螺旋状に巻付けた密封部材Ｃ等が提供されている。A sealing member C1 is formed by superimposing a net-like reinforcing material B on a tape-like sealing material A made of mica, verminiquirite, porous PTFE, etc. and press-molding it.As shown in FIG. 8, the tape-like sealing material is A sealing member C5 is made by stacking a plurality of linear reinforcing materials B and forming them under pressure.As shown in FIG. A pressure-molded sealing member C and a sealing member C in which a linear reinforcing member B is spirally wound around the tape-shaped sealing material as shown in FIG. 10 are provided.

る低弾性繊維、例えば金属繊維に制約される。However, in this kind of conventional sealing member C, a highly elastic material such as carbon fiber, glass fiber, ceramic fiber, etc. is used as the reinforcing material B to increase the rigidity, and the sealing member C with increased rigidity is thinly wound. Even if an attempt is made to manufacture, for example, a gland packing by winding the fiber into a ring shape and then pressure forming it into a ring shape, the aforementioned fibers used as reinforcing material B are not plastically deformed by pressure forming, so they cannot be formed into a tape-like sealing material. However, the required bonding strength cannot be obtained. Therefore, since the shape retention effect is low and it is not suitable for practical use, the materials that can be used as the reinforcing material B are limited to low elastic fibers that are easily plastically deformed by pressure molding, such as metal fibers.

The objective is to provide a sealing member that can be pressure-molded into a desired shape by increasing the shape retention effect.

高圧用のグランドパツキンとして好適となる。The tape-shaped sealing material 2 is made of a material having excellent flexibility, heat resistance, corrosion resistance, and compression recovery properties, such as expanded graphite, mica, verminyrite, and porous PTFE. A plurality of reinforcing materials 3 (for example, three) are arranged as bobbin threads on the back surface of this tape-like sealing material 2 along the longitudinal direction of the tape-like sealing material 2 and at appropriate intervals in the width direction. There is. This reinforcing material 3 is made of a highly elastic material such as carbon fiber, glass fiber, or ceramic fiber.
This reinforcing material 3 as a lower thread is sewn using a sewing thread 4 made of metal fiber such as stainless steel wire as an upper thread using an industrial sewing machine. By sewing the reinforcing material 3 to the tape-shaped sealing material 2 with the sewing thread 4 in this manner, the bonding strength of the reinforcing material 3 to the tape-shaped sealing material 2 is significantly improved. Therefore, when the sealing member 1 is wound in a spiral shape and then pressure-formed into an annular shape, the reinforcing material 3 can be plastically deformed in the near future without separating from the tape-shaped sealing material 2 due to the large bonding strength. In addition, the resulting sealing member 1 has a high shape retention effect, and is suitable as a gland packing for high temperature and high pressure applications, for example.

The sealing member l is sewn in a meandering manner in the longitudinal direction of the sealing material 2. In this case, similar to the first embodiment, high bonding strength can be obtained, and since the reinforcing material 3 is a metal fiber, its elastic value is smaller than that of the reinforcing material 3 described in the first embodiment. Since plastic deformation is easy, a small-diameter annular packing PI can be pressure-formed as shown in FIG.

The hem is sewn using an industrial sewing machine using a sewing thread 4 made of metal fiber such as stainless steel wire. Even with such a configuration, the bonding strength of the reinforcing material 3 to the tape-shaped sealing material 2 can be increased. For example, by winding the reinforcing material 3 in a spiral shape and then press-forming it into an annular shape, the annular shape shown in FIG. Patsukin P2 can be obtained.

It can be used as a reinforcing material 3.

する。(Effects of the Invention) According to the present invention, the reinforcing material is disposed on the outer surface of the tape-shaped sealing material, and this reinforcing material is sewn to the tape-top sealing material with a sewing thread, so that the tape-shaped sealing material of the reinforcing material is The bonding strength to the material is greatly improved, and even when using a highly elastic material such as carbon fiber, glass fiber, or ceramic fiber as a reinforcing material, it can be press-molded into a desired shape (for example, annular shape). Moreover, a packing with significantly improved rigidity can be obtained without impairing excellent properties such as flexibility, heat resistance, corrosion resistance, and compression recovery. Furthermore, since the reinforcing material is not attached to the tape-shaped seal member using adhesive, there is less heat loss at high temperatures, ensuring high sealing performance, and the improved rigidity reduces the tightening force during use. Since the resulting deformation can be prevented, sealing performance is improved.
