Abstract

PURPOSE: A cap of a radiator is provided to prevent blow-off of hot coolant and burn in opening the cap by decreasing internal pressure with a safety cock installed in the radiator cap in increasing pressure of the radiator. CONSTITUTION: A radiator(10) is sealed by a radiator cap(20), and a pressure valve(30) and a vacuum valve(40) are arranged in the radiator cap. A shaft rod(60) is contacted to the vacuum valve and inserted with penetrating the radiator cap. The shaft rod is connected to an operating rod(70) by a pin shaft(72). High pressure of the radiator is moved into an auxiliary tank with lifting the pressure valve by the end of the shaft rod in turning the operating rod. Blow-off of hot coolant or burn is prevented with reducing the internal pressure of the radiator by the safety cock.

Description

라디에이터 뚜껑Radiator lid

본 발명은 라디에이터(Radiator)에 관한 것으로, 더욱 상세하게는 라디에이터 뚜껑(Radiator Cap)에 안전콕크를 설치하여 뚜껑을 열더라도 뜨거운 냉각수가 분출되는 것을 방지할 수 있도록 개량한 것이다.The present invention relates to a radiator, and more particularly, to install a safety cock on the radiator cap (radiator cap) to improve the hot water can be prevented even if the lid is opened.

자동차의 라디에이터(10)를 밀봉시키도록 된 라디에이터 뚜껑(20)에는 압력밸브(30)와 진공밸브(40)가 병설되어 엔진 운동중 냉각계통내에 생긴 압력을 유지하는 것으로, 냉각수가 100∼120℃ 정도로 올라가 압력이 1.3∼2.0kgf/㎠이 되면도1과 같이 압력밸브(30)를 상부 측으로 밀어 올려 보조탱크와 연결된 오버 플로파이프(50)를 통해 외기로 압력이 빠져나가도록 되고, 반대로 엔진의 온도가 낮아져 라디에이터(10) 내부의 압력이 대기압보다 낮아지면 도2와 같이 진공밸브(40)가 열리면서 보조탱크의 냉각수를 라디에이터(10)로 유입시켜 부압을 없게하므로써 대기압에 의해 라디에이터가 파손되는 것을 예방하고 있다.In the radiator cap 20 to seal the radiator 10 of the vehicle, a pressure valve 30 and a vacuum valve 40 are installed together to maintain the pressure generated in the cooling system during engine movement. When the pressure rises to about 1.3 to 2.0 kgf / cm 2, the pressure valve 30 is pushed upward to the upper side as shown in FIG. 1, and the pressure is released to the outside air through the overflow pipe 50 connected to the auxiliary tank. When the temperature inside the radiator 10 becomes lower than the atmospheric pressure because the temperature is lowered, the vacuum valve 40 opens as shown in FIG. 2 and the cooling water of the auxiliary tank flows into the radiator 10 so that the radiator is not damaged by atmospheric pressure. It is preventing.

하지만 종래에는 라디에이터 뚜껑(20)에 병설되는 압력밸브(30)와 진공밸브(40)에 의해 라디에이터(10)의 압력을 자동적으로 조절 유지할 수 있는 이점은 있었으나, 주행 후 차랑으로부터 냉각수를 보충하거나 기타의 경우 라디에이터 뚜껑(20)을 열게 되는 경우 뜨거운 냉각수가 분출되어 화상을 입게되는 경우가 종종 있었다.However, in the related art, the pressure of the radiator 10 may be automatically adjusted and maintained by the pressure valve 30 and the vacuum valve 40 installed in the radiator cap 20, but the coolant may be replenished from the vehicle after driving or the like. In the case of opening the radiator cap 20, hot coolant is often ejected and burned.

이에 본 발명에서는 상기한 바와 같은 종래의 문제점을 해소하기 위해, 라디에이터 뚜껑에 안전콕크를 설치하여 엔진이 뜨거워져 라디에이터의 압력이 높은 경우 안전콕크를 이용하여 내부 압력을 줄일 수 있게 함으로써 뚜껑을 열더라도 종래와 같이 뜨거운 냉각수가 분출되는 일이 없도록 함에 그 목적이 있는 것인바, 이를 첨부된 예시 도면을 참고하여 그 구성 및 작용 효과 등을 보다 구체적으로 설명하면 다음과 같다.Therefore, in the present invention, in order to solve the conventional problems as described above, by installing a safety cock on the radiator cap to heat the engine when the pressure of the radiator is high so that the internal pressure can be reduced by using a safety cock to open the lid The purpose is to prevent the hot coolant is not ejected as in the prior art, with reference to the accompanying drawings illustrating the configuration and operation effects, etc. in more detail as follows.

도3,4는 본 발명에 따른 라디에이터 뚜껑의 작동관계를 나타낸 예시도,3 and 4 is an exemplary view showing the operating relationship of the radiator cap according to the present invention,

도3에 나타낸 바와 같이 본 발명은 라디에이터(10)를 밀봉하는 라디에이터 뚜껑(20)에 압력밸브(30)와 진공밸브(40)가 병설되는 것에 있어서, 상기진공밸브(40)와 접촉하도록 뚜껑(20)에 관통되게 축봉(60)이 끼워지고, 상기 축봉(60)의 일측단은 스프링(80)의 탄성을 보유한 채 압력밸브(30)에 설치한 브라켓(32)에 고정되고, 타측단은 작동간(70)과 핀축(72)으로 연결되어 상기 작동간(70)을 회동(바로세우면)시킴에 따라 작동간(70) 선단이 캡(20)의 상면을 누르면서 축봉(60)을 상부측으로 이동시킴에 따라 압력밸브(30)가 개방되는 구성으로 되고 있다.As shown in FIG. 3, in the present invention, when the pressure valve 30 and the vacuum valve 40 are installed in the radiator cap 20 which seals the radiator 10, the lid is in contact with the vacuum valve 40. The shaft rod 60 is fitted to penetrate through 20, and one end of the shaft rod 60 is fixed to the bracket 32 installed on the pressure valve 30 while retaining the elasticity of the spring 80. It is connected by the operation shaft 70 and the pin shaft 72 so that the operation shaft 70 is rotated (upright), while the tip of the operation shaft 70 presses the upper surface of the cap 20 while the shaft 60 is moved upward. The pressure valve 30 is opened as it moves.

이와 같이 구성된 본 발명은 라디에이터 뚜껑(20)을 열고자 할 경우에는 도4에 나타낸 바와 같이 뚜껑(20)에 나란하게 누워 있는 작동간(70)을 90° 회전시켜 뚜껑(20)과 직교되게 바로 세우면, 축봉(60)은 스프링(80)을 압축시키면서 상부측으로 들어 올려지게 되고, 이때 축봉(60)에 고정된 브라켓(32)은 축봉(60)과 함께 상승하게 되어 압력밸브(30)를 들어올려 개방시키고, 압력밸브(30)가 개방 되어짐에 따라 상대적으로 높은 압력을 형성하는 라디에이터(10)의 압력은 오버플로파이프(50)를 통해 그 보다 낮은 압력을 이루는 보조탱크로 흐르게 되어 라디에이터(10)의 내부 압력은 줄일 수 있게 된다.When the present invention configured as described above is to open the radiator cap 20, as shown in Figure 4 by rotating the operation 70 lying side by side on the lid 20 by 90 ° immediately orthogonal to the lid 20 When raised, the shaft 60 is lifted to the upper side while compressing the spring 80, the bracket 32 fixed to the shaft 60 is raised with the shaft 60 to lift the pressure valve 30 As the pressure valve 30 is opened, the pressure of the radiator 10 forming a relatively high pressure flows through the overflow pipe 50 to the auxiliary tank forming a lower pressure. ) The internal pressure can be reduced.

따라서 뚜껑(20)을 열더라도 라디에이터의 뜨거운 냉각수가 분출되는 일이 없게 된다.Therefore, even if the lid 20 is opened, the hot cooling water of the radiator is not ejected.

한편, 냉각수를 모두 보충한 후에는 다시 라디에이터(10)에 뚜껑(20)을 닫은 후 이제까지 입형으로 세워진 작동간(70)을 도3에 나타낸 바와 같이 90° 회전시키면 작동간(70)은 뚜껑(20)의 상면에 나한하게 옆으로 뉘우면 이제까지 축봉(60)을 잡아당기는 인장력이 해제되어 작동간(70)과 연결된 축봉(60)은 스프링(80)의 탄성복원력에 의해 하부측으로 하강하게 되고, 축봉(60)이 하강함에 따라 압력밸브(30) 또한 스프링의 복원력에 의해 초기 위치로 복귀하며 압력밸브(30)를 닫게 된다.On the other hand, after replenishing all of the coolant, close the lid 20 to the radiator 10 again and rotate the operation rod 70, which has been standing upright as shown in FIG. 3, by 90 degrees as shown in FIG. When lie sideways to the upper surface of 20), the tension force pulling ever the shaft 60 is released so that the shaft 60 connected to the operation period 70 is lowered to the lower side by the elastic restoring force of the spring 80, As the rod 60 descends, the pressure valve 30 also returns to its initial position by the restoring force of the spring and closes the pressure valve 30.

이상에서와 같이 본 발명에 의하면, 라디에이터 뚜껑에 안전콕크를 설치하여 라디에이터의 압력이 높은 경우 안전콕크를 이용하여 내부 압력을 줄일 수 있게하으로써 뚜껑을 열더라도 종래와 같이 뜨거운 냉각수가 분출되는 일이되어 화상의 염려가 없는 등의 효과가 있게 된다.As described above, according to the present invention, when the pressure of the radiator is installed by installing a safety cock on the radiator cap to reduce the internal pressure by using a safety cock, even if the lid is opened, hot coolant is ejected as in the prior art. The effect is that there is no fear of burns.
