A pressure reducing valve installed inside the inverse pressure discharging device integration, which comprises a valve sleeve body, which is characterized in that one side of the entrance flow the other side forms a cylindrical side outlet configuration has a valve sleeve body cover, a cylindrical valve cavity of a valve sleeve is arranged inside the guide hole and the formation fluid flows into the mouth into the middle the easy from the outlet discharge a lot; according to the inverse pressure, movement and at the same time set in the valve cavity and the upper guide hole of the opening and closing of the diaphragm, high pressure and unstable pressure into the water or liquid fluid to adjust valve pressure relief valves of the valve gate is formed; in the center of the inverse pressure regulating valve is inlaid in the configuration of the center channel inverse pressure guide hole, and the bottom of a wide valve head disc, inverse pressure inside the flow channel on the side through the elastic contact to the upper end of the valve head branch The bottom surface of the flange spring lug and the circumferential direction, inverse pressure to the valve head center inverse pressure guide hole to side mobile, inverse pressure discharging device from the valve on the side of the inverse pressure outflow hole from the inverse pressure discharging part.
【技术实现步骤摘要】
本技术属于减压阀门
，具体地说是一种内部安装逆压排放装置的一体化减压阀门。根据本结构，当减压阀门的流出孔上产生的逆压向上侧推动隔膜时，调节阀同时上升，连接在下端的阀头堵住与流入口相连的阀门腔下端的引导孔，切断排出流体的流入，而安装在调节阀中心的逆压排放装置从流入孔排放逆压，使流出孔内部保持稳定的流体流动。
技术介绍
一般而言，市面上有多种形式的能够把不稳定的流体压力调整到一定压力的减压阀门。举例来说，图1是通常使用的减压阀门，其内容如下。如图所示，从一侧没有标明的配管中流入的温水或蒸汽等流体(HD)流入到流入口(IS)，上面有相互结合的圆盘(DS)和隔膜(DP)，靠圆盘(DS)上面的弹簧(SP)弹力构成控制流入口(IS)流体流动的控制阀(CV)，控制阀(CV)的下端形成圆盘形阀头(VH)。阀头(VH)的上面有引导流入孔(IS)流体到流出孔(OS)的引导孔(IH)，通过引导孔(IH)流向流出孔(OS)的流体压力增大时，产生逆压(BP)而推动隔膜(DP)上升，阀头(VH)就能堵住引导孔(IH)而切断流体的流入，当压力下降到设定压力以下时，圆盘(DS)上面的弹簧...
