Specific implementation mode
In conjunction with shown in Fig. 1 and Fig. 3, the blind plate dismounting of the utility model is made further of pipeline gas detection device
It is bright.
As depicted in figs. 1 and 2, a kind of blind plate dismounting pipeline gas detection device, the device include blind plate 1, gas inspection
Survey instrument 2, connecting conduit 3 and quick coupling 4.Handle 12 and gas port 13 are provided on blind plate 1, handle 12 is arranged in blind plate 1
Side or upper surface, handle 12 is with blind plate 1 by being welded and fixed.Blind plate 1 is cylinder, and gas port 13 connects the side of blind plate
And lower surface, the length of the gas port 13 are less than the radius of upper surface.By the way that gas port 13 is arranged on blind plate 1, and lead
