Abstract
The utility model relates to building downpipes and discloses a weather-proof anti-aging downpipe. The downpipe (1) is a PVC (polyvinyl chloride) pipe; the outer surface of the downpipe (1) is provided with an ASA (Acrylonitrile Styrene Acrylate copolymer) resin layer (2); the thickness of the ASA resin layer (2) is within 0.2 to 0.4 mm. According to the weather-proof anti-aging downpipe, the outer surface of the downpipe is provided with the ASA resin layer which is used for protecting the downpipe and accordingly the degradation, aging, fading caused by ultraviolet radiation can be resisted, the decomposition or discoloration caused by the high temperature in the atmospheric oxidation machining process can be prevented due to the downpipe, and the anti-aging and weather-proof performance of the downpipe can be improved; the empty chamber is formed in a wall body of the downpipe and accordingly the leak of the water noise can be reduced in a certain extent and mute cotton is arranged in the empty chamber to enhance the effect; the wall body of the downpipe can be protected in a certain extent due to supporting ribs and accordingly the wall body of the downpipe is not easy to fracture; the blocking of the downpipe can be prevented due to a threaded spring.
Description
Technical field
The utility model relates to leader for building, has related in particular to a kind of weather-proof, aging-resistant leader.
Background technology
Leader of the prior art is after installing, exposed under the sun, it is because being exposed to the sun for a long time, easily oxidized, separate out pigment and produce and fade and very easily aging, be exposed to the sun for a long time and also can cause leader to break, at this moment just need to change leader, but because leader is mounted in house sidings, this causes when dismounting leader very inconvenient; And existing leader is when rainy day, and rainwater falls from eminence, can produce larger noise, affect people's life; And the leader of washing in family at present below nappy and wash basin often easily stops up, its reason is that earth, hair, swill are easily deposited collection in pipeline, be attached on tube wall, although most, wash in nappy and wash basin and be all provided with filter or the screen pack that filters large impurity, still can not thoroughly deal with problems; Once leader will just can dredge with special-purpose instrument, and leader also can often there will be the situation of obstruction after stopping up.
Summary of the invention
The utility model for leader in prior art easily fade, aging, break, during use, produce larger noise, the shortcoming of easily blocking in pipe, provides a kind of weather-proof, aging-resistant leader that reduces noise, anti-blocking.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Weather-proof, aging-resistant leader, leader is pvc pipe, and leader external surface is provided with ASA resin bed, and the thickness of ASA resin bed is at 0.2～0.4mm, and the thickness of leader is at 1.3～1.7mm.
As preferably, in the wall body of leader, offer cavity.Cavity can reduce leaking of waterfall noise in certain degree.
As preferably, in cavity, be provided with silencing cotton.In cavity, be provided with silencing cotton and can strengthen its effect.
As preferably, in cavity, be evenly provided with brace rod.Brace rod plays certain protective effect to the wall body of leader, makes the wall body of leader be difficult for breaking.
As preferably, in the wall body of leader, enclose and be equipped with thread groove, in thread groove, be provided with screw thread spring.
ASA is formed by rubber copolymerized the closing of styrene, acrylonitrile and acryl.
The utility model arranges ASA resin bed at leader external surface, for the protection of leader, can resist because of ultraviolet ray irradiate caused degraded, aging, fade, ASA resin bed can prevent that leader from, because of decomposition or variable color that the high temperature in the oxidation process in atmosphere causes, can improve the anti-aging and weather resistance of leader; In the wall body of leader, offer cavity, cavity can reduce leaking of waterfall noise in certain degree, is provided with silencing cotton and can strengthens its effect in cavity; Brace rod plays certain protective effect to the wall body of leader, makes the wall body of leader be difficult for breaking; Spiral thread groove and screw thread spring form helical form refluence groove at the inwall of body, have improved the scouring force of current, can prevent that residue from adhering at tube wall; In addition, once formation is stopped up, can also remove the residue being attached on tube wall by rotation screw thread spring, or directly screw thread spring be taken out, remove the residue adhering to, and without using special tool to get final product the pipeline of dredge blockage.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Weather-proof, aging-resistant leader, as shown in Figure 1 to Figure 2, leader 1 is pvc pipe, leader 1 external surface is provided with ASA resin bed 2.
The thickness of ASA resin bed 2 is at 0.2～0.4mm.The thickness of leader 1 is at 1.3～1.7mm.In the present embodiment, the thickness of ASA resin bed 2 is 0.3mm, and the thickness of leader 1 is 1.4mm.
As shown in Figure 3, its structure is substantially the same manner as Example 1, and difference is to offer in the wall body of leader 1 cavity 3 of sealing.In cavity 3, be provided with silencing cotton.
As shown in Figure 4, its structure is substantially the same manner as Example 2, and difference is the interior brace rod 4 that is evenly provided with of cavity 3.
Embodiment 4
As shown in Figure 5, its structure is substantially the same manner as Example 1, and difference is to enclose and be equipped with spiral thread groove in the wall body of leader 11, is provided with screw thread spring 5 in thread groove.Leader 1 can be cylinder.
As shown in Figure 6, its structure is substantially the same manner as Example 1, and difference is to offer in the wall body of leader 1 cavity 3 of sealing.In cavity 3, be provided with silencing cotton.In the wall body of leader 1, enclose and be equipped with thread groove, in thread groove, be provided with screw thread spring 5.Leader 1 can be cylinder.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
