Problems solved by technology
Since the gas medium and the liquid medium are frictionally atomized in the air outside the spraying equipment, the atomization is uneven, which leads to the inability to spray the rough slab evenly, so the spraying quality is poor

The invention provides a spraying valve and a spraying system. The spraying valve comprises a valve body, a flow adjusting rod, a liquid cap and an air cap; the valve body comprises a gas flow channel, a liquid flow channel and a driving cavity; the driving cavity penetrates the valve body; the liquid cap comprises a liquid cavity and through holes; the liquid cavity and the through holes both penetrate the liquid cap; the valve body is connected with the liquid cap, and the center line of the driving cavity and the center line of the liquid cavity are located on the same straight line; the flow adjusting rod is placed in the liquid cavity and the driving cavity; a gas and liquid mixing chamber is formed between an outlet of the air cap and the liquid cap; gas media are transmitted to thegas and liquid mixing chamber by the gas flow channel through the through holes; liquid media are transmitted to the liquid cavity by the liquid flow channel; and when the flow adjusting rod leaves the liquid cavity, the liquid media enter the gas and liquid mixing chamber and friction is generated between the liquid media and the gas media, and the liquid media are sprayed out of the outlet of the gas cap in an atomized state, so that an object to be wetted in a spraying manner can be wetted in a spraying manner. Thus, the scheme can improve the spraying wetting quality.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a spray valve and a spray system. Background technique [0002] Hot pressing of raw slabs is an important processing link in the production process of wood-based panels. Spray humidification is a key step in hot pressing of rough slabs. [0003] At present, the method generally adopted for spraying wet operation on rough slabs is: using wet spraying equipment to provide liquid medium and gas medium. The gas medium and the liquid medium are mixed and rubbed in the air outside the spraying equipment to form a spray, and then the rough slab is sprayed with the formed spray. Since the gas medium and the liquid medium are frictionally atomized in the air outside the spraying equipment, the atomization is uneven, which leads to the inability to uniformly spray the rough slab, so the quality of spraying is poor. Contents of the invention [0004] The invention provides a spray va...
