Problems solved by technology

[0002] The currently used mechanical atomizing nozzle mainly adjusts its output by changing the pressure of the source medium. Since its output is proportional to the 1 / 2 power of the pressure, when the pressure of the source medium is lower than 1 / 2 of its rated pressure , the atomization effect of the atomizing nozzle will become worse. At this time, the adjustment ratio of the mechanical atomizing nozzle is only about: (1 / 2)^(1 / 2)≈1.4, which cannot meet the requirements of the on-site working conditions

Abstract

The invention provides a mechanical atomization nozzle with a wide turndown ratio. The mechanical atomization nozzle comprises a connection sleeve and a multilayer tangential rotational flow groove type rotational flow atomization sheet which is arranged inside the connection sleeve, wherein an adjustment needle is arranged inside the multilayer tangential rotational flow groove type rotational flow atomization sheet; the outer end of the multilayer tangential rotational flow groove type rotational flow atomization sheet is provided with a large nut used for fastening the multilayer tangential rotational flow groove type rotational flow atomization sheet onto the connection sleeve; a plurality of tangential rotational flow grooves are arranged on the outer circumference wall at the front part, which is matched with the adjustment needle, of the multilayer tangential rotational flow groove type rotational flow atomization sheet; and the front end of the multilayer tangential rotational flow groove type rotational flow atomization sheet is provided with an atomization sheet center jet orifice with a horn-shaped external part. By changing the position of the adjustment needle in the multilayer tangential rotational flow groove type rotational flow atomization sheet, the areas of the tangential rotational flow grooves and the atomization sheet center jet orifice are covered so that the output of a source medium is changed under the condition that the pressure of the source medium is not changed. The mechanical atomization nozzle provided by the invention has the advantages of simple structure, convenience in use, less investment and reliability in operation.

Description

technical field [0001] The invention relates to an atomizing spray head, especially a mechanical atomizing spray head suitable for a wide adjustment ratio when the pressure of the source medium is lower than 1 / 2 of its rated pressure. Background technique [0002] The currently used mechanical atomizing nozzle mainly adjusts its output by changing the pressure of the source medium. Since its output is proportional to the 1 / 2 power of the pressure, when the pressure of the source medium is lower than 1 / 2 of its rated pressure , the atomization effect of the atomizing nozzle will become worse. At this time, the adjustment ratio of the mechanical atomizing nozzle is only about: (1 / 2)^(1 / 2)≈1.4, which cannot meet the requirements of the on-site working conditions. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a mechanical atomizing nozzle with simple structure, convenient adjustment and goo...
