本考案は軸方向に開口した断面Ｕ字型シールリ
ングの溝内にバネ部材を納めた複合パツキングの
改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a composite packing in which a spring member is housed in a groove of a U-shaped cross-section seal ring that is open in the axial direction.

確保する場合がある。 In packing that uses Teflon or the like as a sealing material, as shown in Fig. 4, a spring member B with a V-shaped cross section is housed in a groove of a seal ring A with a U-shaped cross section that opens in the axial direction. The inner and outer sealing surfaces of seal ring A are
Sealing surface pressure between a 1 and a 2 (protrusions) and the surface to be sealed may be ensured.

材を上記シールリングの溝内に納める際のバネ部
材の環状化が容易である。 As a spring member in such composite packing, a metal wire 1' is bent into a zigzag shape to form a band-like body b as shown in FIG. If the spring member is bent at the center of its width to form a V-shaped cross section, it will be easy to annularize the spring member when the spring member is housed in the groove of the seal ring.

されることになり、シール上不利である。 However, in such a spring member, the inner surface of the seal ring is only pressurized by the zigzag folded parts 3', 3'... shown in FIG. 4', 4', . . ., there is no pressurization of the inner surface of the seal ring, so the above-mentioned seal surface pressure is applied intermittently in the circumferential direction of the seal ring, which is disadvantageous in terms of sealing.

らに、シールリングのシール面部を厚肉にすると
いうことは高価なテフロン等の使用量が増加し、
パツキングの高コスト化が避けられない。 Such disadvantages can be substantially eliminated by reducing the zigzag pitch l in FIG. 1 or by increasing the thickness of the sealing surface of the seal ring. However, in the method of reducing the pitch l, since wire rods are used densely, there is a limit to how much the spring stiffness of the spring member can be reduced, and it cannot be applied to packing that requires small spring stiffness, and the amount of wire rods used is This also increases the cost of packing. Furthermore, making the sealing surface of the seal ring thicker increases the amount of expensive Teflon and other materials used.
The high cost of packing is unavoidable.

とするものである。 The composite packing according to the present invention has a structure that can solve the above-mentioned difficulties, and is made by bending a band-like body formed by bending a metal wire material in a zigzag shape at the center of its width. In a composite packing in which the V-shaped part is housed in a groove of a seal ring having a substantially U-shaped cross section and opened at , with both ends of the V-shaped part being locked to both ends of the groove of the seal ring, the spring member adjacent to the spring member is It is characterized in that the interval between the zigzag folded parts is narrower than the folded width of the zigzag folded parts.
以下、図面により本考案を説明する。 The present invention will be explained below with reference to the drawings.
第３図Ａは本考案において使用するバネ部材の

望ましい。 FIG. 3A shows the shape of the spring member used in the present invention before final molding, in which the metal wire 1 is bent into a zigzag shape, and the distance f between the adjacent zigzag folded parts 2 is adjusted between the folds of the zigzag folded parts 2. It is narrower than the width d and is formed into a band-like body. It is desirable that the distance f be a minute distance such that the wires are substantially in contact with each other.
上記においてジグザグ折返部２の形状は円弧形

1 and small circular arc bent portions 32, 32 may be used. The band-like body shown in FIG. 3 is further molded into a V-shaped cross section as shown in FIG. 2 to produce a spring member.

A2とから構成されている。 In Fig. 4, A is approximately U opened in the axial direction.
It is a Teflon sealing ring with a shaped cross section, consisting of a web part A0 , an inner flange part A1 , and an outer flange part.
It consists of A 2 .

This is a protrusion for locking a spring member provided on the circumferential surface of the surface and the outer flange portion A 2 and on the back surface of the seal surface portions a 1 and a 2 .

Since this is very small, sealing surface pressure can be applied almost continuously to the sealing surface portion (protruding portion) of the seal ring along the circumferential direction. In particular, in the case of FIG. 3B, since the linear portion 2 can be placed directly below the sealing surface portion, the continuity can be made higher than in the case of FIG. 3A, which is preferable. Further, even if the width of the folded portion is increased to some extent, the above continuity can be ensured.
このように、本考案に係る複合パツキングは上

の小さいパツキングも提供することができる。 As described above, since the composite packing according to the present invention has the above-mentioned structure, it is possible to apply pressure almost continuously to the inner surface of the sealing surface portion without reducing the zigzag pitch of the wire rod. Unlike the case where the seal ring is made of expensive Teflon or the like, the sealing surface of the seal ring can be made thinner, and there is no need to increase the amount of wire used, so the packing can be manufactured at a low cost. Furthermore, since the spring rigidity of the spring member can be maintained low, it is also possible to provide packing with low sealing surface pressure.
