【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。
[Abstract]:Objective to improve the filling accuracy of filling equipment and solve the problem of spatter during filling. Methods according to the structural characteristics of the existing upper-opening valve filling valve, a new type of filling valve with center and small flow rate was designed. The filling valve forms a cone seal with the piston seal plate through the lower cone of the piston head, which forms the internal seal structure of the plunger high position, and designs a small flow channel on the piston head consisting of a transverse diversion hole and a central diversion hole. Results the filling valve has the advantages of stable flow rate, easy control of filling precision and no spatter, which is not only suitable for packing of ordinary liquid materials, but also for filling equipment of paste materials with high viscosity. Conclusion it is proved by a large number of practice that the filling valve has the advantages of reasonable structure, high reliability and wide application range, and has good popularization value and economic benefit.
