Description

체크밸브{check valve}Check valve

본 발명은 체크밸브에 관한 것으로, 보다 상세하게는 유체의 일방향 흐름은 가능하도록 하고 역방향으로 흐르는 것은 차단하는 체크밸브에 관한 것이다.
The present invention relates to a check valve, and more particularly to a check valve that allows one-way flow of the fluid and block the flow in the reverse direction.

일반적으로 체크밸브는 유체의 일방향 흐름은 가능하도록 하는 반면, 역방향으로 흐르는 것을 차단하는 밸브의 한 종류로서, 밸브의 직경이나 구조에 따라서 다양한 형태로 이뤄져 있으며, 주로 역류방지를 목적으로 하는 유체배관의 플랜지 또는 정수기의 관로 상에 설치하여 사용되고 있다.In general, the check valve is a type of valve that allows one-way flow of the fluid, but blocks the flow in the reverse direction. The check valve is formed in various forms according to the diameter and structure of the valve. It is installed on the pipeline of the flange or water purifier.

상기와 같은 체크밸브(10)는 도 1에 도시된 바와 같이, 입구가 형성된 하우징(11)의 내부에 스프링(12)이 구비되고, 상기 스프링(12)의 탄력에 의해 밸브시트(14)를 개폐하도록 통공(13')이 형성된 밸브디스크(13)가 구비되며, 상기 하우징(11)의 일측에 결합되어 밸브디스크(13)에 의해 입구가 개폐되는 밸브시트(14)가 구비된다.As shown in FIG. 1, the check valve 10 is provided with a spring 12 inside the housing 11 in which the inlet is formed, and the valve seat 14 is moved by elasticity of the spring 12. A valve disc 13 having a through hole 13 ′ is formed to open and close, and a valve seat 14 coupled to one side of the housing 11 is provided to open and close an inlet by the valve disc 13.

그러나, 종래의 체크밸브는 유체가 유입되어 밸브디스크가 개방된 상태에서 유체가 역방향으로 흘러 역압이 발생하여 입구를 폐쇄할 경우 스프링의 탄성으로 폐쇄하므로 밸브디스크의 흔들림이 발생하여 입구를 정확하게 폐쇄하지 못할 뿐만 아니라 각 부품들 간의 누적공차에 따른 입구의 개방시 압력편차가 발생하므로 유체의 유량이 불규칙하게 배출됨은 물론 누수가 발생할 수도 있는 문제점이 있었다.However, the conventional check valve is closed by the elasticity of the spring when the fluid flows in the reverse direction in the state in which the fluid flows in the reverse direction when the fluid flows in the reverse direction and closes the inlet, so that the valve disc is shaken to close the inlet correctly. In addition, the pressure difference occurs when the inlet is opened due to the cumulative tolerance between the parts, and thus the flow rate of the fluid is irregularly discharged, and there is a problem that leakage may occur.

또한, 체크밸브를 구성하는 부품의 수가 증가하여 제조원가가 상승할 뿐만 아니라 제작공정의 증가로 인한 제품생산성이 저하되는 문제점이 있었다.
In addition, as the number of parts constituting the check valve increases, manufacturing cost increases, and there is a problem in that product productivity decreases due to an increase in the manufacturing process.

이에 본 발명은, 상술한 바와 같은 제반결함을 감안하여 이루어진 것으로, 그 목적은 유체의 유입시에는 유체의 압력에 의해 역류방지부재가 압축되어 하우징의 유입공을 개방하고 역압 발생시에는 역류방지부재가 자체탄성력에 의해 탄력있게 복원되면서 유입공을 폐쇄함으로써 안정적으로 유체의 흐름을 제어할 수 있는 체크밸브를 제공함에 있다.Accordingly, the present invention has been made in view of the above-mentioned defects, and its object is to prevent the backflow preventing member from being compressed by the pressure of the fluid at the time of inflow of the fluid, thereby opening the inlet hole of the housing, and the backflow preventing member when the back pressure is generated. The present invention provides a check valve that can stably control the flow of fluid by closing the inlet hole while being elastically restored by self-elastic force.

또한, 본 발명의 다른 목적은 체크밸브의 내부구조를 간소화하여 제조공정시간 및 제작비용을 절감할 수 있는 체크밸브를 제공함에 있다.
In addition, another object of the present invention to provide a check valve that can reduce the manufacturing process time and manufacturing cost by simplifying the internal structure of the check valve.

The backflow preventing member 122 is compressed to open the inlet hole 111, and when the back pressure is generated, the backflow preventing member 122 is elastically restored by its own elastic force to close the inlet hole 111. ) Is configured, the fixing unit 130 is fixed to prevent the flow of the backflow prevention unit 120 is configured, and comprises a holder 140 is fixed to both sides of the housing 110 is connected to the hose The backflow prevention part 120 includes a body 121 seated on the seating jaw 112 inside the housing 110, and opens and closes the inflow hole 111 elastically to prevent backflow. Prevention member 122 is provided, the body 121 and the backflow prevention member 122 To form the exhaust port 123 'to connect onto and non-return member 122 includes a rib 123 to have its own elastic force, when it more specifically as follows.

상기 역류방지부(120)는 연질로 형성되며, 상기 리브(123)는 몸체(121)와 역류방지부재(122)를 경사지게 연결하는 것이 바람직하다.
The backflow prevention part 120 is formed in a soft shape, the rib 123 is preferably connected to the body 121 and the backflow prevention member 122 inclined.

이하 첨부된 도면에 의거하여 본 발명을 일실시예를 상세하게 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

먼저, 도 3에 도시된 바와 같이, 상기 하우징(110) 내부의 안착턱(112)에 역류방지부(120)의 몸체(121)가 안착되며, 역류방지부재(122)는 하우징(110)의 유입공(111)을 폐쇄하게 된다.First, as shown in FIG. 3, the body 121 of the backflow prevention part 120 is seated on the seating jaw 112 inside the housing 110, and the backflow prevention member 122 is formed of the housing 110. The inlet hole 111 is closed.

상기 몸체(121)와 역류방지부재(122)를 연결하는 리브(123)는 방사상으로 경사지게 형성되어 배출구(123')를 형성함은 물론 역류방지부재(122)에 자체탄성력을 갖게 하여 유입공(111)에 밀착되어 폐쇄하게 된다.The rib 123 connecting the body 121 and the backflow preventing member 122 is formed to be inclined radially to form an outlet 123 'as well as to have its own elastic force in the backflow preventing member 122 to provide an inlet hole ( And close to 111).

상기 역류방지부재(122)는 하우징(110) 내부에 유체가 흐르지 않는 상태에서는 유입공(111)과 밀착상태를 유지하게 되고, 유체가 흐르게 되면 역류방지부재(122)는 유입공(111)과 이격되어 유체가 배출되는 구조로 되어있다.The backflow preventing member 122 maintains a close contact with the inlet hole 111 in a state in which the fluid does not flow in the housing 110, and when the fluid flows, the backflow preventing member 122 is connected to the inlet hole 111. The structure is spaced apart and the fluid is discharged.

상기와 같은 역류방지부(120)의 일측에는 하우징(110)의 내측으로 고정부(130)가 장착되며, 고정부(130)의 단부가 역류방지부(120)의 몸체(121)를 가압함으로써 유체의 흐름시 또는 역압 발생시 역류방지부(120)의 유동을 방지하게 된다.On one side of the reverse flow prevention part 120 as described above, the fixing part 130 is mounted to the inside of the housing 110, and the end of the fixing part 130 presses the body 121 of the backflow preventing part 120. When the fluid flows or when the back pressure is generated to prevent the flow of the backflow prevention unit 120.

또한, 상기 하우징(110)의 양측에는 호스(H)(H')가 연결될 수 있도록 홀더(140)가 각각 고정된다.In addition, holders 140 are fixed to both sides of the housing 110 so that the hoses H and H 'may be connected.

상기와 같이 구성되는 본 발명의 동작상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.

먼저, 도 4에 도시된 바와 같이, 호스(H)를 통해 유체가 일방향으로 흘러 하우징(110) 내부에 관통된 유입공(111)으로 유입된다.First, as shown in FIG. 4, the fluid flows in one direction through the hose H and flows into the inlet hole 111 penetrating into the housing 110.

상기 유입공(111)으로 유입된 유체는 그 압력에 의해 유입공(111)을 폐쇄하고 있던 역류방지부재(122)를 가압하게 된다.The fluid introduced into the inlet hole 111 pressurizes the backflow preventing member 122 closing the inlet hole 111 by the pressure.

이때, 유체의 압력은 유입공(111)을 폐쇄하고 있던 역류방지부재(122)의 탄성력보다 크므로 역류방지부(120)의 몸체(121)와 역류방지부재(122)를 연결하는 리브(123)가 변형되면서 역류방지부재(122)는 유입공(111)에서 이격되어 유입공(111)을 개방하게 되며, 유체는 유입공(111)을 통해 유입되어 역류방지부(120)의 배출구(123')를 통해 타측 호스(H')로 배출된다.At this time, since the pressure of the fluid is greater than the elastic force of the backflow preventing member 122 closing the inlet hole 111, the rib 123 connecting the body 121 and the backflow preventing member 122 of the backflow preventing part 120. ) Is deformed and the backflow preventing member 122 is spaced apart from the inlet hole 111 to open the inlet hole 111, and the fluid is introduced through the inlet hole 111 to discharge the outlet 123 of the backflow prevention part 120. It is discharged to the other hose (H ') through').

또한, 도 5에 도시된 바와 같이, 역압이 발생하게 되면, 상기 유입공(111)에서 이격되어 개방상태를 유지하고 있던 역류방지부재(122)는 자체탄성력에 의해 최초상태로 복원되면서 하우징(110)의 유입공(111)에 밀착되어 폐쇄하게 되며, 호스(H)를 통해 흐르던 유체는 더 이상 유입공(111)을 통해 유입되지 않게 되는 것이다.In addition, as shown in FIG. 5, when the back pressure is generated, the backflow preventing member 122 spaced apart from the inlet hole 111 and maintained in the open state is restored to its initial state by its own elastic force and thus the housing 110. In close contact with the inlet hole 111, the fluid flowing through the hose (H) is no longer introduced through the inlet hole (111).

상기 역류방지부재(122)는 리브(123)에 의한 자체탄성력으로 유입공(111)을 폐쇄하므로 흔들리지 않고 항상 동일한 위치에 밀착될 수 있는 것이다.The backflow prevention member 122 is to close the inlet hole 111 by its own elastic force by the rib 123, so that it can always be in close contact with the same position without shaking.

상기에서 서술한 본 발명 체크밸브(100)는, 정수기의 관로 상에 설치되어 사용될 수도 있으며, 유체가 한 방향으로 흐르는 구조의 다른 산업분야에도 적용이 가능한 것이다.The check valve 100 of the present invention described above may be installed and used on a pipe of a water purifier, and may be applied to other industrial fields in which a fluid flows in one direction.
