Abstract

本发明公开了一种耐腐蚀快关阀，包括阀体、阀盖、阀瓣、阀杆及设在阀盖支架上的手、气动操作机构；阀瓣底部端面与阀体接触面处设有异形槽，异形槽内填充有弹性耐腐材料层；阀瓣上装有圆柱压缩弹簧；弹性耐腐材料层高出异形槽，使得阀瓣与阀体之间形成软密封；阀盖与阀杆结合的通孔中设有两只大小不同的弹性密封圈，形成第二重软密封；阀体内腔设有耐腐蚀涂层。本发明耐腐蚀，使用寿命长。

Description

耐腐蚀快关阀
技术领域
本发明涉及一种快关阀，特别涉及一种采用软密封的快关阀。
背景技术
现有快关阀包括阀体、阀盖、阀瓣、阀杆及设在阀盖支架上的手、气动操作机构，这种快关阀的缺陷在于：在腐蚀性介质中容易腐蚀。
发明内容
本发明针对现有技术的不足，提供一种能显著提高耐腐蚀性的耐腐蚀快关阀。
本发明通过下述技术方案实现技术目标。
耐腐蚀快关阀，包括阀体、阀盖、阀瓣、阀杆及设在阀盖支架上的手、气动操作机构；所述阀瓣底部端面与阀体接触面处设有异形槽，异形槽内填充有弹性耐腐材料层；所述阀瓣上装有圆柱压缩弹簧；所述弹性耐腐材料层高出异形槽，使得阀瓣与阀体之间形成软密封；所述阀盖与阀杆结合的通孔中设有两只大小不同的弹性密封圈，形成第二重软密封；其改进之处在于：所述阀体内腔设有耐腐蚀涂层。
本发明与现有技术相比，具有以下积极效果：阀体内腔设有耐腐蚀涂层，显著提高本发明的耐腐蚀性，延长使用寿命。
附图说明
图1为本发明结构示意图。
具体实施方式
下面根据附图并结合实施例对本发明作进一步说明。
如图所示的耐腐蚀快关阀，包括阀体1、阀盖2、阀瓣3、阀杆4及设在阀盖2支架上的手、气动操作机构5；阀瓣3底部端面与阀体1接触面处设有异形槽6，异形槽6内填充有弹性耐腐材料层7；阀瓣3上装有圆柱压缩弹簧；弹性耐腐材料层7高出异形槽6，使得阀瓣3与阀体1之间形成软密封；阀盖2与阀杆4结合的通孔中设有两只大小不同的弹性密封圈7，形成第二重软密封；阀体1内腔设有耐腐蚀涂层。
