Description

Internal water-gas double-cooling and heating expansion head flaring device for PVC-O pipe

Technical Field

The utility model relates to a relevant technical field of tubular product production particularly, relates to a PVC-O tubular product is with inside aqueous vapor double cooling and heating inflation head flaring device.

Background

At present, flaring expansion heads used in domestic PVC-O pipe production lines do not have internal heating and cooling devices, and the temperature of the expansion heads is too low during startup, so that startup production is not facilitated; the inside temperature of expansion head is under high by the heat-conduction of hot tubular product temperature in the production process, all is leading to the mode that reduces production speed and outside cooling more in order to reach the purpose that makes flaring expansion head temperature reduce, greatly reduced production speed, the unusual condition often appears in the production process moreover, can not stabilize efficient production in succession, wastes time and energy, and working strength is big.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned technical problem among the correlation technique, the utility model provides a PVC-O tubular product is with inside aqueous vapor double cooling and heating inflation head flaring device can overcome prior art's the aforesaid not enough.

In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:

the internal water-gas double-cooling and heating expansion head flaring device for the PVC-O pipe comprises a shell, wherein a mold core is arranged in the shell, an air cavity is formed between the shell and the mold core, one end of the shell is connected with an air inlet pipe communicated with the air cavity, a plurality of air holes communicated with the air cavity are formed in the surface of the shell, a heating wire is arranged on the side wall of the inner side of the shell, a water-cooling pipe is wound on the mold core, and the two ends of the water-cooling pipe extend out of the shell towards one end, far away from the air.

Furthermore, the air inlet pipe and the water cooling pipe are seamless steel pipes.

Furthermore, both ends of the water-cooling pipe comprise a cooling water inlet and a cooling water outlet.

The utility model has the advantages that: the temperature of the expansion head is ensured by the heating wire during starting, so that the quick starting production is facilitated, and meanwhile, the quick cooling after the internal temperature of the expansion head is conducted by the temperature of the hot pipe in the production process is realized by the structures of the air inlet pipe and the water cooling pipe; the starting efficiency is improved, the waste material cost and the labor intensity of workers are reduced, and the continuous production of production is ensured.
