Abstract

The invention relates to the field of jet devices, in particular to an adjustable jet device. The adjustable jet device comprises a spray head, a long joint, a jet nozzle, a water absorption chamber welded piece and a mixing tube connected to the front end of the water absorption chamber welded piece through threads. The front end of the inner diameter of the spray head is sleeved with the jet nozzle. The outer diameter of the spray head is sleeved with the long joint. The rear portion of the water absorption chamber welded piece is connected to the front portion of the long joint through threads. The outer diameter of the rear portion of the long joint is slidably sleeved with a long joint pipe nut fixedly connected with the spray head. A front locking device and a rear locking device arearranged on the long joint pipe nut. The device is simple in structure and convenient to operate and can be adjusted at any time in a working state and continuously adjusted.

Description

technical field [0001] The invention relates to the field of jets, in particular to an adjustable jet. Background technique [0002] Ejectors designed using the Venturi principle have been widely used in agriculture, industry and other fields. However, due to the particularity of the structure of the ejector itself, most of the ejectors are non-adjustable, that is, once the design is completed, their working parameters have been solidified. Optimum performance cannot be guaranteed. [0003] There are many parameters that affect the working state of the ejector, but most of them are difficult to realize the adjustable function from the structure. At present, the adjustable ejector mainly adjusts its working state by adjusting the throat-mouth distance, and the adjustment of the throat-mouth distance is realized by adding or subtracting gaskets. [0004] Gasket-adjustable ejectors have the following disadvantages: [0005] It needs to be disassembled during adjustment, whic...
