The side of body is provided with exit passageway, and valve seat is provided with the valve body, is provided with the valve seat and intake channel phase
The first intercommunicated interface channel, monoblock type alloy cage set is inlaid with the valve seat, in monoblock type alloy cage set
The second interface channel being interconnected with the first interface channel is provided with, some sections are provided with monoblock type alloy cage set
Aperture is flowed, second interface channel is interconnected by throttling pore and exit passageway, in monoblock type alloy cage set
Slip cap is provided with alloy baffle ring on the outside of upper end, and the alloy baffle ring is embedded in inside the lower end of valve rod, and the upper end of the valve rod is stretched
Go out bonnet to be located in the valve stem nut to cooperate with valve rod, the valve stem nut is rotatably arranged on the upper end of bonnet, in institute
State and handwheel is provided with the outside of valve stem nut, the driving key to be cooperated with valve rod is provided with the inwall of the bonnet,
Gasket ring is provided between the valve body and bonnet, sealing ring is provided between the valve body and valve rod.
It is an advantage of the invention that：Above-mentioned cage type throttling valve, structure is novel, easy to use, employs monoblock type alloy cage
Nested structure, and set multiple throttle orifices to be throttled on monoblock type alloy cage set, flushing resistance is good, and throttling is stable, noise
It is low, the trouble for frequently changing throttle valve seat is avoided, operating efficiency is high.
