Description

一种防倒流外堵型喷嘴
技术领域
本发明涉及喷嘴,特别涉及一种防倒流外堵型喷嘴。
背景技术
喷雾降尘技术主要是通过喷嘴将高压水喷出,高压水在被喷出的瞬间破碎而在喷嘴前形成喷雾场。由于水滴对粉尘具有捕集作用,从而降低生产环境中的粉尘浓度。喷雾降尘装置其主要结构为雾化喷嘴,但在喷嘴使用过程中的堵塞主要分为内堵与外堵,内堵由于水质不良造成的,通常加装过滤网便可解决。外堵主要是由于外部环境粉尘在喷嘴停用时通过喷嘴通孔进入喷嘴内腔导致喷嘴堵塞。传统的压力喷嘴由于结构设计缺陷,必须停水停泵然后由工人对喷嘴逐个进行清理才能恢复工作,严重影响工作效率。因此如何能够使喷嘴在停止喷雾后自动堵住喷雾孔,如何防治粉尘进入喷嘴内腔,如何防止水倒流进入喷嘴内腔,是喷雾降尘装置上一个亟待解决的问题。
故此,现有的喷嘴需要进一步改善。
发明内容
本发明的目的是为了提供一种防倒流外堵型喷嘴,能多层防堵结构,有效防止粉尘和水分倒流堵住喷嘴。
为了达到上述目的,本发明采用以下方案:
一种防倒流外堵型喷嘴,包括阀体,所述阀体内设置有阀腔,所述阀体一端设置有和阀腔连通的进水口,另一端设置有阀腔连通的出水口,所述阀腔内的进水口边缘设置有下凹槽,所述阀腔内设置有滑动轨道,所述滑动轨道上活动设置有堵塞杆,所述堵塞杆两侧各设置有用于将所述阀腔分为两个独立腔体的阻挡板,所述堵塞杆上设置有配合所述下凹槽封闭所述进水口的凸块,所述堵塞杆和所述滑动轨道之间设置有用于将所述堵塞杆推送至所述下凹槽方向的弹性机构,所述阀腔上下对称设置有翻转杆,所述翻转杆外端设置有封闭板,所述堵塞杆上设置有穿过两个所述翻转杆之间的密封杆,所述密封杆上下表面各设置有第二铰接座,所述翻转杆上设置有第三铰接座,所述第二铰接座和对应一侧所述第三铰接座之间铰接有驱动连杆,所述堵塞杆内衍射至所述凸块端面开设有排水道,所述排水道内壁和所述堵塞杆外壁之间设置有多个排水孔。
进一步地,所述下凹槽和所述凸块的形状相同。
进一步地,所述下凹槽为下凹的锥形槽,所述凸块为外凸的锥形块。
进一步地,所述滑动轨道包括有设置在所述阀腔内的上下两个基座,所述基座上设置有横导向杆,所述阻挡板上下方各设置有导向孔,所述导向孔套设在对应一侧所述横导向杆外活动。
进一步地,所述弹性机构为弹簧体,弹簧体套设在所述横导向杆外,一端压紧所述基座表面,另一端压紧所述导向孔表面。
进一步地,所述翻转杆包括有设置子在所述阀腔内的第一铰接座,所述第一铰接座上铰接有摆动杆。
进一步地,所述翻转杆靠近所述密封杆一侧的表面设置有密封条。
进一步地,所述封闭板为弧形设置,靠近所述阀腔一侧壁设置有弧形收纳槽,所述弧形收纳槽和所述封闭板的弧度相同。
进一步地,所述封闭板外表面设置有导流凹槽。
进一步地,所述进水口设置有两个分流口分别连通至所述阻挡板上下表面。
综上所述,本发明相对于现有技术其有益效果是:
本发明解决了现有喷嘴中存在的不足,在保证喷嘴喷水流畅性的基础上,还能保证喷嘴喷水停止后防止粉尘堵塞喷水口,同时,还具备防止外界水源倒流至喷嘴内腔,避免了人工疏通喷水口的麻烦,使用方便,且结构简单,使用方便。

当进水口2停止进水时,阻挡板17失去了压力,此时凸块80复位贴紧下凹槽5表面,形成第一道密封口,两侧的封闭板10相互靠拢密封,形成第二道密封口,二道密封。
本发明所述下凹槽5和所述凸块80的形状相同。
本发明所述下凹槽5为下凹的锥形槽,所述凸块80为外凸的锥形块。
本发明所述滑动轨道6包括有设置在所述阀腔4内的上下两个基座601,所述基座601上设置有横导向杆602,所述阻挡板17上下方各设置有导向孔603,所述导向孔603套设在对应一侧所述横导向杆 602外活动。
本发明所述弹性机构8为弹簧体,弹簧体套设在所述横导向杆 602外,一端压紧所述基座601表面,另一端压紧所述导向孔603表面。
本发明所述翻转杆9包括有设置子在所述阀腔4内的第一铰接座 901,所述第一铰接座901上铰接有摆动杆902。
