| description | The invention relates to a low-temperature regulating valve technology, in particular to a high-leakproofness low-temperature regulating valve which is used for solving the problems that particulate matter impurities contained in a low-temperature medium cause adverse effects on the leakproofness of the regulating valve and the overhauling work is inconvenient to carry out due to the fact that the distance between an overhauling opening and a fixing ring is large. According to the low-temperature medium circulating valve, particulate matter impurities in a low-temperature medium circulating in the valve cylinder are filtered out through the filter screen frame, so that the particulate matter impurities cannot cause adverse effects on tight closing of the valve clack and the fixing ring, and an outer gear ring in a rotating frame is driven by a rotating gear and a gear to rotate; a clamping frame in the outer gear ring is clamped at the position of a clamping groove in a connecting rod, so that when a driving |
