Abstract
The utility model discloses an injection type plastic double-wall corrugated pipe which comprises a pipe wall with corrugated bulges on the outer wall and is characterized in that a hollow inner pipe is wrapped inside the corrugated bulges. The injection type plastic double-wall corrugated pipe has the following benefit: the double-wall corrugated pipe with the structure can be directly injection molded by adopting a die, and the steel-reinforced plastic double-wall corrugated pipe that is injection molded has the following advantages: 1. high ring stiffness; 2. large pipe diameter which can reach Phi 3000 or even larger; 3. high yield; 4. high production efficiency, i.e., the plastic double-wall corrugated pipe has high pipe producing efficiency when the glue squeezing amount of a squeezing machine is enough; 5. smooth inner wall and small water flow friction, i.e., the plastic double-wall corrugated pipe has smooth pipeline inner wall when compared with wounded type draining pipes; 6. no leakage, i.e., compared with the wounded type draining pipes, the pipe wall of the plastic double-wall corrugated pipe does not have the leakage defect; and 7. capability of being produced to be with flange connection.
Description
Technical field
The utility model relates to the municipal drainage facility, specifically a kind of injection plastic double-wall corrugated pipe.
Background technique
Common extrusion type plastic double-walled corrugated pipe shortcoming is: 1, be subjected to the restriction of extruder head, diameter can not be done very greatly, generally is difficult to exceed φ 1200; 2, ring stiffness is not enough, and pure plastic double-walled corrugated pipe ring stiffness is usually less than SN8, and Ministry of Construction's regulation waste pipe ring stiffness can not be lower than SN8; 3, yield rate is lower, and especially major diameter is produced relatively difficulty such as φ more than 800, and yield rate is low.
The model utility content
The purpose of this utility model is: provide a kind of work efficiency height at the deficiencies in the prior art, ring stiffness height, can machining large-sized caliber, and reliable injection plastic double-wall corrugated pipe easy to connect.
The technical solution of the utility model is:
A kind of injection plastic double-wall corrugated pipe comprises that outer wall is the tube wall of corrugated projection, it is characterized in that the interior pipe of hollow is arranged in the internal package of corrugated projection.
Supplementary technology scheme of the present utility model is as follows:
Preferably, the interior pipe of described hollow is a steel pipe.
Preferably, described interior pipe is the steel pipe of annular hollow, is connected with strut between steel pipe and steel pipe.
The flange that integrated injection molding preferably, is arranged at the injection plastic double-wall corrugated pipe two ends.
Preferably, the sealability in order to connect between the pipe end has the circular groove that seal ring is installed on the exterior edge face of at least one flange.
The beneficial effects of the utility model are: so the double-wall corrugated pipe of structure can adopt the direct molding and forming of mould, and the steel reinforced plastic double-wall corrugated pipe of molding and forming has following superiority:
1. ring stiffness height.
2. caliber is big, and diameter can reach φ 3000. even bigger.
3. yield rate height.
4. manufacturing efficiency height when the plastic squeeze amount of extruder is enough, goes out the tube efficiency height.
5. inner wall smooth, the current frictional resistance is little.Compare with the wrap style waste pipe, inner-walls of duct is smooth.
6. can not leak.Compare with the wrap style waste pipe, tube wall does not have the leakage shortcoming.
7. can make flange and connect convenient and quick construction.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 be the utility model injection plastic double-wall corrugated pipe embodiment partly cut open figure;
Fig. 2 is the schematic representation of interior pipe among the utility model injection plastic double-wall corrugated pipe embodiment:
Fig. 3 is the external mold of processing the utility model injection plastic double-wall corrugated pipe;
Fig. 4 is the internal mold of processing the utility model injection plastic double-wall corrugated pipe.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as shown in Figure 1, a kind of injection plastic double-wall corrugated pipe comprises that outer wall is the tube wall of corrugated projection 3, different with the bellows of existing extruding and moulding, the bellows 1 of present embodiment has the interior pipe 4 of hollow in the internal package of corrugated projection 3.Because the ring stiffness height of steel pipe, and easy processing, a kind of relatively good method is directly to use steel pipe as interior pipe 4.
4 one kinds of preferred modes of above-mentioned interior pipe are to select the steel pipe of annular hollow for use, and are convenient for whole bellows injection molded, are connected with strut 5 between steel pipe and steel pipe.Above-mentioned interior pipe 4 also can select for use the steel pipe of screw type as interior pipe 4.
The utility model injection plastic double-wall corrugated pipe manufacture method is:
The mould of preparation internal mold 7 and external mold 6, as shown in Figure 3 and Figure 4.With thin-walled, be welded into toroidal as wall thickness 1mm or 4 simmering and bending of thinner interior pipe, the caliber of thin walled tube is smaller than crest, and the bellows of diameter after the simmering and bending and desire shaping is suitable, the slim interior pipe assembly welding of simmering and bending is become the shape (abbreviation group pipe) of Fig. 2.During production, will organize pipe box, and again external mold 6 be closed merging the group pipe is embedded in the wave groove of external mold in internal mold 7 outsides.The plastic emitting that is equipped with extruder and injection machine on external mold is chewed, and the quantity of extruder depends on caliber (plastic squeeze amount).Injection machine mainly is to be used for the locked mode pressurize.Taking out inside and outside mould after injection moulding is finished respectively gets final product.
For injection plastic double-wall corrugated pipe directly easy to connect with pipe, can be in the injection moulding course of working at the bellows two ends integrated injection molding flange 2 respectively.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
