【技术实现步骤摘要】
一种新型刀阀
本技术涉及刀阀领域,具体是一种新型刀阀。
技术介绍
刀阀的闸板运动方向与流体方向垂直,靠可以切断纤维材料的刀刃型闸板来切断介质,现有的刀阀存在着许多缺陷,例如闸板易变形,刀阀的耐腐蚀性较差,无法很好的清理刀阀内壁的结垢,而且手轮操作相对不便。
技术实现思路
本技术的目的在于提供一种新型刀阀,以解决现有技术中的手轮操作相对不便、耐腐蚀性较差、闸板易变形和刀阀内壁的结垢清理不便问题。为实现上述目的,本技术提供如下技术方案:一种新型刀阀,包括阀体、闸板、阀盖和阀杆,所述阀体外表面上设置有排气孔,所述排气孔上安装有中空管,所述阀体内壁安装有阀体内衬,所述阀体内部安装有闸板,所述闸板和阀体内壁交接处设置有耐磨合金凸起,所述闸板和阀杆一端连接,所述阀杆通过固定条和闸板连接,所述固定条两端通过紧固螺栓和闸板连接,所述阀杆另一端穿出阀体和阀盖,所述阀盖可拆卸安装在阀体上侧,所述阀杆上端安装有手轮,所述手轮上侧焊接有力臂杆,所述阀盖内部设置有上压紧垫和下压紧垫,所述上压紧垫和下压紧垫之间设置有填料。优选的,所述阀体内衬为陶瓷内衬。优选的,所述固定条上设置有凹槽,凹槽卡接在阀杆上。优选的,所述耐磨合金凸起边缘处呈刀型刃口。优选的,所述力臂杆上设置有防滑螺纹。优选的,所述中空管上设置有通孔。与现有技术相比,本技术的有益效果是:本技术通过阀体内衬为陶瓷内衬,能够很好的提高该设备的耐腐蚀性,通过固定条上设置有凹槽,凹槽卡接在阀杆上,能够很好的避免闸板变形,通过耐磨合金凸起边缘处呈刀型刃口,能够很好的对阀体内壁的结垢进行清理,通过力臂杆上设置有防滑螺纹,很好的提高了手轮转动的方 ...
