본 고안은 스윙체크 밸브에 관한 것이다.The present invention relates to a swing check valve.
종래의 스윙체크 밸브로서는 밸브 하우징의 밸브시이트에 인접하는 한측면에 피버트 공을 형성하고 이 피버트 공에 원판형의 밸브판의 한쪽연부에 부착되어 있는 피버트 공을 정열시켜서 이들 사이를 피버트 축에 의하여 연결함으로써 밸브판이 수압 또는 기압에 의하여 피버트 축을 중심으로 선회됨으로써 개방되며 또한 밀폐되도록 구성되는 것이다.As a conventional swing check valve, a fever ball is formed on one side adjacent to the valve seat of the valve housing, and the fever ball attached to one edge of the disk-shaped valve plate is aligned with the fever ball. By connecting by the butt shaft, the valve plate is configured to be opened and closed by pivoting about the pivot shaft by hydraulic or air pressure.
상기 종래의 스윙체크 밸브는 다음과 같은 결점들이 있었다.The conventional swing check valve has the following drawbacks.
가) 밸브 시이트와 밸브판사이의 밀착도가 정확하지 못함으로서 밀봉도가 낮아진다.A) The sealing degree is lowered because the adhesion between the valve seat and the valve plate is not accurate.
나) 밸브 시이트와 밸브판의 접촉부 (밸브부)의 연마 가공에 고도의 기술을 요한다.B) Advanced technology is required for the polishing of the valve seat and the contact portion (valve) of the valve plate.
다) 밸브판이 피버트 축을 중심으로 선회되어 개방되므로 밸브를 통과하는 유로가 한쪽으로 치우쳐 지므로 피버트축이 있는 곳과 피버트 축으로부터 먼 곳의 유속에 차이가 생기므로 피버트 축으로 부터 먼 곳의 밸브시이트 면에 마모가 심하여 체크밸브의 수명을 저하시킨다.C) Since the valve plate is pivoted about the pivot shaft and opened, the flow path passing through the valve is biased to one side, so the flow velocity is different from where the pivot shaft is located and far from the pivot shaft, so it is far from the pivot shaft. The wear on the valve seat surface of the valve may be severe and reduce the life of the check valve.
라) 밸브판이 피버트 축을 중심으로 개폐되며 밸브판이 완전 개방되었을때는 밸브판의 끝부가 밸브 하우징의 상부벽면에 충돌된다. 따라서 충돌음을 발생하게 된다.D) The valve plate is opened and closed about the pivot shaft, and when the valve plate is fully open, the end of the valve plate collides with the upper wall surface of the valve housing. Therefore, a collision sound is generated.
특히 펌프에 서어징 형상이 생긴다든가 또는 기타 원인에 의하여 펌프 유속에 맥동 현상이 생기게 되면 이로 말미암아 밸브판에 진동을 발생시켜서 상기 충돌옴이 다발성 충돌음으로 발전됨으로써 매우 소란한 소음을 발생시켜 소음 공해의 원인이 된다.In particular, if the pump has a surge shape or a pulsation phenomenon in the pump flow rate due to other causes, vibrations are generated in the valve plate, thereby generating a very disturbing noise due to the development of the crash noise into multiple impact sounds. Cause.
본 고안은 상기와 같은 종래 스윙 체크밸브에 있어서의 결점을 개선하여 수명이 길고 소음의 발생이 전혀 없는 개량된 스윙체크 밸브를 제공하는 것을 목적으로 하며, 이하 첨부 도면을 참조하여 본 고안은 실시예에 의거하여 상세하게 설명하고저 한다.The object of the present invention is to provide an improved swing check valve having a long service life and no generation of noise by improving the drawbacks of the conventional swing check valve as described above. According to the description in detail.
도면에는 본 고안의 스윙 체크 밸브의 분해사시도와 그 조립 단면도가 표시되어있다.In the drawings, an exploded perspective view and an assembly cross-sectional view of the swing check valve of the present invention are shown.
도면에서 밸브하우징 (1)은 중앙이 볼록하고 양단이 개구된 통형제로 구성되며, 양단에 플랜지(11)가 형성되어 있으나, 이는 한정되는 것이 아니다. 그리고 도면에서 하측개구의 내면에 나사홈으로된 결합부 (12)가 형성되어 있으나 이는 밸브몸체 (2)의 결합부 (22)를 결합시키기 위한 수단이며, 이 수단을 확경 (擴俓)된 턱부로 형성하여 헐겁게 끼워마추는 형식으로 하여도 가능하므로 이 역시 한정되는 것이 아니다.In the figure, the valve housing 1 is composed of a cylindrical member which is convex at the center and opened at both ends, and flanges 11 are formed at both ends, but this is not limited. In the drawing, a coupling part 12 formed of a screw groove is formed on the inner surface of the lower opening, which is a means for engaging the coupling part 22 of the valve body 2, and this means is a jaw enlarged. It is also possible to form in the form of loose fitting and loosely so this is not limited.
밸브몸체 (2)는 결합부 (22)를 가진 통부 (21)와 밸브시이트면 (26)을 가진 밸브시이트부 (23)가 일체로 형성되며 통부 (21)보다 밸브 시이트부 (23)의 직경이 소경으로 형성됨으로써 이들 사이에 턱 (25)이 형성되는 연합 원통형으로 한다.The valve body 2 is integrally formed with a cylinder portion 21 having a coupling portion 22 and a valve seat portion 23 having a valve seat surface 26 and a diameter of the valve sheet portion 23 than the cylinder portion 21. By forming it with this small diameter, it is set as the associated cylinder by which the tuck 25 is formed between them.
밸브 시이트부 (23)를 소경으로하는 것은 다음에 설명할 안내부 (7)가 밸브 시이트부 (23)에 결합되었을때에도 볼트 (8)의 머리부가 상기 턱 (25)의 외경보다 내측으로 위치하게 함으로써 밸브를 하우징에 결합할시에 용이하게 밸브를 하우징 내에 삽입할수 있도록 하기 위한 위함이다.The small diameter of the valve seat 23 is such that the head of the bolt 8 is located inward of the outer diameter of the jaw 25 even when the guide 7 to be described later is coupled to the valve seat 23. This allows for easy insertion of the valve into the housing when the valve is coupled to the housing.
밸브 시이트부 (23)의 원통면에는 직경 방향의 서로 대향 위치의 적소에 안내부 (7)를 조립하기 위한 한쌍의 볼트 구멍 (24)에 천공된다. 밸브 시이트면 (26)과 밸브 시이트부 (23)의 원통면 사이는 경사 곡면으로 절제함으로써 밸브 시이트면 (26)이 좁은 링 형상으로 되게 가공하여 밸브판 (3)에 부착된 테프론 팩킹 (6)과의 접촉이 양호하게 하는 구조로 한다.The cylindrical surface of the valve seat portion 23 is drilled through a pair of bolt holes 24 for assembling the guide portion 7 in place at opposite positions in the radial direction. Between the valve seat surface 26 and the cylindrical surface of the valve seat portion 23, the valve seat surface 26 is processed into a narrow ring shape by ablation to an inclined curved surface to attach the Teflon packing 6 attached to the valve plate 3. It is set as the structure which makes contact with favorable.
도면에서 9는 링 팩킹이며, 반드시 부착할 필요는 없다.9 in the figure is ring packing and need not necessarily be attached.
밸브판 (3)은 원판부의 외경이 밸브 시이트부 (23)의 원통부 외경과 대략 동일치수를 갖도록하며 밸브시이트면 (26)과 대향하는 밸브면에 동심원의 각형링홈을 형성하여 이 홈안에 테프론 제의 각형 환상링의 팩킹 (6)을 삽입한다. 그리고 이 링 팩킹 (6)이 삽입된 내측면에는 팽이 모양의 돌출부 (31)를 형성하여 유기체가 균등하게 밸브면을 통과할수 있도록 배려한다. 그리고 상기 밸브면의 반대면에는 그 중심부에 소정 길이 안내봉 (4)이 밸브판 (3)에 수직으로 일체 형성되며, 동시에 이 안내봉 (4)과 밸브판 (3)의 접속부에는 환상홈 (32)을 형성하여 스프링 좌를 제공하게 된다. 그리하여 코일스프링 (5)을 이 안내봉 (4)외부에 끼우게 된다.The valve plate 3 has an outer diameter of the disc portion approximately the same as the outer diameter of the cylindrical portion of the valve seat 23, and forms a concentric circular ring groove on the valve surface facing the valve seat surface 26 to form a Teflon in the groove. The packing 6 of the first square annular ring is inserted. In addition, the inner surface of the ring packing 6 is inserted to form a top-shaped protrusion 31 so that the organisms can pass evenly through the valve surface. On the opposite side of the valve surface, a predetermined length guide rod 4 is integrally formed at the center thereof perpendicularly to the valve plate 3, and at the same time, an annular groove is formed in the connection portion between the guide rod 4 and the valve plate 3; 32) to provide a spring seat. Thus, the coil spring 5 is fitted outside the guide rod 4.
안내 프레임 (7)은 상부판 (72)과 양다리판 (71)에 의하여 ㄷ자형으로 구성된다. 양 다리판 (71)은 서로 평행이고 그 간격을 밸브시이트부 (23)의 원통부 외경과 같게하여 이 양다리판 (71)이 상기 원통부 또는 밸브판 (3)의 외주와 동일한 곡면으로 형성됨으로써 이들 다리판 (71)사이에서 밸브판 (3)이 끼워져서 이들 다리판에 안내되어 접동됨므로써 밸브작용을 하게된다.The guide frame 7 is formed in a U shape by the top plate 72 and the two legs 71. Both leg plates 71 are parallel to each other and the distance thereof is equal to the outer diameter of the cylindrical portion of the valve seat 23 so that the two leg plates 71 are formed in the same curved surface as the outer circumference of the cylindrical portion or the valve plate 3. The valve plate 3 is sandwiched between these leg plates 71 and guided and slid to these leg plates to act as a valve.
이 다리부 (71)는 끝부의 적소에 볼트 구멍 (77)이 형서되어 이 볼트 구멍(77)과 밸브 시이트부 (23)에 있는 볼트 구멍 (24)에 의해 볼트 (8)를 조립하도록 되어 있다. 그리고 상부판(72)의 중앙에는 안내구멍 (73)이 천공되어 있어 이 구멍을 통하여 밸브판 (3)에 부착되어 있는 안내봉 (4)이 끼워져서 활동할수 있도록 되어 있다.The leg portion 71 is formed with a bolt hole 77 in place at the end portion, so that the bolt 8 is assembled by the bolt hole 77 and the bolt hole 24 in the valve seat portion 23. . In the center of the upper plate 72, a guide hole 73 is drilled so that the guide rod 4 attached to the valve plate 3 can be inserted through the hole to act.
상기와 같이 형성된 밸브몸체 (2), 밸브판 (3), 코일스프링 (5) 및 안내프레임 (7)을 조립하여 형성되는 스윙체크 밸브를 밸브하우징 (1)내에 조립하게되면 제2도 및 제3도의 단면 형상과 같아진다.When the swing check valve formed by assembling the valve body 2, the valve plate 3, the coil spring 5, and the guide frame 7 formed as described above in the valve housing 1 is shown in FIGS. It becomes the same as the cross-sectional shape of 3 degrees.
그리하여 평상시에는 스프링 장력과 장치내의 압력에 의하여 제2도와 같이 밸브가 폐쇄상태로 있게 되며, 표시없는 펌프가 가동되거나 압축 공기가 송기되면 가동유체 압력에 의하여 밸브가 스프링 압력에 항거하여 개방됨으로써 유체가 제3도에서 화살표로 표시한 바와 같이 밸브면에 균등하게 퍼지면서 유출하게 되며, 종래 기술에서와 같은 결함이 없이 우수한 성능과 원활한 동작을 가지고 체크 밸브를 통과하게 되는 것이다.Thus, normally, the valve is closed by the spring tension and the pressure in the device as shown in FIG. 2, and when the pump is operated without an indication or the compressed air is blown, the valve is opened against the spring pressure by the operating fluid pressure. As shown by the arrow in FIG. 3, it will flow out evenly on the valve face, and pass through the check valve with excellent performance and smooth operation without a defect as in the prior art.
