Abstract
본 발명은 상수도용으로 사용되는 경질 염화 비닐 재질의 내충격용 수도관(HI-VP)에 이탈 방지 장치를 내장한 일체형 편수 이음관에 관한 것이다. The present invention relates to a unitary single-piece fitting tube in which a separation prevention device is incorporated into a hard vinyl chloride-resistant water pipe (HI-VP) used for water supply.
종래의 HI-VP(경질염화 비닐관)편수 이음관의 삽입식 이음구조는 관의 한쪽선단을 편수 성형 후 패킹을 삽입하여 이에 상대측 연결파이프를 직렬 삽입방식으로 시공한 것으로, 이는 수밀성은 양호하나 고압(2㎏ f/㎤ 이상)시 연결관의 이탈방지력이 없어 상기 편수 이음관의 외부에 별도의 이탈방지장치를 장착하여야 하고, 곡관(elbow 류) 및 분기관(T형)과 같이 관로의 방향이 바뀌거나 나누어질 경우 별도의 이음관을 사용하므로 이는 고가의 주철제 이음관 사용과 시공기간의 연장, 시공비의 증가 등으로 비용증가의 결점이 있었다. The conventional HI-VP (rigid vinyl chloride pipe) single-piece joint structure is constructed by inserting a packing after inserting one end of the tube into a single-sided molding. (2kg f / cm3 or more) There is no separation prevention force of the connection pipe, so a separate separation prevention device should be installed on the outside of the single-handed joint pipe, and the elbow and branch pipe (T type) If the direction is changed or divided, a separate joint pipe is used, which results in an increase in cost due to the use of expensive cast iron joint pipes, the extension of the construction period, and the increase in the construction cost.
본 발명은 상기의 문제점을 해결하고자 안출한 것으로서, The present invention has been made to solve the above problems,
이의 발명요지는 HI-VP관의 기존편수이음관(편수 성형부 내부에 패킹을 장착함)의 바깥쪽에 연결관의 이탈을 방지하는 로크 링(Lock Ring)을 내장한 것인 바, 이는 상대측 연결관을 간단히 삽입하는 작업만으로 배관시공이 종료되는 것으로, 이는 상기의 직관뿐만 아니라 곡관(elbow관)과 분기관(T관)의 경우에도 공히 적용되고 합성수지제를 사용하므로서 매우 실용적이고 경제적인 특징이 있는 것이다. The present invention is a built-in lock ring to prevent the separation of the connector on the outer side of the existing one-piece fitting pipe (mounting the packing inside the one-piece molded part) of the HI-VP pipe, which is the other side The pipe construction is completed by simply inserting the wire, which is applied to the elbow pipe and the branch pipe (T pipe) as well as the straight pipe and has a very practical and economical feature by using a synthetic resin. will be.
Description
본 발명은 경질염화 비닐관(HI-VP관)으로 된 상수도용의 내충격용 수도관에 이탈방지장치를 내장한 일체형 편수 이음관에 관한 것이다. The present invention relates to a unitary single-piece joint pipe having a separation prevention device built in a water resistant impact pipe made of hard vinyl chloride pipe (HI-VP pipe).
종래의 경질 염화 비닐관(HI-VP관)의 삽입식 이음구조는 상기 수도관의 한쪽 선단부를 편수성형한 다음 이속에 패킹을 장입한 것으로, 이에 상대측 파이프를 직렬식 삽입방법으로 설치하는 것인바, 이는 수밀성은 매우 우수하나 2㎏ f/㎤ 이상의 고압발생시 연결관의 이탈방지력이 없으므로 상기 이음관의 외부에 별도의 이탈방지장치를 장착하여야 하고 곡관(elbow관) 및 분기관(T형관)과 같이 관로의 방향이 바뀌거나 나누어질 경우 별도의 이음관을 사용해야 할뿐만 아니라 주철제 이음관의 사용에 따른 시공기간의 연장 및 시공비 증가의 결점이 있었다. Conventional insert structure of rigid vinyl chloride pipe (HI-VP pipe) is a single-sided molded part of the water pipe and then the packing is loaded at this speed, and the other side pipe is installed by a serial insertion method, which is Watertightness is very good, but there is no separation prevention force of connecting pipe when high pressure of 2kg f / cm3 or more is generated, so separate separation prevention device should be installed on the outside of the joint pipe and like elbow pipe and branch pipe (T-shaped pipe) When the direction of the pipe is changed or divided, it is necessary to use a separate joint pipe, and there is a drawback of the extension of the construction period and the increase of construction cost due to the use of cast iron joint pipe.
본 발명은 상기의 문제점을 해결하고자 안출한 것으로서, The present invention has been made to solve the above problems,
이의 발명요지는 HI-VP관의 기존편수(편수성형부 내부에 패킹을 장착)의 바깥쪽에 로크링(Lock Ring)을 일체형으로 내장한 것으로, 이는 상기의 직관뿐만 아니라 엘보우 등의 곡관과 분기관(T관)에도 적용 가능할 뿐만 아니라 구조가 간단하고 설치가 간편한 특징이 있는 것이다. The present invention is to incorporate a lock ring integrally on the outer side of the existing number of HI-VP pipe (mounting the inside of the molding part), which is not only the straight pipe but also the elbow and the elbow and the branch pipe It is not only applicable to (T pipe) but also has a simple structure and easy installation.
이를 도면에 의거하여 상세하게 설명하면 다음과 같다. This will be described in detail with reference to the drawings as follows.
본 발명은 상수도용으로 사용하는 경질염화 비닐관(HI-VP관)의 일측단부를 다단으로 확관성형하되 내측의 걸림턱(5)보다 중간측의 패킹 삽입부(6)가 넓고 또한 상기 패킹삽입부(6)보다 외측의 로크링삽입부(7)를 다소 넓게 형성한 것으로, 상기 패킹 삽입부(6)에는 이음관 몸체(1)의 외경보다 다소 작고 겹층날개형상으로 형성된 패킹(2)을 일측방향으로 강제 삽입하여 밀착고정되게 한 다음 금속성 와이어 링(wire ring)형상의 오픈 링으로 내경을 정밀하게 스파이크(spike) 가공하여 형성한 로크링(Lock Ring)(3)을 삽입한 고강성 플라스틱 사출성형으로 내면부에 완만한 경사면(4a)을 형성한 로크링 케이스(Lock Ring Case)(4)를 상기한 로크링삽입부(7)에 장착한 일체형의 구조이다(도1 및 도2 참조). According to the present invention, one side end of the hard vinyl chloride pipe (HI-VP pipe) used for water supply is expanded in multiple stages, but the packing inserting portion 6 of the intermediate side is wider than the inner side of the locking jaw 5, and the packing inserting portion The outer ring lock insertion portion 7 is formed to be somewhat wider than the above, and the packing insertion portion 6 has a packing 2 formed in the shape of a layered wing that is somewhat smaller than the outer diameter of the joint pipe body 1. High rigidity plastic injection with a lock ring (3) formed by precisely spiked inner diameter with a metal wire ring-shaped open ring forcibly fixed by inserting in the direction. It is a unitary structure in which the lock ring case 4, in which the inclined surface 4a is formed in the inner surface part by molding, is attached to the lock ring insert 7 described above (see Figs. 1 and 2). .
그리고 부품 간소화를 위해 상기한 로크링 케이스(4)를 제거하고 몸체(1)의 경사면(1a)에 로크링(3)만을 삽입한 구조로 구성한 것으로 이는 고압시에 로크링(3)이 몸체(1)에 형성된 경사면(1a)을 따라 뒤로 밀리면서 밀착하게 되는 것이다(도3 및 도4 참조) In addition, the lock ring case 4 is removed to simplify the parts, and the lock ring 3 is inserted into the inclined surface 1a of the body 1. It is in close contact with each other while pushing backward along the inclined surface 1a formed in 1) (see FIGS. 3 and 4).
상기와 같이 구성된 본 발명의 실시예는 다음과 같다. Embodiments of the present invention configured as described above are as follows.
본 편수 이음관 몸체(1)에 연결관(8)을 연결 설치할 경우, 이음관 몸체(1)의 앞쪽에 장착된 로크링(3)이 로크링 케이스(4)의 경사면(4a)을 따라 내부로 밀리면서 확대되고 이와 함께 연결관(8)의 선단부가 계속하여 패킹(2)을 거쳐 상기 몸체(1)의 걸림턱(5)까지 삽입됨으로서 연결설치작업이 완료되는 것이며 특히 30㎏ f/㎠ 이내의 높은 수압이 발생할 경우, 상기 패킹(2)이 밀착하여 수밀되고 아울러 연결관(8)의 표면을 지지하는 로크 링(3)이 로크 링 케이스(4)의 경사면을 타고 약간뒤로 밀리는 과정에서 상기 로크링(3)은 연결관(8)의 중심방향으로 균일하게 압착함으로서 더욱 견고하게 연결관(8)을 지지하여 이탈을 방지하는 것이다.(도2, 도4 참조) In the case of connecting and installing the connecting pipe 8 to the single-piece fitting pipe body 1, the lock ring 3 mounted on the front of the fitting pipe body 1 is located along the inclined surface 4a of the locking ring case 4. It is enlarged while pushing and the connecting part 8 is continuously inserted through the packing 2 to the locking jaw 5 of the body 1, and thus the connection installation work is completed. In particular, 30 kg f / ㎠ In the event that high water pressure occurs within the packing 2, the packing 2 is tightly sealed and the lock ring 3 supporting the surface of the connecting pipe 8 is pushed back slightly on the inclined surface of the lock ring case 4. The locking ring 3 is pressed evenly in the center direction of the connecting pipe 8 to more firmly support the connecting pipe 8 to prevent the separation (see Figs. 2 and 4).
아울러 도5에서와 같이 곡관이나 T형의 분기관의 선단을 편수성형하여 이에 상기의 이탈방지장치를 장착한 이음관을 제조할 수도 있는 것이다. In addition, as shown in FIG. 5, the front end of the curved pipe or the T-shaped branch pipe may be molded in one piece to manufacture a joint pipe equipped with the above-described separation preventing device.
상기와 같이 본 발명은 경질염화비닐(HI-VP)수도관에 이탈방지장치를 내장한 일체형 편수 이음관에 관한 것으로 이는 패킹만을 장입한 종래의 HI-VP관에 비하여 수밀성과 연결관의 이탈방지력이 양호하고, 별도의 이탈방지장치가 불필요하며, 시공이 간편하여 기간을 단축할 수 있을 뿐만 아니라 엘보우 같은 곡관과 T 형의 분기관에도 적용할 수 있으므로 매우 실용적이고 경제적인 효과가 있는 것이다. As described above, the present invention relates to an integral single-piece joint pipe having a breakaway prevention device incorporated in a hard vinyl chloride (HI-VP) water pipe, which is watertight and preventive of the connection pipe compared to a conventional HI-VP pipe having only packing. This is good, there is no need for a separate departure prevention device, the construction is easy to shorten the period, as well as can be applied to elbows and elbows such as T-shaped branch pipe is very practical and economic effect.
