Embodiment
[embodiment 1]
This patent provides a kind of automatic compensating inflation soft seal method with remote control function, soft seal device is adopted to seal between storage tank floating plate and tank skin, described soft seal device mainly comprises air bag, air bag fixing belt, bladder joint, pressed gas storage tank, pressure wireless sensor, gas-injecting pipe, air bag is fixed on floating plate edge, air bag top and bottom are separately fixed at lower end air bag bracket and the floating plate upper edge of floating plate by air bag fixing belt, adjacent two air bags adopt bladder joint to connect, the space between floating plate and tank skin is full of after airbag aeration, each air bag is provided with injecting hole, injecting hole is connected by gas-injecting pipe with pressed gas storage tank, pressed gas storage tank is provided with blowdown pipe and pressure wireless sensor, wherein, described bladder joint internal surface is provided with hangnail with the air bag after fixing inflation.
The length of air bag needed for floating roof tank is determined by storage tank floating plate diameter, and each balloon length gets 18m, is convenient to install and carrying.The girth of air bag longitudinal section depends on the height of floating plate, after airbag aeration, need ensure that the space between floating plate and tank skin is full of completely, and namely after airbag aeration, the height of air bag is equal with floating plate height.Adjacent two air bags adopt annular air-pocket joint to connect, and namely air bag inserts in joint before inflation, and adopt hangnail fixation balloon in joint, joint length is 1000mm; After inflating, air bag and joint are fitted completely, and the hangnail be abutted against in head fixes two air bags.Each air bag arranges a rubber band every 3m, is fixed in floating plate edge.An injecting hole is established at each air bag top, and injecting hole is connected by pneumatic tube with pressed gas storage tank.The gas of certain pressure gas is stored in pressed gas storage tank, and all airbags between this storage tank and floating plate, all air bags carry out respiratory exchange by pressed gas storage tank, realize the integral pressure balance of all air bags of floating plate.Pressed gas storage tank is established pressure wireless sensor, control centre can change by remote monitoring intracapsular pressure, as exceeded predefined value lower than certain setting value or Pressure Drop low speed, then the gas injection port place valve of collecting pipe will be closed, to prevent other airbag gas from also leaking, and in time from the external world to tonifying Qi in pressure vessel.
First according to this storage tank Size calculation floating plate girth and floating plate height, determine the length of required air bag and height, calculate the gentle capsule quantity of institute's air demand.A pressed gas storage tank is set at floating plate center, this storage tank is established gas collecting pipe, pressure gauge, valve and wireless pressure sensor etc., collecting pipe interface quantity is equal with air bag requirement, and each collecting pipe jointing establishes a valve, to close source of the gas when keeping in repair air bag.
After all air bags install bladder joint, the gas-injecting pipe of each air bag is all connected successively with the collecting pipe interface of the gas pressure reservoir at floating plate center, from drawing a tracheae tank to gas injection in pressed gas storage tank, until all air bags fully expand, after storage tank internal air pressure reaches 0.14 ~ 0.16MPa, stop gas injection, and remove extraneous source of the gas, the suction port of closing pressure gas reservoir.After air bag expands, the barb structure close contact in air bag and joint, ensures that whole air bag is linked to be a complete inflator.If certain bladder deflates, then air bag comes off in joint, takes out single air bag.
In use, if certain air bag leaks, then gas reservoir internal pressure will reduce rapidly or slowly reduce, and wait after being reduced to predefined value, and wireless pressure sensor will be reported to the police, the main valve of the mouth of pipe of confluxing cuts out automatically, gas intercommunicating system between each air bag is closed, to ensure intact air bag not gas leakage, now, the air bag leaked is checked and changed, again to tonifying Qi in air bag to predetermined pressure after reparation.
