Abstract
一种陶瓷阀杆,属于机械零件,它的结构是阀杆体外表面涂覆陶瓷层,或阀杆体外套装陶瓷管。本实用新型的有益效果是:涂覆或套装陶瓷层或管的阀杆,耐磨损,耐腐蚀,延长使用寿命,减少更换频率,降低生产成本。
Description
技术领域
本实用新型属于一种机械零件,特别涉及一种陶瓷阀杆。
背景技术
现有技术中的阀门的阀杆,通常情况下采用碳钢、不锈钢材料,在高腐蚀的情况下,会采用哈氏合金、双相不锈钢材料制成,在含有固体颗粒的介质中,阀杆启闭过程中,易夹入固体颗粒,划伤阀杆,造成泄露和阀门失效。而在含有氯离子、硫酸根离子、或硫化氢等酸性介质的情况下,哈氏合金、双相不锈钢材料成本很高,也仅仅是比普通不锈钢材料的阀杆使用寿命长一些,不能根本解决上述问题。
实用新型的内容
本实用新型的目的在于克服上述的缺陷,提供一种陶瓷阀杆,它耐磨损、耐腐蚀、延长使用寿命,减少了更换次数,降低了生产成本。
本实用新型的目的是通过以下技术方案实现的:一种陶瓷阀杆,它包括阀杆体,其特征在于:所说的阀杆体外表面涂覆陶瓷层。
一种陶瓷阀杆,它包括阀杆体,其特征在于:所说的阀杆体外套装陶瓷管。
所说的陶瓷层或陶瓷管是氧化物陶瓷层/管,或碳化物陶瓷层/管,或氮化物陶瓷层/管。
本实用新型的有益效果是:使用陶瓷层制作的阀杆,耐磨损,耐腐蚀,延长使用寿命,减少更换频率,降低生产成本。
附图说明
图1是本实用新型实施例一结构示意图。
图2是本实用新型实施例二结构示意图。
具体实施方式
实施例1:如图所示,一种陶瓷阀杆,它包括阀杆体1,在阀杆体1外表面涂覆陶瓷层2。
实施例2:一种陶瓷阀杆,它包括阀杆体1,在阀杆体1外套装陶瓷管2。
实施例1和实施例2所说的陶瓷层或陶瓷管是氧化物陶瓷层/管,或碳化物陶瓷层/管,或氮化物陶瓷层/管。
Claims (3)
1.一种陶瓷阀杆,它包括阀杆体,其特征在于:所说的阀杆体外表面涂覆陶瓷层。
2.一种陶瓷阀杆,它包括阀杆体,其特征在于:所说的阀杆体外套装陶瓷管。
3.如权利要求1或2所说的一种陶瓷阀杆,其特征在于:所说的陶瓷层或陶瓷管是氧化物陶瓷层/管,或碳化物陶瓷层/管,或氮化物陶瓷层/管。
