摘要
目的为了提高灌装设备的灌装精度,解决灌装过程中的喷溅问题。方法根据现有上开阀式灌装阀的结构特点,创新设计一种中心小流量上开阀式灌装阀。该灌装阀通过活塞头的下锥面与活塞密封板形成锥面密封,构成柱塞高位的内密封结构,且在活塞头上设计由横向导流孔和中心导流孔所构成的小流量通道。结果该灌装阀小流量流速稳定,灌装精度易于控制,工作时无喷溅现象,不仅适用于普通液体物料的包装,也可用于粘度大的膏状物料的灌装设备。结论经大量实践证明,该灌装阀具有结构合理、可靠性高、适用范围广等优点,并具有良好的推广价值和经济效益。
The work aims to improve the filling precision of the filling equipment and solve the splashing problem in the filling process. According to the structural features of existing valve, a central-small-flow filling valve was creatively designed which was opened with the valve stem moving up. In the filling valve, a cone sealing was formed between the lower conical surface of piston head and the piston sealing plate, thus leading to an inner sealing structure at high position of the plunger plug. The small-flow channel composed of transverse diversion hole and the central diversion hole was de- signed on the piston head. The filling valve was at a stable small flow velocity, the filling precision was easily controlled and no splashing phenomenon occurred during working, which was not only suitable for the packaging of ordinary liquid materials, but also could be used in the filling equipment for paste material with high viscosity. A large number of prac- tices show that the filling valve is featured by many advantages, such as reasonable structure, high reliability and wide application range, and it has good promotional values and economic benefits.
