The invention belongs to the technical field of pressure regulating valves, and particularly relates to a double-valve-port air pressure regulating valve. The pressure regulating valve comprises a valve body, the lower end of the valve body is connected with a spring box, the upper end of the valve body is connected with an upper cover, an inflation and deflation valve is arranged in the upper cover in a sleeved mode, a valve spring is arranged between the inflation and deflation valve and the upper cover, a valve seat is arranged in the valve body, and the valve seat divides the interior of the valve body into an upper input cavity and a lower output cavity. A pressure adjusting spring assembly is installed in the spring box, one end of the pressure adjusting spring assembly is connected with a piston, a piston cavity is formed between the valve body and the piston, the piston is connected with a piston rod, the piston rod is connected with an exhaust valve rod, and the exhaust valve rod penetrates through the valve seat and is tightly attached to the bottom of the inflation and exhaust valve. A small hole communicated with the output cavity and the piston cavity is formed in the valve body, and an exhaust port is formed in the spring box. The invention provides the double-valve-port air pressure regulating valve capable of automatically exhausting or supplying air when an error exists between the output pressure and the preset pressure regulating value.

    本发明属于调压阀技术领域,特别涉及一种双阀口空气压力调压阀。本发明的调压阀包括阀体,阀体下端连接有弹簧盒,阀体上端连接有上盖,上盖内套设有充排气阀,充排气阀与上盖之间设置有阀簧,阀体内设置有阀座,阀座将阀体内部分隔成上部的输入腔和下部的输出腔;弹簧盒内安装有调压弹簧组件,调压弹簧组件的一端连接有活塞,阀体与活塞之间形成活塞腔,活塞上连接有活塞杆,活塞杆上连接有排风阀杆,排风阀杆穿过阀座并与充排气阀的底部密贴;阀体上设置有连通输出腔与活塞腔的小孔,弹簧盒上设置有排气口。本发明提供了一种输出压力与预定调压值有误差时自动排气或补给的双阀口空气压力调压阀。
