Abstract

본 고안은 플렌지 타잎의 가스밸브안전장치에 관한 것으로, 보다 상세하게는 밸브동체가 외부의 요인(예를 들면 화재 또는 외기의 온도가 지나치게 높을때 등등…)에 의해 열을 크게 받더라도 가스누출이 발생되지 못하도록 구성하여 안전성을 극대화시킨 것이다.The present invention relates to a gas valve safety device of a flange type, more specifically, even if the valve body receives a large amount of heat due to an external factor (for example, when the temperature of the fire or the outside air is too high, etc.), a gas leak occurs. It is configured not to maximize safety.

주지된 바와같이 가스밸브는 가스를 공급및 차단시키기 위해사용하는 밸브이고, 플렌지 타잎의 밸브는 주로 많은량의 가스를 공급이송시키는 가스배관에 설치되는 밸브이다.As is well known, the gas valve is a valve used to supply and shut off gas, and the valve of the flange type is a valve installed in a gas pipe mainly supplying a large amount of gas.

또한 상기 밸브는 주로 주물제품으로 형성되어 있고 내부에는 관통구멍을 가진 볼이 내장설치되면, 상기 볼에는 상단에 밸브개폐레버와 외부하측부에 오링을 설치한 밸브스템이 연결설치되고, 동체와 상기 밸브스템사이에 고무패킹 및 패킹이 설치되어 가스의 유출을 예방할수 있게끔 구성되어 있다.In addition, the valve is mainly formed of a cast product and when a ball having a through hole is installed inside, the ball valve opening and closing valve at the top and the valve stem provided with an O-ring at the outer lower side is installed, the body and the Rubber packing and packing are installed between valve stems to prevent outflow of gas.

그러나 전술한 종래 플렌지 타잎의 가스밸브는 화재등이 발생하여 많은 열이 작용하게 되면, 가스가 누출되어 폭발및 대형사고로 연결될 염려가 매우큰데, 그 이유는 기밀유지를 고무패킹에만 의존하기 때문이다.However, when the gas valve of the conventional flange type is fired and a lot of heat is applied, there is a high possibility that the gas will leak and lead to an explosion and a large accident because the airtightness depends only on the rubber packing. .

따라서 본 고안은 동체의 패킹안착부에 동재질로 형성한 안전링을 삽입설치하여 화재등이 발생하여 밸브가 열을 받게되면 동으로 된 안전링이 열에 의해 팽창하여 가스의 누출염려를 사전에 예방함으로써 가스누출로 인한 안전사고 및 대형사고, 참사등을 사전에 예방할수 있게 하려는 것이다.Therefore, the present invention inserts and installs a safety ring formed of the same material on the packing seat of the fuselage. If a fire occurs and the valve receives heat, the safety ring made of copper expands by heat to prevent gas leakage in advance. By doing so, it is possible to prevent safety accidents, large accidents, and disasters caused by gas leakage in advance.

Description

플렌지 타잎 가스밸브의 안전장치{Plant type gasvalve of safety device}Plant type gasvalve of safety device

본 고안은 플렌지 타잎 가스밸브의 안전장치에 관한 것으로, 좀 더 구체적으로는 화재나 기타 외부요인(즉, 지진이나 폭발등등…)에 의해 가스관및 가스밸브가 심하게 열을 받더라도 가스누출 염려가 없게 하기 위한 것이다.The present invention relates to the safety device of the flange type gas valve, and more specifically, so that the gas pipe and the gas valve are severely heated by a fire or other external factors (ie, earthquake or explosion, etc.) so that there is no fear of gas leakage. It is for.

주지된 바와같이 가스밸브는 가스를 공급및 차단시키는 장치를 말하며, 가스밸브중 플랜지 타잎의 가스밸브는 통상 중용량이상의 가스가 공급순환되는 가스배관에 설치사용된다.As is well known, the gas valve refers to a device for supplying and shutting off gas, and the gas valve of the flange type of the gas valve is usually used for installation in a gas pipe in which a gas of more than a medium capacity is supplied and circulated.

또한 상기한 가스밸브는 동체가 주물제품으로 형성되어 있고 내부에는 관통구멍이 형성된 볼이 내장설치되며, 상기 볼에는 상단에 밸브개폐레버와 외부하측부에 오링을 설치한 스템이 연결설치되고, 동체와 상기 스템사이에 고무패킹및 패킹이 설치되어 가스의 유출을 예방할수 있게끔 구성되어 있다.In addition, the gas valve is formed of a cast body of the body and the ball is provided with a through hole formed inside, the ball is connected to the valve opening and closing lever at the top and the stem is installed in the outer lower side, the body is installed Rubber packing and packing is installed between the stem and the stem is configured to prevent the outflow of gas.

그러나 전술한 종래 플렌지 타잎의 가스밸브는 화재등이 작용하여 많은 열이 작용하게되면 가스가 누출되어 폭발및 대형사고의 염려가 매우 크다.However, the above-described conventional flange type gas valve has a great risk of explosion and large accidents when the gas leaks when a lot of heat is applied due to a fire or the like.

즉, 종래의 가스밸브는 기밀유지를 고무패킹에만 의존하기 때문에 화재등으로 인하여 패킹이 열을 받아 변형되면 가스누출이 필연적으로 발생할수 밖에 없기 때문이다.That is, since the conventional gas valve depends only on the rubber packing to maintain airtightness, if the packing is deformed due to the heat due to a fire or the like, gas leakage will inevitably occur.

따라서 가스관 또 가스밸브 주위에 화재가 발생하였을때 가스누출을 차단 할수 있는 장치의 개발이 시급하였던 것이다.Therefore, it was urgent to develop a device that can block gas leakage when a fire occurs around a gas pipe or a gas valve.

본 고안은 전술한 종래의 제반문제점을 감안하여 안출된 것으로 특히 동체의 패킹 안착부에 연신률이 양호한 동재질의 안전링을 삽입설치하여 화재등이 발생하여 밸브가 열을 발생하게 되면 동으로 된 안전링이 열에 의해 팽창하여 가스의 누출염려를 사전에 예방함으로써, 가스누출로 인한 안전사고 및 대형사고, 참사등을 사전에 에방할수 있는 안전장치를 제공하는데 그 목적이 있는 것이다.The present invention has been devised in view of the above-mentioned conventional problems. In particular, a safety ring made of copper material having a good elongation is inserted into the packing seating part of the fuselage, and when the valve generates heat due to a fire, the safety of copper The ring is inflated by heat to prevent the leakage of gas in advance, the purpose is to provide a safety device that can prevent the safety accidents, large accidents, disasters, etc. due to gas leakage in advance.

도 1은 본 고안의 단면도1 is a cross-sectional view of the present invention

동체(1)양측에 플렌지(2)(2')가 형성되고, 내부에 볼밸브(3)가 내장되어 밸브스템(4)에 의해 레버(5)와 연결구성되며, 상기 밸브스템(4)이 관통설치되는 동체(1)에패킹(6)이 설치된 통상의 플렌지 타잎 가스밸브(20)에 있어서,Flange (2) (2 ') is formed on both sides of the body (1), the ball valve (3) is built therein and connected to the lever (5) by the valve stem (4), the valve stem (4) To this fuselage In the normal flange type gas valve 20, the packing 6 is provided,

밸브 스템(4)이 관통설치되는 동체(1)의 패킹 안착부(7) 하부에 단차진 또하나의 안전링 안착부(8)를 형성하여 이곳에 동 또는 동합금재질로 된 안전링(9)을 삽입 안착시킴으로서, 화재가 발생하였을때 열이 가스밸브에 작용하더라도, 안전링(9)이 열에 의해 팽창하게 됨으로서 가스의 누출이 예방되게 한 것이다.A safety ring (9) made of copper or copper alloy is formed here by forming another safety ring seating portion (8) stepped below the packing seating portion (7) of the body (1) through which the valve stem (4) is installed. By inserting and seating, even if heat acts on the gas valve when a fire occurs, the safety ring (9) is expanded by the heat to prevent the leakage of gas.

미설명부호 10은 씨트링이고, 11은 스톱퍼, 12는 기밀유지용 오링, 13은 리테이너, 14는 오링이다.Reference numeral 10 is a seat ring, 11 is a stopper, 12 is an airtight O-ring, 13 is a retainer, and 14 is an O-ring.

이와같이 구성된 본 고안은 볼 밸브(3)와 연결설치되는 밸브스템(4)과 동체(1) 사이에 통상의형 패킹외에 동또는 동합금 재질의 안전링을 설치하였음으로 화재등으로 인하여 밸브가 가열되더라도 안전링(9)이 팽창하여 가스누출을 차단하게 된다.The present invention configured as described above is generally used between the valve stem 4 and the fuselage 1 which are connected to the ball valve 3. Since the safety ring of copper or copper alloy is installed in addition to the mold packing, the safety ring 9 expands to block gas leakage even when the valve is heated due to a fire.

따라서 안전성이 매우 높아 사고예방에 기여할수 있게 된다.Therefore, safety is very high, which can contribute to accident prevention.

이상 설명한 바와같이 본 고안은 플렌지 타잎 가스밸브에 있어서,As described above, the present invention provides a flange type gas valve.

밸브스템(4)과 동체(1)사이에 통상''형패킹외에 동 또는 동합금으로 된 안전링(9)을 삽입 안착시킴으로서 화재발생시 밸브가 열을 받을때 안전링(9)이 팽창하여 가스누출을 차단 및 예방함으로써 가스사고 및 대형사고를 예방할수 있게되는 매우 유용한 고안인 것이다.Between the valve stem (4) and the fuselage (1) 'In addition to the type packing, by inserting the safety ring (9) made of copper or copper alloy, the safety ring (9) expands when the valve receives heat in the event of a fire, thereby preventing and preventing gas leakage and preventing gas accidents and large accidents. It is a very useful design.
