Description

密封圈来回移动控制侧向气咀的气体采样袋阀门
技术领域
本实用新型涉及聚丙烯材料做成的气体采样袋阀门，尤其是在阀门顶盖顺逆时针旋转带动顶盖控制开关上的密封圈在阀门主体侧向气咀孔来回移动实现阀门开与关。
背景技术
目前，公知的聚丙烯材料做成有侧向气咀的气体采样袋阀门构造是由带侧向气咀阀门主体、顶盖控制开关、橡胶垫圈、紧固件串联而成。阀门与气体采样袋膜连接处从外到内依次是带侧向气咀阀门主体，橡胶垫圈、气体采样袋膜和紧固件的底部圆盘，通过顺时针旋转紧固件把阀门固定在气体采样袋上。顶盖控制开关内的硅胶垫来控制紧固件出气口，实现阀门开与关。当顶盖控制开关逆时针方向旋转使得顶盖控制开关内置的硅胶垫离开紧固件出口气，阀门就处于打开状态，此时就可以通过阀门主体侧向气咀向气体采样袋充气或气体从采样袋内放出；当顶盖控制开关顺时针方向旋转使得顶盖控制开关内置的硅胶垫压紧紧固件出口气，阀门就处于关闭状态，此时气体采样袋里面的气体就密封存储在里面。由于每个人的用力不一样，可能存在顺时针方向旋转顶盖控制开关，硅胶垫没有充分压紧紧固件的出气口导致气体采样袋内气体会泄漏。顶盖控制开关的外螺纹下端有一个密封圈，通常这个密封圈就靠着外螺纹下面，当顶盖控制开关逆时针方向旋开，有可能密封圈上移到阀门主体内螺纹内，此时给气体采样袋抽真空，顶盖控制开关的外螺纹与阀门主体内螺纹间隙会漏气。
发明内容
为了克服现有的带侧向气咀的气体采样袋阀门不方便操作而漏气的不足，本实用新型提供一种密封圈来回移动控制侧向气咀的气体采样袋阀门，该气体采样袋阀门顶盖顺逆时针旋转带动顶盖控制开关上的密封圈在阀门主体侧向气咀孔来回移动实现阀门开与关。
本实用新型解决其技术问题所采用的技术方案是：顶盖控制开关形状是总长度21.50mm，一端是直径为18.00mm厚度为2.50mm称为旋钮，紧挨着是M12的外螺纹，长度为6.50mm，紧挨着是直径8.50mm，长度为6.50mm圆柱面，紧挨着是凹槽，直径6.50mm长度1.80mm，紧挨着是直径8.50mm长度1.20mm的圆柱面，紧挨着是凹槽，直径是6.50mm，长度1.80mm，紧挨着是直径8.50mm长度1.20mm的圆柱面，顶盖控制开关两个凹槽套外径10.00mm内径6.00mm的密封圈，一般密封圈的内径比凹槽的圆柱直径小0.20mm到0.60mm之间。顶盖控制开关的旋钮以外的部分长度为19.00mm这段柱体中心是个直径4.90mm深19.00mm的孔。阀门主体构造是总长度是28.50mm，阀门主体一端有一个M12的内螺纹，长度6.50mm，紧挨着是内直径9.85mm，长度是12.50mm的光滑内柱面，紧挨着是内径为M8的内螺纹，长度为9.00mm，M8对应的外径14.00mm，其他部分对应的外径是15.00mm，在离M12这一端14.00mm的位置的侧面上有一个内直径2.00mm的侧向气咀孔，这个气咀与柱体垂直的方向，气咀长度30.00mm，外径6.20mm。紧固件构造是总长度25.00mm，中心有个2.00mm的通孔，一端是外直径4.00mm，长度14.50mm的圆柱体；紧挨着是M8的外螺纹，长度为9.00mm，紧挨着是外直径15.00mm，厚度为1.50mm的圆盘。顶盖控制开关的靠近旋钮的那个密封圈防止顶盖控制开关与阀门主体螺纹间隙漏气；当顶盖控制开关顺逆时针旋转时，另一个密封圈在阀门主体侧向孔来回移动来实现阀门开与关。一般情况下顶盖控制开关靠近旋钮的那个密封圈与顶盖控制开关M12外螺纹之间的圆柱面长度要大于等于顶盖控制开关的M12外螺纹长度，并且这个M12的外螺纹长度与阀门主体的M12内螺纹长度一致，这样子确保顶盖控制开关M12外螺纹与阀门主体M12内螺纹内外牙对上准备旋入的时候，这个密封圈已经开始起到防止M12螺纹间隙漏气。当顶盖控制开关顺时针旋到底时，顶盖控制开关上靠近旋钮的那个密封圈的位置最好在阀门主体侧向气咀孔的靠近旋钮的这侧；顶盖控制开关上远离旋钮的那一个密封圈的位置一定要在阀门主体侧向气咀孔的远离旋 钮的一侧，这个密封圈最大直径处的位置最好离孔的最近的这个边沿的距离范围为0.10mm到3.00mm。此时，从外界通过气咀向气体采样袋充气，气体被顶盖控制开关上远离旋钮的那一个密封圈堵住，气体进不了气体采样袋；同时气体采样袋里面的气体也无法出来，这样子阀门就处于关闭状态。顶盖控制开关逆时针方向旋转，顶盖控制开关远离旋钮的那一个密封圈朝旋钮方向移动，顶盖控制开关的两个密封圈都在阀门主体侧向孔中心的偏向顶盖控制开关旋钮的一侧，此时阀门开的状态，可以通过阀门气咀向气体采样袋内充气或从气体采样袋里面抽气。顶盖控制开关上远离旋钮的那一个密封圈起到阀门开与关的作用，而顶盖控制开关上靠近旋钮的那个密封圈防止顶盖控制开关与阀门主体螺纹间隙漏气。特别是当顶盖控制开关远离旋钮的那一个密封圈最大直径处位置在阀门主体侧向孔中心位置时，这个密封圈可能没有完全压住侧向孔，此时阀门处于开的状态，同时这个密封圈也起不了防止顶盖控制开关与阀门主体螺纹间隙漏气，因此，顶盖控制开关上需要两个密封圈分别承担各自的功能。如果顶盖控制开关旋钮中心打一个2.00mm的孔，然后从另一头装入直径5.00mm厚度2.50mm的硅胶垫，顶盖控制开关旋钮那个2.00mm的孔，就可以作为针筒取样的取样孔。
本实用新型的有益效果是，这种顶盖控制开关顺逆时针旋转带动密封圈来回移动控制侧向气咀实现阀门开与关的气体采样袋阀门，解决了顶盖控制开关操作不方便而且容易漏气的问题。
附图说明
下面结合附图和实施例对本实用新型进一步说明。

图2是密封圈来回移动控制侧向气咀的气体采样袋阀门的阀门主体结构示意图。
图3是密封圈来回移动控制侧向气咀的气体采样袋阀门的紧固件三视图。
图4是密封圈来回移动控制侧向气咀的气体采样袋阀门的顶盖控制开关、阀门主体及紧固件三个组装一起的结构示意图。
图5是密封圈来回移动控制侧向气咀的气体采样袋阀门的顶盖控制开关、阀门主体及紧固件三个组装一起的剖视图。
具体实施方式
在图1中，顶盖控制开关的旋钮中心有个2.00mm的小孔，里面放硅胶垫，用于针取样，两个凹槽是套密封圈的位置，从左到右第一个凹槽套的密封圈是用于防止顶盖控制开关与阀门主体M12内外螺纹间隙漏气，通常这个凹槽的左边的圆柱面的长度加凹槽的一半的长度大于顶盖控制开关M12外螺纹的长度。这个M12的外螺纹长度与图2阀门主体的M12内螺纹长度一致。这样子确保M12内外螺纹处于咬合状态下，密封圈可以保证螺纹间隙不会漏气。当顶盖控制开关顺时针旋转到底时，从左到右第二个凹槽的中心位置在图2阀门主体侧向孔远离顶盖控制开关旋钮的一侧，凹槽的中心位置最好离孔的最近的这个边沿的距离范围为0.10mm到3.00mm，此时阀门关闭。当顶盖控制开关逆时针旋转，从左到右第二个凹槽上套的密封圈最大直径处移到侧向孔的中心偏旋钮位置的时候，阀门打开，此时气体采样袋可以充气或放气。
在图2所示实施例中，阀门主体侧向气咀用于接乳胶管跟外界相连，侧向孔直径2.00mm，对应的外直径6.20mm，一般可以接内径为4.00mm外径6.00mm的乳胶管或内径5.00mm外径7.00mm的乳胶管。左边开口处是M12的内螺纹，用于装图1的顶盖控制开关；右边开口处是M8的内螺纹，用于装图3的紧固件。
在图3中，紧固件中间是2.00mm通孔，气体采样袋充放气都通过这个孔。紧固件左边外径4.00mm内径2.00mm的柱体伸入图1顶盖控制开关的4.90mm孔内顶住硅胶垫，以便取样用。紧固件右边的内六角孔，只是方便紧固装配用。紧固件右边的底盘表面的六个凹槽，方便气体采样袋抽真空用。紧固件的M8外螺纹一般跟图2的阀门主体的M8内螺纹长度一致。
在图4中，顶盖控制开关和紧固件都安装到阀门主体上的结构示意图。
在图5中，顶盖控制开关和紧固件都安装到阀门主体上的剖视图。
