편수칼라관의 패킹 링 및 그 이음부 결합구조{Packing ring of one-way collar pipe and connection joint structure therefor}Packing ring of one-way collar pipe and connection joint structure therefor}

본 고안은 패킹 링에 관해, 보다 상세하게는 PVC 편수칼라관에 있어서 외관(암관)의 이음부(collar)의 내면에 패킹 링을 개재하여 내관(숫관)의 삽입저항을 극소화하고 소정의 수밀효과를 유지할 수 있도록 한 편수칼라관의 패킹 링 및 그 이음부 결합구조에 관한 것이다.The present invention relates to a packing ring, and more specifically, to a PVC single-collar color pipe, to minimize the insertion resistance of the inner pipe (male tube) through a packing ring on the inner surface of a collar of the outer appearance (female pipe) and to have a predetermined watertight effect. It relates to a packing ring and a joint structure of the one-piece collar tube to maintain the.

일반적으로, 편수칼라관(one-way collar pipe)은 일방향으로 흐르는 수도관에 사용되는 것으로, 그의 연결은 이음부 내부에 구비되는 패킹(수밀용) 링의 탄성과 내구성을 이용한 밀폐 및 이에 따른 수밀기능을 효과적으로 이용하도록 되어 있다.In general, a one-way collar pipe is used for a water pipe flowing in one direction, and the connection thereof is a seal using the elasticity and durability of the packing (watertight) ring provided inside the joint, and thus the watertight function. It is to use effectively.

도 1은 종래기술에 따른 편수칼라관의 이음부 결합구조의 일예로써, 외관(11)의 이음부(칼라부:12)는 단차형상으로 형성되고 그 안에는 통상적으로 탄성을 이용하기 위하여 고무재질로 형성된 패킹 링(13)이 개재되며, 상기 외관(11)의 이음부(12) 속으로 내관(14)이 삽입되면서 상기 패킹 링(13)이 점차적으로 압착 변형되어 이음부(12)의 내부공간을 메우는 것으로 되어 있다. 도2는 상기 패킹 링(13)의 형상을 예시한 것으로, 도2a와 같이 비절개된 형상이 통상적이지만, 도 2b와 같이 절개된 형상을 가질 수도 있다.1 is an example of the joint structure of the joint portion of the single-collar color tube according to the prior art, the joint portion (color portion: 12) of the appearance 11 is formed in a stepped shape and therein is usually made of rubber material in order to use elasticity The formed packing ring 13 is interposed, and the packing ring 13 is gradually compressed and deformed by inserting the inner tube 14 into the joint part 12 of the exterior 11, thereby forming an internal space of the joint part 12. It is supposed to fill. FIG. 2 illustrates the shape of the packing ring 13, and a non-cut shape is typical as shown in FIG. 2A, but may have a cut shape as shown in FIG. 2B.

그러나, 상기와 같은 구조의 패킹 링(13)은 다양한 형상의 변화에도 불구하고 통상적으로 고무재질로만 되어 있기 때문에 내관(14)의 삽입시 패킹 링(13)의 밀림현상이 일어나게 되어 소정의 수밀효과를 얻을 수 없었으며 또한 약한 체결력으로 인해 역수압작용시 패킹 링(13)의 파손이나 이탈되는 문제점이 발생하는 경우가 있었다.However, the packing ring 13 having the above structure is made of rubber material in spite of the change of various shapes, so that the sealing ring of the packing ring 13 occurs when the inner tube 14 is inserted. Also, due to the weak fastening force, there was a problem that breakage or separation of the packing ring 13 occurred during the reverse hydraulic action.

본 고안의 목적은 상기한 문제점을 해결하기 위해 안출된 것으로서, 패킹 링의 재질 및 형상을 각각의 기능에 따라 2종의 재질로 형성, 결합시켜 놓음으로써 강력한 수밀효과는 물론 역수압이 저지되어 파손 및 이탈이 방지되는 편수칼라관용 패킹 링을 제공하는 데 있다. The object of the present invention was devised to solve the above problems, and by forming and combining the material and shape of the packing ring with two kinds of materials according to their functions, a strong watertight effect as well as reverse water pressure is prevented and damaged. And it is to provide a packing ring for the single-colored color tube to prevent separation.

본 고안의 다른 목적은 상기한 패킹 링이 효과적으로 안착되는 편수칼라관의 이음부 결합구조를 제공하는 데 있다.Another object of the present invention is to provide a joint coupling structure of the single-collar tube that the packing ring is effectively seated.

상기 목적을 달성하기 위해, 본 고안에 따른 편수칼라관용 패킹 링은 삽입내측의 체결작용부분과 삽입외측의 수밀작용부분이 다른 재질로 제공되어 결합된 것을 특징으로 한다. In order to achieve the above object, the packing ring for single-necked color pipe according to the present invention is characterized in that the coupling action portion of the inner side and the water-tight action portion of the insertion outer side is provided by a different material combined.

본 고안의 바람직한 실시예에서, 상기 패킹 링의 체결작용부분은 친수성 고분자 화합물로서 단단한 재질인 PE(Polyethylene)재질 또는 플라스틱재질로 형성되고 상기 패킹 링의 수밀작용부분은 탄성이 풍부한 EPDM(Ethylene propylene rubber) 또는 엘라스토머(쇼어경도 50~70도 정도)로 형성된다.In a preferred embodiment of the present invention, the fastening action portion of the packing ring is formed of PE (Polyethylene) or plastic material of a rigid material as a hydrophilic polymer compound and the watertight action portion of the packing ring is EPDM (Ethylene propylene rubber) rich in elasticity ) Or an elastomer (Shore hardness of 50 to 70 degrees).

또한, 상기 편수칼라관의 이음부(칼라부)는 완만한 반원단면형상을 갖는다.In addition, the joint part (color part) of the said single-necked color tube has a moderate semicircular cross-sectional shape.

상기한 바와 같이 구성된 본 고안에 따른 편수칼라관의 패킹 링은 패킹 링이 삽입내측의 체결작용부분과 삽입외측의 수밀작용부분이 서로 제기능을 발휘하는 2종의 재질로 결합되어 구성되고 이음부가 반원단면형상으로 형성됨으로써, 소정의 수밀효과는 물론 강력한 체결력으로 인해 역수압을 저지시켜 패킹 링의 파손 및 이탈을 방지할 수 있고, 또한 편수칼라관의 높이를 낮출 수 있어 강도가 높다.The packing ring of the single-handed collar tube according to the present invention configured as described above is composed of two kinds of materials in which the packing ring is coupled to the fastening action portion inside the insertion portion and the watertight action portion outside the insertion portion. Since the semicircular cross-sectional shape is formed, it is possible to prevent the breakage and separation of the packing ring by preventing the reverse water pressure due to a predetermined watertight effect as well as a strong fastening force, and also to lower the height of the single color collar tube, thereby increasing the strength.

이하, 첨부도면을 참고로 하여 본 고안의 바람직한 실시예를 구체적으로 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 및 도 4는 본 고안에 따른 편수칼라관의 이음부 결합구조 및 패킹 링의 단면도를 보여 준다.3 and 4 show a cross-sectional view of the joint coupling structure and the packing ring of the single color collar tube according to the present invention.

도 3에 도시된 바와 같이, 본 고안에 따른 편수칼라관의 이음부 결합구조는 앞서의 도 1과 관련하여 설명한 바와 마찬가지로, 외관(21)의 이음부(22) 안에 패킹 링(23)이 개재되고, 상기 외관(21)의 이음부(22) 속으로 내관(24)이 삽입되면서 상기 패킹 링(23)이 점차적으로 압착 변형되어 이음부(22)의 내부공간을 메우는 것으로 되어 있다. As shown in FIG. 3, the joint coupling structure of the single-collar tube according to the present invention has a packing ring 23 interposed in the joint 22 of the exterior 21, as described with reference to FIG. 1. As the inner tube 24 is inserted into the joint 22 of the exterior 21, the packing ring 23 is gradually compressed and deformed to fill the internal space of the joint 22.

그러나, 본 고안에 따른 패킹 링(23)은 도 4에서 명료하게 이해할 수 있는 바와 같이, 종래의 단일 고무재질로만 형성된 패킹 링(13)과는 달리, 삽입내측의 체결작용부분(25)과 삽입외측의 수밀작용부분(26)이 각각의 필요기능에 따라 서로 다른 재질로 결합되어 있다는 중요한 특징을 갖고 있다. 그리고, 상기 외관(21)의 이음부(22)는 도 1에 도시된 종래기술의 외관 이음부(칼라부:12)의 단차형상과 달리 이음부의 깊이(높이)가 낮아지도록 반원단면형상으로 형성함으로써 편수칼라관 즉, 외관(21)의 강도가 높아질 수 있다.However, the packing ring 23 according to the present invention, as can be clearly understood in Fig. 4, unlike the conventional packing ring 13 formed only of a single rubber material, the inserting portion 25 and the insertion inner fastening portion 25 is inserted The outer watertight action portion 26 has an important feature that is coupled to different materials according to each required function. In addition, the joint part 22 of the exterior 21 is formed in a semi-circular cross-sectional shape so that the depth (height) of the joint is lowered, unlike the step shape of the exterior joint part (color part) 12 shown in FIG. 1. By doing so, the strength of the single-colored color tube, i.e., the appearance 21 can be increased.

본 고안의 바람직한 실시예에 의하면, 상기 패킹 링(23)의 체결작용부분(25)은 편수칼라관의 체결기능을 강화하기 위해 친수성 고분자 화합물로서 비교적 단단한 재질인 PE(Polyethylene)재질로 형성되고 상기 패킹 링(23)의 수밀작용부분(26)은 편수칼라관 본래의 수밀효과를 얻기 위해 종래기술에서 널리 사용되는 것으로 탄성이 풍부한 EPDM(Ethylene propylene rubber) 또는 엘라스토머(쇼어경도 50~70도 정도) 재질로 형성된다. 물론, 상기 패킹 링(23)의 체결작용부분(25)과 수밀작용부분(26)은 일반적인 접착제에 의한 평면 대 평면접착방식 또는 도 4에 도시된 바와 같이 접착제 제공없이 요철면 접착방식으로 결합될 수 있다. 도 5는 상기 패킹 링(23)의 실물사진을 보여준다.According to a preferred embodiment of the present invention, the fastening action portion 25 of the packing ring 23 is formed of a relatively hard material of PE (polyethylene) material as a hydrophilic polymer compound to enhance the fastening function of the single-colored color tube and the The watertight action portion 26 of the packing ring 23 is widely used in the prior art to obtain the original watertightness effect of the single color collar tube, and is rich in elastic EPDM (Ethylene propylene rubber) or elastomer (Shore hardness of about 50 to 70 degrees). It is made of material. Of course, the fastening action portion 25 and the watertight action portion 26 of the packing ring 23 can be combined in a plane-to-plane adhesion method by a general adhesive or by a concave-convex surface adhesion method without providing an adhesive as shown in FIG. 4. Can be. 5 shows a real picture of the packing ring 23.

상기한 바와 같이 구성된 편수칼라관의 결합구조는 패킹 링의 특수구성(이중 재질 결합구조)으로 인해 파이프의 삽입시 패킹 링의 밀림이 방지되고, 역수압에도 패킹 링의 이탈이 방지되며, 아울러 이음부의 반원단면형상으로 인해 깊이(높이)가 낮아지게 되어 편수칼라관의 강도가 높아진다.The coupling structure of the single-handed collar tube configured as described above prevents the packing ring from being pushed when the pipe is inserted due to the special configuration of the packing ring (double material coupling structure), and prevents the packing ring from being separated from the reverse water pressure. Due to the negative semi-circular cross-sectional shape, the depth (height) is lowered, which increases the strength of the single-colored color tube.

이상과 같이 본 고안을 도면에 도시한 실시예를 참고하여 설명하였으나, 이는 본 고안을 설명하기 위한 것일 뿐이며, 본 고안이 속하는 기술 분야의 통상의 식을 가진 자라면 고안의 상세한 설명으로부터 다양한 변형 또는 균등한 실시예가 가능하다는 것을 이해할 수 있을 것이다. 따라서 본 고안의 진정한 권리범위는 실용신안청구범위의 기술적 사상에 의해 결정되어야 할 것이다. Although the present invention has been described with reference to the embodiments shown in the drawings, this is only for explaining the present invention, and those having ordinary formulas in the technical field to which the present invention belongs, various modifications or It will be appreciated that equivalent embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical spirit of the utility model claims.
