Draining and atomizing throttling device

The invention discloses a draining and atomizing throttling device. The device comprises a main body; an upper joint and a sand preventing seat which are fixedly connected are respectively arranged at two ends of the main body; the main body comprises a mandrel, slips, a centering body and an inclined teeth cap, wherein the mandrel comprises an upper mandrel and a lower mandrel; the slips are embedded and fixed through a slips seat; a centering plate and a centering plate spring clamped into the centering plate are fixedly arranged on the centering body a downward pressing manner; the inclined teeth cap is embedded and fixed through an inclined teeth cap seat; an aluminum anode and a filtering screen plate connected with the aluminum anode are arranged at one side of a sand preventing seat joint. According to the device, the liquid is atomized, thus the mixture density of natural gas and water can be reduced, and the cost can be effectively reduced; the structural design is simple; the failure rate due to parts fault can be reduced; the device is easy to launch and pick; the service life can be effectively prolonged; a rubber barrel is initially closely sealed, and the initial sealing force of the rubber barrel is controlled through upward lifting pull force, so that the sealing performance of the rubber barrel can be ensured; the assembly and spare parts are flexible in design, and convenient to reconstruct and debug; different user demands can be met.
