본 발명은 신축수단이 구비된 신축밸브에 관한 것으로, 더욱 상세하게는 밸브의 일측 출입관부에 볼 조인트(ball joint)형태의 회전연결관을 설치하고, 회전연결관의 네크부 외측 단부에는 신축연결관을 연결 설치하여 신축밸브을 구성함으로써, 지반침하나 지진과 같은 진동을 포함한 외력이 작용하는 경우에 유체관로(管路)에 연결된 본 발명에서 회전연결관과 신축연결관이 상기 진동을 포함한 외력에 이중으로 대응하여 관로의 손상을 최소화하기 위한 것이다.[0001] The present invention relates to a telescopic valve provided with a telescopic means, and more particularly to a telescopic valve having a ball joint-type connecting tube at one end of a valve, In the present invention, when the external force including vibration such as earthquake or earthquake acts on the pipe, the rotary connector and the expansion joint pipe connected to the fluid pipe are connected to the external force including the vibration Thereby minimizing damage to the pipeline.

도 1은 종래고안을 나타내는 단면도로서, 실용신안등록 제20-234934호(고안의 명칭 : 벨로우즈형 신축 밸브)로 알려지고 있다.1 is a cross-sectional view showing a conventional design, and is known as a utility model registration No. 20-234934 (design name: bellows type expansion valve).

상기 종래고안은 도 1에서 보는 바와 같이 밸브몸체(1)의 일측 플랜지(2) 내주연에 패킹(3)을 가압하는 가압링(4)과 밸브몸체(1)의 내경 안으로 삽입되는 유동관(5)을 가지는 유동플랜지(9)를 볼트(6)와 너트(7)로서 체결한 것에 있어서, 유동플랜지(9)의 유동관(5)에 고품질의 스텐레스 강판을 원통으로 밴딩 가공하여 형성한 벨로우즈(8)를 일체로 부착하여서 됨을 특징으로 하는 구조이다.1, the conventional device has a pressurizing ring 4 for pressurizing the packing 3 at the periphery of one flange 2 of the valve body 1 and a flow pipe 5 inserted into the inside diameter of the valve body 1 ) Formed by bending a high-quality stainless steel plate into a cylindrical shape in the flow pipe (5) of the flow flange (9), and a bellows (8) formed by bending a high- ) Are integrally attached to each other.

이와 같이 된 종래고안은 밸브몸체(1)의 일측 플랜지(2)에 밸브몸체(1)의 내경 안으로 삽입되는 유동관(5)을 가지는 유동플랜지(9)를 볼트(6)와 너트(7)로 체결한 것이므로, 밸브의 관접시 볼트(6)와 너트(7)를 풀어 유동플랜지(9)의 삽입길이를 조절하므로 서 밸브의 면간 거리를 배관의 필요에 따라 조정할 수 있다.The conventional design as described above allows the flow flange 9 having the flow pipe 5 inserted into the inside diameter of the valve body 1 to the one flange 2 of the valve body 1 to be fixed to the bolt 6 and the nut 7 Therefore, by adjusting the insertion length of the flow flange 9 by loosening the pipe plate bolt 6 and the nut 7 of the valve, the distance between the plates can be adjusted according to the need of the pipe.

또한, 벨로우즈(8)가 관로를 통하는 유체의 온도 및 외기에 따른 온도 변화 또는 유체나 지반의 진동 및 축방향의 신축에 대한 관의 팽창과 수축을 흡수하게 됨에 따라지반이 침하되거나 지진과 같은 진동이 발생시 밸브몸체 (1)와 분리된 유동플랜지(9)의 변형을 벨로우즈(8)의 신축력에 의해 차단하도록 한 것이다.In addition, as the bellows 8 absorbs the expansion and contraction of the tube due to the temperature change due to the temperature of the fluid and the outside air, the vibration of the fluid or the ground, and the expansion and contraction of the tube in the axial direction, The deformation of the flow flange 9 separated from the valve body 1 is blocked by the expansion and contraction force of the bellows 8.

그러나, 이는 유동플랜지(9)로부터 가압링(4), 밸브몸체(1)의 일측 플랜지(2) 까지 일자(一字) 형태로 긴 볼트(7)와 너트(7)로 결합된 상태이고, 유동플랜지(9)와 가압링(4) 사이에 벨로우즈(8)가 연결 설치되어서 지반이 침하되거나 지진과 같은 진동이 발생하였을 때, 주름관 형태의 벨로우즈(8)가 밸브의 유체 흐름방향(중심선 "A"방향)으로는 신축에 대응하나, 중심선으로부터 경사방향(B)으로는 신축되지 못하여 지반침하와 같은 상황이 발생하는 경우에는 관로가 꺾이거나 파단 되는 문제를 지니고 있었다.However, this is in the state of being coupled with the long bolt 7 and the nut 7 in the shape of a letter from the flow flange 9 to the pressurizing ring 4, one flange 2 of the valve body 1, When the bellows 8 is connected between the flow flange 9 and the pressurizing ring 4 and the ground subsides or a vibration such as an earthquake occurs, a bellows 8 in the form of a bellows is formed in the fluid flow direction A "direction), but it was not stretched in the oblique direction (B) from the center line, and had a problem that the pipe was broken or broken when a situation such as subsidence occurred.

도 2, 3에 포함되는 구성 요소 중의 하나에 해당하는 밸브(10)를 스톱밸브에 속하는 글로브밸브를 도시하였으나, 단속밸브 및 체크밸브와 같이 유체의 흐름을 단속하거나, 유체의 흐름방향을 바꾸는데 사용되는 밸브는 모두 적용이 가능함을 밝혀둔다. Although the globe valve belonging to one of the constituent elements shown in Figs. 2 and 3 is shown as a stop valve, it is also possible to use the globe valve to control the flow of the fluid or change the flow direction of the fluid such as the intermittent valve and the check valve It is noted that all valves can be applied.

상기와 같이 구성되어 있는 본 발명의 작용관계를 도 2 내지 도 4를 참고하여 설명하면 다음과 같다.The operational relationship of the present invention constructed as described above will be described with reference to FIGS. 2 to 4. FIG.

도 2 및 도 3에 도시된 본 발명에 의한 신축밸브(60)는 공지된 바와 같이 유체관로(미도시)에 연결 설치되어 유체의 흐름을 단속하거나, 유체의 흐름방향을 바꾸는데 사용되는 것이며, 특히 지반침하나 지진과 같은 진동을 포함한 외력이 작용하는 유체관로에 적용 설치하는 것이 바람직한 것이다.The expansion valve 60 according to the present invention shown in FIGS. 2 and 3 is connected to a fluid conduit (not shown) to be used for interrupting the fluid flow or changing the flow direction of the fluid, It is preferable to apply the present invention to a fluid duct in which an external force including vibrations such as earthquakes or earthquakes acts.

상기 도 2, 3에 도시된 본 발명에 따른 신축밸브(60)를 조립하고자 하는 경우에는, 회전연결관(20)의 일측(도면상 우측)에 형성된 연결부(23)를 포함한 네크부(22)를 볼커버(30)의 나사연결부(31)측에서 구면접촉부(32) 후방측으로 관통시킨 상태에서 볼커버(30)의 나사연결부(31)를 밸브몸체(11)의 연결부(14)에 나사식으로 체결한다.2 and 3, the neck portion 22 including the connection portion 23 formed at one side (the right side in the drawing) of the rotary connection pipe 20 is provided with the neck portion 22, The screw connection portion 31 of the ball cover 30 is screwed into the connection portion 14 of the valve body 11 in a state where the screw connection portion 31 of the ball cover 30 is passed from the screw connection portion 31 side of the ball cover 30 to the rear side of the spherical contact portion 32 .

위와 같이 볼커버(30)를 밸브몸체(11)의 일측단부 외측에 형성된 연결부(14)에 체결하면, 볼커버(30)와 대면하는 반구면홈부(13)와 볼커버(30)의 구면접촉부(32)가 마주 대하면서 원형의 공간부가 형성되고, 그 원형의 공간부 내부에 회전연결관(20)의 볼부(21)가 삽입되어 공지된 볼조인트와 같이 원형의 공간부 내부에서 회전연결관(20)의 볼부(21)를 중심으로 회전이 자유로운 상태가 된다. As described above, when the ball cover 30 is fastened to the connecting portion 14 formed outside the one end of the valve body 11, the spherical contact portion 13 of the ball cover 30 and the hemispherical groove portion 13 facing the ball cover 30, And the ball portion 21 of the rotary coupling pipe 20 is inserted into the circular space portion so that the rotary coupling pipe 20 is inserted into the circular space portion like the known ball joint, The ball 20 can rotate freely around the ball 21.

이때, 상기 회전연결관(20)의 회전은 볼커버(30)의 후방의 개방된 내경보다 그에 대응되는 네크부(22)의 외경이 작은 만큼의 그렇게 차이가 나는 공간범위 안에서 회전되는 것은 물론이고, 방사상 아무 방향으로나 회전연결관(20)이 경사질 수 있게 되는 것이다.At this time, the rotation of the rotary connection pipe 20 is not limited to the rotation of the ball cover 30 in the range of the space where the outer diameter of the neck portion 22 corresponding to the inner diameter of the rear portion of the ball cover 30 is small , So that the rotary connector 20 can be tilted in any direction of the radial direction.

위와 같이 볼커버(30)의 후방으로 돌출된 회전연결관(20)의 후방단부에 신축연결관(40)의 전방연결부(41)를 연결하면 본 발명에 따른 신축밸브(60)의 조립이 완료되게 되고, 이렇게 조립된 신축밸브(60)를 유체관로(미도시)의 중간이나 단부에 설치하면 신축밸브(60)의 설치가 완료된다.When the front connection portion 41 of the expansion joint pipe 40 is connected to the rear end portion of the rotary connection pipe 20 protruding rearward of the ball cover 30 as described above, assembly of the expansion valve 60 according to the present invention is completed When the extensible valve 60 thus assembled is installed at the middle or end of the fluid conduit (not shown), the installation of the extensible valve 60 is completed.

이렇게 유체관로에 신축밸브(60)가 설치된 상태에서 지반침하나 지진과 같은 진동을 포함한 외력이 작용하게 되면, 볼조인트 형태로 연결 설치된 볼조인트관부(50)에서 회전연결관(20)이 외력이 작용하는 방향에 따라 각도가 구부러지게 되고, 그와 더불어 신축연결관(40)에 포함되는 주름관형태의 신축관체(43)도 외력이 작용하는 것에 따라 구부려지거나 길이방향으로 신축하게 된다.When an external force including vibrations such as earthquakes or earthquakes acts on the fluid pipe in the state where the expansion valve 60 is installed in the fluid pipe, an external force is applied to the rotary joint pipe 20 in the ball joint pipe portion 50, The expansion and contraction tube 43 in the form of a corrugated pipe included in the expansion joint tube 40 is also bent or stretched in the longitudinal direction as an external force acts.

위와 같이 지반침하나 지진과 같은 진동을 포함한 외력이 작용하는 경우에 유체관로에 설치된 볼조인트관부(50)와 신축연결관(40)이 외력이 작용하는 것에 따라 이중으로 구부러지고, 신축연결관(40)에서는 길이방향으로도 신축함에 따라 상기 외력에 유체관로와 신축밸브(60)가 연결된 부분의 손상을 최소화할 수 있게 되는 것이다.In the case where an external force including vibrations such as earthquakes is applied, the ball joint pipe portion 50 and the expansion joint pipe 40 installed in the fluid pipe are doubly bent as the external force acts on the pipe joint, 40, it is possible to minimize the damage of the portion where the fluid channel and the extensible valve 60 are connected to the external force by expanding and contracting in the longitudinal direction.

도 4에 도시된 볼조인트관부(50)도 도 2, 3에 도시된 일실시예와 동일하게 작용관계가 이루어지나, 조립과정은 다르므로 조립과정에 대해서만 설명하기로 한다.The ball joint pipe portion 50 shown in FIG. 4 operates in the same manner as in the embodiment shown in FIGS. 2 and 3. Since the assembling process is different, only the assembling process will be described.

즉, 도 4에 도시된 다른 실시예에 따른 볼조인트관부(50)를 조립하고자 하는 경우에는 원통관형태로 형성되며 후방측 외주연에 나사연결부(18)를 형성하고 전방측 내부에 걸림턱(17)을 형성한 출입관부(16)에 전방개스킷(15)을 삽입시키되, 내주면의 구면접촉부(15a)가 후방을 향하게 삽입시킨다.That is, when the ball joint pipe portion 50 according to another embodiment shown in FIG. 4 is to be assembled, a screw connection portion 18 is formed on the outer peripheral edge of the rear side, The front gasket 15 is inserted into the outlet tube portion 16 formed with the inner circumferential surface 17 and the spherical surface contact portion 15a of the inner circumferential surface is inserted rearward.

그 다음에 회전연결관(20)의 볼부(21)를 전방개스킷(15)측으로 삽입시켜 볼부(21)의 전방측 외주면이 전방개스킷(15)의 구면접촉부(15a)에 면접촉하게 삽입시키며, 그 뒤에는 전방측 내주면에 형성되는 구면접촉부(33a)가 볼부(21)의 후방외주연에 접촉하도록 후방개스킷(33)을 출입관부(16)의 내측으로 삽입시킨다.The ball portion 21 of the rotary connector 20 is inserted into the front gasket 15 so that the front outer circumferential surface of the ball portion 21 is inserted into the spherical contact portion 15a of the front gasket 15 in surface contact, The rear gasket 33 is inserted into the outlet tube portion 16 so that the spherical contact portion 33a formed on the inner circumferential surface on the front side comes into contact with the outer peripheral edge of the rear portion of the ball portion 21. [

그 뒤에 캡너트(19)를 출입관부(16)의 후방 외주연에 형성된 나사연결부(18)에 나사부가 체결되도록 캡너트(19)를 체결하면, 캡너트(19)의 내측에 형성된 돌출턱(19b)이 후방개스킷(33)의 후면을 전방측으로 밀어주면서 출입관부(16)의 나사연결부(18)에 캡너트(19)가 체결된다.The cap nut 19 is fastened to the screw connecting portion 18 formed on the outer circumference of the rear portion of the outlet pipe portion 16 so that the screw nut is fastened to the protruding jaw The cap nut 19 is fastened to the screw connecting portion 18 of the outlet tube portion 16 while pushing the rear surface of the rear gasket 33 forward.

위와 같이 캡너트(19)의 돌출턱(19b)을 밀어줄 때, 후방개스킷(33)의 구면접촉부(33a)가 볼부(21)를 전방으로 밀어주게 되고, 이렇게 전방으로 밀려들어가는 볼부(21)의 전방측 외주면이 전방개스킷(15)을 전방으로 밀어주면서 전방개스킷(15)의 전방이 밸브몸체(11)의 걸림턱(17)에 걸리면 캡너트(19)의 체결이 완료되게 된다.The spherical contact portion 33a of the rear gasket 33 pushes the ball portion 21 forward and the ball portion 21 pushed forward as described above is pushed forward by the spherical contact portion 33a of the rear gasket 33, Tightening of the cap nut 19 is completed when the front side outer circumferential surface of the front gasket 15 pushes forward the front gasket 15 and the front of the front gasket 15 is caught by the latching jaw 17 of the valve body 11. [

이때, 캡너트(19)의 중앙에는 연결부(23)를 포함한 네크부(22)가 관통되는 통공(19a)의 내경이 네크부(22)의 외경보다 크게 형성되고, 이 통공(19a)의 후방측 모서리 전둘레에는 경사부(19c)가 형성되어서 회전연결관(20)의 네크부(22)가 소정의 각도만큼 꺾인 각도에서 회전될 수 있게 된다.The inner diameter of the through hole 19a through which the neck portion 22 including the connection portion 23 passes is formed larger than the outer diameter of the neck portion 22 at the center of the cap nut 19, An inclined portion 19c is formed around the front edge of the side edge so that the neck portion 22 of the rotary connector 20 can be rotated at an angle bent by a predetermined angle.

여기서 회전연결관(20)의 네크부(22)가 소정의 각도만큼 꺾인 각도에서 회전될 수 있다는 것은, 지진이나 지반침하와 같은 외력이 작용했을 때, 회전연결관(20)의 볼부(21)가 전후방개스킷(15,33)의 구면접촉부(15a,33a)와 구면접촉해서 외력이 작용하는 것에 따라 볼부(21)의 중심을 기준으로 회전연결관(20)이 경사지게 기울여지는 것을 의미하는 것이다.The reason that the neck portion 22 of the rotary coupling pipe 20 can be rotated at an angle bent by a predetermined angle means that when the external force such as earthquake or ground subsidence acts on the ball portion 21 of the rotary connector 20, The spherical surface contact portions 15a and 33a of the front and rear gaskets 15 and 33 are in spherical contact with each other and an external force acts on the spherical contact portions 15a and 33a of the front and rear gaskets 15 and 33 so that the rotary connecting tube 20 is inclined with respect to the center of the ball portion 21.

도 4에 도시된 볼조인트관부(50)는 출입관부(16)의 후방외측에 캡너트(19)를 체결 설치함에 따라 캡너트(19)가 후방개스킷(33)을 전방으로 밀어주고, 후방개스킷(33)이 볼부(21)를 전방으로 밀며, 이렇게 밀리는 볼부(21)는 전방개스킷(15)을 전방으로 미는데, 밸브몸체(11)와 출입관부(16)의 경계부에는 전방개스킷(15)의 전방이 걸리는 걸림턱(17)에 걸려서 전후방개스킷(15,33)의 내주면에 형성된 각각의 구면접촉부(15a,33a)에 볼부(21)의 외부면이 면 지지되며, 회전연결관(20)의 볼부(21)를 중심으로 회전하거나, 또는 방사상 어느 방향으로나 구부려질 수 있게 되는 것이다.4, the cap nut 19 fastens the rear gasket 33 to the front as the cap nut 19 is fastened to the outside of the rear portion of the outlet tube portion 16, The ball body 21 pushes the front gasket 15 forward and the front gasket 15 is attached to the boundary between the valve body 11 and the outlet tube 16. [ The outer surface of the ball portion 21 is face-supported on the spherical contact portions 15a and 33a formed on the inner circumferential surface of the front and rear gaskets 15 and 33, It is possible to rotate about the ball portion 21 of the tapered portion 21 or to be bent in any direction in the radial direction.
