The invention discloses a non-return valve plate, including the main valve plate, the main valve plate are mounted at the top end of the shaft, the valve plate is provided with a main body side reinforcement bar, wherein the main reinforcement bar and the rotation axis is set, the main reinforcing rods are arranged at both sides of the auxiliary reinforcement, the auxiliary reinforcement a rotating shaft is arranged in parallel with and adjacent auxiliary reinforcement arc reinforcing strips shall be set between the main valve plate in the main reinforcing rod is arranged at the side edge of the card slot, the rubber pad is arranged on the card slot, the main valve plate away from the groove surface is provided with ceramic wear layer, the wear resistance of ceramic the layer is arranged on the outer side of the rubber layer. By setting the main reinforcement bar and auxiliary reinforcement bar in the valve plate, enhance the mechanical performance of the valve plate, the valve plate and its reduced thickness, solve the disadvantages of the traditional valve plate is bulky, the auxiliary reinforcement thickness from the inside to the outside gradually reduced, do the rational use of materials, not to waste.
【技术实现步骤摘要】
一种止回阀板
本专利技术涉及止回阀
,具体为一种止回阀板。
技术介绍
止回阀是指依靠介质本身流动而自动开、闭阀瓣,用来防止介质倒流的阀门,又称逆止阀、单向阀、逆流阀、和背压阀。止回阀属于一种自动阀门,其主要作用是防止介质倒流、防止泵及驱动电动机反转,以及容器介质的泄放。目前,用于防止水倒流的止回阀板较为笨重、造价高,而且密封质量也不稳定。
技术实现思路
本专利技术的目的在于提供一种止回阀板,以解决上述
技术介绍
中提出的问题。为实现上述目的,本专利技术提供如下技术方案:一种止回阀板,包括阀板主体,所述阀板主体顶端安装有转轴,所述阀板主体一面设置有主加固杆,所述主加固杆与转轴垂直设置,所述主加固杆两侧设置有辅助加固条,所述辅助加固条与转轴平行设置,相邻辅助加固条之间设置有弧形加固条,所述阀板主体位于主加固杆一面的边缘处设置有卡槽,所述卡槽上设置有橡胶垫,所述阀板主体远离卡槽一面设置有陶瓷耐磨层,所述陶瓷耐磨层外侧设置有橡胶层。优选的,所述阀板主体设置为对称结构。优选的,所述辅助加固条厚度由内到外逐渐缩小。优选的,所述橡胶层内部设置有陶瓷耐磨颗粒。与现有技术相比,本专利技术的有益效果是:本专利技术通过在阀板一侧设置主加固杆和辅助加固条,增强了阀板的受力性能,从而可减小阀板自身的厚度,解决传统阀板笨重的弊端,将辅助加固条厚度由内到外逐渐缩小,做到合理利用材料,不浪费;通过在阀板主体外侧边缘设置橡胶垫,增强了阀板的密封性能;通过设置陶瓷耐磨层和橡胶层,增强了阀板的耐磨性能。附图说明图1为本专利技术的结构示意图。图2为本专利技术A-A处的剖视图。图3为本专利技术板体的 ...
