Specific implementation mode

It, below will be to required use in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment Attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is some embodiments of the utility model, for this For the those of ordinary skill of field, without creative efforts, others are can also be obtained according to these attached drawings Attached drawing.

Please refer to Fig. 2, Fig. 3 and Fig. 4, injector nozzle 10 include bracing members pipe 101, the first liner tetrafluoroethene pipe 102, The both ends of second liner tetrafluoroethene pipe 103, the bracing members pipe 101 are equipped with flange 1011, to be connect with extraneous pipeline, the One liner tetrafluoroethene pipe 102 is set in bracing members pipe 101, the first liner tetrafluoroethene pipe 102 and 101 interference of bracing members pipe Cooperation, and the both ends of the first liner tetrafluoroethene pipe 102 are equipped with the first flanging 1021, the first flanging 1021 and flange 1011 End face fit, to fix the first liner tetrafluoroethene pipe 102, the second liner tetrafluoroethene pipe 103 is set in the first liner In tetrafluoroethene pipe 102, and the second liner tetrafluoroethene pipe 103 and the first liner tetrafluoroethene pipe 102 are interference fitted, in second The length for serving as a contrast tetrafluoroethene pipe 103 is more than the length of the first liner tetrafluoroethene pipe 102, the second liner tetrafluoroethene pipe 103 One end is equipped with the second flanging 1031, and the end face of the second flanging 1031 and the first flanging 1021 fits, the second liner four The other end of fluoride tubes 103 is equipped with contraction mouth, to increase speed when working fluid outflow.

Existing injector nozzle 10 is generally unitary design, when being scrapped because of the reasons such as corrosion when nozzle, just needs Want integral replacing.Since nozzle will ensure mechanical strength and corrosion resistance, while wanting easy to process, therefore generally by mechanical strong It spends the inorganic material such as higher and corrosion resistant ceramics to be prepared, the cost of integral replacing is higher.The nozzle of the utility model is adopted With multilayered structure, the high mechanical strength of the bracing members pipe 101 of outer layer than inorganic material such as conventional ceramics.When nozzle needs replacing When, it is only necessary to replace the first liner tetrafluoroethene pipe 102 and the second liner tetrafluoroethene pipe 103, the cost of tetrafluoroethene pipe compared with It is low, therefore reduce replacement cost.

Further, the end face of two end flanges 1011 of the bracing members pipe 101 is equipped with and 1021 phase of the first flanging The groove of cooperation, so that the first flanging 1021 is embedded in the groove.

Since bracing members pipe 101 will be also fixedly connected with mixing chamber and water inlet line, the first flanging 1021 is embedded in recessed In slot, when pipeline can be made to connect, better seal effect is played.

Further, the second liner tetrafluoroethene pipe 103 includes fixed section 1032 and nozzle contraction section 1033, described Fixed section 1032 and nozzle contraction section 1033 are threadedly coupled, in order to adjust the second liner tetrafluoroethene pipe 103 outlet pipe Diameter, first flanging 1021 are located on fixed section 1032, and the contraction mouth of the second liner tetrafluoroethene pipe 103 is located at nozzle receipts In contracting section 1033.

In the actual production process, the mixed proportion of two kinds of liquid can be different, it is therefore desirable to which the nozzle of different bores imports Liquid, setting nozzle contraction section 1033 can facilitate the bore for adjusting nozzle, so as to adjust mixed proportion.

In a better embodiment, the preparation process of tetrafluoroethene pipe is as follows：First use poling machine or manually by pre- fixed length First liner tetrafluoroethene pipe 102 of degree is arranged into bracing members pipe 101, then by the two of the first liner tetrafluoroethene pipe 102 End is heated to glue, and flanging is made and is fitted on the end face of bracing members pipe 101；Later by the second liner tetrafluoroethene pipe 103 are arranged in the same way into the first liner tetrafluoroethene pipe 102.When needing replacing tetrafluoroethene pipe, with machinery Tetrafluoroethene pipe is extracted and is then replaced.

Above disclosures are merely preferred embodiments of the utility model, with this utility model cannot be limited certainly Interest field, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and according to this reality The equivalent variations made by novel claim, still fall within the scope of the utility model.
