The invention discloses a delay valve, comprising a valve body, the valve body is provided with a water inlet and a water outlet, the inner cavity of the valve body is provided with a first partition and the first partition board is provided with a through hole, the first divides the inner cavity of the valve body is divided into a water inlet cavity and a water outlet chamber, the water inlet and the water outlet cavity through the through hole communicated with the water inlet cavity, a valve seat is arranged. The valve seat is arranged in the second partition, second seat partition will be divided into a water inlet chamber and the valve chamber, a valve spool installed indoors, a spring is arranged between the valve core and the second partition and the spool can be through hole plugging on the first clapboard in the water chamber and communicated with a water inlet valve seat, the side wall of the water inlet chamber is provided with a water inlet hole communicated with the the cavity, a push rod can push the spool mounted water cavity, the second baffle is arranged on the water inlet hole communicated with the water inlet chamber and the valve chamber; the invention in the external water pressure reduction Combined with the spring, increasing the force of the valve reset, reducing the valve reset time, reducing the amount of water once washed, is conducive to water conservation.
【技术实现步骤摘要】
本专利技术涉及一种阀门,特别是一种延时冲洗阀。
技术介绍
传统用于冲洗的延时阀包括阀体,在阀体上设置有进水口和出水 口,阀体内腔设置有第一隔板,第一隔板上设置有通孔,第一隔板将 阀体内腔分隔成进水腔和出水腔,进水腔和出水腔通过通孔连通,进 水腔内安装有阀座,阀座内设置有第二隔板,第二隔板将阀座分隔成 进水室与阀芯室,阀芯室内安装有阔芯,阀芯与第二隔板之间安装有弹簧,阀芯可封堵隔板上的通孔,阀座的进水室与进水口相通,进水 室的侧壁设置有进水腔连通的水孔,出水腔内安装有可顶抵阀芯的顶 杆。传统延时阀阀芯的复位是通过弹簧的弹力来实现的,弹簧弹力的 大小决定阀芯的开启时间,从而决定冲洗用水量。由于弹簧的弹力通 常比较小,并且弹簧在长期使用后弹力会逐渐衰减,因此阀芯的复位 时间较长, 一次冲洗水量较大。
技术实现思路
为了克服现有技术的不足,本专利技术提供一种可减少阀芯复位时 间、降低一次冲洗水量的延时阀。本专利技术解决其技术问题所采用的技术方案是一种延时阀,包括阀体,阀体上设置有进水口和出水口,阀体内 腔设置有第一隔板,第一隔板上设置有通孔,第一隔板将阀体内腔分隔成进水 ...
