This invention provides a feed adjustment bracket for a CVD furnace, comprising: a movable support; an adjustment bracket connected to the movable support via several adjustment components, the position of which can be adjusted vertically along the movable support via the adjustment components; and a mounting hole on the adjustment bracket, into which a feed pipe is installed via a fine-tuning component, the position of which can be adjusted radially along the mounting hole via the fine-tuning component. This invention uses the adjustment components, i.e., rotating a nut, to adjust the position of the adjustment bracket, aligning the feed pipe of the adjustment component with the feed hole of the CVD furnace. This achieves the effect of easily adjustable vertical position of the feed pipe, avoiding collisions or friction between the feed hole and the feed pipe due to misalignment, which could lead to damage.

The application belongs to the field of oil and gas exploitation, and provides a method for continuously extracting gas by using rheological metal temporary plugging and pressure lifting, which comprises the following steps: melting and solidifying the rheological metal plugging device in the continuous gas extraction pipe column until the pipe column is sealed; connecting the pipe with the fishing tool and connecting the fishing tool with the connecting part on the continuous gas extraction pipe column; driving the continuous pipe to ascend to drive the continuous gas extraction pipe column to move to a preset position; closing the blowout preventer to clamp the continuous pipe to keep the continuous pipe at a fixed height, and sealing the pipeline below the blowout preventer and connected with the wellhead; detaching the fishing tool above the blowout preventer from the connecting part; cutting the continuous gas extraction pipe column and the connecting part; connecting the end of the connector with the continuous gas extraction pipe column and the continuous pipe; opening the blowout preventer and sealing the pipeline above the blowout preventer; and driving the continuous pipe to ascend to drive the continuous gas extraction pipe column to be lifted out of the well. The application can safely and efficiently solve the problems of sealing the continuous pipe, lifting and unblocking the continuous pipe, and winding the pipe around the roller when the pipe is lifted out of the well.

The invention provides an austenitic stainless steel welding device, and relates to the technical field of stainless steel welding equipment, the austenitic stainless steel welding device comprises an equipment substrate, a movable bearing seat, a group of oppositely arranged pipe clamping mechanisms, a rotary driving mechanism, a butt joint pushing mechanism and a welding execution mechanism; the movable bearing seat is connected with the equipment substrate through a position adjusting mechanism; the group of pipe clamping mechanisms are symmetrically arranged at the top of the movable bearing seat; the rotary driving mechanism is in transmission connection with the pipe clamping mechanism; the butt joint pushing mechanism is arranged on the top of the movable bearing seat and abuts against the end of the pipe clamping mechanism. According to the pipe welding device, through cooperation of a double-buffering structure, a synchronous rotating driving mechanism and a precise guiding pushing mechanism, the stability problem of rotating butt joint is solved, and the pipe damage risk is avoided through buffering protection.

The utility model provides a compartment board processing clamp, including base, the top fixedly connected with two riser of base, be provided with support station between two riser, the both ends of support station and riser are up and down swing joint, the top of support station is provided with the clamping device close to both sides, the clamping device close to support station one side is fixedly set up, in the utility model, through setting up the support station for supporting the compartment board into the structure of up and down swing, makes the compartment board of vertical state when hanging one end will slide along the support station, then is blocked by the clamping device of bottom end, finally will and support station adhere, whole process only needs to control compartment board to drop, need not manual adjustment, and prior art compares has and the compartment board butt joint is more laborsaving, convenient, safe advantage.
