By using above-mentioned technical proposal, the steam flow of the second insulating tube and the first insulating tube is on the contrary, form convection current
Mode, it is ensured that the medium channel at valve body both ends can obtain uniform heat, avoid steaming caused by steam one-way flow
Vapour outlet side, vapor (steam) temperature is inadequate, and the phenomenon for not reaching heat insulation effect occurs.
Further, the outer wall of the medium channel is provided with spiral depressed part, the depressed part and the first insulation
Pipe, the second insulating tube correspond respectively.
By using above-mentioned technical proposal, the design of depressed part, the amount that steam is passed through internal jacket can be improved, is improved simultaneously
The contact area of steam and medium channel, the efficiency of heat transfer is improved, the medium in medium channel is obtained enough heat
Measure keeping temperature.
Further, the bottom of first insulating tube and the second insulating tube is provided with blow-off pipe；
And blow-off pipe is provided with sealing structure.
By using above-mentioned technical proposal, sewage draining exit is designed, can be discharged when overhauling, safeguarding and remain in inner clip
Steam in set, allow internal jacket by further amounts of steam, improve the insulating efficiency of insulation jacket.
The beneficial effects of the utility model are led to by designing spiral helicine first insulating tube and the second insulating tube, water conservancy diversion
The steam entered, ensure that the steam circulation in internal jacket is uniform, ensure the heat insulation effect of insulation jacket.
