상기와 같이 구성되어 있는 본 발명의 작용관계를 도 2 내지 도 9를 참고하여 설명하면 다음과 같다.Referring to Figures 2 to 9 the working relationship of the present invention configured as described above is as follows.

본 발명에 의한 밸브실(1)은 도 2 내지 도 4에서 보는 바와 같이 밸브실본체(2)의 양측에 신축연결관(100)이 연결 설치되는데, 도 4는 신축연결관(100)의 일실시예를 도시한 것이다.In the valve chamber 1 according to the present invention, as shown in FIGS. 2 to 4, expansion and contraction pipes 100 are installed at both sides of the valve chamber body 2, and FIG. 4 is one of the expansion and connection pipes 100. An example is shown.

이와 같은 신축연결관(100)을 밸브실본체(2)에 연결 설치하고자 하는 경우에는 신축연결관(100)의 전방플랜지(110) 하측에 나사식으로 체결된 높이조절볼트(117)를 풀거나 조여서 높이조절볼트(117)의 하단부가 지면에 접촉되었을 때, 신축연결관(100)의 수평 중심선 높이가 밸브실본체(2)의 측판에 관통 형성된 플랜지삽입홀(5)의 중심선 높이와 일치될 높이만큼 높이조절볼트(117)의 높이를 조절한다.If you want to install such expansion connection pipe 100 to the valve chamber body (2), loosen the height adjustment bolt 117 screwed to the lower side of the front flange 110 of the expansion connection pipe 100 or When the lower end of the height adjustment bolt 117 is in contact with the ground by tightening, the height of the horizontal center line of the flexible connecting pipe 100 is to match the height of the center line of the flange insertion hole 5 formed through the side plate of the valve chamber body 2. Adjust the height of the height adjustment bolt 117 by height.

이 상태에서 신축연결관(100)을 플랜지삽입홀(5)과 인접한 지면에 내려놓은 상태에서 신축연결관(100)의 후방플랜지관(150)만 들면, 전방플랜지(110) 하측의 높이조절볼트(117) 저면이 지면과 접촉된 상태이므로 후방플랜지관(150) 측을 큰 힘 들이지 않고 상측으로 들어올릴 수 있다.In this state, if the rear flange pipe 150 of the flexible connection pipe 100 in a state where the flexible connection pipe 100 is placed on the ground adjacent to the flange insertion hole 5, the height adjusting bolt of the lower side of the front flange 110 (117) Since the bottom surface is in contact with the ground, the rear flange tube 150 may be lifted upward without great force.

이렇게 들어올리는 신축연결관(100)의 후방플랜지관(150)을 밸브실본체(2)의 외측에서 플랜지삽입홀(5)을 통하여 밸브실본체(2)의 내측으로 후방플랜지관(150)의 후방측을 삽입시키는데, 후방플랜지관(150)의 후방측 내측플랜지부(155)의 외경이 플랜지삽입홀(5) 보다 작아서 후방플랜지관(150)의 후방측 내측플랜지부(155)를 플랜지삽입홀(5)을 통하여 밸브실본체(2)의 내측으로 쉽게 삽입된다.The rear flange tube 150 of the expansion and contraction pipe 100 lifted up to the inside of the valve chamber body 2 through the flange insertion hole 5 from the outside of the valve chamber body 2 of the rear flange tube 150 To insert the rear side, the outer diameter of the rear inner flange portion 155 of the rear flange tube 150 is smaller than the flange inserting hole 5, so the flange of the rear inner flange portion 155 of the rear flange tube 150 is inserted. It is easily inserted into the valve chamber body 2 through the hole 5.

그런데, 후방플랜지관(150)의 전방에 형성되는 외측플랜지부(151)는 플랜지삽입홀(5) 보다 외경이 커서 외측플랜지부(151)의 후면이 플랜지삽입홀(5) 외측의 밸브실본체(2) 측면에 걸리게 된다.However, the outer flange portion 151 formed in front of the rear flange tube 150 has a larger outer diameter than the flange insertion hole 5 so that the rear surface of the outer flange portion 151 has a valve body body outside the flange insertion hole 5. (2) caught on the side.

이때, 외측플랜지부(151)의 후면 하측에는 후방플랜지관(150)을 플랜지삽입홀(5)을 통하여 밸브실본체(2)의 내부로 삽입시켰을 때, 외측플랜지부(151)와 플랜지삽입홀(5)이 동심원상태로 놓이게 하는 걸림구(156)가 플랜지삽입홀(5)의 하부측 내주연에 걸리도록 후방으로 돌출되게 설치되어서, 후방플랜지관(150)을 플랜지삽입홀(5)을 통하여 밸브실본체(2)의 내측으로 삽입시키면서 걸림구(156)가 플랜지삽입홀(5)의 하부측 내주연에 걸리도록 하면 외측플랜지부(151)와 플랜지삽입홀(5)이 동심원상태로 놓이게 된다.At this time, when the rear flange tube 150 is inserted into the inside of the valve chamber body 2 through the flange insertion hole 5 in the lower rear side of the outer flange portion 151, the outer flange portion 151 and the flange insertion hole. A locking hole 156 for allowing 5 to be placed in a concentric manner is installed to protrude rearward to catch the inner peripheral edge of the lower side of the flange insertion hole 5, so that the rear flange tube 150 is connected to the flange insertion hole 5. The outer flange portion 151 and the flange inserting hole 5 are concentric in a state where the catching hole 156 is caught by the inner circumference of the lower side of the flange inserting hole 5 while being inserted into the inside of the valve chamber body 2. To be placed.

이 상태에서 외측플랜지부(151)의 후면과 플랜지삽입홀(5)의 전면 외측을 밀착시킨 상태에서 서로가 밀착된 부분(w)을 용접으로 결합하거나, 서로가 겹친 부분을 볼트로 결합 설치하면 밸브실본체(2)의 외측면에 신축연결관(100)을 간편하게 정위치에 설치할 수 있게 되는 것이다.In this state, when the rear surface of the outer flange portion 151 and the front outer surface of the flange insertion hole 5 are in close contact with each other, the parts (w) which are in close contact with each other are welded, or the parts overlapping with each other are installed by bolts. The expansion and contraction tube 100 on the outer side of the valve chamber body (2) is to be easily installed in place.

이와 같이 신축연결관(100)을 밸브실본체(2)의 외측에 설치한 뒤에는 도 9의 (가)(나)에서 보는 바와 같이 작업현장에 맞게 압륜(75)을 이용하여 배관(7)을 신축연결관(100)에 연결하거나, 신축연결관(100)의 외측단에 플랜지형 배관(8)을 연결 설치할 수 있는 것이다.After the expansion connecting pipe 100 is installed on the outside of the valve chamber body 2, the piping 7 is connected to the work site by using the pressure wheel 75 as shown in FIG. 9A. Connected to the flexible connection pipe 100, or can be installed to connect the flange type pipe (8) to the outer end of the flexible connection pipe (100).

위와 같이 배관(7,8)을 설치한 뒤에 종래와 동일하게 지중에 매설하는 밸브실(1)의 외측으로 토사를 메워서 밸브실(1)의 설치작업이 완료되었을 때, 밸브실(1)과 신축연결관(100)에 토압이 작용하나, 밸브실(1)은 전체적으로 금속제를 이용하여 견고하게 제작한 것임에 따라 토압에는 전혀 문제가 되지 않는다.After the pipes 7 and 8 are installed as described above, when the earth and sand are filled to the outside of the valve chamber 1 embedded in the ground in the same manner as before, the valve chamber 1 is completed. Earth pressure acts on the expansion and connection pipe 100, but the valve chamber (1) as a whole made of a solid made of metal does not cause any problem at all.

그런데, 본 발명에서 요부가 되는 도 4에 도시된 신축연결관(100)의 일실시예는 고무재가 포함되어서 외력이나 토압에 의해 압축되는 등의 변형 및 손상을 염려할 수 있으나, 신축연결관(100)의 내부에 금속으로 된 내부구성품, 즉 금속플랜지관(115)과, 후방플랜지관(150)의 전방수평관부(152)와, 전방의 금속플랜지관(115)과 후방의 전방수평관부(152) 사이에 스프링(131)이 연결된 플랜지관 결합체가 고무재로 된 고무몰딩부(132)의 내부에 인서트몰드 방식에 의해 매설되어서 신축연결관(100)이 압축되는 등의 변형 및 손상을 막을 수 있는 것이다.By the way, one embodiment of the flexible connecting tube 100 shown in Figure 4 which is the main part of the present invention may include a rubber material may be deformed and damaged such as being compressed by an external force or earth pressure, but the flexible connecting tube ( Inside the metal 100, that is, the metal flange tube 115, the front horizontal pipe portion 152 of the rear flange tube 150, the front metal flange tube 115 and the front horizontal pipe portion of the rear ( The flange duct joint connected between the springs 131 between the springs 131 is embedded in the rubber molding part 132 made of rubber material to prevent deformation and damage such as the expansion and contraction pipe 100 being compressed. It can be.

이와 같은 상태에서 내진이 발생하거나, 또는 굴착기를 이용하는 등의 작업을 진행하는 과정에서 부주의로 신축연결관(100) 주변을 잘못 건드린 경우에, 본 발명에 포함되는 신축연결관(100)이 신축이 양호한 고무재를 포함하여 구성되어서 신축연결관(100)에 직접적으로 강한 충격이 작용하지 않는 이상 상기 외력 및 내진에 신축연결관(100)이 신축적으로 대응하여 밸브실(1)에 연결되는 배관의 손상을 최소화하게 되는 것이다.In this state, when the earthquake-resistant, or inadvertently touched the expansion connector 100 around the inadvertently in the process of using an excavator or the like, the expansion connector 100 included in the present invention is stretched. The pipe is connected to the valve chamber 1 by elastically responding to the external force and the earthquake resistance, unless a strong impact is applied directly to the flexible connecting pipe 100 is configured to include a good rubber material Will minimize damage.

상기 신축연결관(100)이 고무재로 형성되면서 내측에 스프링(131)이 삽입되어 있음에 따라 위와 같은 내진을 포함한 외력에 신축연결관(100)이 탄력적으로 대응하게 되는 것이다.As the expansion connector 100 is formed of a rubber material, as the spring 131 is inserted into the inner side, the expansion connector 100 elastically corresponds to the external force including the earthquake.

그리고, 도 2, 3 및 도 8에서 보는 바와 같이 밸브실본체(2)의 외부에 밸브실본체(2)의 보강을 위하여 다수개의 보강리브(3)가 바둑판 모양으로 형성되어 인접한 보강리브(3)의 사이에 사각모양으로 외부 한 쪽이 개방되는 공간부(4)가 형성되어 그 공간부(4)에 단열패널(70)을 삽입 부착할 수 있다.2, 3, and 8, a plurality of reinforcing ribs 3 are formed in a checkerboard shape for the reinforcement of the valve chamber body 2 on the outside of the valve chamber body 2 and adjacent reinforcement ribs 3. The space portion 4 is formed in the square between the outer side is opened in one side can be inserted into the heat insulating panel 70 in the space (4).

상기 다수개의 보강리브(3)는 밸브실(1)이 지중에 매설되고 그 위에 도로포장재가 포장되어 중량물의 화물차가 지나가는 경우에도 그 하중을 충분히 견딜 수 있도록 설계하여 제작되어 있다.The plurality of reinforcement ribs 3 are designed and manufactured to sufficiently withstand the load even when the valve chamber 1 is buried in the ground and the road pavement is packed thereon to pass a heavy truck.

이 상태에서 바둑판 모양으로 형성되는 공간부(4)에 후면에 점착층(71)이 구비된 판형 단열패널(70)을 간편하게 삽입 부착할 수 있다. 이렇게 각각의 공간부(4)에 단열패널(70)를 삽입 부착시켰을 때, 보강리브(3)의 두께부분이 노출되게 되고 보강리브(3)와 단열패널(70)이 접하는 부분에 틈새가 생겨 그 틈새로 땅속의 물기가 스며들 수 있게 된다.In this state, the plate-shaped heat insulation panel 70 having the adhesive layer 71 on the rear side can be easily inserted into the space 4 formed in the shape of a checkerboard. When the insulation panel 70 is inserted and attached to each of the spaces 4, the thickness portion of the reinforcing rib 3 is exposed and a gap is formed in the portion where the reinforcing rib 3 and the insulation panel 70 contact each other. The gap allows water to soak in the ground.

본 발명에서는 이를 감안하여 도 8에서와 같이 바둑판 모양으로 삽입 부착된 인접한 단열패널(70)의 외곽에 틈새커버 테이프(74)를 부착시켜서 보강리브(3)와 그 외측의 단열패널(70)과의 틈새를 커버하여 땅속의 물기가 상기 틈새로 스며들지 않게 한다.In view of this, in the present invention, the gap cover tape 74 is attached to the outer side of the adjacent insulation panel 70 inserted and inserted in a checkerboard shape as shown in FIG. Cover the gaps of the ground so that water in the ground does not penetrate into the gaps.

이렇게 지중에 매설된 밸브실(1)의 외부에 단열패널(70)이 부착 설치됨에 따라 동절기에 땅속의 온도가 낮아지는 경우에도 땅속의 냉기가 밸브실(1)의 내측으로 전도되는 것을 최소화하여 밸브실(1) 내측의 결로 방지에 도움을 주게 되고, 그 내부에 설치된 밸브 등이 동파되지 않게 하는 것이다.As the heat insulation panel 70 is attached to the exterior of the valve chamber 1 embedded in the ground, even when the temperature of the ground decreases in winter, the cold air in the ground is conducted to the inside of the valve chamber 1 to minimize the This helps to prevent condensation inside the valve chamber 1 and prevents the valve and the like installed therein from freezing.

도 7에 도시된 신축연결관(100)의 이실시예의 경우에도 도 4에 도시된 신축연결관(100)의 일실시예와 동일하게 밸브실본체(2)에 형성된 플랜지삽입홀(5)에 후방플랜지관(150)을 삽입시키면서 밸브실본체(2)의 측판에 고정 결합시키는 것이 동일하고, 일실시예에서 스프링(131)이 매설된 부분이 내진 등의 외력에 휘어지면서 그 외력에 대응하는 것 대신에 이실시예에서는 위와 같이 휘어지는 부분이 주름관 형태로 형성된 신축부(130)에서 그 역할을 하는 것이 동일하므로, 이실시에에 대한 작용관계에 대한 구체적인 설명을 생략한다.In this embodiment of the flexible connecting pipe 100 shown in Figure 7 also in the flange insertion hole 5 formed in the valve chamber body 2 in the same way as the embodiment of the flexible connecting pipe 100 shown in FIG. It is the same as fixedly coupled to the side plate of the valve chamber body 2 while inserting the rear flange tube 150, in one embodiment the portion where the spring 131 is buried in the external force such as seismic resistance corresponding to the external force In this embodiment instead of the same, because the same part to play the role in the stretched portion 130 is formed in the corrugated pipe shape as described above, a detailed description of the working relationship for this embodiment will be omitted.
