The invention provides a duplex floating ball valve, which controls a valve by adopting double spheres in a mode of connecting two spheres in series, is provided with a third turntable, can operate the third turntable to rotate, drives a first turntable and a second turntable to rotate simultaneously, and realizes simultaneous adjustment of the two spheres.
Description
Technical Field
The invention relates to a valve, in particular to a duplex floating ball valve.
Background
The ball body of the ball valve is floating, and under the action of medium pressure, the ball body can generate certain displacement and is tightly pressed on the sealing surface of the outlet end, so that the outlet end is sealed. The ball valve has the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, closed sealing surface and spherical surface, difficult erosion by media, easy operation and maintenance, suitability for common working media such as water, solvent, acid, natural gas and the like, suitability for media with severe working conditions such as oxygen, hydrogen peroxide, methane, ethylene and the like, and wide application in various industries. The ball valve body can be integrated or combined. In the traditional pipeline, the connection form of a plurality of valves is complex, the leakage point in the system is more, the common floating ball valve adopts a ball body which is only convenient for one-way sealing, and when the leakage occurs to the single ball body, the sealing of the whole pipeline is not facilitated.
Disclosure of Invention
The invention aims to solve the technical problem of providing a duplex floating ball valve which adopts a double ball body to control a valve.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the utility model provides a ball valve is floated in pair, includes the valve body, is equipped with two spheroids in the valve body, is equipped with the disk seat at both ends about spheroidal, is equipped with first valve rod and second valve rod respectively in two spheroidal upper ends, and first valve rod, second valve rod and spheroid rotate with the valve body to be connected, the upper end of first valve rod is equipped with first carousel, is equipped with the second carousel on the second valve rod.
Preferably, a third turntable is arranged between the first turntable and the second turntable, and gears which are meshed with each other are arranged at the edges of the first turntable, the second turntable and the third turntable.
Preferably, the upper surface of the third rotating disc is also provided with a rotating handle.
Preferably, the lower end of the third rotating disc is provided with a rotating shaft, and the rotating shaft is inserted into the bearing sleeve.
Preferably, the first rotating disc and the second rotating disc are provided with rotating rods.
The invention provides a duplex floating ball valve, which controls a valve by adopting double spheres in a mode of connecting two spheres in series, is provided with a third turntable, can operate the third turntable to rotate, drives a first turntable and a second turntable to rotate simultaneously, and realizes simultaneous adjustment of the two spheres.
Drawings
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural diagram of the turntable of the present invention.
Detailed Description
As shown in fig. 1, a double-linkage floating ball valve comprises a valve body 1, two spheres 2 are arranged in the valve body 1, valve seats 3 are arranged at the left end and the right end of each sphere 2, a first valve rod 4 and a second valve rod 5 are respectively arranged at the upper ends of the two spheres 2, the first valve rod 4, the second valve rod 5 and the spheres 2 are rotatably connected with the valve body 1, a first rotary disc 6 is arranged at the upper end of the first valve rod 4, and a second rotary disc 7 is arranged on the second valve rod 5.
Preferably, as shown in fig. 2, a third rotating disk 8 is arranged between the first rotating disk 6 and the second rotating disk 7, and gears 9 engaged with each other are arranged at the edges of the first rotating disk 6, the second rotating disk 7 and the third rotating disk 8. The first turntable and the second turntable are driven to rotate by the third turntable.
Preferably, the upper surface of the third rotating disk 8 is also provided with a rotating handle 10. The third turntable is driven to rotate by rotating the handle.
Preferably, the lower end of the third rotating disk 8 is provided with a rotating shaft 11, and the rotating shaft 11 is inserted into a bearing sleeve 12. When the third rotating disc is not used, the third rotating disc is directly lifted upwards, and the rotating shaft is detached from the bearing sleeve.
Preferably, the first rotating disk 6 and the second rotating disk 7 are provided with rotating rods 13. The first turntable or the second turntable is operated to rotate alone by the rotating lever 13.
When the device is used, the two spheres can be controlled to rotate simultaneously by rotating the third turntable; when the first turntable or the second turntable needs to be operated independently to rotate, the third turntable is pulled out upwards, so that the third turntable is not in contact with the first turntable and the second turntable, and then the independent operation of the turntables can be realized by operating the rotating rod 13.
The above-described embodiments are merely preferred embodiments of the present invention, and should not be construed as limiting the present invention, and the scope of the present invention is defined by the claims, and equivalents including technical features described in the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
