The utility model discloses a new butterfly valve, which comprises a fixing plate, an opening and closing mechanism and an operating mechanism. The fixing plate is circumferentially uniformly provided with three mounting seats and fixed connections. The opening and closing mechanism is fixed connected with the fixing plate. The opening and closing mechanism comprises a disc plate, a connecting plate and a ring keel. The disc plate and a connecting plate are provided with four parts. The disc plate is provided with a hinged ear and two hinged ears. The hinged ear is hinged with a fixed plate. The disc plate and the connecting plate are hinged by two hinged ears. The connecting plate and the annular keel are fixed and connected. The operating mechanism includes the hinged ear three and the operating rod. The operating rod is hinged with a set of connecting plates through the hinged ear three. The new disc plate is divided into four parts, and the movement track of the operating mechanism is up-and-down reciprocating, which makes the disc plate open and close faster and simpler than the butterfly valve in ordinary life. When the disc plate is fully opened, there is no middle rotating rod, so that the water intake and air intake are not affected by resistance, and the flow rate is more stable.
【技术实现步骤摘要】
一种新型蝶阀
本技术属于蝶阀
,具体地说,本技术涉及一种新型蝶阀。
技术介绍
目前常见的蝶阀的碟板都是圆形,操纵其旋转的大部分也都是旋转开关,而操纵工都是成年男性居多,故若出现紧急情况,比如家居天然气泄漏,进水管路漏水,而这种情况恰恰女性,老人和孩子居家较多,若旋转发生锈死,女性与孩子的握紧力也不够大,这样容易酿成安全事故。申请号CN201320312754.1的中国专利,种新型多功能信号卡箍蝶阀,包括启闭手柄、止动刻度盘、执行机构、阀体、阀板和阀轴,还包括开关信号指示灯,开关指示灯与一信号装置相连接,所述阀轴孔为正方体或长方体,所述阀轴为与阀轴孔紧密嵌合的正方体或长方体。本技术结构简单、功能较多,该卡箍蝶阀安装有开关信号指示灯、微动开关,微动开关控制开关信号指示灯的开启,使用方便,便于对其维修,提高了工作效率。另外,阀板板体外表面固装一橡胶层,从而该包胶蝶阀阀板可以直接与阀体相接触,而不需要再在阀板上安装阀座,不但结构简单、制作方便、密封性好,提高了阀板的使用寿命,而且简化了安装的步骤,降低了生产成本。
