The invention relates to the field of electric control braking, in particular to a control valve for a braking system, a control valve assembly with the control valve and the braking system. The valve body assembly comprises a valve body, and the valve body comprises a valve seat and a sealing seat; the valve body is provided with a flow channel. The flow channel is a stepped channel; through the design of the stepped flow channel, when a booster pump system pressurizes a brake master cylinder and brake fluid flows through the stepped flow channel, due to sudden channel size change, the oil fluid entering the control valve cannot directly and smoothly flow out and can be accumulated in a main flow channel to form a stable pressure difference; subsequent pressure difference can be acquired through a pressure sensor in the brake system, and then in subsequent use, the sealing performance of the brake master cylinder or the brake system is judged according to the pressure value corresponding to the pressure difference P at the specified push speed V.
本发明涉及电控制动领域,具体来说是一种制动系统用控制阀及具体该控制阀的控制阀总成和制动系统,包括阀体总成;所述阀体总成包括阀体本体,所述阀体本体包括阀座以及密封座;所述阀体本体上设有流量通道;所述流量通道为阶梯型通道;本发明通过阶梯型的流量通道设计,在增压泵系统向制动主缸增压时,制动液流经阶梯型流量通道时,由于突然间的通道尺寸变化,使得进入控制阀内的油液不能直接顺畅流出,会在主流通道积聚形成稳定的压力差,后续该压力差可通过制动系统内的压力传感器采集获的,进而在后续使用时,根据指定推速V下压力差△P对应的压力值来判定制动主缸或制动系统的密封性。
