The plastic embedded valve (1) for rubber wheels according to the invention comprises: a hollow cylindrical valve body (2) made entirely of a plastic material; an actuating mechanism (3) arranged inside the valve body (2); a rubber ring (4) partially covering said valve body (2) and comprising an annular groove (45) behind which is a circumferentially projecting annular head (44). Characterised in that the valve body (2) extends within the rubber ring (4) up to the proximal end (12) of the valve (1), i.e. Up to an area that is radially compressed when the valve is intended to be mounted on the rim of a rubber wheel. Advantageously, the presence of the valve body ensures the optimal resistance of the proximal end to leakage from the rim bore caused by pressure thrust inside the rubber wheel.
根据本发明的用于橡胶轮的塑料嵌入式阀门(1)包括:完全由塑料材料制成的中空圆柱形阀体(2);布置在所述阀体(2)内部的致动机构(3);橡胶环(4),该橡胶环部分覆盖所述阀体(2)且包括环形槽(45),该环形槽后面是周向突出的环形头(44)。特征在于,阀体(2)在橡胶环(4)内延伸直至阀门(1)的近端(12),即,直到旨在将阀门安装至橡胶轮的轮缘上时径向压缩的区域。有利地,阀体的存在保证了近端对由橡胶轮内部的压力推力造成的从轮缘孔的泄漏的最佳阻力。
