본 발명은 유체 제어밸브용 실링부재에 관한 것으로, 더욱 구체적으로는 밸브의 폐쇄시에 발생하는 유체압을 이용하여 밀폐력을 갖도록 함과 아울러 내열성 및 내마모성이 우수한 유체 제어밸브용 실링부재에 관한 것이다.The present invention relates to a sealing member for a fluid control valve, and more particularly, to a sealing member for a fluid control valve having a sealing force using fluid pressure generated when the valve is closed and having excellent heat resistance and wear resistance.

The first and second flow passages 11 and 12 and the valve seat 30 formed at the portion where the first and second flow passages 11 and 12 are in communication are spaced apart from or in contact with the valve seat 30, and the fluid A valve body 40 for controlling the valve body 40, the rear end of the valve body 40 is elastically supported by a spring 42, and a support 44 formed at the rear end of the valve body 40 to guide sliding; It consists of a support guide 48 on which a support end 46 is formed so that the rear end of the valve body 40 is supported , and a sealing member 50 fitted to the valve seat 30. The sealing member (50) is a configuration of a pressure groove portion 52 formed on the front portion and generating a pressing force by the inflowing fluid, and a pressure wing 54 in which both sides of the pressure groove portion 52 are pressed outward by the pressure force of the fluid. As a result, close sealing is achieved by the pressure blades 54 in contact with the front end of the valve body 40 when the flow path of the valve is blocked.
상기 실링부재(50)는 테프론(Teflon) 재질로 만들어지며, 테프론은 고무, 실리콘 등과 같은 일반탄성체와 달리 탄성력을 약하지만 내열성, 내마모성이 우수하여 내구성을 크게 높일 수 있도록 한다.The sealing member 50 is made of Teflon (Teflon) material, Teflon is weak in elasticity unlike general elastic materials such as rubber, silicone, etc., but it has excellent heat resistance and wear resistance so that durability can be greatly improved.
이러한 볼 발명은 밸브몸체(10)의 밸브실에서 밸브체(40)가 전진 이동하여 유로를 차단하는 수단으로 역류를 방지하게 될 때는 밸브체(40)의 외측면 전단부가 밸브시트(30)에 밀착되어지되 밸브시트(30)에 끼움 결합되는 실링부재(50)에 의해 밀폐되어 역류방지를 하게 된다.This ball invention is a means for blocking the passage by moving the valve body 40 forward in the valve chamber of the valve body 10 to prevent reverse flow, the front end of the outer surface of the valve body 40 is attached to the valve seat 30. It is tightly closed by the sealing member 50 fitted to the valve seat 30 to prevent reverse flow.
그리고 밸브몸체(10)의 유로에 유체가 유통될 수 있도록 밸브체(40)는 후진시에는 받침안내대(48)의 받침단부(46)에 의해 받쳐지는 형태로 후진범위를 제한한 상태에서 유로 개방이 이루어진다.In addition, the valve body 40 is supported by the support end 46 of the support guide 48 so that the fluid can flow through the flow path of the valve body 10, and the flow path is limited in the backward range. opening takes place

When the flow of the valve is blocked by the configuration of the pressure groove portion 52 formed in and generating a pressing force by the inflow fluid and the pressure wing 54 so that both sides of the pressure groove portion 52 are pressed outward by the pressure force of the fluid In this way, tight sealing is achieved by the pressure blades 54 in contact with the front end side of the valve body 40.
상기의 실링부재(50)는 테프론(Teflon) 재질로 만들어지고, 실링부재(50)의 가압날개(54)는 밸브체(40)의 전단 측부에 접촉되어 밀폐 기능을 수행하게 된다.The sealing member 50 is made of a Teflon material, and the pressure wing 54 of the sealing member 50 is in contact with the front end side of the valve body 40 to perform a sealing function.
상기와 같은 본 발명은 제2공간부(25)의 유체배출부(26)와 배압조절부(27)는 압력조절판(28)으로 분할 구획되어 있으므로 유체배출부(26)에 위치한 제2공간부(25)에서 유체배출부(26)을 통하여 유체가 배출되면 배압조절부(27)에 위치한 제2공간부(25)는 압력이 상대적으로 증가하여 압력조절판(28)과 지지대(44)로 연결된 밸브체(40)를 밸브시트(30)와 이격시켜 유체가 제1,2공간부(21)(25)가 연통되게 되면서 제2공간부(25)에 유체가 유입된다.In the present invention as described above, since the fluid discharge part 26 and the back pressure control part 27 of the second space part 25 are divided by the pressure control plate 28, the second space part located in the fluid discharge part 26 When the fluid is discharged through the fluid discharge part 26 in (25), the pressure in the second space part 25 located in the back pressure control part 27 relatively increases and is connected to the pressure control plate 28 and the support 44. By separating the valve body 40 from the valve seat 30, the fluid flows into the second space 25 while the first and second spaces 21 and 25 are communicated with each other.
이러한 제2공간부(25)에 유입되는 유체에 의해 제1,2공간부(21)(25)의 압력균형이 이루어지면 밸브체(40)가 밸브시트(30)와 접촉하는 밸브의 유로 차단시에 밸브시트(30)에 끼움 결합되는 실링부재(50)는 밸브체(40)의 전단 측단부에 접촉됨과 아울러 밸브시트(30)에 결합되는 실링부재(50)의 가압홈부(52)에 유체가 유입되면서 가압력을 발생시키게 되며, 이렇게 가압홈부(52)에 가해지는 가압력은 가압홈부(52)의 양측 가압날개(54)에 전달되어 외측으로 가압이 이루어지는 수단으로 밸브체(40)에 접촉이 되는 가압날개(54)에 의해 긴밀한 밀폐가 이루어지는 것이다.When the pressures of the first and second spaces 21 and 25 are balanced by the fluid flowing into the second space 25, the valve body 40 blocks the passage of the valve contacting the valve seat 30. The sealing member 50 fitted to the valve seat 30 when in contact with the front end side of the valve body 40 and also to the pressing groove 52 of the sealing member 50 coupled to the valve seat 30. As the fluid flows in, pressurized force is generated, and the pressurized force applied to the pressurized groove 52 is transmitted to the pressurized wings 54 on both sides of the pressurized groove 52, and is pressurized outward. Contact the valve body 40 Close sealing is achieved by the pressure blades 54 that become.
이와 같은 본 발명은 탄성력이 약한 테프론으로 만들어진 실링부재(50)의 밀폐력을 높이기 위해 밸브의 폐쇄시에 발생되는 유체압을 이용하여 실링부재(50)의 밀폐기능을 최대한 발휘할 수 있도록 되어 있고, 테프론의 내열성 및 내마모성을 가진 실링부재(50)의 구성으로 내구성을 크게 높여 밸브의 작동 신뢰성을 향상시킬 수 있는 것이다.In the present invention, in order to increase the sealing force of the sealing member 50 made of Teflon, which has weak elasticity, the sealing function of the sealing member 50 can be maximized by using the fluid pressure generated when the valve is closed, and the Teflon With the configuration of the sealing member 50 having heat resistance and wear resistance of, the operation reliability of the valve can be improved by greatly increasing durability.
