The present invention relates to an urgent braking valve apparatus for a railway vehicle, capable of significantly improving the safety of a vehicle by performing quick and urgent braking even when a braking electronic control unit malfunctions or the railway vehicle fail in performing emergency braking, and enabling stable urgent braking by dividing low-speed driving and high-speed driving. The urgent braking valve apparatus includes: a valve body (100); a low-pressure formation part (200) installed in an upper part side of the inside of the valve body (100); a high-pressure formation part (300) installed in a lower part side of the inside of the valve body (100); an electronic control valve (400) mounted on one side of the valve body (100); and a check valve (500) installed in the valve body (100).

    본 발명은 제동전자제어유니트의 고장 또는 비상제동을 수행하지 못하는 경우에도 신속하게 긴급제동이 이루어져 차량의 안전성이 현저히 향상되도록 하고 저속운전시와 고속운전시를 구분하여 안정적인 긴급 제동이 이루어지도록 하는 철도 차량용 긴급제동밸브 장치에 관한 것으로, 본 긴급제동밸브 장치는 밸브본체(100)와, 상기 밸브본체(100)의 내부 상부측에 설치되는 저압형성부(200)와, 상기 밸브본체(100)의 내부 하부측에 설치되는 고압형성부(300)와, 상기 밸브본체(100)의 일측면에 장착되는 전자제어밸브(400)와, 상기 밸브본체(100)의 내부에 설치되는 역지밸브(500)를 포함한다.
