The invention discloses a butterfly double flap one-way valve reverse resistance device, which comprises a push-pull type traction electromagnet, a rocker with a V-shaped port, a stainless steel braided soft joint and an outer wire short joint. The butterfly double flap one-way valve reverse resistance device drives the V-shaped port rocker to swing under the action of the push-pull type traction electromagnet, and the resistance of the butterfly double flap one-way valve is relieved through the V-shaped rocker. V-shaped rocker and push-pull traction electromagnet are connected by movable bolts, one end of stainless steel braided hose is welded and sealed with V-shaped rocker, the other end is connected with external short wire joint welded on the pipeline by nuts, the V-shaped rocker is connected with external short wire joint steel handle to produce a limit fulcrum, and the V-shaped rocker can be connected with the limit fulcrum and push-pull traction electromagnet Swing, used to limit the reaction force of the disc. When the electromagnet is powered off, the V-port rocker is separated from the valve disc by the force of the electromagnet spring, and the valve disc is closed rapidly under the force of its own spring, so as to realize the function of one-way reverse flow. After the resistance of the one-way valve is released, the frequency conversion space of the water pump can be increased and the operation power consumption of the water pump can be reduced.
【技术实现步骤摘要】
蝶形双瓣单向阀逆阻装置
本专利技术涉及一种水泵单向阀逆阻装置,尤其用于蝶形双瓣单向阀。
技术介绍
在暖通空调的冷冻水、冷却水系统中,在水泵出口处安装了一个允许水流单向运动的单向阀,该单向阀可以在水泵停止时迅速关闭防止水流逆流及产生水锤现象,蝶形双瓣单向阀由阀体、阀瓣1、阀瓣2及弹簧组成,阀瓣1、阀瓣2在弹簧的反作用力下处于关闭状态,当水泵启动水流冲击阀瓣时,水流冲击力大于阀瓣弹簧的反作用力时,阀瓣缓缓开启直至90°全部打开,一旦阀瓣打开不管其开度多大,阀瓣的弹簧始终对阀瓣产生一个关闭的作用力,最终作用在水流上,水流时刻要克服弹簧的反作用力,因此水泵的功耗一部分用于克服单向阀阀瓣的阻力,尤其在水泵降频运行时,由于水泵的扬程随着电机频率降低快速下降,但此时仍要克服单向阀的阻力,因此降频的空间被缩小,无法最大程度节约运行费用。蝶形双瓣单向阀其缺点是:阀瓣只要开启无论角度大小都受到弹簧的反作用力,此时水流经过阀瓣时也承受了弹簧反作用力,当阀瓣开启角度小时,水流不仅受到弹簧的反作用力,同时阀瓣本身也阻挡了水流,迫使水泵加大转速 ...
