Abstract

本实用新型公开了软密封蝶阀,包括有筒形的阀体、阀座,阀体内横置有盘形的阀芯,阀芯的上端、下端与阀座之间穿过有上半轴、下半轴,阀体两端分别为进水口、出水口,进水口内壁上固定设有与阀芯相对应的密封圈,密封圈外侧压置有压套,上半轴与阀座之间设有密封套。本实用新型具有耐高温,密封性强,操作轻便,启闭无磨擦,关闭时随着传动机构的力矩增大来补偿密封,提高了蝶阀的密封性能及延长使用寿命的优点。

Description

软密封蝶阀
技术领域
    本实用新型涉及软密封蝶阀。
背景技术
软密封蝶阀的蝶板安装于管道的直径方向。在蝶阀阀体圆柱形通道内,圆盘形蝶板绕着轴线旋转,旋转角度为0°~90°之间,旋转到90°时,阀门则牌全开状态。
目前 ,软密封蝶阀作为一种用来实现管路系统通断及流量控制的部件,已在石油、化工、冶金、水电等许多领域中得到极为广泛地应用。在已公知的蝶阀技术中,其密封形式多采用密封结构,密封材料为橡胶、聚四氟乙烯等。由于结构特征的限制,不适应耐高温、高压及耐腐蚀、抗磨损等行业。
实用新型内容
    本实用新型的目的是提供一种软密封蝶阀,具有耐高温,密封性强,操作轻便,启闭无磨擦,关闭时随着传动机构的力矩增大来补偿密封,提高了蝶阀的密封性能及延长使用寿命的优点。
软密封蝶阀,包括有筒形的阀体、阀座,阀体内横置有盘形的阀芯,阀芯的上端、下端与阀座之间穿过有上半轴、下半轴,阀体两端分别为进水口、出水口,进水口内壁上固定设有与阀芯相对应的密封圈,密封圈外侧压置有压套,上半轴与阀座之间设有密封套。
所述的密封套内开有密封槽,密封槽内设有O形密封圈。
本实用新型具有耐高温,密封性强,操作轻便,启闭无磨擦,关闭时随着传动机构的力矩增大来补偿密封,提高了蝶阀的密封性能及延长使用寿命的优点。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,软密封蝶阀,包括有筒形的阀体1、阀座2,阀体1内横置有盘形的阀芯3,阀芯3的上端、下端与阀座之间穿过有上半轴4、下半轴5,阀体1两端分别为进水口、出水口,进水口内壁上固定设有与阀芯相对应的密封圈6,密封圈6外侧压置有压套7,上半轴4与阀座2之间设有密封套8,密封套8内开有密封槽,密封槽内设有O形密封圈。
