Abstract
The utility model relates to a liner mouth structure of a carbon fiber fully-wrapped composite gas cylinder with an aluminum liner of compressed hydrogen gas for a vehicle. The liner mouth structure is characterized in that a big linear mouth and a small liner mouth are respectively formed at both ends of an inner liner of the gas cylinder in a seamless neck-spinning manner; the diameter D1 of the big linear mouth is 85 mm, and the diameter D2 of the small liner mouth is 50 mm; threads are respectively processed on the inner walls of the big liner mouth and the small liner mouth, the thread for the big liner mouth adopts a straight thread (M50 X 2), and the small liner mouth (6) adopts a straight thread (M25 X 2); sealing grooves with the depths of 2.5 mm to 3 mm are respectively processed at the open ends of the big liner mouth and the small liner mouth, and the diameters D3 and D4 of the sealing grooves are respectively 55 mm to 57 mm and 30 mm to 32 mm; and the inner side edges of the sealing grooves have a certain slope, and the included angle alpha between the inner side edges of the sealing grooves and the axial direction is 3 degrees to 5 degrees. Since the drift diameter of a cylinder mouth at the big end is sufficiently large, a temperature sensor, a pressure senor and other components can be arranged for the purpose of monitoring the temperature and pressure in the cylinder and ensuring the safety in use of the gas cylinder; and meanwhile, the end at which a sensor is not required to be arranged is as small as possible, thereby further improving the sealing reliability, and not only meeting the demands of arrangement for the temperature sensor and the pressure senor, but also achieving the purpose of sealing.
Description
Technical field
The utility model is that a kind of vehicular compressed hydrogen carbon fiber twines aluminium courage composite cylinder courage mouth structure entirely, belongs to the technical field of structures of product.
Background technique
Domestic present fuel cell electric vehicle also is in conceptual phase, and the hydrogen cylinder that is adopted is carbon fiber and twines aluminium courage composite cylinder entirely, and working pressure has reached 35MPa.Fuel battery city carriage is big because of air consumption, and single bottle of water capacity is usually more than 120L, and a car need be installed many gas cylinders.When carrying out the design of fuel battery city carriage,, consider usually hydrogen cylinder to be installed in the top of car from secure context according to the characteristics of hydrogen gas leakage.Be subjected to the restriction of installing space, hydrogen cylinder is the long cylinder structure.The aluminium courage of this structure gas cylinder adopts aluminum pipe to make usually, is generally both ends open, and an end is installed the bottleneck valve, and the other end is installed plug.
Gas cylinder two ends bottleneck structure is identical.
The automobile-used hydrogen cylinder that present stage adopts all is to develop on the basis of compressed natural gas used as vehicle fuel gas cylinder, be test with bottle, and working pressure is 20MPa, can not satisfy the requirement of fuel cell car continual mileage.Must improve the working pressure of gas cylinder for this reason, increase hydrogen storage content.Under the condition that does not increase the hydrogen storage cylinder volume, must adopt the method that improves the hydrogen storage cylinder working pressure to increase hydrogen storage content.Current external automobile-used hydrogen storage cylinder working pressure is generally 35MPa, the domestic development work that also begins the automobile-used hydrogen storage cylinder of working pressure 35MPa.
Because of stored medium---the particularity of hydrogen, along with the raising of working pressure, the sealing difficulty at automobile-used hydrogen storage cylinder and cylinder valve and plug sealing surface place greatly increases.And in gas replenishment process, the temperature rise of medium hydrogen will be higher than other gas in the bottle, the temperature and pressure of gas in the therefore necessary bottle of monitoring in real time.
Want to monitor the temperature of bottle interior gas, must introduce temperature, pressure transducer in bottle, the connecting thread of the M25x2 that adopts usually is less than normal because of the aperture at present, is difficult to realize, needs to increase the size of connecting thread.The difficulty of the bottleneck sealing that increase connecting thread size then further improves.
From realizing the sealing angle, the more little easy more realization sealing of bottleneck latus rectum.But from Security and simple operation angle, be different from the gas cylinder of other medium, need in automobile-used hydrogen cylinder, introduce temperature transducer and pressure transducer, so that in use monitor the temperature and pressure in the gas cylinder at any time.This just requires the bottleneck latus rectum must enough could arrange these sensors down greatly.
Summary of the invention
The problem that the utility model exists at above-mentioned prior art just and design and provide a kind of vehicular compressed hydrogen carbon fiber to twine aluminium courage composite cylinder courage mouth structure entirely, its purpose is the specific demand at automobile-used storage hydrogen bottle, utilize the characteristics of gas cylinder both ends open, creationary bottleneck design proposal and the big latus rectum bottleneck sealing configuration scheme that has proposed small one and large one two kinds of bottleneck size, both satisfied the requirement of arranging temperature, pressure transducer, and effectively reduced spillage risk again and realized sealing.
The purpose of this utility model realizes by following measure:
The vehicular compressed hydrogen carbon fiber of this kind twines aluminium courage composite cylinder courage mouth structure entirely, this gas cylinder wall is a stratiform structure, from inside to outside be followed successively by aluminium courage layer, coating, carbon fiber layer and glass fibre layer, wherein, the carbon fiber room is to adopt hoop winding and spiral to twine alternately to be entwined, the thickness of aluminium courage layer is 3～7mm, the thickness of anti-static coating is 0.3～0.6mm, it is characterized in that: the inner bag of this gas cylinder is realized bold mouth and little courage mouth respectively in seamless spinning closing-in mode at two ends, courageously the diameter D1 of mouth is 85mm, the diameter D2 of little courage mouth is 50mm, courageously be processed with screw thread on mouth and the little courage mouth inwall, courageously mouth (5) screw thread adopts the M50x2 straight thread, little courage mouth (6) screw thread adopts the M25x2 straight thread, is processed with the seal groove that the degree of depth is 2.5～3mm at the bold opening end of mouth and little courage mouth, and the diameter D3 and the D4 of seal groove are respectively 55～57mm, 30～32mm, the inner side edge of seal groove has constant slope, with the angle α of axial direction be 3～5 °.
Technical solutions of the utility model are at the both ends open gas cylinder, only need an end enough greatly to satisfy the needs of arranging temperature, pressure transducer, therefore do not need the placement sensor one end bottleneck latus rectum can be little, guarantee sealing reliably.Do not needing placement sensor one end, whorl of bottleneck adopts the M25x2 straight thread.At needs placement sensor one end, whorl of bottleneck adopts the M50x2 straight thread.
The seal style of two ends bottleneck all adopts the seal with O ring structure, and O shape loop material adopts fluorine rubber.
