Zusammenfassung:	The invention discloses a water pipe check valve rotation rack and relates to the technical field of valves. The water pipe check valve rotation rack is characterized by comprising a fixed rack, a limit rack and a rotary bolt. The fixed rack is fixedly connected with the rotary bolt. The limit rack is rotatably mounted on the fixed rack through the rotary bolt. Two 90-degree sector rotary grooves are formed in the rotary bolt. One lateral side, located on the rotary grooves, of the rotary bolt is provided with two rotary retaining plates which are vertical to the limit rack. The rotary retaining plates and the rotary grooves are symmetrical relative to the center of the rotary bolt. The water pipe check valve rotation rack is simple in structure, reasonable in design, convenient to use, good in check effect, and less prone to getting stuck and leakage.
