Brief description of the drawings
Fig. 1 is the exploded view of the embodiment of the utility model one；
Fig. 2 is the installation diagram of the embodiment of the utility model one.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model.
Referring to Fig. 1 and Fig. 2, this automatic exhaust steam valve, including valve component, valve component is interior to be provided with valve pocket a；On in valve pocket a
Lower floating has buoy 9；The valve element 4 with exhaust passage 4.1 is provided with valve component, the one end of exhaust passage 4.1 connects valve pocket a,
The other end connects air；The pull bar 2 of elastic reset is movably set with valve element 4, pull bar 2 opens and closes exhaust passage 4.1；On buoy 9
Floating effect pull bar 2 closes exhaust passage 4.1, valve pocket a and atmospheric isolation；Buoy 9 declines, and it is logical that the elastic reset of pull bar 2 opens exhaust
Road 4.1, valve pocket a and atmosphere.This structure opens and closes exhaust passage 4.1 by the effect pull bar 2 that fluctuates of buoy 9, with reality
Existing exhaust effect, its is simple and reliable for structure, and service life is grown.
Furtherly, the part of valve element 4 exposes to valve component, and exposed parts are bolted with bonnet 6, valve element 4 and bonnet 6 it
Between be provided with the first sealing ring 5, user can be by rotating the manual opening-closing exhaust passage 4.1 of bonnet 6.
Furtherly, the one end of pull bar 2 is provided with engaging lug 2.1, and pull bar 2 is articulated with valve element 4 by engaging lug 2.1, each other
Between have torsion spring 7, the both ends of torsion spring 7 are respectively acting on pull bar 2 and valve element 4, torsion spring 7 by locating shaft 8 positioning be assemblied in valve element 4
On, the downward elastic reset in the presence of torsion spring 7 of pull bar 2 rotates.During downward elastic reset, exhaust passage 4.1 is opened.
Furtherly, the end set of pull bar 2 has the silicagel pad 3 of cylinder, the sealing closing of the Float upward function silicagel pad 3 of buoy 9
The Single port of exhaust passage 4.1, silicagel pad 3 effectively improve sealing during closing, avoid sluicing and lose heart.
Furtherly, valve pocket a and buoy 9 are set in cylinder respectively, and between having between valve pocket a inwalls and the outer wall of buoy 9
Gap, valve body a match with the structure of buoy 9, and effective control point 9 fluctuates, and make the floating of buoy 9 more smooth, and avoid
Displacement.
Furtherly, the top of buoy 9 is provided with depression 9.1, and when buoy 9 floats, pull bar 2 and valve element 4 are placed in depression 9.1,
Air bleeding valve overall volume reduces.
Furtherly, valve component includes the upper lid 1 and valve body 11 for the assembling that is mutually spirally connected, and is fitted to each other and is assembled to form valve pocket
A, and the second sealing ring 10 is equipped with each other；Valve element 4 exposes to the surface of lid 1, the connecting water pipe of valve body 11.
This air bleeding valve is installed on the peak of system, when gas enter valve pocket a in and be gathered in valve pocket a tops, with gas
Body increases, pressure rise, when gas pressure is more than system pressure, gas can decline the water surface in valve pocket a, buoy 9 with
Water level declines together, and now, the elastic reset of pull bar 2, exhaust passage 4.1 is opened, gas discharge；After gas drains, on water level
Rise, buoy 9 rises therewith, and overcomes elastic force to act on pull bar 2 upwards, closes exhaust passage 4.1.
When producing negative pressure in system, the water surface declines in valve pocket a, and exhaust passage 4.1 is opened, due to now external atmosphere pressure
Power is bigger than system pressure, so air can enter system by exhaust passage 4.1, prevents the harm of negative pressure, such as tightens bonnet 6,
Exhaust passage 4.1 is closed, and air bleeding valve stops exhaust；Under normal circumstances, bonnet 6 is in opening.
Above-mentioned is preferred scheme of the present utility model, and general principle of the present utility model, principal character has been shown and described
And the advantages of the utility model.Those skilled in the art should be recognized that the utility model is not restricted to the described embodiments, on
State and simply illustrate principle of the present utility model described in embodiment and specification, do not departing from the spirit and scope of the utility model
On the premise of the utility model also have various changes and modifications, it is new that these changes and improvements both fall within this claimed practicality
In the range of type.The utility model requires protection scope is defined by appended claims and its equivalent.
