One-way throttle valve

The invention discloses a one-way throttle valve. The one-way throttle valve comprises an outer ring valve body and an inner ring valve body, the top end of the inner ring valve body is sleeved with avalve deck, the valve deck is connected with the inner ring valve body through bolts, a throttle valve element is embedded in the inner ring valve body, a plurality of rib plates are connected to thethrottle valve element in a guiding and sliding mode, and the outer side of the inner ring valve body is sleeved with a one-way valve element. The one-way throttle valve is scientific and reasonablein structure and safe and convenient to use, the one-way throttle valve is simple in structural design, reliable in work and durable, mechanical moving parts such as a lever, a connecting rod and a rotating shaft do not exist in the one-way throttle valve, and failures caused by faults such as mechanical abrasion, dislocation, jamming, breakage, deformation and open welding cannot occur; and the throttle valve element and t
