Abstract
The utility model relates to a kind of PVC pipeline linkage structure, be provided with bellmouth structure end, socket end, described bellmouth structure end is one be provided with the structure end expanded in one end of PVC pipeline, locking element and rubber sealing part is provided with in the described structure end expanded, described locking element is the locking of the inside with a tooth engaged metal crimp ring, safeguard structure layer is provided with between described inside locking metal crimp ring and bellmouth tube wall, described rubber sealing part adopts the special cushion rubber with sealing, described socket end can be inserted in bellmouth structure end, and locked by inner locking metal crimp ring, sealed by special cushion rubber.The utility model is applicable to PVC pipeline and connects, and has design science, rational in infrastructure, intensity is high, advantage that sealing is strong, easy for installation.
Description
Technical field
The utility model belongs to a kind of PVC, particularly a kind of PVC of bellmouth structure.
Background technique
The Placement of pvc pipe mainly contains O-ring seal, bonding and Flange joint 3 kinds.The pipeline that caliber is more than or equal to 100 millimeters generally adopts rubber gasket; The pipeline that caliber is less than 100 millimeters then generally adopts bonded joint, the employing union also had.Pipeline is when crossing over sewerage or other pipelines, and generally all use metal tube, at this moment plastic tube and metal tube adopt Flange joint.Also be all adopt Flange joint with the connection of pipeline before and after valve.
Current China PVC cushion rubber Placement mainly adopts the mode of rearmounted cushion rubber to connect, namely cushion rubber is built in enlarging place before connecting at the construction field (site) by tubing, carry out pipeline connection again, cushion rubber torsional deformation or dislocation is easily caused in the method implementation process, thus make joint sealing poor, even leak.
Model utility content
The purpose of this utility model is to solve the problem, and proposes a kind of PVC pipeline linkage structure, the feature that this PVC pipeline linkage structure has design science, rational in infrastructure, intensity is high, sealing is strong, easy for installation.
The purpose of this utility model is achieved through the following technical solutions: PVC pipeline linkage structure, be provided with bellmouth structure end, socket end, it is characterized in that: described bellmouth structure end is one be provided with the structure end expanded in one end of PVC pipeline, locking element and rubber sealing part is provided with in the described structure end expanded, described locking element is the locking of the inside with a tooth engaged metal crimp ring, safeguard structure layer is provided with between described inside locking metal crimp ring and bellmouth tube wall, described rubber sealing part adopts the special cushion rubber with sealing, described socket end can be inserted in bellmouth structure end, and locked by inner locking metal crimp ring, sealed by special cushion rubber.
The utility model is in internal lock stressed joint, simple to operate, easy construction, can reduce by the labour force of 30 times, superpower connection feature makes it can as the better selection of trenchless technology, enough intensity bears any pulling force, obstacle and over distance pulling force, can be effectively applied to the occasion of high water level occasion and acid soil; After the connection of tubing socket joint, inner locking metal crimp ring is positioned at the inside of joint, and outside has safeguard structure, thus ensure that inner locking metal crimp ring can not be subject to the contact of fed sheet of a media and external environment condition, thus the Long Service Life of inner locking metal crimp ring can be ensured.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: see accompanying drawing 1, PVC pipeline linkage structure, be provided with bellmouth structure end 1, socket end 2, described bellmouth structure end is one be provided with the structure end expanded in one end of PVC pipeline, locking element and rubber sealing part is provided with in the described structure end expanded, described locking element is the locking of the inside with a tooth engaged metal crimp ring 4, safeguard structure layer 3 is provided with between described inside locking metal crimp ring and bellmouth tube wall, described rubber sealing part adopts the special cushion rubber 5 with sealing, described socket end can be inserted in bellmouth structure end, and locked by inner locking metal crimp ring, sealed by special cushion rubber.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
