Flexible valve for preventing falling objects by positive pressure on the upper part of a screw electric submersible pump

ActiveCN224397227UReduce risk of wear and leakageReduce the possibility of jammingCheck valvesFluid removalForeign matterScrew pump
The upper part of the screw electric submersible pump can be positively pressed to prevent the flexible valve from falling out, and relates to the technical field of oil pumping pump tools, which comprises a valve cylinder fixed on the upper port of the screw pump, a detachable lining ring connected in the valve cylinder, a high-molecular flexible valve plate fixed on the lining ring, and a flow passage is arranged in the center of the high-molecular flexible valve plate, and the center of the high-molecular flexible valve plate is convex upward and the flow passage is closed in the shutdown state. The utility model solves the problems that in the traditional technology, the impurities and other foreign matters in the oil pipe fall back into the pump when the screw pump unit is in the shutdown state, causing the blockage of the pump, and when the existing screw pump needs to be positively pressed through the oil pipe, the existing valve group structure is limited, and the pressure test function cannot be realized.

Tail gas treatment equipment for fluorine gas production

The invention belongs to the technical field of fluorine gas production, and particularly relates to a tail gas treatment device for fluorine gas production, the tail gas treatment device comprises a base station and a working box installed on the base station, a liquid changing assembly and a moving plate are slidably installed in the working box, and the working box is divided into a liquid changing cavity, a treatment cavity and a liquid discharging cavity by the liquid changing assembly and the moving plate; the working box is connected with the gas collecting pipe and the liquid inlet pipe, and the liquid changing assembly comprises a lifting ring and a rotating ring rotationally installed in the lifting ring. High-concentration alkali liquor is injected into a groove of a lifting ring through a liquid inlet pipe, so that the lifting ring compresses a long spring, a treatment cavity is communicated with a liquid changing cavity, then the lifting ring presses difluoromethane gas in the treatment cavity, and difluoromethane is conveyed to the liquid changing cavity through a gap between an upper top plate and a lower push plate; the difluoro-oxide in the liquid changing cavity reacts with high-concentration calcium hydroxide, so that the difluoro-oxide is treated, and the difluoro-oxide is prevented from leaking when the difluoro-oxide and alkali liquor in the treatment cavity are discharged out of the working box together.
