The solution have the advantages that:
Of the invention is a kind of with the tank truck discharge pipe system for absorbing surge pressure, including flow container body and oil pump, liquid
The discharge port of tank body is connect by discharge pipe with oil pump, and discharge gate is provided on discharge pipe, further includes setting gradually
Filter, flowmeter and oiling reel, the input terminal of filter and the output end of oil pump connect, between flowmeter and oiling reel
Discharge pipe on be provided with accumulator；Accumulator includes shell, is set to the intracorporal scalable air bag of shell and is set to and can stretch
Oil pocket outside contracting air bag, scalable air bag is interior to be filled with inertia compressed gas.When work, in the scalable air bag of accumulator in advance
It is filled with the inertia compressed gas of certain pressure, when the pressure of discharge pipe is lower than the pressure of accumulator, stretching in accumulator
Contracting air bag can be expanded to maximum, and accumulator does not work；When the emergency for occurring needing to close discharge gate, discharge pipe
Surge pressure can be generated, when which is higher than the pressure of accumulator, the scalable air bag in accumulator is compressed at once, makes oil pocket
Interior volume enlargement to absorb pressure excessive in discharge pipe, and then makes the pressure in pipeline be limited in safe model
In enclosing.Therefore, compared with prior art, discharge pipe system of the invention will in time, can be unloaded quickly and safely in discharging
The surge pressure that pipe material generates sponges, and keeps the pressure oscillation in discharge pipe small, thus on effective protection discharge pipe
Equipment damage ensures operational safety.
