Longitudinal metal wave duct expansion joint and horizontal metal wave duct expansion joint are equipped in the pipeline that tank is connected with tank body；Pipe can be effectively eliminated
Thermal stress and deformation of the road on longitudinal direction and horizontal direction avoid support tower, tank body, fused salt heating storage tank and pump for liquid salts from bearing pipe
Thermal stress caused by road further increases the accuracy of test；
As a further improvement of the present invention, valve, the valve are equipped on the pipeline that fused salt heating storage tank is connected with tank body
Door also passes through emptying valve and connecting tube with the pipeline between tank body and is connected with remaining fused salt storage tank；Lead to a closing after testing to survey
Circuit main valve is tried, emptying valve is opened, fused salt remaining in pipeline is drained into remaining fused salt storage tank, avoids condensing in pipeline,
Guarantee going on smoothly for test next time；
In conclusion the present invention can effectively eliminate the thermal stress in system, the reference for installation that can avoid pump for liquid salts becomes
Shape, pump shaft generate the exception such as deflection, it is ensured that pump for liquid salts is safe and reliable in performance test, improves the accurate of test
Property.
