Abstract
The utility model provides a kind of pvc pipe mouth attachment structure, including bellmouth structure section, outlet structure section, and described bellmouth structure section internal diameter is more than internal diameter of tube body, and bellmouth internal diameter sets recessed grain, and groove is trapezoidal groove, and the width close to tube wall is less than close to caliber width；Outlet structure internal diameter is identical with internal diameter of tube body, and jack surfaces set projection, and projection is trapezoidal projection, is more than close to internal diameter side wall ledge width close to caliber center width；Described groove and described ledge width and highly identical, the bellmouth internal diameter is identical with socket external diameter.The beneficial effects of the utility model are：The sealing of mouth of pipe junction is added by the utility model.
Description
Technical field
The utility model belongs to pvc pipe mouth tubing, specially a kind of pvc pipe mouth attachment structure.
Background technology
The connected mode of PVC drain pipe material mainly has O-ring seal, bonding to connect 3 kinds with flange.Different installation situations will
There is different connected modes, pipeline of the PVC drain pipe caliber more than or equal to 100 millimeters typically uses rubber gasket；PVC drain pipe
Pipeline of the caliber less than 100 millimeters then typically uses bonded joint, and also some uses articulation；PVC drain pipe pipeline is being crossed over
When sewer or other pipelines, metal tube is typically all used, at this moment plastic tube is connected with metal tube using flange, but these are passed
The attachment structure sealing of system is poor, or even leakage.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of pvc pipe mouth attachment structure.
The technical solution of the utility model is pvc pipe mouth attachment structure, including bellmouth structure section, outlet structure section, described
Bellmouth structure section internal diameter be more than internal diameter of tube body, bellmouth internal diameter sets recessed grain, and groove is trapezoidal groove, and the width close to tube wall is small
In close to caliber width；Outlet structure internal diameter is identical with internal diameter of tube body, and jack surfaces set projection, and projection is trapezoidal projection, is leaned on
Nearly internal diameter side wall ledge width is more than close to caliber center width；Described groove and described ledge width and highly identical,
The bellmouth internal diameter is identical with socket external diameter.
Further, the bellmouth structure section number of recesses is identical with outlet structure section projection quantity, is distributed position in the mouth of pipe
Put identical.
Further, the groove and raised width edge length are the 1/10 of internal diameter of tube body.
Further, described number of recesses is 3, and mean allocation is in bellmouth internal diameter.
A kind of pvc pipe mouth attachment structure of the utility model, compared with prior art with advantages below：By groove and convex
Play that fitted seal is strong, and groove and bulge-structure use trapezium structure, add cooperation intensity and sealing, width and quantity
Design has disperseed fluid by stress herein, increases connective stability.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
In order to be better understood from the utility model, enter traveling one to the utility model with reference to specific embodiments and the drawings
The description of step.
The technical solution of the utility model as shown in Figure 1 is pvc pipe mouth attachment structure, including bellmouth structure section 1, socket
Structural sections 2, the described internal diameter of bellmouth structure section 1 are more than internal diameter of tube body, and bellmouth internal diameter 1 sets recessed poor 3, and groove 3 is trapezoidal groove,
Width close to tube wall is less than close to caliber width；The internal diameter of outlet structure 2 is identical with internal diameter of tube body, and jack surfaces set projection 4,
Projection 4 is trapezoidal projection, is more than close to internal diameter side wall ledge width close to caliber center width；Described groove 3 and described
Raised 4 width and highly identical, the internal diameter of bellmouth 1 is identical with the external diameter of socket 2.
The quantity of 1 groove of bellmouth structure section 3 and the raised amount of number 4 of outlet structure section 2 are identical, in mouth of pipe distributing position phase
Together.
Groove 3 and raised 4 width edge lengths are the 1/10 of internal diameter of tube body, and depth is the 2/3 of tube wall, and width is too small to be played
Sealing function, mismatched with depth greatly very much.
The quantity of groove 3 is 3, and for mean allocation in bellmouth internal diameter, the angle of each two groove 3 is 120 °.
Embodiment of the present utility model is described in detail above, but the content is only of the present utility model preferable
Embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.All impartial changes made according to the scope of the utility model
Change and improvement etc., all should still be belonged within this patent covering scope.
