Specific embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
Body implementation method is described in further detail to the utility model.
As shown in Figure 1-2, the passive overflow exhaust apparatus of nuclear power plant includes：Frame assembly；Blade assembly, it is movably
It is arranged in the frame structure, is configured for bearing fluid-load, separates both sides headroom；Jackshaft, it is arranged on institute
State on frame assembly；The passive overflow exhaust apparatus of nuclear power plant and connecting rod, its one end are rotatably arranged on the jackshaft,
The other end is connected with the blade assembly.Also include constant force spring, it is arranged on the jackshaft, be configured to using described
The pulling force of constant force spring, when the blade assembly stress load reaches the predetermined spring tension of starting differential pressure, the blade group
Part is gradually opened, and is finally reached traffic requirement, realizes relief function, when the blade assembly stress load is less than predetermined bullet
During spring pulling force, the blade assembly is progressively closed off, the final plant closure when both sides pressure difference reaches closing pressure difference.The blade assembly tool
There are multiple blades.Seal groove and sealing strip is configured on the frame assembly to meet the requirement of sealing leak.
1. the structure and function of equipment
The overflow exhaust apparatus of the present embodiment is main by frame assembly, blade assembly, constant force spring, jackshaft, connecting rod etc.
Composition.Frame assembly plays support and installs positioning action；Blade assembly is used to bear both sides fluid-load, separates both sides space；
Using the effect of constant force spring pulling force, when blade assembly stress load reaches the predetermined spring tension of starting differential pressure, blade is opened
Beginning gradually opens, and is finally reached traffic requirement, realizes relief function, when blade assembly stress load draws less than predetermined spring
During power, blade starts to progressively close off, the final plant closure when both sides pressure difference reaches closing pressure difference.On frame assembly configure seal groove with
Sealing strip meets the requirement of reverse sealing leak.
2. the operation of equipment with use
Overflow mechanism frame assembly is fixed on IRWST steel module walls by welding manner, and opening is mounted laterally.Both sides
Respectively IRWST and safe shell-space, blade assembly are fixed by the pulling force of constant force spring, are maintained at arrival starting differential pressure
Front vane component is closed, and the big I of pretightning force is set according to starting differential pressure size.When IRWST and containment it
Between pressure difference when reaching starting differential pressure, blade assembly is acted on by aqueous fluid or water vapour pressure, its work on blade
When firmly more than the power of the pulling force generation of pretension component, blade starts to be opened along centre, and eventually arrives at predetermined design discharge,
Reach draining or degassing function requirement.In opening process, when the active force on blade draws less than constant force spring predetermined when closing
During power, blade begins to shut off, and final plant closure.The sealing strip on frame assembly is pressed on by the effect of constant force spring pulling force,
By the deformation in sealing strip, realize when reverse water level is higher than predetermined water level, the overflow of anti-water-stop body and leakage function.
The overflow exhaust apparatus of the present embodiment is used in nuclear power plant's passive cooling system between IRWST and safe shell-space
Overflow drainage and exhaust.When two side hydraulic pressures or differential pressure of atmospheric pressure are more than predetermined starting differential pressure, overflow mechanism can be with passive
Unlatching, be finally reached design discharge, when both sides pressure difference is less than predetermined closing pressure difference, device starts to progressively close off, and most
Close eventually.When water level rises in refuelling pool, sealing function is realized in overflow mechanism requirement, prevents the refluence of water.
