The utility model is further configured to: the opening of the end of the guide pipe, which is far away from the valve body, is arranged downwards.
By adopting the technical scheme, after the guide pipe extends into the valve core, the fluid medium deposited in the valve core is discharged out of the valve body through the guide pipe under the action of gravity.
In conclusion, the utility model has the following beneficial effects:
according to the utility model, the guide pipe is arranged on the side surface of the valve body, and the opening of the guide pipe is arranged opposite to the bottom of the valve cavity, so that after the ball valve is closed, the guide pipe enables the valve cavity to be communicated with the outside of the valve body, and therefore, fluid media deposited in the valve cavity can be discharged to the outside of the valve body along the guide pipe, and the phenomenon that the conveyed fluid media are polluted due to the deterioration of the deposited media in the valve cavity for a long time when the ball valve is opened again is avoided.
The utility model fills gas into the valve core through the gas pipe and the gas injection device, can accelerate the discharge of the deposition medium from the valve core through the guide pipe, ensures the dry discharge of the medium in the valve cavity, and solves the problem that the fluid medium with higher viscosity flows slowly and is difficult to discharge.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a two-piece ball valve for preventing medium deposition, as shown in fig. 2, the two-piece ball valve comprises a valve body 1, the valve body 1 comprises a valve core 2, a valve rod 3 and a valve seat 4, flow channels 5 for flowing fluid medium are arranged on the left side and the right side of the valve core 2, the valve core 2 is provided with a valve cavity 6, as shown in fig. 1, a guide pipe 11 is arranged on the side surface of the valve body 1, the guide pipe 11 is communicated with the inside of the valve cavity 6 and is lower than the horizontal height of the bottom of the valve cavity 6, openings are arranged at the two ends of the guide pipe 11 and are used for discharging the medium deposited in the valve cavity 6 out of the valve body 1 through the guide pipe 11, as shown in fig. 3, an inclined surface 21 is arranged inside the valve core 2, the left side of the inclined surface 21 is higher than the right side, the guide pipe 11 is arranged at the bottom of the right side of the inclined surface 21, the fluid medium in the valve core 2 can flow into the guide pipe 21 under the action of gravity, one end of the guide pipe 11 far away from the valve body 1 is opened downwards, and then fluid medium passes through outside pipe 11 can discharge valve body 1, and the one end that pipe 11 kept away from valve body 1 still is provided with cap 112, and through threaded connection cooperation between cap 112 and the pipe 11, thereby the opening of being equipped with the sealing washer in the cap 112 to the pipe 11 outer end seals, avoids appearing the condition that medium leaks from pipe 11 when closing the ball valve temporarily.
The side surface of the valve body 1 is also provided with an air pipe 12, the installation height of the air pipe 12 is larger than that of the guide pipe 11 and is communicated with the interior of the valve core 2, the air pipe 12 is externally connected with an air injection device, so that the interior of the valve core 2 is inflated by the air injection device for fluid media with large viscosity and slow flow, and the fluid media can be rapidly discharged from the interior of the guide pipe 11 to the exterior of the valve body 1 under the action of pressure.
The working principle is as follows: the user drives the valve core 2 to rotate by rotating the valve rod 3 to close the ball valve, and because a small amount of fluid medium which does not pass through the flow passage 5 may be carried in the valve core 2, and the medium is deposited at the bottom of the valve cavity 6 for a long time and is easy to deteriorate, the deposited medium in the valve cavity 6 needs to be discharged, as shown in fig. 3 and 4, when the ball valve is in a closed state, the opening at the left end of the conduit 11 is abutted against the bottom of the right side of the inclined plane 21, the fluid medium deposited in the valve core 2 can enter the conduit 11 along the inclined plane 21 under the action of gravity and flow out to the outer side of the valve body 1 along the conduit 11, and then the user rotates and unscrews the cap cover 112, so that the fluid medium in the conduit 11 is discharged from the conduit 11, the user can collect or perform other operation treatments on the discharged medium, in order to avoid the medium conveyed in the flow passage 5 from having high viscosity, the medium deposited in the valve cavity 6 is difficult to naturally flow and discharge when the ball valve is in the closed state, a user can be externally connected with an air injection device through the air pipe 12, the air injection device fills air into the valve cavity 6 through the air pipe 12, and therefore fluid media accelerate to enter the guide pipe 11 under the action of air pressure and are discharged out of the valve body 1; when the user only closes the ball valve temporarily for a short time, the medium deposited in the valve cavity 6 does not need to be considered to be deteriorated, and under the condition, the user does not need to open the cap 112, and the cap 112 is matched with the sealing ring therein to plug the conduit 11, so that the medium in the valve cavity 6 is prevented from leaking out of the valve body 1.
