Description

一种耐磨阀门喷涂工艺
技术领域
本发明涉及一种阀门，尤其是一种耐磨阀门喷涂工艺。
背景技术
高炉渣是在高炉冶炼生产过程中，由矿石中的脉石、燃料中的灰粉和溶剂 (一般是石灰石)中的非挥发组分形成的固体废物。在将高炉水渣中的水与渣分离过程中，其管线中的水泵进出口及总管需要用到阀门来进行有效切断介质。目前使用的蝶阀，大多数不进行耐磨处理或只在表面喷涂一层硬质合金，造成阀体三、四道轴座及阀轴极易磨损，易泄漏。
发明内容
为了解决现有技术不足，本发明提供一种耐磨阀门喷涂工艺。
本发明的技术方案是，一种耐磨阀门喷涂工艺，喷涂工艺步骤如下：
步骤1：对阀体三道轴座、四道轴座进行倒圆角加工处理，然后将阀体、密封圈及压圈组装完成后对密封圈密封面进行保护，接着对阀体内通道以及三道轴座和四道轴座轴孔内部喷涂碳化钨，喷涂厚度0.3～0.5mm。
步骤2：对加工完的阀板密封面及轴孔进行保护，然后对阀板表面喷涂碳化钨，喷涂厚度0.3～0.5mm。
步骤3：对阀轴与介质接触部位进行加工，加工完成后对加工处喷涂碳化钨，喷涂厚度0.3mm，再对喷涂部位进行自动研磨。
优选地，步骤1至步骤3中喷涂碳化钨采用超音速火焰喷涂。
优选地，步骤3中研磨后的表面粗糙度为Ra0.8。
本发明的有益效果是，通过对阀体、阀板及阀轴上所有与介质接触表面喷涂碳化钨，提高阀门内部整体耐磨性能，提高了使用寿命。

具体实施方式
如图所示，一种耐磨阀门喷涂工艺，工艺步骤如下：
步骤1：对阀体三道轴座1、四道轴座2进行倒圆角加工处理，然后将阀体、密封圈及压圈组装完成后对密封圈密封面进行保护，接着对阀体内通道4以及三道轴座1和四道轴座轴2孔内部采用超音速火焰喷涂碳化钨，喷涂厚度0.3～ 0.5mm；步骤2：对加工完的阀板密封面5及轴孔6进行保护，然后对阀板表面采用超音速火焰喷涂碳化钨，喷涂厚度0.3～0.5mm；步骤3：对阀轴与介质接触部位进行加工，加工完成后对加工处喷涂碳化钨，喷涂厚度0.3mm，再对喷涂部位进行自动研磨，研磨后的表面粗糙度为Ra0.8。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
