Blanking plug with circulating well washing channel

The utility model discloses a blanking plug with a circulating well washing channel, which comprises a blanking plug upper shell and a blanking plug lower shell, and an upper circulating hole is formed on the blanking plug upper shell; the blanking plug upper shell and the blanking plug lower shell are buckled to form a valve plate cavity, a valve plate is arranged in the valve plate cavity, and the valve plate is fixed to a boss at the bottom of the valve plate cavity through a valve plate action spring. And a bottom circulating hole is formed in the bottom of the blanking plug lower shell. When the electric submersible pump works normally, well fluid short circuit can be prevented, the requirement for a Y-shaped pipe column production fluid flow channel is met, when the electric submersible pump stops running and needs to conduct well washing and killing operation, a reverse well washing channel can be established, circulating well washing and killing are achieved, and the electric submersible pump is simpl
