본 고안은 소형 압력용기의 체크밸브에 관한 것으로서, 더욱 상세하게는 용기에 체결되는 밸브몸체의 내부로 밸브판의 밸브축을 끼운 뒤 밸브축의 끝단을 벌려서 밸브몸체에 밸브판이 걸리도록 함으로써, 별도의 도구 없이 밸브판을 밸브몸체에 결합할 수 있으므로 구조가 간단하고 조립성이 향상되는 소형 압력용기의 체크밸브에 관한 것이다.The present invention relates to a check valve for a small-sized pressure vessel, and more particularly, to a check valve of a small-sized pressure vessel, in which a valve shaft of a valve plate is inserted into a valve body to be fastened to the vessel, To a check valve of a small-sized pressure vessel in which the valve plate can be coupled to the valve body without a simple structure and the assembling property is improved.

일반적으로 액상의 화장품이나 세제, 모기약과 같은 각종 살충제 등의 내용물을 담은 용기의 개구부에는 디스펜서를 결합하여 내용물을 토출시켜 사용할 수 있도록 하였는데, 이러한 디스펜서로 특허 제1022618호에는 용기의 상단 개구부에 나사결합하는 캡의 상단부에 승강하게 결합설치되며 노즐이 부설된 버튼과 상기 버튼의 하부에 결합하는 스템과 상기 스템의 하단에 결속되며 버튼과 스프링에 의해 실린더의 하우징 내부에서 승강하게 되는 피스톤과 상기 실린더의 하단 개구부를 여닫아주게 내부에 장착되는 볼 형태의 체크밸브를 포함하여 구성되며, 상기 버튼을 누르면 스템과 피스톤이 스프링을 가압하면서 하강하는 과정에서 실린더의 내부에 있는 내용물은 내부압력에 의해 피스톤에 형성된 유입구와 스템의 내부 통로를 거쳐 노즐을 통해 토출되고 상기 체크밸브는 실린더의 개구부를 닫아주게 되며 반대로 버튼을 놓으면 압축되었던 스프링의 탄성에 의해 스템과 피스톤이 상승하고 이 과정에서 체크밸브가 열리게 되므로 용기 내부의 내용물이 실린더로 유입되어 다음 토출을 대기토록 한 것이다.In general, a dispenser is combined with an opening of a container containing contents such as liquid cosmetics, detergents, and various insecticides such as detergents and mosquito repellents so that the contents can be discharged and used. Such a dispenser is disclosed in Japanese Patent No. 1022618, A piston coupled to the upper end of the cap and coupled to the lower end of the stem, a piston coupled to the upper end of the cap and having a nozzle, a stem coupled to a lower portion of the button, a piston coupled to a lower end of the stem, And a check valve in the form of a ball mounted inside the cylinder to close and open the lower opening. When the cylinder is depressed while pushing the button, the contents inside the cylinder are released to the piston Through the formed inlet and the internal passageway of the stem through the nozzle And the check valve closes the opening of the cylinder. On the contrary, when the button is released, the stem and the piston rise due to the elasticity of the spring which has been compressed. Since the check valve is opened in this process, the contents inside the container are introduced into the cylinder, I have to wait.

그러나 종래의 체크밸브는 스프링과 볼의 형태로 구성되고 또한 이들 스프링 및 볼을 잡아주기 위한 구조물이 필요하므로 구조가 복잡한 단점이 있었다.However, the conventional check valve is configured in the form of a spring and a ball, and a structure for catching the spring and the ball is required, so that the structure is complicated.

본 고안은 종래의 문제점을 감안하여 개발한 것으로서, 본 고안의 목적은 용기에 체결되는 밸브몸체의 내부로 밸브판의 밸브축을 끼운 뒤 밸브축의 끝단을 벌려서 밸브몸체에 밸브판이 걸리도록 함으로써, 별도의 도구 없이 밸브판을 밸브몸체에 결합할 수 있으므로 구조가 간단하고 조립성이 향상되는 소형 압력용기의 체크밸브를 제공함에 있다.The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a valve body for an internal combustion engine in which a valve shaft of a valve plate is inserted into a valve body fastened to a container, The valve plate can be coupled to the valve body without a tool, thereby providing a check valve of a small-sized pressure vessel in which the structure is simple and the assembling property is improved.

이를 위하여 본 고안은 소형용기에 나사산을 통하여 체결되는 밸브몸체가 구비되고, 상기 밸브몸체의 통로에 끼워지는 밸브축을 갖는 밸브판은 상기 밸브몸체의 패킹과 밀착되어 한방향으로 액체를 토출하도록 된 소형 압력용기의 체크밸브에 있어서, 상기 밸브축의 끝단은 양쪽으로 걸림턱이 구비되고, 상기 걸림턱들의 사이에 절개부가 형성되며; 상기 밸브몸체의 통로에는 상기 밸브축이 끼워지도록 상기 통로보다 직경이 작은 토출구가 형성되어, 상기 통로에 끼워진 밸브축의 상기 절개부를 양쪽으로 벌리면 상기 걸림턱들이 벌어져서 상기 토출구에 걸린 상태로 상기 밸브판이 상기 밸브몸체에 체결되는 특징이 있다.In order to achieve the above object, the present invention has a valve body which is fastened to a small container through a thread, and a valve plate having a valve shaft fitted in a passage of the valve body is fitted to a packing of the valve body, A check valve of a container, wherein an end of the valve shaft is provided with a stopping jaw on both sides, and a cutout is formed between the stopping jaws; Wherein the valve body is provided with a discharge port having a diameter smaller than that of the passage so that the valve shaft is inserted into the valve body. When the cutout of the valve shaft inserted in the passage is opened to both sides, the engagement protrusions are opened, And is fastened to the valve body.

본 고안은 체크밸브를 구성하는 밸브몸체의 내부로 밸브판의 밸브축을 끼운 뒤 상기 밸브축을 고정하여 밸브판이 밸브몸체에서 분리되지 않도록 하기 위한 것으로서, 종래에는 밸브축을 밸브몸체의 외부로 돌출시켜 고정하였으나 부피가 커서 용기에 체결하는데 번거로웠다.The present invention is intended to prevent the valve plate from being separated from the valve body by inserting the valve shaft of the valve plate into the valve body constituting the check valve and then fixing the valve shaft to the valve body so that the valve shaft is conventionally fixed by being protruded to the outside of the valve body It was bulky and it was troublesome to fasten to the container.

이를 개선하기 위하여 본 고안은 밸브판의 밸브축 끝단을 절개하여 양쪽으로 갈라지도록 하고 갈라진 양단에는 걸림턱을 형성한 것이다. 따라서 밸브축을 밸브몸체의 내부로 끼운 뒤 갈라진 양쪽을 벌려서 상기 걸림턱 사이 간격이 벌어지도록 하면 밸브몸체 내부에서 걸림턱들이 걸려서 밸브판이 밸브몸체에 결합되는 간단한 구성에 의해 별도의 구조물 없이도 밸브판과 밸브몸체를 결합할 수 있으므로 구조가 간단하고 또한 밸브축이 밸브몸체의 외부로 돌출되지 않으므로 부피를 줄일 수 있는 등의 이점이 있다.In order to solve this problem, the present invention is characterized in that the end of the valve shaft of the valve plate is cut so as to be divided into both sides, and the both ends of the valve plate are formed with a stopper. Therefore, when the valve shaft is inserted into the inside of the valve body, and the gap between the engaging jaws is widened by opening the both sides of the valve body, the engagement protrusions are caught in the valve body, and the valve plate is coupled to the valve body. There is an advantage that the structure can be simplified and the valve shaft can not be protruded to the outside of the valve body, so that the volume can be reduced.

도 1 내지 도 3에서 본 고안 한 실시예의 체크밸브는 밸브몸체(10)의 외주면에 나사산(13)이 형성되어 소형용기의 내부에 밸브몸체(10)를 고정시킨다. 그리고 밸브몸체(10)의 내부에는 액체가 흐르는 통로(11)가 형성되고, 상기 통로(11)의 한쪽에는 통로(11)보다 직경이 작은 토출구(12)가 형성된다.1 to 3, the check valve is formed with a thread 13 on the outer peripheral surface of the valve body 10 to fix the valve body 10 inside the small-sized container. A passage 11 through which the liquid flows is formed inside the valve body 10 and a discharge port 12 having a diameter smaller than that of the passage 11 is formed on one side of the passage 11.

상기 밸브몸체(10)의 토출구(12) 쪽에는 밸브판(20)이 구비되는데, 상기 밸브판(20)의 중앙에는 밸브축(21)이 형성되어서 상기 토출구(12)를 따라 상기 통로(11)에 끼워진다. 상기 밸브축(21)은 끝으로 갈수록 직경이 작아진 원추형으로 구성되어 상기 토출구(12)에 상기 밸브축(21)이 끼워진 상태에서 밸브축(21)의 외주면과 상기 토출구(12)의 내주면 사이에 틈새가 벌어져서 액체가 흐를 수 있는 공간을 제공한다.A valve shaft 20 is formed at the center of the valve plate 20 so that the passage 11 is formed along the discharge port 12, . The valve shaft 21 is formed in a conical shape having a smaller diameter toward the end so that the gap between the outer circumferential surface of the valve shaft 21 and the inner circumferential surface of the discharge port 12 in a state in which the valve shaft 21 is fitted in the discharge port 12 Thereby providing a space through which liquid can flow.

그리고 상기 밸브축(21)의 끝단은 절개부(23)에 의해 양쪽으로 갈라진 걸림턱(22)이 형성된다. 또한 상기 밸브몸체(10)의 외주면에는 상기 밸브판(20)과 밀착되는 패킹(14)이 구비된다.The end of the valve stem (21) is formed with an engagement protrusion (22) which is split on both sides by a cutout (23). The valve body (10) is provided on the outer circumferential surface thereof with a packing (14) in close contact with the valve plate (20).

이처럼 구성된 본 고안 한 실시예는 도 2에서와 같이 조립된다. 먼저 밸브판(20)의 밸브축(21)을 토출구(12)에 끼워서 통로(11) 내부로 밀어 넣는다. 이후 통로(11)에 별도의 도구를 집어넣고 상기 절개부(23)를 양쪽으로 벌려서 각 걸림턱(22)이 서로 떨어지도록 해준다. 이때 걸림턱(22)들은 벌어져서 토출구(12)에 걸린 상태로 밸브축(21)이 통로(11)의 내부에 고정된다. 결국 밸브판(20)은 밸브몸체(10)에 걸린 상태로 조립된다.The present inventive embodiment thus constructed is assembled as in Fig. First, the valve shaft (21) of the valve plate (20) is inserted into the discharge port (12) and is pushed into the passage (11). Thereafter, a separate tool is inserted into the passage 11 and the cut-out portion 23 is widened on both sides so that the engagement protrusions 22 are separated from each other. At this time, the stopping jaws 22 are opened and the valve shaft 21 is fixed to the inside of the passage 11 in a state in which the stopping jaws 22 are engaged with the discharge port 12. As a result, the valve plate 20 is assembled with the valve body 10 engaged.

이같은 상태에서 용기에 나사산(13)을 통하여 밸브몸체(10)를 체결하면 용기 내부의 액체 압력에 의해 밸브판(20)이 밀리면서 패킹(14)과 밀착되므로 액체의 누설이 방지된다. 이런 상태에서 통로(11)에 끼워진 막대(미도시)를 누르면 밸브축(21)이 밀리면서 밸브판(20)이 패킹(14)에서 떨어지고 액체가 토출구(12)에서 통로(11)로 빠져나와 외부로 분사된다. 이때 걸림턱(22)은 벌어진 상태이므로 토출구(12)에 걸린 상태를 유지하므로 밸브판(20)이 밸브몸체(10)에서 떨어지는 간격이 일정하게 유지된다.In this state, when the valve body 10 is fastened to the container through the thread 13, the valve plate 20 is pressed by the liquid pressure inside the container and is brought into close contact with the packing 14, so that leakage of the liquid is prevented. In this state, when a rod (not shown) inserted in the passage 11 is pressed, the valve shaft 21 is pushed, the valve plate 20 is separated from the packing 14, and the liquid is discharged from the discharge port 12 to the passage 11 And is sprayed outside. At this time, since the latching jaw 22 is opened, the valve plate 20 is held in the discharge port 12, so that the gap between the valve plate 20 and the valve body 10 is kept constant.
