Description
Technical field
The present invention relates to a kind of explosion bulge test device, it is primarily directed to tubing explosion bulge test, especially a kind of tape verifier
The tubing explosion bulge test device of structure.
Background technology
The working environment of automobile product oil pipe is more complicated, in addition to oil medium, also can bear high pressure, hyperpyrexia and strong
Power, if oil pipe quality does not pass a test, occurs the danger of oil pipe blast, once oil pipe explodes, high pressure in use
Fuel oil may spray out, the high temperature that the equipment of high-speed cruising produces is also possible to light fuel oil, and the phenomenon of vehicle burning occurs,
Injure the safety of passenger.And oil pipe burst, also can reduce the handling of vehicle, the vehicle especially run at high speed,
Become uncontrollable, easily cause serious vehicle accident, jeopardize other vehicles and pedestrian, therefore automobile product oil pipe makes in input
With front, it is required for through oil pipe explosion bulge test.
Existing oil pipe bursting test machine, when test, has two kinds of situations and causes oil pipe unqualified, and one kind is oil
Pipe sole mass is not up to standard to cause oil pipe unqualified, and another kind is that bursting test machine has leakage and causes oil pipe unqualified.But
All thinking during the underproof result of oil pipe, occurs in the mechanism that existing oil pipe bursting test machine does not all verify to bursting test machine
It is that oil pipe sole mass is not up to standard to cause that such result of the test and the larger difference of physical presence can cause oil pipe qualification rate
Degradation.
Patent Office of the People's Republic of China discloses a cn102645376a document, a kind of entitled oil pipe on the 22nd in August in 2012
Explosion bulge test device, including the storage box for accommodating test fluid, is provided with the experimental tank of petroleum pipeline fixation kit, for even
Logical storage box and the pipe-line system of petroleum pipeline, pipe-line system includes the runner pipe being connected with storage box and petroleum pipeline, and
