Compared with the prior art, the utility model has the beneficial effects that:

1. the drainage speed is greatly increased by using the plurality of branch pipes, and the drainage efficiency is improved; and the plurality of water discharge pipes reduce the area of water pressure acting in the pipes, effectively avoid branch pipes from being broken due to overlarge pressure in the cooling pipeline in the water discharge process, further reduce nuclear pollution and greatly improve the water discharge safety.

2. The foreign matter in the pipeline can be completely discharged through the branch pipe by utilizing the function of the flow guide part, the problem that the drainage speed is reduced due to the blockage of the pipeline is effectively avoided, and the influence on the drainage speed caused by the formation of the throat diameter of upstream and downstream drainage is also avoided.

3. Utilize the buffering subassembly, need be when the valve is closed suddenly for the drainage for the outer tube drives flange compression spring in, can effectively alleviate the water hammer and strike and then reduce rivers and to the effect of pipeline, effectively avoided because the water hammer dashes the pipeline damage that arouses.

4. Utilize the valve, can control the velocity of water and open and stop at drainage in-process, and then control drainage speed according to the drainage demand in order to satisfy the maintenance needs, and accessible valve stops the drainage when the water receiving container of low reaches is full, makes things convenient for in the change water receiving container.
