The invention discloses a full-diameter ceramic through valve, which comprises a movable cap, a joint, a sealing gasket, a valve body, a fixed ceramic sheet, a rotating ceramic sheet, a valve stem, a ring, a valve cover, etc. The left end of the valve body is provided with a sealing gasket, the other end of the sealing gasket is connected with a movable joint cap, and the two ends of the rotating ceramic sheet are connected by a positioning pin in the middle of the fixed ceramic sheet. The assemblies are loaded into the holes of the valve body, the outer circumferential sleeve of the valve body, the valve stem penetrates into the ring sleeve and the valve body is connected with the rotating ceramic sheet, the outer handle of the valve stem is fixed with the anti-slip nut, and the right end of the fixed ceramic sheet on the right side is provided with an O-ring. After the valve cover is connected with the right end of the valve body, the movable joint cap sleeve is connected with the right end of the valve cover. The invention is composed of three ceramic sheets with an opening and closing. The function of innovative valve structure, forming a larger cross-sectional area channel, the liquid meson through the ceramic plate buffer effect to offset the flow resistance, increase the flow rate.

技术介绍
传统的球阀密封结构,由于阀球材质多为不锈钢,铁,铸铁,铜,塑料等制成,其缺点多为不锈钢造价高昂不易普及,铁及铸铁不耐腐蚀,铜和塑料不耐磨损也不耐腐蚀而且作为跟阀球配合的两个方向上的阀座是由聚四氟乙烯制成,这种材料虽然具有优良的低摩擦系数特性和耐腐蚀性是作为球阀阀座首选的材料,但在实际工作工况下难免球阀所通过的介子中带有硬颗粒物质当球阀关闭或打开时硬颗粒物质夹杂到阀球与阀座之间起密封作用的面上时,阀座密封面极易出现被硬颗粒物质永久性破坏的现象最终导致泄漏传统闸阀结构由于密封结构是由两个带一定角度的斜面挤压配合密封的,所以对通过其阀门的介子有着较高的要求,任何杂质都能对两个密封面造成永久性破坏最终导致泄漏,而且闸阀的制造工艺复杂,耗材耗能较大,整体质量也是所有阀门结构中最不稳定的,由于其特有的密封结构密封面无法做防腐镀层处理也就导致了它极差的抗腐蚀性。传统截止阀分刚性密封和软性密封但两者结构原理相同,其最大的缺点就是介子通过阀门时流向会发生90度转角出现较大的阻力,这样直接影响 ...
