Embodiment
Automatic drain valve comprises valve body and control mechanism.Described valve body comprises stifled 4, the block water plate 7 of valve seat 1, valve pocket 5, pull bar 6, glue, valve seat 1 is provided with handle card 3, handle card 3 left sides are provided with the screw thread that is screwed on the running water pipe, handle card 3 right sides are provided with the screw thread that is screwed into as valve pocket 5, be provided with the inner nozzle 17 of opening or closing in the valve seat 1 for glue stifled 4,17 sides, inner nozzle are provided with the oblique mouth of a river 16, and tiltedly the mouth of a river 16 1 sides are oblique waterwall 15.Described valve pocket 5 one ends are provided with valve pocket side opening 8, are provided with water outlet 13 below the valve pocket 5, and valve pocket 5 is screwed on the screw thread on handle card 3 right sides of valve seat 1, and the water outlet 13 on the valve pocket 5 is communicated with the oblique mouth of a river 16 on the valve seat 1.The perforation of described inner nozzle 17, oblique waterwall 15 and valve pocket side opening 8 are on same axis, pull bar 6 is installed in the perforation and inner nozzle 17 of valve pocket side opening 8, oblique waterwall 15 successively, tiltedly the perforation of waterwall 15 is identical with the aperture of valve pocket side opening 8, inner nozzle 17 is greater than the perforation and the valve pocket side opening 8 of oblique waterwall 15, block up 4 less than 6 gluings of the pull bar in the valve, glue blocks up 4 inlet channels less than the behaviour area.The inlet channel place is provided with filter screen 2, is provided with guiding groove 14 in the water outlet 13 below the valve pocket 5, and pull bar 6 left end heads are made as taper 18, for reducing the resistance of water.Glue stifled 4 is sleeved on the set groove of pull bar 6 left ends, makes cover more firm in the above, and pull bar 6 the other ends are provided with recessed card 10.Described control mechanism comprises ball float 12, nut 19, ball lever 11 and bar ear 9.Bar ear 9 is for having the Lever type bar ear of bend angle 110 degree, bar ear 9 passes the set recessed card 10 of pull bar 6 one ends, bar ear 9 upper ends are contained in set biside plate 20 tops of valve pocket 6 right-hand members by screw, bar ear 9 can be around screw turns, bar ear 9 lower ends are threaded with ball lever 11, and the nut 19 of solid welding is threaded on ball lever 11 the other ends and the ball float 12.Valve seat 1 is with after valve pocket 5 is connected, the inner chamber of its formation is divided into hyperbaric chamber and underpressure chamber, on the pull bar 6 of underpressure chamber block water plate 7 is housed, prevent that the slit is gone out between bar on the oblique waterwall 15 in hyperbaric chamber and the hole water retaining is in the underpressure chamber, flow out by water outlet 13, guiding groove 14, tiltedly the pull bar perforation is played the glue stifled 4 that makes on the bar and is steadily opened, closes operation on the waterwall 15.
Working principle:
As shown in Figure 4, valve body is close to the water vat upper edge, level is screwed on the intake pipe, when the water vat lack of water, the position of ball float 12 is in the minimum point of valve, ball float 12 produce leverages from gravity by ball lever 11, bar ear 9, the power of closing that the top power that 9 pairs of pull bars of bar ear 6 produce produces glue stifled 4 greater than water pressure in the inlet channel and current; Water station different number of times every day supply water, after stopping, there are not current in the intake pipe, hydraulic pressure, glue stifled 4 is not produced the power of closing, when this moment, ball float 12 descended with the water surface, glue stifled 4 is opened, valve is in the state that backs down pull bar 6 gluings stifled 4, and water just can enter valve body from water supply line, and water is discharged through water outlet 13 and flow in the water vat, ball float 12 floats with the rising of the water surface, outwards spur pull bar 6 by bar ear 9, glue stifled 4 is produced close power, the hydraulic pressure in the intake pipe in addition, current are to the glue stifled 4 common thrusts that produce, final current blocking-up is closed, and stops to supply water.This moment, the water surface was no more than the water vat upper edge, because bar ear 9 bend angle that ball lever is threaded are greater than 90 degree, between 100 degree are spent to 120.When resident family after water intaking is used in the cylinder at every turn, ball float 12 reduces with the water surface again and descends, and ball float 12 makes bar ear 9 back down glue stifled 4 on the pull bar again, make glue stifled 4 leave inner nozzle 17, water can pass through, and ball float rises with the water surface again, the so automatic open and close of drain valve, the work that goes round and begins again.
