본 고안은 방향전환이 가능한 체크밸브(check valve)에 관한 것으로, 보다 상세하게는 밸브에 형성된 회전축에 의한 인-아웃 포트(in-out port)를 전환가능하게 하여 필요에 따라 회전축을 회전시킴으로써 방향을 자유롭게 설정할 수 있도록 하는 체크밸브에 관한 것이다.The present invention relates to a check valve that can be changed direction, and more particularly, it is possible to switch the in-out port by the rotating shaft formed on the valve to rotate the rotating shaft as necessary It relates to a check valve that can be set freely.

일반적으로 체크밸브는 유압 또는 공압을 한 방향으로 흐르게 하는 밸브로서, 이는 체크(check)를 위한 수단으로 포핏(popet)이 내장되어 입구로 들어간 유압 또는 공압이 스프링의 작용에 의하여 포핏을 눌러 유압 등이 출구를 통하여 빠져나가게 된다. 포핏과 시이트의 닫는 면은 정밀가공되어 있어 출구의 압력이 입구의 압력보다 높아지면 닿는 면이 밀착되므로 체크밸브는 역류를 방지하여 한쪽 방향으로만 흐르도록 되어 있다.In general, the check valve is a valve that flows hydraulic pressure or pneumatic in one direction, and a poppet is built as a means for checking, and the hydraulic pressure or pneumatic pressure entering the inlet presses the poppet by the action of the spring, and so on. Exit through this exit. The closing surface of the poppet and the sheet is precisely processed. When the outlet pressure is higher than the inlet pressure, the contact surface is in close contact. Therefore, the check valve prevents backflow and flows in only one direction.

이러한 한쪽 방향으로만 흐르도록 한 체크밸브는 인-아웃 포트, 즉 입구와 출구가 이미 설정되어 제작됨으로 역방향으로 흐름이 불가능하다. 때문에 역방향으로의 흐름이 필요한 경우에는 조립된 밸브를 분리시켜 이를 거꾸로 하여 다시 조립해야 하는 번거로움이 있다. 따라서 역방향으로 유로를 변경하거나 상황에 따라 수시로 변경시켜야 되는 조건에서는 상기와 같은 체크밸브의 사용이 곤란해지는 문제점이 있는 것이다.The check valve that is allowed to flow in only one direction cannot be flowed in the reverse direction because the in-out port, that is, the inlet and the outlet is already set and manufactured. Therefore, if the flow in the reverse direction is required to remove the assembled valve, it is inconvenient to reassemble it. Therefore, there is a problem in that the use of the check valve as described above is difficult under conditions that should change the flow path in the reverse direction or change from time to time according to the situation.

본 고안은 상기의 문제점을 감안하여 창안한 것으로, 회전축에 내장된 통상의 체크를 위한 포핏을 내장시켜 회전축을 회전시킴에 따라 유로의 방향을 전환 할 수 있게 하여 상황에 따라 유로를 신속하게 전환시킬 수 있게 하는 방향전환이 가능한 체크밸브를 제공하는데 그 목적이 있다.The present invention was devised in view of the above-mentioned problems, and built-in poppet for normal check built in the rotating shaft enables the flow path to be changed quickly depending on the situation by rotating the rotating shaft. It is an object of the present invention to provide a reversible check valve.

본고안은 상기의 목적을 달성하기 위한 구체적인 수단으로 회전축에 체크를 위한 포핏을 내장한 회전축을 보디에 나사결합되는 고정축의 중공부를 통해 회전가능하게 설치하고, 고정축의 상면 양측으로 대향되게 위치결정용 안내핀을 인서트하여 회전축에 연결된 핸들을 180° 회동시켜 회전축에 내장된 포핏의 방향이 전환되어 유로의 흐름을 전환할 수 있게 한 것이다.The present invention is a concrete means for achieving the above object by installing a rotary shaft with a poppet for checking on the rotary shaft rotatably through the hollow portion of the fixed shaft which is screwed to the body, for positioning positioning opposite to the upper surface of the fixed shaft By inserting the guide pin, the handle connected to the rotating shaft is rotated 180 ° so that the direction of the poppet embedded in the rotating shaft is changed to change the flow of the flow path.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의거 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안의 체크밸브(10)를 단면도로 도시한 것이다. 보디(12)의 중심부에 나사부(14)가 형성되고 나사부(14)의 하부로 구멍(16)이 형성되며, 구멍(16)의 양측으로 유로공(18)이 형성된다. 그리고 보디(12)에 설치되는 회전축(20)은 작은 지름을 갖는 축(20A)과 이 축(20A)보다 상대적으로 지름이 큰 축(20B)으로 이루어지며, 상기 축(20A)에 단턱을 형성하여 오링(22)을 개재하고, 축(20B)에는 상기 유로공(18)의 지름과 같은 유로공(24)을 형성하고, 이 유로공(24)의 중앙에는 체크를 위한 포핏(26)을 형성하여 이루어진 회전축(20)을 상기 보디(12)에 형성된 구멍(16)에 삽입하고, 이 회전축(20)의 축(20A)을 통해 중공부(30)가 형성된 고정축(28)을 삽입하여 고정축(28)에 형성된 나사부(32)를 보디(12)에 형성된 나사부(14)에 나사고정한다. 그리고 상기 축(20A)의 상부에 핸들(34)을 결합하고, 이 핸들(34)이 고정축(28)의상면에 대향되어 인서트된 위치결정용 안내핀(36)에 의해 회전축(20)을 180°로 회전가능하게 하여 회전축(20)내에 내장된 포핏(26)에 의해 유로가 변환되게 구성한 것이다. 도면중 미 설명부호 28은 시이트, 40은 스프링을 도시한 것이다.1 is a cross-sectional view of the check valve 10 of the present invention. A screw portion 14 is formed at the center of the body 12, a hole 16 is formed below the screw portion 14, and flow path holes 18 are formed at both sides of the hole 16. In addition, the rotating shaft 20 installed in the body 12 is composed of a shaft 20A having a small diameter and a shaft 20B having a larger diameter than the shaft 20A, and forming a step in the shaft 20A. Through the O-ring 22, the shaft 20B is formed with a flow path hole 24 equal to the diameter of the flow path hole 18, and a poppet 26 for checking is formed at the center of the flow path hole 24. The rotating shaft 20 formed is inserted into the hole 16 formed in the body 12, and the fixed shaft 28 having the hollow portion 30 is inserted through the shaft 20A of the rotating shaft 20. The screw portion 32 formed on the fixed shaft 28 is screwed to the screw portion 14 formed on the body 12. Then, the handle 34 is coupled to the upper portion of the shaft 20A, and the handle 34 is rotated by the positioning guide pin 36 inserted to face the upper surface of the fixed shaft 28. The flow path is converted by the poppet 26 embedded in the rotation shaft 20 so as to be rotatable at 180 °. In the drawings, reference numeral 28 denotes a sheet and 40 denotes a spring.

이와 같이 구성된 본 고안의 실시예에 따르면 제1도는 유로공(18,24)의 유압의 흐름이 A방향에서 B방향으로 된 것으로, 이는 제2a도와 같다. 이와 같은 상태에서 유압의 흐름을 B방향에서 A방향으로 전환시키려면, 핸들(34)을 회동시켜 이 핸들(34)과 결합된 회전축(20)이 회전되면서 고정축(28)에 형성된 위치결정용 안내핀(36)에 의하여 회전축(20)은 180° 회전하여 멈추게 된다. 따라서 제2b도와 같이 유로의 방향이 전환되어 포핏(26)의 작용에 의하여 유압이 B에서 A방향으로 흐르게 되는 것이다.According to the embodiment of the present invention configured as described above in FIG. 1, the flow of hydraulic pressure in the flow path holes 18 and 24 is from the A direction to the B direction, which is the same as that of FIG. In such a state, in order to switch the flow of hydraulic pressure from the B direction to the A direction, the handle 34 is rotated and the rotating shaft 20 coupled with the handle 34 is rotated for positioning formed on the fixed shaft 28. The rotating shaft 20 is stopped by rotating the shaft 180 by the guide pin 36. Therefore, as shown in FIG. 2B, the direction of the flow path is switched so that hydraulic pressure flows from the B to the A direction by the action of the poppet 26.

상기와 같은 작용은 핸들(34)의 조작에 의하여 신속하게 유압의 방향을 전환시킬 수 있게 되는 것이다.The above operation is to be able to quickly change the direction of the hydraulic pressure by the operation of the handle (34).

이상에서와 같이 본고안에 의한 체크밸브는 유로방향의 전환이 핸들에 의해 신속하게 이루어져 종래의 한 방향으로 흐르는 체크밸브에 비하면 그 용도를 확대적용 할 수 있을 뿐만 아니라 그 구조가 간단하여 사용하기에 편리하고 제작비용이 저렴한 등의 효과를 갖는 것이다.As described above, the check valve according to the present invention has a quick changeover of the flow path by the handle, which can be used more conveniently than the conventional check valve flowing in one direction, and its structure is simple and convenient to use. And the production cost is low.
