Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of floating ball valve.
Background technique
Floating ball valve under the effect of pressure medium, produces certain displacement by spool thus be pressed on the sealing surface of outlet end to seal, usually the scope applied due to floating ball valve mostly is mesolow, the mounting type that valve rod adopts constrains the using scope of floating ball valve, if be applied in high-pressure medium, often there is the technical problem that valve rod is ejected, how to realize floating ball valve when original sealability is constant, the opening and closing that can be applied to high-pressure medium is technical problems to be solved in this application.
Model utility content
Main purpose of the present utility model is to provide a kind of reasonable in design, good seal performance, can be applicable to the floating ball valve of high-pressure medium.
For reaching above object, the technical solution adopted in the utility model is:
A kind of floating ball valve, comprise valve body, the valve gap sealing and be fastened is mated with valve body, and the spool be arranged between valve body and valve gap, described valve body top is provided with valve rod mounting hole, in described valve rod mounting hole, coupling is provided with valve rod, and valve rod mounting hole top is provided with sealing cover, described valve rod comprises upper valve rod and lower valve rod, described lower valve rod top is provided with cross connecting plate, the cross attachment hole corresponding with cross connecting plate is offered bottom described upper valve rod, described lower valve rod is provided with annular first positive stop lug boss, described annular first positive stop lug boss upper surface and lower valve rod outer wall are all fitted with valve rod mounting hole inwall, described upper valve rod is provided with annular second positive stop lug boss, between upper valve rod and valve rod mounting hole inwall, is provided with stuffing box packing, and described stuffing box packing coupling is pressed between sealing cover and the second positive stop lug boss.
The first described positive stop lug boss upper surface is tapered slope, is provided with seal ring between the first positive stop lug boss and corresponding valve rod mounting hole inwall.
Described valve rod mounting hole is step hole, seal washer has been installed with between the second described positive stop lug boss and the transition shoulder of valve rod mounting hole, the upper surface of the second described positive stop lug boss is tapered slope, and described stuffing box packing coupling laminating is pressed between sealing cover and the second positive stop lug boss.
Adopt technique scheme, acquired beneficial effect is:
The utility model reasonable in design, improve for traditional valve rod mounting type and stem structure, by stem structure is designed to made up, carry out pressurized by lower valve rod, upper valve rod completes the control to valve, thus substantially reduces the impact of the pressure medium suffered by sealing cover, substantially increase the sealability of whole valve, extend the working life of whole valve, by resolution of forces, improve application and the performance of floating ball valve.
Accompanying drawing explanation
