。(Function) When the gas filling valve for a pressure vessel constructed as described above is closed as shown in FIG. When the cap 27 is attached and the adjusting nut 18 is turned in one direction, the valve handle 14 does not rotate and the pressure vessel 1
0 and moves the valve body 19 away from the stepped valve seat 13 to open the valve. Therefore, when air is supplied from the pressurized air source in this state, the gas flows through the air supply hole 2.
0, flows into the annular groove 21 through the horizontal hole 22, and flows into the valve seat 13.
The liquid flows into the pressure vessel 10 through the space between the valve body 19 and the valve body 19, and is filled into the pressure vessel 10.

Since the hole 11 of the valve body 8 is completely closed and its surface is flush with the inner end of the cylindrical valve body 8 and the inner surface of the pressure vessel 1, air is not supplied from the valve body 8 in this state. If the cap 27 is removed and the protective cap 26 is attached, the bladder 9 will not be damaged even if the bladder 9 is forcefully pressed against the valve body 19 due to an increase in hydraulic pressure. In addition, when the pressure vessel 1 is heated to an abnormally high temperature due to fire or other causes and the gas filling valve is in a dangerous state that could cause an explosion due to the expansion of the internal gas, the valve body 1 should be closed.
The temperature fuse 25 fitted in the large diameter portion 20' of the air supply hole 20 opening at the center of the pressure vessel 1 melts and communicates the inside of the pressure vessel 1 with the atmosphere through the air supply hole 20 and the air discharge hole 28. The gas inside the pressure vessel 1 is released to the outside to protect the pressure vessel 1.
