The spring 220 applies an urging force to a packing 240 described later, and the washer 230 prevents deformation of the packing 240 due to the urging force of the spring 220. The packing 240 is formed of elastic rubber, and the barrel stopper 1 is formed by expansion and contraction of the spring 220.
00 constitutes the valve.

[0007] The other body 400 constituting the barrel plug 100 is hollow and cylindrical, and a tube 210, a spring 220, and a washer 2 are provided in the hollow portion.
30 and a packing 240 are accommodated. One end of the body 400 has a tube 210
Cutouts 410A, 410B, 410C for inserting and engaging with the projections 213A, 213B, 213C. The notches 410A, 410B, and 410C are formed in an inverted L-shape, and a recess 420 is formed at the tip of the L-shape.
A, 420B and 420C are provided. Body 4
In the middle part of 00, a plurality of openings 450 are formed,
The beer stock solution can be moved inside and outside the body 400. A male screw 440 to be screwed into a female screw (not shown) provided on the barrel main body 101 is formed on the outer periphery of the other end of the body 400, and the barrel stopper 100 is formed on the other end.
A flange 430 for attaching or detaching the barrel to or from the barrel main body 101 is provided.

The operation of assembling the barrel stopper 100 configured as described above will be described. First, the spring 220 is inserted through the tube 210. After the insertion, the washer 230 is fitted to the packing 240 and is engaged with the other end of the spring 220 inserted into the tube 210. And packing 24
0 is pushed into the flange 213 side of the tube 210. At this time, one end of the spring 220 is connected to the flange 21 of the tube 210.
3, the spring 220 is compressed by the force for pushing the packing 240.

As it is, the packing 240 is
When the packing 240 is pushed into and released from the inside of the stainless steel plate 211, that is, the opening 212, the packing 240 tends to return to the original position by the repulsive force of the spring 220. However, the stainless steel plate 211 provided at the other end of the tube 210 has a diameter different from that of the tube 210 and protrudes to form a protruding portion 211A. Therefore, when the packing 240 attempts to return to the original position by the repulsive force of the spring 220, the groove 241 formed on the inner periphery of the packing 240 is formed by the protrusion 211A of the stainless plate 211.
Lock at. Thus, the valve 200 is formed.

When the valve 200 is formed, the distance from the tip formed by the stainless steel plate 211 of the tube 210 and the packing 240 to the flange 213 of the tube 210 is determined by the notch 41 from the flange 430 of the body 400 described later.
0A, 410B, 410C depressions 420A, 420B,
It is formed with a length equal to the axial distance up to 420C.

Next, the valve 20 formed as described above is used.
0 is stored in the body 400. When storing,
First, the valve 200 is inserted into the hollow portion of the body 400. The tip of the valve 200 inserted into the hollow portion, that is, the stainless plate 211 of the tube 210 and the packing 2
The tip formed by 40 is engaged with the flange 430 of the body 400, and the protruding portions 213A, 213B, 213C of the tube 210 of the valve 200 are inserted into the notches 410A, 410B, 410C of the body 400. Then, the tube 210 is rotated in the horizontal direction in the direction of the L-shaped tip, so that the protrusions 213A, 213B, 213C of the tube 210 are engaged with the depressions 420A, 420B, 420C.

However, as described above, the tube 210
The distance from the tip formed by the stainless steel plate 211 and the packing 240 to the flange 213 of the tube 210 is determined by the notch 410A, 410B, 41 from the flange 430 of the body 400.
The tube 2 is formed with a length equal to the axial distance to the depressions 420A, 420B, 420C of 0C.
Even if 10 is rotated, the protrusion 213A of the tube 210,
213B and 213C are depressions 420A, 420B and 420
It does not turn in the direction of C.

Therefore, the packing 240 is pushed in the direction of the flange 213 of the tube 210 from the side of the flange 430 of the body 400, and the spring 220 is slightly contracted to shorten the distance between the packing 240 and the flange 213 of the tube 210. Therefore, the body 400 can be moved up and down in the axial direction by the reduced distance. Thus, when the body 400 is lifted and rotated,
Projecting portions 213A, 213B, 213C of tube 210
Are engaged with the depressions 420A, 420B, 420C. On the other hand, since the compressed spring 220 has a repulsive force, when the compression is released, the groove 241 of the packing 240 is locked at the projection 211A of the stainless steel plate 211 of the tube 210 and the projection 213 of the tube 210 is released.
A, 213B and 213C are pressed against the depressions 420A, 420B and 420C by the repulsive force of the spring, and
0 does not easily come off the body 400.

Thus, the barrel stopper 100 is assembled. When disassembling the barrel stopper 100, the reverse operation may be performed. That is, first, the packing 240 of the valve 200 is pushed in from the side of the flange 430 of the body 400, and the body 400 is rotated, so that the valve 200 and the body 40 are rotated.
Decompose 0. When disassembling the valve 200, the packing 240 of the valve 200 is detached from the stainless steel plate 211 and disassembled into the tube 210, the spring 220, the washer 230, and the packing 240.

The handling of the barrel stopper 100 will be described. First, when a beer barrel is shipped from a beer factory, the barrel body 101 is filled with a beer stock solution and the barrel stopper 100
And delivered to restaurants, etc. via distribution channels. When the undiluted beer solution is consumed at the delivered restaurant or the like, the empty beer barrels are collected at a beer factory for reuse. In the beer factory, the collected barrel body 10
The first barrel stopper 100 is opened to clean the inside of the beer barrel. With regard to the barrel plug 100, the valve 200 and the body 400 are disassembled and washed, respectively, and, for example, the packing 240 is inspected for abnormalities such as whether its useful life has passed, whether it has risen or cracked, and the like. If there is any abnormality, replace the valve with a new valve and assemble the new valve and the body 400. If there is no abnormality, assemble the valve 200 and the body 400 again,
Used as a barrel stopper 100. Here, as for the valve 200 having an abnormality, there is a problem in quality control. Therefore, as described above, the packing 240 must be removed from the valve 200, disassembled into each component, and parts must be replaced.

[0016]

However, there have been the following problems in the disassembly of the valve. That is, when disassembling the valve 200, the packing 240 is pulled off from the stainless steel plate 211 of the tube 210, but a strong force is required to pull off the packing 240. In the past, since this was performed manually, there was a limit to the number of valves that could be disassembled by a given number of people within a given time. In addition, there is a problem in that a strong force is required, so that a skilled person must rely on it, that is, no one can easily disassemble it. Further, the packing 240 is
When removing from the stainless steel plate 211 of the
Due to the urging force of the spring 220, the spring 10 projects in the axial direction with momentum, and in some cases, there is a risk of damaging humans and objects, that is, there is a problem of lack of safety.

Accordingly, an object of the present invention is to provide a valve disassembling apparatus which can improve the working efficiency in disassembling a valve while maintaining safety and can disassemble the valve by a simple method.

[0018]

The washer 230 is pushed up to compress the spring 220. At this time, the packing 240 is attached to the holding plates 17A, 1A.
8A and the holding blades 17C and 18C, the valve 200 only compresses the spring 220. However, the protrusion 15B of the tip fitting 15A has a height equal to the height of the four metal rods 15D, 15E, 15F and 15G. It hits the stainless steel plate 211 with a time difference delayed by the difference in height. For this reason,
As shown in FIG.
Is released from the packing 240, the tube 210 jumps out in the axial direction due to the repulsive force of the spring 220, and the flange 213 of the tube 210 collides with one end of the receiving block 22. As described above, the tube 21 that projects upward in the axial direction
Since 0 is caused to collide with the receiving block 22, no damage is caused to humans or objects.

Therefore, as shown in FIG. 10, while the operation button 13A of the main valve 13 is being depressed, the operation lever 14A of the manual valve 14 is operated to
The compressed air is sent to the vertical cylinder 15 via OF. Then, the shaft 15B moves downward and the tip fitting 15A
Returns to its original position. Next, the hand is released from the operation lever 14A of the manual valve 14, and the operation switch 16A of the mechanical valve 16 is operated to return to the original state. Thereby, the compressed air remaining in the mechanical valve 16 is discharged outside the valve. When the operator releases the operation button 13A of the main valve 13, the holding plates 17A and 18A are released.
Returns to the original position by the restoring force of the springs 17D and 18D. Thus, the disassembling operation of the valve 200 is completed.
