The invention relates to a sealing ring for a filter bag of a liquid filter. It is characterized in that the sealing ring is made of a grade two level bending, bending and bending a body out of the skirt; the upper end of a bent sealing surface with the level of a certain angle, the bending rim and the upper end extends out of the sealing surface of a certain angle, the lower ends of the sealing skirt a certain angle with the horizontal plane. The invention provides a sealing ring at the upper end of the lower cover skirt and bending close sealing surface respectively with liquid filter cover or cover, a filter chamber port combination of linear combination, the formation mechanism of high performance sealing, no leakage. In the outer edge of the two stage bending body, a plurality of flanges along the circumferential direction are fused with the filter bag into a whole, the strength is large, the impact force can be affected, and the replacement of the filter bag or the cleaning of the filter bag is also very convenient. The invention has the advantages of reasonable structural design and low production cost, and the filtration efficiency is improved by 5% because of improving the sealing property, and the cycle filtration is effectively avoided, not only the energy is saved, but also the good economic benefit is obtained.
【技术实现步骤摘要】
本专利技术涉及一种过滤分离技术,更具体地说涉及一种液体过滤器滤袋用密 封圈。
技术介绍
在现有技术中,随着国民经济的迅猛发展及人民生活水准的提高,人们对 物品品质的要求也越来越高,其中对过滤、分离技术的应用、要求也越来越多, 该技术目前普遍存在的问题是液体过滤器滤袋与过滤器上盖及过滤腔室端口 的密封不良,经常发生泄漏,导致过滤精度差、效率不高,常有发生待滤的上 游滤液直接渗漏到下游,需循环过滤,造成过滤效率和产品质量的下降;同时 还存在密封圈与过滤袋结合差,易脱落、更换不便等缺陷。
技术实现思路
本专利技术的目的是针对现有技术不足之处而提供一种在液体过滤器滤袋与过 滤器上盖及过滤腔室结合部位形成高性能的密封机制、能承受过滤压力变化的、 适应性强的液体过滤器滤袋用密封圈。本专利技术的目的是通过以下措施来实现 一种液体过滤器滤袋用密封圈,其 特殊之处是密封圈由一级折弯、二级折弯的本体和一级折弯处伸出的裙边所 组成;所述一级折弯的上端密封面与水平成一定的角度,其折弯处伸出的裙边 与上端密封面有一定的夹角,所述裙边的下端密封面与水平成一定的角度。所述一级折弯的上端密封面与水 ...
