Abstract
The utility model relates to a PVC tubular product with prefabricated formula flaring structure of rubber ring is equipped with PVC tubular product body, a pipe end of PVC tubular product body is the expansion end, two wall thicknesses are greatly held to the diameter ratio of expansion end PVC tubular product body's diameter, the expansion end inner wall is equipped with an annular "font recess", it is "font rubber ring" for having inlayed a cross section in the recess, another pipe end of PVC tubular product body is for inserting the end. The utility model is suitable for a PVC tubular product has design science, rational in infrastructure, intensity is high, the leakproofness is strong, simple to operate's advantage.
Description
Technical field
The utility model belongs to a kind of PVC, particularly a kind of PVC of tool flaring 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, a kind of PVC with cushion rubber prefabricated flaring structure is proposed, this feature that PVC flaring structure with cushion rubber prefabricated flaring 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: the PVC with cushion rubber prefabricated flaring structure, be provided with PVC body, it is characterized in that: a pipe end of described PVC body is for expanding end, described diameter two wall thickness larger than the diameter of PVC body held that expand, the described end inwall that expands is provided with " " font groove of a ring-type, be inlaid with a cross section in described groove for " " font rubber ring, another pipe end of described PVC body is insertion end.
The utility model breaches the cushion rubber Placement of conventional PVC, devise a kind of cushion rubber and be formed on structure in enlarging in advance, namely cushion rubber is directly built in enlarging in flaring process by tubing on a production line, this design makes cushion rubber permanently be fixed in enlarging, enlarging and cushion rubber are molded as one, in pipeline mounting construction process, can not there is any distortion or dislocation in cushion rubber, ensure that the sealing that pipeline connects and Security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: see accompanying drawing 1, there is the PVC of cushion rubber prefabricated flaring structure, be provided with PVC body 1, one pipe end of described PVC body is for expanding end, described diameter two wall thickness larger than the diameter of PVC body held that expand, the described end inwall that expands is provided with " " font groove 2 of a ring-type, and be inlaid with a cross section in described groove for " " font rubber ring 3, another pipe end of described PVC body is insertion end 4.
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.
