Description
Technical field
This utility model relates to a kind of air bleeding valve for fire protection sector, uses ball float, hinge rotary seal knot
Structure, profile is cylindrical；Air and real-time eliminating in water when air bleeding valve can get rid of pipe network initial water-filling dissolve
Air, when water level rises close seal, belong to fire water-supply field.
Background technology
Current air bleeding valve, ball float blows lower Yi Shangyi at high velocity air, closes by mistake, it is impossible to get rid of completely
Air in pipe network；Sealing gasket often separates with hinge, disengages and seal failure；Capacity is little；Such row
Air valve can not meet the application requirement of boats and ships, skyscraper, large-scale logistic storage etc..
Summary of the invention
Lower closedown by mistake is blown at high velocity air, it is impossible to get rid of the sky in pipe network completely in order to solve conventional exhaust valve
Gas, sealing gasket and hinge often disengage and lost efficacy, problem that capacity is little；This utility model provides a kind of aerofluxus
Valve, uses ball float, hinge rotational sealing structure, and profile is cylindrical；Sealing gasket hot glue is embedding to be noted in hinge,
Sealing gasket is provided with multiple hot glue embedding note point at center and periphery, enhances both bonding fastnesses and uses the longevity
Life；Valve body upper end is provided with shirt rim, circle-shaped on shirt rim is evenly equipped with 6 screws；Bottom is provided with wire connection in air inlet
Head, has drilled 45 ° of oblique air inlets on the upside of internal thread nipple orifice, prevent high velocity air from blowing floating the impact of ball float
Effect, it is to avoid it closes before coming on water level by mistake, it is ensured that get rid of the air in pipe network completely；Air outlet adapter
Latus rectum reaches Φ 8mm.This utility model in hotel, market, station, boats and ships, skyscraper, large-scale logistics
Storage etc. is with a wide range of applications.
This utility model is achieved through the following technical solutions:
Air bleeding valve by sealing gasket (1), hinge (2), round pin (3), air outlet adapter (4), base plate (5),
Screw (6), valve gap (7), plug screw (8), O RunddichtringO (9), bolt (10), ball float (11), valve
Body (12) forms.Using ball float, hinge rotational sealing structure, profile is cylindrical；Valve gap leads to valve body
Crossing bolt fastening, O RunddichtringO seal, ball float welds with hinge, and hinge is fixed by round pin with base plate,
Base plate is fixed on the downside of valve gap by air outlet adapter, screw, and sealing gasket hot glue is embedding to be noted in hinge；Ball float at ordinary times
Aerofluxus is opened wide by gravity sag, air outlet adapter with hinge；During air bleeding valve water inlet, water level is gradually increasing and makes ball float
Upper shifting, drives the sealing gasket on hinge to contact with air outlet adapter lower plane, realizes sealing.
The beneficial effects of the utility model are: ball float not will be shifted up under high velocity air blows impact, closes by mistake,
Can all get rid of the air in pipe network；Sealing gasket bonds fastness with hinge, and service life is long；Capacity is big,
Reach 160L/min, decrease raw material and expend.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is section of structure of the present utility model.
Fig. 2 is outline drawing of the present utility model.
Fig. 3 is air outlet adapter profile of the present utility model.
Fig. 4 is valve body profile of the present utility model.
Detailed description of the invention
Air bleeding valve by sealing gasket (1), hinge (2), round pin (3), air outlet adapter (4), base plate (5),
Screw (6), valve gap (7), plug screw (8), O RunddichtringO (9), bolt (10), ball float (11), valve
Body (12) forms.Using ball float, hinge rotational sealing structure, profile is cylindrical；Valve gap (7) and valve
Body (12) is fastened by bolt (10), O RunddichtringO (9) seal, ball float (11) and hinge (2)
Welding, hinge (2) and base plate (5) fixed by round pin (3), base plate (5) by air outlet adapter (4),
Screw (6) is fixed on valve gap (7) downside, and sealing gasket (1) hot glue is embedding to be noted in hinge (2)；At ordinary times
Ball float and hinge are by gravity sag, and hinge rotates and relates to without card flexibly, and ball float does not touches with valve interior wall, gives vent to anger
Joint opens wide aerofluxus；During air bleeding valve water inlet, water level is gradually increasing and makes to move on ball float, drives the sealing on hinge
Pad contacts with air outlet adapter lower plane, realizes sealing；Sealing gasket hot glue is embedding to be noted in hinge, sealing gasket in
The heart and periphery are provided with multiple hot glue embedding note point, enhance both bonding fastness and service life；Ball float
Wall thickness, volume, weight press the mechanics design that ball float can float during submergence half in water.This utility model solution
