The invention relates to a hand brake valve which comprises a first valve body and a second valve body, the first valve body can be used for communicating the hand brake valve with an external air path, and at least the first valve body is made of plastic. One of the first valve body and the second valve body is provided with a first positioning protrusion protruding towards the other one of the first valve body and the second valve body, and the other one of the first valve body and the second valve body is provided with a second positioning protrusion protruding inwards in the radial direction relative to the inner wall of the first valve body and the second valve body. The first positioning protrusion and the second positioning protrusion can tightly abut against each other in the radial direction, and therefore relative movement between the first valve body and the second valve body in the radial direction is limited. At least part of the structure of the hand brake valve is made of plastic, and the hand brake valve is provided with the positioning mechanism suitable for plastic materials, so that the hand brake valve is light in weight and low in cost, meanwhile, the first valve body and the second valve body can be accurately positioned relative to each other, and the strength requirement can be met at the same time.
本发明涉及一种手制动阀,其包括第一阀体和第二阀体,第一阀体能够用于将所述手制动阀和外部气路连通,并且至少第一阀体由塑料制成。第一阀体和第二阀体中的一个设置有朝向第一阀体和第二阀体中的另一个突出的第一定位凸起,第一阀体和第二阀体中的另一个设置有相对于其内壁径向向内突出第二定位凸起,第一定位凸起和第二定位凸起能够沿径向方向紧密地彼此贴靠,从而限制第一阀体和第二阀体之间在径向方向上的相对移动。本发明的手制动阀的至少部分结构由塑料制成,并具有适用于塑料材质的定位机构,使得在手制动阀具有较轻的重量和较低的成本的同时,也能够使第一阀体和第二阀体准确地相对于彼此定位,并能够同时满足强度要求。
