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 described in further detail below in conjunction with the accompanying drawings.
[0035] This embodiment discloses an anti-effusion ball valve, such as figure 1 As shown, including the valve body 1, the ball core 2 and the valve stem 3, a spherical cavity (not shown in the figure) is formed in the valve body 1, and the two ends of the valve body 1 are provided with a liquid inlet 11 and a The liquid outlet 12 is respectively provided with flange components for connecting pipes. 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 outside the valve body 1 is provided with a handle 31 for easy rotation operation; the ball core 2 is rotatably connected to the spherical cavity, and the upper edge of the ball core 2 The radial direction of the valve stem 3 is provided with a fluid channel 21 that can communicate with the liquid inlet 11 and the liquid outlet 12; The rotation of ...

The invention relates to the technical field of ball valves, and aims at providing a liquid accumulating preventing ball valve. A valve body, a ball core and a valve rod are included. The ball core isprovided with a fluid channel capable of communicating with a liquid inlet and a liquid outlet. The lower end of the fluid channel is provided with a liquid discharging hole downwards penetrating through the ball core. A liquid discharging cavity communicating with the liquid discharging hole is formed in the lower end of the valve body. A seal rod capable of moving in the length direction of thevalve rod is arranged in the liquid discharging cavity. The end, close to the ball core, of the seal rod is provided with a seal plug capable of blocking the liquid discharging hole. After the valverod is controlled to drive the ball core to rotate and partition the fluid channel, the seal rod is controlled to downwards move along the axis line of the valve rod, the seal plug is driven to open the liquid discharging hole, accordingly, liquid left in the fluid channel can downwards enter the liquid discharging cavity through the liquid discharging hole, the situation that liquid stays in thefluid channel for a long term, consequently, bacteria are bred, and deterioration happens is avoided, and the situation that after the ball valve is opened, the deterioration liquid is mixed in new liquid, and the product quality is influenced is prevented.
Description
technical field [0001] The invention relates to the technical field of ball valves, in particular to an anti-fluid 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 adjustment and control. [0003] At present, the Chinese patent document with the authorized announcement number CN203823117U in the prior art discloses a ball valve without effusion, which includes a valve body, a steel ball, a valve stem assembly and a pair of ball pads; The same through hole for the water outlet; the ball pads on both sides of the steel ball will completely wrap the steel ball after the ball is closed, 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, thereby effectively preventing liquid from flowing into the gap betw...
