Description
Technical field
The utility model relates to a kind of connection set of metallic conduit, specifically is a kind of connection set that is used for the reducing metal tube.
Background technique
At present, the metal tube of two various outer diameters of prior art is to adopt reducer pipe (joint) to connect, and the mode of employing screw thread or welding is connected the metal tube of two various outer diameters with the two ends of reducer pipe.If but when the connection set pipeline that is used for the reducing metal tube of prior art need overhaul because of outside cause, this linkage structure was not easy dismounting again, thereby has brought difficulty to maintenance work.
The model utility content
The technical problems to be solved in the utility model is that a kind of easy-to-dismount connection set that is used for the reducing metal tube is provided.
The technical solution of the utility model is, a kind of connection set that is used for the reducing metal tube is provided, comprise first flange and second flange, the internal diameter of described first flange matches with the external diameter of first metal tube and fixedlys connected, the internal diameter of described second flange matches with the external diameter of second metal tube and fixedlys connected, and described first flange is removable the connection with described second flange; The joint of described first flange and described second flange is provided with seal ring.
After adopting above structure, the utility model compared with prior art has the following advantages:
Because two flanges of the utility model are removable connection, when pipeline ran into outside cause and need overhaul, only two flanges need be dismantled and then loaded onto got final product, thereby provided convenience for maintenance work in the future.In addition, the joint of two flanges of the utility model is provided with seal ring, can strengthen the sealability that the utility model is used for the connection set of reducing metal tube.
Description of drawings
Accompanying drawing is a structural drawing of the present utility model.
1, first flange shown in the figure, 2, second flange, 3, first metal tube, 4, second metal tube, 5, bolt, 6, seal ring.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in drawings, a kind of connection set that is used for the reducing metal tube of the utility model, comprise first flange 1 and second flange 2, it is characterized in that: the internal diameter of described first flange 1 matches with the external diameter of first metal tube 3 and fixedlys connected, the internal diameter of described second flange 2 matches with the external diameter of second metal tube 4 and fixedlys connected, and described first flange 1 is removable the connection with described second flange 2.In the present embodiment, above-describedly be fixedly connected as welding.
Described first flange 1 is provided with seal ring 6 with the joint of described second flange 2, can strengthen the sealability of two flange connections of the utility model.
The described removable bolt that is connected to connects.
