Abstract

本实用新型有关一种不锈钢闸阀,闸阀阀腔的内表面设置陶瓷层,它是采用等离子陶瓷粉末热喷涂方法,可广泛用于炼油系统储化装置,烈化装置及管网工种中普通材料,可提高闸阀的使用寿命。

Description

不锈钢闸阀
本实用新型涉及一种不锈钢闸阀。
目前的不锈钢闸阀,在长期使用后,由于化学流体的作用,其内腔表面易磨损、腐蚀,且不耐高温,影响了使用寿命,需经常更换。
本实用新型的目的在于克服现有技术的缺陷,提供一种耐磨损、耐腐蚀、抗高温、使用寿命长的不锈钢闸阀。
本实用新型的不锈钢闸阀阀腔的内表面设置陶瓷层。
以下是本实用新型的实施例和附图。
附图为本实施例的结构示意图。
本不锈钢闸阀的阀腔1的内表面均匀设置陶瓷层2,特别适用在高温条件下使用,它是利用等离喷涂工艺对机构另件表面进行加工,采用等离子弧将各种合金金属、工程陶瓷、刚玉陶瓷等各种粉末,迅速加热熔化、雾化,并以2倍的音速、高速喷射到经净化处理的内外工作表面而成。
本实用新型由于在不锈钢闸阀内腔表面设置了陶瓷层,从而形成耐磨损、耐腐蚀、抗高温氧化、导电绝缘、远红外辐射、摩擦系数稳定表面光滑等优异性能的工作深层,提高了产品的使用寿命。
