Abstract
본 고안은 단수 시 역류현상을 방지하는 배관용 체크밸브에 관한 것이다. The present invention relates to a check valve for piping to prevent the backflow phenomenon in the single stage.
종래의 배관용 체크밸브는 이의 공실 내에 힌지 설치된 변판을 끼움 설치하기 위하여 몸체의 중간부에 트임부를 형성하여 이 트임부를 통해 변판을 끼운 다음 마개로서 나사 조임하였기 때문에 제작 상 난점이 있을 뿐만 아니라 정확한 수평 시공이 되지 못할 시는 변판이 밀접되지 않아 누수현상이 생기는 폐단이 있었던 것이다. The conventional pipe check valve has a difficulty in manufacturing as well as a difficulty in manufacturing because a pipe is formed in the middle of the body to install a hinged valve in the vacancy of the pipe. When the construction could not be done, there was a discontinuity caused by leaking phenomenon because the stool was not close.
본 고안은 이상의 문제점을 해결하고자 안출한 것으로, 이의 고안 요지는 몸체(1)의 일측에 나사부(1a)와 끼움부(1b)를 현상하여 이 나사부(1a)에는 연결 몸체(3)의 나사부(3a)가 나사 조임되고, 상기한 끼움부(1b)에는 통공판(2a)이 있는 변판 안내구(2)가 끼움되어 있으되, 이 변판 안내구(2)의 주면에는 일정 간격으로 다수의 지지간(2b)을 개재한 트임부(2c)가 형성되고 그 내부에 형성된 공실(2d) 내에는 스프링(5)을 개재한 변판(4)이 헐겁게 끼움되어 단수 시 역수압을 받으면 변판(4)이 통상 시와는 반대 방향으로 이동하면서 통공부(1c)를 차폐할 수 있게 하였기 때문에 제작 상 간편할 뿐만 아니라 몸체(1)의 시공 시에 있어 정밀한 수평 시공이 되지 않아도 누수현상이 생기지 않아 매우 실용적이다.

The trimming part 2c through (2b) is formed, and the board | plate 4 through the spring 5 is loosely inserted in the vacancy 2d formed in the inside, and when the board | plate receives water pressure in a single stage, the board | plate 4 becomes Since it is possible to shield the through hole 1c while moving in the opposite direction as usual, it is not only simple in manufacturing but also practical because no leakage occurs even when the horizontal construction is not precise in the construction of the body 1. .
Description
본 고안은 배관용 체크밸브에 관한 것이다. The present invention relates to a pipe check valve.
종래의 배관용 체크밸브는 공실 내에 변판을 설치하기 위하여 몸체의 중간부에 트임부를 형성하여 이 트임부를 통해 변판을 끼운 후 나사부가 있는 마개로 밀폐하고 있는 관계로 구조가 복잡하여 제작 상 난점이 있을 뿐만 아니라 정밀한 수평 시공이 아닐 시는 누수현상이 생기는 등 수밀성을 기대할 수 없는 폐단이 있었던 것이다. The conventional pipe check valve has a difficulty in manufacturing due to its complicated structure, since a pipe is formed in the middle of the body in order to install the valve in the vacancy, and the valve is inserted through the valve to be closed with a screw cap. In addition, when there is no precise horizontal construction, water leakage may occur.
본 고안은 이상의 문제점을 해결하고자 안출한 것으로, 이의 고안 요지는 몸체(1)의 일측에 나사부(1a)와 끼움부(1b)를 형성하여 이 끼움부(1b)에는 공실(2d) 내에 스프링(5)을 개재한 변판(4)이 헐겁게 끼움된 변판 안내구(2)가 끼움되고, 상기한 나사부(1a)에는 연결 몸체(3)의 나사부(3a)가 나사 조임됨으로서 제작 상 간편하고 몸체(1)가 경사되게 시공된 조건하에서도 정확한 수밀 작동을 할 수 있게 한 것이다. The present invention is devised to solve the above problems, the subject matter of the present invention is to form a threaded portion (1a) and the fitting portion (1b) on one side of the body (1) to the fitting portion (1b) in the vacancy (2d) spring ( 5) The plate guide (2) through which the side plate (4) is loosely fitted is fitted, and the threaded portion (3a) of the connecting body (3) is screwed into the screw portion (1a), which is simple in manufacture and the body ( It is to enable accurate watertight operation even under the condition that 1) is inclined.
이를 도면에 의거 상세히 설명하면 다음과 같다. This will be described in detail based on the drawings.
몸체(1)의 일측에는 통공부(1c)와 연결 나사부(1d)가 형성되고 타측에는 나사부(1a)와 끼움부(1b)를 형성하되 이 끼움부(1b)에는 통공판(2a)이 있는 변판 안내구(2)가 끼움되고, 변판 안내구(2)의 외주면에는 일정 간격으로 다수의 지지간(2b)을 개재한 트임부(2c)가 형성되고 그 내부에 형성된 공실(2d) 내에는 스프링(5)을 개재한 변판(4)이 헐겁게 끼움되고, 상기한 나사부(1a)에는 연결 몸체(3)의 나사부(3a)가 나사 조임되면서 공실(3d)을 형성하고 그 일측에 형성된 통공부(3b)에는 관체를 이음하는 연결 나사부(3c)가 형성된 것이다. One side of the body 1 is formed with a through hole (1c) and connecting threaded portion (1d) and on the other side to form a threaded portion (1a) and a fitting portion (1b), the fitting portion (1b) has a through plate (2a) The guiding plate 2 is fitted, and on the outer circumferential surface of the guiding plate 2, a trimming portion 2c is formed at a predetermined interval via a plurality of supporting sections 2b, and in the empty space 2d formed therein. The side plate 4 through the spring 5 is loosely fitted, and the threaded portion 3a of the connecting body 3 is screwed onto the threaded portion 1a to form an empty space 3d, and a through hole formed on one side thereof. In (3b), the connection screw part 3c which connects a pipe | tube is formed.
이상과 같이 구성된 본 고안은 단수 시의 역류를 방지하는 배관용 체크밸브인바, 이를 실시할 시는 몸체(1)의 통공부(1c) 및 연결 몸체(3)의 통공부(3b)에 배관용 관체를 나사 조임하면 되는 것으로 통상 시에는 통공부(1c)를 통해 유입된 물의 압력이 변판(4)을 받치고 있는 스프링(5)을 압축하고 내향 이동함에 따라 생기는 공간부 및 통공판(2a) 및 트임부(2c)를 통해 통수되고, 정전 등의 사정으로 송수가 중단되면 이때에는 역류현상이 생기게 된다. 이와 같이 역류현상이 생기면 이때에는 변판(4)이 수압에 의해 앞서와는 반대 방향으로 이동되면서 끼움부(1b)의 통공을 밀폐하게 되므로, 몸체(1)가 경사된 조건하에서도 밀폐가 가능한 것이다. The present invention configured as described above is a check valve for pipes to prevent the reverse flow in the case of a single stage, when performing the pipe for the through hole (1c) and the through hole (3b) of the connecting body (3) of the body (1) It is only necessary to screw the tubular body. Usually, the space and the through-plate 2a generated by the pressure of the water flowing through the through-hole 1c compress and move inwardly of the spring 5 supporting the side plate 4 and If the water is passed through the trimming part 2c and the water supply is stopped due to a power failure or the like, a backflow phenomenon occurs at this time. In this case, when the reverse flow phenomenon occurs, the valve 4 moves in the opposite direction by water pressure to seal the through hole of the fitting portion 1b, so that the body 1 can be sealed even under the inclined condition. .
이상과 같이 본 고안은 몸체(1)의 일측에 나사부(1a)와 끼움부(1b)를 형성하여 이 끼움부(1b)에는 변판 안내구(2)가 끼움되어 있으되, 이 변판 안내구(2)의 선단에는 통공판(2a)이 형성되고 주면에는 일정 간격으로 다수의 지지간(2b)을 개재한 트임부(2c)를 형성하고, 그 내부에 형성된 공실(2d) 내에는 스프링(5)을 개재한 변판(4)을 헐겁게 끼움 설치하고 상기한 나사부(1a)에는 연결 몸체(3)의 나사부(3a)가 나사 조임되게 하였기 때문에 구조가 간편하여 생산원가 절감이 있을 뿐만 아니라 정확한 수평 시공이 되지 않아도 수밀성을 기대할 수 있어 매우 실용적이다. As described above, the present invention forms the threaded portion 1a and the fitting portion 1b on one side of the body 1, and the guiding plate 2 is fitted in the fitting portion 1b, but the guiding plate 2 The perforated plate 2a is formed at the tip of the head), and on the main surface is formed a trimmed portion 2c with a plurality of support intervals 2b at regular intervals, and a spring 5 in the vacant space 2d formed therein. Since the plate 4 interposed therebetween is loosely installed, and the screw portion 3a of the connecting body 3 is screwed into the screw portion 1a, the structure is simple and the production cost is reduced, as well as accurate horizontal construction. It is very practical because it can expect watertightness even if it is not.
