본 고안은 밸브에 관한 것으로서, 특히 통화로를 구성하는 케이블의 분기점이나 접속부위에 주로 설치되게 되며 열 수축관에 병행 설치되는 각각의 공기주입용 밸브와 압력점검용 밸브를 단일체로 집약 구축하여 설치하도록 함으로서 케이블 내부의 건조공기를 주입해 주는 작업 및 케이블내에 조성된 공기압의 압력치 점검작업을 병행실시할 수 있도록 한 열 수축관용 밸브에 관한 것이다.The present invention relates to a valve, and in particular, it is mainly installed at a branch point or a connection part of a cable constituting a communication path, and the air injection valve and the pressure check valve which are installed in parallel to a heat shrink tube are integrally built and installed. The present invention relates to a valve for a heat shrinkable tube, which is capable of simultaneously injecting dry air into a cable and checking a pressure value of air pressure formed in the cable.
일반적으로 유선통신에 소요되는 회선망은 지중 매설되는 경우가 많으며 수요자측에 가까워지면서 가공설치되는 바, 지중매설 케이블의 경우에는 각종 용도의 열수축관이 설치되고 필요시 공기주입케이블을 시공하여 건조공기를 지속적으로 불어 넣어줌으로서 케이블내의 습기침투를 방지하고 있다.In general, the line network required for wired communication is often buried underground, and is processed and installed close to the consumer's side. In the case of underground buried cables, heat shrink pipes for various purposes are installed and, if necessary, air drying cables are installed to dry air. It is continuously blown to prevent moisture penetration into the cable.
케이블내의 습기침투는 회선망의 오동작을 유발하게됨에 따라 공기주입케이블을 설치한 자중매설 회선에서는 공기 주입과 그 공기압검출을 위한 밸브가 열수축관상에 필수적으로 설치되게 된다.Moisture penetration in the cable causes malfunction of the circuit network. Therefore, in the self-loading circuit in which the air injection cable is installed, a valve for air injection and air pressure detection is essentially installed on the heat shrink pipe.
이 공기주입을 위한 밸브는 통상 전화국 부근에 설치되어 공기 주입장치로 부터 건조공기를 받아 열수축관을 통하여 공기주입케이블에 공기주입을 유도하게 되고 필요시는 공기주입라인을 연장하여 증설하기도 한다.The valve for air injection is normally installed near the telephone station to receive dry air from the air injection device to induce air injection into the air injection cable through the heat-shrink tube and to extend the air injection line if necessary.
한편 공기압의 검출을 위하여 설치하는 밸브는 통상적으로 직선 구간에서는 약 500m 간격으로 설치하거나 또는 선로의 분기점 등에 시공하고 있다. 이 공기압은 대랴 공기주입 초단에서는 약 10PSI, 종단에서는 약4PSI정도를 유지케 하는데, 종래의 공기주입밸브는 엘보우(elbow)형태로 이루어져 단순히 공기 주입만을 행할 수 있게 되는가 하면, 공기압 검출밸브는, 열수축관에 베이스확장 결합되도록 된 하부체에, 기밀유지 목적인 상광하협의 테이퍼나사부가 형성되어 역지변이 나사결합된 상부체와 조립결합된 상태인 관계로 온도변화에 따른 결합부 파열을 초래하게 된다.On the other hand, valves provided for the detection of air pressure are typically installed at intervals of about 500 m in a straight section or are installed at branch points of a track. This air pressure is maintained at about 10 PSI at the beginning of the air injection and about 4 PSI at the end. However, the conventional air injection valve has an elbow shape, and only the air injection can be performed. The tapered screw portion of the upper and lower straits for airtightness is formed on the lower body which is to be extended to the base and is connected to the upper body with the reverse displacement coupled to the screwed upper part.
또한 공기주입밸브와 공기압 검출밸브의 분리구성은 열수축관의 밸브설치위치를 2개소로 가공할 수 밖에 없도록 하여 기밀유지를 어렵게 만들고 설치공정이 번잡하게 되는 동시에 소요밸브의 증가라는 문제점을 유발하는 실정인 것이다.In addition, the separate configuration of the air injection valve and the air pressure detection valve makes it difficult to maintain the airtightness by making the valve installation position of the heat shrinkage pipe two places, and the installation process is complicated and at the same time, it causes the problem of an increase in required valves. It is
한편 본 출원인이 이를 개선하고자 출원한 선원(실용신안등록출원 제89-14273호)에선 상기 종래의 문제점을 해결한 일체형성된 T형의 밸브를 안출하였던 바 이 선윈의 밸브에 있어서 열수축관 내에 형성된 공기압을 검출하고자 하는 경우 작업자가 일일히 이격설치된 밸브에 나아가서 수작업을 행하여야 하는 번거로움은 여전히 남아 있는 실정이다.On the other hand, the crew (Application Model Registration Application No. 89-14273) filed by the present applicant to improve this has come up with an integrally formed T-type valve that solves the conventional problems. If you want to detect the situation is still a hassle that the worker has to go to the valve installed by hand to perform the manual work.
그러나 최근들어 주면기술의 발전으로 말미암아 열수축과내에 공기압을 중앙에서 검지할 수 있는 정도에 이르게 되어 상기 수작업에 의한 공기압 검출방식과 병용되고 있어 열수축관으로부터 중앙제어욱(전화국등)으로 회선을 구성하기에 이르렀다.However, in recent years, due to the development of technology, it has reached the level where the air pressure in the heat shrinkage section can be detected centrally, and it is used together with the air pressure detection method by the above-mentioned manual work to form a line from the heat shrink pipe to the central control station (telephone station, etc.). Reached.
따라서 열수축관내에서 검출을 위한 도선을 분기인출하여 중앙 제어국으로의 회선망을 구성함에 있어서 종래의 밸브와 본출원인의 선원 고안은 부적합하다.Therefore, in designing a circuit network to the central control station by branching out the lead wire for detection in the heat shrinkage pipe, the conventional valve and the original source design of the present applicant are not suitable.
그러므로 본 고안은 상기 종래의 제반문제점을 해소하고자 안출된 것으로서 다음과 같은 목적을 갖는다.Therefore, the present invention has been made to solve the above-mentioned conventional problems and has the following object.
첫째, 본 고안은 열수축관용 공기주입밸브를 형성에 있어서 열수축관에서 분기한 도선을 인출할 수 있도록 수직관통된 통공을 형성하여 중앙제어국으로의 회선망 구멍을 가능하게 이뤄진 밸브를 제공하는데 있다.First, the present invention is to provide a valve made of a line through the hole to the central control station by forming a vertical through-hole to draw the lead branch branched from the heat shrink tube in forming the air injection valve for the heat shrink tube.
둘째, 본 고안은 열수축관용 공기주입 밸브를 형성함에 있어서 건조공기 주입과 케이블내의 공기압검출이 가능하도록 된 밸브를 제공하는데 있다.Second, the present invention is to provide a valve that is capable of injecting dry air and detecting the air pressure in the cable in forming the air injection valve for the heat shrink pipe.

다음은 상술된 바와 같은 구성을 갖는 본 고안의 효과를 좀더 상세하게 살펴보고자 한다.Next will be described in more detail the effect of the present invention having the configuration as described above.
제1도 내지 제3도에 있어서 통상적으로 공기주입케이블을 시공하는 회선망에는 공기주입을 위한 본 고안의 열수축관용 밸브체(1)가 통상의 I형 밸브(22)상에 설치시공된다.1 to 3, a heat shrink pipe valve body 1 of the present invention for air injection is installed on a conventional I-type valve 22 in a circuit network in which an air injection cable is normally constructed.
본 고안의 설치를 살펴보면 I형 밸브(22)에 나사결합되고 공기주입용 튜브(23)를 환형돌기(17)에 끼워넣어 압압너트(3)로서 체결하게 되면 환형돌기(17)상에 튜브(23)는 긴밀하게 압압되어 기밀을 유지하게 된다.Looking at the installation of the present invention is screwed to the I-type valve 22 and the air injection tube 23 is inserted into the annular projection (17) and tightened as a pressing nut (3) tube (on the annular projection 17) 23 is tightly pressed to maintain confidentiality.
한편 공기압 검출을 위하여 중앙제어국으로 회선을 구성하는 경우에 있어서는 열수축관 내측으로부터 분기된 도선(21)을 관통공(4)을 통하여 인출하고 공기유출방지를 위하여 튜브(24)를 상기 설명한 바와 같이 환형돌기(13)에 압지 체결하여 설치하게 된다.On the other hand, in the case of forming a line to the central control station for detecting the air pressure, the lead wire 21 branched from the inside of the heat shrinkage tube is drawn out through the through hole 4 and the tube 24 is prevented as described above to prevent air leakage. It is installed by press-fitting to the annular projection (13).
그러나 중앙제어국에서의 공기압 검출이 필요치 않는 경우에 있어서는 역지변(미도시됨)을 나사부(12)에 나합하고 외주의 나사부(11)에 캡(10)을 씌워 설치하면 된다.However, in the case where the air pressure detection at the central control station is not necessary, a reverse displacement (not shown) may be screwed on the threaded portion 12 and the cap 10 may be provided on the threaded portion 11 of the outer circumference.
이상에서 상술한 바와 같은 본 고안은 공기주입 케이블내의 공기압을 검출하기 위한 중앙제어국으로의 도선의 연결을 위한 인출공을 수직관통공으로 형성하여 인출이 용이하게 되고 이로서 공기압 검출이 용이하게 되는 효과를 갖는 매우 유용한 고안인 것이다.As described above, the present invention has the effect that the drawing hole for connecting the conductor to the central control station for detecting the air pressure in the air injection cable is formed through the vertical through-hole, so that the drawing is easy and thus the air pressure is easily detected. It is a very useful design.
