또한 상기 밸브몸체(100)의 내측에 설치되어 관로를 개폐시켜 유체의 흐름을 제어하도록 하는 개폐구(200)는 회동방향에 따라 유체의 흐름을 제어할 수 있도록 한 관통공입구(231)와 관통공출구(232)를 포함하는 관통공(230)이 천공되어 있다.In addition, the opening and closing port 200 which is installed inside the valve body 100 to open and close the pipe to control the flow of fluid has a through hole 231 and a through hole to control the flow of the fluid according to the rotation direction. The through hole 230 including the outlet 232 is drilled.

이와 같은 개폐구(200)의 상측부는 상기 개폐구(200)를 조작하는 손잡이(270)의 회동력을 전달하도록 하는 스핀들(210)이 일체로 형성되어 있다.The upper side of the opening and closing 200 is integrally formed with a spindle 210 to transmit the rotational force of the handle 270 for operating the opening and closing 200.

상기 개폐구(200)는 관통공출구(232)의 상측 주연부에 상부실링홈(240)이 구비되어 있고, 상기 관통공출구(232)의 하측 주연부에는 하부실링홈(250)이 구비되어 있다.The opening and closing hole 200 is provided with an upper sealing groove 240 on the upper peripheral portion of the through hole 232, the lower sealing groove 250 is provided on the lower peripheral portion of the through hole 232.

상기 개폐구(200)의 상부실링홈(240)과 하부실링홈(250)에는 각각 O-링(260)이 끼워져 밸브몸체(100)와의 결합시 기밀성을 갖도록 하였다.The O-ring 260 is fitted into the upper sealing groove 240 and the lower sealing groove 250 of the opening and closing 200 so as to have airtightness when the valve body 100 is coupled with the valve body 100.

이와 같은 본 고안은 조립작업시 스핀들(210)과 일체로 형성된 개폐구(200) 의 상부실링홈(240)과 하부실링홈(250)에 각각 O-링(260)을 끼운 후 밸브몸체(100)의 유입구(110)를 통하여 삽입한 다음 돌출된 스핀들 상측부에 손잡이(270)를 맞추어 고정나사(271)를 조여 줌으로써 모든 조립작업이 완료되게 된다.The present invention, such as the valve body 100 after inserting the O-ring 260 in the upper sealing groove 240 and the lower sealing groove 250 of the opening and closing 200 formed integrally with the spindle 210 during the assembly operation, respectively. Insert through the inlet 110 of the and then tighten the fixing screw 271 by adjusting the handle 270 to the upper side of the protruding spindle to complete all the assembly work.

한편, 상기 밸브몸체(100)의 유출구(120) 내측에는 상기 개폐구(200)를 밀착지지하는 패킹(310)과 상기 패킹(310)을 지지하기 위하여 상기 유출구(120) 내에 나사(323)결합되며 통공(321)이 형성된 패킹받침(320)이 구비된다.On the other hand, inside the outlet 120 of the valve body 100 is coupled to the screw 323 in the outlet 120 to support the packing 310 and the packing 310 to support the opening and closing 200 in close contact. A packing support 320 having a through hole 321 is provided.

상기 패킹(310)은 실리콘재로 이루어짐이 바람직하며, 밸브조작시 상기 개폐구(200)를 견고하게 지지한다.The packing 310 is preferably made of a silicon material, and firmly supports the opening and closing port 200 during the valve operation.

이와 같은 패킹(310)은 상기 개폐구(200)의 회전을 밀착 지지하도록 개폐구(200)의 주연부에 대응 형성된다. 즉, 개폐구(200)의 주연부가 구형인 경우 패킹(310)의 개폐구 접촉부는 이에 대응하여 만곡형성된다.Such a packing 310 is formed corresponding to the periphery of the opening and closing 200 to closely support the rotation of the opening and closing 200. That is, when the periphery of the opening and closing hole 200 is spherical, the opening and closing contact portion of the packing 310 is correspondingly curved.

본 고안에 따른 일 실시예의 상기 개폐구(200)의 외측 주연부는 구형으로 형성됨이 바람직하나 제 2실시예로서 밸브몸체(100)의 내부형상과 일치되는 원통형(도 4 참조)으로 구성될 수도 있다. 이 경우는 개폐구의 가공이 좀더 용이하다.The outer periphery of the opening and closing hole 200 of the embodiment according to the present invention is preferably formed in a spherical shape, but may also be configured as a cylindrical shape (see Fig. 4) to match the internal shape of the valve body 100 as a second embodiment. In this case, processing of the opening and closing port is easier.

도 5는 본 고안의 제 3실시예 요부확대 단면도로서 2개의 관통공출구(232)가 형성되어 있는 것으로 복수개의 유출구(120)를 통하여 유체를 분리하여 배출하도록 하거나, 또는 하나의 유출구(120)에 연결되도록 하되 상기 관통공출구(232)의 크기 를 서로 다르게 형성하여 유체의 공급량이 서로 다르게 조절되도록 하는 등 특수한 경우에 적용할 수 있는 개폐구이다.5 is an enlarged cross-sectional view of a third embodiment of the present invention, in which two through-holes 232 are formed to separate and discharge fluid through a plurality of outlets 120, or one outlet 120. To be connected to the opening and exit port 232 is formed to be different from each other by the opening and closing port that can be applied in a special case, such as to control the supply amount of the fluid differently.

즉 손잡이(270)에 의한 개폐구(200)의 회동각도에 따라서 유체의 공급량이나 공급관로가 조절되도록 하는 것이다.That is, the supply amount of the fluid or the supply line is adjusted according to the rotation angle of the opening / closing opening 200 by the handle 270.

기타 다른 구성 및 작용효과는 제 1실시예와 동일하므로 구체적인 설명은 생략한다.Other configurations and operation effects are the same as those of the first embodiment, and thus detailed description thereof will be omitted.

이상 살펴본 바와 같이 본 고안은 밸브몸체에 삽입 설치되어 유체의 흐름을 제어하도록 하는 개폐구와 상기 개폐구에 손잡이의 회동력을 전달하는 스핀들을 일체화 하여 하나의 부품으로 함으로써 제품의 가공 및 조립작업을 보다 용이하게 하여 제품의 생산성을 향상하고 가공단가를 줄일 수 있도록 한 것으로 산업상 이용가능성이 매우 높은 유용한 기술이다.As described above, the present invention integrates the opening and closing opening for controlling the flow of the fluid to be inserted into the valve body and the spindle for transmitting the rotational force of the handle to the opening and closing, so that the product is easily processed and assembled. In order to improve the productivity of the product and to reduce the processing cost, it is a useful technology with high industrial applicability.
