The invention provides an overflow pressure reducing output structure and a plate-connected overflow pressure reducing valve. The structure comprises a piston part, a moving part, and a fixedly arranged seat body surrounding the moving part, wherein the piston part is in contact with one end of the moving part, the side, not in contact with the moving part, of the piston part, and the end, not incontact with the piston part, of the moving part are connected with a spring part in a compressed mode, the inner part of the piston part is axially penetrated and a channel is formed, and in a compressed state, the moving part abuts against the channel and closes the channel; when fluid is introduced from an input end, the piston part and the moving part move towards one side of the piston part together, and the fluid is output from an output end until the moving part is limited by the seat body; when the pressure at the output end increases, the piston part is separated from the moving part,the fluid flows out from a discharging port of a valve cavity after passing through the channel, and the piston part makes contact with the moving part again, so that the pressure reducing output structure is improved, and the overflow functions of the pressure reducing output structure and the pressure reducing valve adopting the pressure reducing output structure are achieved.
本发明提供一种溢流减压输出结构及板接式溢流减压阀,包括活塞部和运动件,活塞部与运动件的一端接触,活塞部未与运动件接触的一侧、以及运动件未与活塞部接触的一端都与弹簧件连接压紧,活塞部内部轴向贯通并形成通道,且压紧状态下,运动件与该通道相抵并使得该通道关闭,其中,还包括固定设置并环设运动件的座体,当流体从输入端通入时,所述活塞部与运动件一并朝向活塞部一侧的运动,流体从输出端输出,直至运动件被座体限位;当输出端压力增大时,活塞部与所述运动件分离,流体经过通道后从阀腔的排口流出,则活塞部重新与所述运动件接触,从而在改进减压输出结构的同时,使得减压输出结构和运用该减压输出结构的减压阀实现溢流功能。
