高分子材料增强的止回阀
本技术涉及阀门
,具体涉及一种止回阀。
技术介绍
止回阀又称单向阀或逆止阀,其作用是防止管路中的介质定向流动而不致倒流的功能。止回阀是一种常用的阀类装置,其原理是依靠介质流动的力量实现启闭,以防止介质的倒流。止回阀主要用于介质单向流动的管道上,只允许介质向一个方向流动。当水流猛烈撞击阀芯,带动阀芯触碰到阀体内壁,阀体内壁很容易受到损伤甚至破裂;当水流停止时,阀芯受重力作用突然闭合在阀体上,阀体容易受到损坏,进而影响到止回阀的使用寿命大大缩短,因此有必要对止回阀进行改造,延长止回阀的使用寿命。
技术实现思路
本技术的目的在于,提供高分子材料增强的止回阀,以解决上述技术问题。本技术所解决的技术问题可以采用以下技术方案来实现:高分子材料增强的止回阀,包括阀体和阀芯,所述阀体是钢制阀体,所述阀芯是钢制阀芯,其特征在于:所述阀体的内腔附着一纳米陶瓷层;所述阀芯外壁附着一纳米陶瓷层,所述纳米陶瓷层外还附着一玄武岩纤维层;所述纳米陶瓷层中设有均匀排布的凸起,所述凸起形成阵列,且所述凸起嵌入到所述玄武岩纤维层中;所述凸起的高度为0.1mm-0.2mm;所述纳米陶瓷层的厚度为0.3mm-0.5mm;所述玄武岩纤维层的厚度为0.3mm-0.4mm。本专利中阀体和阀芯均采用纳米陶瓷涂层,纳米陶瓷具有耐腐蚀、耐高温,耐磨性强,启闭灵活的特点,能够消除疲劳强度,延长使用寿命。流体经过阀体,不容易粘附在上面。同时阀芯外壁还附着一玄武岩纤维层,具有柔性和耐磨性,解决了阀芯与阀体进行碰撞,从而造成损坏。同时纳米陶瓷层中设有凸起,使纳米陶瓷层与玄武岩纤维层之间的连接更 ...
