Description
一种氯气专用阀
技术领域
[0001 ] 本实用新型涉及一种阀门，具体的说是一种用于化工行业氯气管道上控制介质流 动的氯气专用阀。
背景技术
[0002] 目前，我国化工行业没有专供氯气用截止阀，氯气管道上均使用普通截止阀，由于 密封联接形式和结构不尽合理，密封件和材料不耐腐蚀，易脱落损坏，易泄漏，甚至发生安 全事故，阀门使用寿命短，更换频繁，影响生产，造成经济损失。
实用新型内容
[0003] 本实用新型的目的在于提供一种密封结构新颖，密封性能好，安全可靠，使用寿命 长的氯气专用阀。
[0004] 本实用新型包括阀盖、阀体、阀座、阀瓣、阀杆、手轮，所述阀盖连接在阀体上，在阀 体内腔设置阀座，于阀座上布置阀瓣，所述阀瓣通过阀杆与手轮连接，所述阀杆的中部螺纹 连接在阀盖上，所述阀座设有断面呈燕尾形的环形槽，所述环形槽的槽口宽度小于槽底宽 度，在所述环形槽内固定连接密封件，所述阀瓣与阀座配合的端面为锥平面，在所述锥平面 的外表面固定设置耐腐硬质合金层。
[0005] 本实用新型与现有技术相比具有如下优点：
[0006] 1、该阀座表面置有槽口宽度小于槽底宽度的燕尾形环形槽，且在环形槽内固定设 置密封件，密封件在环形槽内固定牢固，不易错位脱落，密封性能好，安全可靠。
[0007] 2、阀瓣表面置有硬质合金层，采将硬质合金层与阀瓣基体烧结为一体，使阀瓣耐 摩擦性能好，使用寿命长。
[0008] 3、阀瓣端部的锥平面设计，在阀门关闭时具有较好的导向性，可减少密封面冲击， 减少流阻，与现有技术相比，具有密封性能可靠，无泄漏，维修方便，操作省力，使用寿命长 等优点。
[0009] 本实用新型的所述锥平面的锥角为60°，可达到更好的密封效果。
[0010] 另，本实用新型还在所述阀盖与阀体之间以相互配合的槽连接，在所述槽内设置 弹性密封垫。
[0011] 使阀盖与阀体两者连接的密封性更好。
[0012] 附图说明
[0013] 图1是本实用新型氯气专用阀的结构示意图。
[0014] 具体实施方式
[0015] 如图1所示，本实用新型主要由阀体1、阀座2、阀瓣3、阀盖4、阀杆5、压盖6、手轮 7组成。
[0016] 阀盖4通过螺栓连接在阀体1上，阀盖4与阀体1之间以相互配合的槽连接，在该 槽内设置弹性密封垫41。[0017] 在阀体1内腔设置阀座2，于阀座2上布置阀瓣3，阀瓣3通过阀杆5与手轮7连 接，阀杆5的中部螺纹连接在阀盖4上。阀座2设有断面呈燕尾形的环形槽21，环形槽21 的槽口宽度小于槽底宽度，在环形槽21内整体烧结聚四氟乙烯密封件22。阀瓣3与阀座2 的密封件22配合的端面为锥平面，在该锥平面的外表面固定设置耐腐硬质合金层31，其锥 角可为60°，上述耐腐硬质合金层31与阀瓣3基体烧结为一体。
[0018] 使用时，逆时针旋转手轮7，带动阀杆6、阀瓣3向上运动，阀门开启，介质经阀座2 通过阀体1。
