本申请要求于2014年10月14日提交中国专利局、申请号为201410540086.7、发明名称为“一种液化气瓶阀门”的中国专利申请和2014年7月31日提交中国专利局、申请号为201410373631.8、发明名称为“一种液化气充气枪”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及燃气技术领域，更具体地说，涉及一种液化气瓶阀门以及与上述液化气瓶阀门配合的液化气充气枪。
背景技术
近年来，液化气以方便清洁的优点迅速进入千家万户，但是充装液化气的液化气瓶可能存在的安全隐患，会危急到人身及财产安全。
为确保用户生命财产安全，液化气瓶充装采用定点充装方式，因此为液化气瓶建立完善的管理档案，从而杜绝使用未检、报废的液化气瓶。但是，由于液化气经营企业及其供应站点对液化气瓶的管理较为混乱，气瓶档案没有在充装过程中得到利用，普遍存在液化气瓶非定点充装，甚至使用报废液化气瓶等现象，导致大量不合格液化气瓶仍在使用，存在很大的安全隐患。现有技术中阀门是一个纯粹的机械设备，只能完成物理的充放气功能。有扫描式液化气充气枪，其包括扫描仪、充气枪体，另外，在液化气瓶上贴有表明液化气瓶身份及信息状态的标签，实际使用时，先用扫描式液化气充气枪上的扫描仪扫描液化气瓶上的标签，如果标签表明该液化气瓶合格，则由工作人员打开阀门为液化气瓶充气，如果该液化气瓶不合格，则不为其充气。这种依靠人工控制液化气瓶阀门启闭的过程，不能从根本上杜绝不合格液化气瓶的再使用现象，同时也不能杜绝非定点充装液化气的现象。
因此，如何杜绝非定点充装液化气的现象，实现自动禁止未检钢瓶、报废钢瓶的充装，是目前本领域技术人员急需解决的问题。
发明内容
本申请提供一种液化气瓶阀门以及液化气充气枪，用于杜绝非定点充装液化气的现象。
为实现上述目的，现提出的方案如下：
一种液化气瓶阀门，包括：
阀体，阀体的侧壁上设置有充气口；
嵌入阀体侧壁上的驱动环滑座，且驱动环滑座与阀体固定连接；
具有固定连接的套环部和延伸部的驱动环，套环部套设在驱动环滑座上的且能够沿着其滑动，套环部外壁上具有凸起的抵接部，延伸部具有卡孔；
套设在套环部上的第一线簧，第一线簧的一端与抵接部相抵另一端与阀体的内壁相抵；
固定于阀体内部的具有通气孔的插套，通气孔与充气口连通；

套设在接杆上的第二线簧，第二线簧的一端与卡接部相抵另一端与插套的内壁相对固定。
优选地，上述液化气瓶阀门中，驱动环滑座的轴向垂直于阀体的轴向，且驱动环沿着驱动环滑座的轴向滑动，且通气孔的轴线和接杆的轴线均沿着竖直方向设置。
优选地，上述液化气瓶阀门中，卡孔的靠近抵接部的一侧具有让位孔，接杆的卡接部能够穿过让位孔。
一种液化气充气枪，包括充气枪本体和设置在充气枪本体上的手动卡装装置；手动卡装装置包括：
一端与充气枪本体铰接的拉杆；
一端与拉杆的中部铰接、另一端与充气枪本体的用于安装卡装头的往复杆铰接的连杆；
往复杆设置在充气枪本体的滑槽中；
还包括设置在充气枪本体上的控制系统，控制系统包括：
用于读取液化气瓶设置的智能标签的气瓶信息的读取模块；
与读取装置相连接的判断模块，设置有判断信号输出端，判断信号输出端配置为当气瓶信息为合法信息时输出合法充气信号；
与判断信号输出端相连接的控制模块，设置有控制信号输出端，控制信号输出端配置为根据合法充气信号输出充气控制信号；
与控制信号输出端相连接、用于根据充气控制信号输出控制磁场的感应装置；
控制磁场用于打开液化气瓶设置的智能角阀的限充装置。
优选的，控制系统的电源装置包括：
用于输出低压直流电的整流电路；
与整流电路相连接、用于根据低压直流电输出低压交变电流的逆变电路；
控制模块设置有用于接收低压交变电流的电能输入端，控制信号输出端输出的充气控制信号为低压交变电流。
优选的，还包括用于连接控制信号输出端与读取装置的过流/过压保护装置。
本申请提供的液化气瓶阀门包括阀体、驱动环滑座、驱动环、第一线簧、插套、接杆和第二线簧。其中，阀体的侧壁上设置有充气口。驱动环滑座嵌入阀体侧壁上，且驱动环滑座的轴线与阀体的轴线之间具有夹角，并且驱动环滑座与阀体固定连接，为了防止液化气泄漏驱动环滑座与阀体应该密封固定连接。驱动环具有相互固定连接的套环部和延伸部，套环部套设在驱动环滑座上，延伸部由套环部靠近阀体轴线的端部向靠近轴线的方向延伸形成，且套环部能够沿着其滑动即套环部沿着驱动环滑座滑动时驱动环整体滑动，套环部外壁上具有凸起的抵接部，延伸部具有卡孔。第一线簧套设在套环部上，且第一线簧的一端与套环部外壁上的抵接部相抵 另一端与阀体的内壁相抵，当套环部受到充气枪的控制磁场产生的安培力时会沿着驱动环滑座滑动后会拉伸或者压缩第一线簧，当充气枪的控制磁场产生的安培力消失时套环部会由于第一线簧的弹力复位，实现驱动环的自动复位。
插套固定在阀体内部，且插套具有通气孔，通气孔与充气口连通，且通气孔与该阀体的出气口连通，通气孔可以沿着阀体的轴向设置。接杆插设于插套的通气孔内，并且接杆能够沿着通气孔移动，即接杆沿着通气孔的轴向移动，接杆上固定有第一密封件和能够卡在卡孔上方的卡接部，卡接部卡设在卡孔上方时第一密封件与通气孔的孔壁密封接触，卡接部脱离卡孔上方时第一密封件与通气孔的孔壁之间具有间隙，其中卡接部脱离卡孔上方时，接杆会由于重力下降。第二线簧套设在接杆上，并且第二线簧的一端与卡接部相抵另一端与插套的内壁相对固定，如此当接杆由于重力下降时，其卡接部会压缩或者拉伸弹簧，如此可以通过第二线簧的作用将接杆复位。
液化气充气枪包括充气枪本体和手动卡装装置。该手动卡装装置包括拉杆和连杆，拉杆的一端铰接在充气枪本体上，连杆的一端与该拉杆的中部铰接在一起，另一端与安装有卡装头的往复杆连接。拉动该拉杆可以带动连杆，连杆拉动往复杆在充气枪本体的滑槽中滑动，并带动其上的卡装头将液化气瓶的智能角阀卡住，从而充气枪本体的充气嘴与阀门的进气嘴紧密连接。
还包括设置在充气枪本体上的控制系统，其包括读取模块、判断模块、控制模块和感应装置。读取模块设置在充气枪本体上，具体设置在充气枪本体的往复杆内，用于读取设置在液化气瓶上的智能标签内的气瓶信息，该读取模块利用接触式读卡器或者非接触式读卡器对智能标签中的气瓶信息进行读取。判断模块与该读取模块相连接，用于对读取模块读取到的气瓶信息进行判断，判断该气瓶信息是否为合法信息、是否为未经检验或已经报废的液化气瓶。如果该气瓶信息为合法信息，则通过该判断模块设置的判断信号输出端输出合法充气信号。控制模块与判断模块的判断信号输 出端相连接，并设置有控制信号输出端。当该判断信号输出端输出合法充气信号时，控制模块即通过该控制信号输出端输出充气控制信号。感应装置设置在充气枪本体上的卡装头内，与控制模块的控制信号输出端相连接，当感应装置接收到控制信号输出端输出的充气控制信号时，产生控制磁场，该控制磁场可以产生安培力，并且产生的安培力能够驱动驱动环沿着驱动环滑座滑动，进而实现打开阀门，液化气能够从该液化气充气枪的充气嘴进入该液化气瓶。
应用液化气瓶阀门时，将液化气瓶阀门竖直设置，不进行充气时卡接部卡接于卡孔上方，此时接杆上的第一密封件与插套通气孔的孔壁密封接触，实现该液化气瓶阀门的密封。充气时，使用液化气充气枪读取电子标签，若液化气瓶合格，则该液化气充气枪的控制磁场通电会产生足够的磁力吸引驱动环，使驱动环沿着驱动环滑座滑动，延伸部跟着滑动，直至接杆的卡接部脱离卡孔，此时接杆由于重力在通气孔中下移，接杆下移第一密封件不再与插套的通气孔内壁密封接触，而是第一密封件与通气孔的孔壁之间具有间隙，如此实现了气体的流通，气体可以从充气口流至阀体的出气口进入液化气瓶中。若该液化气瓶不合格时，液化气充气枪的控制磁场不会通电也不会产生足够的磁力，因此驱动环位置不变，第一密封件与通气孔内壁保持密封接触，通气孔处于封闭状态，故该液化气瓶无法被充气。从而实现自动的控制不给液化气瓶充气的过程，从而从根本上杜绝不合格液化气瓶的再使用，杜绝了非定点充装的现象。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
请参阅图1-图3，本申请提供的液化气瓶阀门包括阀体1、驱动环滑座2、驱动环4、第一线簧3、插套5、接杆6和第二线簧7。其中，阀体1的侧壁上设置有充气口8。驱动环滑座2嵌入阀体1侧壁上，且驱动环滑座2的轴线与阀体1的轴线之间具有夹角，并且驱动环滑座2与阀体1固定连接，为了防止液化气泄漏驱动环滑座2与阀体1应该密封固定连接。驱动环4具有相互固定连接的套环部42和延伸部43，其中套环部42套设在驱动环滑座2上，延伸部43由套环部42靠近阀体1轴线的端部向靠近轴线的方向延伸形成，且套环部42能够沿着其滑动即套环部42沿着驱动环滑座2滑动时驱动环4整体滑动，套环部42外壁上具有凸起的抵接部41，延伸部43具有卡孔。第一线簧3套设在套环部42上，并且第一线簧3的一端与套环部42外壁上的抵接部41相抵另一端与阀体1的内壁相抵，如此当套环部42受到充气枪的控制磁场产生的安培力时沿着驱动环滑座2滑动后会拉伸或者压缩第一线簧3，当充气枪的控制磁场产生的安培力消失时套环部42会由于第一线簧3的弹力复位，进而实现驱动环4的自动复位。
插套5固定在阀体1内部，且插套5具有通气孔，通气孔与充气口8连通，且通气孔与该阀体1的出气口连通，通气孔可以沿着阀体1的轴向设置。接杆6插设于插套5的通气孔内，并且接杆6能够沿着通气孔移动，即接杆6沿着通气孔的轴向移动，接杆6上固定有第一密封件61和能够卡在卡孔上方的卡接部62，卡接部62卡设在卡孔上方时第一密封件61与通气孔的孔壁密封接触，卡接部62脱离卡孔上方时第一密封件61与通气孔的孔壁之间具有间隙，其中卡接部62脱离卡孔上方时，接杆6会由于重力下降。第二线簧7套 设在接杆6上，并且第二线簧7的一端与卡接部62相抵另一端与插套5的内壁相对固定，如此当接杆6由于重力下降时，其卡接部62会压缩或者拉伸弹簧，如此可以通过第二线簧7的作用将接杆6复位。
应用本申请提供的液化气瓶阀门时，将液化气瓶阀门竖直设置，不进行充气时卡接部62卡接于卡孔上方，此时接杆6上的第一密封件61与插套5通气孔的孔壁密封接触，实现该液化气瓶阀门的密封。进行充气时，使用液化气充气枪扫描电子标签，若液化气瓶合格，则该液化气充气枪的控制磁场通电会产生足够的磁力吸引驱动环4，使驱动环4沿着驱动环滑座2滑动，延伸部43跟着滑动，直至接杆6的卡接部62脱离卡孔，此时接杆6由于重力在通气孔中下移，接杆6下移第一密封件61不再与插套5的通气孔内壁密封接触，而是第一密封件61与通气孔的孔壁之间具有间隙，如此实现了气体的流通，气体可以从充气口8流至阀体1的出气口进入液化气瓶中，实现充气。若该液化气瓶不合格时，液化气充气枪的控制磁场不会通电也不会产生足够的磁力，因此驱动环4位置不变，第一密封件61与通气孔内壁保持密封接触，通气孔处于封闭状态，故该液化气瓶无法被充气。从而实现自动的控制不给液化气瓶充气的过程，从而从根本上杜绝不合格液化气瓶的再使用，杜绝了非定点充装的现象，进一步保证了使用者的生命财产安全。
第二线簧7的上端与抵接部41相抵或者固定连接，第二线簧7的下端与插套5的内壁相对固定。具体的插套5的内壁可以设置为阶梯状，第二线簧7的下端抵在或者固定在阶梯状的内壁上。当然，第二线簧7的下端也可以直接固定在插套5的内壁上。插套5的通气孔的直径可以由上至下逐渐增加，如此接杆6下移时可以实现第一密封件61与通气孔的孔壁之间具有间隙。或者可以在通气孔的孔壁上设置凹槽，第一密封件61与凹槽上方的位置密封接触，接杆6下移时第一密封件61与凹槽的槽口位置接触，以此气体从凹槽中流通实现充气。接杆6的抵接部41位于其密封环的上方。驱动环的延伸部和套环部可以为一体式结构。
其中驱动环滑座2的轴向可以垂直于阀体1的轴向，且驱动环4沿着驱动环滑座2的轴向滑动，即驱动环4沿着垂直于阀体1的轴向的方向滑动。当然，驱动环滑座2的轴向可以与阀体1的轴向之间具有夹角，在此不作限定。
另外，通气孔的轴线和接杆6的轴线均沿着竖直方向设置，如此接杆6由于重力下降时阻力较小。此时驱动环滑座2的轴向可以沿着水平方向设置，驱动环4沿着水平方向滑动。
驱动环滑座2的远离阀体1轴线的端部与阀体1可以通过螺纹连接，以此实现驱动环滑座2与阀体1的固定连接。当然驱动环滑座2与阀体1也可以过盈配合或者焊接，且为了防止气体泄漏，驱动环滑座2与阀体1应该密封连接。阀体1的用于安装驱动环滑座2的安装孔的孔壁与驱动环滑座2之间具有间隙，驱动环和第一线簧3位于安装孔的孔壁与驱动环滑座2之间的间隙内。
具体的，液化气充气枪的控制磁场产生的磁力可以驱动驱动环4向靠近阀体1轴线的方向移动，此时延伸部43上还开设有让位孔，让位孔位于卡孔的靠近抵接部41的一侧且接杆6的卡接部62能够穿过让位孔，如此液化气充气枪的控制磁场产生的磁力驱动驱动环4向靠近阀体1轴线的方向移动时，接杆6上的卡接部62穿过让位孔下移，实现通气孔的通气。
当然，液化气充气枪的的控制磁场产生的磁力也可以驱动驱动环4向远离阀体1轴线的方向移动，在此不作限定。
另外，插套5外部还套设有第二密封件，如此保证了插套与阀体之间的密封连接。
为了防止磁力干扰，驱动环4可以为铝驱动环或者铜驱动环，即驱动环由铝或者铜制作形成。
需要说明的是，用于表明液化气瓶身份的电子标签可以设置在阀体1的外表面上。电子标签可以通过粘贴或者镶嵌的方式设置在阀体1的外表面上。电子标签可以为ID卡、RFID卡等非接触芯片，记录所对应的液化气瓶的详细信息。当然，电子标签还可以为二维码等。
另外，第一密封件61可以为O型密封圈，或者橡胶圈等。
图4为本申请实施例提供的一种液化气充气枪的结构图。
如图4所示，本实施例提供的液化气充气枪包括充气枪本体10和设置在充气枪本体10上的手动卡装装置14。
该手动卡装装置14包括拉杆141和连杆142，拉杆141的一端铰接在充气枪本体10上，连杆142的一端与该拉杆141的中部铰接在一起，另一端与安装有卡装头13的往复杆11连接。拉动该拉杆141可以带动该连杆142，连杆142拉动往复杆11在充气枪本体10的滑槽12中滑动，并带动其上的卡装头13将液化气瓶的阀门卡住，从而充气枪本体的充气嘴15与阀门的进气嘴紧密连接。
本实施例提供了一种液化气充气枪，包括充气枪本体和设置在该充气枪本体上的手动卡装装置14，手动卡装装置14能够替代气动卡装装置将该液化气充气枪卡装在液化气瓶的阀门上。由于无需配置气动装置及布置复杂的气路管道，从而降低了充气设备的复杂性，能够节省大量的投资，也相应地能够降低充气设备的复杂性，可靠性较高。
如图5所示，本实施例提供的控制系统20包括读取模块21、判断模块22、控制模块23和感应装置24。
读取模块21设置在充气枪本体10上，具体说设置在充气枪本体10的往复杆11内，用于读取设置在液化气瓶上的智能标签内的气瓶信息，该读取模块21利用接触式读卡器或者非接触式读卡器对智能标签中的气瓶信息进行读取。
判断模块22与该读取模块21相连接，用于对读取模块21读取到的液化气瓶信息进行判断，判断该液化气瓶信息是否为合法信息，即判断该气瓶信息所反映的该液化气瓶是否为合格的气瓶、是否为未经检验或已经报废的液化气瓶。如果该气瓶信息为合法信息，则通过该判断模块22设置的判断信号输出端221输出合法充气信号。
控制模块23与判断模块22的判断信号输出端221相连接，并设置有控制信号输出端231。当该判断信号输出端221输出合法充气信号时，控制模块23即通过该控制信号输出端231输出充气控制信号。
感应装置24设置在充气枪本体10上的卡装头13内，与控制模块23的控制信号输出端231相连接，当感应装置24接收到控制信号输出端231输出的充气控制信号时，产生控制磁场，该控制磁场用于打开液化气瓶上的阀门的限充装置即驱动驱动环沿着驱动环滑座滑动，这时如果打开阀门的进气阀门，液化气就能够从该液化气充气枪的充气嘴15进入该液化气瓶。
本实施例提供了一种液化气充气枪，包括充气枪本体和设置在充气枪本体上的控制系统，该控制系统包括用于读取液化气瓶的智能标签的气瓶信息的读取模块，与读取模块相连接、用于对判断该气瓶信息是否合法且当该气瓶信息为合法信息时从其判断信号输出端输出合法充气信号的判断模块，与该判断信号输出端相连接、用于根据该合法充气信号从其控制信号输出端输出充气控制信号的控制模块，与该控制信号输出端相连接、用于根据充气控制信号输出控制磁场的感应装置，该控制磁场用于打开该液化气瓶的阀门，这时打开阀门即可对该液化气瓶进行充气，而不合格的液化气瓶则不会打开限充装置，也就不会对其进行充气，从而能够杜绝不合格液化气瓶的继续使用。
本实施例的感应装置24包括电磁铁，该电磁铁包括圆环形线圈和设置在该圆环形线圈内的铁芯，为了增强磁性，该铁芯优选软磁铁氧体磁性。
本实施例的控制系统的电源装置25包括整流电路251和逆变电路252，
整流电路251用于输出低压直流电，为了保证安全、同时为了保证电磁铁能够产足够的磁性以打开智能角阀中的限充装置，该低压直流电的电压优选36伏。
逆变电路252与该整流电路251相连接，用于将低压直流电予以变换，并输出变换得到的低压交变电流，该低压交变电流用于输出到感应装置24的电磁铁中。逆变电路252包括四个连接成电桥的可控硅，如图9所示。逆变电路252的输出端与控制模块的电能输入端232相连接，当控制模块23接收到合法充气信号后，即将该低压交变电流作为充气控制信号输出到感应装置24，以驱动其中的电磁铁产生该控制磁场。
由于采用了交变电流代替直流电流驱动电磁铁产生控制磁场，能够降低发热量，能够避免因发热给燃气设备造成的危险。
为了对感应装置24进行保护，避免过流、过压或其他恶劣情况对感应装置24的伤害，本实施例还包括过流/过压保护装置26，如图10所示，该过流/过压装置26连接在控制模块23的控制信号输出端231与感应装置24之间。
如图7所示，本实施例提供的控制系统是在上一实施例提供的控制系统的基础上增设了报警装置27。
该报警装置27与判断模块22的报警信号输出端222相连接，当判断模块22对读取模块21输出的气瓶信息进行判断后发现该气瓶信息为非法信息，即该气瓶可能是未经检验或已经报废的气瓶时，输出报警信息，以提示操作人员采取措施，以避免该气瓶再次流入市场坑害消费者。报警信息可以是警报信息或者是语音提示信息。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的宗旨和范围，其均应涵盖在本申请的权利要求范围当中。
