The pneumatic balanced structure of air pressure；Housing 1 has water inlet end and discharge ends, and the water inlet end of housing 1 is connected by inlet channel structure 5
The water side of heat exchanger 7, so that the hydrophobic of heat exchanger 7 is delivered in housing 1；The discharge ends of housing 1 is arranged on the bottom surface of housing 1
By communicated drainage pipeline 4, for hydrophobic discharge；Form the self-balance structure of waterpower of ball float 2.
In embodiment, described housing 1 is vertical columnar structured；Inlet channel structure 5 is made up of a water pipe.Described
Outlet 11 is located at the bottom of housing 1, and this outlet 11 is cone, outlet 11 inwall of described ball float 2 and cone it
Between remain with 0～150mm cross water space.Be provided with a ball float pallet 3 in the lower end of outlet 11, this ball float pallet 3 is positioned at floating
The bottom of ball 2, is provided with a circular hole 31 in ball float pallet 3, and described ball float 2 is placed at the circular hole 31 of ball float pallet 3, makes ball float
2, by closing with the clutch for clutch control of circular hole 31 or opening outlet 11, produce buoyancy under the pressure that i.e. ball float 2 is hydrophobic in housing
Rise and produce distance/spacing with circular hole 31, make outlet 11 open, or coincide with circular hole 31 generation when ball float 2 declines, make water outlet
Mouth 11 is closed.
The heater of the present embodiment is shell-and-tube heater, in application, using ball float 2 as execution unit, not by hydrophobic mistake
The impact of cold degree, and with static balance as principle, can autobalance specify on position with water level in keeping heater.
During use, housing 1 inner chamber is as ball float 2 and soda pop cushion space, and ball float 2 arranges at the outlet 11 of housing 1,
Concrete, ball float 2 is positioned at the outlet 11 of cone, utilizes ball float pallet 3 to hold up, makes to remain with 0 between ball float 2 and inwall
～the gap of 150mm.Allow the most hydrophobic to be introduced into ball float bottom.When, after hydrophobic entrance housing 1, ball float 2 is in the hydrophobic amount of housing 1
Increasing, rise under effect that buoyancy increases, what ball float 2 and inwall produced water space increases therewith, makes ball float 2 and ball float pallet
The circular hole 31 of 3 produces distance, opens outlet 11, can allow hydrophobic flowing downward out；Owing to outlet 11 inwall of ball float 2 position is
Taper, ball float 2 levitation height is the highest, and the gap between inwall is the biggest, and hydrophobic through-flow of annular the biggest, therefore ball float 2 with
Housing conical water outlet 11 coordinates and has just possessed the function being automatically adjusted flow area with hydrophobic amount size, and ball float 2 rises and leaves
Time at conical water outlet 11, through-current capability reaches maximum.Meanwhile, cooperate at ball float 2 and housing 1 and possess hydrophobic flow quantity self-adjusting
Joint function, can avoid ball float under the hydrophobic operating mode of low discharge to frequently switch on and cause wear damage, it is also possible to reduce sending out of water attack
Raw possible, strengthen serviceability and the expanded service life of ball float.
Described ball float 2 is the critical component of self-balancing steam trap connection, is a precision machined hollow ball, its spheroid
Global density is less than hydrophobic spheroid, and ball float 2 is arranged at the conical water outlet 11 of housing 1, as closing element and flow
Adjusting means, when hydrophobic entrance housing, ball float 2 floats opens outlet 11, and when hydrophobic minimizing or stopping, ball float 2 falls
Lower closedown outlet.
Described ball float pallet 3 be one piece of arcwall face be the fixed plate of up concave type, described circular hole 31 is located at recessed lowest order
Place.Ball float pallet 3 both as the support face of ball float 2, also served as sealing surface.When not having hydrophobic, ball float 2 is not by buoyancy, at weight
Power effect drops to lowest order and closes circular hole 31, and this circular hole is open hole, ball float 2 and circular hole 31 limit of ball float pallet 3
Edge tightly combines, and is now in closed mode, and steam will not leak；When hydrophobic entrance, ball float 2 rises under buoyancy,
Turn on sealing surface (i.e. opening circular hole on ball float pallet 3), be now opening, hydrophobic timely discharge.
Described drainage pipeline 4 is connected with housing 1 lowest order, makes hydrophobic to drain into downstream.The internal diameter of drainage pipeline 4 is dredged with maximum
The water yield is correlated with, and can obtain drainage pipeline internal diameter according to hydrophobic volumetric flow rate 0.5～1m/s inverse.
Described inlet channel 5 is connected with the middle part of housing 1, the internal diameter of inlet channel 5 can by hydrophobic volumetric flow rate 1～
2m/s calculates, if pipeline is shorter, it is also possible to exceed this flow velocity.This inlet channel 5 and heat exchanger 7 connectivity part are less than normal
Liquid level is arranged, may remain in the water suction of below liquid level, it is to avoid suck the foam on liquid level or gas, it is to avoid produce gas-liquid in pipeline
Two phase flow and vibrate.
Inlet channel 5 has carried out particular design to realize two functions: utilize fluid pressure equilibrium principle, inlet channel 5
Entering housing 1 position contour with normal level level, (described liquid level is hydrophobic with gas equalizing main 6 synergy, only liquid level
Height and position) can discharge higher than the hydrophobic of normal level line, hydrophobic under fluid pressure effect less than normal level line
Can not discharge, it is ensured that the liquid level equilibrium within heat exchanger 7.In order to avoid sucking foam or the gas of ullage, with heating
One end that device 7 connects is less than normal level line (as shown in labelling h in Fig. 1), and h is typically by 10～50mm considerations.Make inlet channel 5
Foam and the gas of ullage will not be sucked, biphase gas and liquid flow will not be produced, therefore, pipe vibration would not be caused and make an uproar
Sound.
Described gas equalizing main 6 connects with heat exchanger 7 upper gas space, makes the air pressure of housing 1 communicate with heat exchanger 7,
In avoiding heat exchanger 7, pressure is crushed to death much larger than ball float during drainage pipeline 4 outlet pressure, and in also avoiding housing 1, gas can not be arranged
Go out and cause " vent plug ".Destroy the siphonic effect of inlet channel 5 with seasonal epidemic pathogens equalizing main 6, it is hydrophobic that this makes in heat exchanger 7
The difference in height that can only rely on liquid (the most hydrophobic) self is discharged, less than dredging of inlet channel 5 end (with housing 1 junction) height
Water can not be discharged.
In order to reach more preferably counterbalance effect, described gas equalizing main 6 discharge capacity more than inlet channel 5 1%～10% with
On.Concrete, the internal diameter of gas equalizing main 6 is chosen in proportion with inlet channel 5, and internal diameter ratio preferred value is 1:30～1:50.
The gas equalizing main 6 selecting more large diameter does not affect using effect, but when gas equalizing main 6 internal diameter is less than normal, dredges at big flow
The moment that water and ball float are not switched on is it is possible that circulation is the most smooth.
When described inlet channel 5 is applied with gas equalizing main 6, inlet channel 5 and gas equalizing main 6 control heat exchanger 7
Interior liquid level is at setting position.The height giving inlet channel 5 end during design can be obtained by the design height of normal level,
Or normal level height as requested is with the height of design inlet channel 5 end (i.e. connecting one end of housing 1 position), i.e.
Described inlet channel 5 is adjusted setting liquid level position, water inlet by accessing the relative position between housing 1 and heat exchanger 7
Pipeline 5 accesses that housing 1 position is the highest, and the liquid level of heat exchanger is the highest, gas equalizing main 6 in balance shell body with in heat exchanger 7
Air pressure, make ball float 2 normally float, control outlet 11 air draft hydrophobic.
The hydrophobic flow area computational methods of above-mentioned float-ball type self-balancing steam trap connection, owing to the diameter of ball float goes out with taper
The mouth of a river 11 diameter is association, and hydrophobic flow area is ball float lifting heights and the function of conical water outlet 11 inner diameter,
Can be calculated by the diameter of the section curve of housing with ball float, meet hydrophobic design maximum flow and minimal design simultaneously
The requirement of flow.The function expression of its flow area is:
A=F (dH, H)
dH=f (H)
Q=A × ω
In formula:
The hydrophobic flow area of A, i.e. annulus flow area between ball float and housing
dHAt ball float height and position H, the inner diameter of housing
