[0002] A ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. Three-way ball valves are available in T-type and L-type. The T-type can connect three orthogonal pipes to each other and cut off the third channel, thereby playing the role of diversion and confluence.

[0003] For example, the utility model: "A T-type three-way ball valve with sewage discharge", the announcement number is: "CN206943486U", this patent makes full use of the special structure of the valve core, so that the three-way ball valve can control and adjust the flow area and flow distribution of the valve body outlet flow channel by rotating to change the opening angle of the ball body without causing a significant change in the flow area of ​​the inlet flow channel of the three-way ball valve due to the obstruction of the ball body. However, during use, this patent requires a sewage discharge ball valve to be set at the bottom of the three-way ball valve, and its structure is complicated, and the sewage discharge process is relatively inconvenient to operate. Therefore, the present utility model provides a T-type three-way ball valve with sewage discharge to solve the above problem. Utility Model Content

When in use, the sealing rubber plug 3 is inserted into the drain pipe 4, and the sealing cover plate 2 is tightly fitted with the bottom of the drain pipe 4, so that the drain pipe 4 can be sealed by the sealing rubber plug 3.

[0025] Furthermore, a telescopic spring 11 is installed on the top of the inner rod 8, and the end of the telescopic spring 11 away from the inner rod 8 is connected to the mounting sleeve 6. The elastic action of the telescopic spring 11 pulls the inner rod 8 upward, so that the sealing rubber plug 3 can be tightly installed inside the sewage pipe 4.

[0026] Furthermore, a mounting hole 15 is provided at the top of the mounting sleeve 6 away from the end of the sewage pipe 4, and a fixing rod 14 is installed inside the mounting hole 15. The fixing rod 14 is inserted into the fixing hole 16, and the inner rod 8 is limited by the fixing rod 14 to prevent the inner rod 8 from continuing to move, so that the inner rod 8 can be firmly fixed, thereby preventing the sealing rubber plug 3 from moving inside the sewage pipe 4, and the sealing rubber plug 3 can be firmly fixed inside the sewage pipe 4.

[0027] Furthermore, a connecting plate 13 is installed at the end of the fixed rod 14 away from the mounting sleeve 6, and a fixing spring 12 is installed at the bottom of the connecting plate 13 close to the mounting sleeve 6. The end of the fixing spring 12 away from the connecting plate 13 is connected to the mounting sleeve 6. The elastic action of the fixing spring 12 causes it to pull the connecting plate 13 to move, and the connecting plate 13 drives the fixing rod 14 to move, so that the fixing rod 14 can be inserted into the fixing socket 16.

[0029] Furthermore, an anti-rust layer is provided on the outer side of the fixing spring 12 , which is beneficial to prolonging the service life of the fixing spring 12 .

[0030] Working principle:

[0031] When in use, the sealing rubber plug 3 is inserted into the sewage pipe 4, and the sealing cover plate 2 is tightly fitted with the bottom of the sewage pipe 4, so that the sewage pipe 4 can be sealed by the sealing rubber plug 3;

[0032] At this time, the elastic action of the telescopic spring 11 causes the U-shaped plate 7 to move upward through the inner rod 8, so that the sealing rubber plug 3 can be tightly installed inside the sewage pipe 4;

[0033] When the fixed socket 16 moves to a position facing the fixed plug rod 14, the elastic action of the fixed spring 12 causes it to pull the connecting plate 13 to move, and the connecting plate 13 drives the fixed plug rod 14 to move, so that the fixed plug rod 14 can be inserted into the fixed socket 16. The fixed plug rod 14 limits the inner rod 8, which can prevent the inner rod 8 from moving further, and thus the inner rod 8 can be firmly fixed, thereby preventing the sealing rubber plug 3 from moving inside the sewage pipe 4, and the sealing rubber plug 3 can be firmly fixed inside the sewage pipe 4;

[0034] When sewage needs to be discharged, the staff can first pull the connecting plate 13, and the connecting plate 13 drives the fixed plug rod 14 to move, and the fixed plug rod 14 can be taken out from the fixed plug hole 16, so that the fixed plug rod 14 can release the limit of the inner rod 8, so that the inner rod 8 can move;

[0035] Then the staff can pull the U-shaped plate 7 downward to remove the sealing rubber plug 3 from the inside of the sewage pipe 4, so that the sewage inside the three-way ball valve body 1 can be discharged through the sewage pipe 4;

[0036] The staff then rotates the rotating rod 17, and the rotating rod 17 drives the sealing cover plate 2 to rotate through the connecting rod 5, so that the sealing cover plate 2 is perpendicular to the valve body 1 of the three-way ball valve, and the sealing rubber plug 3 can be removed from under the sewage pipe 4 to prevent the sealing rubber plug 3 from blocking the sewage pipe 4 and affecting the sewage discharge process.
