The invention relates to a manual control valve exhaust nozzle which comprises a base and a connector, the base is used for being connected with a manual control valve, and the connector is used for being connected with an exhaust pipe in a sleeved mode. The rear end of the connector is connected with the base, and a damping ring and a vacuum ring are sequentially arranged on the outer wall of the connector from front to back. The damping ring and the vacuum ring protrude out of the outer wall of the connector. A vacuum storage area is formed between the damping ring and the vacuum ring; by arranging the damping ring and the vacuum ring, the technical scheme combination of interference resistance and vacuum resistance is completed, the anti-loosening effect of exhaust pipe installation is improved, under the interference resistance of the vacuum ring, the exhaust pipe in a vacuum storage area tends to be straightened, at the moment, vacuum resistance appears on a rubber pipe and a transition face, and the larger the external force for pulling the exhaust pipe is, the larger the vacuum resistance is, the larger the external force for pulling the exhaust pipe is. The larger the rubber deformation is, the larger the vacuum degree generated by the vacuum storage area is, the larger the converted vacuum resistance is, no clamp needs to be additionally arranged, and the material object cost and the clamp installation cost are saved.

    本发明涉及一种手控阀排气嘴,包括底座和接头,所述底座用于连接手控阀,所述接头用于套接排气管;所述接头的后端连接所述底座,所述接头外壁由前向后依次设置有阻尼环和真空环;所述阻尼环和所述真空环均凸出于所述接头的外壁;所述阻尼环和所述真空环之间形成真空储备区域;本发明通过设置阻尼环和真空环完成了过盈阻力加真空阻力的技术方案组合,提高了排气管安装的防松效果,在真空环的过盈阻力下,真空储备区域内的排气管会有拉直趋势,此时橡胶管与过渡面将出现真空阻力,扯动排气管的外力越大,橡胶变形也越大,由真空储备区域产生的真空度也越大,转化的真空阻力也越大,本发明无需额外增加卡箍,节省了实物成本和卡箍安装成本。
