Description
Technical field
The utility model is related to a kind of air bleeding valve more particularly to a kind of impact-resistant air bleeding valves.
Background technology
Air bleeding valve is the important device in water delivery pipeline system, is typically mounted on the eminence of water delivery pipeline system or holds one's breath
Place.
The effect of air bleeding valve is:When occurring bulk gas in pipeline, air bleeding valve can work as pipe with the air in discharge line
When generating a small amount of gas in road, a small amount of gas that air bleeding valve can in time in discharge line ensures defeated to reduce water delivery vapour lock
Water stablizes and pipeline safety;When occurring negative pressure in pipeline, air bleeding valve can quickly suck gas, prevent pipeline from being inhaled flat or close
Situations such as envelope is destroyed.
The structure type of existing air bleeding valve is more, and it is entitled " a kind of air bleeding valve " that such as application No. is " 201610299783.7 "
Patent of invention, application No. is " 201620773702.8 " entitled " a kind of air inlet and exhaust valves with micro-exhaust valve " etc., but its
Basic principle is roughly the same.By taking the patent of invention of entitled " a kind of air bleeding valve " application No. is " 201610299783.7 " as an example,
The basic functional principle of air bleeding valve is:(1) when generating bulk gas in pipeline, sealing valve plate and floating ball are all protected under Gravitative Loads
Extreme lower position is held, bulk gas is discharged rapidly by the larger gap between sealing valve plate and valve body exhaust outlet;(2) bulk gas
After discharge, the water in pipeline starts to enter from valve inleting water mouth, and floating ball is begun to ramp up under buoyancy, pushes sealing valve first
The exhaust guide pipe at plate center, closes micro exhaust passage, because exhaust guide pipe is fixedly connected with sealing valve plate, seals
Valve plate is also synchronized and is pushed;(3) floating ball, which pushes, rises until the exhaust outlet of sealing valve plate and valve body is in sealing contact, and valve body is interior to be formed
Confined space keeps under air pressure collective effect of the sealing valve plate in floating ball buoyancy and confined space stablizing, also be formed in pipeline
Voltage stabilizing flow;(4) when there is a small amount of gas evolution, a small amount of gas enters the confined space of valve body, water level decreasing in valve body, floating ball
Decline therewith, the micro exhaust passage being vented on guide pipe is opened, these a small amount of gases are discharged, and it is extensive that water level in rear valve body is discharged
Multiple, floating ball, which rises, again closes micro exhaust passage;(5) when occurring negative pressure in pipeline, water level declines rapidly in valve body, close
Valve plate and floating ball are sealed because air pressure and Gravitative Loads are opened rapidly, ambient atmos quickly enter pipeline.In above-mentioned principle (2) and (3)
Larger gap is sealed when floating ball pushes and seals the sequencing of micro exhaust passage because the structure of different air bleeding valves will produce not
Together, but in principle it is the same that (4), which put all air bleeding valves,.
In actual use, existing air bleeding valve still has some problems according to above-mentioned operation principle, for above-mentioned principle
(2) and for (3), floating ball because hydraulic pressure in pipeline can rapid increase, floating ball buoyancy F at this timeIt is floating> floating ball gravity GBall+ sealing valve
Plate gravity GPlate+ exhaust guide pipe gravity GPipe, floating ball, sealing valve plate and be vented the entirety of guide pipe can be in the trend that centainly accelerates to
Upper movement, therefore sealing valve plate speed can also become larger, in sealing valve plate and exhaust outlet moment in sealing contact, according to punching
Formula F t=mv is measured, sealing valve plate can not only will produce one by the very big reaction force of exhaust ports, this reaction force
Fixed noise, and be easy to cause sealing valve plate generate deformation, while this reaction force can also pass to exhaust guide pipe and
Floating ball because floating ball sheet as thin-wall construction and exhaust guide pipe cross-sectional area it is smaller, the reaction force meeting passed over
It is applied topically to floating ball surface, floating ball is caused to deform upon, according further to the interaction of power, sealing valve plate also can be to exhaust outlet
The sealing ring etc. at place causes to impact, and sealing ring is caused to be easily damaged, so the presence of this impact force, zero more to air bleeding valve
Part is all affected, and is particularly easy to cause damage of components, causes air bleeding valve ineffective.
In addition, for above-mentioned principle (4), when forming confined space in valve body, gas in confined space can be because
Hydraulic pressure effect compression certain volume, forms high pressure gas, at this time floating ball buoyancy FIt is floatingThe relative pressure F of+compressed gasGas=floating ball weight
Power GBall+ sealing valve plate gravity GPlate+ exhaust guide pipe gravity GPipe+ exhaust outlet support force fExhaust outlet, the wherein relative pressure of compressed gas
FGasIt is compressed gas to the pressure of sealing valve plate with ambient atmosphere to the pressure difference of sealing valve plate, floating ball, sealing valve plate and exhaust
Guide pipe keeps stablizing under the balance of above-mentioned active force, and according to F=PS it is found that sealing valve plate area is bigger, air pressure at this time carries
The support force of confession is bigger, this is also that existing sealing valve plate surface area designs all larger reason, and existing sealing valve plate is usually all set
It is calculated as a pot shape, increases the design of surface area but also sealing valve plate intensity itself is weaker, the sealing valve plate seals in front
The impact force being subject to when contact is also easier to make sealing valve plate itself be deformed.After a small amount of gas enters valve body, water level omits
Micro- decline, floating ball buoyancy FIt is floatingReduce, but because the pressure that compressed gas provides be enough to support sealing valve plate and exhaust guide pipe and
Floating ball buoyancy F at this timeIt is floating> floating ball gravity GBall, floating ball is without departing from exhaust guide pipe, as follow-up more a small amount of gases enter
Valve body, water level decreasing incrementally increase, as floating ball buoyancy FIt is floating=floating ball gravity GBallWhen, between floating ball and the lower port of exhaust guide pipe
Because external and internal pressure difference is still not easily disconnected from, water level still constantly declines during the entrance of a small amount of gas at this time, until floating ball
Buoyancy FIt is floatingLess than floating ball gravity GBallAnd GBallEffect can overcome exhaust guide pipe lower end external and internal pressure difference and floating ball buoyancy FIt is floatingWhen, floating ball
It can be just detached from exhaust guide pipe, micro exhaust passage can just be opened;Because compression gas atmosphere is obviously big in valve body confined space
In external atmosphere pressure, gas can drastically be discharged, and because when micro exhaust passage is opened, in original confined space gas-storing capacity compared with
Greatly, can be accelerated to float under buoyancy again by rapid water-filling, floating ball in valve body, final impact again is in the lower end of exhaust guide pipe
On mouth, the floating ball and exhaust that are generated after this frequently micro exhaust are oriented to the impact between infratubal port, also become floating ball rapid wear
Bad key factor.
The reason of above problem occurs be mainly:(1) all it is to contact firmly between floating ball and sealing valve plate, although some are vented
Valve increases rubber sleeve in the lower end of exhaust guide pipe, is used as buffering while improving sealing effect, but rubber sleeve is in frequency
It is numerous impacted in the case of also easily damage, problem does not solve fundamentally;(2) existing air bleeding valve micro exhaust passage is opened
It opens, overcomes buoyancy and exhaust to be oriented to infratubal port inside and outside differential pressure to realize, too by floating ball its own gravity after water level decreasing merely
Be easy to cause that gas-storing capacity in confined space is excessive so that every time after micro exhaust floating ball to be vented the impact of guide pipe compared with
Greatly.

Water level no longer changes in valve body 1, and voltage stabilizing flow is formed in pipeline;(4) when there is a small amount of gas evolution, described in a small amount of gas entrance
Inside valve body 1, water level is begun to decline in the valve body 1, the buoyancy F of the hollow floating body 2It is floatingIt is gradually reduced, as buoyancy FIt is floating=bullet
Spring force FSpring+ floating ball gravity GBallWhen, because of internal and external pressure difference, the hollow floating body 2 does not take off the lower port in micro- row channel 32 yet
From the exhaust guide pipe 31, then after having a small amount of gas to enter, water level slightly declines again in the valve body 1, at this time FIt is floating< FSpring+
GBall, the spring force that spring 35 is floated in the resistance is easy to overcome internal and external pressure difference, pushes the hollow floating body 2 to be detached from the exhaust and lead
To pipe 31, micro- row channel 32 is opened, realizes micro exhaust;From above-mentioned principle, those skilled in the art are very easy to find,
The present embodiment makes the hollow floating body 2 be detached from the exhaust guide pipe 31 to realize that the active force of micro exhaust not only only has the sky
The gravity of flighty and impatient body 2 further includes the spring force that spring 35 is floated in the resistance, when micro- row channel 32 is opened, in confined space
Gas-storing capacity be it is very small, so the present embodiment compared with prior art for, when opening micro- row channel 32, because of institute
The gas-storing capacity stated in valve body 1 is considerably less, and the micro exhaust process of the present embodiment can be very short, and the hollow floating body 2 will not decline too
Big distance, the water level in the valve body 1 restores just more gentle for compared with prior art, in addition the hollow floating body 2 floating
The cushioning effect that spring 35 can be floated by the resistance again in the process, between the hollow floating body 2 and micro- row's sealing shroud 34
Impact is apparent to be eliminated;(5) when occurring negative pressure in pipeline, water level declines rapidly in the valve body 1, the sealing valve plate 3 and institute
Hollow floating body 2 is stated because air pressure and Gravitative Loads are opened rapidly, ambient atmos quickly enter pipeline.
In conclusion sealing valve plate 3 described in the present embodiment, when in sealing contact with the exhaust outlet 11, spring is floated in the resistance
35 can reduce the impact between parts to the buoyancy of the hollow floating body 2 into row buffering;A small amount of gas is not in the valve body 1
When disconnected aggregation, spring 35 is floated in the resistance so that the hollow floating body 2 is taken off as early as possible with the gravity collective effect of the hollow floating body 2
Micro- row channel 32 is opened from the exhaust guide pipe 31, because gas-storing capacity is smaller, when micro exhaust is described hollow floating
Body 2, which rises, to be accelerated to be not obvious, while the cushioning effect of spring 35 is floated plus resistance, the hollow floating body after frequent micro exhaust
Impact between 2 and the exhaust guide pipe 32 between the hollow floating body 2 described in other words and micro- row's sealing shroud 34 obviously disappears
It removes, significantly improves the service life of parts.The present embodiment is solved with better simply structure and is generally faced in the prior art
