Abstract
A wound gasket includes a basic form, wherein the basic form includes a filling belt and a metal belt which are alternately wound into a ring. The wound gasket also includes an inner ring and a filter screen, wherein the inner ring is arranged on the inner side of the basic form, and the filter screen encloses the inner circle of the inner ring. The wound gasket can filter fluid through the filter screen, so as to prevent a sealed part from being blocked.
Description
(1) technical field
The utility model relates to a kind of wound gasket.
(2) background technique
Wound gasket generally comprises the basic model between interior ring, outer shroud, interior ring and the outer shroud.Basic model is the ring that metal tape and filling tape alternately enclose coiled.The occasion that is applied to the flange connection that wound gasket is more.The shortcoming that existence is paid somebody's debt and expected repayment later in existing winding is: easily produce obstruction in sealing part.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing wound gasket, the utility model provides a kind of wound gasket that has filter screen that is difficult in the sealing part obstruction.
The technical scheme in the invention for solving the technical problem is: a kind of wound gasket, comprise basic model, and described basic model comprises filling tape and metal tape, described metal tape and filling tape alternately enclose the coiled ring; Also comprise interior ring, be located on the inboard of described basic model in described, also comprise filter screen, the interior circle of ring in described filter screen sealing is described.
Further, described filter screen sticks on the surface of described interior ring.Perhaps: the inner side surface of ring is provided with a circle crack in described, and the edge of described filter screen is clamped in the described crack.
Further, the outer shroud that also comprises the outside of being located at described basic model.
The beneficial effects of the utility model are: can filter by the filter screen convection cell, prevent to stop up in sealing part.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of wound gasket comprises basic model, and described basic model comprises filling tape 1 and metal tape 2, and filling tape 1 adopts graphite tape in the present embodiment.Described metal tape 2 and filling tape 1 alternately enclose the coiled ring; Ring 3 in also comprising, described interior ring 3 is located at the inboard of described basic model; Also comprise outer shroud 4, described outer shroud 4 is located at the outside of described basic model; Also comprise filter screen 5, the interior circle of ring 3 in described filter screen 5 sealings are described.In the present embodiment, the inner side surface of described interior ring 3 is provided with a circle crack, and the edge of described filter screen 5 is clamped in the described crack.Certainly filter screen 5 also can other forms be provided with the surface that filter screen Pasting as described encircles in described.
