Description

Technical Field

[0001] The utility model belongs to the technical field of shot blasting devices, in particular to valve seat surface shot blasting processing equipment. Background Art

[0002] The valve seat is a removable surface part in the valve, which is used to support the fully closed position of the valve core and form a sealing pair. Generally, the valve seat diameter is the maximum flow diameter of the valve, and the shot blasting machine is a casting equipment that uses a shot blasting device to spray high-speed projectiles to clean or strengthen the surface of the casting. In order to clean the rust, scale and other covering layers on the surface of the valve seat, a shot blasting machine is used to clean the surface of the valve seat. However, the position of the shot blasting machine in most shot blasting devices is fixed, so that the position and angle of the projectiles ejected by the shot blasting machine are the same, which makes it difficult for the shot blasting machine to evenly clean the covering layer on the surface of the valve seat, thereby reducing the effect of cleaning the surface of the valve seat.

[0003] For example, the existing Chinese publication number is: CN207953595U casting shot blasting machine, which: "comprising a shot blasting chamber provided with a shot blasting machine, a casting conveying mechanism for conveying castings into the shot blasting chamber, a dust removal mechanism for dust removal, a shot sand recovery mechanism for recovering used steel sand, and a lifting mechanism for lifting old steel sand, the casting conveying mechanism is arranged at the feeding side of the shot blasting chamber, and the shot sand recovery mechanism is arranged at the bottom of the shot blasting chamber."
