Abstract
The utility model relates to a combined type abrasive nozzle, comprising a water jet, a mixing chamber and an abrasive jet, which is characterized in that the abrasive jet is composed of a plurality of split units comprising a plurality of contraction sections with different contract angle Alpha and a plurality of linear sections with different lengths. Due to the combined type structure is adopted, the utility model has the advantages that a plurality of abrasive nozzles can be assembled using a small quantity of accessories, the cost is saved and the processing cycle is reduced and also the optimization of parameters are easy to be realized in experiments.
Description
Technical field
The utility model relates to a kind of combined type abrasive material shower nozzle, belongs to the water-jet technology field.
Background technology
The abrasive material shower nozzle is the key that forms abradant jet, and the quality of its design directly has influence on the performance of jet.Wearing and tearing to the abrasive material shower nozzle simultaneously also have a significant impact.In the compound abrasive jet of back, typical abrasive material shower nozzle mainly is made up of (operating) water nozzle, hybrid chamber and abrasive jet three parts, and the contraction section of abrasive jet and straightway are one.Aqueous medium is under the high pressure effect, form high-pressure water jet by (operating) water nozzle, and in hybrid chamber, produce certain vacuum, enter hybrid chamber with the suction abrasive material, abrasive material mixes with high-velocity flow turbulent fluctuation in hybrid chamber, assembles forming abrasive water-jet again by abrasive jet.Because the complexity that flows determines that these structural parameters are very difficult, should optimize parameter through a large amount of tests, to guarantee to give full play to the ability to work of jet according to factors such as the pressure of water jet, flow, abrasive material character, abrasive material consumptions in the practical application.That is to say for different operating modes and need multiple different abrasive material shower nozzle.And the common used material of the abrasive jet in the processing abrasive material shower nozzle is a tungsten carbide, and its price is expensive, be difficult to processing, and the process-cycle is long.
Summary of the invention
The purpose of this utility model is in order to optimize parameter, to guarantee to give full play to the ability to work of jet, to save cost, reduce the process-cycle, a kind of combined type abrasive material shower nozzle by contraction section and straightway split combination being provided.
The technical solution of the utility model: combined type abrasive material shower nozzle is become by (operating) water nozzle, hybrid chamber and abrasive jet, is characterized in, abrasive jet is combined by the contraction section of different angle of throat α and the straightway split of various different lengths.
Because the abrasive material shower nozzle has adopted knockdown structure to be combined into multiple abrasive material shower nozzle with a spot of part, has both saved cost, has reduced the process-cycle, is easy to realize in test Parameter Optimization again.
Description of drawings
Fig. 1 is a combined type abrasive material nozzle structure schematic diagram.
The specific embodiment
By shown in Figure 1, combined type abrasive material shower nozzle is made up of connecting tube 1, (operating) water nozzle 2, sprayer body 3, hybrid chamber 4, abrasive jet contraction section 5, abrasive jet straightway 6, locking nut 7 and quick abrasive material joint 8, be characterized in that abrasive jet can be that split combines by the abrasive jet contraction section 5 of various different angle of throat α and the abrasive jet straightway 6 of various different length L.For example: suppose to have the angle of throat of same diameter to be respectively α 1,2 contraction sections of α 2, and length is respectively the abrasive jet of 3 straightways of L1, L2, L3, according to the thinking of combination, we can obtain ading up to of built up nozzle: N=C2
1(C3
1+ C3
2+ C3
3)=2 (3+3+1)=14 still by traditional design, will process 14 abrasive jets.According to the utility model, only need 5 smallclothes of processing just can obtain 14 abrasive jets.This just provides cost savings and the process-cycle greatly.Nozzle interior WC because of operation under water, so apply mechanically stainless steel processing outward, had so both saved cost, was easy to centering again.
