する方法が採られている。 More specifically, the present invention relates to a coil packing made of organic or inorganic fiber threads formed into a string shape with a rectangular cross section by braiding methods such as eight braids, lattice stitches, and bag stitches. Normally, coil packing is used by cutting it appropriately according to the dimensions of the gland part, but when filling the gland part with it, the cut parts are butted together to form a ring shape, and the butted parts are alternately shifted. However, a method is adopted in which a suitable number of containers are stacked and filled.

伝つて漏洩するという欠点がある。 However, if the ground part is filled with such a coil packing in the form of a ring, the results shown in Figs.
As shown in Fig. 5, the outer circumferential side of the coil packing a
Since a′ is stretched and the inner circumferential side a″ is compressed, the cross-sectional shape of the main body becomes a trapezoid with a narrow outer diameter and a wide inner diameter. Therefore, when multiple coil packings are stacked together, A gap t is created on the outer periphery.As these gaskets are tightened, the tightening starts from the inner diameter side a'', and when the outer diameter side a' reaches an appropriate tightening force, conversely, the inner diameter side a'' tightens. Excessive tightening. Especially if such a coil packing is used on the rotating shaft of a pump, the life of the coil packing will be shortened due to wear and heat generation of the shaft and packing.In some cases, the tightening force of the packing is insufficient. As shown in the direction of the arrow in FIG. 4, there is a drawback that the internal fluid leaks through the gap t on the outer periphery of the packing and the abutting portion 3 of the packing.

くおさえることができる。 4 is a square yarn, and yarns such as cotton yarn, asbestos yarn, carbon fiber yarn, etc. are arranged at four intervals to maintain the cross section of the coil packing in a square shape. 5 is a core material placed in the center of these square yarns, and 6 is a braided yarn made of asbestos yarn, carbon fiber yarn, tetrafluoroethylene resin yarn, etc., which is braided into a lattice pattern to form a string with a square cross section. This is a molded coil packing A. Reference numeral 7 designates small knob-shaped protrusions formed at appropriate intervals at the corners of the coil packing A. To form this knob-shaped small protrusion 7, thick knots are provided in the square thread 4 or the braided thread 6, and these knots are arranged so that the knots are placed at the corners of the coil packing A when braided. They are sequentially provided at predetermined positions on square threads or braided threads. Alternatively, a method may be adopted in which a core made of the various coil packing materials described above is inserted into the location where the knob-shaped small protrusion 7 is located, and the core is inflated into a knob-shape.
It goes without saying that the materials for the knots, cores, etc. that form these small protrusions 7 may be the same or different from those of the square yarn 7 and the braided yarn 6, depending on the conditions of use. If the coil packing wears out relatively quickly, such as when attached to the gland, a soft material such as tetrafluoroethylene resin or carbon fiber is used; if it is to be used for a long period of time, a flexible material such as asbestos is used. It is preferable to use a material with good properties. In the embodiment, the knob-shaped small protrusions 7 are provided on the inner and outer peripheries of the coil packing, but they may be provided only on the outer periphery. As described above, the coil packing according to the present invention has small bump-like protrusions formed at appropriate intervals on the corners of the string-like coil packing with a rectangular cross section. The small knob-like protrusion is crushed between the overlapping packing body and the gap t formed on the outer periphery is closed at an appropriate interval. As a result, the internal fluid does not leak to the outside through the gap t created on the outer periphery of the packing body, unlike in the conventional case. Moreover, when the coil packing of the present invention is applied to the gland of a pump, etc., the initial adjustment at the time of installation does not have to be tightened more than necessary, unlike conventional methods, so there is little wear resistance, preventing seizure on the shaft and preventing shaft rotation. Torque can be kept low.

Furthermore, using a single coil packing is advantageous in terms of maintenance, as the work and maintenance when replacing the packing becomes easier. Furthermore, if a similar spiral spacer ring 8 is inserted between the spiral-shaped coil packing bodies as shown in Figure 3, it will prevent leakage from penetrating into the coil packing and at the same time prevent leaked fluid from flowing around the circumference of the coil packing. Since it moves, the distance the leaked fluid moves becomes longer, and the length of the gland part can be reduced.
