Siphunculus, lower downpipe, upper adapting pipe, the main communicating pipe are horizontally disposed, and the lower downpipe is is vertically arranged, in the master
Pipe pressure adjusting means is provided between communicating pipe and lower downpipe, the pipe pressure adjusting means has heading joint head tube, the right angle
One end of junction block is connected with main communicating pipe by ring flange, and the other end is connected by ring flange with lower downpipe, described straight
The corner of corner connection head tube is provided with hollow spherical shell, and the inner chamber of the spherical shell is connected with the inner chamber of heading joint head tube
It is logical, birdsmouth flange is provided with the top of the spherical shell, surge pipe is installed on the birdsmouth flange, in the tune
Pressure pipe is provided with relief valve, and Isolation net cover, and institute are provided with the spherical shell and positioned at the porch of birdsmouth flange
State surge pipe and be provided with air pump device.
Further, it is contemplated that specific structure type, heading joint head tube described in the utility model are linked as with spherical shell
It is wholely set.
Further, in order to which more preferable using effect, the internal diameter of spherical shell described in the utility model are more than angle coupling
The internal diameter of pipe.
Further, in order to ensure the balance of external and internal pressure, the top of surge pipe described in the utility model and upper undertaking
The top of pipe is concordant.
Further, it is contemplated that noise reduction, the utility model apply in the inner surface of the heading joint head tube and spherical shell
It is covered with polyurethane foam.
The beneficial effects of the utility model are：The utility model is simple in construction, fully takes into account the principle of siphon drainage,
Set pipe to press adjusting means between main communicating pipe and lower downpipe, by the spherical shell on right-angle elbow pipe, force increase whole
The cavity of Negative Pressure Difference can be produced in individual pipe-line system in stage casing, greatly improves the flow that can be born, so as to improve pipeline blowdown
The performance of water, simultaneously, it is not necessary to booster pump individually is separately provided in every pipeline, can be with some pipelines being arranged side by side
Surge pipe is integrated into same air pump device, is pressurized, saves construction cost.
