Abstract

本实用新型涉及一种抗冲刷闸板阀,包含阀体、阀杆、闸板架,阀体内有一内腔,闸板架处在阀体内腔中,阀杆穿过阀体上半部且下端与闸板架连接,闸板架的下端加连有一锥形导流孔,导流孔位于阀体流道进料侧一端的孔径与进料侧尺寸相同,另一端的外壁紧贴出料侧的内壁。使用上述装置的闸板阀,介质流过时不会碰触出料侧的密封面,从而达到了防止介质对出料侧密封面进行冲刷的效果。

Description

一种抗冲刷闸板阀
技术领域
 本实用新型涉及一种抗冲刷闸板阀。
背景技术
目前使用的闸板阀,其进出口的管道都是相同大小,当阀门打开时,介质对出口管的密封面造成冲刷力较大,加速出口管道密封面的磨损,降低其使用寿命。
发明内容
本实用新型所要解决的技术问题是提供一种较少介质对阀体流道出料侧的密封面造成冲击力的闸板阀。
为了解决上述技术问题,本实用新型采用的技术方案是:一闸板阀,包含阀杆、阀体、闸板架,阀体内有一内腔,闸板架处于阀体内腔中,阀杆穿过阀体的上半部且下端与闸板架连接,闸板架的底端加有锥形导流孔,位于阀体流道进料侧一面的导流孔的孔径与进料侧的尺寸相同,位于阀体流道出料侧一面的导流孔处于出料侧密封面的内侧。
使用上述装置的闸板阀,当阀门打开时,介质经出口管道在经过锥形导流孔,最后从出口管道流出,由于锥形导流孔出口端的外壁处于出口管道的内壁,当介质流过时就不会再碰触出口管道的密封面,从而达到了防止介质对出口管道密封面进行冲刷的效果。
附图说明
图1为本实用新型的闸板阀的结构图。
具体实施方式
    由图1所示的结构图可知,阀体1内有一内腔,阀杆5穿过阀体1的上半部,阀杆5的下端连接有闸板架3,有一销4穿过阀杆5的下端将闸板架3固定与阀杆5上,闸板架3上设有左闸板9、右闸板11,左闸板9的右侧为阶梯状,右闸板11的左侧有一凹槽能够与左闸板9的右侧密切相配,左闸板9与右闸板11分别紧贴在阀座上8,左闸板9与右闸板11之间还连接有调节垫片10,闸板架3的下端增加有一锥形导流孔2,锥形导流孔2位于阀体流道进料侧的一端与进料侧6尺寸相同,另一端的外壁紧贴阀体流道出料侧7的内壁。
