원유 저장기지와 같은 대형시설에 구비된 유류저장탱크는 유류의 저장과 경제적인 문제를 고려하여 직경의 크기가 수십 미터에 이르는 대형으로 만들어져 있다.The oil storage tank provided in a large facility such as a crude oil storage base is made of a large size of several tens of meters in diameter considering the storage of oil and economic problems.

이러한 유류저장탱크에 저장되는 석유와 같은 유류는 휘발성이 강하기 때문에 저장탱크 내에 저장하고 있는 동안에 기화에 의한 증발이 일어나게 되는데, 특히 대형 유류저장탱크에서는 평면적이 크기 때문에 증발 현상이 더욱 심하게 나타나서 다량의 휘발성 유기화합물(Volatile organic compounds:VOCs, 이하, '유증기')이 발생한다.Since oil such as oil stored in the oil storage tank is highly volatile, evaporation by evaporation occurs during storage in the storage tank. In particular, in large oil storage tanks, the evaporation phenomenon appears more severely due to the large flat surface, so a large amount of volatility Volatile organic compounds (VOCs, hereinafter,'vapours') are generated.

유증기는 인체에 유해한 독성물질(벤젠, 톨루엔, 자일렌, NOX 및 알데히드 등)을 포함하고 있어 대기오염의 원인이 될 뿐만 아니라 대기배출로 인하여 원유의 손실이 발생되므로 대기 중으로 배출되지 않도록 할 필요가 있다.Oil vapor contains toxic substances (benzene, toluene, xylene, NOX and aldehydes, etc.) that are harmful to the human body, which is not only a source of air pollution, but also causes loss of crude oil due to air emissions, so it is necessary to avoid discharge to the atmosphere. have.

특히, 외유부상덮개탱크와 같이 유면의 높이에 따라 외유부상덮개가 상하로 움직이는 유류저장탱크의 경우에도 유증기의 대기유출을 방지하기 위한 씰링구조를 구비하고 있는데, 이 외유부상덮개탱크에 구비된 종래의 씰링구조는 도 1에 도시된 바와 같이 접착제에 의해 내측면에 씰링부재(1)가 부착된 커버(2)를 통기파이프(3)의 상단에 설치하는 구성을 취하고 있다.Particularly, in the case of an oil storage tank in which the external oil floating cover moves up and down according to the height of the oil level, such as the external oil floating cover tank, a sealing structure is provided to prevent the air from leaking into the air, which is provided in the external oil floating cover tank. The sealing structure of as shown in FIG. 1 has a configuration in which the cover 2 with the sealing member 1 attached to the inner surface by an adhesive is installed on the top of the ventilation pipe 3.

그러나, 이러한 종래의 구조는 시간이 경과하면서 유증기의 부식에 의해 접착제가 멜팅(Melting)되면서 씰링부재에 손상이 발생하게 되고, 이로 인하여 제대로 씰링(Sealing)이 되지 않아 유증기가 대기 중으로 유출되는 문제가 있었다.However, such a conventional structure causes damage to the sealing member as the adhesive melts due to corrosion of the vapor over time, and as a result, there is a problem in that the vapor does not seal properly, so that the vapor leaks into the atmosphere. there was.

공개특허 : 10-2015-0100278 (출원번호 : 10-2014-0021881, 발명의 명칭: 원유 저장탱크용 벤트장치)Patent Publication: 10-2015-0100278 (Application No.: 10-2014-0021881, Title of the invention: Venting device for crude oil storage tank)

본 발명은 상기한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 접착제를 사용하지 않고 씰링부재를 설치하여 유증기의 부식에 의해 접착제가 멜팅됨으로써 씰링부재가 훼손되는 것을 방지할 수 있는 외유부상덮개탱크에 설치된 진공방지통기밸브체를 제공하는데 그 목적이 있다.The present invention has been devised to solve the problems of the prior art described above, and by installing a sealing member without using an adhesive, the adhesive member is melted by corrosion of oil vapor, thereby preventing the sealing member from being damaged. The purpose of the present invention is to provide a vacuum-prevention vent valve body.

또한, 씰링부재의 훼손을 막으면서도 밀폐력을 더욱 향상시켜 유증기의 누출을 효율적으로 차단할 수 있는 외유부상덮개탱크에 설치된 진공방지통기밸브체를 제공하는데 그 목적이 있다.In addition, the object of the present invention is to provide a vacuum-prevention vent valve body installed in an external floating cover tank that can effectively prevent leakage of oil vapor by further improving the sealing force while preventing damage to the sealing member.

상기한 과제를 해결하기 위한 본 발명에 의한 외유부상덮개탱크에 설치된 진공방지통기밸브체는 유류저장탱크의 내부공간과 연통되게 유류저장탱크의 외유부상덮개 상면에 설치되는 통기파이프와; 상기 통기파이프의 상단부분을 둘러싸는 씰링부재와; 상기 씰링부재를 둘러싸도록 설치되되, 유증기 배출시 또는 외부공기 유입시 상승하여 씰링부재와 이격되는 커버와; 상기 커버에 고정되고, 상기 커버를 관통하여 상기 유류저장탱크의 내외부로 연장되게 설치되는 서포트 레그;로 구성된다.The vacuum prevention vent valve body installed in the outer oil floating cover tank according to the present invention for solving the above problems includes a ventilation pipe installed on the upper surface of the outer oil floating cover of the oil storage tank to communicate with the inner space of the oil storage tank; A sealing member surrounding an upper portion of the ventilation pipe; A cover which is installed to surround the sealing member, and rises when vapor is discharged or when external air flows in and is spaced apart from the sealing member; It is fixed to the cover, the support leg is installed to extend through the cover to extend to the inside and outside of the oil storage tank.

여기서, 상기 씰링부재는 상기 통기파이프의 상단 내측면에 밀착되는 내부 밀착부와; 상기 통기파이프의 상단 외측면에 밀착되는 외부 밀착부와; 상기 내부 밀착부와 외부 밀착부의 상단에 일체로 연결되어 상기 통기파이프와 커버 사이에서 압착되는 링형 밀착부;로 구성된다.Here, the sealing member and the inner contact portion in close contact with the upper inner surface of the ventilation pipe; An external contact portion in close contact with the upper outer surface of the ventilation pipe; Consists of a ring-shaped contact portion that is integrally connected to the upper end of the inner and outer contact portions and compressed between the ventilation pipe and the cover.

그리고, 상기 링형 밀착부는 내부에 원형의 빈 공간이 형성되어 그 상하방향 단면이 원형고리 형태로 구성된다.In addition, the ring-shaped contact portion has a circular empty space formed therein, and its vertical cross-section is formed in a circular ring shape.

또한, 상기 내부 밀착부와 상기 외부 밀착부는 상기 통기파이프를 바라보는 면의 하측부분이 테이퍼진다.In addition, the lower portion of the surface facing the ventilation pipe is tapered to the inner contact portion and the outer contact portion.

또한, 상기 외부 밀착부의 외측면을 둘러싸서 가압하는 스테인레스 스틸밴드가 더 설치된다.In addition, a stainless steel band surrounding the outer surface of the external contact portion and pressing is further installed.

또한, 상기 통기파이프의 중앙에 위치되어 상기 서포트 레그의 외측면을 지지하는 링 지지부와, 상기 링 지지부의 외측면과 상기 통기파이프의 내측면을 연결하는 다수의 브릿지로 이루어진 레그 지지부가 더 구비된다.In addition, a ring support portion which is located at the center of the ventilation pipe to support the outer surface of the support leg, and a leg support composed of a plurality of bridges connecting the outer surface of the ring support portion and the inner surface of the ventilation pipe are further provided. .

상기와 같이 구성되는 본 발명의 외유부상덮개탱크에 설치된 진공방지통기밸브체는 접착제를 전혀 사용하지 않고 씰링부재를 설치하기 때문에, 유증기의 열에 의한 접착체의 멜팅(Melting)으로 인해 씰링부재가 손상되는 것을 방지함으로써, 유증기가 누출되는 것을 지속적으로 차단할 수 있는 이점이 있다.Since the vacuum-preventing vent valve body installed in the outer floating cover tank of the present invention configured as described above installs a sealing member without using any adhesive, the sealing member is damaged due to melting of the adhesive body due to heat of the vapor. By preventing it, there is an advantage that can continuously block the leakage of oil vapor.

또한, 단면이 원형고리 형태인 링형 밀착부가 커버에 의해 눌려 찌그러지면서 옆방향으로 확장되기 때문에, 커버와 씰링부재 사이에 빈 공간이 발생되지 않아서 유증기 누출을 더욱 효율적으로 차단할 수 있는 이점이 있다.In addition, since the ring-shaped contact portion having a circular ring cross-section is pushed and crushed by the cover and expands in the lateral direction, there is no advantage that an empty space is not generated between the cover and the sealing member, so that vapor leakage can be more efficiently blocked.

또한, 스테인레스 스틸밴드로 외부 밀착부 주위를 가압하기 때문에, 통기파이프에 대한 씰링부재의 결속력을 더욱 향상시킬 수 있는 이점이 있다.In addition, since the stainless steel band is pressed around the outer contact portion, there is an advantage that can further improve the binding force of the sealing member to the ventilation pipe.

본 발명에 의한 외유부상덮개탱크에 설치된 진공방지통기밸브체는 유류저장탱크 내부의 유류에서 증발된 유증기의 압력이 일정 수준 이상이 되었을 때 유증기를 외부로 배출시키는 한편, 유류저장탱크 내부의 유류가 외부로 배출될 때 탱크 내부에 발생하는 진공상태를 해소하기 위해 외부공기가 유입되도록 하기 위하여 설치된다.The vacuum-prevention vent valve body installed on the outer oil floating cover tank according to the present invention discharges vapor to the outside when the pressure of the vaporized vapor from the oil in the oil storage tank exceeds a certain level, while the oil inside the oil storage tank It is installed to allow external air to flow in to relieve the vacuum state that occurs inside the tank when discharged to the outside.

이러한 외유부상덮개탱크에 설치된 진공방지통기밸브체는 통기파이프(10)와, 상기 통기파이프(10)에 설치되는 씰링부재(20)와, 상기 씰링부재(20)에 설치되는 커버(30)와, 상기 커버(30)에 고정 설치되는 서포트 레그(40)를 포함하여 구성된다.The vacuum prevention ventilation valve body installed in the external floating cover tank includes a ventilation pipe 10, a sealing member 20 installed on the ventilation pipe 10, and a cover 30 installed on the sealing member 20. , It comprises a support leg 40 fixed to the cover 30 is installed.

상기 통기파이프(10)는 원형 파이프 형태를 갖는 것으로서, 유류가 충진되어 있는 유류저장탱크의 내부공간과 연통되게 유류저장탱크의 외유부상덮개(C) 상면에 설치된다.The ventilation pipe 10 has a circular pipe shape, and is installed on the upper surface of the outer floating cover C of the oil storage tank in communication with the inner space of the oil storage tank filled with oil.

이러한 통기파이프(10)의 내부에는 레그 지지부(11)가 구비된다.A leg support portion 11 is provided inside the ventilation pipe 10.

상기 레그 지지부(11)는 링 지지부(11a)와, 상기 링 지지부(11a)에 연결되는 다수의 브릿지(11b)로 구성된다.The leg support 11 is composed of a ring support 11a and a plurality of bridges 11b connected to the ring support 11a.

상기 링 지지부(11a)는 통기파이프(10)의 중앙에 위치되어 서포트 레그(40)의 외측면을 둘러싸고 지지한다. 따라서 서포트 레그(40)는 커버(30)의 체결부(31a)를 관통하여 체결되면서 동시에 링 지지부(11a) 내부에 삽입되기 때문에, 서포트 레그(40)가 흔들리는 것이 방지된다.The ring support portion 11a is positioned at the center of the ventilation pipe 10 to surround and support the outer surface of the support leg 40. Therefore, since the support leg 40 is fastened through the fastening part 31a of the cover 30 and simultaneously inserted into the ring support part 11a, the support leg 40 is prevented from shaking.

상기 브릿지(11b)는 링 지지부(11a)의 외측면과 통기파이프(10)의 내측면을 연결한다. The bridge 11b connects the outer surface of the ring support 11a and the inner surface of the ventilation pipe 10.

상기 씰링부재(20)는 통기파이프(10)의 상단부분을 둘러싸도록 설치되는 것으로서, EPDM(Ethylene Propylene Diene Monomer) 발포(Foamed) 재질로 만들어져 내구성 및 밀착성이 향상되었다.The sealing member 20 is installed to surround the upper portion of the ventilation pipe 10, and is made of Ethylene Propylene Diene Monomer (EPDM) foamed material to improve durability and adhesion.

이러한 씰링부재(20)는 내부 밀착부(21)와, 상기 내부 밀착부(21)의 바깥쪽에 위치되는 외부 밀착부(22)와, 상기 내부 밀착부(21)와 외부 밀착부(22)의 상단에 일체로 연결되는 링형 밀착부(23)로 구성된다.The sealing member 20 includes an inner contact portion 21, an outer contact portion 22 positioned outside the inner contact portion 21, and an inner contact portion 21 and an outer contact portion 22. It is composed of a ring-like contact portion 23 integrally connected to the top.

상기 내부 밀착부(21)는 일정한 직경을 갖는 원형의 고리 형태를 취하는 것으로서, 통기파이프(10)의 상단 내측면에 밀착된다.The inner contact portion 21 takes the form of a circular ring having a constant diameter, and is in close contact with the upper inner surface of the ventilation pipe 10.

상기 외부 밀착부(22)는 원형의 고리 형태를 취하는 것으로서, 내부 밀착부(21)보다 큰 직경을 갖도록 형성되어 내부 밀착부(21)의 바깥쪽에 위치된다. 이러한 외부 밀착부(22)는 통기파이프(10)의 상단 외측면에 밀착된다. 따라서, 통기파이프(10)의 상단 부분은 씰링부재(20)의 내부 밀착부(21)와 외부 밀착부(22) 사이의 공간에 끼워진다.The outer contact portion 22 takes the form of a circular ring, and is formed to have a larger diameter than the inner contact portion 21 and is positioned outside the inner contact portion 21. The external contact portion 22 is in close contact with the upper outer surface of the ventilation pipe (10). Therefore, the upper portion of the ventilation pipe 10 is fitted in the space between the inner contact portion 21 and the outer contact portion 22 of the sealing member 20.

상기 링형 밀착부(23)는 상기 내부 밀착부(21)와 외부 밀착부(22)의 상단에 일체로 연결된다. 이러한 링형 밀착부(23)는 통기파이프(10)와 커버(30) 사이에서 압착된다.The ring-shaped contact portion 23 is integrally connected to the top of the inner contact portion 21 and the outer contact portion 22. The ring-shaped contact portion 23 is compressed between the ventilation pipe 10 and the cover 30.

부연하면, 링형 밀착부(23)는 내부에 원형의 빈 공간이 형성되어 그 상하방향 단면이 원형고리 형태로 구성된다. 따라서 통기파이프(10)에 씰링부재(20)를 설치하고 씰링부재(20)에 커버(30)를 설치하면 링형 밀착부(23)가 통기파이프(10)와 커버(30) 사이에서 압착이 되어 찌그러지면서 그 폭이 넓어져 커버(30)의 내측면에 링형 밀착부(23)의 가장자리 표면이 밀착된다.If it expands, the ring-shaped contact part 23 has a circular empty space formed therein, and its cross section in the vertical direction is formed in a circular ring shape. Therefore, when the sealing member 20 is installed on the ventilation pipe 10 and the cover 30 is installed on the sealing member 20, the ring-shaped contact portion 23 is compressed between the ventilation pipe 10 and the cover 30. As it is distorted, its width is widened, and the edge surface of the ring-shaped contact portion 23 is in close contact with the inner surface of the cover 30.

한편, 내부 밀착부(21)와 외부 밀착부(22)는 통기파이프(10)를 바라보는 면의 하측부분을 테이퍼지게 구성할 수도 있다. 이렇게 테이퍼지게 구성을 하면 씰링부재(20)를 통기파이프(10)의 상단에 설치할 때 통기파이프(10)의 상단부분이 내부 밀착부(21)와 외부 밀착부(22) 사이에 좀 더 잘 삽입되게 할 수 있다.On the other hand, the inner contact portion 21 and the outer contact portion 22 may be configured to taper the lower portion of the surface facing the ventilation pipe (10). When configured to be tapered like this, when the sealing member 20 is installed on the top of the ventilation pipe 10, the upper portion of the ventilation pipe 10 is better inserted between the inner contact portion 21 and the outer contact portion 22. I can do it.

더불어, 씰링부재(20)를 제작할 때 내부 밀착부(21)와 외부 밀착부(22)가 서로를 향해 가까워지는 방향으로 탄성력이 작용하게 제작을 한다면, 내부 밀착부(21)와 외부 밀착부(22)가 통기파이프(10)의 상단에 좀 더 견고하게 밀착될 수 있다.In addition, when manufacturing the sealing member 20, if the inner contact portion 21 and the outer contact portion 22 are produced so that the elastic force acts in a direction closer to each other, the inner contact portion 21 and the outer contact portion ( 22) may be more firmly adhered to the top of the ventilation pipe (10).

그리고, 상기한 것처럼 씰링부재(20)를 통기파이프(10)의 상단에 설치한 다음에는 씰링부재(20)에 스테인레스 스틸밴드(50)를 설치하여 씰링부재(20)가 더 견고하게 통기파이프(10)에 밀착되게 할 수 있다. 이러한 스테인레스 스틸밴드(50)는 씰링부재(20)의 외측면을 둘러싸서 가압하도록 설치되기 때문에, 스테인레스 스틸밴드(50)는 외부 밀착부(22)를 강한 힘으로 눌러서 통기파이프(10)에 밀착되도록 한다. And, as described above, after the sealing member 20 is installed on the top of the ventilation pipe 10, a stainless steel band 50 is installed on the sealing member 20 to make the sealing member 20 more firmly ventilated pipe ( 10). Since the stainless steel band 50 is installed so as to surround and press the outer surface of the sealing member 20, the stainless steel band 50 is pressed against the external contact portion 22 with strong force to closely adhere to the ventilation pipe 10 As much as possible.

위에서 설명한 것처럼, 본 발명은 씰링부재(20)를 통기파이프(10)에 설치할 때 접착제를 사용하지 않는다. 즉 접착제의 사용 없이 씰링부재(20)의 내부 밀착부(21)와 외부 밀착부(22) 사이에 통기파이프(10)의 상단부분을 삽입하여 설치할 수도 있고, 결속력을 강화하기 위하여 스테인레스 스틸밴드(50)를 사용할 수도 있다. 따라서 유증기의 부식에 의해 접착제가 멜팅(Melting)되어 씰링부재(20)가 손상되는 위험성을 줄일 수 있다.As described above, the present invention does not use an adhesive when the sealing member 20 is installed on the ventilation pipe (10). That is, without using an adhesive, the upper portion of the ventilation pipe 10 may be inserted between the inner contact portion 21 and the outer contact portion 22 of the sealing member 20, and a stainless steel band ( 50) can also be used. Therefore, it is possible to reduce the risk of damage to the sealing member 20 because the adhesive is melted due to corrosion of the vapor.

상기 커버(30)는 상기 씰링부재(20)를 둘러싸도록 설치되어 개방된 통기파이프(10)의 상단을 폐쇄한다. 이러한 커버(30)는 유류저장탱크 내부의 유증기가 일정수준 이상의 압력이 되어 외부로 배출될 때나 유류저장탱크 내부의 진공압력을 해소하기 위하여 외부공기가 유류저장탱크 내부로 유입될 때 위쪽으로 상승하여 씰링부재(20)와 일정거리 이격된다.The cover 30 is installed to surround the sealing member 20 to close the upper end of the open ventilation pipe (10). The cover 30 is upward when the oil vapor inside the oil storage tank is discharged to the outside at a pressure above a certain level or when the outside air flows into the oil storage tank to relieve the vacuum pressure inside the oil storage tank. The sealing member 20 is spaced a certain distance.

좀 더 자세히 설명하면, 커버(30)는 수평면(31)과, 상기 수평면(31)의 가장자리에서 하측으로 연장된 측벽(32)으로 구성된다.In more detail, the cover 30 is composed of a horizontal surface 31 and a side wall 32 extending downward from an edge of the horizontal surface 31.

상기 수평면(31)은 통기파이프(10)의 상단을 개폐하는 부분으로서, 중앙에 체결부(31a)가 돌출 형성되어 있다.The horizontal surface 31 is a portion that opens and closes the upper end of the ventilation pipe 10, and a fastening portion 31a is protruded in the center.

상기 체결부(31a)는 서포트 레그(40)가 볼팅되는 부분으로서, 이 체결부(31a)를 통해 커버(30)와 서포트 레그(40)가 연결된다.The fastening part 31a is a part where the support leg 40 is bolted, and the cover 30 and the support leg 40 are connected through the fastening part 31a.

상기 측벽(32)은 씰링부재(20)를 둘러싸는 부분으로서, 씰링부재(20)의 링형 밀착부(23)가 수평면(31)에 의해 눌려 찌그러질 때 링형 밀착부(23)의 가장자리 부분이 밀착된다.The side wall 32 is a portion surrounding the sealing member 20, the edge portion of the ring-like contact portion 23 when the ring-like contact portion 23 of the sealing member 20 is pressed and crushed by the horizontal surface 31 It comes in close contact.

상기 서포트 레그(40)는 외유부상덮개(C)가 유류저장탱크 내부로 일정깊이 이상 내려가지 않도록 하는 것으로서, 커버(30)를 관통하여 유류저장탱크의 내외부로 연장되게 설치된다. 부연하면, 서포트 레그(40)는 커버(30)의 체결부(31a)를 관통하면서 동시에 체결부(31a)에 볼팅되어 고정되어 상하방향으로 직립 설치된다.The support leg 40 is to prevent the outer oil floating cover (C) from falling below a certain depth into the oil storage tank, and is installed to extend through the cover 30 to the inside and outside of the oil storage tank. If it is added, the support leg 40 penetrates through the fastening portion 31a of the cover 30 and is bolted and fixed to the fastening portion 31a at the same time and installed upright in the vertical direction.

유류저장탱크 내부에 저장된 유류가 외부로 배출될 때 외유부상덮개(C)는 아래로 내려가는데, 이때 외유부상덮개(C)가 일정깊이까지 내려가면 서포트 레그(40)의 하단이 유류저장탱크의 바닥면에 닿게 되고, 결국 외유부상덮개(C)는 더 이상 아래로 내려가지 않게 된다.When the oil stored in the oil storage tank is discharged to the outside, the outer oil levitation cover (C) goes down. At this time, if the oil levitation cover (C) goes down to a certain depth, the lower end of the support leg (40) is the oil storage tank. It comes into contact with the bottom surface, and eventually the outer floating cover C no longer goes down.
