Abstract
The utility model discloses a seal gasket used to isolate gas and prevent explosion, which comprises a ringy case. A ringy groove stuffed with a cushion body for butt joint is arranged on external surface of the ringy case and at least one steel strip is inlaid inside the cushion body. As a combined product with a structure made up of a plurality of metal layers, the waterproof seal gasket isolates coal and does not deform in normal fire and under high temperature, which effectively solves problem that seal gasket of electrical appliances used in mine deforms under high temperature and then gas leaks out.
Description
Technical field
The utility model relates to a kind of sealing mat, relates in particular to a kind of gas in mine flame proof sealing mat.
Background technology
At present, also there is not a kind of special gas in mine flame proof sealing mat on the market.In field of mining, often substitute gas in mine flame proof sealing mat, the at high temperature yielding gas leakage that causes of rubber sheet gasket, the serious accident of mine disaster that also can cause serial blast with some rubber sheet gaskets.
Summary of the invention
The utility model provides a kind of gas in mine flame proof sealing mat, and it can substitute the various problems that are tightly connected of rubber sheet gasket processing of usefulness in the past, has effectively prevented gas leakage.
The utility model can get one by the following technical programs and implement: a kind of gas in mine flame proof sealing mat, it comprises a toroidal shell, has the annular groove of butt joint on the outer surface of described toroidal shell, is filled with pad in the described annular groove.
It is 0.14～0.16cm that place, the inside edge impression of the upper surface of described toroidal shell has impression, the breadth of section of described impression.
Described toroidal shell is annular, side's annular or other specially-shaped annulars.
Described pad inside is embedded with at least one steel band.
Compared with the prior art the utility model has following advantage: described gas in mine flame proof sealing mat, comprise a toroidal shell, described toroidal shell can adopt copper, aluminium, stainless steel etc. to have certain soft metal material, the toroidal shell of making like this has resilience, resistance to compression, anti-coal, characteristic such as fire-retardant, and these characteristics are even more important in this special field of mining; Described pad adopts some nonmetal resistant to elevated temperatures materials more; Be embedded with steel band in the described pad, described steel band can be strengthened the compressive strength of described sealing mat, and this gas in mine flame proof sealing mat of being made up of toroidal shell, steel band, pad is a kind of compound, the product of multi-layer metal structure.Compare with the alternative rubber sheet gasket of former gas in mine flame proof sealing mat, both waterproof again can be every coal, and is indeformable under general fire and high temperature, effectively solved the distortion that mining electrical equipment at high temperature causes because of pad, and then caused the problem of gas leakage.
