つける必要がある。2. Description of the Related Art To flange-connect pipes, a packing is interposed between the flange surfaces in order to ensure a seal at the joint. A packing for sealing, which is usually made of an elastic material such as rubber, is formed in a ring shape according to the shape of the flange surface, and a plurality of bolt holes are evenly provided in the circumferential direction. Then, insert the bolt from one flange into the other flange through the bolt hole of the packing, and tighten the nut. At this time, in order to ensure a sufficient sealing property, it is necessary to carefully tighten the packing with a nut until the packing is appropriately and evenly compressed.

ることを課題とするものである。However, in general, since the packing must be tightened depending on the feeling, it is inevitable that the packing is secured on the safe side, that is, excessive compression. The elastic material such as rubber that constitutes the packing becomes fragile when left in a compressed state above a certain value (above the elastic limit) for a long period of time, and loses elasticity and becomes in a tattered state. In such a state, the sealability may be impaired due to cracks or the like, and an accident such as water leakage may occur. Further, it is difficult to uniformly tighten the plurality of bolts, and therefore, the packing is biased into a compressed state and sufficient sealing performance cannot be obtained. Therefore, it is an object of the present invention to provide a packing structure that can be compressed at a constant compression rate and uniformly even when a normal fastening tool is used.

The plurality of hard compression limiting pieces 3 are spaced apart from each other in the circumferential direction, and are buried in a shorter length than the thickness of the packing 1, leaving a packing compression margin of the packing 1. When the packing structure of the present invention is arranged between the flange surfaces, and the bolt is passed through and tightened with the nut to compress, the packing is kept above a certain level due to the stopper action by the plurality of compression limiting pieces embedded in the circumferentially spaced relationship. Is restricted to being compressed. Therefore, by tightening the plurality of bolts to the limit, the packing is uniformly compressed with an appropriate compression rate that can sufficiently secure the sealing property. In the preferred embodiment of the present invention, the compression limiting piece 3 is a cylindrical body made of metal or hard plastic, and is embedded so that the axial direction of the cylindrical body coincides with the thickness direction of the packing 1. More preferably, the compression limiting piece 3 is embedded in the packing 1 at the outer peripheral portion of the bolt hole 2.

In these figures, the packing 1 is formed in a ring shape by using a resin-based elastic material such as natural or synthetic rubber or fluorine resin, and a plurality of (four in this example) bolt holes 2 are formed in the circumferential direction.

孔４内に接着固定することもできる。The compression limiting piece 3 is made of a material such as a metal or a hard plastic material having a rigidity that does not self-destruct with a normal bolt fastening force. The shape of the compression limiting piece 3 is preferably a cylindrical shape as shown in the drawings from the viewpoint of structure and operation, but other shapes such as a prismatic shape or a truncated cone shape may be used. In any case, the cross-sectional area of the compression limiting piece 3 parallel to the flange surface when embedded may be smaller than that of the bolt hole 2, and when tightening the pair of flanges with a fastener, the tightening force It suffices to have a cross-sectional area that can withstand the above. The required cross-sectional area depends on the strength of the material of the compression limiting piece 3. In addition, the number may be at least three or more, and they are embedded at equal intervals in the circumferential direction. The compression limiting piece 3 is press-fitted and embedded in the hole 4 provided in the packing 1, but may be insert-molded at the time of manufacturing the packing. In addition, in the case of press-fitting, it is possible to bond and fix the inside of the hole 4 with an adhesive or the like.

周側とすることが好ましい。In the process of tightening the packing 1 as a whole with bolts, the tightening stress is concentrated on the bottom 4a of the hole 4 by the stopper action of the compression limiting piece 3, and the bottom 4a of the hole 4 is compressed before it reaches the compression limit. Reach Therefore, the thickness t of the bottom portion 4a is set to a value such that when it reaches the compression limit, the sealability of the packing 1 can be sufficiently secured by the compression of the other portions. Usually, the pipe having a diameter of about 25 mm to 1000 mm is generally widely used, and the packing has a thickness of about 3 mm to 5 mm. And the tightening margin of packing is 1mm-2
Since a thickness of about mm is suitable, the thickness of the bottom portion 4a may be determined according to the optimum tightening margin of each pipe. Next, according to an experiment conducted by the present inventor, in a normal rubber packing, for example, a packing having a thickness of 5 mm has a tightening margin of about 2 mm, so that it is suitable that the thickness t of the bottom portion 4a is about 2 mm. It was Further, the position of the hole 4 in the packing 1, that is, the position where the compression limiting piece 3 is embedded, is preferably on the outer peripheral side of the bolt hole 2 in order to make the stopper action at the time of compression more effective.

There is. As shown in FIG. 4, the bottom portion 4a of the hole 4 is compressed to the compression limit, and in that state, the packing 1 is compressed to a value that can sufficiently secure the sealing property as a whole.

2 is provided, and the cylindrical compression limiting piece 3 is fitted and held in the through hole 12 by press fitting. The compression limiting piece 3 can be fixed in the through hole 12 with an adhesive if desired. The thickness of the packing 1 and the length of the compression limiting piece 3 are the same as in the case of FIG.
The length t of the remaining space is the same as the thickness t of the bottom 4a in FIG. Therefore, the compression limiting piece 3 in this example also operates similarly to the case of FIG. In this example, the packing 1 portion has no portion that is compressed to the elastic limit.

利用でき、取扱いが簡単である。According to the packing structure of the present invention constructed as described above, when the packing is interposed between the flange surfaces of the pipes and tightened by the bolts and nuts and compressed, when compressed by an appropriate compression margin, A plurality of compression limiting pieces, which are spaced apart from each other in the circumferential direction of the packing, serve as stoppers against compression, whereby the packing is restricted from being compressed more than a certain amount. Therefore, by tightening the plurality of bolts to the limit, the packing can be evenly compressed at an appropriate compression rate that can sufficiently secure the sealing property. Thereby, a piping structure having a long life can be laid. Moreover, since the compression limiting piece is embedded in the packing itself, no new parts are required at the work site of the piping, and it can be used as it is for the flange of the conventional piping, and the handling is easy.
