Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, but not as the limitation of the invention.
Fig. 1 is a kind of schematic diagram of high-order Flexible element of the invention.
It is shown in Figure 1, show a kind of preferred embodiment, a kind of high position Flexible element, including
The intake-outlet 11 of vacuum tank 1, vacuum tank 1 is connected with the top of building water supply standpipe 10.
Exhaust valve 2, exhaust valve 2 are set at the intake-outlet 11 of vacuum tank 1.
Tonifying Qi metering device, tonifying Qi metering device are set to the bottom of vacuum tank 1；The lower end surface of tonifying Qi metering device passes through
Several columns 4 are connected on pedestal 5.
Inflating port 6, inflating port 6 are set to the side of vacuum tank 1.
Pressure sensor 7, pressure sensor 7 are set to the side of intake-outlet 11；Pressure sensor 7 is connected to pressure
Table 71.
The above is only preferred embodiments of the present invention, are not intended to limit the implementation manners and the protection scope of the present invention.
Further, in a kind of preferred embodiment, exhaust valve 2 avoids producing in operational process for the air in evacuated tube
Raw biggish water damage and generation water hammer effect, the gas that also can avoid in pipeline are entered in vacuum tank 1, are reduced in vacuum tank 1
The storage capacity of water.
Further, in a kind of preferred embodiment, tonifying Qi metering device includes weighing device and display device 32；Weighing
Device is set to pallet apparatus 31, and pallet apparatus 31 is set on several columns 4；Weighing device is electrically connected to display device 32.
Further, in a kind of preferred embodiment, weighing device is provided with a kind of piezoelectric transducer, can will be under pressure
It is converted directly into weight.
Further, in a kind of preferred embodiment, inflating port 6 is provided with solenoid valve, solenoid valve be electrically connected weighing device and
Pressure sensor 7.When the value that weighing device measures be greater than tank body self weight and the density of 0.6V* water and, then pass through opening electromagnetism
Valve is inflated vacuum tank 1.
In addition, the entire inflation logic of vacuum tank 1 can by be arranged PLC program, solenoid valve carry out automation inflation or
It can be inflated manually to scene according to field instrument with operator.
Further, in a kind of preferred embodiment, pressure gauge 71 is set to the upper surface of vacuum tank 1.
Further, in a kind of preferred embodiment, tonifying Qi metering device further includes having alarm device；Alarm device electrical connection
Weighing device.
In addition to the implementation, the present invention also has following working method:
Rubber bag tank (not shown) is provided in vacuum tank 1 first, rubber bag tank stroke is limited, it is therefore necessary to fill in advance
A part of gas, avoids rubber bag tank from cracking；Preliminary pressure-filled is generally 0.4 times of operating pressure, and 1 volume of vacuum tank is V；It is practical
Operating pressure is assumed to 0.1MPa, the general top that standpipe is arranged.
When normal, 1 internal volume of vacuum tank is V1, operating pressure 0.1MPa；1 inside gas of vacuum tank after work
Body volume is V2 (equal to the volume V of vacuum tank 1), and operating pressure is P2=0.04MPa at this time；
Therefore according to law P1V1=P2V2, V1=0.4V can be obtained；
It is V-V1=0.6V that the i.e. interior volume of water storage of compensation rate, which is then calculated,；
Can obtain: the weight of water storage is the density (weight of maximum water-storage) of 0.6V* water.
Therefore, if the weighing device of tonifying Qi metering device measures weight greater than tank body self weight and the density of 0.6V* water
With, that is, say 1 air pressure inside pressure of vacuum tank decline so that water inlet exceed reservoir storage.
Therefore intake pressure need to be observed using intake-outlet 11, if intake pressure is maintained at 0.1MPa for a long time, illustrated steady
Press 1 internal pressure of tank balance, observation weighing device measures at this time weight value whether be tank body self weight and 0.6V* water density
With；If weight is greater than the numerical value, vacuum tank 1 is inflated, until the weight value that weighing device measures is equal to the value.
The above is only preferred embodiments of the present invention, are not intended to limit the implementation manners and the protection scope of the present invention, right
For those skilled in the art, it should can appreciate that and all replace with being equal made by description of the invention and diagramatic content
It changes and obviously changes obtained scheme, should all be included within the scope of the present invention.
