Description
Technical field
The utility model relates to a kind of automatic hydraulic flange sealer, metal conduit heat-insulation layer manufacturing equipment technical field.
Background technology
At present, in insulating tube process, have an important step to be exactly manufacture to heat-insulation layer, section of tubing heat-insulation layer adopts polyurethane material, implements polyurethane foam.Shutoff flange need be used during foaming operation by the two ends shutoff of the pillar outside of the cavity between steel pipe and outer pillar, because outer pillar is high density polyethylene pipe, there is certain elasticity, therefore the sealing effectiveness of shutoff flange and outer pillar inwall is generally better, interior pipe is steel pipe, when gap between the internal diameter and outer wall of inner tube of shutoff flange is less, the installation of shutoff flange is comparatively difficult, particularly when the interior pipe mouth of pipe has ellipse in critical field or local crowning, the installation of shutoff flange is more difficult, production efficiency is low, when gap between the internal diameter and outer wall of inner tube of shutoff flange is larger, the installation of shutoff flange more for convenience, but polyurethane foam material can be excessive along the gap between shutoff flange inner diameter and outer wall of inner tube during foaming, cause waste of raw materials, heat-insulation layer foam density reduces, be unfavorable for ensureing product quality.Particularly when interior pipe is spiral weld steel pipe, by the shutoff flange that affects of spiral weld, to leak material situation even more serious, reduces product quality, can not reach quality requirement and good heat insulation effect.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned technological deficiency and provides that a kind of structure is simple, easy to operate, good airproof performance, guarantees that steel pipe, flange and outer pillar seamlessly to contact, in heat-insulation layer manufacturing process, guarantee the dead-tight automatic hydraulic flange sealer of urethane raw.
Problem described in the utility model solves with following technical proposals:
A kind of automatic hydraulic flange sealer, comprise base, support, elevating mechanism, clamp system and shutoff flange, it is characterized in that: described shutoff flange is stepped circular flange, described ring flange inner circle coordinates with ligament in insulating tube, described ring flange inner circle circumferentially arranges sealed groove, described sealed groove is built with can radially move and sealing ring friction tight with groove side arm, gap is left bottom described sealing ring and sealed groove, described ring flange outer face arranges the pressure pipeline connecting hole connecting sealed groove bottom of trench
According to described automatic hydraulic flange sealer, described shutoff flange is arranged an access opening be in communication with the outside by foam chamber.
According to described automatic hydraulic flange sealer, described shutoff flange built-in end arranges chamfering.
The beneficial effect that produces of technique scheme is adopted to be: the utility model solves the not tight problem of cavity two ends shutoff in the heat-insulation layer manufacturing process of insulating tube between steel pipe and outer pillar, urethane raw is prevented to reveal, ensure the foam quality of heat-insulation layer, improve heat insulation effect, greatly reduce labor strength simultaneously, save manufacturing cost.

Detailed description of the invention
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of automatic hydraulic flange sealer, comprise base 1, support 2, elevating mechanism 3, clamp system 4 and shutoff flange 5, shutoff flange 5 is stepped circular flange, pipe 6 matched in clearance in ring flange inner circle and insulating tube, make the installation of shutoff flange more for convenience, described ring flange inner circle circumferentially arranges sealed groove 7, described sealed groove 7 is built with can radially move and sealing ring 8 friction tight with groove side arm, gap 9 is left bottom described sealing ring 8 and sealed groove 7, described ring flange outer face arranges the pressure pipeline connecting hole 10 connecting sealed groove bottom of trench, during use, hydraulic oil is pressed in people gap 9 by pressure pipeline connecting hole 10, sealing ring 8 is moved radially along sealed groove 7, sealing ring 8 to be tightly pressed in insulating tube on pipe 6, in heat-insulation layer manufacturing process, guarantee that urethane raw is without leakage.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of automatic hydraulic flange sealer, described shutoff flange is arranged an access opening 12 be in communication with the outside by foam chamber 11.During use, urethane raw is injected by the access opening 12 of side shutoff flange 5, and the excessive gas in foam chamber 11 is got rid of by the access opening 12 of opposite side shutoff flange 5, make heat-insulation layer even density, end fill enrich.
Referring to Fig. 1, Fig. 3, Fig. 4, a kind of automatic hydraulic flange sealer, described shutoff flange 5 built-in end arranges chamfering 13.Facilitate shutoff flange 5 by the two ends shutoff of the pillar outside of the cavity between steel pipe and outer pillar during foaming operation.
Utility model works process is as follows, opening two ends clamp system 4 is bumped between steel pipe and outer pillar by shutoff flange 5, hydraulic oil is pressed in people gap 9 by pressure pipeline connecting hole 10, sealing ring 8 is moved radially along sealed groove 7, sealing ring 8 is tightly pressed on steel pipe 6, when foaming, urethane raw is injected by the access opening 12 of side shutoff flange 5, excessive gas in foam chamber 11 is got rid of by the access opening 12 of opposite side shutoff flange 5, make heat-insulation layer even density, end is filled and is enriched, after foaming, with hoisting apparatus, finished product is taken out, prepare next workflow.
