Safety valve online check instrument by mechanical fixtures, hydraulic power unit and data processing unit has three parts, small volume and light weight, modular components, computer equipment, simple operation, stable and reliable etc.,
1, the valve flap to open micro line detection, and online to jump the safety valve pressure setting, connected on the valve pressure setting, boiler safety valve safety valve, steam superheater safety valve, on-line calibration system without transformer, without disturbing conditions.
The 2 connecting parts design for the hydraulic cylinder and the displacement sensor frame mounted, with strong safety limit off mechanism, limit pull excess, rising amount of valve can be restricted below 1mm, the production conditions are not disturbed; the back seat is available after the limiting mechanism will be strong off the leak valve forcibly shut down, and does not affect the set pressure value. The utility model has the advantages of prolonging the service life of the equipment, creating a safe production environment, reducing the adjustment cost of the safety valve, and reducing the labor intensity of workers
Fixture: to ensure the safety of the test valve clamping positioning, hydraulic power unit to provide external force environment, the use of modular structure, very convenient disassembly.
Hydraulic power unit: to provide adjustable hydraulic output and flow, output 12MPa, lifting force of 50KN, to control the external lift and lifting speed.
