Spherical vector spraying pipe structure

A spherical vector spraying pipe structure comprises a spherical cylinder, a spherical convergent flap, an adjustment sheet, a sealing sheet and mounting edge hinges, wherein the spherical cylinder is fixed, the spherical convergent flap is lapped with the spherical cylinder, sphere centers of the spherical convergent flap and the spherical cylinder are consistent, and a whole spraying pipe realizes vector deflection by rotating around the sphere center through the spherical convergent flap. The adjustment sheet and the sealing sheet of the spraying pipe are connected with the spherical convergent flap through the mounting edge hinges. The outlet area of the spraying pipe can be controlled by adjusting the lap size of the adjustment sheet and the sealing sheet, and the spraying pipe is constantly in the optimal working state. The spherical vector spraying pipe structure has the advantages that deflection efficiency and thrust efficiency can reach 100% as the throat area of the spraying pipe is unchanged after deflection, the structure is simple, fewer movement connectors are needed, and vector control of the spherical vector spraying pipe is easily realized.
