Description

이동플랜지를 갖는 밸브{Valve}Valve with moving flange {Valve}

본 발명은 밸브에 관한 것으로, 더욱 상게하게는 이동플랜지에 의한 가변적 설치관계로서, 불필요한 관로의 절단 및 그 절단부위 재 연결을 위한 용접작업 등을 배제되게 하여, 일련의 밸브 설치 및 교환작업 관계를 보다 편리하고, 용이하게 행할 수 있도록 한 이동플랜지를 갖는 밸브에 관한 것이다. The present invention relates to a valve, and more particularly, a variable installation relationship by a movable flange, which eliminates unnecessary pipe cutting and welding work for reconnecting the cut portion, thereby eliminating a series of valve installation and replacement work relationships. The present invention relates to a valve having a movable flange which can be more conveniently and easily performed.

일반적으로 밸브라 함은 높은 기밀성을 요하는 시설물, 다시 말해, 물, 기름, 가스 등이 유동되는 배관라인에 설치된 상태로서, 유체 및 기체의 흐름을 안정적으로 유도 또는 차단되게 하는 장치이다.In general, a valve is a device installed in a pipe line through which water, oil, gas, etc., which require high airtightness, flows, and is a device that stably induces or blocks the flow of fluid and gas.

이에, 상기와 같은 용도로 사용되는 종래 밸브의 구성 및 설치관계를 간략하게 살펴보면;Thus, briefly look at the configuration and installation relationship of the conventional valve used for the above purposes;

이는, 도 1로 도시된 바와 같은 구조로서, 좌,우 양측 단부에 상호 대칭되는 한쌍의 설치플랜지(101)가 일체로 구비되고, 그 내부에 유동통로(102)가 형성된 원통형 구조의 밸브본체(10)를 기초 구성으로 하여; This is a structure as shown in Figure 1, a pair of mounting flanges 101 which are mutually symmetrical to both left and right ends are integrally provided, the valve body of the cylindrical structure formed with a flow passage 102 therein ( 10) as a basic configuration;

상기, 유동통로(102) 내측 중앙부에, 그 유동통로(102)의 개,폐를 단속되게 하는, 회동구조의 밸브디스크(20)를 설치토록 하여, 이루어진다. The valve disc 20 of the rotational structure which intermittently opens and closes the flow path 102 is provided in the center part inside the flow path 102, and it is provided.

아울러, 이와 같은, 종래 밸브를, 배관라인에 설치함에 있어서는, 도 1로 도시된 바와 같이, 설치하고자 하는 배관라인에 있어, 임의의 위치, 즉, 배관라인을 이루는, 유입관로(30)와, 배출관로(40) 사이에, 소정길이의 밸브설치공간을 확보되게 한 후, 그 설치공간부에 밸브본체(10)를 삽입하고, 이어, 설치플랜지(101) 밀착에 따른 볼트(도시생략) 체결관계로서, 일련의 설치관계를 갖게 하는 것이다.In addition, in the installation of such a conventional valve in the piping line, as shown in Figure 1, in the piping line to be installed, the inlet pipe 30, which constitutes an arbitrary position, that is, the piping line, After the valve installation space of a predetermined length is secured between the discharge pipe passages 40, the valve body 10 is inserted into the installation space portion, and then a bolt (not shown) is tightened according to the installation flange 101. As a relationship, it is to have a series of installation relationships.

하지만, 전술한 바와 같은, 종래의 밸브는, 지속적 사용에 따른 부품의 마모, 고장 및 기타 이상 발생으로, 교체 및 수리작업을 요할 경우, 그 설치된 배관라인으로 부터, 밸브를 해체 한 후, 새로운 밸브로 교환하거나, 혹은, 수리하여, 재 장착하는 과정을 행하게 되는 것이었던바;However, the conventional valve, as described above, is a new valve after disassembling the valve from the installed piping line when replacement and repair work are required due to the wear, failure and other abnormalities of parts due to continuous use. To replace, repair, or refit;

따라서, 상기와 같이, 배관라인으로 부터, 밸브를 분리하여, 교환작업을 행할 경우, 그 교환되는 종래의 밸브는 가변적 길이조절이 불가능한 구조, 즉, 밸브본체와, 좌,우 한쌍의 설치플랜지가 도 1로 도시된 바와 같이, 일체화된 단일몸체 구성을 취함에 따라, 그 설치부위에 규격차이(밸브의 설치공간길이)를 발생시키며, 플랜지 결합부위를 이격되게 함으로 인해, 밸브와, 배관라인 연결부위의 기밀성을 상실되게 하는 문제점을 주는 것이었다.Therefore, as described above, when the valve is removed from the piping line and the replacement operation is performed, the conventional valve to be replaced has a structure in which variable length adjustment is impossible, that is, a valve body and a pair of left and right mounting flanges. As shown in FIG. 1, as a unitary single-body configuration is taken, a standard difference (installation space length of the valve) is generated at its installation portion, and the flange coupling portion is spaced apart, thereby connecting the valve and the piping line. It was to give a problem to lose the confidentiality of the site.

한편, 또 다르게, 전술한 종래의 밸브는, 그 교환 설치과정에 있어, 배관라인 연결부위의 기밀성 상실을 보완하기 위한 방안으로서, 도 1로 도시된 바와 같이, 배관라인의 일측 관로를 절단하고, 그 절단된 관로를 이용, 밸브설치공간부의 길이를 임의적으로 조절되게 하여, 밸브를 안정적으로 밀착되게 하는, 교환, 설치방법을 이용하고 있는 실정이기는 하나, 이와 같은, 방법은 관로의 절단작업은 물 론, 그 절단된 관로를 재 접합하기 위하여, 도 1로 도시된 바와 같이, 별도의 연결부재(50) 이용 및 용접가공 등의 방법을 실시해야 하는 것으로, 이에, 일련의 밸브 교환 설치작업을 매우 난해하고, 번거롭게 하는 문제점을 주는 것이었으며;On the other hand, another conventional valve described above, in the exchange installation process, as a way to compensate for the loss of airtightness of the pipe line connection portion, as shown in Figure 1, by cutting off one side of the pipe line, Although the situation is using an exchange and installation method in which the length of the valve installation space is arbitrarily adjusted by using the cut pipe, and the valve is securely in close contact, the method of cutting the pipe is water In order to rejoin the cut pipe, as shown in FIG. 1, a separate connection member 50 and a welding process should be performed. To be difficult and cumbersome;

특히, 절단 및 재 접합되는 배관라인의 결함 발생으로 인해, 고압의 유체 및 기체가, 상기 배관라인을 흐름될 경우, 그 흐름 압력에 적절히 대응하지 못한체, 배관라인의 절단 연결부위가 파열되는 등, 상당한 내구성 저하의 문제점을 상존되게 하는 것이었다. In particular, due to the occurrence of defects in the pipe line to be cut and rejoined, when the high-pressure fluid and gas flows through the pipe line, the cutting connection part of the pipe line is ruptured, which does not properly correspond to the flow pressure. The problem of significant durability deterioration has been to exist.

따라서, 본 발명은 설치,구조상의 폐단을 갖는 종래 밸브의 제반적인 문제점을 해결하고자 창안된 것으로;Accordingly, the present invention has been made to solve the general problems of the conventional valve having a closed end of the installation, structure;
