The utility model relates to the field of water valve structure, in particular to a pedal delay flushing valve, which comprises a valve body and a valve core. The valve body comprises an outer valve body and an inner valve body clamped inside the outer valve body. A valve body seal ring is arranged between the outer valve body and the inner valve body, an outer water inlet and an outer water outlet are arranged between the outer valve body and the inner valve body, and a cover plate is arranged above the outer valve body through an outer locking nut, and an inner water inlet and an inner valve body are arranged. The inner outlet is provided with a spool, the upper end of the spool extends upward through the cover plate and is arranged above the cover plate. The spool is located at one end above the cover plate with a pedal. The spool is provided with an upper return spring between the pedal plate and the cover plate. A floating spool is arranged below the spool, and a lower return spring which can seal the inner inlet from the bottom to the top is arranged below the floating spool. The utility model solves the problems that the existing mechanical water valves need to be operated by hand and are liable to cause disease infection, and the induction water valves have complex structure, potential safety hazards of electricity consumption and waste of electric energy, and can also improve the water-saving capacity.
【技术实现步骤摘要】
一种脚踏延时冲洗阀
本技术涉及水阀结构领域,尤其涉及一种脚踏延时冲洗阀。
技术介绍
现在的水阀通常有机械式和感应式两种,机械式水阀才有机械结构实现水阀的启闭,在启闭的过程过需要手按压或旋转,这种水阀容易导致细菌交叉感染,从而导致疾病的传播,因此,在医院、公共厕所、宾馆、学校等公共场所的机械水阀正在逐渐被淘汰。感应式水阀是为了克服上述机械式水阀的缺点而发展起来的,只要手伸到其感应窗的前方,水阀就会自动开启,手离开感应窗水阀就自动关闭,其主要原理就是利用红外线感应信号触发电磁阀的开启和关闭来实现水阀的启闭。这种感应式水阀的缺点是结构较复杂、成本高,由于需要电源,存在用电安全隐患,浪费电能。
技术实现思路
因此,针对上述的问题,本技术提出一种脚踏延时冲洗阀,解决现有机械式水阀要用手接触进行操作而易引起疾病传染,以及感应式水阀结构复杂、存在用电安全隐患、浪费电能的问题,同时还可以提高节水能力。为实现上述目的,本技术采用了以下技术方案:一种脚踏延时冲洗阀,包括阀体和阀芯,所述阀体包括外阀体和卡置在外阀体内部的内阀体,所述外阀体和内阀体之间设有阀体密封圈,所述外阀体设有外进水口和外出水口,所述外阀体上方通过外锁紧螺母设有盖板,所述内阀体设有内进水口和内出水口,所述内阀体设有阀芯,所述阀芯上端向上延伸穿过盖板设于盖板上方,所述阀芯位于盖板上方的一端设有脚踏板,所述阀芯于脚踏板和盖板之间设有上回位弹簧,所述阀芯下方设有浮动阀芯,所述浮动阀芯下方设有可将其由下向上将内进水口密封的下回位弹簧。进一步地改进,所述阀芯中部设有用于固定阀芯的环形凸台,所述凸台外表面设有与内阀体内壁紧密接触 ...
