본 고안은 공기주입 피스톤의 역지밸브에 관한 것이다.The present invention relates to a check valve of the air injection piston.

공기주입 폄프에서 피스톤은 중요한 부분이 된다. 피스톤은 왕복행정을 통하여 절반은 공기주입, 나머지 절반은 외부 공기흡입과정을 수행한다. 여기서 피스톤이 외부 공기를 흡입할때 실린더에는 외부와 연통되어 피스톤의 동작에 대응해서 개폐되는 역지밸브가 필요하게 된다. 통상적으로 이 역지밸브는 실린더 헤드부분에서 외부로 돌출되게 장치된다. 이 때문에 공기주입 펌프는 외형이 커지고, 외부로 노출되는 역지밸브가 외력에 의해 쉽게 파손되어지는 결점이 있었다.The piston is an important part of the air injection pump. The piston carries out half the air injection and half the outside air suction through the reciprocating stroke. Here, when the piston sucks the outside air, the cylinder needs a check valve in communication with the outside to open and close in response to the operation of the piston. Typically this check valve is arranged to protrude outward from the cylinder head portion. For this reason, the air injection pump has a drawback in that its appearance is large, and the check valve exposed to the outside is easily damaged by external force.

본 고안은 상기 결점을 해결하고자 안출된 것으로서 간단한 구조의 역지밸브를 제공하여 피스톤에 장치할 수 있도록 함에 그 목적이 있으며, 이를 첨부 도면에 따라 상세히 설명하면 다음과 같다.The object of the present invention is to provide a check valve having a simple structure, which is devised to solve the above-described drawbacks, and has a purpose to be installed on a piston, which will be described in detail with reference to the accompanying drawings.

도시한 바와 같이 본 고안의 역지밸브는 외주에 나사산(1)이 새겨지고, 내부가 중공상 홉퍼를 이루어 밸브시트(2)를 형성하며, 이 밸브시트(2)로부터 통로(3)이 축방향으로 개설된 몸체(4)와, 전기한 밸브시트(2)에 안치되는 첨두밸브체(5) 및 몸체(4)의 개구단에 씌워지고 중앙에 통공(6)이 뚫려진 마개(7)로 구성된다.As shown, the check valve of the present invention is engraved with a thread (1) on the outer periphery, the inside of the hollow hopper to form a valve seat (2), from which the passage (3) in the axial direction With a stopper 7 having a body 4 opened and a peak valve body 5 placed on the valve seat 2 and an opening end of the body 4 and having a through hole 6 in the center thereof. It is composed.

상술한 구성의 본 고안은 통상적인 공기주입 피스톤P의 평면에 나착되어지는 것으로 피스톤P의 왕복작동시에 발생하는 표리면의 부압발생에 의해 첨두밸브체(5)가 스스로 몸체(4)내의 통로(3)을 개폐해주는 것으로 피스톤P의 공기주입과 흡입이 행해지게 된다.The present invention of the above-described configuration is attached to the plane of the conventional air injection piston P, the peak valve body 5 is a passage in the body 4 itself by the negative pressure generated on the front and back surface generated during the reciprocating operation of the piston P. (3) By opening and closing the piston P air injection and suction is performed.

본 고안에서 밸브의 구조는 지극히 간단하므로 피스톤P에 장치될 수 있을 정도의 소형제작이 가능하고, 이로인하여 종래와 같은 공기주입 펌프에서 역지밸브가 파손되어 못쓰게될 우려가 없어지게 되고, 공기주입 펌프는 외관이 단순하게 제작될 수 있다는 이점을 갖는다.Since the valve structure of the present invention is extremely simple, it is possible to manufacture a small size that can be installed on the piston P, and thus there is no fear that the check valve may be damaged and damaged in the conventional air injection pump. Has the advantage that the appearance can be made simply.
