に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention mainly aims to increase the durability of the packing by providing a peripheral wall on the side periphery of the packing, and to ensure a constant tightening amount by tightening the packing using the height of the peripheral wall as a stopper. This invention relates to a packing with a peripheral wall that aims to achieve a strong tightening state by connecting the entire structure including the packing via a highly rigid peripheral wall.

増大が期待できる。Conventionally, the side periphery of the packing may be left exposed when the packing is tightened, but depending on the operating temperature or the object of use, a surrounding wall may be installed to protect the side periphery of the packing. By doing so, it can be expected that the durability of the packing will increase.

の全体が同時に締め付けられ最終締付け状態に達する。The present invention has been improved from the viewpoint of the tightening state of the conventional gasket, and to explain it with reference to the drawings, the plate of the inner frame (2) of the elastic body and the plate of the outer frame (3) of the elastic body are improved. In the middle, the body of the packing (1) whose thickness is greater than these boards
This is a packing with a peripheral wall that is constructed by combining the following parts as shown in Fig. 3. When tightening the packing with the peripheral wall, the main body (1) of the packing is first tightened by a certain initial tightening amount. Next, the main body of the pack (1
) becomes equal to the thickness of the plate of the inner frame (2) of the elastic body or the plate of the outer frame (3) of the elastic body, and the entire packing with the rear peripheral wall is simultaneously tightened to reach the final tightened state.

量が最終締付け量とみなされる最終締付け状態となる。In this case, the plate of the inner frame (2) of the elastic body or the plate of the outer frame (3) of the elastic body is in the final tightened state.
If the rigidity or tightening area is so large that only a negligible change occurs with respect to a constant initial tightening amount of It acts as if it were a stopper, and the main body (1) of the seal enters a final tightening state in which a certain initial tightening amount is regarded as the final tightening amount.

態に達する。Therefore, even if you tighten with excessive tightening force, the body of the gasket (
Regarding 1), the final tightening amount is set at a constant initial tightening amount corresponding to the difference between the thickness of the inner frame (2) of the elastic body or the outer frame (3) of the elastic body and the thickness of the packing body (1). The tightening state is reached.

締付け状態に達する。FIG. 7 shows a packing with a peripheral wall, which is constructed by combining the outer peripheral part of a plate of an inner frame (2) of an elastic body with a main body (1) of the packing which is thicker than the plate. In this case, after the main body (1) of the seal is tightened by a certain initial tightening amount, the plate of the inner frame (2) of the elastic body acts as a stopper, and the main body (1) of the packing is tightened to a certain initial tightening amount and then to the final tightening state. reach.

の締付け状態で最終締付け状態に達する。Figure 6 shows a packing with a peripheral wall, which is constructed by combining the main body (1) of the packing, which is thicker than the depth of the groove, into the grooves formed on both sides of the plate of the integral frame (4) of the elastic body. It is. In this case, after the main body (1) of the packing is tightened by a certain initial tightening amount, the integral frame (1) of the elastic body (
The plate 4) acts as a stopper and reaches the final tightening state after a certain initial tightening amount.

。The above-mentioned packing with a peripheral wall can obtain a final tightened state with a constant tightening amount, which is advantageous in solving the problem of local leakage, which is important for the function of the packing. In addition, as shown in FIG. 8 or 9, regarding the tightening state between the structure (5) and the structure (6), the main body (1) of the gasket is held in the tightened state with a certain initial tightening amount, and the elastic A strong tightening state can be achieved through the plates of the inner frame (2) of the body, the plates of the outer frame (3) of the elastic body, or the plates of the integral frame (4) of the elastic body.

）を撰択した周壁付きパツキンが考えられる。The characteristics of the final tightened state of the packing body (1) are as follows:
Since the main body (1) of the packing is assembled in a sealed state as shown in FIG. 8, it can be stably applied even when the main body (1) of the packing is thick and soft. In this case, the packing with the peripheral wall can have the shape characteristics of an O-ring tightened in a closed space, so the fourth
The main body of the gasket (1
) can be considered as a packing with a surrounding wall.

利である。For example, when it is necessary to use an expensive material such as silicone rubber as the material of the packing body (1),
In a packing with a peripheral wall as shown in the figure, an integral frame of elastic material (4
) It is advantageous in terms of material costs because expensive materials need only be applied to the main body (1) of the packing except for the plate part.
