본 고안은 일자형 역류 방지 밸브에 관한 것이다. 일반적으로 각종배관에는 배관내에서 흐르는 유체의 역류를 방지 하기 위해서 첵크 밸브를 설치 한다.The present invention relates to a straight check valve. Generally, check valves are installed in various pipes to prevent backflow of the fluid flowing in the pipes.

이러한 첵크 밸브는 T자형 몸체의 위 덮게, 개폐디스크, 고정핀, 고정볼트로 조립되어 사용하였던 것으로 이러한 종래의 첵크 밸브는 T자형몸체로 좁은곳에 배관이 불편하고 수평 배관시 역류하는 유체를 완전히 차단 할수 없음과 동시에 제작하는 시간이 많이 소요되어 제작단가가 상승하고 불필요한 재료낭비가 문제점이었다. These shank valves were assembled with T-shaped body cover, opening / closing disk, fixing pin, and fixing bolt. These conventional shank valves are uncomfortable in narrow places with T-shaped bodies and completely shut off the fluid flowing back during horizontal piping. At the same time, it took a lot of time to produce, causing a rise in manufacturing costs and unnecessary waste of materials.

이를 개선하고자, 일자형태 본체(1)로 양쪽에 나사부(2)를 형성하고 밸브실내(3)에 상,하로 홈(4-1)(4-2)을 낸 개폐 디스크(4)에 ㄱ자 스프링(5)을 조립 고정하는 일자형 역류 방지밸브. 따라서 본 고안의 목적은, 상기와 같은 종래의 문제점을 감안하여 일자형태로 재료원가가 적고 좁은곳에서도 배관이 용이하다.In order to improve this, the threaded portion 2 is formed on both sides of the straight body 1, and the L-shaped spring is formed on the opening / closing disk 4 having the grooves 4-1 and 4-2 up and down in the valve chamber 3. Straight type backflow check valve for assembling and fixing (5). Therefore, the object of the present invention, in view of the conventional problems as described above, the material cost in the form of a straight line is easy to pipe even in narrow places.

본 고안의 다른 목적은 수직배관과 수평배관시 역류를 개폐디스크(4)에 같이 조립되어 있는 ㄱ자 스프링(5)에 의해 유체의 흐름과 관계없이 자동 폐되어 역류를 방지한다. (도면 6)Another object of the present invention is to prevent the backflow is automatically closed irrespective of the flow of the fluid by the A-shaped spring (5) which is assembled to the opening and closing disk (4) as the vertical flow and horizontal piping. (Fig. 6)

본 고안의 다른 목적은 유체가 밸브실내(3)로 유입시 개폐 디스크(4)가 벽에 붙이쳐 소리가 나는 현상이 발생한다. 이러한 현상을 개폐 디스크(4)에 홈(4-1)(4-2)을 형성하여 ㄱ자 스프링(5)을 고정하여 탄성 바이어스 되도록 함으로써 유체를 제어하여 벽에 붙이쳐 소리나는 현상을 방지한다.Another object of the present invention is that when the fluid flows into the valve chamber 3, the opening and closing disk 4 sticks to the wall, the sound occurs. This phenomenon is formed by the grooves 4-1 and 4-2 in the opening / closing disk 4 to fix the L-shaped spring 5 so as to be elastically biased to control the fluid to prevent the phenomenon of sticking to the wall.

본 고안은 상기 목적을 달성 하기위해 일자형태로 본체(1) 양쪽에 나사부(2)를 형성하고 중간에 밸브실(3)과 개폐디스크(4)를 본체(1)에 고정되어 유체의 역류를 방지토록 된것으로서, 상기 개폐 디스크(4) 상단과 하단에 홈(4-1)(4-2)이 형성되어 있고, 상단을 고정핀(6)으로 고정할 수 있게 가공하여 개폐 디스크(4)상단과 하단 홈(4-1)(4-2)에 ㄱ자스프링(5)을 끼워 지게 되고 다시 본체(1)에 고정하여 본체(1)에 탄력적으로 지지토록 되어있는 특징이있다.The present invention forms a threaded portion (2) on both sides of the body (1) in the form of a straight line to achieve the above object, and the valve chamber (3) and the opening and closing disk (4) is fixed to the body (1) in the middle of the back flow of the fluid As to prevent, the opening and closing disk (4) is formed in the upper and lower grooves (4-1) (4-2), the upper and lower processing disk to be fixed by the fixing pin (6) The A-shaped spring 5 is inserted into the upper and lower grooves 4-1 and 4-2, and is fixed to the main body 1 again so that the main body 1 is elastically supported.

본 고안은 배관내에서 흐르던 유체는 나사부(2)를 통과하여 밸브실(3)을 통과하며 개폐디스크(4)에 고정되어 있는 ㄱ자 스프링(5)에 의해 압력이 저하된 유체는 흐름이 중단되면 역류하는 유체와 ㄱ자 스프링(5)에 의해 개폐 디스크(4)가 원상복구 되어 밸브실을 차단하게 된다. (도면5)According to the present invention, the fluid flowing in the pipe passes through the threaded portion 2, passes through the valve chamber 3, and the fluid whose pressure is reduced by the L-shaped spring 5 fixed to the opening / closing disk 4 is stopped. The opening / closing disk 4 is restored to its original state by the backflowing fluid and the A-shaped spring 5 to block the valve chamber. (Fig. 5)

이와 같은 본 고안의 내용은 첨부된 일실시예로서의 도면을 참조하여 더욱 상세히 설명하며 다음과 같다.Such content of the present invention will be described in more detail with reference to the accompanying drawings as an embodiment and as follows.

도2는 본고안의 내용은 첨부된 일실시예를 나타낸 단면도이며,Figure 2 is a cross-sectional view showing an embodiment of the contents of the present attached,

도3,4,5는 그작용 상태도이며,3, 4, and 5 is a state diagram of the operation,

도6은 다른 실시예의 작용상태도를 나타낸 단면도이다.6 is a cross-sectional view showing an operational state diagram of another embodiment.

일자형 본체(1)와 양쪽의 나사부(2)가 형성되어 있고 밸브실(3)이 형성되어 있다. The straight main body 1 and the threaded part 2 of both sides are formed, and the valve chamber 3 is formed.

밸브실(3)에 통로가 형성되고 이통로를 개폐하는 개폐 디스크(4)가 설치되어 있다. A passage is formed in the valve chamber 3, and the opening / closing disk 4 which opens and closes this passage is provided.

상기 나사부 좌,우는 배관에 연결되며, 상기 밸브실(3)에 설치되는 개폐 디 스크(4)의 상단과 하단 부분에 홈(4-1)(4-2)을 형성시켜 이홈(4-1)(4-2)에 ㄱ자스프링(5)을 끼워 고정핀(6)으로 본체(1)에 끼워 고정볼트(7)로 조립되면, 상기 개폐 디스크(4)는 자체적인 힘으로 통로의 폐쇄가 이루어질수 있으나 개폐 디스크(4)의 홈(4-1)(4-2)에 ㄱ자 스프링(5)이 설치되어 통로쪽으로 탄성바이어스 되도록 함으로써 유체의 압력이 없을 경우에는 항상 통로를 차단되도록 되어 있다.(도면6)The left and right sides of the screw portion are connected to a pipe, and grooves 4-1 and 4-2 are formed in the upper and lower portions of the opening and closing disk 4 installed in the valve chamber 3, thereby forming the groove 4-1. (4-2), the A-shaped spring (5) is inserted into the main body (1) by the fixing pin (6) when assembled into the fixing bolt (7), the opening and closing disk (4) is closed of the passage by its own force It can be made, but the L-shaped spring (5) is installed in the groove (4-1) (4-2) of the opening and closing disk (4) to be elastically biased toward the passage so that the passage is always blocked when there is no pressure of the fluid. Drawing 6)

이에 따라 수직배관 수평배관 어떠한 배관에서도 안정적으로 역류를 차단 할 수 있게된다.As a result, it is possible to stably block backflow in any pipeline.

또한, 과압력으로 인한 개폐 디스크(4)가 벽에 부딪혀 소리가 나는 현상을 개폐 디스크(4) 홈(4-1)(4-2)에 상하로 고정 장착된 ㄱ자 스프링(5)에 의해 압력이 완충되어 그 현상을 막을 수 있다.In addition, the phenomenon that the opening and closing disk 4 due to the overpressure hits the wall and makes a sound by the A-shaped spring 5 fixedly mounted to the opening and closing disk 4 grooves 4-1 and 4-2 up and down This buffer can be prevented.

이상에서 설명하고 도시한 바와 같은 본 고안은, 상기의 실시예에 한정하는 취지는 아니며, 본 고안의 요지를 벗어나지 않는 범위내에서 다양한 형태로 변경 실시 될 수 있을 것이다.The present invention as described and illustrated above is not intended to be limited to the above embodiments, and may be modified in various forms within the scope not departing from the gist of the present invention.

예를들면 본 고안에 ㄱ자스프링(5)은 여러 스프링의 종류와 장착되는 개폐 디스크(4)의 홈(4-1)(4-2)의 갯수, 모양을 얼마든지 변경될 수 있을것이다.For example, the A-spring (5) in the present invention will be able to change the number and shape of the grooves (4-1) (4-2) of the opening and closing disk (4) of the various springs are mounted.

이상에서와 같은 본 고안은 일자형 본체(1)에 양나사부(2)와 밸브실(3)로 형성되며 밸브실(3) 통로를 차단하는 개폐 디스크(4)에 상하로 홈(4-1)(4-2)을 형성시켜 ㄱ자스프링(5)을 고정핀(6)으로 본체(1)에 끼워 고정볼트(7)로 조립되는 구성으로 수평배관 수직배관 어떠한 배관에서도 안정적인 작용을 도모할 수 있는 효과 를 제공한다. The present invention as described above is formed by the two-threaded portion (2) and the valve chamber (3) in the straight body (1) and the groove (4-1) up and down in the opening and closing disk (4) to block the passage of the valve chamber (3) (4-2) is formed by fitting the A-shaped spring (5) to the main body (1) with a fixing pin (6) to be assembled with a fixing bolt (7) horizontal piping vertical piping can achieve a stable operation in any piping Provide effect.

또한 재료 절감효과와 좁은곳에서 배관이 용이하고 유체의 흐름과 관계없이 자동폐되어 역류를 방지한다. 또한 과압력이 발생시 개폐 디스크 홈(4-1)(4-2)에 장착된 ㄱ자 스프링(5)에 의해 차단 완충되어 소리가 나는 현상을 막아준다.In addition, it saves material and makes piping easy in narrow places and prevents backflow by automatically closing regardless of fluid flow. In addition, when the overpressure occurs by the buffer spring (5) mounted on the opening and closing disk groove (4-1) (4-2) to prevent the sound phenomenon.
