Abstract

The present invention relates to a straight type safety valve, which is a device for preventing a pressure from rising to a set pressure or greater by operating when the pressure becomes the set pressure. An existing valve comprises: a body shown to the outside of the valve; and a cover. So, the existing invention has many problems of safety as the body fixes a part divided into two parts when power is applied to the body and a sheet is difficult to be replaced due to a connection method of the sheet, wherein the existing valve also has deformation as the sheet cannot endure proper bolt coupling power when pipes are coupled. According to the present invention, the body is replaced in an integral type. The sheet and a disc spring unit are inserted into an outlet and are blocked by the cover to be coupled to the pipe. So, the sheet has less deformation, and there is no need to seal the outside. The body is the integral type so that the body can endure external power well, and a sheet disc can be easily replaced when the sheet disc is damaged. So, the straight type safety valve is economically safe. The body unit absorbs the power in a strong connection when an inlet is coupled. So, the small power is applied to the sheet unit, and the safety valve has low deformation of the sheet unit.

Description

일자형안전밸브{Straight type safety valve}[0001] The present invention relates to a straight type safety valve,

정해진 압력 이상 이되면 작동하여 압력을 제거해주는 밸브에 관한것이다. And a valve that operates when the pressure exceeds a predetermined pressure to remove the pressure.

안전밸브의 형태는 여러형태가 있고 기본형태는 디스크가 있고 디스크 위쪽에서 힘을 가할수 있는 물체 보통 스프링을 이용하여 정해진 힘으로 누르고 있다 설정압이상이 되면 열리게 되어 압력을 해소하는 밸브이다. The safety valve has several forms, the basic form is a disk, and an object that can apply force from the top of the disk. Normally, it uses a spring to hold it down with a fixed force.

발명자인 조승호는 밸브회사에서 근무해 왔고 설계와 수리업무를 해왔었다.The inventor, Cho Seung-ho, has worked for a valve company and has been in the design and repair business.

수리업무는 삼성전자 화성공장과 기흥에서 했다. 가장 안전해야 하는 안전밸브가 아주 위험한 강한 염기성물질이나 강산성의 물질이 담긴 탱크위에 설치되지만 안전밸브의 문제로 잘 작동하지 않거나 밸브가 설정압력이상으로 올라가지 않음에도 불구하고 밸브내부가 강산이나 강염기로 녹이 슬어 잘작동하지 않는 안전밸브도 있었다.밸브바디는 SUS316L재질로 녹이 슬지 않는 재질이다. 사용중인 유체인 강산이나 염기에는 약해 녹이 슬어버린다. 리크가 있다고 볼수있다. Repair work was done at Samsung Electronics' Hwasung Plant and Giheung. The safety valve, which is the most secure, is installed on a tank containing strong basic substance or strongly acidic substance, which is very dangerous, but it does not operate well due to the safety valve problem or the valve is rusted with strong acid or strong base The valve body was made of SUS316L material which does not rust. Rust acid or base, which is the fluid in use, is rusty and rusty. There is a leak.

안전밸브 조립시 커버고정나사를 약하게 조이면 커버가 돌아가 유체가 새어나올수 있고 강하게 조이면 내부디스크작동부에 영향을주어 디스크가 작동을 하지않는다. 안전밸브 체결시 입구부에 파열판이 설치되는데 안전밸브 체결시 파열판은 적절한 힘으로 체결하지만 안전밸브의 입구부는 그힘을 견디지 못하고 입구부의 시트부가 변형이 되어 리크가 발생하고 안전밸브로 기능을 하지 못하게 되는것이다.When assembling the safety valve, if the cover fixing screw is tightened slightly, the cover will turn and the fluid will leak out. If it is tightened tightly, it will affect the internal disk operation and the disk will not operate. When the safety valve is tightened, the rupture plate is installed at the entrance part. When the safety valve is tightened, the rupture plate is tightened with a proper force. However, the entrance part of the safety valve can not withstand the force and the seat part of the entrance part deforms, will be.

이때 변형된 시트의 재질은 테프론으로 되어있다. The material of the deformed sheet is Teflon.

탱크위에 파열판과 안전밸브가 연결되고 그위로 배관이 연결된다 이배관이 전체적으로 움직인다면 지진이나 외부 어떤힘으로 인해 그렇게 된다면 상부커버 하부바디로 나누어진 안전밸브는 그힘을 견디지 못하고 커버부가 돌아가 그사이로 리크가 발생하거나 커버 고정나사가 바디부를 눌러 작동상의 문제가 일어날수도 있다. 테프론시트가 변형이나 데미지 입을시에 교체가 불가능하여 밸브 전체를 교체하여야 하는 경제적인문제도 발생한다. 그리고 밸브자체 봉인이라해서 외부에서 조작을 못하게 묵어두는 줄이 있는데If the piping is moved as a whole, if it is caused by an earthquake or any external force, the safety valve divided by the lower body of the upper cover will not be able to withstand the force, Or the cover fixing screw may press on the body portion to cause an operational problem. The Teflon sheet can not be replaced at the time of deformation or damage, and the entire valve needs to be replaced. And since the valve itself is sealed, there is no way to keep it from outside

상부커버 고정나사에 이줄이 묵여 있다. 배관에서 체결 분해 작업시 방해가 되어 능률이 오르지 않는다.The upper cover fixing screw is threaded. It does not increase efficiency because it interferes with fastening and disassembly work in piping.

안전밸브자체에 문제가 있지만 회사 자체적으로 아무것도 할수도 없었다. There was a problem with the safety valve itself, but the company itself could not do anything.

위와 같은 문제가 있고 해결하려는 과제는 보다 안전한 안전밸브를 만들고 싶어서이다.I have the above problem and the problem to solve is to make safer safety valve.

상기와 같은 문제의 해결수단은 밸브가 분리형이 아닌 하나의 바디를 가지며 출구부의 구멍으로 통해 바디안으로 삽입되는 뭉치에 디스크 시트를 삽입 고정 하는 것이다. The solution to such a problem is that the valve has one body, not a separable type, and the disk sheet is inserted and fixed into the bundle which is inserted into the body through the hole of the outlet portion.

바디부가 일체형이라 봉인줄이 불필요 하며 외부의 힘(지진이나 배관의 무게)에 디스크와 시트의 변형을 막으며 작동을 원할히 하고 시트와 디스크 데미지시 교체가 가능해 오래사용할수 있으며 입구부의 강한조임에도 시트부의 변형이 최소화해 안전밸브 기능을 상실할 확률도 적은 밸브Because the body part is integral, it does not need a seal line. It prevents deformation of disc and seat by external force (earthquake or piping weight) and makes it easy to operate. It can be used for sheet and disc damage and can be used for a long time. Valve is less likely to lose safety valve function due to minimal deformation
