Description
Technical field
This utility model relates to heating, the air bleeding valve of heat supply process, particularly relates to a kind of Novel vent valve.
Background technology
Air bleeding valve is applied to the pipeline air exhaust waters such as independent heating system, central heating system, heating boiler, central air-conditioning, floor heating and solar heating system.Because generally all dissolved with certain air in water, and the dissolubility of air reduces along with the rising of temperature, such water gas during circulation gradually is separated from the water out, and the bubble even gas column that formation of gradually getting together is big, because there being supplementing, so often there being gas to produce of water.
When system has gas overflowing, gas can be climb along pipeline, it is eventually collected in the peak of system, and air bleeding valve is the most all arranged on system peak, be gathered in the top of air bleeding valve when gas enters air bleeding valve valve pocket, along with the increasing of gas in valve, pressure rises, and when gas pressure is more than system pressure, gas can make the intracavity water surface decline, floating drum declines with water level, opens air vent；After gas drains, water level rises, and floating drum rises the most therewith, closes air vent.Same reason, when producing negative pressure in system, in valve pocket, the water surface declines, Exhaust Open, owing to now external atmosphere pressure force rate system pressure is big, so air can enter system by air vent, prevents the harm of negative pressure.As tightened the bonnet on exhaust valve, air bleeding valve stops aerofluxus, it is generally the case that bonnet should be in opening.Air bleeding valve can also support the use with isolating valve, it is simple to the maintenance of air bleeding valve.Floor heating (underground heat) is set of system, and fixed installation and the connection of automatic exhaust valve pipe fitting from grounding heat coil tube to water knockout drum have strict technological requirement, when heating in the winter time, opens floor heating user firstly the need of aerofluxus, then aerofluxus is accomplished by using air bleeding valve.Heating air vent valve one is installed on system peak, is used for discharging the valve of the air pocket produced in heating system and water supply line.In the ordinary course of things, dissolved air containing about 2VOL% in water, during water delivery, these air are constantly discharged by water, being gathered at the high point of pipeline, form air bag (AIRPOCKET) and make water delivery become difficulty, therefore the conveyance power of water of system can decline about 5-15%.This micro-exhaust valve major function is exactly to get rid of the dissolved air of this 2VOL%, and appropriate means in skyscraper, on-site pipe arrangement, small pumping station in order to protect or improve system emptying effectiveness and save the energy.
Air bleeding valve is applied to the pipeline air exhaust waters such as independent heating system, central heating system, heating boiler, central air-conditioning, floor heating and solar heating system.Because generally all dissolved with certain air in water, and the dissolubility of air reduces along with the rising of temperature, such water gas during circulation gradually is separated from the water out, and the bubble even gas column that formation of gradually getting together is big, because there being supplementing, so often there being gas to produce of water.Just prolong for this and bear this noun of air bleeding valve, also solve many problems at daily life.When starting water filling in pipe, chock plug rests on open position, carries out a large amount of aerofluxus, when air is drained, valve internal water accumulation, ball float is floated, transmission chock plug, to closed position, stops a large amount of aerofluxus, when in pipe, water normally carries, arriving certain degree, water level decreasing in valve in being gathered in valve if any small air, ball float declines therewith, now air is discharged by aperture, when water pumper stops, during in-pipe flow sky or when meeting pipe interior generation negative pressure, now chock plug is opened rapidly, sucks air, it is ensured that pipeline is complete.Valve is installed at pump water outlet or in delivery water pipeline; in order to the air of assembly in a large amount of drains; or be emitted in air in the micro-air of pipeline higher position assembly; to improve pipeline and water pumper service efficiency; and once there be negative pressure to produce in pipe; this valve immediately wicks into outside air, with the damage protecting pipeline to be produced because of negative pressure.Air bleeding valve for DN >=100 uses Split type structure, is made up of a large amount of air bleeding valves and automatic exhaust steam valve, to adapt to the use requirement of pipeline pressure.Automatic exhaust steam valve should use multiple leverage, makes ball float buoyancy significantly be amplified, and closedown water level is low, and impurities in water is difficult to contact sealing surface, and air vent is not plugged up, and its performance of anti-blockage is greatly improved.Simultaneously under high-pressure situations, due to the afterburning effect of multiple lever, making ball float can synchronize to decline with water level, opening and closing element will not be held by high pressure as conventional valves, thus normal exhaust.
Current existing air bleeding valve can cause liquid to leak in use, installs inconvenience simultaneously, and air-tightness effect is bad.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in construction, and air-tightness is good, is suitable for the aerofluxus of heating equipment, does not results in the air bleeding valve of liquid leakage.
