Description

一种进水阀的防止小漏水装置 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小漏水装置。
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，止水垫澎涨产生背压力将进水口堵住，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容易出现故障，如排水阀出现关闭不严而慢慢漏水（小漏水），此时，出现进水阀持续进水，而水箱持续漏水的现象，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。
发明内容
本发明的目的在于提供一种进水阀的防止小漏水装置，以使水箱出现小漏水时，及时停止进水阀进水，节约水资源。
为达成上述目的，本发明的解决方案为：
一种进水阀的防止小漏水装置，安装于进水阀本体，包括摆臂、调节杆、浮筒、小水箱、虹吸管及配重浮力开关；摆臂枢接在进水阀本体上，摆臂的一端安装背压垫正对进水阀本体上的背压孔，摆臂的另一端与调节杆连接；浮筒安装在调节杆上置于小水箱中，小水箱安装在进水阀本体上；在小水箱上安装虹吸管，虹吸管上形成气孔；配重浮力开关安装在小水箱上，配重浮力开关包括相互独立的配重水腔及浮力水腔，配重水腔下端上设有漏水孔，配重水腔上端设有密封压片，密封压片与气孔相对，配重浮力开关控制气孔的开启与关闭。
进一步，配重浮力开关以上下滑动的方式安装在虹吸管上，配重浮力开关浮力大于自身重力状态下，配重浮力开关向上滑动而上浮，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，配重浮力开关向下滑动而下沉，密封压片堵住气孔而关闭虹吸管的气孔。
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。
进一步，在小水箱上枢接一杠杆，杠杆一端设置配重，另一端设置与与虹吸管排水口匹配的封片，封片与排水口相对，气泵抽吸虹吸管中空气状态下，封片封住排水口。
进一步，在小水箱上枢接一连杆，连杆一端与安装在小水箱中的浮筒相对，另一端连接拉丝，拉丝连接按钮，按压按钮拉动拉丝使连杆摆动，连杆一端按压浮筒下行将小水箱中的水经由虹吸管排出。
进一步，还包括接水盘及配重浮筒，接水盘安装在进水阀本体上，位于小水箱上方，接水盘上设置有溢水口，溢水口与小水箱相对，接水盘底部设有开口；配重浮筒安装在进水阀本体下端，配重浮筒包括水腔、浮力腔及固定座，水腔及浮力腔相互独立一体成型，水腔及浮力腔活动安装在固定座上，固定座安装在进水阀本体上，固定座上设置出水口，出水口通过管道与接水盘底部开口连接；水腔的重力大于浮力状态下，水腔堵住出水口，水腔的重力小于浮力状态下，水腔开启出水口。
采用上述方案后，本发明在正常进水时，水从供水管经进水阀本体进入水箱，水箱水位开始升高，水箱水位升高至小水箱最高位置时，水进入小水箱中，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，使背压垫关闭背压孔，止水垫澎涨产生背压力将进水口堵住，停止进水。
由于虹吸管上方设有气孔，止水后虹吸管的内外管水位一致，当正常排水时，由于进水阀小水箱外部的水位下降很快，配重浮力开关上面的配重水腔的水受到漏水孔（小孔）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在重力将虹吸管的开口堵住，进水阀水箱外部的水位下降，同时虹吸管设置在外部管道也下降，与内部的管道产生压力差，从而产生虹吸实现自动将进水阀小水箱的水排出（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，配重浮力开关受到浮力水腔的浮力作用，配重浮力开关的浮力大于自身重力，虹吸管的气孔开启，虹吸管不产生虹吸现象，而本发明小水箱底部不开口，因此小水箱的水位不下降，摆臂不偏转，背压孔不开启，进水阀不进水，节约水资源。此时，随着水箱水位慢慢下降，而配重浮力开关的配重水腔中的水慢慢从漏水孔漏出，配重水腔的水位与外部的水位基本相等，此时，配重浮力开关依然受到浮力水腔的浮力作用，配重浮力开关的浮力依然大于自身重力，虹吸管的气孔依然开启，虹吸管外面的管道水位也同时在下降；水箱水位继续慢慢下降，最终使得配重水腔中的水漏干净，配重浮力开关在重力作用下关闭虹吸管的气孔，此时，水箱水位下降较大，虹吸管外管道的水位也已降至接近开口，无法产生较大吸力，虹吸管不产生虹吸现象，小水箱的水位不下降，进水阀不进水，有效的防止了漏水的现象，节约水资源。

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12所示，本发明揭示的一种进水阀的防止小漏水装置，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及配重浮力开关7。
如图10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及图4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，虹吸管6上形成气孔63。
如图1及图4所示，配重浮力开关7安装在小水箱5上，配重浮力开关7包括相互独立的配重水腔71及浮力水腔72，配重水腔71下端上设有漏水孔711，配重水腔71上端设有密封压片712，密封压片712与气孔63相对，配重浮力开关7控制气孔63的开启与关闭，即配重浮力开关7浮力大于自身重力状态下，配重浮力开关7上浮，开启虹吸管6的气孔63，配重浮力开关7浮力小于自身重力状态下，配重浮力开关7下沉，密封压片712堵住气孔63，关闭虹吸管6的气孔63。
如图1、图3及图4所示，配重浮力开关7以上下滑动的方式安装在虹吸管6上，具体安装方式为：如图3所示，在虹吸管6上形成插条64，而在配重浮力开关7上形成插槽73，所述插条64***该插槽73中，使配重浮力开关7上下滑动活动安装在虹吸管6上。
配重浮力开关7浮力大于自身重力状态下，配重浮力开关7向上滑动而上浮，开启虹吸管6的气孔63，配重浮力开关7浮力小于自身重力状态下，配重浮力开关7向下滑动而下沉，密封压片712堵住气孔63，关闭虹吸管6的气孔63。
如图7及图8所示，配重浮力开关7也可以通过枢轴74枢接在小水箱5上，配重浮力开关7浮力大于自身重力状态下，配重浮力开关7向上摆动而上浮，开启虹吸管6的气孔63，配重浮力开关7浮力小于自身重力状态下，配重浮力开关7向下摆动而下沉，密封压片712堵住气孔63，关闭虹吸管6的气孔63。
本发明在正常进水时，水经进水阀本体1进入水箱，水箱水位开始升高，升高至小水箱5最高位置时，水进入小水箱5中，当小水箱5水位上升后，浮筒4受浮力作用而随之上升，带动摆臂2偏转，使背压垫21关闭背压孔11，水无法从进水阀本体1上的背压孔11进入水箱中，停止进水。
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7受到浮力水腔72的浮力作用，配重浮力开关7的浮力大于自身重力，虹吸管6的气孔63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7的配重水腔71中的水慢慢从漏水孔711漏出，此时，配重浮力开关7依然受到浮力水腔72的浮力作用，配重浮力开关7的浮力依然大于自身重力，虹吸管6的气孔63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71中的水漏干净，配重浮力开关7在重力作用下关闭虹吸管6的气孔63，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。
本发明小水箱5底部不开口，而在水箱小漏水时，虹吸管6不发生虹吸现象，小水箱5中的水较难排出，需要拆开进水阀，按压浮筒4使小水箱5中的水经虹吸管7排出，使得进水阀可以继续进水。
因此，本发明在虹吸管6下端形成吸气孔65，如图4及图9所示，吸气孔65通过管道与气泵66连接，气泵66的按压键与排水阀的按压键通用，按压气泵66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66为现有常规技术，其具体结构此处不赘述。
如图2及图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10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。
如图11及图12所示，本发明还包括接水盘8及配重浮筒9，接水盘8安装在进水阀本体1上，位于小水箱5上方，接水盘8上设置有溢水口81，溢水口81与小水箱5相对，接水盘8底部设有开口82；配重浮筒9安装在进水阀本体1下端，配重浮筒9包括水腔91、浮力腔92及固定座93，水腔91及浮力腔92相互独立一体成型，水腔91及浮力腔92活动安装在固定座93上，固定座93安装在进水阀本体1上，固定座93上设置出水口931，出水口931通过管道83与接水盘8底部开口82连接；水腔91的重力大于浮力状态下，水腔91堵住出水口931，水腔91的重力小于浮力状态下，水腔91开启出水口931。
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，配重浮力开关7随之迅速下降，配重浮力开关7的密封压片712将虹吸管6的气孔63堵住，此时，虹吸管6发生虹吸现象，小水箱中5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8，水进入接水盘8，由接水盘8底部的开口82通过管道83流入固定座93中，此时，由于水箱大漏水，浮力腔92失去浮力，水腔91在重力作用下堵住出水口931，使得水流管道83返流，由接水盘8溢水口81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。
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。
