Description

멀티웨이밸브 장치 {MULTIWAY VALVE APPARATUS}Multi-way valve device {MULTIWAY VALVE APPARATUS}

본 발명은 밸브의 실링 구조를 단순화하는 멀티웨이밸브 장치에 관한 것이다.The present invention relates to a multi-way valve device that simplifies the sealing structure of the valve.

차량의 시동 초기 냉간 조건에서 엔진은 충분히 웜업된 조건 대비 연비가 좋지 않다. 그 이유는, 냉간시 오일 온도가 낮은 상태에서 오일의 높은 점도로 인해 엔진의 마찰이 크고, 또한 실린더 벽면의 온도가 낮아 벽면으로의 열손실이 크며, 연소 안정성이 떨어지기 때문이다.In the cold condition at the initial start of the vehicle, the fuel efficiency is not good compared to the condition in which the engine is sufficiently warmed up. The reason is that the engine friction is large due to the high viscosity of the oil when the oil temperature is low when cold, and the heat loss to the wall surface is large due to the low temperature of the cylinder wall surface, and combustion stability is poor.

따라서, 차량의 연비 향상 및 엔진 내구성 향상을 위해서는 시동 초기에 엔진의 온도를 정상 온도로 빠르게 승온시켜주는 것이 필요하다.Accordingly, in order to improve fuel efficiency and engine durability of the vehicle, it is necessary to rapidly increase the temperature of the engine to a normal temperature at the initial stage of starting.

이를 위한 엔진의 열관리 제어는 냉간 시동 시 엔진에서 발생하는 열을 최대한 엔진을 웜업하는데 이용함으로써, 연비, 출력 향상 및 배출가스 저감 효과를 얻는 기술을 말하는 것으로, 대표적인 기술로는 유동정지밸브, 클러치 타입 워터펌프, 전동식 워터펌프, 멀티웨이밸브 등이 있다.For this purpose, engine thermal management control refers to a technology that obtains the effect of improving fuel efficiency, output and reducing emissions by using the heat generated from the engine during cold start to warm up the engine as much as possible. Representative technologies include flow stop valve and clutch type. There are water pumps, electric water pumps, and multi-way valves.

여기서, 멀티웨이밸브의 경우, 밸브의 회전 위치에 따라 유체의 유통방향이 결정된다. 이러한 밸브는 유통로에 대한 씰링 구조가 필수적으로 요구되는데, 종래의 씰링 구조는 포트의 주변으로 사이드 씰, 밸브에 접촉되는 테프론 씰, 이들을 탄성 지지하는 웨이브 스프링이 요구된다. 이에 따라, 종래의 씰링 구조는 전체 크기가 커지게 되고, 부품수도 증대되어 제조 단가도 상승되는 문제가 있다.Here, in the case of a multi-way valve, the flow direction of the fluid is determined according to the rotational position of the valve. For such a valve, a sealing structure for the flow path is essential, and the conventional sealing structure requires a side seal around the port, a Teflon seal in contact with the valve, and a wave spring elastically supporting them. Accordingly, the conventional sealing structure has a problem in that the overall size is increased, the number of parts is increased, and the manufacturing cost is also increased.

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.The matters described as the background art above are only for improving the understanding of the background of the present invention, and should not be taken as acknowledging that they correspond to the prior art already known to those of ordinary skill in the art.

특히, 씰부재(300)에는 탄성 변형 가능하게 이루어진 탄성부재(400)가 마련됨으로써, 씰부재(300)가 탄성부재(400)를 통해 밸브(500)측으로 탄성 지지됨에 따라 밸브(500)에 밀착된다. 즉, 탄성부재(400)는 씰부재(300)에 마련된 상태에서 통로부(210)에 접촉되며, 통로부(210)에 대해 씰부재(300)가 밸브(500)측으로 이동되도록 탄성력을 인가함에 따라, 씰부재(300)와 밸브(500)의 밀착성이 향상되도록 한다.In particular, the sealing member 300 is provided with an elastic member 400 that is elastically deformable, so that the sealing member 300 is elastically supported toward the valve 500 through the elastic member 400 to closely adhere to the valve 500 . do. That is, the elastic member 400 is in contact with the passage portion 210 in a state provided in the seal member 300, and applying an elastic force to the passage portion 210 so that the seal member 300 moves toward the valve 500. Accordingly, the adhesion between the seal member 300 and the valve 500 is improved.

이와 같이, 본 발명은 씰부재(300)가 연결포트(200)의 통로부(210)에 끼워짐에 따라, 연결포트(200)와 밸브(500) 사이의 씰링이 수행되며, 별도의 씰과 이를 탄성지지하기 위한 스프링 구조가 삭제됨에 따라 구조가 단순화되어 레이아웃이 축소된다.As such, in the present invention, as the sealing member 300 is fitted into the passage portion 210 of the connection port 200, sealing between the connection port 200 and the valve 500 is performed, and a separate seal and As the spring structure for elastically supporting it is deleted, the structure is simplified and the layout is reduced.

상술한 본 발명에 대해서 구체적으로 설명하면, 연결포트(200)는 개통부(120)에 삽입되는 삽입부(220)가 형성되고, 삽입부(220)의 내측으로 이격되어 통로부(210)가 배치됨으로써 통로부(210)와 삽입부(220) 사이에 삽입공간(221)이 형성된다.When describing the present invention described above in detail, the connection port 200 has an insertion portion 220 inserted into the opening portion 120 is formed, and the passage portion 210 is spaced apart from the inside of the insertion portion 220 . By being disposed, the insertion space 221 is formed between the passage part 210 and the insertion part 220 .

도 1 내지 2에서 볼 수 있듯이, 연결포트(200)의 삽입부(220)는 하우징(100)의 개통부(120)에 삽입시 개통부(120)에 끼워짐으로써 연결포트(200)가 하우징(100)에 고정될 수 있다. 여기서, 삽입부(220)와 개통부(120) 사이에는 씰링링(R)이 구비될 수 있다. 또한, 연결포트(200)에는 개통부(120)에 삽입되는 삽입부(220)의 내측으로 통로부(210)가 이격되어 배치됨으로써, 통로부(210)와 삽입부(220) 사이에 삽입공간(221)이 형성된다. 이로 인해, 통로부(210)에 끼워지는 씰부재(300)가 유통로(211)와 삽입공간(221)을 통해, 통로부(210)를 따라 이동될 수 있다. 즉, 씰부재(300)는 조립부(310)가 통로부(210)에 끼워지며, 통로부(210)의 내측으로 유통로(211)가 형성되고 외측으로 삽입공간(221)이 형성됨에 따라 조립부(310)가 통로부(210)를 따라 이동될 수 있는 공간이 확보된다. 이렇게, 씰부재(300)는 통로부(210)를 따라 이동 가능함으로써, 밸브(500)의 회전시 또는 유체 흐름의 영향을 받을 경우 거동되어 씰부재(300)의 손상이 방지된다. 또한, 씰부재(300)는 탄성부재(400)에 의해 탄성 지지됨에 따른 유격 발생이 흡수되어 씰부재(300)의 위치가 고정되고 밸브(500)에 밀착상태를 유지할 수 있다.As can be seen in FIGS. 1 and 2 , the insertion part 220 of the connection port 200 is inserted into the opening part 120 when inserted into the opening part 120 of the housing 100 , so that the connection port 200 is connected to the housing. (100) can be fixed. Here, a sealing ring R may be provided between the insertion part 220 and the opening part 120 . In addition, in the connection port 200 , the passage part 210 is spaced apart from the inside of the insertion part 220 inserted into the opening part 120 , and thus an insertion space between the passage part 210 and the insertion part 220 . (221) is formed. For this reason, the seal member 300 fitted to the passage 210 may be moved along the passage 210 through the passage 211 and the insertion space 221 . That is, in the seal member 300 , the assembly part 310 is fitted into the passage part 210 , the flow passage 211 is formed on the inside of the passage part 210 and the insertion space 221 is formed on the outside of the passage part 210 . A space in which the assembly part 310 can be moved along the passage part 210 is secured. In this way, since the seal member 300 is movable along the passage portion 210 , it behaves when the valve 500 is rotated or is affected by a fluid flow, thereby preventing damage to the seal member 300 . In addition, the seal member 300 may absorb the occurrence of a gap due to being elastically supported by the elastic member 400 , so that the position of the seal member 300 is fixed, and a state in close contact with the valve 500 may be maintained.

한편, 도 3에 도시된 바와 같이, 조립부(310)는 통로부(210)의 내측면에 접촉되도록 연장된 제1접촉단부(311)와 통로부(210)의 외측면에 접촉되도록 연장된 제2접촉단부(312)로 구성되며, 제1접촉단부(311)와 제2접촉단부(312) 사이로 통로부(210)가 삽입될 수 있다.On the other hand, as shown in FIG. 3 , the assembly part 310 extends to contact the outer surface of the first contact end 311 and the passage part 210 to contact the inner surface of the passage part 210 . It is composed of a second contact end 312 , and a passage 210 may be inserted between the first contact end 311 and the second contact end 312 .

For this reason, when the sealing member 300 is installed in the passage part 210 , the sealing part 300 as the locking part 312a of the second contact end 312 is caught by the protrusion 213 of the passage part 210 . ) is not separated from the passage 210 . In particular, since the locking portion 312a is formed at the end of the second contact end 312 , the seal member 300 may move along the passage portion 210 by the extended length of the second contact end 312 . Here, the lower portion of the protrusion 213 is tapered and the upper portion of the locking portion 312a is tapered. As the tapered portion moves along the tapered portion of the protrusion 213 , assembly may be performed smoothly. The seal member 300 of the present invention may be made of a Teflon material, and is elastically deformed, so that the engaging portion 312a of the second contact end 312 passes over the protrusion 213 may be performed. .
