Description
Technical field
The present invention relates to the physical construction of liquid gas separation structure for detector in nuclear reactor and guiding, the specifically water level detector guide frame of a kind of liquid gas separation structure and formation thereof.
Background technology
Because nuclear reactor measuring system needs to continue to monitor reactor pressure vessel water level key point under operating mode after accident or accident, water level detector is then needed to be introduced in reactor by suitable structure, and the function utilizing the heat-transfer capability between water and steam to there is this principle of significant difference to realize measuring water level.
The existing nuclear power reactor of pressurized water type dispersed placement, the guide frame that detector assembly cluster type entirety is drawn by most employing, this guide frame requires that detector assembly possesses certain crooking ability, namely possess certain bending radius and angle of turn, require that reactor structure upper cover chamber possesses certain axial height simultaneously.In addition, because water level detector end position is in core exit, and may with bubble from the cooling medium of core exit outflow, if directly flow to water level detector, do not carry out the separation of liquid gas, this will affect the accuracy that water level detector is measured, and forms impact to water level detector, thus affects the serviceable life of water level detector.
So limited for upper cover chamber axial height, cannot arrange the reactor structure of cluster type detector assembly, guiding, the protection of water level detector introducing all do not reach requirement, and the mixing of liquid gas makes cooling medium impact water level detector.
Summary of the invention
The object of the present invention is to provide the water level detector guide frame being applied to a kind of liquid gas separation structure and forming; solve the problem that current cluster type detector assembly can not be applicable to existing pressure vessel; design the guide frame made new advances, for introducing guiding, the protection of the single detector in heap and supporting.
Object of the present invention is achieved through the following technical solutions:
Liquid gas separation structure, comprise connector, connector is connected with shunting body, connector and shunting body are provided with blind hole, the bottom of shunting body is the blind end of blind hole, shunting body sidewall is provided with multiple inclined hole, and the two ends of described inclined hole lay respectively at inside surface and the outside surface of shunting body, and wherein the level height of inclined hole outside surface port is greater than the level height of inside surface port.Liquid gas separation structure of the present invention be for the water level detector guide frame in nuclear reactor bottom parts, in order to be connected with guide frame, connector must be had, connector matches be connected pipeline configuration, shunting body is connected with in the below of connector, during using state, connector is positioned at top and shunting body is positioned at below, the inside of connector is cavity structure, this cavity is communicated be connected pipe interior, this cavity of connector extends to form blind hole from top to bottom in shunting body, the i.e. base seal of shunting body, the container of upper opening is formed on sidewall and bottom, the sidewall of shunting body is provided with multiple inclined hole, when using state, connector is normally coaxially connected with shunting body, its axis is in vertical direction usually, now, inclined hole tilts from its axis of lateral of shunting body, that is: inclined hole all has opening at the inner and outer wall of shunting body, and the open horizontal position of outer wall is higher than the horizontal level of wall opening in it, so, in use, liquid gas separation structure forms flow-guiding structure with installation guidance set sidewall, inclined hole defines coolant flow passage in core exit to support column cylinder, turn avoid the impact that core exit cooling medium brings to water level detector, from the alveolate cooling medium of core exit elution band, cooling medium upwards can flow along shunting body side, successively through shunting body side tiltedly under to inclined hole, blind hole flow into support column body interior, thus immersed water level detector, bubble then cannot by under tiltedly to inclined hole enter in support column, thus the liquid gas realizing the cooling medium of core exit is separated.
The axis of described inclined hole and surface level form downward angle α, and 0 ° of < α.
Described inclined hole is interspersed equably, is convenient to uniform liquid and enters in shunting body, and meeting under Structural strength calls prerequisite, the perforate total area is the bigger the better.
Water level detector guide frame, comprise the pressure vessel be arranged on pressure vessels top cover and run through base, also comprise the support column being arranged on pressure vessel and running through the guidepost between base dative frame plate and be arranged between upper bearing plate and upper core plate, support column base is installed bottom support column, above-mentioned liquid gas separation structure is installed in support column base.Guide frame of the present invention is formed primarily of two parts: targeting part and supporting part, wherein guiding part comprises guidepost, the upper end of guidepost extend into pressure vessel and runs through base internal fixtion, and pressure vessel runs through base is fixed on pressure vessels top cover, the lower end of guidepost is fixed on screen work plate, the critical piece of supporting part is support column, the upper end of support column is fixed on upper bearing plate, its lower end is fixed on upper core plate, support column is positioned at immediately below guidepost, support column is arranged on the discharge orifice of upper core plate, the entirety be made up of guidepost and support column provides guiding for detector, protection and supporting, and can after pressure vessels top cover is uncapped, for detector provides interim depositing, and realize detector, guidepost and the integral hoisting being arranged on the equipment on screen work plate, decrease the repetitive operation of extracting and inserting detector simultaneously, reduce dosage suffered by operating personnel, thus avoid the wearing and tearing repeatedly plugged detector, save the running time, improve economy.
