Description

관 연결 조립체Pipe connection assembly
본 발명은 오,배수관 등 배관 시공상의 연결관을 연결하기 위한 관 연결 조립체에 관한 것이다. The present invention relates to a pipe connection assembly for connecting the connection pipe in the pipe construction, such as drain pipe.
일반적으로 관 연결 조립체는, 유체가 흐르는 관로 상에서 연결관과 연결관을 연결하여 수밀성을 유지하고, 이탈을 방지하는 수단으로 주로 사용된다. 관 연결 조립체는, 구조적 형태에 따라 직선형, 엘보형, T자형, 십자형 등 다양한 형태를 포함한다. 이러한 관 연결 조립체는 연결관들 상호 간의 수밀성과 결합성을 확보할 수 있어야 함은 물론, 진동과 충격에 쉽게 파손되거나 이탈되지 않을 것이 요구된다.In general, the pipe connection assembly is mainly used as a means for connecting the connecting pipe and the connecting pipe on the flow passage through which the fluid flows to maintain watertightness and prevent separation. The tube connection assembly may include various shapes such as straight, elbow, T-shaped, cross-shaped, etc., depending on the structural shape. Such pipe connection assemblies need to be able to secure the watertightness and bondability between the connectors, as well as not to be easily broken or broken by vibration and shock.
이와 같이, 연결관들을 연결하기 위한 관 연결 조립체에 관한 선행기술은, 등록특허 10-1523307(발명의 명칭 : 관 연결 조립체) 및 등록특허 10-1678379호(발명의 명칭 : 관 연결 조립장치)에 개시되어 있다.As such, the prior art related to the pipe connection assembly for connecting the connection pipes, Patent No. 10-1523307 (name of the invention: pipe connection assembly) and Patent No. 10-1678379 (name of the invention: pipe connection assembly device) Is disclosed.
상기 선행기술들에 개시되는 관 연결 조립체는, 배관을 연결하는 이음관을 고정시키기 위해, 수밀을 위한 탄성링과, 탄성링을 가압하기 위한 가압링을 일체화시켜 이음관 내부에 설치한다. The pipe connection assembly disclosed in the above prior art, in order to fix the joint pipe connecting the pipe, the elastic ring for the watertight and the pressure ring for pressing the elastic ring is integrally installed inside the joint pipe.
그리고, 상기 탄성링과 가압링의 외부에 클램프를 형성시켜 배관 시공시 별도의 분해작업 없이 연결될 관을 필요한 길이로 절단하여 이음관에 삽입시킬 수 있다. Then, by forming a clamp on the outside of the elastic ring and the pressure ring can be inserted into the pipe by cutting the pipe to be connected to the required length without any disassembly work when constructing the pipe.
이 상태에서 한 개의 볼트로 구성된 클램프를 현장에서 통상적으로 사용하는 전동 및 충전식 렌치를 사용할 수 있도록 한다. In this state, one-bolt clamps allow the use of electric and cordless wrenches commonly used in the field.
그 결과, 조립시 과도한 힘이 필요 없으며, 조임에 따라 연결될 관과 이음관을 간편하게 연결하여 고정시킬 수 있어서, 견고한 결속력과 수밀성이 확보되고, 시공 시간을 단축할 수 있는 장점이 있다. As a result, there is no need for excessive force when assembling, and can be easily connected and fixed by connecting the pipe and the joint pipe to be connected according to the tightening, ensuring a solid binding force and watertightness, there is an advantage that can shorten the construction time.
그러나, 이러한 선행기술은 다음과 같은 문제점을 안고 있다. However, this prior art has the following problems.
상세히, 연결될 관과 이음관을 연결하기 위해, 수밀을 위한 탄성링과, 탄성링을 가압하기 위한 가압링을 일체화시켜 이음관 내부에 설치하고, 이들을 외부에서 클램프가 감싸서 조임력을 발생시킨다. In detail, in order to connect the pipe and the joint pipe to be connected, an elastic ring for watertightness and a pressure ring for pressurizing the elastic ring are integrated and installed inside the joint pipe, and the clamps are wrapped around the outside to generate a tightening force.
여기서, 상기 클램프가, 3등분으로 분리되고, 두 지점에서 힌지 연결되기 때문에, 조립 공수가 추가되어 조립공정이 복잡한 단점이 있다. Here, since the clamp is divided into three parts and hinged at two points, the assembly process is added and the assembly process is complicated.
또한, 탄성링의 결합홈에, 가압링의 돌출 외주면과, 조임력 전달 빗면 및 조임력 전달 내주면이 결합되어, 가압링의 조임력 전달 내주면이 완전히 차단된다. 그 결과, 고무재질로 이루어진 탄성링의 가압 밀착면과 간격 유지면에, 연결될 관(P)의 외주면이 직접 밀착되어 간섭이 발생되어, 연결될 관의 삽입 및 분리 작업이 용이하지 않는 단점이 있다. In addition, the projecting outer circumferential surface of the pressing ring, the tightening force transmission inclined surface and the tightening force transmission inner circumferential surface is coupled to the coupling groove of the elastic ring, the tightening force transmission inner peripheral surface of the pressure ring is completely blocked. As a result, the outer circumferential surface of the pipe (P) to be connected is directly in close contact with the pressure contact surface and the space maintaining surface of the elastic ring made of a rubber material, the interference occurs, there is a disadvantage that the insertion and separation of the pipe to be connected is not easy.
뿐만 아니라, 일정 압력(1~2Kg/㎠)에는 견딜 수 있으나, 고압력(2Kg/㎠ 이상)에는 견디지 못하고 연결될 관이 이탈되는 문제점이 있다.In addition, it can withstand a certain pressure (1 ~ 2Kg / ㎠), but can not withstand high pressure (2Kg / ㎠ or more) there is a problem that the tube to be connected is separated.
그리고, 선행기술의 관 연결 조립장치는, 연결관을 삽입 및 결합시키기 위해, 수밀을 위한 탄성링과, 탄성링을 가압하기 위한 가압 밀착링을 일체화시켜 조인트관 양단의 확경부 내부에 안착시킨다. 그리고, 탄성링과 가입밀착링을 외부에서 감싸 조임력을 발생시키기 위해 세 개의 클램프부재를 사용함에 따라, 조립성이 떨어지고, 제조 원가가 상승하는 문제점이 있었다. And, the prior art pipe connection assembly device, in order to insert and couple the connection pipe, the elastic ring for the watertight and the pressure contact ring for pressing the elastic ring is integrated and seated inside the enlarged diameter portion of both ends of the joint pipe. In addition, as the three clamp members are used to wrap the elastic ring and the joining contact ring from the outside to generate a tightening force, there is a problem in that the assembly is inferior and the manufacturing cost is increased.
또한, 상기 다수의 클램프들의 테이퍼진 홈부에 스톱핀이 내측으로 돌출되게 체결 고정되어 연결관의 이탈이 방지되는 구조의 경우, 연결관의 외주면에 박히는 스톱핀의 고정력이 일정 압력(1~2Kg/㎠)에는 견딜 수 있으나, 고압력(2Kg/㎠ 이상)에는 견디지 못하고 연결관이 이탈되는 문제점이 있었다.In addition, in the case of the structure in which the stop pin is fastened to protrude inwardly to the tapered groove of the plurality of clamps to prevent the detachment of the connection pipe, the fixing force of the stop pin that is driven to the outer circumferential surface of the connection pipe is constant pressure (1 to 2 Kg / Cm 2), but can not withstand high pressure (2Kg / ㎠ or more), there was a problem that the connector is separated.
본 발명은 상기와 같은 문제점을 개선하기 위하여 제안된다. The present invention is proposed to improve the above problems.
