The present invention relates to a water pipe connection structure that greatly improves watertightness by applying a pressing force to the entire joint portion of the pipe.

종래 상수도관 연결구조는 다수의 패킹과 나사 결합부 및 너트를 이용하여 결합하는 구조로 되어 있었기 때문에 상수도관의 연결작업이 매우 번거롭고 작업이 지연되는 단점을 지니고 있었다.The conventional water pipe connection structure has a disadvantage that the connection work of the water pipe is very cumbersome and the work is delayed because it has been configured to combine using a plurality of packing and screw coupling portion and nut.

또한, 종래 상수도관 연결구조는 패킹이 설치된 부위만 수밀을 유지하는 구조로 되어 있을 뿐 전체적인 수밀 구조를 갖추고 있지 않았기 때문에 맥동에 의해 상수도관에 급격한 수압 변화가 발생되는 경우 패킹재가 쉽게 파손되어 누수되는 문제점을 갖고 있었다.In addition, the conventional water pipe connection structure is a structure in which only the part where the packing is installed maintains watertightness, but does not have an overall watertight structure, so when a sudden water pressure change occurs in the water supply pipe due to pulsation, the packing material is easily broken and leaked. I had a problem.

Trapezoidal annular pressing grooves 22 and 32 are formed on the outer circumferential surface thereof, and a galvanized hard protective layer 42 is installed on the inner circumferential surface of the socket 40 in which the reinforcing iron core 41 is embedded. The left and right outer peripheral surfaces of the 40 form one-way annular locking protrusions 43 and 44 that are caught by the one-way annular locking grooves 21 and 31 formed in the water supply pipes 20 and 30. 20 and 30 are formed on the outer circumferential surface of the socket 40, the screw coupling portion 45 is located between both ends, and a plurality of stud bolts 46a and 46b are radially welded to the reinforcing iron core 41. The flexible pressing layer 52 is formed on the inner circumferential surface of the arc-shaped split cover 50 divided into equal angles, and the annular pressing grooves 22 and 32 are formed on the left and right sides of the inner circumferential surface of the soft pressing layer 52. The engaging trapezoidal annular pressing protrusions 54 and 56 are formed, and through holes 58a and 58b are formed in the split cover 50 to penetrate the stud bolts 46a and 46b. The split cover 50 is coupled to the water supply pipes 20 and 30 and the socket 40 by pressing the nut 60 and 62 coupled to the 46a and 46b. That is, the socket 40 is formed on the outer periphery to be combined with other members.

여기서 나사 결합부(45)의 외주면에 도 2와 같이 나사산 형태의 복렬 삼각홈(45g)을 형성하고, 상기 연질가압층(52)의 내주면 중앙에 상기 복렬 삼각홈(45g)에 맞물리는 나사산 형태의 복렬 삼각돌기(52g)를 형성하여 구성한다.Here, a threaded double triangular groove (45g) is formed on the outer circumferential surface of the screw coupling portion 45, and the thread shape is engaged with the double triangular groove (45g) in the center of the inner circumferential surface of the soft pressing layer (52).

이하 본 발명에 따른 작용을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 1 내지 도 4에 도시된 바와 같이 본 발명의 조립 과정은 소켓(40)의 양단을 좌우 양측의 상수도관(20)(30)으로 밀어 넣게 되면, 소켓(40)에 형성되어 있는 일방향 환형 걸림돌기(43)(44)가 고무와 같은 연질로 형성되어 있기 때문에 압축에 의해 탄성변형되면서 상수도관(20)(30)의 내주면으로 진입된다.As shown in FIGS. 1 to 4, when the assembly process of the present invention pushes both ends of the socket 40 into the water supply pipes 20 and 30 on both the left and right sides, one direction is formed in the socket 40. Since the annular engaging projections 43 and 44 are formed of a soft material such as rubber, they are elastically deformed by compression and enter the inner circumferential surface of the water supply pipes 20 and 30.

이후 일방향 환형 걸림돌기(43)(44)가 상수도관(20)(30)에 형성되어 있는 일방향 환형 걸림홈(21)(31)에 도달하게 되면, 탄성복원력에 의해 원형으로 복원되면서 일방향 환형 걸림홈(21)(31)에 결합되어 걸리게 된다.Then, when the one-way annular locking projections 43 and 44 reach the one-way annular locking grooves 21 and 31 formed in the water pipes 20 and 30, the one-way annular locking is restored to a circular shape by the elastic restoring force. Engaged in the groove (21) (31) is caught.

그 다음 4개로 분할된 분할커버(50)를 소켓(40)과 상수도관(20)(30)의 외주면에 밀착시키면서 동시에 분할 커버(50)에 형성되어 있는 관통 구멍(58a)(58b)을 소켓(40)으로부터 돌출된 스터드 볼트(46a)(46b)에 맞추게 되면, 스터드 볼트(46a)(46b)가 관통 구멍(58a)(58b)을 통과하여 분할 커버(50) 외측으로 돌출되며, 분할커버(50)의 연질가압층(52)에 형성된 환형가압돌기(54)(56)가 상수도관(20)(30)의 외주면에 형성되어 있는 환형 가압홈(22)(32)에 끼워지게 되고, 동시에 분할 커버(50)의 연질가압층(52) 내주면에 형성되어 있는 복렬 삼각돌기(52g)가 소켓(40)에 형성된 나사 결합부(45)의 외주면에 형성된 복렬 삼각홈(45g)에 맞물리게 된다.Then, the through-holes 58a and 58b formed in the split cover 50 are simultaneously held in close contact with the outer circumferential surfaces of the socket 40 and the water pipes 20 and 30. When fitted to the stud bolts 46a and 46b protruding from the 40, the stud bolts 46a and 46b protrude out of the split cover 50 through the through holes 58a and 58b, and the split cover. The annular pressing protrusions 54 and 56 formed in the soft pressing layer 52 of the 50 are fitted into the annular pressing grooves 22 and 32 formed on the outer circumferential surface of the water pipe 20 and 30, At the same time, the double row triangular protrusion 52g formed on the inner circumferential surface of the soft pressing layer 52 of the split cover 50 is engaged with the double row triangular groove 45g formed on the outer circumferential surface of the screw engaging portion 45 formed on the socket 40. .

이후 소켓(40)의 외부로 돌출된 스터드 볼트(46a)(46b)에 너트(60)(62)를 결합하여 조이게 되면, 4개의 분할커버(50)가 상수도관(20)(30)과 소켓(40)을 중심을 향해 가압하게 되고, 분할커버(50)의 연질 가압층(52)에 형성된 환형 가압돌기(54)(56)가 상수도관(20)(30)의 외주면에 형성된 환형 가압홈(22)(32)에 더욱 밀착되는 동시에 연질 가압층(52)의 내주면에 형성된 복렬 삼각돌기(52g)가 나사 결합부(45)에 형성된 복렬 삼각홈(45g)에 더욱 밀착하여 수밀성이 향상된다.Then, when the nut 60, 62 is coupled to the stud bolts 46a and 46b protruding out of the socket 40, the four split covers 50 are connected to the water pipes 20 and 30 and the socket. 40 is pressed toward the center, and the annular pressing protrusions 54 and 56 formed in the soft pressing layer 52 of the split cover 50 are formed in the annular pressing groove formed on the outer circumferential surface of the water supply pipe 20 and 30. The double triangular protrusion 52g formed on the inner circumferential surface of the soft pressing layer 52 is further in close contact with the (22), 32, and closer to the double triangular groove 45g formed on the screw coupling portion 45, thereby improving watertightness. .

또한, 너트(60)(62)와 스터드 볼트(46a)(46b)를 더 조이게 되면, 소켓(40)의 외주면에 형성된 일방향 환형 걸림돌기(43)(44)가 상수도관(20)(30)의 내주면에 형 성되어 있는 일방향 환형 걸림홈(21)(31)에 밀착하여 수밀성이 향상된다.In addition, when the nuts 60 and 62 and the stud bolts 46a and 46b are further tightened, the one-way annular engaging protrusions 43 and 44 formed on the outer circumferential surface of the socket 40 become water conduits 20 and 30. It is in close contact with the one-way annular engaging grooves 21 and 31 formed on the inner circumferential surface of the watertightness is improved.

즉, 환형 가압돌기(54)(56)가 형성된 연질 가압층(52)과 일방향 환형 걸림돌기(43)(44)가 형성된 소켓(40)이 모두 고무와 같은 연질재로 형성되어 있기 때문에 밀착력이 향상되는 것이며, 복렬 삼각돌기(52g)가 형성된 연질가압층(52)과 복렬 삼각홈(45g)이 형성된 나사 결합부(45)가 모두 고무와 같은 연질재로 구성되어 있기 때문에 너트(60)(62)와 스터드 볼트(46a)(46b)에 의해 밀착력이 향상된다.That is, since both the soft pressing layer 52 in which the annular pressing protrusions 54 and 56 are formed and the socket 40 in which the one-way annular locking protrusions 43 and 44 are formed are made of a soft material such as rubber, Since the soft pressing layer 52 having the double triangular protrusion 52g and the screw engaging portion 45 having the double triangular groove 45g are all made of a soft material such as rubber, the nut 60 ( Adhesion is improved by 62 and stud bolts 46a and 46b.

한편, 위와 같은 상태에서 상수도관(20)(30)을 통해 물이 압송되면, 물은 일측 상수도관(20)으로부터 소켓(40)의 내주면에 형성된 경질 보호층(42)을 통해 반대편의 상수도관(30)으로 흐르게 되며, 이때 상수도관(20)(30)과 소켓(40)은 수밀을 유지하고 있기 때문에 누수의 염려가 없게 된다.On the other hand, when water is pumped through the water supply pipes 20 and 30 in the above state, the water is opposite to the water supply pipe through the hard protective layer 42 formed on the inner circumferential surface of the socket 40 from the water supply pipe 20 on one side. 30, the water pipes 20 and 30 and the socket 40 are kept watertight so that there is no fear of water leakage.

이 과정에서 소켓(40)의 내주면에 형성되어 있는 경질 보호층(42)은 아연도금되어 있기 때문에 소켓(40) 내측이 부식되는 것을 방지하게 된다.In this process, since the hard protective layer 42 formed on the inner circumferential surface of the socket 40 is galvanized, the inside of the socket 40 is prevented from being corroded.

또, 소켓(40)에 매설된 보강 철심(41)은 소켓(40)에 작용되는 결합력과 수압에 의해 소켓(40)이 크게 변형되는 것을 방지하여 소켓(40)의 형태를 유지하게 되며, 너트(60)(62)와 스터드 볼트(46a)(46b)가 결합될 때 소켓(40)에 힘이 고르게 분포하도록 하는 작용도 하게 된다.In addition, the reinforcing iron core 41 embedded in the socket 40 prevents the socket 40 from being greatly deformed by the coupling force and the hydraulic pressure applied to the socket 40 to maintain the shape of the socket 40, and the nut When the 60 and 62 and the stud bolts 46a and 46b are coupled, the force is evenly distributed to the socket 40.

또한, 상수도관(20)(30)을 보수할 때 스터드 볼트(46a)(46b)에 결합되어 있는 너트(60)(62)를 돌려서 풀게 되면, 상수도관(20)(30)을 간단히 분리할 수 있게 되어 보수가 간편하게 된다.In addition, if the nut 60, 62 coupled to the stud bolts 46a and 46b is loosened when the water pipes 20 and 30 are repaired, the water pipes 20 and 30 can be easily removed. It becomes possible and maintenance becomes easy.

이상에서 설명한 바와 같은 본 발명은 등각도로 분할된 분할커버에 의해 상수도관을 결합하는 구조로 되어 있기 때문에 상수도관의 연결 및 분리가 간편하게 되어 상수도관 연결작업을 신속하게 마치는데 도움을 줄 수 있는 효과가 있으며, 소켓의 내주면에 형성되어 있는 경질보호층이 아연도금되어 있기 때문에 부식으로부터 안전하고, 분할 커버와 소켓을 결합할 때 복렬 삼각돌기와 복렬 삼각홈이 서로 맞물려 가압되는 구조로 되어 있으므로 수밀성을 크게 향상시킬 수 있는 효과가 있다.As described above, the present invention has a structure in which water pipes are coupled by a split cover divided into equal angles, thereby facilitating connection and separation of water pipes, thereby helping to quickly complete the water pipe connection work. Since the hard protective layer formed on the inner circumferential surface of the socket is galvanized, it is safe from corrosion, and when the split cover and the socket are joined, the double triangular protrusion and the double triangular groove are engaged with each other and pressurized, so that the watertightness is greatly increased. There is an effect that can be improved.
