Description

소음방지용 이음관{A joint pipe for prevention of noise}A joint pipe for prevention of noise

본 발명은 배관연결시 사용되는 소음방지용 이음관에 관한 것으로, 더욱 상세하게는 이음관본체의 내측에 제 1공간부를 형성시키는 제 1연질흡음관이 삽입설치되는 동시에 제 1연질흡음관의 내측에 제 2공간부를 형성시키는 제 2연질흡음관이 삽입설치되도록 구성되거나, 또한 상기 구성에 부가되어 제 2연질흡음관의 표면에 돌기홈이 형성되거나, 제 2연질흡음관의 배출단부에 지지살이 구비된 연장관이 형성되거나, 이음관본체의 외측에 공간부를 형성시키는 한 조로 된 분할커버가 결합설치되거나, 분할커버에 의해 형성된 공간부에 폴리우레탄층이 충전되도록 구성되므로써, 소음방지성능을 대폭 향상시켜 이음관의 외부로 유출되는 소음을 최소화할 수 있도록 하는 소음방지용 이음관에 관한 것이다.The present invention relates to a noise preventing joint pipe used when connecting a pipe, and more particularly, a first soft sound absorbing tube for forming a first space portion inside the joint pipe body is inserted and installed inside the first soft sound absorbing tube. The second soft sound absorbing tube for forming the second space portion is configured to be inserted, or in addition to the configuration, the projection groove is formed on the surface of the second soft sound absorbing tube, or the support is provided on the discharge end of the second soft sound absorbing tube The expansion tube is formed, or a pair of split covers for forming a space portion on the outer side of the joint pipe body are combined or installed, or the polyurethane layer is filled in the space formed by the split cover, thereby greatly improving the noise prevention performance. The present invention relates to a noise preventing joint pipe that can minimize noise flowing out of the joint pipe.

일반적으로 배관연결시 사용되는 이음관, 예를 들어 유체의 방향을 직각으로 변경시키기 위하여 사용하는 엘보우형 이음관의 경우에는 특히 유입배관을 거쳐 이음관내부로 유입되는 유체가 이음관의 굴곡형상에 따른 급격한 방향전환으로 인하여 이음관본체의 내벽에 강하게 부딪히게 되면서 시끄러운 마찰소음을 발생시키게 된다.In general, in the case of the elbow type joint pipe used to connect the pipe at a right angle, for example, the fluid flowing into the joint pipe through the inlet pipe is formed according to the bending shape of the pipe. Due to the rapid change of direction, the inner wall of the joint pipe body is strongly hit and generates loud friction noise.

종래에는 이음관내에서 발생되는 이러한 유체소음을 저감시키기 위하여 입출구의 단부에 배관체결부재가 나사결합되는 이음관본체의 내측에 연질PVC나 연질고무 또는 실리콘재질로 된 연질흡음관이 삽입설치되어 이음관본체의 내측면과 연질흡음관의 외측면사이에 공간부를 형성시키도록 구성되어 있는 소음방지용 이음관이 널리 사용되고 있었다.Conventionally, in order to reduce such fluid noise generated in a joint pipe, a soft PVC, soft rubber, or a soft sound absorbing tube made of silicone is inserted into the joint pipe body in which the pipe fastening member is screwed to the end of the inlet and outlet. Noise preventing fittings configured to form a space between the inner side of the main body and the outer side of the soft sound absorbing tube have been widely used.

이와 같은 종래의 소음방지용 이음관을 구성하는 이음관본체에 나사결합되는 배관체결부재로서는 조임캡이나 어댑터 등이 있는데, 상기 조임캡은 일반적인 PVC파이프의 배관연결시 이음관본체의 유입단부와 배출단부의 외주연에 패킹을 개재하여 각각 나사결합되므로써 PVC파이프와 이음관본체를 연결시킬 경우에 주로 사용되며, 상기 어댑터는 하부가 양변기용 배관연결시 이음관본체의 유입단부 내주연에 나사결합되고 상부가 양변기의 하단에 매설된 슬리이브의 내측에 끼움결합되므로써 슬리이브와 이음관본체를 연결시킬 경우에 주로 사용된다.The pipe fastening member which is screwed to the joint pipe main body constituting the conventional noise preventing joint pipe includes a tightening cap or an adapter, and the tightening cap has an inlet end and an outlet end of the joint pipe main body when connecting a pipe of a general PVC pipe. It is mainly used to connect the PVC pipe and the joint pipe main body by screwing each other through the packing on the outer circumference of the joint. The adapter is screwed to the inner circumference of the inlet end of the joint pipe main body when the lower part is connected to the toilet. This is mainly used to connect the sleeve and the joint body by fitting the inside of the sleeve buried at the bottom of the toilet.

상기와 같이 구성되어 있는 종래의 소음방지용 이음관은 유입배관을 거쳐 이음관내부로 유입되는 유체가 이음관의 굴곡형상에 따른 급격한 방향전환시 이음관본체의 내벽에 부딪히면서 가하게 되는 충격력이 이음관본체의 내측에 삽입설치된 연질흡음관의 자체탄성과 이음관본체의 내측면과 연질흡음관의 외측면사이에 형성되는 공간부에 의해 흡수되어 차단되도록 하므로써 이음관내에서 발생되는 소음을 저감시키게 된다.In the conventional noise preventing joint pipe configured as described above, the impact force applied while hitting the inner wall of the joint pipe main body when the fluid flowing into the joint pipe through the inlet pipe suddenly changes according to the curved shape of the joint pipe is applied to the joint pipe main body. The noise generated in the joint pipe can be reduced by being absorbed and blocked by a space formed between the self-elasticity of the flexible sound absorbing tube installed inside and the inner side of the joint body and the outer side of the flexible sound absorbing tube.

그러나, 상기와 같은 종래의 소음방지용 이음관은 이음관본체의 내측에 삽입설치된 연질흡음관과 연질흡음관에 의해 형성되는 공간부에 의해 이음관내부의 유체소음을 어느 정도 저감시킬 수 있는 효과는 있었지만, 고층건물이나 아파트와 같은 복층건물의 층간소음 및 각종 배수소음, 특히 양변기의 배수소음의 최소화가 쾌적한 주거환경을 결정짓는 중요한 요인으로 부각되고 있는 최근의 건축환경을 충족시키기에는 여전히 미흡한 실정이었다.However, the conventional noise-proof joint pipe as described above has an effect of reducing the noise of the fluid inside the joint pipe to some extent by the space portion formed by the soft sound absorbing tube and the soft sound absorbing tube installed inside the joint pipe body. In addition, the minimization of floor noise and various drainage noises in multi-story buildings such as high-rise buildings and apartments, in particular, the minimization of drainage noise in toilets, is still insufficient to meet the recent construction environment, which is an important factor in determining a pleasant living environment.

따라서, 최근의 건축환경에서 특히 최우선적으로 고려되고 있는 각종 배수소음, 특히 양변기의 배수소음 등을 가능한 한 최소화할 수 있는 소음방지용 이음관의 개발이 절실히 요구되고 있었다.Therefore, there is an urgent need for the development of noise preventing fitting tubes that can minimize various kinds of drainage noise, especially drainage noise of toilet bowls, which are considered as the top priority in recent construction environments.

It is configured to be installed, or in addition to the configuration is formed with a projection groove on the surface of the second soft sound absorbing tube, an extension pipe provided with a support bar at the discharge end of the second soft sound absorbing tube, or the outside of the joint pipe body The split cover is formed to be coupled to a pair of partitions to form a space portion, or the polyurethane layer is filled into the space formed by the partition cover, thereby greatly improving the noise prevention performance to minimize the noise flowing out of the joint pipe.
