Description

조절밸브용 파이프 조립장치{Pipe assembly for control valve}[0001] The present invention relates to a pipe assembly for a control valve,

본 발명은 조절밸브용 파이프 조립장치에 대한 것으로서, 더욱 상세하게는 스프링의 기울어짐을 방지할 수 있을 뿐만 아니라 그 구성을 간단하게 구현할 수 있는 조절밸브용 파이프 조립장치에 대한 것이다.The present invention relates to a pipe assembly apparatus for a control valve, and more particularly, to a pipe assembly apparatus for a control valve that can prevent the tilting of the spring as well as simplify the configuration thereof.

조절밸브는 내연기관의 냉각수의 회로를 조절하는 역할을 한다. 독일 공개특허 DE102009014047호에는 종래의 조절밸브가 개시되어 있으며, 도 1은 상기의 독일 공개특허에서 개시된 조절밸브의 일 실시예이다.The regulating valve serves to regulate the circuit of the cooling water of the internal combustion engine. German Patent DE102009014047 discloses a conventional regulating valve, and Fig. 1 is an embodiment of the regulating valve disclosed in the German patent.

도 1에 도시된 종래의 조절밸브는 패드(3)와, 밀봉링(8)과, 받침대(12)와, 와셔스프링(5)을 구비한다.The conventional control valve shown in Fig. 1 has a pad 3, a seal ring 8, a pedestal 12, and a washer spring 5.

패드(3)의 일단은 밸브(3)에 접촉되고 와셔스프링(5)이 받침대(12)를 가압하여 패드(4)가 밸브(3)에 밀착되도록 한다. 그래서 패드(4)와 밸브(3) 사이를 밀폐시킨다. 또한, 밀봉링(8)이 받침대(12)와 패드(4) 사이에 게재되어 유체가 외부로 유출되는 것을 방지시킨다.One end of the pad 3 is brought into contact with the valve 3 and the washer spring 5 presses the pedestal 12 so that the pad 4 is brought into close contact with the valve 3. So that the space between the pad 4 and the valve 3 is sealed. Further, the seal ring 8 is placed between the pedestal 12 and the pad 4 to prevent the fluid from flowing out.

도 1에 도시된 종래의 조절밸브의 경우 스프링이 기울어지지 않도록 하는 가이드가 구비되어 있지 아니하다. 그래서 스프링에 압력이 많이 가해지면 스프링이 기울어져서 이탈 및 편심된다는 문제점이 있었다.In the case of the conventional control valve shown in FIG. 1, there is no guide for preventing the spring from tilting. Therefore, when a large amount of pressure is applied to the spring, there is a problem that the spring tilts and is disengaged and eccentric.

이 문제점을 해결하기 위해서 압력을 받더라도 기울어지지 않는 와셔스프링을 사용할 수 있지만 이 경우 와셔스프링이 고가이므로 비용이 많이 소요된다는 문제점이 있다.To solve this problem, it is possible to use a washer spring which is not tilted even under pressure, but in this case, the washer spring is expensive and the cost is high.

또한 밀봉링(8)을 반경방향으로 팽창시켜 밀봉시키기 위해서 별도의 받침대(12)가 필요하므로 그 구성이 복잡하다는 문제점이 있었다.Further, a separate pedestal 12 is required to expand and seal the seal ring 8 in the radial direction, so that the structure is complicated.

본 발명은 상기의 문제점을 해결하기 위한 것이다. 본 발명은 스프링이 기울어지는 것을 방지할 수 있는 조절밸브용 파이프 조립장치를 제공하는 것을 목적으로 한다.The present invention is intended to solve the above problems. SUMMARY OF THE INVENTION It is an object of the present invention to provide a pipe assembling apparatus for a control valve which can prevent the spring from tilting.

또한, 본 발명은 별도의 받침대가 필요하지 아니하여 그 구성을 간단하게 할 수 있는 조절밸브용 파이프 조립장치를 제공하는 것을 목적으로 한다.Another object of the present invention is to provide a pipe assembly apparatus for a control valve which can simplify the construction without requiring a separate pedestal.

본 발명에 따른 조절밸브용 파이프 조립장치는 공급연결구와, 패드와, 씰과, 탄성부재를 포함한다. 상기 공급연결구는 일단이 밸브하우징에 삽입되어 밸브에 유체가 유입될 수 있는 유로를 형성한다. 상기 패드는 일단이 상기 공급연결구의 일단을 감싸고 삽입돌기가 형성되며, 타단이 밸브에 접촉한다. 상기 씰은 철심에 고무가 감싸서 형성되며,상기 공급연결구와 상기 밸브하우징 사이를 밀봉시킬 수 있도록 상기 공급연결구와 상기 밸브하우징 사이에 위치하여 상기 패드의 삽입돌기가 되어 상기 패드와 결합된다. 상기 탄성부재는 상기 밸브하우징과 상기 공급연결구 사이에 위치하며, 일단은 상기 공급연결구에 지지되고 상기 패드와 상기 밸브 사이를 밀폐시키도록 타단이 상기 씰을 가압한다.A pipe assembly apparatus for a control valve according to the present invention includes a supply connection, a pad, a seal, and an elastic member. The supply end is inserted into the valve housing at one end to form a flow path through which fluid can flow into the valve. One end of the pad surrounds one end of the supply connection port, an insertion protrusion is formed, and the other end contacts the valve. The seal is formed by wrapping rubber on an iron core and is positioned between the supply connection port and the valve housing so as to seal between the supply connection port and the valve housing and becomes an insertion protrusion of the pad to be coupled with the pad. The elastic member is disposed between the valve housing and the supply connection port. One end of the elastic member is supported by the supply connection port, and the other end presses the seal so as to close the gap between the pad and the valve.

또한, 상기의 파이프 조립장치는 상기 공급연결구와 상기 밸브하우징의 사이를 밀폐시키기 위한 오링을 더 포함하는 것이 바람직하다.The pipe assembling apparatus may further include an O-ring for sealing the gap between the supply connection port and the valve housing.

또한, 상기의 파이프 조립장치에 있어서, 상기 패드는 PTFE(폴리 테트라 플우오로 에틸렌)로 형성되며,In the pipe assembly apparatus, the pad may be formed of PTFE (polytetrafluoroethylene)

상기 탄성부재는 코일스프링인 것이 바람직하다.The elastic member is preferably a coil spring.

본 발명에 의하면 밸브하우징과 공급연결구 사이에서 스프링이 안내되므로 스프링에 힘이 가해지더라도 스프링이 기울어져서 이탈 및 편심되는 것을 방지할 수 있다. 따라서 탄성부재로 와셔스프링 뿐만 아니라 일반 스프링의 사용이 가능하여 비용을 줄일 수 있다.According to the present invention, since the spring is guided between the valve housing and the supply connection, it is possible to prevent the spring from being tilted and released and eccentric even if the spring is applied with a force. Therefore, it is possible to use not only the washer spring but also the ordinary spring as the elastic member, thereby reducing the cost.

도 2 내지 도 5를 참조하여 본 발명에 따른 조절밸브용 파이프 조립장치의 일 실시예를 설명한다.An embodiment of a pipe assembly apparatus for a control valve according to the present invention will be described with reference to Figs. 2 to 5. Fig.

본 발명에 따른 조절밸브용 파이프 조립장치의 일 실시예는 공급연결구(50)와, 패드(60), 씰(63)과, 탄성부재(65)와, 오링(70)을 포함한다.An embodiment of the pipe assembly apparatus for a control valve according to the present invention includes a supply connection port 50, a pad 60, a seal 63, an elastic member 65, and an O-ring 70.

공급연결구(50)는 일단(51)이 밸브하우징(83)에 삽입되어 밸브(81)로 유체가 유입될 수 있는 유로를 형성한다. 즉 공급연결구(50)의 일단(51)은 밸브하우징(83)에 둘러싸여 있다.The supply connection port 50 has one end 51 inserted into the valve housing 83 to form a flow path through which the fluid can flow into the valve 81. That is, one end 51 of the supply connection port 50 is surrounded by the valve housing 83.

패드(60)는 일단이 공급연결구(50)의 일단을 감싸고 타단이 밸브(81)에 접촉한다. 그리고 패드(60)의 일단에는 삽입돌기(61)가 형성되어 있다. 패드(60)는 밸브(81)에 밀착하여 패드(60)와 밸브(81) 사이를 밀폐시키기 위하여 PTFE(폴리 테트라 플우오로 에틸렌)로 형성되는 것이 바람직하다.One end of the pad 60 surrounds one end of the supply connection port 50, and the other end thereof contacts the valve 81. An insertion protrusion 61 is formed at one end of the pad 60. The pad 60 is preferably formed of PTFE (polytetrafluoroethylene) in close contact with the valve 81 to seal the gap between the pad 60 and the valve 81.

씰(63)은 공급연결구(50)와 밸브하우징(83) 사이를 밀봉시키기 위하여 패드(60)의 일단에 결합된다. 즉 패드(60)의 삽입돌기(61)가 씰(63)에 삽입되어 패드(60)와 씰(63)이 결합된다. 그리고 씰(60)은 공급연결구(50)와 밸브하우징(83)의 밀봉을 위하여 내부에 철심에 삽입되고, 철심을 고무가 감싸서 형성되는 것이 바람직하다. 씰(63)은 내부에 철심이 형성되어 있으므로 조립시 패드(60)의 삽입돌기(61)를 삽입시켜 패드(60)에 결합이 될 수 있으며, 외부는 고무로 형성되어 있으므로 하중이 가해지면 변형이 가능하여 공급연결구(50)와 밸브하우징(83) 사이를 밀폐시킬 수 있다.The seal 63 is coupled to one end of the pad 60 to seal between the feed connection 50 and the valve housing 83. The insertion protrusion 61 of the pad 60 is inserted into the seal 63 and the pad 60 and the seal 63 are engaged. The seal 60 is preferably inserted into the iron core to seal the supply connection port 50 and the valve housing 83, and the iron core is formed to be wrapped with rubber. Since the seal 63 is formed with an iron core therein, it can be engaged with the pad 60 by inserting the insertion protrusion 61 of the pad 60 when assembled. When the load is applied, the seal 63 is deformed So that the gap between the supply connection port 50 and the valve housing 83 can be sealed.

탄성부재(65)는 밸브하우징(83)과 공급연결구(50) 사이에 위치하며, 일단은 공급연결구(50)에 지지되고 타단은 패드(60)와 밸브(81) 사이를 밀폐시키도록 씰(63)을 가압한다. 탄성부재(65)가 씰(63)을 가압하면 패드(60)가 밸브(81)에 밀착되어 패드(60)와 밸브(81) 사이가 밀폐된다. 탄성부재(65)로는 스프링이 사용되며, 이때 탄성부재(65)는 공급연결구(50)와 밸브하우징(83) 사이에 위치하므로 공급연결구(50) 및 밸브하우징(83)이 벽 역할을 하여 탄성부재(65)가 기울어지는 것을 방지한다. 종래의 경우 스프링이 기울어지는 경우가 발생하거나 이를 방지하기 위하여 기울어지지 않는 와셔스프링을 사용하였지만, 본 실시예의 경우 공급연결구(50) 및 밸브하우징(83)에 의하여 이것이 방지하므로 일반 스프링을 사용하더라도 기울어지지 않는다.The elastic member 65 is positioned between the valve housing 83 and the supply port 50 and is supported at the supply port 50 at one end and sealed at the other end to seal the pad 60 and the valve 81 63). When the elastic member 65 presses the seal 63, the pad 60 is brought into close contact with the valve 81 to seal the gap between the pad 60 and the valve 81. Since the elastic member 65 is located between the supply connection port 50 and the valve housing 83 at this time, the supply connection port 50 and the valve housing 83 serve as a wall, Thereby preventing the member 65 from tilting. In the present embodiment, the washer spring is used to prevent the spring from tilting in order to prevent or prevent the spring from tilting. However, in the present embodiment, since the supply connection port 50 and the valve housing 83 prevent this, It does not.

오링(70)은 공급연결구(50)와 밸브하우징(83)의 사이에 위치하여 이 사이로 유체가 유출되는 것을 방지되도록 밀폐시킨다.The O-ring 70 is positioned between the supply connection port 50 and the valve housing 83 and seals the fluid to prevent the fluid from flowing out therebetween.
