The valve body includes the left valve barrel 81 and right valve barrel 82 being detachably connected, and the first spheroid 91 is provided with the left valve barrel 81, described
Is provided with the second spheroid 92 in right valve barrel, in addition to is used for the left valve barrel and the fastening assembly 7 that there is valve body to connect together.Make
To be preferred, left valve barrel and right valve barrel can also be connected by screw, and it is right to be provided with adpting flange on left valve barrel and on right valve barrel
After be connected by screw, sealing ring 98 can be provided with the opposite face of left valve barrel and right valve barrel here strengthen sealing.
In the present embodiment, as illustrated, the left valve barrel peripheral outer wall is provided with the first flange 911, the right valve barrel
Upper to be correspondingly provided with the second flange 912 with first flange, the fastening assembly includes front band 71, the lower catch hoop being correspondingly arranged
72 and for connecting the fastening stud 73 of the front band and lower catch hoop, it is provided with and is used for and first flange in the front band
The first buckling groove 711 that upper end and the first flange upper end load, be provided with the lower catch hoop be used for the first flange lower end and
The second buckling groove 721 that second flange lower end loads.As preferable, the first flange and the second flange mirror image are set, and two
Individual flange closes up that to form cross section be trapezoidal structure, and the cross section of corresponding first buckling groove and the second buckling groove is also to be trapezoidal
Structure, more preferable clamping effect can be reached.
In the present embodiment, as illustrated, being additionally provided with fixed plate 6 on the valve body, it is logical that the fixed plate is provided with first
Hole 61, in addition to the action bars being threadedly coupled with the first through hole, the action bars bottom are correspondingly arranged with the front band,
The fastening stud is through the lower catch hoop, front band and is threadedly coupled with the fixed plate, the fastening stud middle-end screw thread
Fixed column 63 is connected with, the first elastic component 631, the fixation are provided between the fixed column upper surface and the front band bottom
The second elastic component is provided between post lower surface and the lower catch hoop upper surface.When needing to fix, rotating operation bar（As
It is preferred that action bars is provided with handwheel）, action bars pushes front band.Front band is driven to push on the upper flange of card column first and second
Flange, and then lower catch hoop is compressed, it is simple in construction, it is easy to operate.
In the present embodiment, as illustrated, first spheroid be provided with synchronous axial system the first valve rod 2, described first
Valve rod 2 is provided with the first spacing ring 21 of synchronous axial system；Second spheroid is provided with the second valve rod 3 of synchronous axial system, described
Second valve rod is provided with the second spacing ring 31 of synchronous axial system, and the peripheral outer wall of the first spacing ring 21 includes the first arc sections
211 and first escape groove 212, the peripheral outer wall of the second spacing ring 31 include the second arc sections 311 and the second escape groove 312,
