Techniques presented herein relate to vulcanizing equipment that includes a vulcanizing mold in which a vulcanizing cavity is formed, a vulcanizing bladder suitable for being placed in the vulcanizing cavity, and a supporting assembly that includes a center rod and a clamping device arranged on the center rod. The clamping device is suitable for installing the curing bladder in the cavity in a sealed manner. The vulcanizing equipment further includes a heating assembly and a gas circulation assembly that are arranged in the curing bladder in a stacked manner in the axial direction of the center rod. The gas circulation assembly is suitable for circulating a heated heating medium in the curing bladder. A driving assembly of the vulcanizing equipment includes a rotating shaft sleeve that is arranged on the outer side of the center rod in a clearance-fit manner and is connected to the gas circulation assembly.

The present invention relates to deep-water drilling in petroleum engineering and, in particular, to a subsea wellhead pressure indicating and automatic adjusting device for deep-water dual-gradient drilling, comprising a subsea drilling fluid manifold system and a subsea wellhead pressure indicating and automatic adjusting system, wherein the subsea drilling fluid manifold system provides a flow channel for the drilling fluid returning through the wellbore so that the drilling fluid can smoothly return to a drilling platform, and provides a basis for the subsea wellhead pressure indicating and automatic adjusting system; and wherein the subsea wellhead pressure indicating and automatic adjusting system can display and adjust the subsea wellhead pressure in real time, in order to keep the subsea wellhead pressure to be constantly equal to the hydrostatic pressure of the seawater at the seabed. The present invention makes it possible to keep the subsea wellhead pressure to be constantly equal to the hydrostatic pressure of the seawater at the seabed in an automatic and real-time way, ensuring successful implementation of the dual-gradient drilling.
