Abstract
The utility model relates to the technical field of pipeline connectors, in particular to a core layer foaming hush pipe which comprises an inner solid wall layer, an outer solid wall layer and a low-foaming core layer which is arranged between the inner solid wall layer and the outer solid wall layer; the diversion lines of a plurality of spiral bulges are arranged on the inner wall of the inner solid wall layer; and the spiral angles of the diversion lines are 75 degrees. According to the core layer foaming hush pipe, the noise reduction and sound isolation performance of the core layer foaming pipe in the prior art is further improved.
Description
Technical field
The utility model relates to the pipe coupling technical field, particularly relates to a kind of core layer foam silencing pipe.
Background technique
At present, used in construction drainage Vybak pipe, generally all by a kind of inside and outside two-layer identical with the ordinary rigid polyvinyl chloride pipe, the centre is a kind of novel tube of low foaming layer, and be provided with a helical raised channelizing line in the inwall, itself is except corrosion-resistant, light weight, insulation, outside shockproof, its hoop rigidity also exceeds about 8 times of the ordinary rigid polyvinyl chloride pipe, but compares conservation more than 25% with the solid wall pipe material, and has a decrease of noise functions, this product is in draining, and carrying needs to be used widely in the heat insulation liquid pipeline, along with the degree of progress speed of China to the protection house, drainage pipe use amount cumulative year after year has become the kind of consumption figure maximum in the various plastic pipes.
Yet, existing core layer foam silencing pipe, structural design is not able to preferably so that the fluid attached jet turns, and avoids and the effect of air impact with further noise reduction.
The model utility content
The purpose of this utility model is to solve prior art center core layer foaming hush pipe, and the noise reduction soundproof effect is not good problem.
For achieving the above object, the utility model provides a kind of core layer foam silencing pipe, comprise: interior real parietal layer and outer real parietal layer, and the low foamed core layer between described inside and outside real parietal layer, the inwall of described interior real parietal layer is provided with the channelizing line of many spiral salients, and the helix angle of described channelizing line is 75 degree.
Alternatively, described channelizing line is set to 10 to 20, and the muscle height is 4.0mm.
Alternatively, described inside and outside real parietal layer is Corvic, and the relative density of described low foamed core layer is 0.7 to 0.9.
A kind of core layer foam silencing pipe that the utility model provides has further improved the noise reduction sound insulation value of prior art center core layer foaming tube.
Description of drawings
The structural representation of the core layer foam silencing pipe that provides among the utility model embodiment is provided Fig. 1.
Embodiment
Below by specific instantiation mode of execution of the present utility model is described, those skilled in the art can understand other advantages of the present utility model and effect easily by the disclosed content of this specification.The utility model can also be implemented or be used by other different embodiment, and the every details in this specification also can be based on different viewpoints and application, carries out various modifications or change under the spirit of the present utility model not deviating from.
Need to prove, the appended graphic structure that illustrates of this specification, ratio, size etc., equal contents in order to cooperate specification to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
Please in conjunction with shown in Figure 1, structural representation of a kind of core layer foam silencing pipe of providing in the present embodiment is provided for it, this core layer foam silencing pipe, comprise: interior real parietal layer 1 and outer real parietal layer 3, and the low foamed core layer 2 between described inside and outside real parietal layer 1,3, the inwall of described interior real parietal layer 1 is provided with the channelizing line 4 of many spiral salients, and the helix angle of described channelizing line 4 is 75 degree.
Owing to structurally having utilized worker's type structural principle in the mechanics of materials, and having had the good low foamed core layer 2 of energy-absorbing defening effect, rationally the spiral salient channelizing line 4 of angle is arranged so that this foaming hush pipe further promotes noise reduction capability in addition.
Preferably, described channelizing line 4 is set to 10 to 20, the high 4.0mm that is set to of muscle.
General, described inside and outside real parietal layer 1,3 be the Corvic material, and the relative density of described low foamed core layer 2 is 0.7 to 0.9, compares with the ordinary rigid polyvinyl chloride pipe, has the advantages such as light weight, sound insulation, insulation, shockproof and raising serviceability temperature.
Produce two antidromous cone double screw extruders of the general employing of foaming hush pipe, this two extruders is the inside and outside real parietal layer 1,3 and low foamed core layer 2 of extruding pipe material respectively, because hanging down foamed core layer 2 materials amounts greater than inside and outside real parietal layer 1,3, the extruder model of extruding low foamed core layer 2 should be greater than inside and outside real parietal layer 1,3 extruder models, after real parietal layer 1,3 reaches low foamed core layer 2 inside and outside extruding, use the co-extruding mould compound molding, again through the vacuum cooling sizing, rear spraying cooling, then lettering, again by pipe tractor traction and the cutting of cast-cutting saw scale etc.
A kind of core layer foam silencing pipe that the utility model provides has further improved the noise reduction sound insulation value of prior art center core layer foaming tube.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not is used for restriction the utility model.Any person skilled in the art scholar all can be under spirit of the present utility model and category, and above-described embodiment is modified or changed.Therefore, have in the technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of finishing under spirit that the utility model discloses and the technological thought, must be contained by claim of the present utility model.
