Background technique
At present, in some sealing girths long (several meters to hundreds of rice), sealing out-of-shape (curve or straight line), the cold and hot pressure of environment changes occasion greatly, can use gas-flow closure.This seal ring utilizes the flexible nature of rubber itself, is hidden in groove when normality, and curve deformation occurs when inflation, and intermediate portion outwards bulges, and with another sealing surface close contact, reaches sealing.This sealing means can effectively overcome the skimble-scamble situation of seal clearance, makes sealing not be subject to the impact of processing length and assembly precision, and also has the advantage of long service life, convenient disassembly and minimizing installation procedure.
Traditional gas-flow closure circle is arranged in groove, and in the time that needs open the door, seal ring is deflated to normal pressure, and rubber retraction, departs from completely with sealing contact surface, like this, in the time tangentially pulling open chamber door or tank body, is unlikely damaged.But, in actual applications, because rubber is worked in the environment in High Temperature High Pressure or low-temp low-pressure for a long time, for several times, just there is rubber elasticity deficiency, after venting, can not be retracted to the phenomenon in groove completely, now, at the drop-down unpacking door of the unwitting situation of staff, will cause seal ring to damage.
Model utility content
The technical problems to be solved in the utility model is: for the deficiency of prior art existence, provide a kind of gas-flow closure coil assembly of long service life.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of gas-flow closure coil assembly, the loading line and the bleed line that comprise gas-flow closure circle and be connected with the air bag of gas-flow closure circle, described loading line is provided with inflation on-off valve, described bleed line is provided with venting on-off valve, described loading line connects source of compressed air, and described bleed line connects air extractor.
Further improvement as technique scheme:
Described loading line is connected with described air bag by common main line with bleed line, and described main line is provided with pressure gauge.
Described pressure gauge by controller with air extractor or/and inflation on-off valve signal be connected.
Described loading line is provided with safety check.
Described inflation on-off valve and venting on-off valve are solenoid valve.
Compared with prior art, the utility model has the advantage of:
1, the utility model is provided with air extractor, when gas-flow closure circle venting release, bleed by air extractor, make formation negative pressure in gas-flow closure circle air bag, gas-flow closure circle shrinks under suction function, can be absorbed in completely in groove, prevent from damaging gas-flow closure circle in the time pulling open sealing surface, thereby improve gas-flow closure circle working life.
2, the utility model can be monitored the pressure in main line by pressure gauge in the time of venting release, and restarts air extractor in the time that pressure gauge detects that pressure is normal pressure, can prevent that air extractor from damaging.
3, the utility model can be monitored the pressure in main line by pressure gauge in the time of gas-flow closure, can monitor whether gas-flow closure circle is inflated successfully, and protection gas-flow closure circle does not burst because pressure is excessive.
4, the utility model is provided with safety check on loading line, and can prevent source of compressed air because of power-off or other fault stop supplies time, gas-flow closure circle is inflated unsuccessfully.

Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; should be understood that; protection domain of the present utility model is also not only confined to following embodiment; for those skilled in the art; in the some improvements and modifications that do not depart under the utility model principle prerequisite, also should be considered as protection domain of the present utility model.
As shown in Figure 1, gas-flow closure coil assembly of the present utility model, the loading line 3 and the bleed line 4 that comprise gas-flow closure circle 1 and be connected with the air bag 2 of gas-flow closure circle 1, gas-flow closure circle 1 is installed in mounting groove 13.Loading line 3 is provided with inflation on-off valve 5, and bleed line 4 is provided with venting on-off valve 6, and inflation on-off valve 5 and venting on-off valve 6 are solenoid valve.Loading line 3 connects source of compressed air 7, and bleed line 4 connects air extractor 8.Referring to Fig. 2, when gas-flow closure circle 1 is exitted release, bleed by air extractor 8, make the interior formation negative pressure of gas-flow closure circle 1 air bag 2, gas-flow closure circle 1 shrinks under suction function, can be absorbed in completely in mounting groove 13, prevent from damaging gas-flow closure circle 1 in the time pulling open sealing surface, thereby improve the working life of gas-flow closure circle 1.
In the present embodiment, loading line 3 is connected with air bag 2 by common main line 9 with bleed line 4, main line 9 is provided with pressure gauge 10, pressure gauge 10 is connected with air extractor 8 and inflation on-off valve 5 signals by controller 11, and controller 11 is also connected (referring to Fig. 3) with venting on-off valve 6 and upper-position unit 14.Pressure gauge 10 is used for monitoring the pressure on main line 9, and controller 11 is used for controlling the switch of air extractor 8, inflation on-off valve 5 and venting on-off valve 6, realizes closed loop control.
Referring to Fig. 5, when gas-flow closure circle 1 is exitted release, inflation on-off valve 5 is closed, and venting on-off valve 6 is opened, and the interior too much gas discharging of gas-flow closure circle 1 is to bleed line 4.When pressure gauge 10 detects that the pressure in main line 9 is normal pressure, send a signal to controller 11, control air extractor 8 by controller 11 and start, gas-flow closure circle 1 is found time.In the time that gas-flow closure circle 1 is vented to main line 9 for normal pressure, restart air extractor 8, can prevent that air extractor 8 from damaging.
Referring to Fig. 4, in the time of needs gas-flow closure, inflation on-off valve 5 is opened, and venting on-off valve 6 is closed, and pressurized air enters in gas-flow closure circle 1, and gas-flow closure circle 1 air bag 2 pressure increase, and gas-flow closure circle 1 expands, and implements sealing; Now pressure gauge 10 is monitored the pressure of main line 9 always, if pressure maintains elevated pressures, not gas leakage of gas-flow closure circle 1 is described, seals successfully; Exceed if force value is elevated to suddenly the pressure that gas-flow closure circle 1 can bear, close immediately inflation on-off valve 5, protection gas-flow closure circle 1.
In the present embodiment, loading line 3 is provided with safety check 12.If due to power failure, cause pressurized air under-supply, safety check 12 can prevent that the gas in gas-flow closure circle 1 from getting back in loading line 3, guarantees that sealing load does not decline, and ensures to seal successfully.
