Fig. 2 be Fig. 1 shown in three hole air bleeding valves in part A close-up schematic view.
Embodiment
The structure and utility model content of three hole of the present utility model air bleeding valve are described with reference to Fig. 1 and 2.
As shown in figure 1, a kind of three hole air bleeding valves, including valve body 1, the bonnet 2 above valve body 1, installed in bonnet 2
The valve bonnet 3 of top, the micro-exhaust valve 4 connected on valve body 1 and with valve body 1 and the high speed being arranged on inside valve body 1
Inlet valve and high-speed exhaust valve.
The valve body 1 is provided with underlying water inlet 5 and the connecting hole 6 positioned at side.The valve body 1 and bonnet 2
Between be connected by some screw elements.
The bonnet 2 is provided with through hole that is above and being connected with valve inner.
The valve bonnet 3 is fixed on the top of bonnet 2 by some connection members.It is provided with and hangs in one of connection member
Button.The valve bonnet 3 is communicated with the inside and outside passage 7 of valve body 1 and bonnet 2.
The high-speed suction valve includes being arranged on the air entry 8 inside valve body 1 and flap 9, the installation of the cooperation of air entry 8
The first valve seat 10 inside bonnet 2, the first sealing ring 11 on the first valve seat 10 and the elastic portion for supporting flap 9
Part 12.The air entry 8 is arranged on the first valve seat 10.The sealing ring 11 of flap 9 and first sealing coordinates.The elastic portion
12 preferred spring of part.
The high-speed exhaust valve includes the exhaust outlet 13 and exhaust outlet 13 for being arranged on the inside of valve body 1 and being arranged on flap 9
Seal the ball float 14 coordinated, the supporting plate 15 for being arranged on the inside of valve body 1 and support ball float 14, the exhaust outlet 13 installed in flap 9
On the second valve seat 16 and the second sealing ring 17 on the second valve seat 16.The ball float 14 and the second sealing ring 17 are close
Envelope coordinates.The lower section of ball float 14 is provided through the guide bar 18 of supporting plate 15.The guide bar 18 can control ball float 14
The direction of motion.The supporting plate 15 includes the supporter and some ribs of connection supporter and valve inner of support ball float 14
Portion.The supporter is provided with the perforation passed through for guide bar 18.
The flap 9 is the core control part of high-speed suction valve；Exhaust outlet 13 on the flap 9 is again high speed exhaust
The core control part of valve.The utility model integrates high-speed suction valve and high-speed exhaust valve, not only reduces three holes
The overall volume of air bleeding valve, respective function also is ensure that simultaneously, realizes high-speed suction and exhaust.
The ball float 14 is connected with the energy movable self-locking of flap 9.Preferred embodiment of the present utility model：The high-speed exhaust valve
Also include the magnetic latching member being arranged on flap 9 and be arranged on ball float 14 and coordinate with magnetic latching member magnetic
Fixture 19.The magnetic latching member includes the support 20 being arranged on flap 9, the groove 21 being arranged on support, placement
Magnet 22 in groove 21, the pressing plate 23 for covering above magnet 22 and coordinating with support 20 and on pressing plate 23 and energy
The flexible release link 24 of opposed magnet 22.The fixture 19 is bolted on ball float 14 into T fonts.The fixture
19 using the material that can be adsorbed by magnet 22.The support 20 is bolted on flap 9.The release link 24 passes through valve bonnet
3 and it is connected through a screw thread and is fixed on pressing plate 23.So after high speed exhaust valve exhaust terminates, the in-line medium of ball float 14 floats
Power effect is lower to be risen；Both self-lockings connections close to magnet 22 and in the presence of magnetic force of the fixture 19 of ball float 14, now ball float
14 and second sealing ring 17 sealing coordinate.When high-speed suction valve starts air-breathing, high-speed exhaust valve will not initiative exhaust.If
When needing the high-speed exhaust valve to start exhaust, as long as by the screw thread transmission of release link 24 and pressing plate 23, release link 24 declines will
The fixture 19 of ball float 14 and magnet 22 are separated, you can to start to be vented.
The cross section l-shaped of the sealing ring 17 of first sealing ring 11 and second, both are hung upside down in the first valve seat respectively
10 and second on valve seat 16.The free end of first sealing ring 11 and the second sealing ring 17 each extends over out the first valve seat 10 and second
The bottom surface of valve seat 10.So flap 9 of the present utility model and ball float 14 are soft or hard dual-seals, sealing property is improved.
The elastomeric element 12 is compressed between supporting plate 15 and flap 9.The lower section of flap 9 is arranged with annular groove.Institute
State the mounting bracket 25 for being provided with supporting plate 15 and surrounding ball float 14.Described one end of elastomeric element 12 is positioned in annular groove；It is another
End is set on mounting bracket 25.The ball float 14 can freely up and down float inside mounting bracket 25.During original state, flap 9 is
It is pressed on by elastomeric element 12 on the first valve seat 10 and the first sealing ring 11 and forms sealing.Due to the pressure of the elastomeric element 12 of compression
The gravity for all parts that contracting power can balance the gravity of flap 9 and ball float 14 itself and both are set above, so this reality
It is not more than 2KPa with the Opening pressure of new flap 9.High-speed suction valve of the present utility model can be opened quickly, be not in
The situation of delay, protect the normal operation of pipeline.
The connecting hole 6 is provided with positioned at the lower section of supporting plate 15.It is provided between the micro-exhaust valve 4 and connecting hole 6 some
The connector 26 of interconnection.Detection ball valve 27 is installed on one of connector 26.The bottom of the micro-exhaust valve 4 is also
It is connected to by connecting plate 28 on bonnet 2.Described one end of connecting plate 28 is connected between micro-exhaust valve 4 and connector 26；Institute
The other end of connecting plate 28 is stated to be connected between bonnet 2 and screw element.The connecting plate 28 is for reinforcing micro-exhaust valve 4.
The operation principle of three hole of the present utility model air bleeding valve is as follows：
1. pipeline water flowing at initial stage, the exhaust outlet 13 in three hole air bleeding valves is in the open position, and now the air in pipeline is big
Amount is discharged from exhaust outlet 13, and when the air in pipeline is drained, the water in pipeline enters valve body 1, and ball float 14 is under buoyancy
Rise, close exhaust outlet 13, now ball float 14 is self-locking on the flap 9 of high-speed suction valve by magnetic self-locking part；
2. during pipeline normal operation, micro-exhaust valve 4 constantly continuously discharges the air separated out in pipeline, it is ensured that pipeline
In will not assemble air, influence water delivery；
3. when system is cut off the water or closes valve, there is negative pressure in pipeline, and flap 9 quickly opens tonifying Qi, now because the quilt of ball float 14
It is locked on flap 9, is acted together with flap 9, flap 9 fully opens tonifying Qi, quickly eliminates pipe negative pressure；
4th, when pipeline switchs to malleation by negative pressure, flap 9 is closed, and the air of suction is retained in the duct, can only be passed through
Micro-exhaust valve is slowly discharged, and the air now retained turns into the elastomer in pipeline, and caused water hammer passes through this in pipeline
The volume variability of elastomer is received, and so as to eliminate the generation of water hammer appreciation, effectively protects pipeline.
In summary, preferred embodiment of the present utility model is these are only, should not be limited with this of the present utility model
Scope.I.e. every simple equivalent changes and modifications made according to the utility model claims book and description, all should
Still belong in the range of the utility model patent covers.
