Abstract

본 발명은 에어 브레이크에 에어를 공급하는 에어탱크와 연설된 조절 밸브에 설치되는 드레인 코크의 자동개폐장치에 관한 것이다.The present invention relates to an air tank for supplying air to an air brake and an automatic opening / closing device of a drain coke installed in a regulated control valve.

그 기술적인 구성은, 에어탱크와 연설된 조절밸브(1)의 내측으로 상하측에 0-링(3)(3')이 착설된 피스톤(2)이 스프링(5)에 탄설되고, 상기 피스톤(2)의 중앙에는 결합바아(10)가 설치되어 이에 차폐판(6) 및 그 하단에 드레인 코크(7)가 설치되는 한편, 피스톤(2)의 하측으로 밀폐실(8)이 형성되고, 상기 밀폐실(8)의 하측 중앙에는 드레인 코크(7)의 하단이 당접하는 요홈부(9)가 마련되어 드레인 밸브와 연동연결 되는 것이다.The technical configuration is that the piston (2) with 0-rings (3) and (3 ') installed on the upper and lower sides of the control valve (1) extended to the air tank is installed in the spring (5), and the piston A coupling bar 10 is installed at the center of (2) so that a shield plate 6 and a drain cock 7 are installed at the lower end thereof, while a sealed chamber 8 is formed below the piston 2. The lower center of the sealed chamber 8 is provided with a recess 9 in which the lower end of the drain cock 7 is in contact with the drain valve.

이에 따라서, 에어탱크 내부로 유입되는 대기중의 공기 압축시 발생되는 응축수를 조절 밸브내의 압력차에 의해 용이하게 배출함은 물론, 상기 응축수의 배출작용이 자동적으로 이루어질 수 있게 되는 것이다.Accordingly, the condensed water generated during the compression of air in the air introduced into the air tank can be easily discharged by the pressure difference in the control valve, and the discharge action of the condensed water can be automatically performed.
