Abstract
The utility model discloses a kind of cast iron pipe straight tube connectors, including inner tube and outer tube, inner tube is inserted in outer tube, and it is recessed inwardly in the position inner tube lateral surface of grafting, the medial surface of outer tube then outwardly convex makes inner tube with outer tube in the o-ring groove that the position Formation cross-section of grafting is V-shaped, and the both sides of V-shaped o-ring groove accompany a circle rubber seal respectively, the outside of inner tube and outer tube plugging position then welds together, and welding position forms welded seal ring.The utility model has the beneficial effects that further increasing the peel ability between flange, conduit coupling, there is secondary soft seal if even if weld cracking occur, be not in drainage.
Description
Technical field
The utility model is related to a kind of connector, specifically a kind of cast iron pipe straight tube connector.
Background technology
Current cast iron pipe straight tube is attached using welding flange, and during long-term use, welding connects
Easily there is splitting for weld seam in the position connect, and the weld seam being welded to connect is caused leak occur.
Invention content
To solve the above problems, the purpose of this utility model is to provide a kind of cast iron pipe straight tube connector.
The utility model to achieve the above object, insert by cast iron pipe straight tube connector, including inner tube and outer tube, inner tube
Be recessed inwardly in outer tube, and in the position inner tube lateral surface of grafting, the medial surface of outer tube then outwardly convex, make inner tube with
For outer tube in the o-ring groove that the position Formation cross-section of grafting is V-shaped, the both sides of V-shaped o-ring groove accompany one respectively
Rubber seal is enclosed, the outside of inner tube and outer tube plugging position then welds together, and welding position forms welded seal ring.
Prevent outer tube or ring flange from slipping using V-shaped face in contact surface by arrangement above, and contact surface uses
Rubber seal carries out secondary seal, achievees the purpose that straight tube junction security seal during use.
The utility model has the beneficial effects that：The peel ability between flange, conduit coupling is further increased, i.e.,
Make weld cracking occur, also there is secondary soft seal, is not in drainage.
Description of the drawings
The utility model is described further in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, cast iron pipe straight tube connector, including inner tube 1 and outer tube 2, inner tube 1 are inserted in outer tube 2,
And be recessed inwardly in 1 lateral surface of position inner tube of grafting, the medial surface of outer tube 2 then outwardly convex makes inner tube 1 and outer tube 2
In the o-ring groove 3 that the position Formation cross-section of grafting is V-shaped, the both sides of V-shaped o-ring groove 3 accompany a circle rubber respectively
Glue sealing ring 4, inner tube 1 and the outside of 2 plugging position of outer tube then weld together, and welding position forms welded seal ring 5.
The above descriptions are merely exemplary embodiments of the present utility model, is not limited to the model of the utility model
It encloses.Any those skilled in the art, made equivalent change under the premise of not departing from the design and principle of the utility model
Change and change, the range of the utility model protection should all be belonged to.
