Description
Technical field
The utility model belongs to tubing technical field, is specifically related to a kind of being easy to using the close pipe with connection of Push-fit
Material, is mainly used in the fields such as municipal drainage pipe, industrial and mineral ventilation duct.
Background technology
For the tubing in the fields such as municipal drainage, industrial and mineral ventilation, limited with construction site due to being transported by road, generally
Linked into an integrated entity by some tubing socket joints.With the progress of plastic pipe technology, plastic pipe is applied in above-mentioned field must be got over
Come more extensive.The mode that is tightly connected of current plastic pipe typically has sealing ring connection, flange connection or electric melting connection,
The pipeline construction scene in the fields such as municipal drainage, industrial and mineral ventilation, plastic pipe of the prior art is tightly connected mode and is subject to very
Big limitation, such as sealing ring connected mode, construct very laborious, it is easy to damage tubing；Such as flange connection, it is necessary to
Larger construction space；Such as electric melting connection mode, it is desirable to which construction site is more dried, in the feelings on moist or rainy day
Cannot be constructed under condition.
A kind of " throttle type socket joint is without pad connection tubing " (patent No.：201310250854.0, the applying date：
2013.06.21), a kind of new bell and spigot frame of plastic pipe is described, is fitted close using annular ring and is caused tubing close with even
Connect, the tubing being connected using spacing collar and annular groove cooperation secondary locking phase socket joint.Tubing is to the close-fitting essence of annular ring
Degree requires higher, slightly mistake, or annular ring interference fit, tubing socket joint is very laborious, and damage is easy in work progress
Tubing, efficiency of construction is low, and construction cost is higher；Annular ring gap coordinates, and tubing can not be close with connection, it is difficult to reaches and applies
The design requirement of work.In socket joint connection procedure, with the increase for being fitted close annular ring, construction is more and more laborious, and spacing collar
The secondary locking design coordinated with annular groove undoubtedly again increases difficulty of construction in the rear of socket joint connection procedure, or even
Spacing collar fails to set into annular groove, loses the purpose of design of secondary locking.
