본 고안은 관의 직경에 비하여 관의 육부두께가 비교적 얇은 스테인레스 강관과 같은 박육관의 연결장치에 관한 것이다.The present invention relates to a connecting device of a thin tube such as a stainless steel tube of which the thickness of the tube is relatively thin compared to the diameter of the tube.
수도관등으로 사용되는 통상의 철관을 관의 육부두께가 비교적 두꺼워 관연결시관의 연결단부에 나사부를 형성하고 그 나사부에 테프론 수지테이프나 마사 등의 수밀부재를 감은 다음에 T형 또는 L형의 주철제 연결구 본체에 형성된 연결나사부에 나사끼움하여 연결하였는바, 이와 같은 철관은 비교적 연결조립은 용이한 반면에 관로상에 슬럿지가 생겨 위생상으로나 내식성에서 문제가 있으며 주철제 연결구 본체의 육부내의 기공부가 있거나 또는 철제연결구 자체의 빠른 부식 및 관로상의 빠른 부식으로 인하여 내고압성이나 내부압성 및 내구성이 떨어지고 관연결부에서 누수가 발생하는 등의 문제점이 있었다.Ordinary steel pipes used for water pipes are relatively thick in the thickness of the pipes, and at the time of pipe connection, threaded parts are formed at the connecting ends of the pipes, and watertight members such as Teflon resin tape or martha are wound on the threads, and cast irons of T or L type are used. The steel pipe is screwed into the connection screw part formed in the connector body, and this steel pipe is relatively easy to assemble and connect, but there is a problem in hygiene and corrosion resistance due to sludge on the pipe line. Or, due to the rapid corrosion of the steel connector itself and the rapid corrosion on the pipe, there was a problem such as high pressure resistance, internal pressure and durability are deteriorated and water leakage occurs in the pipe connection.
따라서, 근래에 이르러 전술의 철관에서 파생되는 여러가지의 문제점을 해결하고자 경량이면서도 내식성이나 내압성 및 내구성이 우수하고 위생상으로도 인체에 무해한 박육스테인레스 강관을 배관자재로 이용하는 방안이 제안되었으나 육부가 비교적 얇은 스테일레스 강관에는 연결단부에 접속나사를 형성하기 불가능하므로 철관과는 다른 연결방법을 채용하지 아니하면 관연결이 불가능하였다.Therefore, in recent years, in order to solve various problems derived from the aforementioned steel pipe, a method of using a thin stainless steel pipe, which is light weight, excellent in corrosion resistance, pressure resistance, durability, and hygiene, harmless to the human body as a piping material, has been proposed. Since stainless steel pipes cannot form connection screws at connection ends, pipe connection was impossible unless a different connection method was used.
따라서, 현재 스테인레스 강관과 같은 박육관을 연결하는 방법으로는 국내실용신안공고번호 제85-328호 및 국내 특허공고번호 제90-7403호에서 알려진 바와 같이 박육관의 연결단부 외주면에 환상 돌륜부를 돌출형성하고 그 돌륜부를 형성한 연결단부를 패킹으로 포위하여 경첩형 금속밴드를 조여 붙이거나 연결구 본체 내주면에 패킹링 끼움홈과 돌륜부 끼움홈 및 돌륜부 지지턱을 형성하여 그 내부에 돌륜부를 가지는 박육관의 연결단부를끼우고 연결구 본체의 내주면 나사부에 내단부가 돌륜부의 관축방향으로의 이탈을 방지하도록 체결링을 나사끼움 부착 고정하는 방법을 사용하였는바, 전자의 경우는 양 연결단부 외주면 전체를 패킹이 포위하고 있어서 수밀성의 면에서는 양호하지만 관축방향으로의 이탈력에 대하여서는 그 지지력이 취약하고, 후자의 경우에는 관축방향으로의 이탈에 대한 억제력은 크지만 패킹은 단지 끼움홈에 끼워져 자체 신축 탄력성에 의해서만 수밀성을 나타내므로 관로상에 고압이나 부압이 걸릴 때 누수의 염려가 있으며, 또한 양자 모두가 패킹을 지정위치에 미리 맞추어 끼워넣고 그 다음에 관을 경첩형 금속밴드나 연결구 본체를 이용하여 연결조립하는 과정을 거치는 것이므로 연결조립 시공이 번거로운 불편 점도 있었다.Therefore, as a method of connecting a thin tube such as a stainless steel pipe at present, annular protrusions are formed on the outer circumferential surface of the connecting end of the thin tube, as known from Korean Utility Model Publication No. 85-328 and Korean Patent Publication No. 90-7403. The connecting end part formed with the wheel part is surrounded by a packing to fasten the hinged metal band, or a packing ring fitting groove, a wheel wheel fitting groove and a wheel support jaw are formed on the inner circumferential surface of the connector body to connect the thin tube having the wheel wheel therein. In the case of the former, the packing surrounds the entire outer circumferential surface of both connecting ends.In the former case, the fastening ring is screwed to the inner circumferential surface of the connector body to prevent the inner end from deviating in the tubular direction. It is good in terms of watertightness, but its supporting force is weak against the separation force in the tube axis direction, In case of the ruler, the restraint against the deviation in the tube direction is large, but the packing is only inserted into the fitting groove and shows watertightness only by its elasticity.Therefore, there is a risk of leakage when high pressure or negative pressure is applied to the pipeline. After fitting into the designated position in advance and then through the process of assembling the tube using a hinged metal band or connector body, connection assembly construction was cumbersome inconvenience.
본 고안의 목적은 전술의 종래 박육관 연결장치의 문제점을 개선한 새로운 형태의 연결장치를 제공하기 위한 것이다.An object of the present invention is to provide a new type of connecting device that improves the problems of the conventional thin tube connecting device described above.
본 고안은 스테인레스 단조 가공품으로 형성한 연결구 본체의 연결부 내주면에 관접속단부턱과 패킹 끼움부 및 연결 암나수부를 형성하며 그 연결부내에 돌륜부를 형성한 박육스테인레스 강관을 끼우고 숫나사부가 형성된 체결링으로 체결 고정함에 있어서, 패킹 끼움부를 암나사부의 나사산 높이와 동일면으로 형성함과 더불어 체결링의 내주면에 경사걸림턱과 내측으로 연장된 패킹가압연장 단부를 형성하여 체결링이 연결구 본체의 암나사부에 나사끼움 고정될 때 박육관의 돌륜부가 경사 걸림턱에 지지되어 관축방향으로의 이탈이 방지될 뿐아니라 패킹이 박육관의 돌륜부와 함께 내측으로 연장된 체결링의 가압 연장 단부에 의하여 충분히 가압력을 받아 수밀성이 향상되어 단순히 연결구 본체에 대하여 패킹과 박육관 및 체결링을 순차로 끼워 맞추는 간단한 조립 기공방법에 의하여 조립이 완료되도록 형성하므로서 본 고안의 소기의 목적이 달성되도록 안출한 것인바, 이하 본 고안을 도면에 의하여 설명하면 다음과 같다.The present invention forms a pipe end end, a packing fitting part and a connecting female thread on the inner circumferential surface of the connector main body formed of a stainless forged workpiece, and inserts a thin stainless steel pipe formed with a wheel ring in the connection part and fastens it with a fastening ring formed with a male thread. In fixing, the packing fitting part is formed in the same plane as the thread height of the female screw part, and the inclined locking jaw and the packing pressing extension end extending inward are formed on the inner circumferential surface of the fastening ring to fix the fastening ring to the female screw part of the connector body. When the protrusion of the thin tube is supported by the inclined locking jaw to prevent the deviation in the tube axis direction, the packing is sufficiently pressurized by the pressurized extension end of the fastening ring extending inward together with the protrusion of the thin tube to improve the watertightness. Simply insert the packing, thin pipe and fastening ring with respect to the connector body By assembling to form a complete assembly by a simple assembly pore method to achieve the intended purpose of the present invention bar, the present invention is described by the following drawings.
