자동차의 공기브레이크용 공기탱크의 체크밸브Check valve of air tank for automobile air brake

본 발명은 자동차의 공기브레이크용 공기탱크의 체크밸브에 관한 것으로, 특히 체크밸브의 내부구조가 변경되어 각각의 공기탱크로 공급되는 압축공기의 역류현상이 제거됨은 물론, 브레이크라인의 파손시 공기탱크내의 압축공기가 외부로 누설되는 것이 방지되도록 된 자동차의 공기브레이크용 공기탱크의 체크밸브에 관한 것이다.The present invention relates to a check valve of an air tank for an air brake of an automobile, and in particular, the internal structure of the check valve is changed so that the backflow phenomenon of the compressed air supplied to each air tank is eliminated, as well as the air tank in case of breakage of the brake line. The present invention relates to a check valve of an air tank for an air brake of a vehicle in which compressed air inside is prevented from leaking to the outside.

일반적으로 제동장치(Brake System)는 주행하는 자동차를 감속 또는 정지시킴과 동시에 주차상태를 유지하기 위해 사용하는 중요한 장치로서, 첫째, 작동이 확실하고 잘되어야 하고, 둘째, 신뢰성과 내구성이 뛰어나야 하며, 세째, 점검 및 조정이 용이해야 하는 조건을 갖추어야 한다. 제동장치의 기본적인 구조는 운전자의 조작력을 링크나 유압을 이용해서 전달하는 조작기구와 그 힘을 받아 제동력을 발생하는 본체로 되어 있으며, 주행할 때 주로 사용하는 주브레이크와 자동차를 주차할 때 사용하는 주차브레이크가 있는 바, 상기 주브레이크는 운전자의 발로 조작하기 때문에 푸트브레이크라 하고, 상기 주차브레이크는 보통 손으로 조작하기 대문에 핸드브레이크라 한다.In general, a brake system is an important device used to maintain a parking state at the same time as decelerating or stopping a driving car. Firstly, it must be reliable and well operated, and secondly, it must be reliable and durable. Third, conditions should be easy to check and adjust. The basic structure of the braking system consists of a control mechanism that transmits the driver's operating force by using a link or hydraulic pressure, and a main body that generates the braking force by receiving the force. Since there is a parking brake, the main brake is called a foot brake because it is operated by the driver's foot, and the parking brake is usually called a hand brake because it is operated by hand.

그리고, 상기 주브레이크는 브레이크페달의 조작에 의해 발생된 유압을 매개로 제동시키도록 된 유압식 브레이크와, 대형자동차 등 큰 제동력을 필요로 하는 경우에 사용하도록 된 배력식 브레이크 및 , 압축공기의 압력을 이용해 제동력을 발생시키도록 된 공기브레이크로 분류된다.In addition, the main brake is a hydraulic brake to be braked by the hydraulic pressure generated by the operation of the brake pedal, a hydraulic brake to be used when a large braking force such as a large vehicle is required, and the pressure of the compressed air It is classified as an air brake intended to generate braking force.

또한, 상기 공기브레이크는 공기탱크와, 기관의 타이밍기어로 구동되어 압축공기를 생성하도록 된 공기압축기와, 브레이크페달로 조작함과 더불어 페달을 밟는 정도에 맞는 공기의 압력을 후술하는 릴레이밸브로 보내도록 된 브레이크밸브와, 이 브레이크밸브에서 오는 공기압력으로 작동되어 브레이크작동이 지연되는 것을 방지하도록 된 릴레이밸브와, 이 릴레이밸브에서 오는 공기압을 받아 제동력을 발생시키도록 된 브레이크체임버 및 상기 공기탱크안의 공기압을 조정하도록 된 압력조정기로 이루어진다.In addition, the air brake is an air tank, an air compressor driven by a timing gear of the engine to generate compressed air, and a brake pedal, which is operated by a brake pedal, and sends a pressure of air corresponding to a pedal step to a relay valve to be described later. Of the brake valve, the relay valve which is operated by the air pressure from the brake valve to prevent the brake operation from being delayed, the brake chamber which is configured to generate the braking force by receiving the air pressure from the relay valve, and the air tank. It consists of a pressure regulator adapted to adjust the air pressure.

여기서, 상기 공기탱크는 도 1 에 도시된 바와 같이, 전방계통의 압축공기를 공급하도록 된 앞탱크(100)와, 후방계통으로 압축공기를 공급하도록 된 뒤탱크(200)와, 압축기에서 보내는 압축공기 속의 수분을 제거하도록 된 탈수탱크(300)와, 주차시 사용되도록 된 주차용탱크(400) 및, 상기한 탱크들(100, 200, 300, 400)을 보조하도록 된 리저브탱크(500)로 이루어져 있다.Here, the air tank is, as shown in Figure 1, the front tank 100 to supply the compressed air of the front system, the back tank 200 to supply the compressed air to the rear system and the compression sent from the compressor Dehydration tank 300 to remove moisture in the air, the parking tank 400 to be used for parking, and the reserve tank 500 to assist the tanks (100, 200, 300, 400) consist of.

이러한, 상기 탱크들(100, 200, 300, 400, 500)에는 동일한 구조의 체크밸브(10, 20, 30, 40, 50)가 각각 장착되어져, 상기 탱크(100, 200, 300, 400, 500)로 출입되는 압축공기를 제어하였으나, 종래의 상기 체크밸브(10, 20, 30, 40, 50)는 단순한 구조를 지님으로 인해 각각의 탱크(100, 200, 300, 400, 500)로 공급되는 압축공기의 역류현상을 제어하지 못할 뿐만 아니라 브레이크라인의 파손시 상기 탱크(100, 200, 300, 400, 500)내의 압축공기가 외부로 누설되는 것을 차단하지 못하는 문제점이 있었다.The tanks 100, 200, 300, 400, and 500 are equipped with check valves 10, 20, 30, 40, and 50 of the same structure, respectively, so that the tanks 100, 200, 300, 400, 500 are equipped with the same. Although the compressed air entering and exiting the control valve is controlled, the conventional check valves 10, 20, 30, 40, and 50 are simply supplied to the respective tanks 100, 200, 300, 400, and 500 because they have a simple structure. Not only the backflow phenomenon of the compressed air was not controlled, but there was a problem in that the compressed air in the tanks 100, 200, 300, 400, and 500 could not be prevented from leaking to the outside when the brake line was broken.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 체크밸브의 내부구조를 변경하여 각각의 탱크로 공급되는 압축공기의 역류현상을 방지함은 물론, 브레이크라인의 파손시 탱크내의 압축공기가 외부로 누설되는 것을 차단하도록 된 자동차의 공기브레이크용 공기탱크의 체크밸브를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by changing the internal structure of the check valve to prevent the backflow of the compressed air supplied to each tank, as well as the compressed air in the tank when the break line breaks It is an object of the present invention to provide a check valve of an air tank for an air brake of a vehicle, which is configured to block leakage of gas to the outside.

상기와 같은 목적을 달성하기 위한 본 발명의 체크밸브가, 소정형상으로 형성된 케이스, 이 케이스의 내측면에 배설되어 가이드 역할을 수행하도록 된 다이아프램, 이 다이아프램을 따라 상기 케이스내에서 이동되도록 된 셔틀밸브, 상기 케이스의 일측부에 배설되어 밀봉역할을 수행하도록 된 오형-링으로 구성된다.Check valve of the present invention for achieving the above object, a case formed in a predetermined shape, a diaphragm disposed on the inner surface of the case to serve as a guide, the diaphragm to be moved in the case along the diaphragm Shuttle valve, it is composed of a mold-ring disposed on one side of the case to perform a sealing role.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2 는 본 발명에 따른 체크밸브가 장착된 상태를 나타내는 단면도로서, 본 발명은, 소정형상으로 형성되어 일측부는 탱크(100)의 외측에 타측부는 상기 탱크(100)의 내측에 배설되도록 케이스(11)와, 이 케이스(11)의 일측 내벽에 배설되어 가이드역할을 수행하도록 된 다이아프램(12)과, 이 다이아프램(12)을 따라 상기 케이스(11)내에서 이동되어 입구를 개폐하도록 된 셔틀밸브(13) 및, 상기 케이스(11)의 일측 끝단에 배설되어 기밀을 유지하도록 된 오형-링(14)으로 이루어진다.Figure 2 is a cross-sectional view showing a state in which the check valve is mounted according to the present invention, the present invention is formed in a predetermined shape so that one side is the outer side of the tank 100 and the other side is disposed inside the tank 100 (11), a diaphragm 12 disposed on one inner wall of the case 11 to perform a guide role, and moved in the case 11 along the diaphragm 12 to open and close an entrance. Shuttle valve 13 and the mold-ring 14 is disposed at one end of the case 11 to maintain the airtight.

따라서 공기압축기에서 압축공기가 배출되어 체크밸브(10)로 도달되면, 상기 압축공기의 공기압에 의해 셔틀밸브(13)가 다이아프램(12)을 따라 우측으로 이동되어 상기 체크밸브(10)의 입구가 개방되므로 압축공기는 탱크(100)의 내부로 용이하게 유입되며, 이때 오형-링(14)의 기밀에 의해 압축공기의 역류현상을 방지할 수 있게 된다.Therefore, when compressed air is discharged from the air compressor and reaches the check valve 10, the shuttle valve 13 is moved to the right along the diaphragm 12 by the air pressure of the compressed air, thereby inleting the check valve 10. Since the compressed air is easily introduced into the inside of the tank 100, at this time, it is possible to prevent the backflow of the compressed air by the airtight of the mold ring (14).

또한, 교통사고 내지 정기점검의 미숙으로 브레이크라인이 파손시 셔틀밸브(13)의 이동으로 인해 체크밸브(10)의 입구가 밀폐되므로 탱크(100)내의 압축공기가 외부로 누설되는 것을 방지할 수 있게 된다.In addition, since the inlet of the check valve 10 is sealed due to the movement of the shuttle valve 13 when the brake line is damaged due to traffic accident or immature inspection, the compressed air in the tank 100 can be prevented from leaking to the outside. Will be.

이상 설명한 바와 같이 본 발명에 의한 체크밸브가, 소정형상으로 형성된 케이스, 이 케이스 내측면에 배설되어 가이드역할을 수행하도록 된 다이아프램과, 이 다이아프램을 따라 상기 케이스내에서 이동되도록 된 셔틀밸브, 상기 케이스의 일측부에 배설되어 밀봉역할을 수행하도록 된 오형-링으로 이루어져, 공기압축기에서 탱크로 공급되는 압축공기의 역류현상이 방지될 뿐만 아니라 브레이크라인의 파손시 탱크내의 압축공기가 외부로 누설되는 것이 차단되는 효과가 있다.As described above, the check valve according to the present invention includes a case formed in a predetermined shape, a diaphragm disposed on the inner surface of the case to perform a guide role, a shuttle valve moved in the case along the diaphragm, Consists of an inverted-ring disposed on one side of the case to perform a sealing role, preventing backflow of the compressed air supplied to the tank from the air compressor, as well as preventing the compressed air in the tank from leaking outside when the brake line breaks. Being blocked has the effect.
