Abstract

An apparatus for preventing leakage of oil through a gas pressure control valve of an oil carrier is provided to prevent the leakage of the oil by temporarily stopping the function of the pressure control valve when the leakage of the oil is predicted. An apparatus for preventing leakage of an oil through a gas pressure control valve of an oil carrier comprises a support member(110) and a ball member(120). The support member surrounds a lower portion of a hole formed in an oil storage tank of the oil carrier to form a space communicated with the hole. A plurality of openings is formed in the support member to flow the gas in the oil storage tank through the hole. The ball member is installed in the space formed by the support member. If an external force is not applied, the ball member forms a space for flow of a gas. The ball member closes the hole if a sloshing phenomenon is generated.

본 발명은 원유의 누출을 방지하는 장치에 관한 것으로, 특히 원유 운반선의 원유저장탱크에 구비된 압력조절밸브를 통해 원유가 누출되는 것을 방지하는 원유 누출방지장치에 관한 것이다.The present invention relates to a device for preventing the leakage of crude oil, and more particularly to a crude oil leakage prevention device for preventing the leakage of crude oil through a pressure control valve provided in the crude oil storage tank of the crude oil carrier.

일반적으로 선박은 사람이나 가축 또는 각종 화물을 싣고 해상을 통해 목적지까지 이동하는 교통수단으로서, 다른 교통수단에 비하여 대량의 화물을 한번에 이동시킬 수 있다는 점에서 널리 사용되고 있다.In general, a ship is a means of transporting a person, a livestock, or various cargoes to the destination by sea, and is widely used in that a large quantity of cargo can be moved at a time compared to other transportation means.

한편, 원유 운반선의 경우, 원유 운반 탱크에 통상 95% 이상의 원유를 적재하고 있으며, 탱크 상부는 원유에서 발생하는 각종 인화성 가스에 의한 불의의 사고를 방지하고자 고압의 비인화성 가스로 채워지게 되며, 탱크 상부에는 가스 압력을 일정하게 유지하기 위한 고속 압력조절밸브가 설치되어 있다. 이러한 압력조절밸브는 탱크내 가스의 압력이 높아지면 밸브의 마개역할을 하는 부품이 압력에 의해 개방되어 가스를 분출함으로써 압력을 유지하도록 되어 있다.On the other hand, in the case of crude oil carriers, more than 95% of the crude oil is usually loaded in the crude oil carrying tank, and the upper part of the tank is filled with high-pressure non-flammable gas to prevent accidents caused by various flammable gases generated in the crude oil. The upper part is provided with a high speed pressure regulating valve for maintaining a constant gas pressure. When the pressure of the gas in the tank is increased, such a pressure regulating valve is configured to maintain the pressure by opening a component which acts as a stopper of the valve by ejecting the gas.

한편, 원유를 저장하고 있는 원유 운반선이 거친 해역을 운항할 경우, 원유의 수면이 활발하게 움직이는 슬로싱 현상이 발생된다. 이러한 슬로싱 현상에 의해 원유가 탱크의 상부로 튀어올라 압력조절밸브에 충격을 가하게 되며, 이때 가스압력이 높아질 때만 작동해야 하는 압력조절밸브가 원유의 충격압력에 의해 오작동하여 순간적으로 개방됨으로써 원유가 압력조절밸브를 통해 누출되는 일이 빈번히 발생하고 있다.On the other hand, when the crude oil carriers storing crude oil operate in rough seas, sloshing phenomenon occurs in which the surface of the crude oil is actively moved. Due to this sloshing phenomenon, crude oil springs up to the top of the tank and impacts the pressure regulating valve.At this time, the pressure regulating valve, which should be operated only when the gas pressure is high, malfunctions by the impact pressure of the crude oil and opens it momentarily, thereby regulating the pressure of the crude oil. Leaking through valves is a frequent occurrence.

상기와 같은 원유의 누출을 방지하기 위해 압력조절밸브의 하부에 수직으로 저항판을 설치하여 원유의 누출을 방지하고자 하였으나, 원유 누출을 근본적으로 차단할 수 없는 문제점이 있었다.In order to prevent the leakage of crude oil as described above to prevent the leakage of crude oil by installing a resistance plate perpendicular to the lower portion of the pressure control valve, there was a problem that can not fundamentally block the leakage of crude oil.

본 발명은 상기와 같은 문제점을 고려하여 이루어진 것으로, 본 발명의 목적은 원유 운반선에 저장된 원유에 슬로싱 현상이 발생되어 압력조절밸브 측으로 튀어 올라 밸브를 통한 원유의 유출이 예상될 때 압력조절밸브의 기능을 일시적으로 정지시켜 원유의 누출을 방지하는 원유 운반선의 가스압력조절밸브를 통한 원유 누출방지장치를 제공함에 있다.The present invention has been made in consideration of the above problems, and an object of the present invention is that a sloshing phenomenon occurs in the crude oil stored in the crude oil carrier and springs up to the pressure regulating valve side of the pressure regulating valve when the oil is expected to leak through the valve. The present invention provides a crude oil leakage preventing device through a gas pressure control valve of a crude oil carrier that temporarily stops a function to prevent leakage of crude oil.
