본 발명은 에어 브레이크 시스템의 급속해제밸브에 관한 것으로, 더욱 상세하게는 에어의 공급과 배기시에 체크밸브의 기능을 하는 다이어프램에 엠보싱을 형 성하여 작동에어의 급속배기효율을 증대시킴과 아울러 브레이크 작동시 에어의 급속한 흐름에 의해 소음이 발생되는 것을 현저하게 저감하는 에어 브레이크 시스템의 급속해제밸브에 관한 것이다.The present invention relates to a quick release valve of an air brake system, and more particularly, embossing is formed on a diaphragm that functions as a check valve when supplying and exhausting air, thereby increasing the rapid exhaust efficiency of the operating air and braking. The present invention relates to a quick release valve of an air brake system that significantly reduces noise generated by a rapid flow of air during operation.

일반적으로, 종래의 급속해제밸브는 듀얼브레이크 밸브나 다른 에어공급원으로부터 공급된 에어를 다이어프램을 통하여 브레이크 챔버에 공급하고, 브레이크의 해제시에 급속으로 대기중에 방출하는 역할을 수행한다. In general, the conventional quick release valve serves to supply the air supplied from the dual brake valve or other air supply to the brake chamber through the diaphragm, and rapidly releases the air to the atmosphere when the brake is released.

이 결과 배기포트를 통하여 대기중으로 배출되는 고압의 에어는 필연적으로 고음의 소음을 발생하게 되며, 브레이크의 해제속도는 급속해제밸브의 배기 포트쪽 오리피스의 크기에 의해서 좌우된다. As a result, the high-pressure air discharged into the atmosphere through the exhaust port inevitably generates high noise, and the release speed of the brake depends on the size of the orifice on the exhaust port side of the quick release valve.

즉, 종래 급속해제밸브의 구성을 도 1에서 보면, 상부와 하부가 분리되어 결합구조를 갖는 밸브몸체(100) 및 커버(100')와, 상기 커버(100')에는 서플라이 포트(110)가, 밸브몸체(100)에는 서플라이 포트(110)로부터 브레이크 작동에어를 공급받는 공급포트(120)가 양측으로 형성되고, 상기 서플라이 포트(110)와 수직으로 마주하는 위치의 밸브몸체(100)에는 브레이크 해제시 잔류에어를 배출하는 배기포트(150)가 형성된다. That is, in the configuration of the conventional quick release valve in Figure 1, the upper and lower parts are separated from the valve body 100 and the cover 100 'having a coupling structure and the cover 100', the supply port 110 is The valve body 100 has a supply port 120 that receives the brake operation air from the supply port 110 on both sides, and a brake is provided on the valve body 100 at a position facing the supply port 110 vertically. An exhaust port 150 for discharging residual air is formed at the time of release.

상기 밸브몸체(100)와 커버(100')간의 결합부분에는 서플라이 포트(110)로부터의 브레이크 작동에어가 공급포트(120)로 공급하거나 또는 잔류에어를 배기포트(150)로 배기되도록 체크밸브 역할을 하는 다이어프램(130)이 개재되고, 상기 다이어프램(130)의 상부에는 그 다이어프램(130)의 밀착력을 높이기 위한 푸쉬러버(140)가 가압상태로 설치된다. The coupling portion between the valve body 100 and the cover 100 ′ acts as a check valve so that the brake operating air from the supply port 110 supplies the supply port 120 or exhausts residual air to the exhaust port 150. The diaphragm 130 is interposed, and the push rubber 140 for increasing the adhesion of the diaphragm 130 is installed in the upper portion of the diaphragm 130 in a pressurized state.

그러나, 이러한 종래의 급속해제밸브에서의 다이어프램은 커버의 내부단면과 면접촉상태로 이루어져 있기 때문에 접촉면적이 넓어 브레이크 작동에어가 공급포트로 공급되기 위한 신속한 작동이 어렵다는 단점이 있다. However, since the diaphragm of the conventional quick release valve is made in surface contact with the inner end surface of the cover, the contact area is wide, so that the brake operation air is not quickly operated to be supplied to the supply port.

또한, 종래의 급속해제밸브는 공급포트로 작동에어가 공급되는 과정과 배기포트를 통한 에어 배출시 필연적으로 고음의 소음이 발생되는 문제점이 있다. In addition, the conventional quick release valve has a problem that a high noise noise is inevitably generated during the process of supplying the operating air to the supply port and the air discharge through the exhaust port.

따라서, 본 발명은 상기의 문제점을 해결하기 위해 창출된 것으로서 그 목적은, 다이어프램의 상부에 그 다이어프램과 동심을 갖는 다수의 엠보싱을 형성하고, 상기 다이어프램과 커버의 단면이 면접촉이 아닌 선접촉으로 결합되도록 하여 서플라이 포트로부터 공급포트로 흐르는 브레이크 작동에어의 흐름을 더욱 신속하게 하는 에어 브레이크 시스템의 급속해제밸브를 제공함에 있다. Accordingly, the present invention has been made to solve the above problems, the object of which is to form a plurality of embossing concentric with the diaphragm on the upper portion of the diaphragm, the cross-section of the diaphragm and the cover in line contact rather than surface contact It is to provide a quick release valve of the air brake system to be coupled to make the flow of the brake operating air flowing from the supply port to the supply port more quickly.

또한, 본 발명의 다른 목적 즉, 다이어프램을 통한 에어의 흐름시 발생되는 고음의 소음을 저감시키기 위해 배기포트에 소음차단구조를 구성하는 에어 브레이크 시스템의 급속해제밸브를 제공함에 있다. Another object of the present invention is to provide a quick release valve of an air brake system constituting a noise blocking structure in an exhaust port in order to reduce high-pitched noise generated when air flows through a diaphragm.

상기 목적을 달성하기 위한 본 발명은, The present invention for achieving the above object,

서플라이 포트를 갖는 커버와, 상기 커버와의 결합시 서플라이 포트로부터의 브레이크 작동에어가 유입될 수 있는 공급포트 및 잔류에어의 배출을 위한 배기포트가 형성된 밸브몸체와, 상기 커버와 밸브몸체의 결합부분에 작동에어의 공급흐름 및 배기흐름을 제어하는 다이어프램이 개재된 에어 브레이크 시스템의 급속해제밸 브에 있어서, A valve body having a cover having a supply port, a supply port through which the brake actuating air from the supply port can be introduced when the cover port is engaged, and an exhaust port for discharging residual air, and an engaging portion of the cover and the valve body In the quick release valve of the air brake system with a diaphragm for controlling the supply flow and exhaust flow of the air operated air,
