Description

用于保持蒸气和气体以及排放压力和真空的热力阀
技术领域
本说明书涉及热力阀的开发，该热力阀用于保持蒸气和气体以及排放压力和真空，该热动力阀用于以下各项的通风(换气)：可燃液体(流体)的罐或容器，储存点处，工业中，或者任何其他用于储存或销售含有挥发性化合物的液体燃料的设施处。
背景技术
地下、空中或非空中的燃料罐或容器会受到由其填充过程和排空过程引起的温度和压力变化的影响。为了避免在填充过程和排空过程期间的爆炸危险，必须控制所述压力和温度变化。
为此目的使用的设备是用于保持蒸气和气体以排放压力和真空的热力阀，因为除了以积极的方式提供压力排放外，它还能够防止真空。这种阀安装在液体可燃物储罐中，其主要功能是产生压力排放和真空排放，通过保持蒸发损失来为储罐提供安全和保护。
通过安装用于排放压力和真空的热力阀，由于过载或过量的负压导致发生罐或容器破裂(捏合)的风险显著降低，因为在两个方向上(在每个方向上具有独立的压力)的空气流量都被释放。
另外，这种阀旨在保持挥发性蒸气和气体通过罐通风口排向大气，避免污染、损失、在通风口附近形成爆炸性混合物并且/或者防止罐通风口附近的任何人员发生职业疾病和偶然疾病。
现有技术的一个说明性示例为巴西实用新型MU 8301655-4，其描述了用于回收蒸气和气体的电磁阀，该电磁阀用于：使液体可燃物罐或容器通气，在该罐或容器中通过调节两个磁盘实现了阀的密封；有利于蒸气和气体在安装了该电磁阀的系统的内壁上冷凝；使所形成的液滴聚结，从而导致储存在罐中的可燃物质量返回。
作为现有技术文献所表现出的缺点，最公知的减压阀和压力阀使用了弹簧，如在美国专利文献US 4498493中可以看到的。
如巴西专利文献BR9801251-7的情况一样，其他阀也采用了电磁系统。
发明内容
旨在提供这样的阀：该阀免除了用于执行压力和真空控制的弹簧，同时不依赖于磁性来工作，本发明的热力阀被开发用于保持蒸气和气体以及排放压力和真空，通常是圆柱形或任何其他合适的形状。
概括地讲，本发明的阀包括上部隔膜环(3a)和下部隔膜环(3b)，这些隔膜环通过正压腔室(4)和负压腔室(5)内部的压力的热力学作用来自动调节。
具有向上定向的侧向开口的盖(2)拧在正压腔室(4)的主体上。
安装在盖(2)的上部区段上的破裂密封件(1)提供了额外的安全性。
在负压腔室(5)的内部下部区段处，底座(5.1)固定到燃料罐通风口，并且在底座(5.1)内，借助于O型环(7)固定防火织物(6)。
防火织物(4.1)定位在阀的正压腔室(4)和负压腔室(5)之间。
附图说明
本发明的表征是通过热力阀的示例性附图获得的，该热力阀用于保持蒸气和气体以及排放压力和真空，以使得能够通过最合适的技术完全复制产品，从而允许所要求保护的对象的全部功能。
这些附图仅仅是说明性的，并且可以接受各种变化，只要不背离最初要求保护的范围。在这种情况下，
图1是所提出的阀的透视图；
图2是该阀的横截面切割图；并且
图3是该阀的分解图。
具体实施方式
基于表示执行所设计产品的最佳形式或优选模式的所展示附图，本说明书的描述遵循详细且连续的编号，其中将由所采用的表示所暗示的方面被揭示以清楚地确定预期保护的对象。
本发明的阀结构紧凑，其主要工作原理是通过由螺纹固定在一起的正压腔室(4)和负压腔室(5)的内部的正压和负压的热力学作用自动调节两个隔膜环(3a、3b)。
具有向上的侧向开口(未体现)的盖(2)螺纹连接到腔室(4)的主体。
该阀借助于安装到盖(2)的上部区段并且被设计成防止过压的非金属破裂密封件(1)而具有额外的安全性。
该阀提供的经调节密封有利于蒸气和气体在内部燃料罐(未体现)壁上凝结、使所形成的液滴聚结，从而导致返回到储存在罐中的流体质量。
当燃料通过装载进入燃料罐时，即当罐接收燃料时，产生正压。
正压的排放是通过在燃料罐内产生空气和/或气体的增加的效果而发生的，该效果导致上部隔膜环(3a)在正压腔室(4)内部向上移动，从而降低在燃料罐内产生的正压。因此，负压腔室(5)内的下部隔膜环(3b)将防止正压的空气或气体从负压腔室(5)的下部开孔(未体现)中逸出。
当燃料通过排出而离开燃料罐时，即当燃料从燃料罐移动到加油站的供给源时，产生负压(真空)。
负压的排放是通过在燃料罐内部产生真空而发生的，下部隔膜环(3b)在负压腔室(5)内向上移动，旨在使空气能够进入燃料罐并防止塌缩。因此，定位在正压腔室(4)处的上部隔膜环(3a)将保持关闭状态，从而允许燃料罐内的压力均衡。
定位在负压腔室(5)的内部下部区段上的底座(5.1)设置有用于固定到燃料罐通风管(换气)的螺纹，该底座的内部具有通过O型环(7)附接的不锈钢防火织物(6)，旨在既防止燃烧进入系统内部，又保持固体颗粒。
为了保持固体颗粒，本发明的阀设置有另一个借助于不锈钢防火织物(4.1)的安全元件，该安全元件定位在正压腔室(4)和负压腔室(5)之间。
所述排放压力和真空的热力阀的特征在于：
·极端密封、确保产品损失最少和对环境的影响减小；以及
·调节压力非常接近开启压力，从而能够维持最佳的系统压力。
