3rd pressing plate 39.The valve rod 37 seals the 3rd pressing plate 39 of insertion and supporting plate 18 successively.And the valve rod 37 is arranged on positioning
Above post.The valve shaft 20 of the action bars 7 can be pressed on valve rod 37 through ball float 12.
The operation principle of direct-burried air bleeding valve of the present utility model is as follows：
1）During water flowing at initial stage, largely it is vented in valve body 2, now big valve flap 13 is opening；When large quantity of air is drained, water
Into valve body 2, under the buoyancy of water, ball float 12 rises, and big valve flap 13 is withstood on the valve port of the first valve seat 10, macropore row
Air valve is closed；When conduit running, the air of precipitation enters valve body 2, and ball float 12 is because no buoyancy is just begun to decline, and then band
Movable sealing sleeve 24 rolls, and starts to be gradually opened steam vent 23, valve body 2 discharges micro-air.
2）If there is the remaining water of the ejection after exhaust in pillar 1, it can be discharged by non-return valve 6, infiltration ground end, and ground end
Water will not be redirected back into pillar 1；When checking the operation of direct-burried air bleeding valve whether normal exhaust, open direct-burried box 3 on ground
Lid, open detection ball valve 5, check whether gas collection can judge in valve body 2；When needing maintenance, direct-burried box is opened
3, rotation process bar 7, drive rod 19 drives valve shaft 20 to rise, and now valve rod 37 loses the pressure of valve shaft 20, and piston ring 34 is multiple
The position effect of spring 36 is lower to be risen simultaneously, when rising to the back side of supporting plate 18, is closed with the sealing cooperation of the 4th sealing ring 37 self-closing
Valve, now disconnected in valve body 2 with pipeline；Continue the fragment position of rotation process bar 7 one, now between the sealing ring 31 of valve shaft 20 and the 3rd
Sealing be destroyed, press water in valve body 2 release pressure, be changed into without pressure water；Continue rotation process bar 7, the screw thread of action bars 7 arrives
Bottom, revolving force are acted on gland 9, and gland 9 transmits rotating force to bonnet 8 and valve body 2, and projection 14 and the valve body 2 of bonnet 8 lack
Mouth 15 is corresponding i.e. separable, now action bars 7 can be pulled out into ground, then action bars 7, bonnet 8, ball float 12, valve shaft 20 etc.
Ground is all drawn out in the part that action bars 7 connects together, it is possible to achieve maintenance.After having overhauled, same mode is these
Part is put into valve body, i.e. the projection 14 of bonnet 8 is housed in accepting groove 16 from the breach 15 of valve body 2 into valve body 2, then reversely rotation
Turn, projection 14 misplaces with breach 15, you can to complete to install.
In summary, preferred embodiment of the present utility model is these are only, should not be limited with this of the present utility model
Scope.I.e. every simple equivalent changes and modifications made according to the utility model claims book and description, all should
Still belong in the range of the utility model patent covers.
