Description

汽化器减压膜 技术领域  TECHNICAL FIELD
本发明涉及液化石油气燃料汽车使用的汽化器， 特别是汽化 器内减压膜片的结构。  The present invention relates to a carburetor used in a liquefied petroleum gas fuel automobile, in particular to a structure of a decompression diaphragm in the carburetor.
背景技术 Background technique
由于作为传统汽车燃料的汽油在燃烧做功后所排出的废气 中含有大量污染环境的 HC、 CO和 ΝΟχ等化合物， 以洁净的能 源替代汽油是汽车业发展的趋势， 而以液化石油气替代汽油作为 汽车燃料的技术发展得较为成熟、 完善。 这一技术涉及到的主要 装置是汽化器 -其作用是将液态的石油气转化为气态。 汽化器包 括有电磁阀、 弹簧、 密封盖、 一级減压膜片、 排气管、 进气管、 排污管、 二级膜片、 压盖和壳体等构件。 而一级膜片是汽化器的 核心构件， 它在气缸吸气产生负压以及本身和弹簧的弹性作用下 往复振动， 使液化石油气减压而汽化。 由于膜片在汽化器腔内通 常工作温度为 - 40°C ~ + 120 、 振动频率为 0.5Ηζ ~ 1Ηζ、 工作 压力为 O.lMPb - 0.8MPb, 工作环境较恶劣， 且气体具有一定的 腐蚀性， 所以膜片在实际使用中极易老化、 疲劳而断裂， 且气体 具有一定的腐蚀性， 所以膜片在实际使用中极易老化、 疲劳而断 裂， 从而大大影响了汽化器的使用寿命。 另一方面， 平面薄片状 的膜片其振幅有限， 汽化效果也不佳。  Since gasoline, which is a traditional automobile fuel, contains a large amount of compounds that pollute the environment, such as HC, CO, and NOx, in the exhaust gas emitted after combustion work, it is the trend of the automotive industry to replace gasoline with clean energy. The development of automotive fuel technology is relatively mature and complete. The main device involved in this technology is the carburetor-its role is to convert liquid petroleum gas into a gaseous state. The carburetor includes components such as solenoid valves, springs, sealing caps, primary decompression diaphragms, exhaust pipes, intake pipes, blowdown pipes, secondary diaphragms, glands and housings. The primary diaphragm is the core component of the carburetor. It reciprocates under the negative pressure of the cylinder suction and the elasticity of the spring and the spring, which decompresses and vaporizes the liquefied petroleum gas. As the diaphragm in the vaporizer chamber usually has a working temperature of-40 ° C ~ + 120, a vibration frequency of 0.5Ηζ ~ 1Ηζ, a working pressure of 0.1MPb-0.8MPb, the working environment is relatively harsh, and the gas is somewhat corrosive. Therefore, the diaphragm is easily aged, fatigued and broken in actual use, and the gas has a certain corrosiveness, so the diaphragm is easily aged, fatigued and broken in actual use, which greatly affects the service life of the carburetor. On the other hand, flat sheet-like diaphragms have limited amplitude and poor vaporization effects.

参见图 1， 本发明的膜片本体 1基本呈圆形。如图 2， 3所示， 膜片振动部位 2位于本体 1中轴线一側，且***形成一振动腔 23， 振动腔 23与周边 24为阶梯式皱褶结构过渡， 如图 3所示皱褶结 构 25共三级。***的振动腔 23—方面使膜片弹性振动范围变大， 增大了汽化的空间容积， 有利于汽化效率提高； 另一方面也便于 形成皱褶结构 25, 提高了膜片的抗疲劳强度。  Referring to Fig. 1, the diaphragm body 1 of the present invention is substantially circular. As shown in Figs. 2 and 3, the diaphragm vibration portion 2 is located on the side of the central axis of the main body 1, and bulges to form a vibration cavity 23. The vibration cavity 23 and the periphery 24 transition in a stepped fold structure, as shown in Fig. 3 Structure 25 has three levels. The raised vibration chamber 23- on the one hand makes the diaphragm's elastic vibration range larger, which increases the volume of the vaporized space, which is beneficial to the improvement of the vaporization efficiency; on the other hand, it also facilitates the formation of a wrinkle structure 25, which improves the fatigue resistance of the diaphragm.
另外振动腔 23与周边的皱褶结构 25也可以是波浪式皱褶结 构过渡， 或者可以是半波式皱褶结构过渡。 当然， 其它波式皱褶 结构过渡的效果均相同或相近， 这里不再赘述。  In addition, the vibration cavity 23 and the surrounding wrinkle structure 25 may be a transition of a wave-type wrinkle structure, or may be a transition of a half-wave type wrinkle structure. Of course, the transition effects of other wave-shaped fold structures are the same or similar, and will not be repeated here.
此外可以在上述实施例的基础上扩展皱褶结构 25，即皱褶结 构 25布置于整个振动腔 23上，换言之皱褶结构 25延伸至振动腔 23顶部。  In addition, the wrinkle structure 25 can be expanded on the basis of the above embodiment, that is, the wrinkle structure 25 is arranged on the entire vibration cavity 23, in other words, the wrinkle structure 25 extends to the top of the vibration cavity 23.
至于膜片的材质， 可根据其皱褶结构而选择不同的材料， 可 以由金属材料制成， 或者也可以由橡胶制成， 或者可以采用其他 的弹性材料。  As for the material of the diaphragm, different materials can be selected according to its wrinkle structure. It can be made of metal materials, or it can be made of rubber, or other elastic materials can be used.
图 4和图 5的实施例示出使用金属材料的膜片 1的结构。 由 于膜片本体 1为金属， 在安装于汽化腔内时， 膜片本体 1的四周 及紧固位置上也要用密封橡胶 3上、 下覆盖， 以利于安装。 实验 表明， 本实施例的金属膜片在 1Hz振频下， 平均可振动 100万次 以上不破裂， 装车路试使用寿命达五万公里。  The embodiments of Figs. 4 and 5 show the structure of the diaphragm 1 using a metallic material. Since the diaphragm body 1 is metal, when it is installed in the vaporization chamber, the periphery of the diaphragm body 1 and the fastening position must also be covered with sealing rubber 3 up and down to facilitate installation. Experiments show that the metal diaphragm of this embodiment can vibrate more than 1 million times without breaking at an oscillation frequency of 1 Hz, and the service life of the road test of the vehicle reaches 50,000 kilometers.
