Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] see Figure 1-4 , a quick opening and closing ball valve structure, including an upper valve body 1, the upper valve body 1 is fixedly connected with a first bearing 2, and the inner ring of the first bearing 2 is fixedly connected with a valve stem 3, and the bottom of the valve stem 3 is fixedly connected with a collar 5. The purpose of setting the collar 5 is to reduce the gap between the bottom of the valve stem 3 and the upper valve body 1. The out...

The invention relates to the technical field of ball valve devices, and discloses a quick opening and closing ball valve structure which comprises an upper valve body, wherein the upper valve body is fixedly connected with a first bearing, an inner ring of the first bearing is fixedly connected with a valve rod, a shaft ring is fixedly connected to the bottom of the valve rod, a first connecting rod is fixedly connected to the bottom of the shaft ring, a ball body is fixedly connected to the other end of the first connecting rod, and the bottom of the ball body is connected with a lower valve body through a second connecting rod. According to the quick opening and closing ball valve structure, by arranging a third bearing, the ball valve can be opened and closed more quickly, and more labor is saved; by arranging a first flange plate, a second flange plate and the upper valve body can be connected more firmly; and the second flange plate is arranged, so that the third bearing is convenient to mount, and the rotating shaft is not easily separated from the ball valve; the shaft ring is arranged to reduce a gap between the bottom of the valve rod and the upper valve body; and by arranging a sealing ring, water flow is prevented from flowing out of space between the valve rod and the upper valve body.
Description
technical field [0001] The invention relates to the technical field of ball valve devices, in particular to a fast opening and closing ball valve structure. Background technique [0002] Fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines, its strength, safety, and resistance to harsh environments have been specially considered in design, and it is suitable for various corrosive and non-corrosive media , The fixed ball valve has small torque, small seat deformation, stable sealing performance and long service life, and is suitable for high pressure and large diameter occasions. [0003] At present, many ball valves on the market start and close the ball valve through the turntable, which often needs to be turned several times to start and close, which is relatively slow and requires a certain amount of force, which is easy to make people tired and is not conducive to subsequent work. Con...
