Specific implementation mode
The particular content of the utility model is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, cage type throttling valve, including：Valve body 1 and valve deck 2, the valve deck 2 by fixing bolt 3 with
Valve body 1 is connected, and the lower end of the valve body 1 is provided with intake channel 4, and the side of the valve body 1 is provided with exit passageway
5, valve seat 6 is provided in the valve body 1, be provided in the valve seat 6 with intake channel 4 be interconnected first connect lead to
Road 7 is inlaid with monoblock type alloy cage set 8 in the valve seat 6, is provided in monoblock type alloy cage set 8 and connects with first
The second interconnected interface channel 9 of road 7 is connected, several throttling pores 10, institute are provided on monoblock type alloy cage set 8
It states the second interface channel 9 to be interconnected by throttling pore 10 and exit passageway 5, in the upper end of monoblock type alloy cage set 8
Outside sliding sleeve is equipped with alloy baffle ring 11, and the alloy baffle ring 11 is embedded in inside the lower end of valve rod 12, the valve rod 12 it is upper
End is stretched out valve deck 2 and is threaded through in 12 mutually matched valve stem nut 13 of valve rod, and the valve stem nut 13 is rotatably arranged on valve deck 2
Upper end, the outside of the valve stem nut 13 is provided with handwheel 14, is provided on the inner wall of the valve deck 2 and 12 phase of valve rod
The driving key 15 mutually coordinated is provided with gasket ring 16 between the valve body 1 and valve deck 2, the valve body 1 and valve rod 12 it
