수돗물 등과 같은 유체가 흐르는 관체의 중간부에 구비되어 유체의 흐름을 제어하는데 버터플라이밸브가 주로 사용된다. A butterfly valve is mainly used to control the flow of fluid by being provided in the middle of a pipe through which a fluid such as tap water flows.

버터플라이 밸브는 몸체 중심의 원판 형상의 디스크가 유로에 직각인 축을 회전축으로 90°회전하여 유로를 개폐하면서 유량을 조절하는 방식의 밸브이다. The butterfly valve is a valve in which a disk-shaped disk in the center of the body rotates 90° on an axis perpendicular to the flow path, opening and closing the flow path, and controlling the flow rate.

버터플라이 밸브는 관체에 대응되도록 구성된 단관형태의 밸브본체과, 밸브본체에 회전가능하게 결합된 밸브체로 구성된다.The butterfly valve is composed of a single-pipe valve body configured to correspond to the pipe body and a valve body rotatably coupled to the valve body.

밸브본체의 내주면에는 밸브시트가 형성되며, 밸브본체의 둘레부에는 축받이가 구비된다.A valve seat is formed on the inner circumferential surface of the valve body, and a bearing is provided on the circumference of the valve body.

밸브체는 밸브본체의 내부에 구비되는 디스크와, 축받이에 회전가능하게 결합되며 디스크에 연결되어 디스크가 밸브본체의 내부에 회전되도록 지지하는 밸브스템으로 구성된다.The valve body is composed of a disk provided inside the valve body, and a valve stem that is rotatably coupled to a bearing and connected to the disk to support the disk to rotate inside the valve body.

이때 밸브스템의 일단은 축받이를 통해 밸브본체의 외측으로 연장되며, 그 단부에는 구동용 조작기가 결합된다.At this time, one end of the valve stem extends to the outside of the valve body through a bearing, and a driving manipulator is coupled to the end thereof.

따라서 구동용 조작기를 통해 밸브스템을 회전시키면 디스크가 밸브시트에 밀착되거나 밸브시트에서 이격되면서 밸브본체을 통과하는 유체의 흐름을 제어하게 된다.Therefore, when the valve stem is rotated through the actuator for driving, the disk is in close contact with the valve seat or separated from the valve seat to control the flow of the fluid passing through the valve body.

따라서 부싱(164)이 밸브스템(400)의 외면에 결합됨으로써 밸브스템(400)의 회전 동작을 원활하게 지지해줄 수 있고, 휨을 방지하는 지지력을 발휘할 수 있다. Accordingly, the bushing 164 is coupled to the outer surface of the valve stem 400 to smoothly support the rotational motion of the valve stem 400 and may exhibit a support force to prevent bending.

한편 하우징(180)의 전면판(184)에 밀착 지지되며 밸브스템(400)이 관통하여 결합되도록 하는 커버브래킷(170);을 더 포함한다. Meanwhile, a cover bracket 170 that is closely supported to the front plate 184 of the housing 180 and allows the valve stem 400 to pass therethrough and be coupled; further includes.

커버브래킷(170)은 하우징(180)의 전면판(184)에 밀착되는 지지편(172)이 양측에 형성되어 각 지지편(172)이 전면판(184)에 밀착된 후 나사결합으로 부착된다. The cover bracket 170 has support pieces 172 in close contact with the front plate 184 of the housing 180 formed on both sides, so that each support piece 172 is in close contact with the front plate 184 and then attached by screwing. .

커버브래킷(170)은 외부 충격으로부터 밸브스템(400)을 보호할 수 있게 된다. The cover bracket 170 can protect the valve stem 400 from external impact.

한편 밸브본체(100)의 내주면에 결합되어 디스크(200)의 외주면과 밀착됨으로써 기밀성을 갖도록 하고 부식을 방지하도록 하는 방수커버(500);를 더 포함한다.Meanwhile, a waterproof cover 500 that is coupled to the inner circumferential surface of the valve body 100 and is in close contact with the outer circumferential surface of the disk 200 so as to have airtightness and prevent corrosion; further includes.

방수커버(500)는 밸브본체(120)의 내주면에 결합되며 밸브스템(400)이 관통하도록 통공이 형성된 벽면부(520)와, 벽면부(520)의 상,하단이 외향 절곡되어 밸브본체(120)과 플랜지(140)를 덮도록 결합되는 리브(540)를 포함한다. The waterproof cover 500 is coupled to the inner circumferential surface of the valve body 120 and has a wall surface portion 520 formed with a through hole so that the valve stem 400 penetrates, and the upper and lower ends of the wall surface portion 520 are bent outwardly to the valve body ( It includes a rib 540 coupled to cover the 120 and the flange 140.

따라서 방수커버(500)의 벽면부(520)는 디스크(200)가 닫혔을때 밀폐력을 제공하도록 탄성을 가지면서 유체에 대한 내부식성을 갖는 소재로 이루어짐이 바람직하다. Therefore, the wall portion 520 of the waterproof cover 500 is preferably made of a material having elasticity and corrosion resistance to fluid so as to provide a sealing force when the disk 200 is closed.

바람직하게는 방수커버(500)는 탄성을 갖는 소재로 이루어지며, 고무 또는 우레탄, 실리콘의 재질로 형성된다. Preferably, the waterproof cover 500 is made of a material having elasticity, and is made of a material of rubber, urethane, or silicone.

한편 도 4에 도시된 바와 같이, 리브(540)의 저면에 돌출된 돌기(542)가 형성되고, 플랜지(140)의 상면에는 돌기(542)가 끼움결합되도록 끼움홈(143)이 형성되어 리브(540)의 돌기(542)가 끼움홈(143)에 억지끼움된다. Meanwhile, as shown in FIG. 4, a protrusion 542 protruding from the bottom surface of the rib 540 is formed, and a fitting groove 143 is formed so that the protrusion 542 is fitted on the upper surface of the flange 140. The protrusion 542 of 540 is forcibly fitted into the fitting groove 143.

따라서 방수커버(500)의 리브(540)가 밸브본체(120) 및 플랜지(140)의 상면 일부분을 덮어 밀착됨으로써 기밀성을 갖게 되고, 아울러 돌기(542)가 끼움홈(143)에 억지끼움됨으로써 견고한 고정력과 수밀성을 갖게 되므로 외부로부터 미세한 이물질이나 또는 이송되는 물이 스며들지 않도록 차단하게 되어 내부의 부식을 방지할 수 있게 된다. Therefore, the rib 540 of the waterproof cover 500 covers a portion of the upper surface of the valve body 120 and the flange 140 to have airtightness, and the protrusion 542 is forcibly fitted in the fitting groove 143 to be Since it has fixing power and watertightness, it is possible to prevent internal corrosion by blocking fine foreign substances or transported water from infiltrating from the outside.

비록 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although it has been described in connection with the preferred embodiment, it will be easily recognized by those skilled in the art that various modifications and variations are possible without departing from the gist and scope of the invention, and all such changes and modifications fall within the scope of the appended claims. Is self-explanatory.
