Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.
As shown in figure 1, double disclosed in the utility model open double Cutoff ball valves, including valve body 3, valve seat 4, drift ping 5, flap 6,
Bonnet 9, bottom 1, upper valve rod 8, driver 14 and lower valve rod 2, bonnet 9 and the top of valve body 3 are affixed, and bottom 1 is consolidated with the bottom of valve body 3
Connect, drift ping 5 is slidably connected by the dovetail groove of its opposite sides with two independent flaps 6, i.e., has dovetail groove, valve on drift ping 5
There is the dovetail being adapted to dovetail groove on valve 6.There is through flow hole on drift ping 5, through flow hole is located at the middle part of drift ping 5.The bottom of drift ping 5 is set
Through hole is equipped with, bottom 1 is provided with the lower valve rod 2 to match with the through hole；The one end of upper valve rod 8 passes through bonnet 9 and the drift ping in valve body 3
5 connections, the other end of upper valve rod 8 are connected with driver 14, and the outer surface of flap 6 is sphere, and the upstream and downstream of valve body 3 is mounted on valve
Seat 4, the sealing surface of valve seat 4 is sphere.
The mode that moves up and down of limitation flap 6 has a lot, can increase limited block can also directly by bonnet and bottom Lai
Limitation.By setting limited block 7 to be moved up and down to limit flap 6 in present embodiment, as shown in figure 1, flap 6 and bonnet 9 it
Between, limited block 7 is respectively provided between flap 6 and bottom 1.
Double pair Cutoff ball valves of opening also include support 12, and the bottom of support 12 and the top of bonnet 9 are affixed, and the top of support 12 is with driving
Dynamic device 14 is affixed, and the other end of upper valve rod 8 is connected through support 12 with driver 14.There is filler 10 between upper valve rod 8 and bonnet 9,
There is packing press ring 11 outer end of filler 10.
Axle sleeve 12 is provided between upper valve rod 8 and support 12, has guide groove 15 on axle sleeve 12, guiding is installed on upper valve rod 8
Pin 16, guide finger 16 are slidably matched with guide groove 15.Preferably, guide groove 15 includes straightway and spiral section, straightway with
Spiral section bottom is connected smoothly, straightway and diameter parallel, and spiral section is the dextrorotation arc groove to be formed an angle with axis.
