Throttle manifold for preventing flow leakage

The invention discloses a choke manifold for preventing flow leakage, and relates to the technical field of choke manifolds. The choke manifold comprises a bottom plate, a box body, an oil inlet pipe and a cross plate, and the surface of the box body communicates with a guide pipe. According to the choke manifold for preventing flow leakage, the filter screen is arranged in the oil inlet pipe, then the fan blades arranged in the oil inlet pipe are driven to rotate through the impact force of flowing of petroleum, the scraping plate behind the fan blades scrapes impurities adsorbed on the filter screen, and the impurities are stored in the groove in the bottom of the interior of the oil inlet pipe; in addition, the movable rod with the fan blades is arranged on the cross plate, the cross plate is clamped between the two flange plates, the stability of connection between the flange plates can be improved, relative movement of the flange plates can be avoided, after the flange plates are loosened, the nut is dir
