A kind of injector mixing chamber includes bracing members shell, liner tetrafluoroethene anti-corrosion layer, the bracing members shell with Liner tetrafluoroethene anti-corrosion layer fits, and the front end of the bracing members shell is equipped with circular mixture export, is expanded with connecting Room is dissipated, the rear end of bracing members shell is equipped with circular nozzle interface, to connect nozzle, the center of circle of mixture export and nozzle interface On the same axis, the side wall of bracing members shell be equipped with driving fluid pipeline so that driving fluid by driving fluid pipeline into Enter mixing chamber, mixture export, nozzle interface, driving fluid pipeline port at be equipped with flange, to be fixed with extraneous pipeline The port of connection, the liner tetrafluoroethene anti-corrosion layer is equipped with flanging, the end face of flanging and the flange of bracing members shell Fitting.

Preferably, the end face of the flange is equipped with annular recess, annular recess and liner tetrafluoroethene anti-corrosion layer Flanging matches, so that in the flanging insertion annular recess of liner tetrafluoroethene anti-corrosion layer.

Preferably, the rear end of the bracing members shell is cylindric, and driving fluid pipeline is arranged after bracing members shell On the side wall at end, and the axis of driving fluid pipeline is vertical with the axis of bracing members shell, and the front end of bracing members shell is round platform It shape and shrinks along the direction of mixture export, with the speed for collecting fluid and when increasing fluid outflow, sets on bracing members shell There is handle, in order to carry.

Advantageous effect：The injector mixing chamber of the utility model includes bracing members shell, liner tetrafluoroethene anti-corrosion layer, Bracing members shell has good mechanical strength, lasts a long time simultaneously；Liner tetrafluoroethene anti-corrosion layer has good corrosion resistant Corrosion, while the skin-friction coefficient of liner tetrafluoroethene anti-corrosion layer is low, therefore when by fluid impact, the degree of wear It is relatively low, and replacement cost is relatively low.

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.

Fig. 2, Fig. 3 and Fig. 4 are please referred to, injector mixing chamber 10 is corrosion-resistant including bracing members shell 101, liner tetrafluoroethene Layer 102, the bracing members shell 101 fits with liner tetrafluoroethene anti-corrosion layer 102, before the bracing members shell 101 End is equipped with circular mixture export 1011, and to connect diffuser casing 30, the rear end of bracing members shell 101 connects equipped with circular nozzle Mouthfuls 1012, to connect nozzle 30, the center of circle of mixture export 1011 and nozzle interface 1012 on the same axis, bracing members shell 101 side wall is equipped with driving fluid pipeline 1013, so that driving fluid enters mixing chamber 10 by driving fluid pipeline 1013, mixes Liquid is closed to export equipped with flange 1014 at the port of 1011, nozzle interface 1012, driving fluid pipeline 1013, with the pipeline with the external world It is fixedly connected, the port of the liner tetrafluoroethene anti-corrosion layer 102 is equipped with flanging 1021, flanging 1021 and bracing members shell The end face of the flange 1014 of body 101 is bonded.

Integrally formed injector mixing chamber 10 generally when being scrapped by external world's collision or internal corrode, is typically only capable to It is enough that injector is integrally unloaded to replacement.Since integrally formed injector mixing chamber 10 will consider machinery in actual use The problems such as intensity, service life, therefore side wall is thicker.But due to injector also can corrosive substance such as mix acid liquor, this will It asks injector material that there is stronger corrosion resistance, therefore the metal materials such as steel cannot be used to be made.Common ceramics or quartz The cost of manufacture of pipe inspection device is higher, so being also required to higher cost when replacing.The injector of the utility model includes steel Supporing shell 101 and liner tetrafluoroethene anti-corrosion layer 102, bracing members shell 101 have good mechanical strength, impact resistant, Long lifespan.Liner tetrafluoroethene anti-corrosion layer 102 is cheap, the low good corrosion resistance of replacement cost.Its surface is relatively smooth, institute When being in contact with it that area is smaller while fluid passes through with corrosive liquid, the erosion effect being subject to is also smaller, and service life is longer.

Further, the end face of the flange 1014 is equipped with annular recess, annular recess and liner tetrafluoroethene corrosion resistant The flanging 1021 of erosion layer 102 matches, so that the flanging 1021 of liner tetrafluoroethene anti-corrosion layer 102 is embedded in annular recess In.

Further, the rear end of the bracing members shell 101 is cylindric, and driving fluid pipeline 1013 is arranged in bracing members On the side wall of the rear end of shell 101, and the axis of driving fluid pipeline 1013 is vertical with the axis of bracing members shell 101, steel branch The front end for supportting shell 101 is round table-like and is shunk along the direction of mixture export 1011, to collect fluid and increase fluid stream Speed when going out, bracing members shell 101 is equipped with handle, in order to carry.

In a better embodiment, the liner tetrafluoroethene anti-corrosion layer 102 of injector mixing chamber 10 passes through sintering process It is prepared.

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.
