Description

一种调节式蝶阀
技术领域
本实用新型涉及一种阀门装置,特别是涉及一种蝶阀。
背景技术
目前使用在冶金行业的调节阀,传统采用蝶阀结构,由于阀门前后压差大,气体在流经阀板时,特别是当蝶板处于小开度时,气流产生剧烈扰动,产生震动、噪声,对阀体内壁由于冲刷,磨损严重,使用寿命短。
发明内容
为了克服现有调节阀震动严重、噪音大、阀门磨损严重,使用寿命短的不足,本实用新型提供一种噪音小使用寿命长的调节式蝶阀。
本实用新型解决其技术问题所采用的技术方案是一种调节式蝶阀,包括阀体、阀杆、填料、填料压盖、轴承,阀杆与阀体之间通过填料及填料压盖密封,阀杆与阀体接触处装有轴承阀体内装有定蝶板,阀杆下部装有动蝶板,定蝶板与动蝶板上开有长条形槽,阀体内腔与动蝶板对应处开有槽。阀杆上端开有螺旋槽。
本实用新型的有益效果是不会产生扰动,流量特性好,使用寿命长。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1实施例的剖视图。
图2是定蝶板构造图。
图3是动蝶板构造图。
图中:1.螺旋槽;2.阀杆;3.填料压盖;4.填料;5.轴承;6.阀体;7.动蝶板;8.定蝶板。
具体实施方式
如图1所示,一种调节式蝶阀,包括阀体6、阀杆2、填料4、填料压盖3、轴承5,阀杆2与阀体6之间通过填料4及填料压盖3密封,阀杆2与阀体6接触处装有轴承5,阀体6内装有定蝶板8,阀杆2下部装有动蝶板7,定蝶板8与动蝶板7上开有长条形槽9,在全开位置时,定蝶板8与动蝶板7的长条形槽9正好一致,介质呈直线流动,不产生扰动、旋涡;在全关位置时,定蝶板8与动蝶板7上的长条形槽9位置错开,阀门密封。阀杆2上端开有螺旋槽1,可以采用同一驱动装置,便于替代。
