Description

一种抗压能力强的螺纹盖板
技术领域:
本实用新型主要涉及滤清器技术领域,尤其涉及一种抗压能力强的螺纹盖板。 
背景技术:
发动机有空气、机油、燃油三种滤清器,一般称作“三滤”。它们分别担负发动机进气系统、润滑系统和燃烧系统中介质的过滤。目前,全流式滤清器得到广泛使用,其重要部件为滤芯,设于外壳、螺纹盖板、密封盖板、密封圈和安装底座等构件组成的密闭空间内,这要求他们具有良好的密封性能。 
为保证良好的密封性能,必须保证密封盖板的抗压能力。已有技术中提高密封盖板的抗压能力是通过增加密封盖板的厚度,但是,这种方法会提高生产成本。 
实用新型内容:
本实用新型目的就是为了弥补已有技术的缺陷,提供一种结构设计合理的滤清器的螺纹盖板。 
本实用新型是通过以下技术方案实现的: 
一种抗压能力强的螺纹盖板,包括有环形的盖板体,盖板体中心设有背向滤清器安装底座延伸的螺纹中心孔,其特征在于:所述盖板体的环形外沿部位为平直的平展部,平展部和螺纹中心孔上部之间设有倾斜的过渡部,所述过渡部上分布有过滤孔;所述盖板体的上表面设有抗压层。 
所述的一种抗压能力强的螺纹盖板,其特征在于:所述波纹盖板为热轧酸洗板。 
所述的一种抗压能力强的螺纹盖板,其特征在于:所述过滤孔的截面为D形。 
本实用新型的优点是: 
本实用新型结构简单,设计合理,通过平展部和过渡部的合理设计,以及抗压层的添加,提高了螺纹盖板的抗压能力,保证了良好的密封性能,满足了企业的使用需求。 
附图说明:
图1、2为本实用新型的结构示意图。 
具体实施方式:
参见附图。 
一种抗压能力强的螺纹盖板,包括有环形的盖板体1,盖板体1中心设有背向滤清器安装底座延伸的螺纹中心孔2,所述盖板体1的环形外沿部位为平直的平展部3,平展部3和螺纹中心孔2上部之间设有倾斜的过渡部4,所述过渡部4上分布有过滤孔5。所述盖板体1的上表面设有抗压层6。 
过滤孔5的截面为D形。
