Zusammenfassung:The utility model provides a novel pressure reducing valve which comprises a valve body, a valve rod, a valve rod central rod, a main spring, an auxiliary spring, an air inlet interface, an air outlet interface and an automatic plugging device. The automatic plugging device comprises a housing, a valve element, a reset spring and through holes, wherein the housing comprises a front housing and a rear housing, the front housing is arranged in the air outlet interface, the rear housing is clamped and connected in the front housing, the housing is provided with the inner cavity communicated with the air outlet interface, the valve element is arranged in the inner cavity, multiple through holes are formed in the valve element and communicated with the inner cavity, and the reset spring is arranged on the outer surface of the valve element in a sleeving mode. The novel pressure reducing valve has the advantages that the novel pressure reducing valve is simple and compact in structure, quick and convenient to assemble and install and good in pressure reducing effect, facilitates replacement or overhaul and enables pressure reducing regulation to be convenient and effort-saving; elastic force of the auxiliary spring is further adjusted by regulating and screwing a compression nut of a first screw and a compression nut of a second screw, and the internal sealing performance of the valve body can be higher.
