【技术实现步骤摘要】
自润滑压紧式液体灌装阀
本技术涉及管状设备,具体涉及自润滑压紧式液体灌装阀。
技术介绍
现有技术中的灌装阀多采用气缸来带动阀芯运动实现对液体的抽取,传统的灌装阀为了确保密封性能,结构比较复杂,不但拆卸麻烦。而且,需要润滑油等机构和油脂对气缸活动的推杆部件进行润滑作用。随着时间的增加,润滑的油脂会随着缝隙进入灌装阀腔内,容易污染灌装液体。因此,传统结构的灌装阀需要经常进行维护拆卸,严重影响了设备的生产效率。
技术实现思路
为了解决现有技术的不足,本技术提供了自润滑压紧式液体灌装阀。本技术的技术方案是:自润滑压紧式液体灌装阀,包括阀体,设置于阀体内的阀芯,与所述阀体连接的气缸,所述气缸推杆通过连接杆与阀芯连接,所述气缸通过连接柱连接有密封连接件,所述密封连接件的另一端连接阀体,所述密封连接件包括壳体,设置与壳体的密封挡件,所述密封挡件为底部带有限位凸起的筒状结构,所述密封挡件内设置有特氟龙密封环,所述特氟龙密封环下端面与限位凸起接触,上端面设置压紧螺栓。本技术的进一步改进包括:所述阀体与密封连接件通过快速卡紧装置连接。本技术结构简单,通过连接柱实现了气路、液路的分离,通过快速卡紧装置实现各部分的快速拆卸,通过压紧螺栓和特氟龙密封环实现阀体上的密封和润滑问题。通过气缸,连接杆,阀芯完成灌装阀的开启、关闭功能。本技术结构简单,避免使用润滑油脂污染灌装液体,减少密封材料的使用和更换维护工作。附图说明图1是本技术的结构示意图。图中:1、阀体,2、阀芯,3、连接杆,4、气缸,5、连接柱,6、气缸推杆,7、壳体,8、密封挡件,9、特氟龙密封环。10、压紧螺栓。具体实施方式下面 ...
