Problems solved by technology
[0004] However, when the steel ball rotates and closes, there will be liquid accumulation in the through hole on the steel ball. When the ball valve is used in food, pharmaceutical, drinking water and other industries, if the ball valve is closed for a long time, it will lead to liquid remaining in the steel ball. The effusion in the ball breeds bacteria, which will be mixed into the new liquid after the ball valve is opened to affect the product quality

Embodiment Construction
[0034] The present invention will be further described in detail below with reference to the accompanying drawings.
[0035] This embodiment discloses an anti-liquid accumulation ball valve, such as figure 1 As shown in the figure, it includes a valve body 1, a ball core 2 and a valve stem 3. The valve body 1 is formed with a spherical cavity (not shown in the figure), and the two ends of the valve body 1 are provided with a liquid inlet 11 that communicates with the spherical cavity and The liquid outlet 12 is respectively provided with a flange assembly for connecting the pipeline. The valve stem 3 is rotatably connected to the upper end of the valve body 1, and the end of the valve stem 3 exposed to the outside of the valve body 1 is provided with a handle 31 that is convenient for rotating operation; the ball core 2 is rotatably connected to the spherical cavity, and the upper edge of the ball core 2 is The radial direction of the valve stem 3 is provided with a fluid cha...

The present invention relates to the technical field of ball valves, and aims to provide an anti-flooding ball valve, which includes a valve body, a ball core and a valve stem. The lower end of the channel is provided with a drain hole that penetrates the ball core downwards, and the lower end of the valve body is provided with a drain chamber that communicates with the drain hole, and a seal that can move along the length direction of the valve stem is provided in the drain chamber. rod, and the end of the sealing rod close to the ball core is provided with a sealing plug capable of blocking the drain hole. When the control valve stem drives the ball core to rotate to block the fluid passage, the sealing rod is controlled to move downward along the axis of the valve stem, and the sealing plug is driven to open the drain hole, so that the residual liquid in the fluid passage can pass through the drain hole to the drain hole. Down into the discharge chamber, to prevent the liquid from staying in the fluid channel for a long time to cause bacteria to grow and deteriorate, and to prevent the deteriorated liquid from being mixed into the new liquid after the ball valve is opened to affect product quality.
Description
technical field [0001] The invention relates to the technical field of ball valves, in particular to an anti-liquid accumulation ball valve. Background technique [0002] Ball valve, the opening and closing part is a ball, which is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. [0003] At present, the Chinese patent document with the authorization announcement number CN203823117U in the prior art discloses a liquid-free ball valve, which includes a valve body, a steel ball, a valve stem assembly and a pair of ball pads; Through holes with the same water outlet; after the ball pads on both sides of the steel ball are compacted, the steel ball is completely wrapped, so that when the steel ball is opened or closed, the through hole of the steel ball is always in line with the side of the semicircular cavity of the ball pad Wall contact, so as to effectively prevent liquid from flowing into the gap ...
