The invention provides a regulating valve, a retarder of a vehicle with the retarder and an engine cooling system. The regulating valve comprises a shell, a cover and a valve body; the shell is provided with a containing cavity, an opening communicated with the containing cavity, a first shell connecting port, a second shell connecting port and a third shell connecting port; the cover is used for closing the opening; and the valve body penetrates through the opening to be rotatably installed in the containing cavity, a valve body channel is formed in the valve body, a first valve body opening and a second valve body opening are formed in the valve body through the valve body channel, the valve body channel selectively communicates with the first shell connecting port and the second shell connecting port or communicates with the second shell connecting port and the third shell connecting port, the valve body channel comprises a middle section, the middle section forms a circular bent pipe, and the middle section is provided with an arc-shaped inner boundary and an arc-shaped outer boundary on the axial section of the middle section, and the circle center of the inner boundary and the circle center of the outer boundary are the same. According to the regulating valve and the cooling system, the flow resistance can be reduced while large flow is provided.
本申请提供一种调节阀和具有缓速器的车辆的缓速器和发动机冷却系统。调节阀包括壳体、盖以及阀体。壳体具有容腔以及与容腔连通的开口、第一壳体连接口、第二壳体连接口和第三壳体连接口。盖用于封闭开口。阀体穿过开口可转动地安装在容腔中,阀体上具有阀体通道,阀体通道在阀体上形成第一阀体口和第二阀体口,阀体通道可选择地连通第一壳体连接口和第二壳体连接口或连通第二壳体连接口和第三壳体连接口,阀体通道包括中间段,中间段形成圆形弯管,并且其中,在中间段的轴向截面上,中间段具有圆弧形的内边界和外边界,内边界和外边界的圆心相同。本申请提供的调节阀和冷却系统能够在提供大流量的同时降低流动阻力。
