통상적인 용접이나 플랜지결합에 의한 배관연결방식의 문제점을 해소하기 위하여 안출된 종래의 배관용 연결구는 도 1과 도 2에 도시되어 있는 바와 같이, 양단부에 플랜지(2a)가 각각 절곡형성되며 일측에 길이방향의 절개부가 형성된 원통관형상으로 이루어지고, 상기 절개부의 양측단부외측에는 클램핑볼트(7)가 체결되는 볼트체결봉(3)(4)이 각각 삽입설치된 체결봉설치부(5)(6)가 형성되며 절개부의 일측단부내측에는 양단부에 플랜지(8a)가 절곡형성된 슬라이드부(8)가 고정설치된 하우징(2)과, 상기 하우징(2)의 내측에 삽입설치되는 것으로, 양단부에 원추형 링안착면(9a)(9b)이 각각 형성된 원통관형상으로 이루어지며 양단부의 내측둘레에는 끝단부에 덧살(12)이 구비된 밀폐날개부(10)(11)가 각각 형성되고, 상기 밀폐날개부(10)(11)의 덧살(12)에는 밀폐날개부(10)(11)에 의해 각각 형성되는 가압공간부(13)(14)를 외부와 연통시키게 되는 복수개의 통공(12a)이 관통형성된 고무슬리브(9)와, 상기 하우징(2)의 내측에 삽입설치된 고무슬리브(9)의 링안착면(9a)(9b)에 각각 설치되는 것으로, 원추형으로 만곡되게 형성된 C자형 링형상으로 이루어지며 내측단부의 둘레에는 톱니형상의 파이프고정부(17)가 형성된 그립링(15)(16)으로 구성된다.In order to solve the problem of the pipe connection method by the conventional welding or flange coupling, as shown in Figs. 1 and 2, the conventional pipe connector has a flange (2a) is bent at each end and formed on one side It consists of a cylindrical tube shape formed with a longitudinal cut, and the bolt rods (3) (4) to which the clamping bolt (7) is fastened to the outer side of both ends of the cut portion, respectively, the rod mounting portion (5) (6) ) Is formed and a housing (2) having a slide (8) having a flange (8a) bent at both ends is fixedly installed at one end of the incision, and is inserted into the housing (2), and has a conical ring at both ends. It is made of a cylindrical tube shape each having a seating surface (9a) (9b) is formed in the inner circumferential end of the both ends are formed with sealing wings (10) (11) having a grate (12) at the ends, respectively, the sealing wing (10) (11) seals (12) on the seal A rubber sleeve 9 through which a plurality of through holes 12a through which the pressurized space portions 13 and 14 respectively formed by the opening portions 10 and 11 communicate with the outside is formed, and the inner side of the housing 2. It is installed on the ring seating surface (9a) (9b) of the rubber sleeve (9) inserted into each, it is made of a C-shaped ring shape formed to be curved in a conical shape, the toothed pipe fixing part 17 around the inner end It is composed of a grip ring (15, 16) is formed.

이와 같이 구성되는 종래의 배관용 연결구는 도 3에 도시되어 있는 바와 같이 연결하고자 하는 파이프(20)(21)의 단부사이에 삽입설치된 후 하우징(2)의 체결봉설치부(5)(6)에 각각 설치된 볼트체결봉(3)(4)에 클램핑볼트(7)가 체결됨에 따라 하우징(2)이 슬라이드부(8)를 따라 원주방향으로 점차 조여지게 되는 동시에 하우징(2)내측에 삽입설치된 고무 슬리브(9)가 파이프(20)(21)의 외측면에 밀착되므로써 견고한 밀폐상태를 유지할 수 있게 되며, 또한 상기 고무 슬리브(9)의 양단부에 각각 삽입설치된 그립링(15)(16)이 원주방향으로 조여지게 되면서 파이프(20)(21)를 고정시키게 되므로써 견고한 연결상태를 유지할 수 있게 된다.Conventional piping connector configured as described above is inserted between the ends of the pipe 20, 21 to be connected as shown in Figure 3 and then the mounting rod mounting portion (5) (6) of the housing (2) As the clamping bolts 7 are fastened to the bolt fastening rods 3 and 4 respectively installed on the housings 2, the housings 2 are gradually tightened in the circumferential direction along the slides 8 and inserted into the housings 2. Since the rubber sleeve 9 is in close contact with the outer surfaces of the pipes 20 and 21, it is possible to maintain a tightly sealed state, and the grip rings 15 and 16 respectively inserted into both ends of the rubber sleeve 9 are provided. By being tightened in the circumferential direction it is possible to maintain a solid connection state by fixing the pipe (20, 21).

또한, 종래의 배관용 연결구는 파이프(20)(21)내부의 유체가 단부로 유출되어 하우징(2)의 내부에 삽입설치된 고무 슬리브(9)의 내부로 유입된 후, 고무 슬리브(9)의 양단부 내측둘레에 형성된 밀폐날개부(10)(11)의 덧살(12)에 형성된 통공(12a)을 통해 가압공간부(13)(14)로 유입되어 고무 슬리브(9)의 밀폐날개부(10) (11)를 가압하게 되므로써, 고무 슬리브(9)의 밀폐날개부(10)(11)가 파이프(20) (21)의 외측면에 더욱 더 견고하게 밀착되어 안정된 밀폐상태를 유지할 수 있게 된다.In addition, in the conventional pipe fitting, the fluid inside the pipes 20 and 21 flows out to the ends and flows into the rubber sleeve 9 inserted into the housing 2, and then the rubber sleeve 9 It enters the pressurized space 13 and 14 through the through hole 12a formed in the grate 12 of the sealed wings 10 and 11 formed at the inner circumference of both ends, and the sealed wing 10 of the rubber sleeve 9 is introduced. By pressurizing the 11, the sealing wing portions 10 and 11 of the rubber sleeve 9 can be more firmly adhered to the outer surfaces of the pipes 20 and 21 to maintain a stable sealing state. .

그러나, 상기와 같은 종래의 배관용 연결구는 보다 높은 압력조건에서 사용될 경우 고무 슬리브(9)의 밀폐날개(10)(11)를 가압하기 위하여 가압공간부(13) (14)로 유입된 고압의 유체에 의해 고무 슬리브(9)의 양단부가 팽창되어 고무 슬리브(9)의 양단부에 삽입설치된 그립링(15)(16)이 변형, 즉 원추형으로 만곡형성된 그립링(15)(16)이 평판상으로 펴지게 되면서 그립링(15)(16)보다 상대적으로 강도가 약한 하우징(2)을 변형시키게 되므로써, 그립링(15)(16)의 파이프 고정력이 현저히 저하되어 파이프(20)(21)가 이탈하게 되는 치명적인 문제점이 있었다.However, the above-described conventional pipe connector is a high pressure flow into the pressurized space (13) 14 to pressurize the sealing wings (10) (11) of the rubber sleeve (9) when used under higher pressure conditions. Both ends of the rubber sleeve 9 are inflated by the fluid, and the grip rings 15 and 16 inserted into the both ends of the rubber sleeve 9 are deformed, i.e., the grip rings 15 and 16 are curved in a conical shape. By unfolding and deforming the housing 2, which is relatively weaker than the grip rings 15, 16, the pipe holding force of the grip rings 15, 16 is significantly lowered so that the pipes 20, 21 are There was a fatal problem that was thrown away.

이와 같은 문제점을 해소하기 위하여 상기 하우징(2)이나 그립링(15)(16)의 두께를 증대시켜 강도를 보강하려는 노력이 있었으나, 하우징(2)이나 그립링(15) (16)의 두께를 증대시킬 경우 가공성이 떨어져 생산성이 현저히 저하되는 문제가 있었으며, 또한 상기 그립링(15)(16)의 내측단부에 톱니형상으로 형성된 파이프고정부(17)의 형상을 다양하게 변경하여 파이프 고정력을 강화시키려는 시도가 있었지만 그립링(15)(16)이 변형될 경우에는 전혀 실효를 거두지 못하고 있는 실정이었다.In order to solve such a problem, there have been efforts to reinforce the strength by increasing the thickness of the housing 2 or the grip rings 15 and 16, but the thickness of the housing 2 or the grip rings 15 and 16 has been increased. When increasing, there was a problem that the workability is poor, productivity is significantly reduced, and the shape of the pipe fixing portion 17 formed in the sawtooth shape at the inner end of the grip ring (15) (16) in various ways to strengthen the pipe fixing force Attempts have been made, but the grip ring 15, 16 has been deformed at all.

상기 문제점을 해결하기 위하여 본 고안은 일측에 길이방향으로 형성된 절개부의 양측 단부에 클램핑볼트가 체결되는 볼트체결부가 마주보게 형성되고 절개부의 일측 단부에는 슬라이드부가 고정설치된 원통관형상의 하우징과, 하우징의 내측에 삽입설치되는 고무 슬리브와, 하우징내측에 삽입설치된 고무 슬리브의 양단부에각각 삽입설치되는 그립링으로 이루어진 배관용 연결구를 구성하되, 상기 고무 슬리브의 양단부와 그립링사이에 그립링의 강도를 보강하는 보강링이 각각 삽입설치되도록 하므로써, 배관용 연결구를 이용한 배관연결시 연결구의 내부에 가해지는 높은 유체압력하에서도 파이프를 고정시키는 그립링이 변형되지 않고 견고한 고정상태를 유지할 수 있게 하여 파이프의 이탈을 방지할 수 있도록 하는 것을 기술적 과제로 한다.In order to solve the above problems, the present invention has a cylindrical bolt-shaped housing in which a clamping bolt is fastened to both ends of a cutout formed in a longitudinal direction on one side thereof, and a slide is fixed at one end of the cutout, and a housing of Comprising a pipe coupling member consisting of a rubber sleeve inserted into the inside and a grip ring respectively inserted into both ends of the rubber sleeve inserted into the housing, the strength of the grip ring between the end of the rubber sleeve and the grip ring Since the reinforcing rings are inserted and installed, the grip ring for fixing the pipe can be maintained without being deformed even under the high fluid pressure applied to the inside of the pipe when the pipe is connected by using the pipe connector so that the pipe can be separated from the pipe. The technical problem is to make it possible to prevent the problem.
