Specific embodiment
With reference to the accompanying drawings and examples the utility model is described in further detail：
Communication type bi-directional voltage stabilizing water seal arrangement, including the interior liquid storage cylinder dividing plate 12 for setting and adapter cavity dividing plate 13 be classified as a left side
Side liquid storage cavity 8, transitional cavity 10 and right side liquid storage cavity 9, in the outer upper of left side liquid storage cavity 8 liquidometer mouth is provided with
L4, outer lower portion is provided with liquidometer mouth L1, and the top of left side liquid storage cavity 8 is provided with atmospheric air port 1, and the top of transitional cavity 10 sets
There is a gas access 2, the top of right side liquid storage cavity 9 is provided with liquid inlet 3, the outer upper of right side liquid storage cavity 9 is provided with and liquid level
With high liquidometer mouth L2, the outer lower portion of right side liquid storage cavity 9 is provided with liquidometer mouth L3 with high liquidometer mouth L1 meter mouth L4,
Liquid outlet 4 is provided with the middle and lower part of right side liquid storage cavity 9 and sewage draining exit 5 is constituted.
The floor space of left side liquid storage cavity 8 is equal with the floor space of right side liquid storage cavity 9, and the width phase of liquid storage cavity
Deng.
In communicating pipe 7 of the bottom of adapter cavity dividing plate 13 equipped with liquid storage cavity 8 and right side liquid storage cavity 9 on the left of connection, mistake
Cross the upper orifice of the top of chamber dividing plate 13 equipped with connection left side liquid storage cavity 8 and the first communicating pipe 6 of right side liquid storage cavity 9.
Communicating pipe 7, the position on transitional cavity 10 determined by the position of liquid outlet 4.I.e.：Original state sets liquid
The gauge pressure of body outlet 4 is 0, and it is P that design requirement maintains maximum gauge pressuremax, in the case of maximum gauge pressure, the height of liquid outlet 4 is arrived
The distance of communicating pipe 7 is H1, according to formula：P=P0+ρLiquid.g.2H1=P0+Pmax,
The height of communicating pipe 7 bears height of the pressure with liquid outlet 4 away from inner bottom surface and determines by the highest of device；First connects
The position of siphunculus 6 determines by the position of communicating pipe 7, i.e. the spacing of communicating pipe 6 H1-H2=communicating pipes 7 and first.
Upper orifice of the top of liquid storage cylinder dividing plate 12 equipped with the second communicating pipe 11 connected with right side liquid storage cavity 9, lower part
The lower nozzle of the second communicating pipe 11 that Zhuan You do not connected with right side liquid storage cavity 9 and communicating pipe 7.
Before and after device goes into operation, the valve of atmospheric air port 1 is constantly in opening, before device goes into operation, by the He of liquid inlet 3
The valve of liquid outlet 4 is opened, and when the water for adding overflows from liquid outlet 4, liquid inlet 3 and outlet valve is closed successively.
Due to the presence of communicating pipe 7 when starting to inject water, left side liquid storage cavity 8 is identical with the liquid level of right side liquid storage cavity 9.
After device goes into operation, when the pressure rise of gas access 2, the liquid level of right side liquid storage cavity 9 can be gradually reduced, and decline
Liquid level left side liquid storage cavity 8 is entered by communicating pipe 7；When hypertonia, the gas in right side liquid storage cavity 9 can be by the
Two communicating pipes 11 released from the atmospheric air port 1 on the top of left side liquid storage cavity 8.Liquid level during reduced pressure in left side liquid storage cavity 8
Automatically right side liquid storage can be entered by the first communicating pipe 6.
When the pressure in right side liquid storage cavity 9 is negative pressure, the liquid in left chamber body 8 can be passed through first by extraneous air
On the right side of the press-in of communicating pipe 6 in liquid storage cavity 9；When hypotony, the air in the liquid storage cylinder body of left side can pass through for the first communicating pipe 6
Into in right side liquid storage cavity 9, prevent tank body from deforming.When pressure rise, the liquid of right side liquid storage cavity 9 can automatically pass through
Enter left side liquid storage cavity 8 second communicating pipe 11, prevent gas from escaping air, pollute environment.
If device go into operation after two liquidometers liquid level sum be less than 2H1, the valve addition liquid of liquid inlet can be opened
Body, until the height of two liquidometers and equal to 2H1。
When the maximum pressure in system exceedes setting pressure, the liquid energy of the reduction in right side liquid storage cavity 9 is should ensure that
H in liquid storage cavity 8 on the left of enough by being stored in the second communicating pipe 73>H1, while need to ensure that gas can be by the He of the second communicating pipe 7
Atmospheric air port 1 is released.
When the minimum pressure in system is less than setting setting pressure, the liquid reduced in left side liquid storage cavity 8 is should ensure that
In can be by being stored in right side liquid storage cavity 9 communicating pipe 7, H4>H2, while need to ensure that air can pass through atmosphere entry 1, pass through
First communicating pipe 6 entered right side cavity, prevented tank body from damaging.
Two cavitys of left and right are provided with liquidometer mouth L1, liquidometer mouth L2With liquidometer mouth L3, liquidometer mouth L4, should ensure that liquid level
Meter mouth L1, liquidometer mouth L3In same level；To make the height of water level during pressure oscillation in normal fluctuation range, just
In the case of often, the liquid level sum of two liquidometers is equal to 2H1.If device longtime running, because evaporation can cause the part of liquid
Loss, can be determined whether by the liquid make-up of liquid inlet 3 by observing the liquid level of two liquidometers.
