Description
Technical field
The utility model relates to a kind of sealing mechanism, says more specifically, it relates to a kind of two wall high-pressure line sealing mechanism.
Background technology
High-pressure line is the integral part of high-pressure oil passage on engine, require that oil pipe needs to bear certain oil pressure, and have certain fatigue strength, ensure the seal request of pipeline, high-pressure line generally adopts twin wall emitter lateral, the higher oil pressure that twin wall emitter lateral can bear, oil pipe not easily leaks, fracture, but the sealing of the joint of double wall oil pipe two ends coupling end is thorough not, due to the impact of high-pressure oil, the joint of coupling end is easily leaked, Leakage Energy can leak into engine interior from coupling end, cause engine generation fault, affect the safety of engine operation efficiency and staff.
Practical novel content
Technical problem to be solved in the utility model is to provide a kind of two wall high-pressure line sealing mechanism, it has multi-sealed device, the joint Leakage of two wall high-pressure line coupling end can be solved, and can occur to trigger rapidly warning device when leaking by fuel oil in pipeline, remind staff to keep in repair in time, avoid accident to occur.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of two wall high-pressure line sealing mechanism, it comprises high-pressure line and is located at the joint of high-pressure line end, described high-pressure line comprises interior pipe and sleeve pipe, described sleeve pipe is wrapped in outside interior pipe, sealing mechanism also comprises trim ring, O RunddichtringO A, O RunddichtringO B and eccentric cover, described trim ring adopts with interior pipe and is threaded, and described trim ring embeds joint inside, O RunddichtringO A it is provided with between described joint and sleeve pipe, described joint has through hole A, described through hole A is positioned at outside cannula end extended line, described joint outer sheath has eccentric cover, it is provided with O RunddichtringO B between described joint and eccentric cover, described bias puts and is provided with the through hole B corresponding with through hole A.
Further, described through hole B diameter is greater than through hole A diameter.
Further, described O RunddichtringO B is located at through hole B both sides.
Further, described inner tube length is greater than the length of sleeve pipe.
During work, after interior pipe leaks, Leakage Energy will enter in sleeve pipe, now Leakage Energy will flow to joint along sleeve pipe, first once sealing is carried out by the trim ring between joint and interior pipe, then secondary seal is carried out by the O RunddichtringO A between sleeve pipe and joint, prevent oil leakage to engine interior, three sealings are carried out finally by the O RunddichtringO B between joint and eccentric cover, ensure that Leakage Energy can only be flowed into used oil pipe by through hole A, the through hole B that joint and eccentric cover are inner, warning device can be triggered simultaneously, then flow back in fuel tank.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model adopts multi-sealed mechanism, it is possible to effectively preventing fuel oil from leaking into engine interior in high-pressure line joint, safe reliability height, not easily has an accident; The sealing element used is all standardized component, and it is convenient to buy, and interchangeability is good, it is easy to maintain and replace; It is provided with through hole in sealing mechanism and connects used oil pipe, warning device can be triggered rapidly when leakage of oil, remind staff to keep in repair in time, avoid causing bigger loss.
