As shown in fig. 1-3, a valve for cleaning acid mist treatment equipment pipelines and repairing leakage comprises a valve body 1, an intermediate shaft 2, a handle 3 and a valve core 5. The handle 3 is connected with the upper end of the middle shaft 2, the valve core 5 is connected with the lower end of the middle shaft 2, and the handle 3 is connected with the valve core 5 through the middle shaft 2; the valve core 5 is sleeved in the valve body 1. The valve body 1 is provided with an inlet 11, a first outlet 12, a second outlet 13, a positioning groove 14 and a through groove 15, the interior of the valve body 1 is hollow, and the inlet 11, the first outlet 12 and the second outlet 13 are communicated. The positioning slot 14 is located at the lower end of the through slot 15, and the positioning slot 14 is communicated with the through slot 15.

The valve core 5 is provided with a first through hole 51, a second through hole 52 and a positioning block 53, the positioning block 53 is positioned at the upper end of the valve core 5, the first through hole 51 and the second through hole 52 are positioned at the middle part of the valve core 5, and the lower end of the valve core 5 is solid. The first port 51 and the second port 52 are communicated with each other. The inlet 11, the first outlet 12, the second outlet 13, the first through opening 51, and the second through opening 52 have the same size. The positioning block 53 of the valve body 5 is rotatable in the through groove 15 of the valve body 1. The two ports of the valve core 5 are communicated with two of the inlet 11, the first outlet 12 and the second outlet 13. The second outlet 13 is a spare outlet. The valve body 1 is provided with a plurality of positioning grooves 14, the valve core 5 is provided with a plurality of positioning blocks 53, the positioning blocks 53 are uniformly distributed on the valve core 5, and the positioning grooves 14 are uniformly distributed on the valve body 1. The positioning block 53 is matched with the positioning groove 14, and the positioning block 53 can slide in the through groove 15. The valve body 1 is provided with a detection device 4, and an alarm is arranged inside the detection device 4. The detection device 4 is used for detecting whether the pipeline leaks or not, and when the detection device 4 detects that the pipeline leaks, an alarm inside the detection device 4 gives an alarm.

The utility model discloses at normal during operation, first port 51 communicates with each other with entry 11, and second port 52 communicates with each other with first export 12. When the detection device 4 detects that the pipeline leaks, an alarm inside the detection device 4 gives an alarm. An operator pulls the handle 3 downwards, the handle 3 drives the valve core 5 to move upwards through the intermediate shaft 2, the positioning block 53 also moves upwards, when the positioning block 53 moves upwards from the positioning groove 14 to the through groove 15, the handle 3 is rotated to the second through hole 52 to correspond to the position of the inlet 11, and when the second through hole 52 corresponds to the position of the inlet 11, the first through hole 51 corresponds to the position of the second outlet 13.

Similarly, when the handle 3 carries the valve core 5 to move downwards, the first through port 51 of the valve core 5 corresponds to the position of the inlet 11, and the second through port 52 corresponds to the position of the first outlet 12, the second outlet 13 corresponds to other positions of the valve core 5, and other positions of the valve core 5 are solid and can block the second outlet 13, so that the gas in the pipeline can only enter from the inlet 11 and flow out from the first outlet 12.

When the pipeline needs to be cleaned, an operator pulls the handle 3 downwards, the handle 3 drives the valve core 5 to move upwards through the middle shaft 2, the positioning block 53 also moves upwards, when the positioning block 53 moves upwards into the through groove 15 from the positioning groove 14, the handle 3 is rotated to enable the second through hole 52 to correspond to the position of the inlet 11, and when the second through hole 52 corresponds to the position of the inlet 11, the first through hole 51 corresponds to the position of the second outlet 13. When the handle 3 is pressed, the valve core 5 moves downwards, the positioning block 53 on the valve core 5 enters the positioning groove 14 from the through groove 15, at this time, the second port 52 is communicated with the inlet 11, the first port 51 is communicated with the second outlet 13, and the gas in the pipeline flows out from the second outlet 13. The first outlet 12 is blocked by the valve core 5, at the moment, a pipeline connected with the first outlet 12 is disassembled for cleaning, after the cleaning is finished, the gas outlet is switched to the first outlet 12, and the second outlet 13 is blocked by other parts of the valve core 5.

The utility model discloses set up two exports, one is the export of normal during operation, and one is reserve export. When the pipeline needs to be cleaned or leakage is repaired, the pipeline connected with the normal working outlet can be cleaned and repaired only by switching the outlet to the standby outlet. The utility model discloses when clean pipeline or restoration leak, can not stop production safety construction, reduced because of the loss that the off-line maintenance caused. The utility model discloses still set up detection device, carried out leak detection to the pipeline in real time, improved the security when using.
