Located at the top of pressure-relief valve block 5, pressure measuring tie-in 3 is located at 6 points of the side of pressure-relief valve block 5, force feed mouth flange 4 and oil return opening flange
Not She Yu pressure-relief valve block 5 two ends；After power station termination of pumping, the pressure in pressure oil pipeline and accumulator can be dynamic by buffer-type
Power station automatic pressure relief device is laid down, so it is prevented that anticipating due to still suffering from pressure in pressure oil pipeline and accumulator
Outward；And pressure relief device has pooling feature, impact during high-pressure system release can be avoided.
Embodiment 2：
As depicted in figs. 1 and 2, on the basis of embodiment 1, described force feed mouth flange 4, pressure measuring tie-in 3, electromagnetism overflow
Valve 2, choke valve 1 and oil return opening flange 6 are by the pipeline connection in sequential series inside pressure-relief valve block 5；Described force feed mouth flange 4
It is connected with the pressure oil pipeline of power station.There are force feed mouth flange 4, force feed mouth flange 4 and power station pressure oil pipe on pressure relief device
Road is connected and for pressure oil to cause pressure relief device, and pressure measuring tie-in 3 is installed to use in the position being connected with pressure oil on pressure relief device
Pressure measurement flexible pipe connects pressure gauge to observe pressure oil pipeline pressure, can simply and easily monitor the pressure condition inside pipeline.
Embodiment 3：
As depicted in figs. 1 and 2, on the basis of embodiment 1-2, described oil return opening flange 6 is by pipeline and fuel tank phase
Even pressure oil is unloaded to fuel tank during release, when power station normal work, the electromagnet of electromagnetic relief valve 2 is in dead electricity shape
