Description

一种泄气阀及利用气压开启的马桶水箱排水阀 技术领域
本发明涉及气压推动开启的马桶水箱排水阀，特别涉及一种气压开启的马桶水箱排水阀及其泄气阀。
背景技术
传统的马桶水箱排水阀是通过按压按键推动摆杆，摆杆提升排水阀的内芯管与半排限位装置或全排限位装置的挂钩相卡配，内芯管下端的封水片离开阀体的出水口，开启排水阀的半排或全排排水功能，当水箱水位下降，半排限位装置的半排浮桶或全排限位装置的全排浮桶失去浮力时，内芯管失去半排限位装置有限或全排限位装置的挂钩支撑，内芯管与挂钩的卡配关系解除而下落，内芯管下端的封水片与阀体的出水口重新密封，排水关闭。
以上可见，传统的马桶水箱排水阀的按键、摆杆、内芯管三者之间是一种机械杠杆传动结构，需要人们手动按压按键才能实现内芯管的提升，而现在国家提倡人们追求高品质的美好生活，人们希望通过电子感应实现马桶水箱排水阀的开启，而不用去按压安装在马桶水箱上的排水阀按键，既省力方便，又避免不同的人们去按压排水阀按键而发生交叉感染。
目前市场上出现了气压推动开启的马桶水箱排水阀，通过电子感应开关、控制器与气泵电连接，气泵与伸缩气囊通过气管连接，气管上连接有电磁泄压阀，需要排水时，人们在电子感应开关上方挥手，电子感应开关将感应信号发送到控制器，控制器打开气泵，气泵给伸缩气囊充气，伸缩气囊膨胀推顶设在排水阀的内芯管上的提拉盖，从而带动内芯管的上升，当内芯管上升到与 排水阀的半排限位装置或全排限位装置的挂钩相卡配时，电磁泄压阀打开，伸缩气囊中的空气通过电磁泄压阀而泄出，伸缩气囊利用自身的弹性回缩恢复原状，给内芯管下落让位，内芯管下端的封水片离开阀体的出水口，开启排水阀的半排或全排排水功能，当水箱水位下降，半排限位装置的半排浮桶或全排限位装置的全排浮桶失去浮力时，内芯管失去半排限位装置有限或全排限位装置的挂钩支撑，内芯管与挂钩的卡配关系解除而下落，在内芯管下落之前，内芯管下端的封水片与阀体的出水口重新密封，排水关闭。
以上可见，伸缩气囊需要通过电磁泄压阀来泄压，一旦电磁泄压阀损坏失效，伸缩气囊要么不能被充气，要么不能被放气，致使排水阀不能正常使用，况且电磁泄压阀成本高，又有耗电的缺点，本发明人研发出一种利用机械结构来实伸缩气囊泄压的泄气阀。
发明内容
本发明提供一种气压开启马桶水箱排水阀的泄气阀，该泄气阀性能可靠、成本低、无需耗电。

如图4、5、6所示，同理，如果电子感应开关(图示视出)感应到全排排水时，将全排排水有感应信号发送到控制器(图示视出)，控制器打开气泵(图示视出)，气泵通过全排气管89给右侧全排用的伸缩气囊8充气，右侧全排用的伸缩气囊膨胀8推顶设在排水阀的内芯管4上右侧的全排提拉盖432，从而带动内芯管4的上升，封水片42离开排水阀的出水口51，开启排水阀的全排排水功能，因为，半排限位装置61高于全排限位装置62,内芯管4的中部的全排卡点45上升到达全排挂钩623的位置时，半排卡点44已超过与半排挂钩613的位置，半排挂钩613对半排卡点44不起卡制作用，当内芯管4的中部的全排卡点45与全排限位装置62的全排挂钩623相卡配时，又因为推块3的左推部31高于右推部32,左推部31先与左侧泄气阀9的上挡止24的下部的斜面25接触，推块3的推抵上挡止24的下部的斜面25，弹性件21受压缩，滑动块2在泄气阀9的阀座1上既向上移动又横向偏移，滑动块2的限位凸块28退出阀座1上的限位挡止14，滑动块2的底部的密封垫29离开泄气嘴13，打开泄气嘴13,由于左侧半排用的伸缩气囊8并没有充气，左侧半排用的伸缩气囊膨胀8并没有推顶内芯管4上左侧的半排提拉盖431,左侧半排用的伸缩气囊8保持原始状态，而此时，推块3的右推部32推抵右侧全排用的泄气阀9的上挡止24的下部的斜面25，弹性件21受压缩，滑动块2在阀 座1上既向上运动又横向偏移，滑动块2的限位凸块28退出阀座1上的限位挡止14，滑动块2的底部的密封垫29离开泄气嘴13，从而打开泄气嘴13,右侧全排用的伸缩气囊8通过气管81、泄气嘴13进行泄气，右侧全排用的伸缩气囊8利用自身的弹性回缩恢复原状，给内芯管4下落让位；当全排排水完毕后，全排限位装置62的全排浮桶621失去浮力下落，带动全排转动架622转动，全排挂钩623脱离对内芯管4的中部的全排卡点45的卡制，内芯管4下落带动封水片42重新密封排水阀的出水口51时，推块3下压右侧的泄气阀9的下挡止23，弹性件21推抵滑动块2的限位凸块28重新插入阀座1上的限位挡止14的限位孔中，滑动块2的底部的密封垫29堵住泄气嘴13，从而将泄气嘴13进行密封，气泵与右侧全排用的伸缩气囊8之间形成封闭的气路，为下次排水开启作准备。
