도 1은 본 발명의 분리사시도이고, 도 2는 본 발명의 측단면도이다.FIG. 1 is an exploded perspective view of the present invention, and FIG. 2 is a side sectional view of the present invention.

본 발명 체크밸브 구조(100)는, 제1밸브몸체(120), 제2밸브몸체(130), 제1개폐부재(140), 제2개폐부재(150)으로 구성된다.The check valve structure 100 of the present invention is composed of a first valve body 120, a second valve body 130, a first opening and closing member 140, and a second opening and closing member 150.

상기 제1밸브몸체(120)는 제1부재(10)의 설치공(11)에 고정되며, 상기 설치공(11)과 연통되도록 통공(121)이 형성되고, 내측 상,하부에는 제1개폐부재(140)와 제2개폐부재(150)가 회전가능하게 결합되도록 축홈(122)이 각각 형성된다.The first valve body 120 is fixed to an installation hole 11 of the first member 10 and a through hole 121 is formed so as to communicate with the installation hole 11, An axial groove 122 is formed to allow the member 140 and the second opening and closing member 150 to be rotatably engaged.

또한, 제2밸브몸체(130)는 제1밸브몸체(120)에 결합되어 스크류를 통해 고정되며, 제1,2밸브몸체(120)(130) 사이에는 패킹이 장착되어 누수를 방지하게 된다.The second valve body 130 is fixed to the first valve body 120 through a screw and a packing is installed between the first and second valve bodies 120 and 130 to prevent water leakage.

상기 제2밸브몸체(130)의 하부에는 배출안내공(131)이 형성되고, 상기 배출안내공(131)과 직교되도록 배출공(132)이 형성되어 서로 연통된다.A discharge guide hole 131 is formed in a lower portion of the second valve body 130 and a discharge hole 132 is formed to communicate with the discharge guide hole 131 so as to be perpendicular to the discharge guide hole 131.

상기 제1밸브몸체(120)에 형성된 축홈(122) 중 하부에 형성된 축홈(122)에는 제1개폐부재(140)의 회전축(141)이 회전 가능하게 결합된다.The rotary shaft 141 of the first opening and closing member 140 is rotatably coupled to the shaft groove 122 formed in the lower portion of the shaft groove 122 formed in the first valve body 120.

상기 제1개폐부재(140)의 일측에는 배출안내공(131)을 긴밀하게 폐쇄하도록 실링부재(143)가 장착되고, 타측에는 회전제어돌기(142)가 돌출형성된다.A sealing member 143 is mounted on one side of the first opening and closing member 140 to closely close the discharge guide hole 131 and a rotation control protrusion 142 is protruded from the other side.

또한, 제1밸브몸체(120)에 형성된 축홈(122) 중 상부에 형성된 축홈(122)에는 제2개폐부재(150)의 회전축(151)이 회전 가능하게 결합된다.The rotary shaft 151 of the second opening and closing member 150 is rotatably coupled to the shaft groove 122 formed in the upper portion of the shaft groove 122 formed in the first valve body 120.

상기 제2개폐부재(150)의 일측에는 통공(121)을 긴밀하게 폐쇄하도록 실링부재(153)가 장착되고, 타측에는 회전제어돌기(152)가 돌출형성된다.A sealing member 153 is mounted on one side of the second opening and closing member 150 to closely close the through hole 121 and a rotation control protrusion 152 protrudes from the other side.

또한, 상기 제1밸브몸체(120)의 내부에는 제1,2개폐부재(140)(150)의 회전을 제어하는 스토퍼(160)가 돌출형성되며, 상기 스토퍼(160)는 제1,2개폐부재 (140)(150)에 가해지는 압력이 해제될 경우 자중에 의해 회전할 수 있도록 일정 각도 경사지게 형성되는 것이 바람직하다.A stopper 160 for controlling the rotation of the first and second opening and closing members 140 and 150 protrudes from the first valve body 120, When the pressure applied to the members 140 and 150 is released, it is formed to be inclined at a predetermined angle so as to be rotated by its own weight.

상기와 같이 구성되는 본 발명 체크밸브 구조(100)의 작동상태를 상세하게 설명하면 다음과 같다.The operation state of the check valve structure 100 constructed as above will be described in detail as follows.

먼저, 유입관(20)을 통해 유체가 배출되면, 도 3에 도시된 바와 같이, 유체의 압력으로 제1개폐부재(140)의 하부를 가압하게 됨과 동시에 제1개폐부재(140)의 회전축(141)은 축홈(122)을 중심으로 상향 회전하게 되고, 회전제어돌기(142)는 일정 각도 경사지게 형성된 스토퍼(160)에 밀착되면서 배출안내공(131)을 개방하게 된다.3, when the fluid is discharged through the inlet pipe 20, the lower portion of the first opening and closing member 140 is pressed by the pressure of the fluid, and at the same time, the rotating shaft of the first opening and closing member 140 The rotation control protrusion 142 is brought into close contact with the stopper 160 formed at a predetermined angle and opens the discharge guide hole 131.

이때, 제2밸브몸체(130) 내부로 유입되는 유체의 압력에 의해 제2개폐부재(150)는 축홈(122)을 중심으로 회전하면서 실링부재(153)가 통공(121)을 폐쇄하여 유체가 통공(121)을 통해 제1부재(10) 측으로는 배출되지 않으면서 배출공(132)을 통해 배출관(30)으로만 배출된다.At this time, due to the pressure of the fluid flowing into the second valve body 130, the second opening and closing member 150 rotates about the shaft groove 122 and the sealing member 153 closes the through hole 121, Is discharged to the discharge pipe (30) through the discharge hole (132) without being discharged toward the first member (10) through the through hole (121).

상기 유체의 배출이 완료되면, 스토퍼(160)에 밀착된 제1개폐부재(140)가 자중에 의해 하강 회전하여 배출안내공(131)을 폐쇄하게 된다.When the discharge of the fluid is completed, the first opening / closing member 140 closely attached to the stopper 160 is lowered and rotated by its own weight to close the discharge guide hole 131.

또한, 제1부재(10) 측에서 유체의 오버플로우 현상이 발생할 경우, 도 4에 도시된 바와 같이, 상기 유체는 통공(121)을 통해 유입되어 제2개폐부재(150)의 일측을 가압하게 됨과 동시에 제2개폐부재(150)는 축홈(122)을 중심으로 상향 회전하게 되고, 회전제어돌기(152)는 일정 각도 경사지게 형성된 스토퍼(160)에 밀착되면서 통공(121)을 개방하게 된다.4, when the fluid overflows on the side of the first member 10, the fluid flows into the through hole 121 and presses one side of the second opening and closing member 150 The second opening and closing member 150 is rotated upwards about the shaft groove 122 and the rotation control protrusion 152 is brought into close contact with the stopper 160 formed at a predetermined angle to open the through hole 121.

이때, 제2밸브몸체(130) 내부로 유입되는 유체의 압력에 의해 제1개폐부재(140)는 축홈(122)을 중심으로 회전하면서 실링부재(143)가 배출안내공(131)을 폐쇄하여 유체가 배출안내공(131)으로는 배출되지 않으면서 배출공(132)을 통해 배출관(30)으로만 배출된다.At this time, the first opening / closing member 140 is rotated about the shaft groove 122 by the pressure of the fluid flowing into the second valve body 130, and the sealing member 143 closes the discharge guide hole 131 The fluid is discharged only to the discharge pipe 30 through the discharge hole 132 without being discharged to the discharge guide hole 131.

상기 유체의 배출이 중지되면, 스토퍼(160)에 밀착된 제2개폐부재(150)가 자중에 의해 하강 회전하여 통공(121)을 폐쇄하게 된다.When the discharge of the fluid is stopped, the second opening and closing member 150 which is in close contact with the stopper 160 is lowered and rotated by its own weight to close the through hole 121.

또한, 상기 배출관(30) 측에서 역류가 발생할 경우, 도 5에 도시된 바와 같이, 상기 유체는 배출관(30)과 배출공(132)을 통해 제2밸브몸체(130)의 내부로 유입된다.5, the fluid flows into the interior of the second valve body 130 through the discharge pipe 30 and the discharge hole 132. In addition, as shown in FIG.

이때, 상기 유체의 압력에 의해 제1개폐부재(140)와 제2개폐부재(150)는 축홈(122)을 중심으로 회전하여 실링부재(143)(153)가 배출안내공(131)과 통공(121)에 긴밀하게 밀착되어 유체가 통공(121)과 배출안내공(131)으로 배출되지 않게 되므로 체크밸브의 구조를 간소화하면서 안정성을 확보할 수 있게 된다.The first and second openable and closable members 140 and 150 are rotated about the axial grooves 122 by the pressure of the fluid so that the sealing members 143 and 153 are pushed through the discharge guide hole 131, Since the fluid is not tightly adhered to the through hole 121 and the discharge guide hole 131, the structure of the check valve can be simplified and stability can be ensured.

상기 본 발명 체크밸브 구조(100)는 유체를 기준으로 설명하였으나 이에 한정하는 것은 아니며, 유체 이외에 공기흐름을 제어하는 기술에도 적용될 수 있다.The check valve structure 100 of the present invention has been described with reference to a fluid, but the present invention is not limited thereto. The check valve structure 100 may be applied to a technique of controlling an air flow in addition to a fluid.
