The invention belongs to the field of drain valves, and discloses a drain valve for an air cylinder of a heavy-duty car, which is characterized by comprising a locking bolt (1), a pressure spring (2), a retainer ring (3), a cock (4), an upward moving guide rail (6) and a cock slide rail (7), a vertically-through cavity is formed in the locking bolt (1), and the upper end and the lower end of the cavity are each provided with a radial flange extending inwards. The check ring (3) is fixedly arranged in the cavity and attached to the radial flange at the upper end of the cavity, and the cock (4) is arranged in the cavity. The drain valve for the air cylinder of the heavy-duty car has the following advantages that a driver only needs to screw the cock by a certain angle, the drain valve can continuously exhaust air without any operation, and the operation convenience of the driver is improved; due to the double design of the sealing ring and the compression spring, the reliability is improved, and the air leakage phenomenon is not prone to occurring.

    本发明属于排水阀领域,公开了一种用于重型汽车储气筒的排水阀,其特征在于,包括锁紧螺栓(1)、压紧弹簧(2)、挡圈(3)、旋塞(4)、上移导轨(6)和旋塞滑轨(7);所述锁紧螺栓(1)内部开设有上下贯通的腔体,所述腔体的上下两端均设置有向内延伸的径向凸缘;所述挡圈(3)固定设置在腔体内部与腔体上端的径向凸缘贴合,所述旋塞(4)设置在腔体中。本发明的用于重型汽车储气筒的排水阀具有以下优点:驾驶员只需要将旋塞旋拧一定的角度,无需任何操作可使排水阀进行持续排气,提高驾驶员的操作便利性;密封圈和压紧弹簧的双重设计,提高了可靠性,不容易出现漏气现象。
