Description

Slow flow nozzle and pouring machine Technical Field The invention relates to the technical field of liquid pouring, in particular to a slow-flow nozzle and a pouring machine. Background At present, in industrial production such as petroleum transportation, liquid chemical raw material transfer, beverage filling, in order to guarantee the security of pouring precision and filling operation, the liquid level state needs to be kept steady in the pouring process, in order to realize this purpose, simpler mode is near extending the nozzle to the liquid storage tank bottom for the liquid level is located the liquid outlet top in the pouring process, however, this kind of mode makes the surface of nozzle contact with liquid, the easy liquid that causes the filling pollutes, simultaneously, the nozzle also receives the corruption easily, thereby cause certain influence to the structure and the life of nozzle, or also can set up adjusting device, adopt intelligent control's mode to change the outflow speed, but the structure is more complicated, and the cost is higher. Disclosure of Invention The invention provides a slow flow nozzle and a perfusion machine, which are used for solving the problems that in the prior art, in order to keep the liquid level stable in the perfusion process, the nozzle needs to be extended to the vicinity of the bottom of a liquid storage tank for perfusion, or an adjusting device with a complex structure needs to be arranged for auxiliary perfusion. In a first aspect, an embodiment of the present invention provides a slow flow nozzle, including a nozzle housing, a diverter, and an outflow cover; the nozzle housing comprises a first part and a second part, wherein the first part is of a cylindrical structure, the second part is connected with the first part, and the cross section area of the second part is gradually increased along the flowing direction of liquid; The flow divider and the outflow cover are sequentially arranged on the second part along the flowing direction of liquid, the flow divider comprises a flow dividing chassis, a conical part is arranged on one side of the flow dividing chassis, which faces the first part, the top end of the conical part points to the first part, a plurality of flow dividing holes are further formed in the flow dividing chassis, the flow dividing holes are formed around the conical part, and a plurality of outflow holes are formed in the outflow cover.
