Two hard sealing O type ball valves are installed together, and are divided into the valve of import and export side two, to ensure deslagging dust removing system overall operation.
This kind of valve is referred to as combination valve, because the execution step of this kind of valve is very strict, the switching sequence of two ball valves
It must strictly regulate, if misoperation, can cause to cause stuck phenomenon inside valve pocket, thus this kind of valve can be described as linkage again
Ball valve, i.e., carry out the folding order of linkage specification valve by drive component.But the unreasonable structure of existing linkage ball valve, two
Spacing between O type ball valves is larger, so as to cause ball valve bulky, need to improve.
The content of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of linkage ball valve, the linkage ball valve with often
The double spherical ball valves of rule compare the centre-to-centre spacing for shortening two spheroids, reduce valve mechanism length, have saved cost.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
A kind of linkage ball valve, including valve body, and it is arranged on the first spheroid and the second spheroid of valve inner, the valve body
Inside is provided with valve flowing channel, and the first valve pocket and the second valve pocket set gradually along valve flowing channel direction；First spheroid
Be arranged in the first valve pocket, the second spheroid is arranged in the second valve pocket, the first spheroid and the second spheroid provided with can with it is described
The spheroid runner that valve flowing channel is communicated；It is characterized in that：The centre of sphere between first spheroid and the second spheroid is less than the apart from a
The radius R1 of one spheroid and the radius R2 sums of the second spheroid；The spheroid lateral wall of second spheroid is provided with spheroid groove；
When the first spheroid and the second spheroid are closed, the rear end face of the first spheroid is embedded in the spheroid groove of the second spheroid
It is interior.
Preferably, the valve body of the first valve pocket upper end is provided with the first upper valve rod, the valve body of the first valve pocket lower end
Provided with lower valve rod；First spheroid is fixed spheroid, and the bottom of the first upper valve rod is fixed on the first spheroid, under the first spheroid
End is positioned on lower valve rod；The valve body of the second valve pocket upper end is provided with the second upper valve rod, and the second spheroid is floating spheroid,
The bottom of second upper valve rod is fixed on floating spheroid.
Preferably, the upper end of first upper valve rod is connected with the first drive component, the upper end of the second upper valve rod
It is connected with the second drive component.
The utility model uses above-mentioned technical proposal, and the technical scheme is related to a kind of linkage ball valve, in the linkage ball valve
Valve inner is provided with the first spheroid and the second spheroid, and the centre of sphere between the first spheroid and the second spheroid is less than the first spheroid apart from a
Radius R1 and the second spheroid radius R2 sums；The spheroid lateral wall of second spheroid is provided with spheroid groove；When first
When spheroid and the second spheroid are closed, the rear end face of the first spheroid is embedded in the spheroid groove of the second spheroid.It is above-mentioned
The linkage ball valve of structure shortens the centre-to-centre spacing of two spheroids, reduces valve mechanism length, save compared with conventional double spherical ball valves
About cost.
Brief description of the drawings
Structure sectional view when Fig. 1 is ball valve closed mode.
Structure sectional view when Fig. 2 is ball valve open mode.
Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is described in further detail.
A kind of linkage ball valve as shown in Figure 1 and 2, including valve body 1, and it is arranged on the He of the first spheroid 2 inside valve body 1
Second spheroid 3, the inside of valve body 1 is provided with valve flowing channel 11, and the first valve pocket set gradually along the direction of valve flowing channel 11
12 and second valve pocket 13.First spheroid 2 is arranged in the first valve pocket 12, and the second spheroid 3 is arranged in the second valve pocket 13, the
One spheroid 2 and the second spheroid 3 are provided with the spheroid runner that can be communicated with the valve flowing channel 11.Specifically, described first
The valve body 1 of the upper end of valve pocket 12 is provided with the first upper valve rod 14, and the valve body 1 of the lower end of the first valve pocket 12 is provided with lower valve rod 15；First
Spheroid 2 is fixed spheroid, and the bottom of the first upper valve rod 14 is fixed on the first spheroid 2, and the bottom of the first spheroid 2 is positioned at
On lower valve rod 15；The valve body 1 of the upper end of second valve pocket 13 is provided with the second upper valve rod 16, and the second spheroid 3 is floating spheroid, the
The bottom of two upper valve rods 16 is fixed on floating spheroid.
The upper end of first upper valve rod 14 is connected with the first drive component 17, the upper end connection of the second upper valve rod 16
There is the second drive component 18；First drive component and the second drive component use linkage structure as described in the background art, its
Structure for it is conventional existing therefore do not do it is tired state, and its using effect is in valve-closed state, it is necessary to first open the first spheroid 2
（Fix spheroid）, then could open the second spheroid 3（Float spheroid）；In valve opening state, it is necessary to first close second
Spheroid 3（Float spheroid）, then could close the first spheroid 2（Fix spheroid）.
The centre of sphere between the spheroid 3 of first spheroid 2 and second is less than the radius R1 and the second ball of the first spheroid 2 apart from a
The radius R2 sums of body 3.Specifically, the spheroid lateral wall of second spheroid 3 is provided with spheroid groove 31；When the first spheroid
2 and second spheroid 3 when being closed, the rear end face of the first spheroid 2 is embedded in the spheroid groove 31 of the second spheroid 3.On
State in structure, floating ball valve spheroid digs a groove, a fixing ball valve spheroid part can be embedded in floating ball valve spheroid groove 31,
But do not contacted with floating ball valve spheroid, this structure shortens the centre-to-centre spacing of two spheroids, reduced compared with conventional double spherical ball valves
Valve mechanism length, has saved cost.
