Oiltank structure component technology field.
Background technology
To replace fuel oil, the operating pressure of general CNG gas cylinders is most of taxi repacking compressed natural gas (CNG)
20MPa;Some vehicles producer has promoted the CNG or CNG vehicles mixed with fuel oil, such as Audi, general.Employ hydrogen
Fuel cell car is also current hot spot, and the operating pressure of hydrogen storage gas cylinder is generally 35MPa, 70MPa, and 70MPa
IV types bottle (high-pressure plastic liner clad vessel) is current research and development focus.In addition to automobile-used, gas cylinder is also obtained in other field
Partial liquefaction oil gas to sufficient application, such as Europe uses plastic inner lining clad vessel (operating pressure 2MPa).Largely
High-pressure bottle be used widely in daily life, traditional simple metal or metal inner lining clad vessel are bigger than normal there are weight
The problem of, it is not easy to transport;And storage pressure is higher, metal inner tube production technology is more complicated, and cost is higher, also exists by high pressure gas
The risk of body corrosion.In order to meet light-weighted requirement, high-pressure plastic liner clad vessel generates, should because of the characteristic of plastics
Class product has the superior functions such as corrosion-resistant, endurance, and main production firm is Toyota, Hexagon (Norway), Quantum (U.S.s
State) etc..Relative to simple metal or metal inner lining clad vessel, the guarantee of the leakproofness of high-pressure plastic liner clad vessel is more severe
It carves, main cause is that plastic inner lining is different from the material of metal termination, during use repeatedly, plastic inner lining and metal end
Head connection can loosen, and sealing performance declines.
In view of the hot spot and difficult point that connect into for research of present situation, metal termination and plastic inner lining.Fig. 1 show one
High-pressure plastic liner clad vessel, metal termination 1 are mounted on plastic inner lining 2, are twined later by fiber composite layer 3
Around being wrapped to form.Fig. 2 illustrates the sealing structure of end face:Metal termination 1 is contacted with the big face of plastic inner lining in technique
It is infeasible, even if feasible cost is also high;The structure does not consider metal termination 1 and the limit on 2 axis of plastic inner lining
Position;The structure does not consider the internal pressure changing pressurising of plastic inner lining during winding, and metal termination 1 and plastic inner lining can be caused to connect
The place of connecing generates gap and causes leakage;The structure does not consider limiting when bottleneck bears installation torque, and metal termination 1 is caused after installation
It is reduced with the bond strength of composite bed 3;The escape paths P of compressed gas is shorter in the structure, can increase compressed gas escape
Risk, especially micro-molecular gas hydrogen, helium.Therefore, there is an urgent need for a kind of new schemes to solve the technical problem.
