Description
Technical field
The utility model is related to field of fluid control, and in particular to a kind of air bleeding valve.
Background technology
Micro-exhaust valve is mainly used in various water supply and drainage systems, for having pressure air in continuous discharge line.
The main performance of micro-exhaust valve is embodied on exhaust capacity, i.e., exhaust with pressure when capacity, restriction have pressure tolerance most
Big factor, one is as micro-exhaust valve, valve volume cannot be excessive；Second, floating ball weight cannot be overweight.
Invention content
The purpose of this utility model is to provide that a kind of capacity is big, reliability is high, the air bleeding valve of good airproof performance.
To achieve the goals above, the technical solution adopted in the utility model is：
A kind of air bleeding valve, including valve body and valve deck, valve deck are set to valve body upper end, and valve deck is equipped with gas outlet, valve body lower end
Equipped with inlet, the conical valve seat stretched into valve body is connected on the gas outlet, conical valve seat is equipped with and is connected to gas outlet
Venthole, a floating body is set below conical valve seat, and floating body upper side setting one stretches into groove therein for conical valve seat, recessed
Setting one is corresponding with conical valve seat between slot and conical valve seat and seals the flexible conical seal cap of cooperation, flexible conical seal cap
Lower end be fixedly connected with the lower end of conical valve seat, the upper end of flexible conical seal cap is fixedly connected with floating body, and floating body is equipped with
The inlet opening being connected to groove.
The utility model is further arranged to, and the conical valve seat is small top and big bottom taper, conical valve seat spiral shell
Line is connected on gas outlet.
The utility model is further arranged to, and the conical valve seat lower end extends downwardly a guide rod being vertically arranged,
The pilot hole of one perforation floating body of setting, guide rod and pilot hole clearance fit on corresponding floating body.
The beneficial effects of the utility model：
Air bleeding valve provided by the utility model uses the flexible sealing structure of roller shutter type, can avoid pressure medium
It, the problem of exhaust port area to break through micro-exhaust valve is limited by buoyancy, gravity, will be micro- to the active force of valve opening and closing element
The exhaust capacity for measuring air bleeding valve is promoted, and the sealed rolling mechanism of taper, the characteristics of even more having fully demonstrated this structure, row
Gas area greatly improves, and reliability, leakproofness also increase substantially.
When generating air in pipeline, and entering valve, water level decreasing in valve, floating body declines, and floating body drives cone flexible
Shape seal cap pulls down（Similar to de- socks）, at this time the pressure medium in action flexible seal cap can only positive acting in sealing
Cap, and the lower pulling force of seal cap is slanting, in addition the flexibility of seal cap, pressure medium can not baffle seal cap drop-down；
Therefore pressure medium is to the no any influence of the keying of valve.
In addition, the valve mechanism is simple and reliable, sealing leak source is few, sealed reliable, because sealing area is not by pressure medium
It influences, therefore can accomplish the volume of very little and prodigious exhaust outlet.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the attachment structure schematic diagram of the utility model flexible conical seal cap and conical valve seat.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
The utility model is illustrated below with reference to Fig. 1 to Fig. 2.
A kind of air bleeding valve, including valve body 1 and valve deck 2, valve deck 2 are set to 1 upper end of valve body, and valve deck 2 is equipped with gas outlet 3, valve
1 lower end of body is equipped with inlet 4, is connected with the conical valve seat 5 stretched into valve body 1 on the gas outlet 3, conical valve seat 5 is equipped with
A floating body 7 is arranged in the venthole 6 being connected to gas outlet 3,5 lower section of conical valve seat, and the setting one of 7 upper side of floating body is for conical valve seat
5 stretch into groove 8 therein, and corresponding with conical valve seat 5 and sealing cooperation a flexibility is arranged between groove 8 and conical valve seat 5 and bores
The lower end of shape seal cap 9, flexible conical seal cap 9 is fixedly connected with the lower end of conical valve seat 5, flexible conical seal cap 9 it is upper
End is fixedly connected with floating body 7, and moving up and down for floating body 7 can drive flexible conical seal cap 9 to move, to open and close venthole 6, floating body
7 are equipped with the inlet opening 12 being connected to groove 8, and liquid medium is entered by inlet opening 12 in groove 8.
Conical valve seat 5 is small top and big bottom taper, and conical valve seat 5 is threaded on gas outlet 3.Conical valve seat 5
It is made of pedestal part 51 and conical section 52, pedestal part 51 is threadedly coupled with gas outlet 3, conical section 52 and flexible conical
The sealing cooperation of seal cap 9.
5 lower end of conical valve seat extends downwardly a guide rod 10 being vertically arranged, and a perforation floating body is arranged on corresponding floating body 7
7 pilot hole 11, guide rod 10 and 11 clearance fit of pilot hole, the gap enter convenient for liquid in groove 8, and guide rod 10 plays
Guiding role.
Air bleeding valve provided by the utility model uses the flexible sealing structure of roller shutter type, can avoid pressure medium
It, the problem of exhaust port area to break through micro-exhaust valve is limited by buoyancy, gravity, will be micro- to the active force of valve opening and closing element
