Description

气体分配控制装置和具有此装置的气瓶
本发明涉及一种气体分配和控制装置，该装置可与一个盛有高压气体的容器相连，该装置包括一低压出口，和在容器与低压出口之间顺次地装有的一受高压作用的截流阀，一个可与截流阀联接的减压装置和一个流量调节装置。
本发明的目的是提供一种小型的人与机械控制组合型的气体控制和分配装置，一般永久地安装在气体容器或气瓶上，提供所需要的所有的功能和安全性能，既可分配气体又可填充容器。
为了这一目的，根据本发明的一个方面，低压出口、流量调节装置和减压装置装配在第一个活动的组件上，该组件置于控制驱动件中，控制驱动件紧密地连接到第二个组件上，该第二组件包括截流阀，并且一般直接安装在容器上。
根据本发明的其它特征：
第一组件包括第二个中压气体出口，它位于流量调节装置的上游；
减压装置安装在与第二组件的第一端相互滑动作用的第一座体内，并且有一个与截流阀选择性地相互作用的空心管部分；
压力调节装置包括一活塞装置，该装置支撑着一个阀，在第一座体内滑动，并与由第一座体形成的阀座相互作用；
流量调节装置和低压出口置于安装在第一座体上的第二座体内；
控制驱动件包括一个装有第一组件的管形件，其侧壁上有第一开口和第二开口，低压和中压出口管接头分别通过第一、第二开口伸出，第一、第二开口与第一组件置于同一侧有利。第二开口有一凸轮形外轮廓，与中压出口管接头相互作用以使第一组件随着管形件的转动而产生轴向移动。
本发明还涉及永久性地安装有这样一个组合装置的气瓶。
本发明的其它特征和优点将从下面相对附图所作的一个实施例的描述中体现出来，该实施例用于说明本发明而决不是对本发明的限制。
图1为根据本发明的一个安装于气瓶上的气体控制和分配装置的纵剖面图。
图2是带有在图1中用虚线表示的安全挡板的本装置的侧视图。
在所示的实施例中，本发明的装置一般包括一下座体，总体用标号1表示，其包括一具有螺纹的截锥形下端2以旋入气瓶4例如加压医用氧气瓶的瓶颈的螺纹孔3内。下座体1包括一个孔5，其贯穿下座体1的大部分长度并向下露出，截流阀6和它的弹簧置于孔5内，弹簧通常将截流阀6推至关闭位置，防止瓶4内的气体外流。第一横向阶梯形孔8和第二横向阶梯形孔10与孔5相通，第一横向阶梯形孔8用于安装指示瓶4内气压的气压表，第二横向阶梯形孔10用于安装一充气接头11，接头11内装有一单向阀12，接头11有一螺纹孔13，用于插接有外螺纹齿的快装接头(例如，入口孔直径小于螺纹孔13)，以便防止使用具有此特殊齿的快装接头以外的接头。下座体1的上部有孔14，外围凹槽15，并且在具有两个直径上对置的轴向切口551和552的槽处形成一裙状端。
孔14容纳一圆筒形中间座体17的裙状端，圆筒形中间座体17内装有一个由孔14的底部支承的弹簧18，圆筒形中间座体17有一中心空心管部分19，其限定了中心通道20并且向下延伸到座体1的小的中心孔21内，在座体1内在截流阀6的前方也相应地延伸有一个空心管部分。中心通道20向上通到一截锥形凸起中构成了一个阀座22，它位于中间座体17的扩宽的中心孔23的底部，在中间座体17的中心孔内，相对的横向孔24和25相通。中间座体17的上端以裙状形式扩宽形成上孔26，其内装有活塞27，它可在孔26内密封滑动。活塞27有一中心管28，它可在孔23内密封滑动，并在其端部带有阀垫29以与阀座22相互作用。活塞27的上表面经在管28内延伸的内孔30与孔23下部的压力相通，活塞27由支承在孔26底部的校准弹簧31推动离开阀座22。
孔26的上部由上座体32密封，上座体32通过螺帽33以密封的方式安装在中间座体17上。一个圆盘34安装于座体32下端的圆筒体内，圆盘34上有不同尺寸并按一定角度分布的一系列通孔35。通过一手动驱动装置，可使圆盘34相对于上座体32转动一定角度。该手动驱动装置有一中心杆36，该杆以密封方式轴向通过上座体32，中心杆36与圆盘34旋转接合，其上端与致动件固接，该致动件通常是一个与一个在上座体32之上的分度盘38成一整体的径向端腹板37，分度盘38的下表面有多个按一定角度分布的凹穴39，与安装在上座体32上向外弹性压力的球40相互作用。有利的是，上座体32的上端有一指示圆盘41，其与分度盘38平行并按一定角度分布有借助于分度盘38上的切口42可见的刻度。上座体32有一轴向通道43，与圆盘34的槽孔相通，并与横向孔44相通，用于安装低压出口接头45，该接头通常为一带凹槽的接头。
由中间座体17和上座体32组成的组件被安装在管形件46内，管形件46有一上端部47，其表面有刻痕，便于致动，圆盘42和驱动腹板37装于上端部47内。管形件46的下端有一系列的轴向长爪48，按一定角度分布，并且每一个有一带有截锥形内轮廓的内部的凸起，以与下座体1的截锥形斜坡状端部16相互作用，以便将管形件46安装在下座体1上，即将卡爪48永久地卡在外围凹槽15内，就能把管形件46及其内部组件牢固地固定在下座体1上，而另一方面，管形件46可绕下座体1及管形件46共同的轴相对下座体1转动。
管形件46的侧壁上有一上开口49，低压接头45可自由地穿过此开口，还有两个相对称的开口501和502，每一开口都有一横向凸轮外轮廓，并具有一个与一补偿阀装置(Surge valve device)52和中压接头51的中间部分的直径相配套的轴向延伸部分，中压接头和补偿阀装置分别安装在中间座体17中间的相对的两横向孔24和25内，并穿过管形驱动件46上的孔501和502和下座体1裙状上端的轴向切口551和552。中压接头51通常包括一单向阀53，当与使用管连接时其被推回。
以下是上述装置的操作：
起始于如图所示的关闭状态，驱动管形件46相对其它装置旋转，由于开口501和502凸轮形表面和相联的接头51和52之间的相互作用，由座体17和32构成的组件产生一克服弹簧18的向下移动，这一向下的移动导致中间座体17的中心管19向下推截流阀6，使截流阀6打开。由于弹簧31的校准力的作用，减压活塞27降低了气瓶4中的高压(如200×105Pa量级)，在孔23的下部降为中压(如医用3.5×105Pa量级)，在接头51的出口提供给用户高速中压气体，如：医用50-60升/分钟的量级。并列地通过旋转圆盘34选择孔35，用户可在低压出口接头45处获得低压气体，其压力一般略高于正常流速的大气压，流速的变化范围取决于流量调节器34、35的设定，一般医用流速为0至15升/分，这一流速适用于家庭治疗或急救用的装置的氧气罩或防护镜上。补偿阀52用于消除开口51和45出现压力过大的危险，在上述条件下，如果测定孔23压力超过5×105Pa，补偿阀就打开以进行调整。
从上述介绍可知，根据本发明的装置及所提供的气瓶4，可以向用户提供所需的预选的气体，这只要例如通过旋转驱动安装在气瓶4上的本装置端部因而容易通过起保护作用的盖或罩的顶部而接近的并列的元件47、37，另外，还可提供一种特别适合于医院和家庭的呼吸器的中压气体接口，所供给的气瓶里的气体连续地由压力表9监测。一旦气体用完，用户可将组件装置从安装台上卸下，将气瓶、气瓶上的气体控制和分配装置退回气体供应者，他用特殊工具可将气瓶通过充气嘴11充满，无需将本控制和分配气体装置从气瓶上卸下。
根据本发明的特性，为了特别适合于可运输的气瓶，所使用的接头45和51及压力表9安在本装置的同一侧，排成一行，对着在保护盖上形成的一侧向开口。
见附图2和附图1的虚线所示，该装置最好设有一由一挡板60构成的“标记”，挡板60经一杆61固定在管形件46上。杆61在接头42和51之间延伸，杆61的基部位于最靠近上部47的区域或开口49的顶部区域和开口501之间，挡板60具有一个纵向延伸部，以便在本装置处于关闭状态时，挡板60遮住接头42和51，防止管子与“关闭”的装置接通，这只要在关闭位置，标记挡板遮蔽了在气瓶的保护盖上形成的开口的主要部分即可。相反地，在装置的打开位置时，也准许驱动管形件46的挡板几乎全部藏在瓶盖内，接头42和41可自由进入，这样保证通入该处的管子与装有高压气体源的容器接通，这在医用上很重要。该装置的大部分部件是由金属制作的，弹簧由黄铜和钢制成，管形件46和典型地是挡板60可由塑料如聚酰胺(尼龙)制成。
虽然本发明是参考一具体实施例来说明的，但它的应用决不局限于此，并且可以包括对熟知该领域的技术人员明显的许多替换和变更。可以找到使用高压气体的广泛领域，特别是在焊接/切割等方面。
