Abstract
The invention discloses a ball relief valve with two overflow openings. The ball relief valve comprises a valve body, a valve element and a handle, wherein the valve element is positioned in the valve body; the handle is fixedly connected with the valve element, and can drive the valve element to rotate relative to the valve body; a channel which can be communicated with a valve cavity is arranged in the middle of the valve element; overflow devices for unloading are respectively connected with two ends of the valve body; the overflow devices positioned at the two ends of the valve body adopt the same structures; a pressure division channel is arranged on the valve body and the valve element, and corresponds to the overflow devices. When the pressure of a system is excessive, redundant pressure can be released by extruding the overflow devices, so that the system is effectively protected from local burst and the system safety is improved.
