Description

배관 역류방지용 판 체크밸브{Plate check valve for pipe flowing backward prevention}Plate check valve for pipe flowing backward prevention}

본 발명은 배관 역류방지용 판 체크밸브에 관한 것으로, 더욱 상세하게는 물이나 스팀, 각종 유류 등의 작동 유체가 한 방향으로 이송되어 와류발생시 배관 이음 부분에서 역류되지 않으면서 누수, 누유, 누기 예방으로 신뢰성과 안정성을 향상시키는 배관 역류방지용 판 체크밸브에 관한 것이다.The present invention relates to a plate check valve for preventing a pipe backflow, and more particularly, to prevent leakage, leakage, and leakage while the working fluids such as water, steam, and various oils are transferred in one direction without being flowed back from the pipe joint when vortex occurs. The present invention relates to a plate check valve for preventing a pipe backflow to improve reliability and stability.

주지된 바와 같이 판 체크밸브는 배관 이음시 플랜지와 플랜지 사이에 설치되어 물, 스팀, 각종 유류 등이 한 방향으로만 흐르도록 안내하면서 역류하지 못하도록 하는 기능을 갖는다.As is well known, the plate check valve is installed between the flange and the flange at the time of pipe joint, and has a function of preventing water from flowing backward while guiding water, steam, and various oils to flow in only one direction.

이와 같은 판 체크밸브는 도 3과 도 4에 도시된 바와 같이 배관 이음 부분에 플랜지와 플랜지 사이에 설치되는 것으로, 동체(101) 내부에 입구통로(102)를 개폐하는 밸브 개폐판(103)이 출고통로(105)를 갖는 스프링 지지판(106)에 의해 보유 지지된 압축 스프링(107)으로 탄발 설치되어 있다.3 and 4, the plate check valve is installed between the flange and the flange in the pipe joint portion, and the valve opening and closing plate 103 for opening and closing the inlet passage 102 inside the body 101 is provided. It is provided with the compression spring 107 hold | maintained by the spring support plate 106 which has the delivery passage 105.

이러한 종래 판 체크밸브는 관로 내로 매우 큰 압력의 유체, 물, 기체가 입구통로(102)를 통하여 출구통로(105) 쪽으로 갑작스럽게 흐를 경우, 관로 내에 와 류가 발생하여 특정방향으로 회전하게 되는데, 이 작동 유체의 와류에 의해 밸브 개폐판(103)이 회전하면서 압축 스프링(107)의 양단과 마찰을 일으키게 되고, 이로 인하여 이 압착 스프링(107)의 장력 소실 또는 변형이 발생하게 되고, 판 체크밸브의 고유기능인 일방향 흐름 기능을 상실하여 유기체가 반대방향으로 역류하게 되는 현상이 발생하였다.This conventional plate check valve is a fluid, water, gas of a very large pressure into the conduit flows suddenly through the inlet passage 102 toward the outlet passage 105, the vortex is generated in the conduit is rotated in a specific direction, Vortex of the working fluid causes friction with both ends of the compression spring 107 as the valve opening and closing plate 103 rotates, thereby causing tension loss or deformation of the compression spring 107, resulting in a plate check valve. The loss of one-way flow, which is inherent in, caused the organism to flow back in the opposite direction.

이에 본 발명은 상기와 같은 목적을 달성하기 위하여 발명된 것으로, 밸브 개폐판의 축을 개량시키어 작동 유체에 의한 동작시 이 밸브 개폐판이 작동 유체의 와류 여부와 상관없이 직선 왕복운동만을 하도록 하여 판 체크밸브의 수명연장과 누수, 누기, 누유 등이 예방되어 안정적 작동으로 신뢰성이 향상된 배관 역류방지용 판 체크밸브를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to achieve the above object, by improving the axis of the valve opening and closing plate to operate the working fluid, the valve opening and closing plate so that only the linear reciprocating motion regardless of whether the working fluid vortex plate check valve Its purpose is to provide a plate check valve to prevent backflow of pipes, which improves reliability by prolonging service life and preventing leakage, leakage, and leakage.

상기와 같은 목적을 달성하기 위한 본 발명은 동체 내부에 입구통로를 개폐하는 밸브 개폐판이 축으로 지지되어 출구통로를 갖는 스프링 지지판에 보유 지지된 압축 스프링에 의해 탄발 설치되어 이루어진 배관 역류방지용 판 체크밸브에 있어서, 상기 밸브 개폐판의 축은 이의 단면이 6각형으로 형성되어 밸브 개폐판의 좌우 회전을 방지하도록 이루어져 있다.In order to achieve the above object, the present invention provides a check valve for preventing a pipe backflow which is installed by a compression spring held on a spring support plate having a valve opening and closing plate for opening and closing an inlet passage in a fuselage. In the shaft of the valve opening and closing plate is formed in a hexagonal cross-section thereof is made to prevent the left and right rotation of the valve opening and closing plate.

상기와 같은 본 발명에 따른 배관 역류방지용 판 체크밸브는 배관 내부에 설치되어 작동 유체의 와류 발생시 밸브 개폐판과 동체의 기밀을 유지시키는 압축 스프링의 손상을 예방하여 판 체크밸브의 안정성과 신뢰성을 극대화하면서 수명연장의 효과도 지닌다.The pipe backflow prevention plate check valve according to the present invention as described above is installed inside the pipe to prevent the damage of the compression spring to maintain the air tightness of the valve opening and closing plate and the body when the vortex of the working fluid to maximize the stability and reliability of the plate check valve It also has the effect of extending life.

이하, 본 발명을 첨부도면을 참고하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 배관 역류방지용 판 체크밸브의 평면도이고, 도 2는 도 1의 Ⅰ-Ⅰ선 단면도이다.1 is a plan view of a plate check valve for preventing a pipe backflow in accordance with the present invention, Figure 2 is a cross-sectional view taken along the line I-I of FIG.

본 발명은 배관의 이음 부분에 있는 플랜지와 플랜지 사이에 설치되어 유체가 일방 향으로만 흐르도록 작용하는 판 체크밸브로서, 동체(1) 내부에 입구통로(2)를 개폐하는 밸브 개폐판(3)이 축(4)으로 지지되어 출구통로(5)를 갖는 스프링 지지대(6)에 보유 지지된 압축 스프링(7)에 의해 탄발 설치되어 이루어진 배관 역류방지용 판 체크밸브에 있어서, 상기 밸브 개폐판(3)의 축(4)은 이의 단면이 6각형으로 형성되어 밸브 개폐판(3)의 좌우 회전을 방지하도록 되어 있다.The present invention is a plate check valve installed between the flange and the flange in the joint of the pipe acts to flow only in one direction, the valve opening and closing plate (3) for opening and closing the inlet passage (2) inside the body (1) In the check valve of the pipe backflow prevention plate which is supported by the shaft (4) and is installed by the compression spring (7) held on the spring support (6) having the outlet passage (5), the valve opening and closing plate ( The shaft 4 of 3) has a hexagonal cross section thereof to prevent left and right rotation of the valve opening and closing plate 3.

즉, 본 발명은 입구통로(2)를 통하여 유입되는 작동 유체가 화살표 방향으로만 안내하여 출구통로(5) 쪽으로 빠져나가도록 작용하는 판 체크밸브로서, 압축 스프링(7)으로 탄지된 밸브 개폐판(3)의 축(4)이 6각형 기둥으로 형성되어 육각구멍(8)에 끼워짐에 따라 작동 유체의 와류 작용시 6각형 기둥의 모서리들에 의해 상기 밸브 개폐판(3)이 좌우로 회전되지 않는다.That is, the present invention is a plate check valve which acts to guide the working fluid flowing through the inlet passage (2) only to the direction of the arrow to exit the outlet passage (5), the valve opening and closing plate supported by the compression spring (7) As the shaft 4 of (3) is formed into a hexagonal pillar and fitted into the hexagonal hole 8, the valve opening and closing plate 3 rotates left and right by the corners of the hexagonal pillar during the vortex action of the working fluid. It doesn't work.

이로 인해 밸브 개폐판(3)의 좌우 회전방지로 압축 스프링(7)의 변형과 장력손실을 방지하여 판 체크밸브의 안정성과 신뢰성을 향상시키도록 되어 있다.This prevents deformation and tension loss of the compression spring 7 by preventing the left and right rotation of the valve opening and closing plate 3 to improve the stability and reliability of the plate check valve.

한편, 상기 축(4)은 6각형 기둥뿐만 아니라 필요에 따라 다각형 기둥으로 형성되고, 이에 맞도록 축 삽입구멍도 그 단면이 다각형으로 형성됨은 물론이다.On the other hand, the shaft 4 is not only a hexagonal pillar, but also formed of a polygonal pillar as necessary, and the shaft insertion hole is also formed of a polygonal cross-section so as to fit.
