Impurity get rid of mechanism:
Unavoidably containing trace impurity in the water of conveying, with the passing of time must be with the presence of in partial product valve, to large and small steam vent (radial hole) Have undesirable effect, such as, be embedded on sealing surface and cause leakage or blocking small de-air hole, it is therefore desirable to periodically clear up.Cleaning Method is as follows: rotates handwheel 15, makes push rod 16 decline, until big steam vent e is opened, in valve with impurity press water from Big steam vent e sprays;Clean out, anti-phase rotation handwheel 15, push rod 16 must be risen to extreme higher position.Mechanism is also Have following two functions: 1) just in case big steam vent is frozen, can crush by method;2) sometimes need during first water supply to confirm Whether it is filled with water in pipeline, now, first confirms that whether the guide post of lifting cover 7 is in extreme higher position, then fall push rod 6, open big steam vent e, if there being water to discharge, then can confirm that and pipeline has had been filled with water, because air bleeding valve is typically mounted at The peak of pipeline.
The operation principle of the present invention:
In valve anhydrous time (Fig. 1), ball float 3 is positioned at the bottom of ball float cover 4, and lifting cover 7 is in extreme lower position, now taper bolt 5 with The axial taper hole g of lifting cover 7 guide post lower end is to separate.When after first or tubing are overhauled again to piped water supply, In pipeline, substantial amounts of air enters in ball float cover 4 through service valve, water inlet a, inlet opening b, annular chamber H2, exhausting window d, with Quickly discharged by big steam vent e and discharge chamber H3 afterwards.Owing to air bleeding valve is typically mounted at the peak of pipeline, therefore When, after the air emptying in pipeline, water is first filled with pipeline, then enter air bleeding valve by water inlet a;Due to annular air chamber H1 is open downwards, when waterborne be raised to its end opening time, annular air chamber H1 becomes an airtight air chamber, and therefore water will not Enter, so certain thickness annular air layer can be formed with in the whole periphery of air bleeding valve;Enter the water of valve by water inlet Hole b rises in annular chamber H2, simultaneously water by water inlet aperture c enter ball float cover 4 bottom, ball float 3 under buoyancy on Rise, rise together with drive lifting cover 7 after conical bore g is closely sealed at taper bolt 5, until the seal closure of lifting cover 7 lower end and sealing Pad 9 contact, under buoyancy by big steam vent e close, water-tight;Moment before closing, the air in annular chamber H2 is the most Draining, it is allowed to have a small amount of water to discharge from big steam vent e, the water of discharge is by the drain tank h on valve gap 10 lower surface Discharge;Simultaneously under buoyancy, taper bolt 5 and axial taper hole g are tightly pressed together, and are all squeezed by the water in taper hole g Go out, and water-tight, air tight;So far Quick air-discharge terminates (Fig. 2).When Quick air-discharge terminate, water-filling completes, large and small (the least Hole) after vent closure, above ball float 3, remain partial air, this partial air is airtight, has certain pressure, because of This is when normal water supply, and big steam vent e will not open.Along with the change of temperature and pressure in water supply process, in water Air is released, the Spatial Agglomeration above ball float 3, below lifting cover 7, and air pressure constantly raises, water level decreasing in valve, Buoyancy suffered by ball float 3 also decreases, when the weight of ball float 3 exceedes suffered buoyancy with conical bore g upper end area because of inside and outside During upwards thrust sum suffered by pressure reduction, ball float 3 declines, and small de-air hole (warp-wise aperture) f opens, calming the anger above ball float 3 Body is discharged by axial taper hole g and inlet opening c;After body of calming the anger is discharged, in valve, water level raises, and ball float 3 rises, again By little (radial hole) vent closure, such iterative cycles.Air takes a small amount of moisture out of when small de-air hole is discharged unavoidably, as Fruit uses traditional structure, and water will accumulate in little (radial hole) steam vent, blocks causing icing severe cold season Little (radial hole) steam vent.The structure that the present invention uses is as it was previously stated, all can squeeze the moisture accumulated in small de-air hole Go out, thus without occurring because of the fault of frost blocking.
When pipe drainage, producing negative pressure in pipeline, in valve, water level declines rapidly, and ball float 3 falls back to the end of ball float cover 4 Portion, lifting cover 7 falls back to minimum point, and big steam vent e opens, extraneous air by the order contrary with during aerofluxus to pipeline Interior QI invigorating, it is therefore prevented that pipeline damages because producing negative.
As it has been described above, because annular air chamber H1 is airtight, so water will not enter, this is equivalent to air bleeding valve by one The thicker annular air layer of layer is surrounded, and it is elastomer, is again heat insulation layer, therefore can absorb the impact that water produces Ripple, and make air bleeding valve from frost, if used in severe cold area, spacer 6 can use the material that heat transfer coefficient is low.Additionally, from The water that large and small steam vent is discharged can be discharged by some drain tank h;Being retained in the water in axial taper hole g can be by entirely Portion extrudes, and so can prevent large and small steam vent from freezing, it is ensured that air bleeding valve reliably works.The present invention is used in severe cold area, Can Anti-freezing. again can water hammer-resistant;If used in torrid areas, merely to water hammer-resistant, then the most slightly modified just Row.
