The invention discloses a control method for a pressure regulating mechanism of a buffer cavity of a brake valve, which comprises the following steps of: acquiring an adjusting instruction which is sent from a client; a motor is controlled to rotate according to the adjusting instruction, the motor is used for driving an adjusting rod on the brake valve buffer cavity pressure adjusting mechanism to rotate, and the adjusting rod moves in the axial direction in the rotating process so as to adjust the position of an elastic telescopic piece or adjust the elastic deformation amount of the elastic telescopic piece. The elastic telescopic piece is arranged in the brake valve buffer cavity pressure regulating mechanism and matched with the air valve to open or close a channel entering the buffer cavity. The buffer cavity is formed in the brake valve and located on the lower side of the brake piston, and air pressure in the buffer cavity is used for increasing downward moving resistance of the brake piston. According to the invention, the client sends the instruction to drive the motor to rotate, so that the air pressure required for driving the air valve to be closed is adjusted, and the adjustment of the braking proportion and the braking performance of the braking valve is conveniently realized.

    本发明公开了制动阀缓冲腔调压机构的控制方法,包括如下步骤:获取调整指令,其中,调整指令从客户端发出;根据调整指令控制电机转动,其中,电机用以驱动制动阀缓冲腔调压机构上的调节杆转动,调节杆在转动过程中沿轴向方向移动以调整弹性伸缩件的位置或调整弹性伸缩件的弹性形变量,弹性伸缩件设置在制动阀缓冲腔调压机构内并与气门阀配合以导通或关闭进入缓冲腔内的通道;缓冲腔设置在制动阀内并位于制动活塞的下侧,缓冲腔内的气压用以增大制动活塞的下移阻力。本发明通过客户端发送指令带动电机转动,从而调整了驱动气门阀关闭时所需的气压的大小,方便的实现了制动阀的制动比例及制动性能的调节。
