[0034] Specifically, during normal use of the valve, fluid enters the main body 1 through the water inlet 2, enters the first channel 4 and the second channel 5 through the partition of the partition 3, and is discharged through the water outlet 6. The valve block 7 controls the opening and closing of the first channel 4 and the second channel 5. When it is necessary to close both channels of the entire valve, the rotating rod 23 is rotated, the second bevel gear 20 is driven to rotate through the connection between the rotating rod 23 and the second bevel gear 20, the first bevel gear 19 is driven to rotate through the cooperation between the second bevel gear 20 and the first bevel gear 19, the sleeve 21 is driven to rotate, the threaded rod 17 is driven to rotate through the threaded connection between the sleeve 21 and the threaded rod 17, the closing block 9 is driven to descend, the water inlet 2 is closed through the cooperation between the closing block 9 and the partition 3 and the closing ring 12, so that fluid cannot enter the entire valve. After the water inlet 2 is closed by the closing block 9 and the closing ring 12, the entire pipeline is maintained. After the maintenance is completed, water or other low-cost fluid is added in the adding pipe 24. Since the diameter of the closing block 9 is smaller than the diameter of the channel in the main body 1, the liquid entering the main body 1 will enter the first channel 4 and the second channel 5, and will not reach the position of the water inlet 2. Thus, the water outlet 6 enters the external pipeline, and the repaired pipeline is maintained.

[0035] In summary, during use of the valve:

[0036] When the valve is normally used, fluid enters the main body 1 through the water inlet 2, enters the first channel 4 and the second channel 5 through the partition of the partition 3, and is discharged through the water outlet 6. The valve block 7 controls the opening and closing of the first channel 4 and the second channel 5.

[0037] When it is necessary to close both channels of the entire valve, the rotating rod 23 is rotated, the second bevel gear 20 is driven to rotate through the connection between the rotating rod 23 and the second bevel gear 20, the first bevel gear 19 is driven to rotate through the cooperation between the second bevel gear 20 and the first bevel gear 19, the sleeve 21 is driven to rotate, the threaded rod 17 is driven to rotate through the threaded connection between the sleeve 21 and the threaded rod 17, the closing block 9 is driven to descend, and the water inlet 2 is closed through the cooperation between the closing block 9 and the partition 3 and the closing ring 12, so that fluid cannot enter the entire valve.

[0038] When the water inlet 2 is closed by the closing block 9 and the closing ring 12, the entire pipeline is maintained. After the maintenance is completed, water or other low-cost fluid is added in the adding pipe 24. Since the diameter of the closing block 9 is smaller than the diameter of the channel in the main body 1, the liquid entering the main body 1 will enter the first channel 4 and the second channel 5, and will not reach the position of the water inlet 2. Thus, the water outlet 6 enters the external pipeline, and the repaired pipeline is maintained.

[0039] In all the above-mentioned solutions, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection or other known connection mode, which will not be described here. In the above, whenever there is a fixed connection, welding is preferred. Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
