Description

压缩机气阀
技术领域
本发明涉及压缩机制造技术领域,尤其是一种用于氯乙烯气体压缩机的气阀。
背景技术
在氯乙烯化工行业中要用到氯乙烯气体压缩机,氯乙烯压缩机就是压缩氯乙烯气体借以提高氯乙烯气体压力的压缩机,氯乙烯气体是一种易燃、易爆、腐蚀性很强的气体;因此,经常运行的氯乙烯压缩机,易损件需经常更换,尤其是气阀;目前,市面上氯乙烯压缩机气阀的阀片大多由不锈钢制成,不锈钢件的阀片在反复的闭合、打开中被氯乙烯气体腐蚀,使阀片的使用寿命短,更换频率高,增加气阀的使用成本。
发明内容
本发明提供一种压缩机气阀,它可以解决现有压缩机气阀的使用寿命短、更换频率高的问题。
为了解决上述问题,本发明所采用的技术方案是:具有有阀座,该阀座上装有阀盖,在所述阀座和所述阀盖之间设有阀片,在所述阀片与所述阀盖之间通过压缩弹簧连接,所述阀片为复合阀片,该阀片上层为橡胶层,下层为聚氯乙烯层。
的阀片,具有良好的化学稳定性,耐腐蚀性,硬度大,强度大,强度高,耐火阻燃,具有自熄性,绝缘性能可靠,表面光洁平整,不吸水,不变形;
由于采用了上述技术方案,本发明与现有技术相比具有如下有益效果:
由于本发明的阀片聚氯乙烯层复合橡胶层制成,聚氯乙烯层具有良好的化学稳定性、耐腐蚀性、硬度大、强度高、耐火阻燃、具有自熄性、不易变形;从而使用寿命长,不用经常更换,从而减少了气阀的使用成本。
附图说明
图1是本发明的结构示意图。
具体实施方式
以下结合附图实施例对本发明作进一步详述:
如图1所示的实施例,它具有有阀座1,该阀座上装有阀盖2,在阀座1和阀盖2之间设有阀片,在阀片与阀盖2之间装有多个压缩弹簧3,连接,阀片为复合阀片,该阀片上层为橡胶层4-1,下层为聚氯乙烯层4-2,聚氯乙烯层与阀座接触,压缩机运行时,阀片在反复的闭合、打开中由聚氯乙烯层与氯乙烯接触,由于聚氯乙烯层具有良好的化学稳定性、耐腐蚀性、硬度大、强度高、耐火阻燃、具有自熄性、不易变形,从而使用寿命长,不用经常更换,从而减少了气阀的使用成本。
