Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a U type water seal, as shown in figure 1, including water seal body 1, the top of water seal body 1 is connected with the blow-off pipe 12 for discharge the inside air of gas piping or gas. The lower part of the bottom end of the water seal body 1 is connected with a communicating water tank 8 through a pipeline, a communicating valve 7 is arranged in a connecting pipeline between the water seal body 1 and the communicating water tank 8, a blow-down valve 9 is arranged at the bottom end of the communicating water tank 8, and impurities deposited in the water seal are discharged through the blow-down valve 9. The top end of the communicating water tank 8 is upwards connected with a communicating pipe 15, the top end of the communicating pipe 15 is not lower than the top end of the water seal body 1 and upwards fixed with a guide rail frame 14, and liquid level scales are longitudinally arranged on the upper edge of the guide rail frame 14. The buoy type liquid level meter 13 with the bottom end extending into the communicating pipe 15 is erected in the guide rail frame 14, the buoy type liquid level meter 13 is made of plastic, the structure comprises a cylindrical buoy body and a floating ball connected with the bottom end of the buoy body, and an indicating needle corresponding to liquid level scales is arranged on the side wall of the buoy body.

When the water seal device works, the communicating valve 7 is kept in an open state, the water seal body 1, the communicating water tank 8 and the communicating pipe 15 form a communicating device, and the liquid levels in the water seal body 1 and the communicating pipe 15 are changed synchronously. When the water level in the water seal body 1 is reduced due to abnormal reasons, the water level in the communicating pipe 15 is synchronously reduced, the buoy type liquid level meter 13 above the communicating pipe 15 is supported by the guide rail frame 14 and also reduced along with the water level, in the process, the floating ball is reduced along with the liquid level in the communicating pipe 15, the liquid level scale indicated by the indicating needle on the buoy body is the liquid level after the liquid level in the water seal body 1 is reduced, and the liquid level in the water seal body 1 can be directly read out through reading.
