Problems solved by technology

However, after the power of the core is reduced to a certain condition, it can be passively opened naturally to ensure the connection between the core and the pool, and the relevant literature on the passive switchgear that automatically establishes natural circulation has not been reported, and it is still blank in the field of reactor technology.

Embodiment Construction

[0011] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0012] Such as figure 1 , figure 2 The structural diagram of the passive switch is shown. The device is mainly divided into a valve body 1 and a rotating part. The valve body 1 is connected to the core by welding. The rotating part includes a damping arm 3 and a weight. The damping arm 3 and the weight The hammers are movably connected with the valve body 1 through the support respectively. The damping arm 3 and the heavy hammer can rotate under the action of the rotating shaft of the support. The damping arm 3 and the heavy hammer are independent of each other; The sheets 6 are connected to the damping arms 3 respectively. The weight of damping sheet 6 can be adjusted, and the damping sheet 6 that the present invention adopts is designed into different thicknesses and is made into several, reaches the purpose of adjustment. By adjusting the...

Abstract

The invention discloses a passive switch for a pool type reactor core and a pool. The passive switch is mainly divided into a valve body (1) and a rotating part, wherein the rotating part comprises a damping arm (3) and a counter weight; the damping arm (3) and the counter weight are moveably connected with the valve body (1) through a bracket respectively and are independent from each other; and a valve clack (2) and a damping sheet (6) are connected on the damping arm (3) respectively. The invention provides the passive switch for the pool type reactor core and the pool, which can prolong the service life of a valve, can satisfy different conditions and is turned on or turned off by means of gravity thereof.

Description

technical field [0001] The invention relates to the technical field of reactor engineering, in particular to a passive switch device for pool reactor cores and water pools. Background technique [0002] It is the development trend of advanced research reactors to adopt the combination of forced circulation and natural circulation for the removal of residual heat after the pool reactor is shut down. This requires that at the end of the forced cycle to ensure that the core is connected to the pool water, it is necessary to install a device on the core structure that is closed during the forced cycle and can be opened during the natural cycle. [0003] At present, most of the research reactors at home and abroad are equipped with related devices of various types, but most of the devices installed are active devices, that is, when the core is forced to circulate, it is strictly guaranteed to be closed, and when natural circulation is allowed , through the action of the operator...
