Abstract
The utility model discloses a kind of floating ball valves for preventing screw loosening, comprising: valve rod, stop screw and handle set, the handle set is equipped with the container extended along the vertical direction, the valve rod is inserted in container along the vertical direction, the handle set is equipped with horizontally extending and penetrates through to the screw slots of container, and the stop screw is installed in screw slots, in which: in the vertical direction, the valve rod includes two planes and two arc surfaces, and the stop screw is resisted against in a plane.The valve rod can prevent from skidding with plane contact, and after switching repeatedly, stop screw will not loosen, and ensure that valve normal switch.
Description
Technical field
The utility model is related in a kind of floating ball valve more particularly to a kind of floating ball valve for preventing screw loosening.
Background technique
Floating ball valve structure is simple, good seal performance, is widely used in the control system of the industries such as petroleum, natural gas.
The prior art please refers to Fig. 1 and Fig. 2, and the stop screw position of existing floating ball valve handle set is unreasonable, by opening for a long time
The phenomenon that loosening behind pass it is easy to appear handle set, influences the position of the switch of valve, causes valve to close not in place, and interior leakage occurs.
In view of the drawbacks described above of the prior art, it is really necessary to design a kind of floating ball valve for preventing screw loosening.
Utility model content
Technical problem to be solved by the utility model is to provide a kind of floating ball valves, can prevent screw loosening.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of floating ball valve preventing screw loosening comprising: valve rod, stop screw and handle set, the handle set
Equipped with the container extended along the vertical direction, the valve rod is inserted in container along the vertical direction, and the handle set is equipped with edge
Horizontal direction extends and penetrates through to the screw slots of container, and the stop screw is installed in screw slots, in which: in vertical direction
On, the valve rod includes two planes and two arc surfaces, and the stop screw is resisted against in a plane.
Compared with prior art, the utility model has the beneficial effect that the valve rod and plane contact (face contact) can be to prevent
It only skids, after switching repeatedly, stop screw will not loosen, and ensure that valve normal switch.
Further improvement of the utility model is as follows:
Further, the cross section of the valve rod is in horse race road shape.
Further, the handle set includes perforative through slot in the horizontal direction, the floating for preventing screw loosening
Ball valve includes the handle being housed in through slot, and the handle is perpendicular to valve rod.
Further, the floating ball valve for preventing screw loosening further includes being mounted on above handle set and against to handle
Lock-screw.
Further, the handle extends beyond handle set.
Detailed description of the invention
Fig. 1 to Fig. 2 is the schematic diagram of the prior art.
Fig. 3 to Fig. 4 is the schematic diagram of the utility model.
Specific embodiment
The utility model is further explained with reference to the accompanying drawings and examples.
As shown in Figure 3 and Figure 4, a kind of floating ball valve for preventing screw loosening to meet the utility model comprising: valve
Bar 1, stop screw 2 and handle set 3.
The handle set 3 is equipped with the container 31 extended along the vertical direction, and the valve rod 1 is inserted in receiving along the vertical direction
In slot 31, the handle set 3 is equipped with horizontally extending and penetrates through to the screw slots 32 of container, and the stop screw 2 is pacified
Loaded in screw slots 32.In the vertical direction, the valve rod 1 includes two planes 11 and two arc surfaces 12, and the stop screw 2 supports
It is against in a plane 11.
The cross section of the valve rod 1 is in horse race road shape.The handle set 3 includes perforative through slot 33 in the horizontal direction.
The floating ball valve for preventing screw loosening includes the handle 4 being housed in through slot 33, is used for manual switch valve, described
Handle 4 is perpendicular to valve rod 1.The floating ball valve for preventing screw loosening further includes being mounted on the top of handle set 3 and against to hand
The lock-screw 5 of handle 4.The handle 4 extends beyond handle set 3.
Compared with prior art, the utility model have the beneficial effect that the valve rod 1 contacts (face contact) with plane 11 can be with
It prevents from skidding, after switching repeatedly, stop screw 2 will not loosen, and ensure that valve normal switch.
The utility model is not limited to above-mentioned specific embodiment, and those skilled in the art visualize from above-mentioned
Hair, without creative labor, made various transformation are all fallen within the protection scope of the utility model.
