Description

폴리프로필렌 랜덤 공중합체(ＰＰＲ)또는 폴리부틸렌(ＰＢ)을 원료로 하는 보일러 중계관{BOILER JUNCTION TUBE MADE FROM POLYPROPYLENE RANDOM COPOLYMER AND POLYBUTYLENE}BOILER JUNCTION TUBE MADE FROM POLYPROPYLENE RANDOM COPOLYMER AND POLYBUTYLENE}

본 발명은 공지의 열가소성 합성수지 소재인 폴리플로필렌 랜덤 공중합체(Polypropylene Random coplymer)(PPR) 또는 폴리부틸렌(polybutylene)(PB)을 원료로 하여 성형되는 보일러 중계관에 관한 것으로 보다 구체적인 것은 중계관 본체에 형성되는 연결구에 온수주입용호스와 분배용호스를 직접 접속할 수 있게 금속제호스 연결관을 접속부가 돌출되게 매설하고 중계관 본체에 보온재와 보강철판을 견고하게 부착시킬 수 있도록 연결구에 수나사부를 형성하여 체결너트를 나사조립할 수 있게 함으로써 사용이 편리하도록 만든 것이다.The present invention relates to a boiler relay tube which is formed by using polypropylene random coplymer (PPR) or polybutylene (PB) which is a known thermoplastic synthetic resin material. The metal hose connector is embedded to connect the hot water injection hose and the distribution hose directly to the connector formed in the main body, and the male thread is formed in the connector so that the insulation and the reinforcing steel plate can be firmly attached to the relay main body. The fastening nut is screwed to make it easier to use.

폴리프로필렌 랜덤 공중합체 또는 폴리부틸렌을 소재로 하는 보일러 중계관은 파이프로 된 본체 양단에 마개를 끼워 접합하고 본체 주벽을 따라 일정간격에 4~7개의 구멍을 뚫어서 온수주입호스와 분배호스를 접속할 수 있게 파이프 본체와 같은 소재로 연결구를 형성하여 용접하고 각 연결구에 암나사를 형성하여 온수주입호스와 분배호스 끝에 결합시킨 금속제 연결관의 수나사부를 나사조립하여 배관을 형성하도록 구성하고 있다.Boiler relay pipes made of polypropylene random copolymer or polybutylene are joined by plugs at both ends of the main body of pipes, and 4 ~ 7 holes are drilled at regular intervals along the main wall to connect the hot water injection hose and the distribution hose. The connector is formed to be welded by the same material as the main body of the pipe, and the female thread is formed on each connector to assemble the male threaded portion of the metal connecting pipe coupled to the hot water injection hose and the distribution hose to form a pipe.

따라서 중계관에 부착된 연결구의 암나사공에 금속제연결관의 수나사를 나사 조립하고 금속제연결관 외측에 다시 호스 접속부를 만들어 호스를 체결해야 하므로 체결해야 할 곳이 많아 조립이 번거롭고 각 체결부는 나사부가 형성되어 조립하면 나사 홈부를 통해 누수가 발생할 수 있는바 이를 막기 위해 나사산 입구에 실링용 끈을 감아서 나사조립을 실시해야 하므로 고도의 숙련된 기술을 요할 뿐 아니라 나사가 조립된 이후에도 정밀성과 내구성이 담보되지 못해 시공후에 누출이 발생하여 보수를 해야 하는 문제가 일어나고 이로인해 부가 비용이 발생하는 어려움이 있으며 중계관 본체외면에 보온재를 피복하고 보강철판을 씌움에 있어서도 보일러 중계관의 연결구에 나사결합되는 연결관을 이용하여 부착되게 하였으므로 연결관에 이완요인이 발생하는 등의 문제점이 있었다.Therefore, it is necessary to screw the male screw of the metal connector pipe to the female threaded hole of the connector attached to the relay pipe and make the hose connection part again on the outer side of the metal connector pipe to fasten the hose. When assembled, screw sealing should be done by winding sealing strings at the threaded inlet to prevent leakage through screw grooves. This requires not only highly skilled skills but also guarantees precision and durability even after the screws are assembled. The leak occurs after construction, which requires repairs, and there is a problem in that additional costs are incurred, and the connection that is screwed to the connector of the boiler relay pipe also covers the insulation on the outer surface of the relay pipe and covers the reinforcing steel plate. Because it is attached using a pipe, the relaxation factor There was a problem such as occurring.

본 발명은 보일러 중계관의 연결구에 온수주입용 호스나 분배용 호스를 접속할 때 접속 작업이 편리하고 중계관 외면에 보온제를 피복하여 보강철판을 부착하는 작업이 용이한 온수중계관을 얻고자 함에 있다.The present invention is to obtain a hot water relay tube when the connection of the hot water injection hose or distribution hose to the connector of the boiler relay is convenient and easy to attach the reinforcing iron plate by coating the insulation on the outer surface of the relay tube have.

본 발명은 보일러 중계관에 형성되는 연결구에 호스접속부가 형성된 금속제호스연결관(4)를 일체로 매설하고 연결구 외면에 수나사부를 형성하여 체결너트(6)를 나사조립할 수 있게 구성하여 호스의 접속은 물론이고 보온재와 보강철판의 조립까지 편리한 제품이 되게 한 것이다.The present invention is integrally embedded with a metal hose connecting pipe (4) formed with a hose connection to the connector formed in the boiler relay pipe and the male nut is formed on the outer surface of the connector to configure the fastening nut (6) by screwing the connection of the hose Of course, it would be a convenient product to assemble the insulation and reinforcing steel sheet.

이와 같이 된 본 발명은 온수중계관(1)의 구멍(1c)에 접합된 연결구(3)의 중심부내에 가로고정돌기(4b)와 세로고정돌기(4c)가 형성되고 내면에 결합홈부(4d)가 형성된 매설부(4a)를 구비한 금속제호스연결관(4)를 매설하였기 때문에 연결구(3)와 금속제호스연결관(4)의 매설부가 안전하게 결합하여 고정되게 되고 사용중에 이완이 발생할 염려가 없는 장점이 있으며 연결구(3) 외측으로 금속제호스연결관의 호스접속부(4e)가 돌출되므로 온수주입용호스(2) 또는 분배용호스(5)의 끝을 직접 그 접속부에 끼워넣고 공지된 조임링(8)과 체결너트(9)를 체결하여 결합시킬 수 있으며 보일러 중계관 외면에 보온재를 씌우고 보강철판으로 고정시킬 때 연결구 외면에 형성된 수나사부에 체결너트(6)를 조립하여 부착시킬 수 있으므로 금속제호스연결관(4)에 부담을 주지않고 보강철판(7)의 조립이 달성되는 이점이 있고 이로인해 사용중에 금속제호스연결관(4)과 연결구 사이에 이완염려가 없는 제품을 만들 수 있도록 된다.In the present invention as described above, the horizontal fixing protrusion 4b and the vertical fixing protrusion 4c are formed in the center of the connector 3 joined to the hole 1c of the hot water relay pipe 1, and the coupling groove 4d is formed on the inner surface thereof. Since the metal hose connecting pipe 4 having the buried portion 4a having the buried portion is buried, the buried portions of the connector 3 and the metal hose connecting pipe 4 are securely coupled and fixed, and there is no fear of relaxation during use. Since the hose connection part 4e of the metal hose connector pipe protrudes outward from the connector 3, the end of the hot water injection hose 2 or the distribution hose 5 is directly inserted into the connection part, and a known fastening ring ( 8) and the fastening nut (9) can be coupled to each other, and the fastening nut (6) can be assembled and attached to the male screw formed on the outer surface of the boiler relay pipe when the insulation is put on the outer surface of the boiler relay pipe and the metal hose Do not burden the connector (4) The advantage is achieved that the assembly of the reinforcing iron plate (7) and thereby to create a product with no relaxation concerned between the metal hose connector 4 and the connector during use.
