Description
Technical field
The utility model belongs to the processing technique field of the rotary valve of oxygenerator, specifically, is on a kind of oxygenerator
Movable valve plug fine grinding device.
Background technology
In the market, the nitrogen oxygen separating method for oxygenerator mainly have electromagnetism seperating vale, solenoid-driven it is pneumatic
Valve, ceramic core rotating separation valve etc.；Although electromagnetism seperating vale and electromagnetic drive pneumatic operated valve materials are easy, exist cost compared with
The shortcomings of high, driving air pressure is larger and needs extra drive.Ceramic core rotating separation valve largely solves electricity
The shortcoming of Magneto separate valve and electromagnetic drive pneumatic operated valve, but because its movable valve plug and fixed valve plug are ceramics, both rub at circulation rotating
Wipe, use for a long time can produce violent sound；Further, since the coefficient of friction of ceramics is big, contact of the movable valve plug with fixed valve plug
If rough between face can cause severe friction, so as to cause the generation for killing phenomenon, the service life of product is influenceed.Therefore,
Chinese patent CN 205578787U disclose a kind of nitrogen oxygen circulation valve, and the rotary valve includes a movable valve plug, such as Fig. 1 and Fig. 2 institutes
Show, the cross section of the movable valve plug 1 is T-shaped, it is necessary to which fixed valve plug is fixedly mounted on valve body during installation, then by movable valve plug 1
It is installed in rotation on fixed valve plug.Therefore, it is high to the flatness requirement of fixed valve plug and movable valve plug 1.If the bottom of movable valve plug
Face out-of-flatness, when coordinating with ceramic fixed valve plug, easily occurs gas leakage, causes the oxygen concentration of rotary valve inadequate, so that two molecular sieves
It is uneven that tank cuts gas, influences oxygen effect processed.
Existing movable valve plug bottom surface polishing process mainly has two kinds, and one kind is hard grind method, and another is manual grinding method.Firmly
Mill method is is mounted directly movable valve plug in the bottom of motor, or sets between motor and movable valve plug spring, the bottom surface of movable valve plug
Down, during polishing, the bottom surface of movable valve plug is placed on sand paper, starts motor polishing.The dynamic valve obtained in this way
Core, after tested, qualification rate are very low, and the flatness of movable valve plug bottom surface is nearly all unqualified.Manual grinding method, i.e., hand-held dynamic valve
Core, and the bottom surface of movable valve plug is placed directly within manual grinding on sand paper, the active force being pressed in due to human hand on movable valve plug is uneven,
It is easily caused the bottom surface polishing out-of-flatness of movable valve plug.
In addition, the flatness of existing movable valve plug bottom surface is all observed by the naked eye, after determining that movable valve plug bottom surface is smooth,
Whole rotary valve is assembled again, finally debugged, to detect the qualification rate of rotary valve.If detecting that the bottom surface of movable valve plug is uneven
It is whole, then movable valve plug is disassembled into continuation polishing, the flatness of movable valve plug bottom surface is then observed by the naked eye again.Because naked eyes are seen
Examine application condition greatly, on the one hand influence the qualification rate of movable valve plug, on the other hand, influence the manufacturing time of movable valve plug and be manufactured into
This.

During movable valve plug, in the through hole of the cylinder insertion beam above movable valve plug, for keeping balancing damping.
Further, the beam is rubber sleeve and silica gel sheath etc..
According to the utility model, the bottom of the sleeve offers transom, the shape for radiating, observing motor shaft rotation
Condition and remove chalk dust removing etc..
According to the utility model, the length of sleeve is stretched out for 1cm-1.5cm in the bottom of the movable valve plug.
According to the utility model, the rotary speed of the motor is 1400r/min.
Movable valve plug fine grinding device of the present utility model, its advantage is：
The 1st, sleeve is set outside motor shaft, in use, the bottom of sleeve is used for fixing sand paper, so that movable valve plug can be maintained at
It is in rotary moving within the scope of one；
The 2nd, limited block is set outside motor casing, and limited block is passed to the bar hole of sleeve so that motor shaft is only in axial direction
Upper rotary motion, it is ensured that the gravity of motor directly bears against the center of movable valve plug, so that it is guaranteed that grinding homogeneity；
3rd, under nature, sleeve is stretched out in the bottom of movable valve plug, during polishing, because bottom and the sand paper plane of sleeve are in
Impaction state, movable valve plug realizes polishing, its grinding homogeneity under the axial rotation effect of the gravity and motor shaft of motor itself；
4th, movable valve plug can produce dust in bruting process, and motor shaft can produce substantial amounts of thermal current in polishing,
The setting of transom, not only can constantly observe the rotary state of motor shaft, can also radiate and remove chalk dust removing.
