Description

소음방지관 { a noise reducing pipe }Noise reduction pipe {a noise reducing pipe}

본 발명은 유체의 이송과정에서 발생되는 소음을 방지할 수 있도록 한 소음방지관에 관한 것으로, 더 자세하게는 경질관의 내측과 외측에 각각 연질관을 일체로 형성한 것에 관한 것이다.The present invention relates to a noise preventing tube that can prevent noise generated in the transfer process of the fluid, and more particularly, to the soft tube is formed integrally on the inside and the outside of the hard tube.

일반적으로 하수관, 배수관 등의 유체이송관은 유체의 통과과정에서 소음이 유발되는데, 특히 고층 아파트에 설치되는 배수관의 경우 윗층에서 배출되는 물이 낙하하면서 배수관의 내벽과 충돌하게 되어 심한 소음이 발생하게 된다.In general, fluid transfer pipes such as sewage pipes and drainage pipes generate noise during the passage of fluids. In particular, in the case of a drainage pipe installed in a high-rise apartment, water discharged from the upper floor falls and collides with the inner wall of the drainage pipe, causing severe noise. .

이에 유체의 통과소음을 저감할 수 있도록 하는 많은 소음방지관이 제안된 바 있다.Accordingly, many noise prevention tubes have been proposed to reduce the noise passing through the fluid.

종래에 있어서 상기 소음방지관은 내측관과 외측관 사이에 공간부를 형성한 것이라든지 내측관과 외측관 사이에 발포심재를 설치한 것, 그리고 경질관의 내측에 연질관을 일체로 마련한 것 등이 주로 사용되고 있는 실정이다.In the related art, the noise prevention tube includes a space portion formed between the inner tube and the outer tube, a foam core material is installed between the inner tube and the outer tube, and a soft tube is integrally provided inside the hard tube. It is mainly used.

그러나 상기 종래의 소음방지관 중에서 내측관과 외측관 사이에 공간부를 형성한 것의 경우 내측관과 유체의 충돌로 의해 발생되는 충돌소음이 공간부에서 어느 정도 흡수 및 완화되는 효과가 있으나 공간부에서 진동이 발생하게 되어 결국 완벽한 소음흡수효과를 얻을 수 없게 되는 문제가 있었고, 나머지들의 것 역시 다소의 소음저감 효과를 기대할 수는 있지만 완벽한 소음차단이 어렵게 되는 문제가 있었다.However, in the case where the space portion is formed between the inner tube and the outer tube among the conventional noise suppression tubes, the impact noise generated by the collision of the inner tube and the fluid is absorbed and alleviated to some extent in the space portion, but the vibration in the space portion. This occurred, there was a problem that eventually can not get a perfect noise absorption effect, the rest of the problem can be expected a little noise reduction effect, but there was a problem that the perfect noise blocking is difficult.

본 발명은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 유체의 통과소음 및 진동을 저감 또는 방지할 수 있도록 하는 소음방지관을 제공하는 데에 있는 것이다.The present invention has been made in view of the above-described conventional situation, and an object thereof is to provide a noise preventing tube that can reduce or prevent passage noise and vibration of a fluid.

본 발명은 상기의 목적을 달성하기 위하여 경질관의 내측은 물론 외측에도 연질관을 형성하는 것을 특징으로 한다.The present invention is characterized in that in order to achieve the above object, the flexible tube is formed on the inside as well as the outside of the hard tube.

즉, 본 발명은 경질관의 내측에 제1연질관을 일체로 형성하고, 경질관의 외측에 제2연질관을 일체로 형성하여서 되는 것이다.That is, the present invention is formed by integrally forming the first soft tube inside the hard tube and integrally forming the second soft tube on the outside of the hard tube.

본 발명은 경질관의 내측에 제1연질관이 마련되고 경질관의 외측에 제2연질관이 마련되는 형태를 갖게 되는 것으로, 본 발명에 의하면 가장 안쪽인 제1연질관을 통과하는 유체의 충돌소음과 진동을 제1연질관에서 1차적으로 흡수하고, 경질관에서 2차적으로 흡수하며, 가장 바깥쪽인 제2연질관에서 최종적으로 흡수하여 소멸시킬 수 있게 되므로 소음저감효율을 극대화시킬 수 있게 되며, 내구성 및 내충격성, 그리고 상품성을 크게 향상시킬 수 있게 되는 등의 효과를 얻을 수 있게 된다.The present invention has a form in which the first soft tube is provided inside the hard tube and the second soft tube is provided outside the hard tube. According to the present invention, the collision of the fluid passing through the innermost first soft tube is performed. Noise and vibration can be absorbed primarily in the first soft tube, secondly in the hard tube, and finally absorbed and extinguished in the outermost second soft tube to maximize noise reduction efficiency. It is possible to obtain effects such as being able to greatly improve durability, impact resistance, and commercial property.

이하 본 발명의 구체적인 기술내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.Hereinafter, the specific technical details of the present invention will be described in more detail with reference to the accompanying drawings.

도 1에는 본 발명의 한 실시예의 사시도가 도시되어 있고, 도 2에는 동 실시예의 종단면도가 도시되어 있는 바, 본 발명의 소음방지관(10)은 경질관(11)의 내측에 제1연질관(12)을 일체로 형성하고, 경질관(11)의 외측에 제2연질관(13)을 일체로 형성하여서 되는 것이다.1 is a perspective view of one embodiment of the present invention, Figure 2 is a longitudinal cross-sectional view of the embodiment, bar noise prevention tube 10 of the present invention is the first soft inside the hard pipe (11) The pipe 12 is integrally formed, and the second soft pipe 13 is integrally formed on the outside of the hard pipe 11.

본 발명에 있어서 경질관(11)의 내측과 외측에 형성되는 제1연질관(12)과 제2연질관(13)은 고무나 합성수지 등의 소재로 형성될 수 있으며, 본 발명에서 그 재질은 특별히 한정되지 않지만 경질관(11)의 소재와 동일한 계열의 소재로 형성하는 것이 바람직하다.In the present invention, the first soft pipe 12 and the second soft pipe 13 formed on the inside and the outside of the hard pipe 11 may be formed of a material such as rubber or synthetic resin. Although it does not specifically limit, It is preferable to form with the raw material of the same series as the raw material of the hard pipe 11.

즉, 경질관(11)이 경질의 PVC인 경우 제1연질관(12)과 제2연질관(13)도 연질의 PVC로 형성하는 것이 좋으며, 이와 같이 경질관(11)과 각 연질관(12)(13)을 동일한 계열의 소재로 성형하게 되면, 그들을 압출성형하거나 사출성형할 때에 그들 상호간에 접착력이 향상되어 보다 견고하게 접착상태를 얻을 수 있게 된다.That is, when the hard pipe 11 is a hard PVC, the first soft pipe 12 and the second soft pipe 13 may also be formed of soft PVC. Thus, the hard pipe 11 and each soft pipe ( When 12) (13) is formed of the same series of materials, the adhesive force between them can be improved when they are extruded or injection molded, so that a more securely bonded state can be obtained.

상기와 같이 구성된 본 발명의 소음방지관은 고층건물의 배수관 등으로 사용할 수 있게 되는 것으로, 가장 안쪽인 제1연질관(12)에 낙하하는 폐수가 충돌하게 되는 경우 충돌소음 및 충격하중은 제1연질관(12)을 통해 1차적으로 흡수되고, 경질관(11)을 통해 2차적으로 흡수되며, 가장 바깥쪽인 제2연질관(13)을 통해 최종 흡수되어 완전하게 제거될 수 있게 된다.The noise prevention pipe of the present invention configured as described above is to be used as a drain pipe of a high-rise building, and when the wastewater falling on the innermost first soft pipe 12 collides with the impact noise and impact load, It is primarily absorbed through the soft tube 12, secondaryly absorbed through the hard tube 11, and finally absorbed through the outermost second soft tube 13 to be completely removed.

본 발명의 소음방지관은 제1연질관(12), 경질관(11), 제2연질관(13)의 3중구조로 형성되기 때문에 내구성 및 내충격성이 우수하게 되며, 겨울철에 동파를 방지할 수 있게 된다.Since the noise prevention tube of the present invention is formed in a triple structure of the first soft pipe 12, the hard pipe 11, and the second soft pipe 13, it has excellent durability and impact resistance, and prevents freezing in winter. It becomes possible.
