Description
What the utility model related to a kind of air pressure speed governing that is used for old lining of pipe line turns over the pipelining device.
Existing old lining of pipe line is with turning over the pipelining device, directly utilize the compressed gas-driven lining flexible pipe of air compressor to advance, make and turn over pipelining speed and the speed shakiness occurs, rest phenomenon, start difficulty after occurring resting once more and improve the backing layer bearing requirements, cost is improved.Existing turn over pipelining device SMIS axial length short non-adjustable, when conversion construction pipeline inconvenience.
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of turn over superior in quality, the easy to operate air pressure speed governing of pipelining velocity-stabilization, lining turn over the pipelining device.
The purpose of this utility model reaches by following measure.
A kind of air pressure speed governing of the present utility model turn over the pipelining device, comprise gas-tight silo 1, mandrel 2 in gas-tight silo 1, the transmission component 3 that is connected with mandrel 2, the liner hose 4 of on mandrel 2, twining, visor 5 on gas-tight silo 1, manhole 6, nipple 7, vapour inlet 8, air inlet 9, it is characterized in that being connected with air pressure speed governing pipeline 10, the safety valve 11 and the Pressure gauge 12 that can communicate with source of the gas arranged at air pressure speed governing pipeline 10 at air inlet 9, with lower edge air pressure speed governing pipeline 10 stop valve 13 is arranged in turn, pressure-reducing valve 14, Pressure gauge 15 and hand-operated direction valve 16 and choke valve 17, the Pressure gauge 18 that communicates with choke valve 17, with choke valve 17, the Pneumatic valve 19 that hand-operated direction valve 16 and Pressure gauge 18 communicate, the rapid escape valve 20 that communicates with Pneumatic valve 19, the Pressure gauge 21 and the safety valve 22 that communicate with rapid escape valve 20 and can communicate with gas-tight silo 1.Liner hose 4 is made by coating unsaturated polyester (UP) in the polyethylene nonwoven flexible pipe preferably, and an end-stopping plate of mandrel 2 is removable along mandrel 2.
Air pressure speed governing of the present utility model turn over the pipelining device, when operation, at first air pressure speed governing pipeline 10 is connected sources of the gas, adjust safety valve 11 maximum gas pressure and reach setting, for example pressure P
1=0.5MPa, can be by Pressure gauge 12 observation, the outlet pressure of adjusting pressure-reducing valve 14 then reaches setting, as pressure P
2=0.35～0.4MPa adjusts choke valve (17) gas flow, reaches certain variation by forward (FWD) requirement adjusting air pressure when the beginning forward (FWD), in beginning preceding half stage of forward (FWD), to big, pressure is controlled at prescribed limit to gas flow, as P by little
3=0～0.35MPa, in the forward (FWD) rear half stage, gas flow from large to small, thereby guarantee forward (FWD) speed evenly, stable, do not produce and rest phenomenon.In the forward (FWD) process, hand-operated direction valve 16 is in obstructed position, Pneumatic valve 19 is in the normal open position, and rapid escape valve 20 communicates with gas-tight silo 1.Press when stopping forward (FWD) that hand-operated direction valve 16 can make that Pneumatic valve 19 resets, the logical atmosphere of gas circuit, this moment rapid escape valve 20 communicate with atmosphere quick exhaust, stop the forward (FWD) operation.The air pressure of safety valve 22 control gas-tight silos 1 is when pressure surpasses setting, as P
4Safety valve 22 is opened and is laid down overpressure during＞0.3MPa.
Air pressure speed governing of the present utility model turn over the pipelining device, liner hose 4 can be made by coating unsaturated polyester (UP) in the linear low density polyethylene (LLDPE) nonwoven flexible pipe, needs to feed in old pipeline steam heated curing liner after.Adopt polyethylene nonwoven flexible pipe that cost is reduced.
Air pressure speed governing of the present utility model turn over the pipelining device because an end-stopping plate of mandrel 2 can move on mandrel 2, the winding width of conversion mandrel 2, thus applicable to the liner operation of different tube diameters.When the liner operation, at first liner hose 4 is wrapped on the mandrel 2, output port with liner hose 4 is fixed on the nipple 7 then, communicate with inner lining old pipe, feeding compressed air rear inner lining flexible pipe 4 in gas-tight silo 1 can drive the old tube wall in lower edge at blast and advance, liner hose 4 nexines adhere on the old tube wall outwardly, when liner hose 4 advances to half length, flexible pipe tail line tension by liner hose 4, at this moment required blast reduces gradually, has all turned over up to whole liner hose 4 to adhere on the old tube wall.Enter heat steam then and make curable unsaturated polyester.
The utility model compared with prior art has following advantage:
1, air pressure speed governing of the present utility model turn over the pipelining device, by air pressure speed governing pipeline control air pressure change, make forward (FWD) speed evenly, stable, guarantee the liner quality, easy to operate, safe and reliable.
2, adopt polyethylene nonwoven flexible pipe to make easy construction, reduce cost.
3, the lining repair of applicable different tube diameters is easy and simple to handle.
