Embodiment Construction

[0009] The pebble bed high temperature gas-cooled reactor fuel element distributor proposed by the present invention, as shown in Figure 1, includes two positioning pistons 1 and 10, two reversing pistons 2 and 9, a rotating module 4, a hand wheel 6 and a valve core 8 . The spool 8 is installed in the valve body 11, and one side of the spool 8 and the valve body 11 is respectively provided with a goal pipe 5 and 15. The ball outlet pipe 16 and the rotating module 4 are placed side by side on the other side of the valve body 11 , and the ball outlet pipe 17 is opened on the rotating module 4 . The two reversing pistons 2 and 9 are installed on the two ends of the spool 8 respectively, and are sleeved in the two positioning pistons 1 and 10 respectively. The hand wheel 6 is placed on the cover plate 3 on one side of the valve body 11 , and the hand wheel 6 and the rotating module 4 are engaged with each other through the gear 7 . The end caps 12 on both sides of the valve body...

Abstract

A fuel element distributor of ball - bed high temperature GCR is prepared by setting valve core in valve body with ball inlets at one side of both, setting ball outlet and rotary module vertically at another side of valve body, arranging change over piston on two ends of valve core and sheathing it in two fixing pistons, placing handle on cover plate engaging and coupling handle with rotary module by gear, setting air inlet and outlet on cover plate placed at two sides of valve body.

Description

technical field [0001] The invention relates to a fuel element distributor for a pebble bed high-temperature gas-cooled reactor, which is used for distributing and transporting spent fuel balls and graphite balls discharged from the core of a pebble-bed high-temperature gas-cooled reactor, and belongs to the technical field of reactor engineering. Background technique [0002] There are two kinds of balls in the pebble bed high temperature gas-cooled reactor core, namely fuel balls and graphite balls. After being unloaded from the core, the two kinds of balls need to be transported to their respective storage containers. So far, there is no special equipment that can effectively transport two kinds of different balls to the storage containers as needed. . Contents of the invention [0003] The purpose of this aspect is to propose a fuel element distributor for a pebble bed high temperature gas-cooled reactor, which can transport and store different spheres separately, or ...
