It is made of ash and inserts and installs a noise attenuating tube that protrudes a plurality of supports on the inner and outer surfaces to easily manufacture the triple joint pipe with excellent noise attenuation effect and to reduce the manufacturing cost. In order to improve the sealing force in the portion connected to the drain pipe is securely connected to the drain pipe connection by installing a double double packing packing integrally.

종래의 소음방지용 삼중이음관은 특허등록 제502944호(발명의 명칭 : 소음방지 삼중 이음관의 제조방법 및 그 이음관)로 알려져 있으며, 이러한 종래의 발명은 그 청구범위에 기재된 바와 같이 청구항 1항에는 소음방지 삼중이음관의 제조방법을 기재하고 있고, 청구항 2항에는 소음방지 삼중 이음관을 기재하고 있다.Conventional noise prevention triple joint pipe is known as Patent Registration No. 502944 (name of the invention: a method of manufacturing a noise resistant triple joint pipe and its joint pipe), and this conventional invention is claimed in claim 1 as described in the claims. Describes a method for manufacturing a noise-proof triple joint, and claim 2 describes a noise-proof triple joint.

먼저, 청구항 1항의 소음방지 삼중이음관의 제조방법은, 내측관을 성형하는 1차 사출공정 단계와, 상기 1차 사출공정에 의해 사출된 내측관의 외면에는 미세한 기공을 형성하는 발포층을 성형하는 2차 사출공정 단계와, 상기 1차 및 2차 사출공정에 의해 성형된 내측관과 발포층의 외면에 외측관을 성형하는 3차 사출공정 단계로 이루어지는 것이다.First, the method for manufacturing a noise-proof triple joint tube of claim 1, the first injection process step of forming the inner tube, and the outer surface of the inner tube injected by the first injection process, forming a foam layer to form fine pores And a third injection process step of forming an outer tube on the outer surface of the inner tube and the foam layer formed by the first and second injection processes.

청구항 2항에 기재된 소음방지 삼중 이음관은, 관의 단부에 턱을 형성하고, 턱의 외측에 플렌지를 형성하며, 플렌지의 외측에 나사 형태의 체결부를 형성하고, 관의 단부 내측에는 통상의 패킹을 삽입할 수 있도록 자리 홈을 일체로 형성하는 경질의 수지로 내측관과, 상기 내측관의 외면에는 성형하되, 턱까지 미세한 기공을 형성한 발포층 및 상기 내측관과 발포층의 외면에 성형하되, 내측관의 플렌지까지 경질의 수지로 성형한 외측관으로 구성하는 것이다.The anti-noise triple joint pipe according to claim 2 has a jaw formed at the end of the tube, a flange formed at the outside of the jaw, a screw-shaped fastening portion formed at the outside of the flange, and a normal packing inside the end of the tube. Molded on the inner tube and the outer surface of the inner tube with a hard resin to form a seat groove integrally so that the insert can be inserted into the foam layer and the outer surface of the inner tube and the foam layer formed fine pores to the jaw, The outer tube is formed by hard resin up to the flange of the inner tube.

이와 같은 종래의 발명은 내측관과 외측관, 그리고 발포층이 각각 별도로 이루어지고, 1차로 내측관을 사출성형한 뒤에 이것의 외측에 발포층을 2차로 성형하며, 내측관의 외부에 발포층이 성형된 것의 외측에 외측관을 3차로 사출 성형하는 것이므로 아래와 같은 문제점이 대두되었다.In the conventional invention, the inner tube, the outer tube, and the foam layer are separately formed, and the inner tube is first injection-molded, and then the foam layer is secondly molded on the outside thereof, and the foam layer is formed outside the inner tube. Since the injection molding of the outer tube on the outside of the molded third, the following problems have arisen.

즉 종래의 문제점은 첫째 내측관과, 발포층, 외측관을 별도로 사출성형하므로 3개의 금형이 필요하여 제조원가를 상승시키는 문제와, 이미 1차로 성형된 내측관을 사출기에 투입시킨 상태로 내측관의 외부에 발포층을 2차로 성형하고, 2차로 사출성형한 반제품을 또 다시 사출기에 투입시킨 상태로 외측관을 3차로 사출성형하므로 작업이 매우 어려움과 동시에 불량이 많이 발생하는 문제와, 단계별로 작업된 다량의 반제품을 보관하는데 많은 공간을 차지하는 공간적인 문제점까지 지니고 있었다. In other words, the conventional problem is that the first inner tube, the foam layer, and the outer tube are separately injection molded, so three molds are required to increase the manufacturing cost, and the inner tube of the inner tube is first put into the injection machine. Secondly, the foam layer is molded on the outside, and the semi-finished product is injected into the injection molding machine again. There was even a spatial problem that takes up a lot of space for storing large quantities of semi-finished products.

The noise generated when the water passes by the triple wall made of attenuating pipe 10 is attenuated. In the present invention, the noise attenuating pipe 10 is formed in a soft state, and the noise attenuating pipe 10 is attenuated. As the plurality of support teeth 9 are formed on the inner and outer circumferential surfaces of the body 8, between the outer circumferential surface of the attenuation tube body 8 and the inner circumferential surface of the outer tube portion 2 between the adjacent support ribs 9, A sound absorbing space 11 is formed between the inner circumferential surface of the attenuating tube body 8 and the outer circumferential surface of the inner pipe portion 1 between the adjacent support ribs 9, so that the noise attenuation effect due to each of the sound absorbing space portions 11 is reduced. It will be improved further.

그리고, 상기 소음감쇄관(10)은 연질합성수지를 발포시켜 다수의 기공이 형성되게 성형하는 것이 바람직함을 밝혀둔다.In addition, the noise reduction tube 10 is foamed with a soft synthetic resin it is found that it is preferable to mold to form a plurality of pores.

상기와 같이 본 발명의 소음방지용 삼중이음관은, 내외측관부가 일체로 형성된 이음관본체와, 내외측관부의 사이에 형성되는 삽입공간부로 삽입되는 소음감쇄관을 별도로 성형한 뒤에, 이음관본체의 삽입공간부로 연질의 소음감쇄관을 삽입시킬 수 있게 하여 불량의 발생소지를 제거함과 동시에 제조원가를 대폭 절감시킬 수 있는 효과가 있으며, 배수관이 연결되는 배수관연결부에는 2개의 날개살을 일체로 형성한 패킹을 이중으로 설치하여 배수관이 배수관연결부에 든든하게 연결됨과 동시에, 배수관이 연결된 부분에서의 밀봉력이 향상될 수 있는 효과가 있는 것이다.As described above, the triple joint pipe for noise prevention according to the present invention is formed by separately forming a joint pipe body in which the inner and outer pipe parts are integrally formed, and a noise attenuating pipe inserted into the insertion space formed between the inner and outer pipe parts. Soft noise attenuation tube can be inserted into the insertion space of the product, which eliminates the occurrence of defects and at the same time significantly reduces the manufacturing cost. By installing the packing in duplicate, the drain pipe is firmly connected to the drain pipe connection part, and at the same time, the sealing force at the part to which the drain pipe is connected is improved.
