Description

가스계량기의 유니온 너트의 봉인구조{Sealing structure for nut}Sealing structure for nut nut of gas meter

본 발명은 가스계량기의 봉인에 관한 것으로, 더욱 상세하게는 납봉인과 봉인지 봉인을 동시에 수행할 수 있는 가스계량기의 유니온 봉인구조에 관한 것이다.The present invention relates to a seal of a gas meter, and more particularly, to a union seal structure of a gas meter capable of simultaneously performing a lead seal and a seal seal.

현재 아파트 단지나 대단위 복합건물의 가스 사용량 검침을 위한 계량기는 통상 각 가정의 내부에 설치되고 있는 실정이며, 일부의 사용자가 계량기와 가스관을 연결하는 가스 밸브를 고정하는 유니온을 임의로 조작하여 별도의 배관을 연결하여 무단으로 사용하고 있는 경우가 종종 있다.Currently, meter for metering gas usage of apartment complex or large-scale complex is usually installed inside each home, and some users can operate a union to fix gas valve connecting meter and gas pipe. Is often used without permission.

따라서 배관 각부의 연결이 완벽하지 못하여 누출된 가스로 인한 사고가 발생하는 폐단과 가스공급자의 피해가 속출하고 있다.Therefore, the connection of each part of the pipe is not perfect, the damage caused by the leaked gas and accidents are continuously occurring.

이때, 가스사고의 경우 누출된 가스로 인한 사고 발생시 그 책임을 가스 공급자에게 전가하므로 완벽한 시공을 하였음에도 불구하고 사용자의 과실에 의하여 공급업자가 그 피해를 입게 된다.In this case, in the case of a gas accident, the responsibility is passed to the gas supplier when an accident due to leaked gas occurs, so the supplier is injured by the user's fault despite the perfect construction.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 유니온 너트의 외면을 특별 가공하여 봉인줄에 의해 계량기 본체와 봉인을 하며, 유니온 너트의 외면에 봉인지를 부착하여 이중 봉인을 할 수 있는 가스계량기의 유니온 봉인구조를 제공하는데 있다.The present invention has been made in order to solve the above problems, the outer surface of the union nut is specially processed to seal the meter body by the sealing line, the gas can be double sealed by attaching a seal on the outer surface of the union nut It is to provide the union seal structure of the meter.

상기와 같은 과제를 해결하기 위해 본 발명은,The present invention to solve the above problems,

도시가스를 공급받기 위해 공급관과 계량기를 결합시켜주는 유니온의 봉인구조에 있어서,In the sealing structure of the union that combines the supply pipe and the meter to receive the city gas,

유니온 너트의 팔각면중 이웃하지 않은 네면에는 돌출링이 일체로 형성되면서 돌출링에는 각각 상부 봉인홀이 형성되고, 계량기 본체의 상부측에는 상부 봉인홀과 대향되도록 하부 봉인홀이 형성된 연장부가 일체로 형성되어, 상부 봉인홀과 하부 봉인홀로 봉인줄을 삽입하여 봉인하며, 유니온 너트의 돌출링 사이 부착면상에는 계량기 본체의 유입관측으로 연장되는 봉인지를 부착하여 봉인하되, 유입관은 유니온 너트의 두께와 대응되도록 볼록부가 형성됨을 특징으로 하는 가스계량기의 유니온 봉인구조를 제공한다.Protruding rings are integrally formed on four non-neighbored surfaces of the union nut, and upper sealing holes are formed on the protruding rings, respectively, and an extension portion formed with a lower sealing hole is integrally formed on the upper side of the meter body so as to face the upper sealing hole. The sealing line is inserted into the upper sealing hole and the lower sealing hole to seal the seal, and on the attachment surface between the union rings of the union nut, a seal extending to the inlet pipe side of the meter body is sealed and the inlet pipe corresponds to the thickness of the union nut. It provides a union sealing structure of the gas meter, characterized in that the convex portion is formed as possible.

이때, 하부 봉인홀은 연장부의 가운데와 양옆으로 각각 형성됨이 바람직하다.At this time, the lower sealing hole is preferably formed in the middle and both sides of the extension.

전술한 바와 같이 본 발명에 따른 봉인구조는 유니온과 계량기 본체에 봉인줄이 삽입되는 봉인홀을 형상하면서 봉인지를 함께 부착시킬 수 있도록 하여 봉인해체의 위험으로부터 보호받을 수 있는 잇점이 있다.As described above, the sealing structure according to the present invention has the advantage of being able to attach the seals together while forming a seal hole into which the seal line is inserted into the union and the meter body, thereby being protected from the risk of dismantling the seal.

이하, 첨부된 도면들을 참조하여 본 발명의 바람직한 실시예에 따른 가스계량기의 유니온 봉인구조를 설명한다.Hereinafter, with reference to the accompanying drawings will be described a union seal structure of the gas meter in accordance with a preferred embodiment of the present invention.

도 1은 본 발명에 따른 가스계량기의 유니온 봉인구조를 나타낸 사시도이며, 그리고 도 2는 도 1의 유니온 부분을 확대한 사시도이다.1 is a perspective view showing a union sealing structure of the gas meter according to the present invention, and Figure 2 is an enlarged perspective view of the union portion of FIG.

도 1 및 도 2를 참고하면, 본 발명에 따른 봉인구조는 계량기 본체(10)와 연결되는 공급관(20)과의 사이를 결합시켜주는 유니온 너트(30)을 봉인줄(40)로 봉인하는 구조와, 유니온 너트(30)의 외면 및 계량기 본체(10)에 함께 부착시키는 봉인지(50)에 의한 봉인으로 이루어진다.1 and 2, the sealing structure according to the present invention is a structure for sealing the union nut 30 for coupling between the supply pipe 20 is connected to the meter body 10 with a sealing line 40 And a seal by a seal 50 which is attached together to the outer surface of the union nut 30 and the meter body 10.

이러한 봉인구조를 갖기 위해 유니온 너트(30)의 외면상에는 돌출링(31)이 형성된다.In order to have such a sealing structure, a protruding ring 31 is formed on the outer surface of the union nut 30.

유니온 너트(30)는 팔각형으로 된 너트로서, 기존에는 이러한 너트를 봉인하기 위해 너트의 모서리부에 봉인홀을 뚫어 사용되기도 하였다.Union nut 30 is an octagonal nut, which was previously used to seal the hole in the corner of the nut to seal the nut.

그러나 본 발명에서는 유니온 너트(30)의 외면상에 돌출링(31)을 형성하되, 팔각형 중에서 서로 이웃하지 않게 하나 건너뛰는 네면에만 돌출링(31)을 형성하고, 이 돌출링(31)에 상부 봉인홀(32)을 뚫어 형성하게 된다. 그리고 나머지 네면은 민자형태가 유지되도록 부착면(33)이 형성된다.However, in the present invention, but protruding ring 31 is formed on the outer surface of the union nut 30, the protruding ring 31 is formed only on the four sides of the octagon not to be adjacent to each other, and the upper part on the protruding ring 31 The sealing hole 32 is formed by drilling. And the other four sides are formed with the attachment surface 33 to maintain the civil shape.

다음은 상부 봉인홀(32)과 대향되도록 계량기 본체(10)에도 하부 봉인홀(12)을 형성하여야 한다.Next, the lower sealing hole 12 should be formed in the meter body 10 so as to face the upper sealing hole 32.

따라서 계량기 본체(10)의 상부측에는 돌출링(31)과 대향되는 연장부(11)를 일체로 형성하고, 이 연장부(11)에 하부 봉인홀(12)을 상하로 관통하여 형성한다.Therefore, the upper part of the meter body 10 is integrally formed with an extension part 11 facing the protruding ring 31, and the lower sealing hole 12 penetrates the extension part 11 up and down.

이때, 하부 봉인홀(12)은 가운데에 하나와 양쪽에 각각 하나씩을 형성함이 바람직하다.At this time, the lower sealing hole 12 is preferably formed in each one and one in the center.

이와 같이 하부 봉인홀(12)을 여러개 형성시키는 이유는 상부 봉인홀(32)은 유니온 너트(30)의 체결에 의해 위치가 변하기 때문에 네 개의 돌출링(31)에 각각 형성하였다. 따라서 어느 방향으로 상부 봉인홀(32)이 위치할지 예측할 수 없으므로 하부 봉인홀(12)도 여러 방향에 각각 형성하여 적절히 대응하도록 한 것이다.The reason for forming a plurality of lower sealing holes 12 as described above is that the upper sealing holes 32 are formed in the four protruding rings 31 because the position is changed by the fastening of the union nut (30). Therefore, since it is impossible to predict in which direction the upper sealing hole 32 will be located, the lower sealing hole 12 is also formed in various directions to correspond appropriately.

이와 같이 형성된 상부 봉인홀(32)과 하부 봉인홀(12)에 봉인줄(40)을 삽입하여 봉인납(41)을 결합한후, 와인딩하여 봉인을 완성한다.The sealing line 40 is inserted into the sealing line 40 by inserting the sealing line 40 into the upper sealing hole 32 and the lower sealing hole 12 formed as described above, and then winding to complete the sealing.

다음으로 봉인지(50)에 의한 봉인은 유니온 너트(30)에서부터 계량기 본체(10)까지 봉인지(50)가 걸쳐지도록 하여 유니온 너트(30)를 돌릴 경우 봉인지가 찢어지도록 하는 봉인방법이다.Next, the sealing by the seal 50 is a sealing method so that the seal is torn when turning the union nut 30 so that the seal 50 extends from the union nut 30 to the meter body 10.

그러나 유니온 너트(30)를 계량기 본체(10)의 유입관(15)에 체결될 때에 유니온 너트(30)의 봉인지 부착면(33) 두께만큼 방사상으로 돌출되어 있다. 따라서 유입관(15)에도 유니온 너트(30)의 봉인지 부착면(33)과 같은 두께를 갖도록 볼록부(16)를 더 형성할 필요가 있게 된다.However, when the union nut 30 is fastened to the inlet pipe 15 of the meter body 10, the union nut 30 protrudes radially by the thickness of the sealing surface 33 of the union nut 30. Therefore, it is necessary to further form the convex part 16 in the inflow pipe 15 so that it may have the same thickness as the sealing surface attachment surface 33 of the union nut 30. FIG.

이와 같이 형성된 볼록부(16)와 유니온 너트(30)의 부착면(33)에 봉인지(50) 를 양측이 걸쳐지게 부착하여 이중 봉인을 하게 된다.Both sides of the seal 50 are attached to the convex portion 16 and the attachment surface 33 of the union nut 30 thus formed so as to double seal.

상기에서는 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 해당기술분야의 숙련된 당업자는 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.Although described above with reference to a preferred embodiment of the present invention, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims You will understand.

도 1은 본 발명에 따른 가스계량기의 유니온 봉인구조를 나타낸 사시도고,1 is a perspective view showing a union sealing structure of the gas meter according to the present invention,

도 2는 도 1의 유니온 부분을 확대하여 나타낸 사시도이다.FIG. 2 is an enlarged perspective view of the union part of FIG. 1. FIG.
