Abstract
The utility model discloses a D shape PVC drain pipe, including PVC pipe body, the body includes PVC pipe layer and sun -proof layer, transversal personally submitting " D " the type of PVC pipe body, the arch section and the line of centres of pipe appear fan -shapedly, sectorial both sides form a contained angle alpha, the fillet transitional coupling is passed through to convex partial and the straight line shape part of PVC pipe body. The utility model relates to a D venturi tube, expose convex position in by force when using external, assurance pleasing to the eye, just the utility model discloses the pressure that its anti vertical centerline of C venturi tube was compared to the D venturi tube is stronger, the utility model discloses with PVC pipe design becoming D venturi tube for the straight -line portion of D venturi tube sets up in wall or underground, and this PVC pipe can not rotate at will, need not manage the pillow yet and fix, has reduced the cost, has reduced the engineering time yet, has improved economic benefits.
Description
Technical field
The utility model relates to a kind of pvc pipe, particularly a kind of PVC drain pipe of D shape.
Background technology
Current PVC drain pipe major part is circular tubing, in use need to add extra pipe pillow, or need to add the fastening devices of additionally adding and preventing PVC pipeline from rolling, PVC drain pipe road is when being used in mansion and being outside in addition, can compare to take up space and unsightly if PVC drain pipe to be made square pipe.Disclose a kind of C shape PVC in China's patent 200720198932.7, this tubing is mainly used in the protection of cable, and lid tubing is provided with breach along its pipe shaft direction on the face of cylinder; but as gutter; if this breach should be arranged at wall, then current can corrode body of wall for a long time, if be arranged at underground; breach is downward; do not reach drainage effect, by breach upwards, then on the ground hedge does not have the strong point easily to loosen to fall into pipeline; and its firmness is also not all right, easily breaks under stress.
Utility model content
The utility model, for overcoming the deficiencies in the prior art, provides a kind of D shape PVC drain pipe.
For achieving the above object, the utility model adopts following technical scheme:
A kind of D shape PVC drain pipe, comprise pvc pipe body, described body comprises pvc pipe layer and sun-proof layer, and the cross section of described pvc pipe body is in " D " type, and the arch section of described pipe and the line of centres present fan-shaped, described fan-shaped both sides shape α in an angle; The circular arc shaped portion of described pvc pipe body is connected by round-corner transition with rectilinear segments.
Further, described α angular region is 60-180 °.
Hinge structure, the beneficial effects of the utility model are:
The utility model design D shape pipe, is exposed to external by force in use by circular arc position, guarantee attractive in appearance; And C shape compared by the utility model D shape pipe, and to manage the pressure of its resistance to vertical center line stronger; Pvc pipe design is become D shape pipe by the utility model, and make the straight line portion of D shape pipe be arranged at wall or underground, this pvc pipe can not arbitrarily rotate, and does not also need pipe to rest the head on fixing, decreases cost, decrease engineering time, improve economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of D shape PVC drain pipe described in the utility model one embodiment.
Reference numeral
1-body; The sun-proof layer of 2-; 3-PVC tube layer; 4-enlarging; 41-non-flared; 5-end; 6-angle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to manual word to make those skilled in the art.
A kind of D shape PVC drain pipe, comprise pvc pipe body, described body comprises pvc pipe layer 4 and sun-proof layer 3, and the cross section of described pvc pipe body is in " D " type, and arch section 1 and the line of centres of described pipe present fan-shaped, described fan-shaped both sides shape α in an angle; The circular arc shaped portion 1 of described pvc pipe body is connected by fillet 5 transition with rectilinear segments 2.
Described α angular region is 60-180 °.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in manual and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
