이중기밀부재가 구비된 체크-인 볼 밸브{check-in ball valve with dual sealing seat}Check-in ball valve with dual sealing seat

본 발명은 체크밸브가 내장된 볼밸브에 관한 것으로서, 더욱 상세하게는 체크밸브가 접하는 볼밸브의 내측에 기밀부재를 구비하되, 기밀부재를 이중으로 구성하여 기밀부재의 마모 및 손상을 줄이고 체크밸브와 볼밸브와의 기밀성이 크게 향상될 수 있도록 한 이중기밀부재가 구비된 체크-인 볼밸브에 관한 것이다.The present invention relates to a ball valve with a built-in check valve, and more particularly provided with an airtight member on the inside of the ball valve in contact with the check valve, by configuring the airtight member in double to reduce the wear and damage of the airtight member check valve The present invention relates to a check-in ball valve provided with a double hermetic member to greatly improve airtightness with the ball valve.

일반적으로 밸브는 관로(管路)의 도중이나 용기에 설치하여, 유체의 유량 또는 압력 등의 제어를 하는 장치로서, 볼 밸브, 스톱밸브, 게이트 밸브, 체크 밸브등 여러 가지 구조와 형태로 널리 사용되고 있다.In general, the valve is installed in the pipeline or in a container to control the flow rate or pressure of the fluid, and is widely used in various structures and forms such as ball valves, stop valves, gate valves, and check valves. have.

이 중 볼 밸브는 그 구조가 간단하고 값이 저렴하여 수도관이나 도시가스관, 냉동장치의 냉매관과 같이 대체로 일정한 유압이나 기압을 요하는 곳에서 공급유체의 압력이나 유량을 조절하는데 쓰이고 있는 것으로, 볼 밸브 장치의 본체 내부에는 중심을 관통하는 관통공이 형성된 유로를 개폐하는 볼 타입 디스크가 내장되어 있고, 상기 볼 타입 디스크를 유로 내에서 회전시키는 조절손잡이가 마련되어 있는 바, 조절손잡이의 회전에 따라 유로를 개방하거나 폐쇄하도록 하고 있다.Among these, the ball valve is used to control the pressure or flow rate of the supply fluid in a place requiring a constant hydraulic pressure or air pressure, such as a water pipe, a city gas pipe, or a refrigerant pipe of a refrigerating device because of its simple structure and low cost. A ball type disk for opening and closing a flow path having a through hole penetrating the center is built in the main body of the valve device, and an adjustment knob for rotating the ball type disk in the flow path is provided. Open or closed.

또한, 상기 볼 밸브의 경우, 유체가 역류되는 것을 방지하기 곤란한 문제점이 있어 설치되는 관로에 필요에 따라 유체의 흐름이 역류되는 것을 방지하는 체크밸브가 별도로 더 설치되어 있다. In addition, in the case of the ball valve, there is a problem that it is difficult to prevent the back flow of the fluid, the check valve for preventing the flow of the back flow of the fluid as needed is further provided separately.

그러나, 하나의 관로에 볼 밸브와 체크밸브를 각각 설치함에 따라 설치비용이 가중되는 문제점이 있고, 관리 및 보수작업시에 과다한 비용과 인원이 필요하게 된다.However, there is a problem in that the installation cost is increased by installing each of the ball valve and the check valve in a single pipeline, and excessive costs and personnel are required for management and maintenance work.

이러한 문제점을 해결하기 위해 체크밸브가 내장된 볼 밸브가 제안된 바 있다.In order to solve this problem, a ball valve with a check valve has been proposed.

도 1은 종래 체크밸브가 내장된 볼 밸브의 구성을 나타낸 구성도로서, 도시된 바와 같이, 몸체(1)의 상부측에 구비된 손잡이(2)와, 상기 몸체(1)의 내부에 내장되고 중심부가 관통되어 유로(3a)가 형성된 볼 밸브체(3)와, 상기 볼 밸브체(3)의 내부에 내장되어 상기 볼 밸브체(3)의 개방된 유로(3a)의 일측을 차단하는 체크밸브체(4)로 구성되어 있다.1 is a block diagram showing a configuration of a ball valve in which a conventional check valve is incorporated, and as shown in FIG. 1, a handle 2 provided at an upper side of a body 1 and a built-in inside of the body 1 are provided. A check for blocking the one side of the ball valve body 3 in which the center part penetrates through which the flow path 3a was formed, and the inside of the ball valve body 3, and the open flow path 3a of the ball valve body 3 is blocked. It consists of the valve body 4.

상기 체크밸브체(4)는, 상기 몸체(1)의 내부에 구비된 가이드부(5)의 내측에 인입된 슬라이딩부(4a)와, 상기 개방된 유로(3a)를 차단하는 유로개폐부(4b)로 구성되어 있으며, 체브밸브체(4)의 유로개폐부(4b) 후방측에는 상기 가이드부(5)의 외면에 끼워진 스프링(6)이 구비되어 있다.The check valve body 4 includes a sliding part 4a drawn inside the guide part 5 provided in the body 1 and a flow path opening and closing part 4b for blocking the open flow path 3a. And a spring 6 fitted to the outer surface of the guide portion 5 on the rear side of the flow path opening and closing portion 4b of the valve valve body 4.

따라서, 손잡이(2)를 돌림에 따라 볼 밸브체(3)의 유로(3a)가 개방되면, 상기 몸체(1)의 인입부(1a)측으로 유체가 볼 밸브체(3)의 유로(3a) 내부로 인입되고 이에 따라 인입되는 유체의 압력에 의해 상기 체크밸브체(4)가 열리게 되어 상기 몸체(1)의 인입부(1a)측으로 인입되는 유체는 상기 개방된 볼 밸브체(3)의 유로(3a)를 지나 몸체(1)의 배출부(1a)측으로 배출된다.Therefore, when the flow path 3a of the ball valve body 3 is opened as the handle 2 is rotated, fluid flows toward the inlet 1a side of the body 1 and the flow path 3a of the ball valve body 3 is rotated. The check valve body 4 is opened due to the pressure of the fluid introduced into it, and thus the fluid introduced into the inlet 1a side of the body 1 is flowed through the open ball valve body 3. Passed through (3a) is discharged to the discharge portion (1a) side of the body (1).

또한, 상기 볼 밸브체(3)의 내부에 구비된 체크밸브체(4)에 의해 상기 몸체(1)의 내부를 따라 흐르는 유체의 역류됨을 방지하고 있다.In addition, the check valve body 4 provided inside the ball valve body 3 prevents backflow of the fluid flowing along the inside of the body 1.

이러한, 종래 체크밸브가 구비된 볼 밸브는, 내부에 체크밸브가 더 구비되어 있음으로써, 흐르는 유체의 역류되는 것을 방지하고 볼 밸브의 내부에 체크밸브가 구비되어 있음에 따라 하나의 관로에 볼 밸브와 체크밸브를 각각 설치함에 따라 야기되는 문제점이 해결된다.Such a conventional ball valve is provided with a check valve, the check valve is further provided therein, to prevent the back flow of the flowing fluid and as the check valve is provided in the ball valve in accordance with the ball valve in one conduit The problems caused by installing the and check valves, respectively, are solved.

그러나, 종래 체크밸브가 구비된 볼 밸브의 경우, 상기 볼 밸브체(3)와 이 볼 밸브체(3)의 내부에 구성된 체크밸브체(4)와의 기밀성을 위해 상기 체크밸브체(4)의 유로개폐부(4b) 양측에 밀폐링(4c)를 더 구성하고 있는 바, 장기간 사용할 경우 고무재질로 형성된 밀폐링(4c)이 볼밸브체(3)의 내측 환형시트부(3b)에 의해 선접촉에 의해 반복적으로 접촉함에 따라, 금속재질의 볼밸브체(3)와 고무재질의 밀폐링(4c)과의 접촉에 의해 상기 밀폐링(4c)에 반복적인 충격이 가해짐으로써, 밀폐링(4c)의 마모가 발생되어 볼 밸브체(3)와 체크밸브체(4)와의 기밀성이 저하되는 문제점이 있다. However, in the case of a ball valve equipped with a conventional check valve, the check valve body 4 is used for airtightness between the ball valve body 3 and the check valve body 4 formed inside the ball valve body 3. The sealing ring 4c is further formed on both sides of the flow path opening and closing portion 4b, so that when used for a long time, the sealing ring 4c formed of rubber material is in line contact with the inner annular seat portion 3b of the ball valve body 3. By repeatedly contacting the ball valve body 3 of the metal material with the sealing ring 4c of the rubber material, the sealing ring 4c is repeatedly applied to the sealing ring 4c. ), There is a problem that the airtightness between the ball valve body 3 and the check valve body 4 is lowered.

이에 따라, 자주 밸브를 교체하여야 하는 번거로움은 물론 가중되는 비용에 의해 경제적인 비용부담을 느끼게 된다.As a result, the burden of having to replace the valve frequently, as well as the increased cost, feels an economic cost burden.

뿐만 아니라, 기밀성을 유지하기 위한 밀폐링(4c)이 체크밸브체(4)의 유로개폐부(4b) 둘레면에 끼움결합되어 있음으로써, 체크밸브체(4)의 유로개폐부(4b)와 상기 밀폐링(4c)과의 결속력이 저하되어 밀폐링(4c)의 견고한 밀착력이 유지되지 못함에 따라 볼밸브체(3)와 체크밸브체(4)와의 기밀성이 저하되는 문제점이 있다.In addition, the sealing ring 4c for maintaining the airtightness is fitted to the circumferential surface of the flow path opening and closing portion 4b of the check valve body 4, so that the flow path opening and closing portion 4b of the check valve body 4 and the airtight seal are closed. There is a problem that the tightness between the ball valve body 3 and the check valve body 4 is lowered because the binding force with the ring 4c is lowered and the tight adhesion of the sealing ring 4c is not maintained.

본 발명은 종래 체크밸브가 구비된 볼 밸브가 지닌 문제점을 해결하기 위해 안출된 것으로서, 체크밸브체의 유로개폐부가 접하는 볼밸브체의 내측에 주기밀부재와 보조기밀부재를 구비하여 볼밸브체와 체크밸브체와의 기밀성이 이중으로 유지되도록 함으로써 기밀성을 향상시킬 수 있을 뿐만 아니라, 주기밀부재를 금속재질로 형성하고 보조기밀부재를 합성수지재질로 형성하되 상기 보조기밀부재가 호형면을 갖는 유로개폐부에 면접촉되어 기밀성이 유지되도록 하여 기밀성이 크게 향상될 수 있으며 보조기밀부재의 마모성을 미연에 방지할 수 있도록 한 이중기밀부재가 구비된 체크-인 볼 밸브를 제공함에 그 목적이 있다.The present invention has been made to solve the problems of the conventional ball valve provided with a check valve, the ball valve body and the main airtight member and the auxiliary airtight member provided on the inner side of the ball valve body in contact with the passage opening and closing portion of the check valve body and By maintaining the airtightness with the check valve body in double, not only the airtightness can be improved, but also the main airtight member is formed of a metal material and the auxiliary airtight member is formed of a synthetic resin material, but the auxiliary airtight member has an arc surface. It is an object of the present invention to provide a check-in ball valve equipped with a double hermetic member that can be in contact with the surface to maintain the airtightness can greatly improve the airtightness and prevent the wear of the auxiliary hermetic member in advance.
