【技术实现步骤摘要】
本技术属于阀门
,涉及一种带助力装置的阀门启闭装置。
技术介绍
现有阀门启闭装置通常利用手轮结构,用手掌转动打开阀门,但某些阀门可能由于长时间呈未打开状态,使得连接部分生锈,较难打开,因此有必要进行改进。
技术实现思路
本技术的目的是针对现有技术中存在的上述问题,提供了一种能使打开阀门更加省力的带助力装置的阀门启闭装置。本技术的目的可通过下列技术方案来实现:一种带助力装置的阀门启闭装置,包括手轮,手轮包括内圈和外圈,及连接内圈和外圈的轮辐,其特征在于:外圈内沿和外沿分别设有内弧形槽和外弧形槽,且内弧形槽和外弧形槽之间通过穿孔贯穿,还包括弧形助力杆,助力杆穿过穿孔,且助力杆内端和外端分别置于内弧形槽和外弧形槽内,且助力杆通过销钉与外圈可转动连接,且销钉沿手轮轴向设置,并设在穿孔内,且能围绕销钉转动助力杆,使助力杆内端抵在内圈外沿上,并使助力杆外端从外弧形槽内旋出,且能握持并推动助力杆外端,并转动所述的手轮,以打开被手轮控制的阀门。使用时,可以直接通过旋转外圈打开阀门,当阀门打不开时,可以围绕销钉转动助力杆,使助力杆内端抵在内圈外沿上,并使助力杆外端从外弧形槽内旋出,且能握持并推动助力杆外端,并转动手轮,以打开被手轮控制的阀门,而且助力杆不使用时,整体置于外圈内,避免对手轮造成影响,因此本启闭装置可以通过传统手轮方式打开阀门,也能利用助力杆助力,以更加省力打开阀门。在上述的一种带助力装置的阀门启闭装置中,所述的内圈外沿设有缺口槽,且能旋转助力杆,使助力杆内端抵在缺口槽内。因此助力杆使用时更加稳定。在上述的一种带助力装置的阀门启闭装置中,所述的内弧形槽槽底设 ...
