| description | The invention discloses a high-flux reverse osmosis prevention check valve, and relates to the technical field of liquid check valves. The overflow check valve comprises an overflow pipe body and a check valve core body, the check valve element body comprises a packaging frame, a first sealing ring, a reset spring and a check plug. A baffle ring is arranged in the middle of the inner wall of the overflowing pipe body, and the first sealing ring is packaged between the packaging frame and the baffle ring; the conical surface of the plug surface end of the non-return plug is in interference sealing fit with the first sealing ring; the supporting column end of the non-return plug is in axial sliding guide fit with the packaging frame. The return spring is arranged outside the non-return plug supporting column in a sleeving mode and used for pushing the non-return plug to the first sealing ring. The downstream energy storage pipe body is constructed to be installed in the downstream overflowing pipe body of the c |
