Abstract

一种法兰联结式方型双侧开浮箱拍门阀,它属于一种法兰联结式方型双侧开浮箱拍门阀。它主要是解决现有的阀门开启角度小,水头损失大和难以完全密封等技术问题。其技术方案要点是:它采用水封,在阀体左、右两侧设有调节板(5),调节板(5)与旋臂(8)连接密封,浮箱门(3)设于旋臂(8)上且位于P型水封(2)下方,避免介质泄漏;根据力学原理,将铰耳(6)和半圆头轴销(7)竖向布置,并向里倾斜3°,浮箱门利用自重的水平分力作动力,达到开启角度大,水头损失小,既能够自动关闭,又能够完全密封的目的。它主要是用于排灌泵站断流。

Description

法兰联结式方型双侧开浮箱拍门阀
技术领域
本实用新型涉及一种排灌设备,特别是一种法兰联结式方型双侧开浮箱拍门阀。
背景技术
目前,在国内、外排灌泵站中,使用的水阀普遍是一种悬启式止回阀,这种悬启式止回阀,存在阀门开启角度小,水头损失大和难以完全密封等缺陷。到目前为止,在市场上还尚未见到一种阀门开启角度大,水头损失小,既能够自动关闭,又能够完全密封的法兰联结式方型双侧开浮箱拍门阀。
湖南省邵阳市液压件厂宿舍22栋408号的张坚于2009年1月20日申请2009年11月4日公开的200920062984.0 “节能型预埋式双侧开浮箱拍门阀”,包括阀体、橡胶圈、拍门、直梁、后法兰和铰链,其特征在于:在阀体前端设有橡胶圈,在橡胶圈前面设有拍门,在阀体中部设有直梁,在阀体尾端设有后法兰,在阀体前端两边设有铰链,拍门安装在铰链上。将拍门做成双侧开浮箱式,将阀体做成长筒形并在尾端带有预埋式后法兰,将阀体前端两边的铰链和拍门竖向布置并分别向直梁中心倾斜1-25°。该成果没有确定阀体最佳旋转角度,橡胶圈的密封性能不强且使用寿命短;本实用新型将铰耳和半圆头轴销竖向布置,并向里倾斜3°,且使用水封,在阀体1两侧设有调节板5,调节板5能够调节浮箱门3与阀体1之间的密封缝隙,避免介质泄漏,使效果更好。
发明内容
本实用新型的目的是提供一种的法兰联结式方型双侧开浮箱拍门阀。
本实用新型解决其技术问题所采用的技术方案是:它包括阀体1、P型水封2、浮箱门3、U型水封4、调节板5、铰耳6、半圆头轴销7和旋臂8,在阀体1下方两端设有P型水封2,在阀体1两侧设有调节板5,调节板5通过铰耳6与旋臂8连接,铰耳6中设有半圆头轴销7,两个浮箱门3位于P型水封2下方且分别设置在两侧的旋臂8上,在右侧浮箱门3顶端设置有U型水封4。
本实用新型所述阀体1为矩形。
本实用新型还可在阀体1中间设置横杆,将浮箱门3做成两侧浮箱式。
本实用新型所述铰耳6和半圆头轴销7竖向布置,并向内倾斜3°。
本实用新型的有益效果是:开启角度大,水头损失小,既能够自动关闭,又能够完全密封。

具体实施方式
下面结合附图和实施例对本实用新型做进一步详细说明。
实施例1,本实用新型是一种法兰联结式方型双侧开浮箱拍门阀,它包括阀体1、P型水封2、浮箱门3、U型水封4、调节板5、铰耳6、半圆头轴销7、旋臂8,在阀体1下方两端设有P型水封2,在阀体1两侧设有调节板5,调节板5通过铰耳6与旋臂8连接,铰耳6中设有半圆头轴销7,两个浮箱门3位于P型水封2下方且分别设置在两侧的旋臂8上,在右侧浮箱门3顶端设置有U型水封4。参阅图1至图3。
实施例2,本实用新型将阀体1做成方形。参阅图1至图3,其余同实施例1。
实施例3,阀体1中间设置横杆,将浮箱门3做成两侧浮箱式。参阅图1至3,其余同上述实施例。
实施例4,本实用新型根据力学原理,将铰耳6和半圆头轴销7竖向布置,并向里倾斜3°,浮箱门3利用自重的水平分力作动力,达到开启角度大,水头损失小,既能够自动关闭,又能够完全密封的目的。参阅图1至3,其余同上述实施例。
实施例5,本实用新型采用水封,在阀体1左右两侧设有调节板5,调节板5能够调节浮箱门3与阀体1之间的密封缝隙,避免介质泄漏。参阅图1至图3,其余同实施例1。
实施例6,本实用新型所述铰链包括铰耳、销轴和垫片,铰耳中设有销轴,销轴一端设置成半圆头形,半圆头端上面设置有垫片;也可在铰耳与销轴之间设置有衬套。它通过将轴销一端设置成半圆头形,根据力学原理,将半圆头端设置在受力端,可起支撑作用,设置成倾斜一定角度的情况时,可减少摩擦力,使浮箱门依靠自身重力的水平分力达到关闭与开启的目的。它主要是用于开浮箱拍门阀的浮箱门连接。参阅图1至3,其余同上述实施例。
