Seat the ball 102 with 02a on the seat ring 103.1
This is the main body of the ball valve that was clamped and pressed in step 03. 11 is a biasing means that is a compression coil spring, with a small gap opened at one end of the case 116 having the internal flow path 116a]
The plate 117 that opens and closes via the case 11
This is an excessive outflow prevention mechanism that is fixed to a rod-shaped valve body 105 with a seat fitted into the valve body 6. Then, the excessive outflow prevention mechanism 1 with the plays 1 to 117 facing outward is placed in the introduction path 101a mouth of the main body 101.
19 is screwed on. A tapered coil spring 118 is biased between the case 116 and the seat ring 103 to press the ball 102. Note that the plate 117 has fK 3 when the plate 117 is in a small gap open state.
A pressure equalizing hole 117a for '6 is provided. Therefore, the inlet path 10ta (il is connected to the container and the outlet ii'810
Fill the fluid from the outlet path 1.01 b (jIll) and use it. The valve at one end is closed.Even after the valve is closed, a small amount of fluid continues to flow out from the pressure equalizing hole 117a to the outlet path 101b.
The pressure on both sides of the valve body 17 is equalized, and the valve body 105 is connected to the biasing means 106.
The valve is removed and reset.

押下げてリセットする。FIG. 4 shows another example of high-pressure LP gas containers used domestically. A hexagonal nut 111 of a gas discharge device 114 containing a valve body 105, which is a ball, is placed in a storage chamber 101C between an inlet path 101a and an outlet path 101b.
In the case of excessive outflow due to breakage of the extraction circuit, etc., the outlet passage 10lb is depressurized, the valve body 105 floats up, and is blown away by the LP gas, causing the outlet passage to The valve 101b is closed by turning the operating part 110, which is the handle of the LP gas container valve 113, and the return rod 15 is pushed down from above the valve body 105 to reset it.

のものであった。``Problems to be Solved by the Invention'' However, such conventional ball valves with side overflow prevention devices have the following drawbacks. In the conventional example shown in FIG.
If it is provided in the main body 101, the total length of the main body 101 will be significantly increased, and the cost will also increase, which is meaningless in practical terms, so it has not been incorporated. In another conventional example shown in FIG.
17 or the filling speed slows down due to obstruction, and when overflow occurs, Tm
Even if it operates, a small flow rate continues to flow out from the pressure equalizing hole 117a, so it is not perfect. In yet another conventional example shown in FIG. 4, when the gas release preventer 114 operates to stop the valve 1'11, the handle of the container valve 113 is rotated to block the flow path while pushing the rod 115. I had to lower it and reset it. In this way, all of them had complex structures and incomplete functions.

る。"Function" When the valve of the ball 2 is opened, the driftwood flows from the introduction path 1a through the through hole 2a of the ball 2 to the outlet path 1b9, and the rotation of the operating part 10 causes the ball 2 to engage with the stem 8. Close the valve. In the overflow prevention mechanism, when the valve is open, the valve body 5 does not close the valve seat 2c during normal flow. When a larger flow of fluid than a predetermined amount is released due to damage to the ll'2 output circuit, etc., the pressure in the outlet path lb is reduced, and the valve body 5 pressed by the fluid closes the valve seat 2c. Then, when the ti W part 10 is rotated to close the valve of the ball 2, both openings of the through hole 2a of the ball 2 become equal pressure inside the storage chamber 1c, and the valve body 5 is moved by the biasing means 6 containing its own weight. As a result, the valve moves away from the valve seat 2c and is reset to the slightly opened state.

seat rings 3, 3 in the storage chamber 1c of the main body 1 having
A cylindrical body cap 4 is pressed and screwed from behind on the introduction path la side, and a leak-preventing sheet gasket 9 is interposed on the stem 8 that engages with the ball 2. The operating section 10 is installed. In this ball valve, a valve chamber 2b whose diameter is enlarged on the introduction path la side of the through hole 2a of the ball 2 is placed so as to face a valve seat 2c in a step at the back of the valve chamber 2b, and a seat surface is placed on the valve head. A valve body 5 having a plurality of flow passages 5a on its outer periphery is inserted into a slightly open valve state by interposing a biasing means 6, which is a compression coil spring, which operates to close the valve against a biasing force at a predetermined flow rate. The valve body 5 is supported by a C-shaped support piece 7 in an annular groove at the mouth of the valve chamber 2b to prevent its removal. In addition, the threaded part may be double-prevented from leaking by applying a sealant, attaching a sheet seal, etc. Then, the operation part 1 is attached to the main body 1 of the stem 8 part, and the pipes are connected to the female screws of the inlet 18 port and the outlet port lb port.
By providing a locking mechanism that opens and closes 0, it can also be used as a flexible tube cock or intermediate cock for a low-pressure gas cock.

器に直接組込むことも出来る。FIG. 3 shows yet another embodiment of the invention, which is a gas release preventer connected to a valve for a high pressure I-P gas container. In this embodiment, a hexagonal nut 1 for connection is attached to the inlet 18.
A seat ring 3 is pressed by a nipple-shaped body cap 4 having a body cap 1 fitted on the outside, and is screwed onto the main body 1. A leak-preventing seal 12 such as an O-ring or a square ring is fitted onto the conical surface of the tip of the body cap 4. and,
The body cap 4 is brought into contact with the filling port of the high pressure LP gas container valve, and the hexagonal nut 11''C is screwed on 9 and the outlet path l.
A supply pipe is interposed on the b side, or a regulator is directly connected to take out the reduced pressure LP gas. In addition, instead of 1 hexagonal nut, 1 hand-tight handle can be used. Therefore, instead of being reset by pressing down as in the conventional example shown in FIG. 4, the reset is performed simultaneously when the valve 2 of the ball 2 is turned off by the rotation of the operating portion 10. In this way, we have added a stop valve function to gas release preventers, which previously did not have a stop valve function, without changing the product price, further improving safety and ensuring reset. Furthermore, this gas release preventer of the present invention can also be directly incorporated into a valve for a high-pressure LP gas container or a regulator.

It is possible to prevent the valve body 5 from being removed by inserting a supporting piece 7 such as an S-shaped ring having spring properties into the annular groove of the opening of the valve chamber 2+-+ to prevent the valve body 5 from being removed.9 In that case, A separate biasing means 6 such as a compression coil spring is not required, and the weight of the spherical valve body 5 plays its role. In this way, the biasing means 6 includes its own weight.
