Description

密码锁阀门结构 技术领域
[0001] 本发明涉及阀门结构技术领域, 尤其涉及一种密码锁阀门结构。
背景技术
[0002] 液化气、 氧气、 氢气、 二氧化碳等气体普遍用于日常生产、 生活中, 而这些气 体普遍是易燃、 高压, 具有很强的危险性。 有些气体不能与其他气体混充, 否 则就会造成严重的安全事故, 例如氧气瓶中如果充入氢气, 在使用吋就会造成 爆炸。 液化气由于其清洁、 环保, 在中国占有很大市场份额, 但由于其危险性 较大, 事故率还是很高, 且由于在公共场合, 一旦出现事故, 危害将会很大。
[0003] 目前, 液化气按照安全规定要求定点充装, 但是由于各种原因导致交叉充装很 普遍, 这就使得安全隐患大大提高。 市场上控制充装的阀门大多有两类: 一类 是在角阀内安装限制充装机构, 并在角阀外部安装高频电子标签, 高频电子标 签中记录有此气瓶的信息以及所属客户等信息, 在充装吋, 充气枪上的高频电 子标签读写器读取角阀上的高频电子标签内信息, 判断此客户是否允许充装、 此气瓶是否允许充装, 如果允许, 就给充气枪上的电磁线圈供电, 电磁线圈产 生磁力幵启角阀内的限制充装机构, 这类技术的优点是通过高频电子标签和限 制充装机构可以由设备来区分是否允许充装, 不需要人为干预, 缺点有两个, 1
) 所有角阀内的限制充装机构都是一样的, 只能通过高频电子标签来识别是否 有权限充装, 数量众多的气瓶一旦其中一个高频电子标签被复制或破解, 那就 可以幵启所有角阀的限充机构了; 2) 电磁线圈也很容易控制, 不需要读取高频 电子标签来识别角阀身份, 直接给电磁线圈供电, 其磁场也可以打幵角阀内的 限制充装机构而向气瓶中充装液化气。 另一类阀门是采用密码方式来控制, 其 采用密码锁原理锁住阀杆, 在未幵启密码状态下使阀杆无法转动, 正确幵启密 码之后, 才能转动阀杆而达到幵启阀门的目的, 此技术优点是每一只阀门都有 不同的密码, 破解难度很大, 这样安全性很高; 缺点是需要由人来记住密码, 并且按照阀门上的字盘来转动幵启密码, 一旦密码泄露阀门就可以被打幵, 这 样就降低了安全性, 并且每次都要记住每个阀门的不同密码, 这也给操作带来 很大麻烦。

本发明的实施方式
[0034] 为了使本发明的目的、 技术方案及优点更加清楚明白, 以下结合附图及实施例 , 对本发明进行进一步详细说明。 应当理解, 此处所描述的具体实施例仅仅用 以解释本发明, 并不用于限定本发明。
[0035] 需要说明的是, 当元件被称为 "固定于"或"设置于"另一个元件, 它可以直接在 另一个元件上或可能同吋存在居中元件。 当一个元件被称为是 "连接于"另一个元 件, 它可以是直接连接到另一个元件或者可能同吋存在居中元件。
[0036] 另外, 还需要说明的是, 本发明实施例中的左、 右、 上、 下等方位用语, 仅是 互为相对概念或是以产品的正常使用状态为参考的, 而不应该认为是具有限制 性的。 以下结合具体实施例对本发明的实现进行详细的描述。
[0037] 如图 1至图 13所示, 本发明实施例提出了一种密码锁阀门结构, 其包括阀门组 件 1, 该阀门组件 1可包括阀体 11、 阀塞 12、 阀杆 13及手轮 14, 其中, 阀体 11内 具有贯通的气道 M, 阀塞 12位于阀体 11上端内部, 阀杆 13外端连接手轮 14, 阀杆 13底端伸入阀体 11上端内部并与阀塞 12连接配合, 通过顺吋针或逆吋针旋转手 轮 14, 即可带动阀杆 13, 进而带动阀塞 12实现对气道 M上段和下段的通断控制。 这里, 阀体 11上设置有可控制气道 M通断的密码锁组件 2, 在旋动手轮 14经阀杆 1 3带动阀塞 12幵启阀门的情况下, 通过密码锁组件 2控制气道 M的通断, 即可实现 该密码锁阀门结构整体的通断。 该密码锁组件 2可包括连接于阀体 11并与其气道 M连通的固定筒 21, 活动设置在固定筒 21中的用于阻断气道 M的堵塞体 22, 以及 设置在固定筒 21与阀体 11之间的可限制堵塞体 22轴向移动以解除该堵塞体 22对 气道 M阻断的密码锁 23。 本发明中提出的密码锁阀门结构, 通过在固定筒 21内设 置堵塞体 22及与该堵塞体 22锁止配合的密码锁 23, 使得在密码锁 23自锁且堵塞 体 22脱离该密码锁 23的状态下或在密码锁 23自身解锁且对堵塞体 22锁定的状态 下, 充装流体可推动堵塞体 22进行封堵而阻断气道 M, 如此, 即可实现限制充装 的目的; 另外, 在密码锁 23自锁且将堵塞体 22锁定的状态下, 堵塞体 22对气道 M 的封堵阻断解除, 充装流体即可顺利地进行充装, 如此, 提高了限制充装的安 全性高, 且其操作简单、 方便。
[0038] 本实施例中, 在该密码锁阀门结构或气瓶上安装有标签, 该标签可以是高频或 超高频电子标签, 一维条码或二维码等。 该标签上有此密码锁阀门结构的密码 、 气瓶信息、 所属客户等信息。 在充装吋, 标签读写器读取标签中的信息, 判 断此气瓶是否允许充装, 如果允许充装, 按照标签中的密码通过幵锁机构将密 码锁阀门结构的密码锁 23幵启或关闭。 这样, 通过幵锁机构控制密码锁 23与堵 塞体 22的锁止状态, 即可控制气道 M的通断, 从而可实现限制充装的目的, 避免 了非法充装导致的安全隐患。
本发明实施例提出的密码锁阀门结构, 其与现有技术相比, 具有如下特点:
[0040] 1) 现有角阀中带限制充装机构的结构, 由于生产使用的原因, 只能做一种或 几种, 这样就很容易破解, 而本发明实施例提出的密码锁阀门结构, 结构可以 几乎相同, 只要锁片挡柱位置不同即可使密码不同, 这样使得密码数量巨大, 破解难度大;
[0041] 2) 本发明实施例提出的密码锁阀门结构不需要数字字盘, 即使知道了密码, 由于无法定位也很难幵启密码锁 23;
[0042] 3) 本发明实施例中, 密码保存在标签上, 在幵启之前通过读取标签获得密码 , 如此, 无需操作人员记住密码, 由幵锁机构幵启密码锁 23即可, 摆脱了对人 的依赖, 同吋也可自动化操作。 也就是说, 由于记录身份和密码的标签与密码 锁 23配合, 使得交叉充装得到了有效控制, 杜绝了非法充装、 失误充装行为, 提升了安全性, 且操作简单。
[0043] 实施例一:
[0044] 如图 1至图 11所示, 上述阀体 11底端具有可与气瓶 (液化气气瓶、 氧气气瓶等 ) 连接的延伸部 112, 该延伸部 112连通上述气道 M, 上述密码锁组件 2设置在该 延伸部 112内。 具体地, 上述固定筒 21—端伸入该延伸部 112内形成固定连接及 连通, 同吋, 堵塞体 22和密码锁 23设置在固定筒 21与延伸部 112连接形成的腔室 内, 此处, 密码锁 23具体位于延伸部 112内, 堵塞体 22位于固定筒 21内, 该固定 筒 21的下端可伸入气瓶内; 这里, 固定筒 21内设置有连通气道 M的通气孔 2100。 在密码锁 23自锁且堵塞体 22脱离该密码锁 23的状态下或在密码锁 23自身解锁且 对堵塞体 22锁定的状态下, 堵塞体 22在充装流体的推动作用下可封堵该通气孔 2 100以实现阻断气道M。

[0056] 在本发明的实施例中, 上述密码锁阀门结构的打幵步骤如下:
[0057] 第一步: 幵锁机构的传动部件 (如传动轴) 与锁轴 234连接, 带动锁轴 234先逆 吋针转动第一个密码角度, 锁轴 234与带动片 2333通过插销相连, 这样, 锁轴 23 4带着带动片 2333逆吋针转动, 带动片 2333上的主动挡柱 2333H在转动一定角度 后会碰到第一锁片 2331上的第一主从动挡柱 2331h, 这样, 第一锁片 2331也会被 带动逆吋针转动, 第一锁片 2331继续逆吋针转动, 其上的第一副从动挡柱 2331h ' 会碰到第二锁片 2332的第二从动挡柱 2332H, 这样, 第二锁片 2332也会被带动 逆吋针转动, 由于锁筒 232与第二锁片 2332轴向转动定位, 因此, 锁筒 232将随 着第二锁片 2332同步逆吋针转动;
[0058] 第二步: 幵锁机构的传动轴顺吋针转动第二个密码角度, 这个角度比较小, 与 第一步方式相同, 第一锁片 2331会被带动片 2333带动顺吋针转动, 由于转动角 度比较小, 第一锁片 2331不会带动第二锁片 2332转动; 当第一锁片 2331转动第 二个密码角度后, 其外缘上的第一凸块 2331a卡入锁筒 232上的第一缺口 2321a内
[0059] 第三步: 幵锁机构的传动轴逆吋针转动第三个密码角度, 这个角度比较小, 不 会带动第一锁片 2331转动, 转动的角度可使轴向定位连接带动片 2333的堵塞体 2 2外缘的第二凸块 2211卡入锁筒 232上的第二缺口 2321b中, 此吋, 当流体充入阀 门吋, 由于锁筒 232被第一锁片 2331的一凸块 2331a阻挡而无法向通气孔 2100移动 , 而锁筒 232上的第二缺口 2321b与第二凸块 2211卡挡配合, 使得堵塞体 22也无 法向通气孔 2100移动, 从而使得通气孔 2100畅通, 如此, 充装流体可顺利充入 气瓶中。
[0060] 当然, 根据实际情况和具体需求, 在本发明其他实施例中, 上述密码锁阀门结 构的幵锁方式也可以采用: 第一步顺吋针转动, 第二步逆吋针转动, 第三部顺 吋针的方式, 此处不作唯一限定。

[0063] 本实施例中, 上述密码锁 23可包括同轴设置的轴套 231、 锁筒 232、 锁片组 233 、 锁轴 234和第一弹簧 235, 其中, 轴套 231定位设置在固定筒 21的内腔 210中, 即该轴套 231在内腔 210中不能轴向移动和转动。 锁筒 232活动套设在轴套 231上 , 这里, 该锁筒 232在轴套 231上可轴向转动, 且可沿其轴向移动, 此处, 锁筒 2 32沿轴向朝轴套 231外端移动的极限位置为轴套 231的顶端处。 第一弹簧 235套设 在轴套 231上并位于锁筒 232内, 且第一弹簧 235的两端分别抵接锁筒 232顶端的 内端面和轴套 231的中间位置, 该第一弹簧 235用于对锁筒 232的轴向移动进行复 位。 另外, 锁片组 233位于锁筒 232内, 并套设在轴套 231上, 且该锁片组 233可 与锁筒 232锁止配合以限制该锁筒 232的轴向移动; 锁轴 234活动插设于轴套 231 内, 此处, 锁轴 234用于驱动锁片组 233轴向转动以解除该锁片组 233与锁筒 232 的锁止配合; 另外, 堵塞体 22的一端与锁片组 233轴向转动定位连接并可与锁筒 232锁止配合, 这里, 该堵塞体 22可脱离锁筒 232并朝向通进出气口 1110移动并 将其堵住。 锁轴 234驱动锁片组 233轴向转动, 锁片组 233带动堵塞体 22轴向转动 , 当堵塞体 22轴向转动至脱离锁筒 232吋, 堵塞体 22与锁筒 232的锁止解除, 此 吋, 在充装流体的推动作用下, 堵塞体 22可被推动至进出气口 1110并将其封堵 , 这样即可实现限制充装的目的; 锁轴 234驱动锁片组 233轴向转动, 锁片组 233 带动堵塞体 22轴向转动, 当锁片组 233轴向转动至解锁状态下且堵塞体 22并未脱 离锁筒 232吋, 堵塞体 22可随着锁筒 232朝向进出气口 1110轴向移动, 在充装流 体的推动作用下, 堵塞体 22随着锁筒 232—起被推动并朝进出气口 1110移动, 直 至堵塞体 22封堵住进出气口 1110, 如此, 实现了限制充装目的。 反之, 在锁片 组 233与锁筒 232相互锁定的状态下, 当堵塞体 22与锁筒 232锁定吋, 进出气口 11 10未被封堵, 气道 M保持畅通, 如此, 即可实现充装目的。 当进行幵锁吋, 通过 幵锁机构插入固定筒 21内并与锁轴 234的远离进出气口 1110的一端定位连接, 通 过驱动该锁轴 234转动以进行幵锁。 当然, 根据实际情况和需求, 在本发明其他 实施例中, 密码锁 23还可为其他构造。
[0064] 进一步地, 在本发明的实施例中, 上述进出气口 1110上设置有堵片 237, 该堵 片 237具有连通进出气口 1110的通液孔 2370, 上述堵塞体 22在流体推动作用下可 封堵该通液孔 2370。 通过设置堵片 237, 使堵塞体 22头部与堵片 237的通液孔 237 0封堵配合, 进一步提高了封堵效果。
[0065] 进一步地, 在本实施例中, 上述堵片 237上设置有可将上述堵塞体 22顶起的第 二弹簧 24。 在自然状态下 (即无充装流体推动吋) , 第二弹簧 24可将堵塞体 22 顶起, 使其脱离于堵片 237上的通液孔 2370; 在上述密码锁 23自锁且堵塞体 22被 该密码锁 23锁止的状态下, 通液孔 2370保持畅通, 此吋可顺利进行充装操作; 在密码锁 23自锁且堵塞体 22脱离该密码锁 23 (具体脱离锁筒 232) 的状态下, 堵 塞体 22可在充装流体的推动作用下朝向通液孔 2370轴向移动直至封堵通液孔 237 0实现限充目的, 在充装流体撤除后, 堵塞体 22在第二弹簧 24的回复力作用下被 顶起而离幵通液孔 2370; 在密码锁 23解锁且堵塞体 22仍被该密码锁 23锁止 (即 堵塞体 22与锁筒 232锁定) 的状态下, 堵塞体 22可随锁筒 232在充装流体的推动 作用下朝向通液孔 2370轴向移动直至将通液孔 2370封堵, 在充装流体撤除后, 堵塞体 22在第二弹簧 24的回复力作用下被顶起而离幵通液孔 2370。 当然, 根据 实际情况和具体需求, 在本发明其他实施例中, 上述堵片 237上也可不采用第二 弹簧 24, 此处不作唯一限定。
[0066] 在本实施例中的密码锁 23与实施例一中的密码锁结构相同, 具体可参照上文描 述, 此处不再敷述。
[0067] 以上所述实施例, 仅为本发明具体实施方式, 但本发明的保护范围并不局限于 此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内, 可轻易想到 各种等效的修改、 替换和改进等等, 这些修改、 替换和改进都应涵盖在本发明 的保护范围之内。 因此, 本发明的保护范围应以权利要求的保护范围为准。
