AI Technical Summary
The existing distributors have shortcomings in terms of distribution effect and machining accuracy, especially the conical distributors have high requirements for machining accuracy and cannot eliminate the impact of flow velocity direction on distribution, poor distributive and non-detachable maintenance.
A new distributor is designed, adopting a copper tube and a base structure. The homogenizer is set in the diverter head and is fixed by a nut. The diverter head is equipped with multiple diverter channels and a main cavity of a sealed structure. The homogenizer and the diverter head form a distribution chamber. The fluid is directly sprayed into the homogenizer through the input hole for collision and mixing, and then enter the distributor through the through hole for distribution, reducing the impact of speed and weight on distribution and improving the uniformity of distribution.
Through this design, the uniformity of distribution is improved, the impact of speed and weight on distribution is reduced, and because the structure is removable, accessories can be replaced or repaired, improving the maintenance of the equipment.
