Abstract
The utility model provides a heavy-caliber plastic pipe expansion joint which comprises a pipe body, wherein the pipe body is internally provided with an expansion joint, wherein one end part at one end of the expansion joint extends into the pipe body, and the end part at the other end of the expansion joint extends to the outer side of the pipe body; the outer wall of the end part which extends into the pipe body of the expansion joint is provided with two to four sealing grooves; and the sealing grooves are also internally provided with O-shaped sealing rings. The heavy-caliber plastic pipe expansion joint provided by the utility model has the beneficial effects that one end of the pipe body is internally provided with the expansion joint, also the outer wall of the end part where the expansion joint is connected with the pipe body is provided with the sealing grooves, and the sealing grooves are internally provided with the O-shaped sealing grooves, thus not only is the sealing property of the plastic pipe ensured, but also when the external conditions such as temperature change, the pipe body or the expansion joint can move freely, the expansion effect is achieved, and the cracking of a pipeline is prevented effectively.
Description
Technical field
The utility model relates to a kind of heavy-caliber plastic pipe, particularly a kind of heavy-caliber plastic pipe slip joint.
Background technique
Mostly heavy-caliber plastic pipe is the polyethylene material; Segmentum intercalaris connects in adopt the port of plastic tube; Middle segmentum intercalaris is enclosed within the acromere and is welded to connect, because the plastic tube shrinkage is big, can change with variations such as temperature at axial length; In use be easy to fracture occur, influence the proper functioning of pipeline.
The model utility content
Occur the phenomenon that ruptures easily for fear of heavy-caliber plastic pipe, the utility model embodiment provides a kind of heavy-caliber plastic pipe slip joint.Its technological scheme is following: the heavy-caliber plastic pipe slip joint; Comprise body; Wherein, Be provided with one of which end end in the said body and stretch into the slip joint that inner and its other end end of said body extends to the said body outside, the end outer wall that stretches into the inner said slip joint of said body is provided with 2-4 seal groove, also is provided with the O RunddichtringO in the said seal groove.
The outer wall of said slip joint is provided with 3 seal grooves.
The beneficial effect of the utility model is: in an end of body, be provided with slip joint, and the outer wall of the end that is connected with body of slip joint is provided with seal groove, is provided with the O RunddichtringO in the seal groove; Like this; Not only guaranteed the sealing of plastic tube, and when ambient conditionss such as temperature changed, body or slip joint can move freely; Reach flexible effect, effectively avoided occurring the fracture of pipeline.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Wherein, reference character is: 1, body; 2, seal groove; 3, O RunddichtringO; 4, slip joint.
Embodiment
