Technical field

A kind of material surface technical field of modification of the present invention, and in particular to the injection apparatus of mixing chamber before liquid is solid.

Background technique

It is mechanical during one's term of military service, the fatigue life of key components and parts directly affects mechanical service life, and fatigue failure is The principal mode of key components and parts failure, the common method for improving key components and parts fatigue life mainly have shot-peening, extruding, rolling Pressure, the surface layers method of modifying such as jet strengthened, as a result, components surface layer introduce residual compressive stress, change microscopic structure layer, Rigidity layer, to improve fatigue life.

It is jet strengthened to strengthen comprising pure water jets reinforcing, abradant jet；It includes rear compound abrasive jet stream that abradant jet, which is strengthened, Strengthen and the Premixed Abrasive Water Jet is strengthened, compared with pure water jets are strengthened, rear compound abrasive is jet strengthened, the Premixed Abrasive Water Jet Strengthen have jet pressure is low, capacity usage ratio is high, controllability is good, it is more and more concerned.

Currently, the switch control of water in preceding mixing water jet system, the switch control of pellet are separated from each other, and lead to the water-bindered pill Between mixed proportion control can not accurately realize, cause the pellet on jet area to be unevenly distributed, it is modified to influence surface layer Effect；In addition, water and the mixed liquid of pellet, will form jet stream by Pipeline transport to spray head, pipeline inner wall is in mixed liquor Under the erosion of body, it can wear rapidly and to shut down replacement, influence the normal use of jet apparatus；Therefore, it is necessary to design A kind of novel injection apparatus, to realize that accurately controlling for water-bindered pill mixing is integrated with fluidic vectoring thrust.

Summary of the invention

The purpose of the invention is to overcome the deficiencies in the prior art, and the water-bindered pill can precisely be adjusted by providing one kind Mixed proportion and the injection apparatus for realizing the solid preceding mixing chamber of the integrated liquid of mixing jetting.

Purpose of the present invention implementation is as follows: the injection apparatus of mixing chamber before a kind of liquid is solid, it include cylinder body, upper cover and Lower cover, the cylinder body are provided centrally with mixing chamber, and the upper cap upper surface is provided centrally with threaded connection hole A, institute Upper cover below threaded connection hole A stated is connected with upper cover chamber, and the position of the intracavitary close bottom end of the upper cover is provided with valve Core guide sleeve, the interior spool for being provided with T-type structure slided of the spool guide sleeve, the top of the intracavitary spool of the upper cover It is provided with adjustment sheet, seals and is slidably connected between the top of the spool and the side wall of upper cover chamber, the intracavitary valve of the upper cover It is provided with air cavity on the outside of spool between the top and spool guide sleeve of core, on the side of the upper cover position corresponding to air cavity It installs and is equipped with gas vent, the upper side for covering upper cover chamber is provided with channel A, connects above the upper cover upper channel A It is connected to threaded connection hole B, threaded connection hole C is provided on the side wall of the cylinder body, the inner end of the threaded connection hole C connects It is connected to channel B, is connected with damping block between the threaded connection hole C and channel B, the lower cover is provided centrally with channel C, the top of the channel C are connected with wear-resisting seat, and the wear-resisting seat is corresponding with the lower end of spool, the channel C It is provided with the connecting hole A being connected to the end of channel B on side wall, is provided with threaded connection hole D, institute on the side wall of the lower cover The inner end of the threaded connection hole D stated is connected by connecting hole B with the side wall of channel C, and the end of the lower cover upper channel C connects It is connected to nozzle.

It is connected through a screw thread between the upper cover and cylinder body.

It is detachably connected between the lower cover and cylinder body by screw.

It is clearance fit between the nozzle and lower cover, and the nozzle is fixed in lower cover by nozzle nut.

It is attached between the wear-resisting seat and lower cover by screw thread.

Between the spool guide sleeve and upper cover chamber be clearance fit, and between the spool guide sleeve and upper cover by Circlip for hole is fixed.

Yx type sealing ring is provided between the spool guide sleeve and spool.

It is all provided between the upper cover and lower cover and cylinder body, between lower cover and nozzle, between the top of spool and upper cover chamber It is equipped with O-ring seal.

Beneficial effect of the invention: in the use of the present invention, threaded connection hole C connects High Pressure Pure Water, threaded connection hole B is connect Abrasive flows (mixing of water+and pellet), threaded connection hole A connects control water, and threaded connection hole D connects pressure sensor；

Original state, threaded connection hole A are connected to high pressure water, into upper cover chamber, act on spool, spool is made to be displaced downwardly to spool It is formed and is sealed with wear-resisting seat, be now in spool closed state, the atmosphere in spool folding process in air cavity is by 26 gas vents Discharge, during this, threaded connection hole C, threaded connection hole B disconnect；

Working condition, threaded connection hole A take back water tank, and threaded connection hole B connects high-pressure abrasive material stream, and abrasive material flows into mixing chamber Afterwards, it acts on spool, makes spool by upward power, spool moves up, and valve core opening size is controlled by adjustment sheet, adjusts when removing When nodal plate, valve core opening is maximum, and adjusting chip size is optional, to meet the requirement of different sizes of experimentation split shed, in spool During moving up, by exhaust gas inlet hole in air cavity, hole of the abrasive flows through wear-resisting seat from spool lower ending opening enters in channel C, Threaded connection hole C connects high pressure water, and hole, channel B through damping block enter in channel C, drives abrasive flows to further speed up, after acceleration Abrasive material flow through injection stream into atmosphere, beat to material surface, form material surface is modified, and the effect of damping block is to make abrasive material The pressure that stream enters mixing chamber is higher than the pressure of High Pressure Pure Water, avoids flowing backwards；

Pressure sensor can the variation of real-time monitoring outlet pressure, while when spray nozzle clogging, the variation of pressure sensor can be instructed Operator takes measures, and avoids mechanical disorder；

After the completion of work, original state is repeated；

It is integrated with fluidic vectoring thrust that accurately controlling for water-bindered pill mixing may be implemented through the invention.
