Description

一种缸式燃气阀切断器
技术领域
本发明涉及燃气安防装置技术领域，具体指一种缸式燃气阀切断器。
背景技术
随着社会的发展，人们的物质文化生活水平得到了显著的提高，燃气灶作为一种改善人民生活条件的家用能源设备，无论在城市还是农村都是得到了广泛的应用。但在使用燃气的过程中，因燃气泄漏废气等原因造成的燃气爆炸，中毒等意外事故时有发生，给人们生命和财产安全带来了严重的威胁，燃气泄漏报警器能有效监测环境中可燃气体或毒性气体的浓度，并且能自动切断燃气供应，防止燃气继续泄漏，起到安全防范的作用。现有市面的燃气泄漏报警装置款式多样，其安全机制在于浓度监测值超标时能够发出信号报警，或者切断燃气管路并启动排风系统降低浓度。这些报警装置存在结构复杂的问题，燃爆风险的控制机制存在缺陷，难以快速抑制和排除燃气泄漏风险。
因此，现有技术还有待于改进和发展。
发明内容
本发明的目的在于针对现有技术的缺陷和不足，提供一种结构合理、无需特定驱动源、稳定可靠的智能化缸式燃气阀切断器。
为了实现上述目的，本发明采用以下技术方案：
本发明所述的一种缸式燃气阀切断器,包括燃气管道上的球阀和减速基座，所述球阀的阀轴上设有被动齿轮，减速基座上设有滑槽，减速基座一侧设有活塞缸和控制器，活塞缸的输出轴前端设有齿条，齿条穿设于滑槽内且齿条与被动齿轮啮合传动；所述活塞缸上设有与其作工腔连通的三通电磁阀，三通电磁阀的一端与燃气管道连通；所述控制器与三通电磁阀电连接，控制器上设有可燃气浓度传感器、电源和报警器。
根据以上方案，所述控制器上设有复位键，活塞缸上设有与其活动腔连通的排气电磁阀，复位键用于控制三通电磁阀的排气端和排气电磁阀。
根据以上方案，所述齿条与被动齿轮之间设有减速齿轮。
根据以上方案，所述控制器内设有无线模块，控制器通过无线模块连接外部设备和智能终端进行信息交互。
本发明有益效果为：本发明结构合理，可燃气浓度传感器检测值超标时，三通电气阀接入燃气管道获得管道压力，活塞驱动齿条带动球阀关闭燃气管道，无需辅助动力简化整体结构；控制器通过无线模块可连接外部设备和智能终端进行信息交互，控制器发出报警提示信息，整体结构无需辅助动力稳定可靠，可有效降低燃气泄漏风险。

具体实施方式
下面结合附图与实施例对本发明的技术方案进行说明。
如图1所示，本发明所述的一种缸式燃气阀切断器,包括燃气管道上的球阀1和减速基座2，所述球阀1的阀轴上设有被动齿轮11，减速基座2上设有滑槽21，减速基座2一侧设有活塞缸3和控制器4，活塞缸3的输出轴前端设有齿条31，齿条31穿设于滑槽21内且齿条31与被动齿轮11啮合传动；所述活塞缸3上设有与其作工腔连通的三通电磁阀32，三通电磁阀32的一端与燃气管道连通；所述控制器4与三通电磁阀32电连接，控制器4上设有可燃气浓度传感器41、电源42和报警器43；所述三通电磁阀32连接球阀1外端的燃气管道，当室内存在可燃气浓度超标时，控制器4启动三通电磁阀32的进气端，活塞缸3内获得燃气管道内压进入驱动齿条31在滑槽21内滑动，带动被动齿轮11从而关闭球阀1，避免燃气继续泄漏造成风险增大；同时报警器43发出报警信息，控制器4具有交互接口从而与外部终端进行信息交互，提醒用户存在可燃气泄漏的情况。
所述控制器4上设有复位键44，活塞缸3上设有与其活动腔连通的排气电磁阀33，复位键44用于控制三通电磁阀32的排气端和排气电磁阀33；所述复位键44用于启动控制器4的复位程序，球阀1的再次开启需要排除泄漏隐患后，通过复位键44开启三通电磁阀32排气端和排气电磁阀33，使活塞缸3回复自由活动，当球阀1完全开启后，活塞和齿条31回到初始位置，控制器4再次关闭三通电磁阀32和排气电气阀33使活塞缸3的内腔压力保持平衡，从而使球阀1处于自锁状态。
所述齿条31与被动齿轮11之间设有减速齿轮22，齿条31由活塞缸3提供动力，而活塞缸3的动能取自燃气管道内压，通过减速齿轮22的减速齿比可降低球阀1驱动所需动能。
所述控制器4内设有无线模块45，控制器4通过无线模块45连接外部设备和智能终端进行信息交互，所述智能终端可以是燃气管理监控中心或用户智能手机APP，存在燃气泄漏情况时控制器4启动报警器43的同时，通过无线网络发送报警信息，从而提醒用户及早排除泄漏隐患。
以上所述仅是本发明的较佳实施方式，故凡依本发明专利申请范围所述的构造、特征及原理所做的等效变化或修饰，均包括于本发明专利申请范围内。
