Description

高压储氢瓶组合阀 技术领域  High pressure hydrogen storage bottle combination valve
本发明涉及一种高压 （ 35MPa或 70MPa以上） 储氢瓶组合阀， 也可以 作为储氢瓶组的主阀， 同时可在天然气汽车中的储气瓶上使用。  The invention relates to a high pressure (35 MPa or more) hydrogen storage bottle combination valve, and can also be used as a main valve of a hydrogen storage bottle group, and can be used on a gas cylinder in a natural gas automobile.
背景技术 Background technique
国家科技部"十一五 "863 计划明确提出： 为加速推进氢燃料电池汽车工 程化， 同时为进一步提高其续驶里程， 将储氢压力提到更高的压力 （如： 35MPa )要求， 国际上已提高到 70MPa 的要求。 工程研究和市场需求提出 了研制一种既能对高压储氢瓶进行充气， 又能从中直接得到满足低压供气要 求、 结构紧凑和集诸多功能阀件于一体的主阀， 以替代目前常用的分列式布 局的储供气系统， 并进一步提高其安全可靠性。  The National Science and Technology Ministry's "Eleventh Five-Year Plan" 863 Program clearly states: In order to accelerate the engineering of hydrogen fuel cell vehicles, and to further increase its driving range, the hydrogen storage pressure is referred to higher pressure (eg: 35MPa) requirements, international The requirement has been increased to 70 MPa. Engineering research and market demand have proposed to develop a main valve that can both inflate high-pressure hydrogen storage bottles and directly meet the requirements of low-pressure gas supply, compact structure and many functional valve components, instead of the commonly used ones. The gas supply system of the distributed layout is further improved and its safety and reliability are further improved.
作为氢燃料电池汽车或天然气汽车用的氢气或天然气， 国内外通常均釆 用以高压气体状态充储于相应的储气瓶中， 而一般的储气瓶上往往只装一个 气瓶阀， 而后通过用具有相应功能的分列的单个阀件、 元器件及管路和控制 器件对高压气体进行输送、 控制及监示， 直至减低至所需压力后向燃料电池 或天然气汽车的发动机气缸供气。  Hydrogen or natural gas used as a hydrogen fuel cell vehicle or a natural gas vehicle is usually stored in a corresponding gas cylinder in a high-pressure gas state at home and abroad, and a general gas cylinder usually has only one cylinder valve, and then The high pressure gas is delivered, controlled and monitored by a single valve member, component and piping and control device with corresponding functions, until the required pressure is applied to the engine cylinder of the fuel cell or natural gas vehicle. .
针对氢燃料电池汽车的车载高压供氢系统研究与开发， 目前主要是加拿 大 Dynetek公司和美国 Quantum公司。 为适应氢燃料电池汽车的要求， 他 们都研制了 35MPa高压供氢系统。 两家釆取的技术路线有所区别： Dynetek 公司提供的储氢系统和输氢系统是相连接的， 也就是大多功能部件都要承受 35MPa 的压力， 总体布置是分散式的； Quantum公司提供的储氢系统和输 氢系统是分开的， 并在输氢时， 从车气瓶组附近就开始降压， 这样减压后的 功能件承受的压力较小， 系统相对操作安全， 在最新开发的世界上首台 35MPa和 70MPa氢气瓶系统中， 提出并设计出了气瓶组合阀， 气瓶组合阀 包括气瓶内置并加有电磁阀的减压调节阀、 PRD、 高压压力传感器、 温度传 感器及气体进出口， 且减压调节阀内置于氢瓶之内。 这种设计的优点是高压 氢气经气瓶组合阀的减压后， 低压输出， 提高了系统安全可靠性， 且由于减 压调节阀内置于氢瓶之内，可以减轻组合阀置于气瓶外部的重量和轮廓尺寸， 减小了气瓶瓶口的外部载荷，对车型对气瓶有轮廓尺寸要求的有极大的方便。 不足之处是由于减压调节阀内置于氢瓶之内， 造成了维修极大不方便， 且会 影响气瓶内部氢气有效存贮空间。 Research and development of on-board high-voltage hydrogen supply system for hydrogen fuel cell vehicles, currently mainly Dynetek of Canada and Quantum of the United States. In order to meet the requirements of hydrogen fuel cell vehicles, they have developed a 35MPa high-pressure hydrogen supply system. The two technical routes are different: Dynetek's hydrogen storage system and hydrogen delivery system are connected, that is, the large multi-functional parts are subject to 35MPa pressure, and the overall arrangement is decentralized; Quantum provides The hydrogen storage system and the hydrogen transfer system are separated, and when hydrogen is delivered, the pressure is reduced from the vicinity of the vehicle cylinder group, so that the pressure-reduced functional parts are subjected to less pressure, and the system is relatively safe to operate, and is newly developed. In the world's first 35MPa and 70MPa hydrogen cylinder systems, a cylinder combination valve was proposed and designed. The cylinder combination valve includes a pressure reducing valve built into the cylinder and equipped with a solenoid valve, PRD, high pressure sensor, and temperature transmission. The sensor and gas inlet and outlet, and the pressure reducing regulator are built into the hydrogen bottle. The advantage of this design is that the high pressure hydrogen is depressurized by the cylinder combination valve, the low pressure output improves the safety and reliability of the system, and since the pressure reducing regulating valve is built in the hydrogen bottle, the combined valve can be relieved to be placed outside the cylinder. The weight and contour size reduce the external load of the cylinder mouth, which is very convenient for the model to have the contour size requirements of the cylinder. The disadvantage is that the decompression regulating valve is built into the hydrogen bottle, which causes great inconvenience in maintenance and affects the effective storage space of hydrogen inside the cylinder.

The hydrogen storage bottle inflating and supplying air passages are connected to the combined valve body at one end, and the other end is used as an inflating inlet air passage filled with hydrogen gas, and an inflation sheet is sequentially connected in the hydrogen storage bottle inflating and the inflating inlet air passage of the air supply air passage. Directional valve and manual shut-off valve; two air passages are also drawn on the hydrogen storage bottle inflation and air supply air passages, and one air passage is used as the air supply air passage, which is taken from between the manual shut-off valve and the charge check valve, passes through the solenoid valve and The pressure regulating valve is used to supply air to the fuel cell; the other air passage is used as a pressure release air passage, which is taken out from the manual shut-off valve and the hydrogen storage bottle in the body of the combined valve body and the end of the air supply air passage, and is subjected to safety pressure. The release device and the gas release the airway and are released to the atmosphere. On the gas supply pipe outside the hydrogen cylinder combination valve, the pressure relief device should be added to ensure the normal operation of the pressure relief valve, which can increase the safety and reliability of the hydrogen cylinder combination valve and reduce its complexity. The high pressure hydrogen storage bottle combination valve is mounted on the high pressure hydrogen storage bottle through the bottle thread of the high pressure hydrogen storage bottle.
本发明的原理： 高压储氢瓶组合阀通过高压储氢瓶的瓶口螺纹安装在高 压储氢瓶上。 当向储氢瓶充气时， 气体只能经过充气入口气道、 充气单向阀 和手动截止阀， 通过储氢瓶充气和供气气道向储氢瓶内充气， 电磁阀激磁线 圈断电， 电磁阀处于关断状态， 安全压力释放装置在储氢瓶内的气体没有过 压 （如超压设定为额定压力的 105% ) 时处于关断状态； 当储氢瓶内的高压 气体向外供气时， 只能通过充气和供气气道、 手动截止阀进入供气气道， 经 过开启的电磁阀和减压调节阀向外供气， 如向燃料电池供气； 当经过减压调 节阀的气体压力高于设定范围时， 可以通过氢气瓶组合阀外的的供气管道上 的压力鋒放装置， 进行压力释放， 以保证减压调节阀正常工作。 当组合阀作 为储氢瓶组的主阀使用时， 则其它储氢瓶的高压气体经过预留的充气气道， 直接进入减压调节阀， 并通过供气气道供气。 压力释放气道是当储氢瓶内的 压力超过设定压力要求时所使用的安全压力释放气道。 The principle of the invention: The high pressure hydrogen storage bottle combination valve is installed on the high pressure hydrogen storage bottle through the bottle mouth of the high pressure hydrogen storage bottle. When inflating the hydrogen storage bottle, the gas can only be inflated into the hydrogen storage bottle through the inflation inlet air passage, the inflation check valve and the manual shut-off valve, and the solenoid valve excitation line is inflated through the hydrogen storage bottle inflation and the supply air passage. When the power is off, the solenoid valve is in the off state, and the safety pressure release device is in the off state when the gas in the hydrogen storage bottle is not overpressured (for example, when the overpressure is set to 105% of the rated pressure); When the high-pressure gas is supplied to the outside, it can only enter the air supply passage through the inflation and supply air passages and the manual shut-off valve. The solenoid valve and the pressure reducing regulator valve are supplied to the outside, such as supplying gas to the fuel battery; When the gas pressure of the pressure reducing regulating valve is higher than the set range, the pressure release device on the gas supply pipe outside the hydrogen cylinder combination valve can be released to ensure the normal operation of the pressure reducing regulating valve. When the combined valve is used as the main valve of the hydrogen storage bottle set, the high pressure gas of the other hydrogen storage bottle passes through the reserved inflation air passage, directly enters the pressure reducing regulating valve, and is supplied through the air supply air passage. The pressure release air passage is a safety pressure release air passage used when the pressure in the hydrogen storage bottle exceeds the set pressure requirement.
