Abstract

The invention relates to the technical field of reactor auxiliary equipment, and discloses a flow blocker for a high temperature gas cooled reactor. The flow blocker comprises a casing and a rotor component. A cavity is formed in the casing, and a feed inlet and a discharge outlet both communicated with the cavity are arranged on the casing. The rotor component comprises a rotating shaft and a rotating disc. The rotating shaft is rotatably mounted in the cavity around the axis. The rotating disc is coaxially arranged on the rotating shaft. The outer peripheral surface of the rotating disc is in clearance fit with the curved surface of the cavity. The outer peripheral surface of the rotating disc is provided with a plurality of positioning grooves and at least one receiving cup for accommodating materials. The receiving cups are located between every two adjacent positioning grooves. An elastic block is embedded in each positioning groove. The outer surface of each elastic block is abutted against the curved surface of the cavity to stop gas circulation between the feed inlet and the discharge outlet. The flow blocker has the advantages that the elastic blocks are provided to achieve buffering through the elastic force, normal circulation, loading and unloading of spherical elements can be maintained, the stability in long-term operation is high, and high-temperature thermal expansion compensation and mechanical wear compensation can be realized.

Description

technical field [0001] The invention relates to the technical field of reactor supporting equipment, in particular to a flow choke for a high-temperature gas-cooled reactor. Background technique [0002] The pebble bed high-temperature gas-cooled reactor has the advantage of continuous refueling without stopping the stack, and its fully automatic fuel loading and unloading system is the key to ensure the continuous online operation of the pebble bed high-temperature gas-cooled reactor. The fuel loading and unloading system takes advantage of the favorable geometry of spherical fuel elements, and adopts two delivery methods for spherical fuel elements to realize the circulation, loading and unloading operations of spherical fuel elements. Pneumatic conveying using compressed gas. [0003] Chinese invention patent (publication number CN103474113B) discloses the composition and process flow of a pebble bed modular high-temperature gas-cooled reactor fuel loading and unloading ...
