Description

Technical Field

[0001] The invention relates to the technical field of ball valves, and in particular to a pharmaceutical ball valve without flow accumulation. Background Art

[0002] In the prior art, a ball valve is mainly composed of a valve body, a valve stem, a ball and a handle. There is only a cavity in the ball that passes through the water inlet and the water outlet, and a groove connected to the valve stem is opened on the top. The ball is located in the valve body, so a cavity is formed between the ball and the valve body, and between the valve stem and the ball. When the ball valve is opened, liquid will flow into the cavity from the water inlet, and when the ball valve is fully closed, the cavity will be isolated from the water inlet to form a closed space. The accumulated liquid in this space is prone to breed bacteria, and the liquid in the space needs to be cleaned, so there is room for improvement. Summary of the invention

[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a pharmaceutical non-accumulated flow ball valve, which has the advantage of clearing the accumulated liquid inside the ball.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pharmaceutical non-accumulated flow ball valve, comprising a valve body, the valve body comprising valve tubes distributed at both ends, the valve body being penetrated by a valve stem, one end of the valve stem being located in the valve body being fixedly connected to a sphere, the sphere being provided with a through groove running through the sphere, the bottom of the sphere being provided with a flow groove connected to the through groove, the valve body being provided with a first closed motor located in the flow groove, the first closed motor being connected to a first rotating shaft, the first rotating shaft being connected to a rotating plate, the rotating plate being fitted with an opening of the flow groove, a rubber ring being provided on the circumference of the rotating plate, the valve body being provided with a connecting block located on one side of the valve body, the connecting block being provided with a cleaning device for cleaning the inside of the sphere.

[0005] By adopting the above technical solution, the valve stem is rotated to drive the ball to rotate. When the ball rotates to the point where the opening direction of the through-groove is perpendicular to the length direction of the valve tube, the ball will play a role in blocking the valve tube. At this time, the first closed motor is started to drive the first rotating shaft to rotate. The first rotating shaft can drive the rotating plate to rotate. As the rotating plate rotates, the connecting area between the flow groove and the through-groove will continue to increase, and the liquid in the ball can flow out of the flow groove to avoid accumulation inside the ball. In addition, when the ball rotates to the isolation valve tube, the cleaning device can be started to clean the inside of the ball to keep the inside of the ball dry and tidy.

[0006] The present invention is further configured as follows: the cleaning device includes a driving cylinder located inside the connecting block, the driving cylinder is connected to the driving block, a driving motor is arranged inside the driving block, the driving motor is connected to a cleaning cylinder, a plurality of cleaning grooves are arranged on the side of the cleaning cylinder, a spring is fixedly connected to the bottom of the cleaning groove, the spring is connected to the cleaning block, and cleaning cotton is arranged on the side of the cleaning block away from the spring.

[0007] By adopting the above technical solution, when the sphere rotates to the opening of the through groove facing the inside of the cleaning device, the driving cylinder is started to drive the driving block to move toward the sphere, and the movement of the driving block can drive the driving motor to move and then drive the cleaning cylinder to move. In addition, during the movement of the driving motor, the driving motor is started to drive the cleaning cylinder to rotate around its own axis. When the cleaning cylinder moves to the inside of the sphere, as the cleaning cylinder rotates, the cleaning cylinder will drive the cleaning cotton to rotate and then allow the cleaning cotton to clean the side wall inside the sphere. When the cleaning cylinder is in the sphere, the cleaning block is acted upon by the spring and has a force to move outward, and cooperates with the inner wall of the sphere to enhance the cleaning effect of the cleaning cotton.

[0008] The present invention is further configured as follows: a protective sleeve is sleeved on the outer side of the cleaning cylinder, the protective sleeve can rotate around the axis of the cleaning cylinder, the protective sleeve is provided with a connecting groove that penetrates the protective sleeve, the protective sleeve can be rotated until the connecting groove is connected with the cleaning groove, the protective sleeve is provided with an inclined groove connected with the connecting groove, and the inclined surface of the inclined groove faces the cleaning cylinder.

[0009] By adopting the above technical solution, the protective cover is allowed to rotate around the axis of the cleaning cylinder. When the protective cover is rotated to the connection point and connected to the cleaning groove, a part of the cleaning cotton will be outside the protective cover under the action of the spring. In addition, when the cleaning cotton is not needed, the protective cover can be rotated. As the protective cover rotates, the groove wall of the inclined groove will squeeze the cleaning block, thereby moving the cleaning block toward the groove bottom of the cleaning groove. When the inclined groove and the connecting groove are not at the opening of the cleaning groove, the cleaning groove will be in a closed state, thereby preventing the cleaning cotton from being contaminated.

[0010] The present invention is further configured as follows: an L-shaped rod is connected to the side of the cleaning block, the L-shaped rod passes through the cleaning cylinder and a part of the L-shaped rod is outside the cleaning cylinder.

[0011] By adopting the above technical solution, the L-shaped rod is set so that the groove wall of the inclined groove squeezes the L-shaped rod to move the cleaning block toward the groove bottom of the cleaning groove, thereby reducing the wear on the cleaning cotton.

[0012] The present invention is further configured as follows: a flushing pipe is arranged above the sphere, a second rotating shaft is fixedly connected to the side of the flushing pipe, the second rotating shaft is connected to a second closed motor fixedly connected to the sphere, a water sprinkler is arranged inside the sphere above the flushing pipe, the water sprinkler is provided with a nozzle, a hose is arranged between the nozzle and the water sprinkler, and the nozzle is fixedly connected to the micro cylinder.

[0013] By adopting the above technical solution, when it is necessary to flush the inner wall of the sphere, the second closed motor can be started to drive the second rotating shaft to rotate. When the second rotating shaft rotates to the bottom of the nozzle, the micro cylinder can be started to drive the nozzle to move in the direction of the second rotating shaft. When the nozzle moves to the mouth of the flushing pipe, the nozzle can flow the water in the sprinkler into the sphere through the flushing pipe. The setting of the hose can prevent the nozzle from getting stuck.

[0014] The present invention is further configured as follows: a heating block is arranged in the cleaning cylinder.

[0015] By adopting the above technical solution, the heating block can make the cleaning cotton have a hygroscopic effect and can absorb moisture inside the sphere.

[0016] In summary, the present invention has the following beneficial effects:

[0017] Rotating the valve stem drives the ball to rotate. When the ball rotates to the point where the opening direction of the through-groove is perpendicular to the length direction of the valve tube, the ball will block the valve tube. At this time, starting the first closed motor drives the first rotating shaft to rotate. The first rotating shaft can drive the rotating plate to rotate. As the rotating plate rotates, the connecting area between the flow groove and the through-groove will continue to increase. The liquid in the ball can flow out of the flow groove to avoid accumulation inside the ball. In addition, when the ball rotates to the isolation valve tube, the cleaning device can be started to clean the ball to keep the ball dry and tidy. BRIEF DESCRIPTION OF THE DRAWINGS
