Description
Technical field
The utility model is related to a kind of air bleeding valve, more particularly to a kind of suitable for tilted tube, multifunctional composite height
Speed row
Gas intake valve.
Background technology
In order to improve transfer efficiency and prevent aqueduct to be damaged because of negative pressure, combined high-speed exhaust intake valve
（Hereinafter referred to as air bleeding valve）It is widely used on aqueduct.Its major function is carried out soon by big steam vent during first water supply
Fast a large amount of exhausts, Quick air-discharge is closed after terminating；During normal water supply, the air contained in water gathers at the top of air bleeding valve, with
Being raised and lowered for air pressure, exhaust is repeated by small de-air hole：When occurring negative pressure in aqueduct, for example, have a power failure or overhaul and stop
During water, big steam vent is opened rapidly, and outside air enters pipeline through air bleeding valve, eliminates the negative pressure in pipeline.
The structural shape of air bleeding valve is more, the Integral exhaustion type valve disclosed in wherein CN2758563（Hereinafter referred to as the former）
With the split type air bleeding valve disclosed in CN 103470836（Hereinafter referred to as the latter）Typical construction is classified as by national standard.But this kind of valve
There is problems with use in door： 1）It can not be used on the larger pipeline of gradient, reason is as follows：The former is to make lifting
Cover 7 reliably closes big steam vent 17, and its motion is oriented to by guide rod 16, and guide rod 16 is dynamic to fit over the central axle sleeve of hood 11
In through hole, in addition, to make floating body 5 reliably close small de-air hole 10, it moves and fitted in floating-body cover 3；The latter is to make ball float 602 can
Big steam vent is closed by ground, its motion is oriented to by guide rod 605, in the dynamic guide groove 606 for fitting over valve body lower portion of guide rod 605.When it
When being arranged on inclined pipeline, because the sealed direction of direction and large and small steam vent requirement of buoyancy is inconsistent, and lead
To bar and pilot hole（Groove）Between and floating body and floating-body cover endoporus between there is gap, therefore when lifting cover or floating body are made in buoyancy
Necessarily occur when the position with large and small vent hole seal is risen under ' crooked ', causing to seal, and cause leak；When
When the Dou degree that inclines is larger, due to by unilateral friction, or even lifting cover or floating body can be caused not dead in respective aperture.Therefore national standard is advised
Determine 2 ° of the installation gradient ＜ of ordinary vent valve, but in actual use, the situation on tilted tube be it is very universal,
Rise or fall pipeline section without break for long range, professional etiquette requirement every（0.1—0.8）KM sets an air bleeding valve, it is clear that
Ordinary vent valve is inapplicable； 2）Due to being full water in the operating condition, in valve, therefore water hammer-resistant ability, after valve
Stop valve quick closedown or when water-filling big air bleeding valve quick closedown moment produces water hammer first, easily cause ball float equal strength compared with
The damage of weak part；3）Always there is a small amount of moisture to be carried over when large and small steam vent is vented, these moisture are accumulated in above lifting cover
Big steam vent in, if long-term accumulate and the two can be made to be consolidated because of corrosion, so as to influence the action of lifting cover, or work as pipeline
Pipeline is inhaled into during interior generation negative pressure and polluted source； 4 ）There is no overpressure protection apparatus, when occurring instantaneous superpressure in valve, make
Damaged into valve body piece.

Ensure the outer rim of the seal closure when not intaking in the following following of exhausting window j with the relative position of guide rod, in order to avoid influence row
Gas.
Operation principle
When anhydrous in valve（Fig. 1）, ball float 17 is positioned at the bottom of ball float cover 18, and lifting cover 16 is in extreme lower position.When first
Or when being supplied water again into pipeline after pipe-line system maintenance, substantial amounts of air is empty by water inlet a, inlet opening b, annular in pipeline
The H of air cavity two2, exhausting window j enter ball float cover 18 in, then pass through big steam vent k, discharge chamber H3And exhaust outlet m is quickly outwards arranged
Go out.After water is full of in pipeline, water enters air bleeding valve by water inlet a, inlet opening b, in the H of annular air chamber two2It is middle to rise.
Due to the H of annular air chamber one1It is open downwards, Qi Xiakou is raised to when waterborne（That is hole C top）When, the H of annular air chamber one1
As a closed air chamber, therefore water will not enter, so foring certain thickness and volume in the periphery of air bleeding valve
Annular air layer；Water enters the bottom of ball float cover 18 by aperture d of intaking simultaneously, and ball float 17 rises under buoyancy, and band
Dynamic lifting cover 16 rises, until the seal closure of lifting cover 16 is contacted with sealing gasket 1, and by big steam vent k under buoyancy
Closing, water-tight, the H of moment annular air chamber two before closing2In air also drained, and allow to have a small amount of water from big steam vent
Discharged in k；Simultaneously under buoyancy, the sealing gasket 2 15 of the top of ball float 17 closes small de-air hole h, water-tight, now,
Quick air-discharge terminates（Fig. 2）.Terminate when Quick air-discharge, water-filling is completed and after large and small vent closure, the lower section of lifting cover 16 is still
Nonresident portion air, this partial air is closed, and with certain pressure, therefore in normal water supply situation, big steam vent k
It will not open.In water supply process, with the change of temperature and pressure, the air in water is released, and to ball float
17 tops, the Spatial Agglomeration of the lower section of lifting cover 16, air pressure are constantly raised, water level decreasing in valve, and buoyancy suffered by ball float 17 is also therewith
Reduction, when the weight of ball float 17 exceedes suffered buoyancy and small de-air hole h because of upwards thrust sum suffered by inside and outside differential pressure,
Ball float 17 declines, and small de-air hole h is opened, and the body of calming the anger of the top of ball float 17 is outside by small de-air hole h and radial hole g
Discharge；After body of calming the anger discharge, water level is raised in valve, and ball float 17 rises, again closes small de-air hole h, so follow repeatedly
Ring.
When the impact of water hammer ripple that downstream is produced reaches air bleeding valve, due to the H of annular air chamber one1In air layer be bullet
Property body,
Therefore shock wave can be absorbed, prevents water hammer damage air bleeding valve；In addition, air layer has function of heat insulation, it can prevent
Expanded and spalling valve body because water-ice freezes.
When hydraulic pressure exceedes setting value in valve, water under high pressure by the e of relief hole one overcome the pressure of spring 23 by flap 21 to
Outside
Promote, safety valve is opened, and water under high pressure is through intermediate cavity H4Discharged from the f of relief hole two, it is therefore prevented that superpressure it is broken
It is bad.
Produce water level in negative pressure, valve when pipe drainage, in pipeline to decline rapidly, ball float 17 falls back to the bottom of ball float cover 18
Portion, lifting cover 16 falls back to minimum point, and big steam vent k is opened, opposite order when outside air is by with exhaust
The tonifying Qi into pipeline, it is therefore prevented that pipeline is damaged because of negative pressure.
Install
When dispatching from the factory, the position of each part of air bleeding valve is as shown in figure 1, the now center line 0 of air bleeding valve1--01With valve component
's
Center line 02-02Unanimously, when on tilted tube, on pipeline and valve seat is ensured first by whole machine installation
Component center line 02-02Substantially perpendicular to water-tight at pipe centerline and faying face；Then, regulating bolt 7 etc. is unscrewed, is solved
Fixation except gland 6, pressure ring 5 and support ring 2 to air bleeding valve；Then, by the center line 0 of air bleeding valve1-01Adjust to vertical position
Put；Regulating bolt 7 etc. is finally screwed, by the center line 0 of air bleeding valve1-01It is fixed on upright position.
The utility model can be arranged on the pipeline of gradient≤20 °.
