In Chinese patent [CN202252273U], a kind of diversion type floater type air exhausting valve is disclosed, comprise the valve body that valve body I and valve body II link together and be placed in the float in valve body, the top of valve body I is provided with exhaust port, the bottom of valve body II is provided with inlet hole, the bottom of the valve body I of inlet hole and floater component is provided with air guide mechanism, on this air guide mechanism, be evenly equipped with several gas ports, this patent can effectively be avoided large entraining air stream directly to blow causing float to takeoff suddenly and the phenomenon of closure tip exhaust port occurs, has improved the reliability of air inlet and exhaust valve.
But, the internal capacity of the float in the air inlet and exhaust valve that above-mentioned model utility is described is fixed, and can the volume of the weight of float itself and float inner chamber be to affect float change with the liquid level in outlet valve the key factor moving normally, fast and effectively, when in pipeline, liquid changes, (medium of pipeline transport changes, density changes thereupon), need to change float, make the buoyancy of float in this liquid be enough to allow fast float move in outlet valve, thereby carry out exhaust or inflation.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and a kind of vent valve float is provided, and technical problem to be solved in the utility model is that how to realize float volume adjustable, to improve the versatility of float.
The purpose of this utility model can realize by following technical proposal: a kind of vent valve float, it is characterized in that, described float comprises a body, described body has a downward opening main float chamber, described float also comprises that one is plugged in described main float chamber and by the airtight sealing seat of main float chamber, thereby between described sealing seat and body, is provided with a connection part that can regulate relative position between sealing seat and body to change described main float chamber volume.
Working principle of the present utility model is: the buoyancy of the float of equal in quality and volume in the liquid of different medium is different, the difference of the liquid medium in conveyance conduit, the float that need to match, the sensitivity of guarantee float in outlet valve and reliability etc., vent valve float described herein, by connection part, regulate the relative position between body and sealing seat, thereby it is adjustable to realize main float chamber volume, to adapt to the outlet valve in the conveyance conduit of liquid mediums; This programme does not change the weight of float itself, and convenient while regulating the position between body and sealing seat, it is more accurate to regulate.
In above-mentioned vent valve float, described connection part comprises the outside thread that is opened on described sealing seat outer wall and is opened in the internal thread on described main float chamber inwall, and described internal thread coordinates with described outside thread.Between sealing seat and body, be threaded connection, rotary seal seat can regulate the relative position between sealing seat and body, thereby regulates the volume of main float chamber.
In above-mentioned vent valve float, as another kind of technological scheme, described connection part comprises the stuffing box gland being arranged on main float chamber inwall, described sealing seat and described stuffing box gland drive fit.Sealing seat can slide along the inwall of main float chamber, both drive fits, and sealing effect is also better.
In above-mentioned vent valve float, in described sealing seat, there is an opening up auxiliary float chamber, described auxiliary float chamber communicates with described main float chamber, and described auxiliary float is indoor is provided with some stiffening ribs.The weight of whole float can be reduced in auxiliary float chamber, increases the volume of float seal cavity, and stiffening rib can strengthen the intensity of sealing seat, improves the sealing reliability between sealing seat and body.
In above-mentioned vent valve float, the lower end of described sealing seat has one and controls end.Control end and be convenient to rotation or pushing sealing seat, thereby regulate the relative position between sealing seat and body.
In above-mentioned vent valve float, the upper end of described body is provided with a valve rod.When float cuts out outlet valve, valve rod inserts in the valve opening of outlet valve and valve opening is blocked.
Compared with prior art, the utlity model has following advantage:
1, vent valve float described herein, regulates the relative position between body and sealing seat by connection part, thereby it is adjustable to realize main float chamber volume, to adapt to the outlet valve in the conveyance conduit of liquid mediums.
2, this programme does not change the weight of float itself, and convenient while regulating the position between body and sealing seat, it is more accurate to regulate.
