Description

一种进水阀的防止大漏水装置 技术领域
本发明涉及进水阀技术领域，尤其是指一种进水阀的防止大漏水装置。
背景技术
现有技术中，进水阀通常包括进水管、顶盖、背压垫、摆臂、浮筒和小水箱，进水管的下端安装在水箱的供水管上，顶盖安装在进水管的上端，顶盖上开设背压孔，摆臂的中段枢设在顶盖上，摆臂的一端正对背压孔，并安装背压垫，摆臂的另一端与浮筒的调节杆连接，浮筒安装在小水箱中，而小水箱安装在进水管上，各构件之间设有保证水密性的密封件。
使用时，当小水箱水位下降，浮筒受重力作用而随之下降，带动摆臂偏转，使背压垫开启背压孔，水从供水管流经进水管、顶盖及背压孔进入水箱中，实现进水。当小水箱水位上升后，浮筒受浮力作用而随之上升，带动摆臂偏转，使背压垫重新关闭背压孔，止水垫产生背压力澎涨，堵住进水口，实现停止进水。
所述进水阀在小水箱的底部设置有漏水孔，水箱排水水位下降后，小水箱中的水通过漏水孔进入水箱中，使得浮筒失去浮力，受重力作用而随之下降，带动摆臂偏转，开启背压孔，实现进水。然而，水箱在使用一段时间后出现故障无法关闭，如排水阀出现大漏水，此时，出现进水阀持续进水，而水箱持续大漏水的现象，造成水资源浪费。
因此，本发明人对进水阀的结构进行改进，以便在出现上述情况时及时停止进水阀进水，本案由此产生。

进一步，配重浮力开关通过枢轴枢接在小水箱上，配重浮力开关浮力大于自身重力状态下，配重浮力开关向上摆动而上浮，开启虹吸管的气孔，配重浮力开关浮力小于自身重力状态下，配重浮力开关向下摆动而下沉，密封压片堵住气孔而关闭虹吸管的气孔。
进一步，在虹吸管下端侧部形成吸气孔，吸气孔通过管道与气泵连接，按压气泵抽吸虹吸管中空气，虹吸管泄压而小水箱中的水经由虹吸管排出。

采用上述方案后，本发明小水箱底部不开口，水箱持续大漏水时，水箱水位迅速下降，安装在小水箱上的虹吸管发生虹吸现象，小水箱中的水全部排出，此时，摆臂背压垫开启进水阀本体上的背压孔，水经进水阀本体进入水箱，进水阀进水。
在进水阀本体上安装接水盘，水进入接水盘，由接水盘底部的开口与管道连接，此时，由于水箱大漏水，水腔失去浮力，水腔中装满水，水腔堵住管道下端出口，使得水流通过管道返流，由接水盘溢水口进入小水箱，而小水箱底部不开口，使得小水箱水位上升，安装在小水箱中的浮筒上升，带动摆臂偏转，使背压垫关闭背压孔，止水垫澎涨产生背压力将进水口堵住，实现停止进水，节约水资源。
进水阀需重新进水时，按压进水阀的浮筒使浮筒受压将小水箱中的水排出，小水箱水位下降，浮筒受重力作用而随之下降，带动摆臂偏转，使背压垫开启背压孔，进水阀可以继续进水。

具体实施方式
以下结合附图及具体实施例对本发明做详细描述。
参阅图1至图9，本发明揭示的一种进水阀的防止大漏水装置，安装于进水阀本体1，包括摆臂2、调节杆3、浮筒4、小水箱5、虹吸管6、接水盘7及配重浮筒8。
如图6所示，摆臂2枢接在进水阀本体1上，摆臂2的一端安装背压垫21正对进水阀本体1上的背压孔11，摆臂2的另一端与调节杆3连接。浮筒4安装在调节杆3上置于小水箱5中，小水箱5安装在进水阀本体1上，所述结构为现有结构。
如图3所示，在小水箱5上安装虹吸管6，虹吸管6的进水口61置于小水箱5的底部，而虹吸管6的排水口62置于小水箱5外部，进水口61的高度大于排水口62的高度，进水口61位于排水口62之上，且排水口62的高度低于小水箱5的底部，所述为虹吸管6常规原理。
如图1及图2所示，接水盘7安装在进水阀本体1上，位于小水箱5上方，接水盘7上设置溢水口71，溢水口71与小水箱5相对，接水盘7底部设置开口72。
配重浮筒8安装在进水阀本体1下端，配重浮筒8包括水腔81及浮力腔82，水腔81及浮力腔82相互独立一体成型，水腔81及浮力腔82安装在进水阀本体1下端，接水盘7底部开口72通过管道84与配重浮筒8连接，水腔81重力大于浮力状态下，水腔81堵住管道84下端出口，水腔81重力小于浮力状态下，水腔81开启管道84下端出口。
如图7所示，配重浮筒8还包括固定座83，固定座83安装在进水阀本体1下端，固定座83上设置与管道84下端出口相通的出水口831，水腔81及浮力腔82以上下滑动方式活动安装在固定座83上，所述上下滑动方式为：在浮力腔82上安装支架821，支架821套接在固定座83出水口831上，在支架821下端设置卡扣822，在固定座83中设置卡条832，水腔81堵住固定座83出水口831状态下，卡条832下端与卡扣822之间形成间隔，水腔81开启固定座83出水口831状态下，卡扣822抵靠在卡条832下端而限制水腔81及浮力腔82上移。管道84可以为软管。
如图10至图12所示，配重浮筒8另一实施例结构示意图，配重浮筒8还包括密封座85，密封座85设置在水腔81及浮力腔82一侧，配重浮筒8枢接在管道84下端，水腔81的重力大于浮力状态下，水腔81及浮力腔82向下摆动而下沉，密封座85堵住管道84下端出口，水腔81的重力小于浮力状态下，水腔81及浮力腔82向上摆动而上浮，水腔81开启管道84下端出口。管道84可以为硬质伸缩管道。
本发明小水箱5底部不开口，水箱持续大漏水时，水箱水位迅速下降，安装在小水箱5上的虹吸管6发生虹吸现象，小水箱5中的水全部排出，摆臂2背压垫21开启进水阀本体1上的背压孔11，水经进水阀本体1进入水箱，进水阀进水。
在进水阀本体1上安装接水盘7，水进入接水盘7，由接水盘7底部的开口72流入管道84中，此时，由于水箱大漏水，水腔81失去浮力，水腔81中装满水，水腔81堵住管道84下端出口，使得水流通过管道84返流，由接水盘7溢水口71进入小水箱5，而小水箱5底部不开口，使得小水箱5水位上升，安装在小水箱5中的浮筒4上升，带动摆臂2偏转，使背压垫21关闭背压孔11，水无法进水阀本体1进入水箱中，实现停止进水，节约水资源。
进水阀需重新进水时，按压浮筒4将小水箱5中的水经虹吸管6排出，使小水箱5水位下降，浮筒4下降，带动摆臂2偏转，使背压垫21开启背压孔11，进水阀可以继续进水。
因此，本发明在虹吸管6下端侧部形成吸气孔63，如图3所示，吸气孔63通过管道与气泵64连接，气泵64的按压键与排水阀的按压键通用，按压气泵64抽吸虹吸管6中空气，虹吸管6泄压而小水箱5中的水经由虹吸管6排出，实现进水阀继续进水。所述气泵64为现有常规技术，其具体结构此处不赘述。
如图3所示，为进一步将虹吸管6中的空气吸干净，本发明在小水箱5上枢接一杠杆51，杠杆51一端设置配重511，另一端设置与与虹吸管6排水口62匹配的封片512，封片512与排水口62相对。按压气泵66抽吸虹吸管6中空气时，杠杆51封片512封住虹吸管6排水口62，使得虹吸管6中空气抽吸较为干净，而虹吸管6排水时，杠杆51另一端远离排水口62。
如图5所示，本发明也可以在小水箱5上枢接一连杆52，连杆52一端与安装在小水箱5中的浮筒4相对，另一端连接拉丝（图中未示出），拉丝连接按钮，所述按钮可以与排水阀按压键通用，按压按钮拉动拉丝使连杆52摆动，连杆52一端按压浮筒4下行将小水箱5中的水经由虹吸管6排出，实现进水阀继续进水。
所述解决水箱大漏水时，关闭进水阀使其不进水，以节约水资源，本发明通过以下技术方案解决水箱小漏水（渗水）时，关闭进水阀使其不进水的技术问题。
本发明还包括配重浮力开关9，如图1及图2所示，配重浮力开关9安装在小水箱5上，配重浮力开关9包括相互独立的配重水腔91及浮力水腔92，配重水腔91下端上设有漏水孔911，而虹吸管6上端设置气孔65，如图8所示，配重水腔91上端设有密封压片912，密封压片912与气孔65相对，配重浮力开关9控制气孔的开启与关闭。
如图8所示，配重浮力开关9以上下滑动的方式安装在虹吸管6上，配重浮力开关浮9力大于自身重力状态下，配重浮力开关9向上滑动而上浮，开启虹吸管6的气孔65，配重浮力开关9浮力小于自身重力状态下，配重浮力开关9向下滑动而下沉，密封压片912堵住气孔65，关闭虹吸管6的气孔65。具体安装方式为：在虹吸管6上形成插条66，而在配重浮力开关9上形成插槽93，所述插条66插入该插槽93中，使配重浮力开关9上下滑动活动安装在虹吸管6上。
如图9所示，配重浮力开关9也可以通过枢轴94枢接在小水箱5上，配重浮力开关9浮力大于自身重力状态下，配重浮力开关9向上摆动而上浮，开启虹吸管6的气孔65，配重浮力开关9浮力小于自身重力状态下，配重浮力开关9向下摆动而下沉，密封压片912堵住气孔65，关闭虹吸管6的气孔65。
当正常排水时，由于进水阀小水箱5外部的水位下降很快，配重浮力开关5上面的配重水腔91的水受到漏水孔911的限制流出来的水较慢，因此在排水的过程产生内外水位，瞬间克服下面浮力转换成重力将虹吸管6的开口堵住，产生虹吸实现自动将进水阀小水箱5的水排出（不需要带解锁装置）。
水箱持续小漏水（渗水）时，水箱水位慢慢下降，此时，配重浮力开关9受到浮力水腔92的浮力作用，配重浮力开关9的浮力大于自身重力，虹吸管6的气孔65开启，虹吸管6不产生虹吸现象，而本发明小水箱5底部不开口，因此小水箱5的水位不下降，摆臂2不偏转，背压孔11不开启，进水阀不进水，节约水资源。
随着水箱水位慢慢下降，而配重浮力开关9的配重水腔91中的水慢慢从漏水孔911漏出，此时，配重浮力开关9依然受到浮力水腔92的浮力作用，配重浮力开关9的浮力依然大于自身重力，虹吸管6的气孔65依然开启，进水阀不进水。
水箱水位继续慢慢下降，最终使得配重水腔91中的水漏干净，配重浮力开关9在重力作用下关闭虹吸管6的气孔65，此时，水箱水位下降较大且下降较慢，无法产生较大吸力，虹吸管6依然不产生虹吸现象，小水箱5的水位依然不下降，进水阀依然不进水，节约水资源。
本发明还公开一种进水阀的防止大漏水装置，安装于进水阀本体1，包括摆臂2、调节杆3、浮筒4、小水箱5及连杆52；摆臂2枢接在进水阀本体1上，摆臂2的一端安装背压垫21正对进水阀本体1上的背压孔11，摆臂2的另一端与调节杆3连接；浮筒4安装在调节杆3上置于小水箱5中，小水箱5安装在进水阀本体1上。在小水箱5上枢接一连杆52，连杆52一端与安装在小水箱5中的浮筒4相对，另一端连接拉丝，拉丝连接按钮，按压按钮拉动拉丝使连杆52摆动，连杆52一端按压浮筒4下行将小水箱中的水排出，实现进水阀继续进水。
以上所述仅为本发明的较佳实施例，并非对本案设计的限制，凡依本案的设计关键所做的等同变化，均落入本案的保护范围。
