Centralized type spherical pig receiving device

The invention discloses a centralized type spherical pig receiving device which comprises a pig receiving cylinder body. At least a route of spherical pig receiving pipeline is arranged just above the pig receiving cylinder body, the spherical pig receiving pipeline comprises inlet pipelines, pig receiving switching valves, barrier strip tee joints and flow switching valves are arranged at a position on the inlet pipeline near the pig receiving cylinder body for piping, and the spherical pig receiving pipeline is connected with the pig receiving cylinder body through a spherical pig inclined-in type inlet. The invention completes pig receiving operations of each route of the inlet pipeline through flow switching by arranging a plurality of routes of the inclined-in type spherical pig inlet pipelines and utilizing matched switch motion of the pig receiving switching valves with the flow switching valves on each inlet pipeline, can complete centralized spherical pig receiving operationsof the plurality of pipelines, and has the advantages of less necessary supporting valves, convenient installation, simple and convenient operation, simple flow, small occupying area, low investment,safety and reliability.
