Description

一种固定在排水阀上的进水阀 技术领域
本发明涉及马桶水箱进水阀技术领域，特别涉及一种固定在排水阀上的进水阀。
背景技术
当前常见的马桶水箱内大都设有进水阀和排水阀，进水阀连通家庭用水管网，将家庭用水管网内的水流引入马桶水箱，对马桶水箱进行补水，排水阀连通至马桶座，将马桶水箱内储存的水排向马桶座，对马桶座进行冲洗。
排水阀上一般都设有溢流管，溢流管从排水阀底部向上延伸一定高度，并在溢流管顶部开设溢流口，溢流口通过溢流管通至马桶座，防止因进水阀失效导致马桶水箱内的水溢出。
进水阀通常分为底进水式、侧进水式，底进水式进水阀在阀体下方设置有与马桶水箱底部固定的竖向支撑管，支撑管在马桶水箱内向上延伸一定高度，底进水式进水阀的支撑管内设有进水管、出水管，进水管通过进水口连通家庭用水管网，出水软管通过出水口通向马桶水箱；侧进水式进水阀则在阀体侧部设有与马桶水箱侧壁固定的横向支撑管，横向支撑管通过进水口连通家庭用水管网，侧进水式进水阀则在阀体下方还需要再设置出水软管，出水软管通过出水口通向马桶水箱。
进水阀与排水阀互相协作，实现马桶水箱的进水、排水，但分别独立设置的进水阀与排水阀，空间占用较大，且不利于材料的节省、成本的控制。

如图3、4、5所示，所述背压阀6包括止水盖61、止水垫62、第一转动臂63、第二转动臂64、背压垫65，所述止水盖61卡接在安装口55内，所述止水垫62的一侧抵在所述止水口531上，所述止水垫62的另一侧与止水盖61扣合形成背压腔66，所述止水垫62设有连通所述进水腔53与背压腔66的过水孔67，所述止水盖61上设有连通背压腔66与外界的背压孔68；当所述背压孔68被封堵时，进水腔53内的水流在水压的作用下通过过水孔67进入背压腔66，背压腔66水压上升，水压推动所述止水垫62封堵止水口531，进水腔53停止向排水腔54进水，当背压孔68被打开时，背压腔66与外界连通，背压腔66内的水压降低，进水腔53内的水压推动止水垫62打开止水口531，实现进水，即通过背压孔68的开启或关闭，即可实现对阀体5进水腔53与排水腔54间水路通断的控制；
所述第一转动臂63平行于止水盖61端面，并通过第一转动轴631枢接在止水盖61 一侧，在所述止水盖61上设置第一枢孔611，所述第一转动轴631可转动地穿设在第一枢孔611内，第一转动轴631将第一转动臂63分隔为长臂632与短臂633，长臂632端部为自由端；第二转动臂64平行于止水盖61端面，通过位于第二转动臂64一端的第二转动轴641枢接在止水盖61另一侧，在所述止水盖上设置第二枢孔612，第二转动轴641可转动地穿设在第二枢孔612上，第二转动臂64另一端跨过背压孔68外侧与第一转动臂63短臂633滑动连接，第二转动臂64与第一转动臂63形成具有开口的半封闭环，箍在所述止水盖61两侧，第二转动臂64设有与背压孔68位置相对应的背压垫65；当推动第一转动臂63带动第二转动臂64绕轴旋转，带动背压垫65开启或关闭背压孔68；第二转动臂64与第一转动臂63通过滑柱642与滑槽634配合连接，滑柱642在滑槽634中滑动，使得第二转动臂64与第一转动臂63能够一起运动，向上推动第一转动臂63的长臂632时，第一转动臂63绕轴旋转，第一转动臂63的短臂633向下运动，短臂633端部设置的滑槽634带动第二转动臂64的滑柱642向下滑动，第二转动臂64绕第二转动轴641旋转，进而第二转动臂64靠近止水盖61，背压垫65封闭背压孔68。

如图1、4、6所示，为使安装在溢流管上的进水阀能够根据不同的马桶水箱进行高度调节，本部分提供了一种进水阀高度调节装置，利用溢流管4向上延伸的高度，在溢流管上设置高度调节装置，将进水阀连接在该高度调节装置上，进而调节进水阀在马桶水箱内的高度，具体地，所述溢流管4包括固定管41、活动套管42，所述活动套管42为外表面光滑的圆柱形管，所述接水槽56下方设置的环形套接部564内径不小于所述活动套管42的外径，所述环形套接部564可转动地套接在所述活动套管42上方；所述固定管41外壁沿固定管竖直阵列有定位齿411，所述每相邻的两个定位齿411间设有一个凸块412，所述定位齿411由固定管41底部阵列至固定管41顶部，所述活动套管42内壁设有与定位齿411卡合的卡合齿421，所述卡合齿421上设有与所述凸块412卡接的卡槽422，所述活动套管42可转动地套接在固定管41上，所述活动套管42转动使卡合齿421旋入定位齿411，在卡合齿421旋入定位齿411后，凸块412与卡槽422卡接，将活动套管42与固定管41周向固定，反向旋转活动套管42，使定位齿411旋出卡合齿421，此时活动套管42可沿固定管41上下移动，移动至待调整高度后，再将卡合齿421旋入该高度上的定位齿411，卡合齿421与定位齿411卡接，活动套管42被固定在固定管41的一定高度上，高度调整完成，所述阀体5通过其接水槽56上设置的环形套接部564与活动套管42的套接、随活动套管42一同沿所述固定管41上下移动，进而所述阀体5通过定位齿411与卡合齿421的卡合调整在马桶水箱内的高度。
如图3、4、7(a)、7(b)所示，所述阀体5上设有限位部565，所述浮力控制机构2还包括水箱21、浮筒22、浮筒螺杆23、水箱螺栓24；
所述水箱21沿竖直方向设有通孔211，所述水箱21通过通孔211活动套接在所述溢流管4上，所述水箱21能够沿溢流管4上下滑动、周向旋转，所述水箱21上方开口，所述浮筒22落于水箱21内，水箱21下设有只供出水的单向阀25，所述单向阀25为现 有技术，本实施例中不在进行详细阐述；
所述限位部565上设有浮筒螺杆限位孔566，所述浮筒螺杆23穿过浮筒螺杆限位孔566，限制浮筒螺杆23的径向移动，所述浮筒螺杆23下部设有螺杆螺纹段，所述浮筒22设有与螺杆螺纹段相配合的浮筒连接孔221，浮筒螺杆23通过浮筒连接孔221螺接浮筒22，所述的浮筒螺杆23上设有卡槽，所述卡槽卡接止水滑块233，所述止水滑块233沿竖直方向设置止水滑槽234，所述止水盖61沿竖直方向设有止水滑轨613，所述止水滑槽234滑动卡接在止水滑轨613上，所述止水滑块233连接所述第一转动臂63的长臂632端，所述浮筒22在所述水箱21内上下运动，带动浮筒螺杆23上下运动，浮筒螺杆23带动第一转动臂63、第二转动臂64箍紧或放松在止水盖61两侧，进而控制背压垫65封堵或开启背压孔68；
所述限位部565上设有水箱螺栓限位孔567，所述水箱螺栓24穿过水箱螺栓限位孔567，所述限位部565通过水箱螺栓限位孔567限制水箱螺栓24的径向移动，所述水箱螺栓24下方设有与螺杆螺纹段旋向相反的螺栓螺纹段，所述水箱21上设有与水箱螺栓24上的螺栓螺纹段相配合的水箱链接孔212，所述水箱螺栓24下部通过水箱链接孔212螺接水箱21，所述阀体5上设有水箱螺栓连接槽568，所述水箱螺栓24上部穿过水箱螺栓连接槽568可转动地连接在阀体5上；
所述浮筒螺杆23与水箱螺栓24之间啮合传动，故浮筒螺杆23与水箱螺栓24转动方向相反，因螺杆螺纹段与螺栓螺纹段的螺纹旋向相反，转动浮筒螺杆23或者水箱螺栓24，使浮筒22和水箱21能够同时向同一个方向运动。
如图3、8(a)、8(b)、9(a)、9(b)所示，本部分提供了一种补水装置，补水装置通常由进水阀上的补水通道通过管连接导通至排水阀，本实施例中将补水装置的补水通道直接开设在溢流管上方，并且直接在补水通道上设置补水条调节机构，使结构更加紧凑，具体地，所述阀体5下方设有与排水腔54相通的补水通道58，所述补水通道58直接设置在溢流口1上方，所述补水通道58设有与补水通道58垂直相交的补水 旋钮安装孔584，所述补水旋钮581可转动地安装在补水旋钮安装孔584内，将补水通道58的进水端与出水端分隔，所述补水旋钮安装孔584在补水通道58的两侧设有密封圈590，所述密封圈590环绕补水旋钮581侧壁，以防止补水旋钮581与补水旋钮安装孔584连接处漏水，所述补水旋钮581一端延伸出补水通道58外，与控制补水旋钮581旋转的手柄582连接，在本实施例中，所述手柄582延伸至所述阀体5的接水槽56外表面，所述手柄582在接水槽56外表面延伸有拨杆585，所述接水槽56外表面设有最大水位限位块586、最小水位限位块587，所述补水旋钮581在补水通道58内设有调节孔583，所述调节孔583的轴线与所述补水通道58的轴线位于同一平面，旋转补水旋钮581改变调节孔583与补水通道58的错位角度，当调节孔583与补水通道58位于同一轴线时，此时为补水比例最大，拨杆585与最大水位限位块586相抵，当调节孔583与补水通道58垂直时，此时为补水比例最小，拨杆585与最小水位限位块587相抵，所述手柄582在所述接水槽56的外表面处设有刻度线588，所述接水槽56的外表面设有指向刻度线588的指针589，在调节补水量大小时，拨动补水旋钮581，观察指针589所指向的刻度线588位置，即可获知补水通道58开启的比例，所述补水旋钮581在背离手柄582的一端设有与补水旋钮安装孔584卡合的弹性卡接齿580，将所述补水旋钮581从所述接水槽56外表面插入补水旋钮安装孔584，手柄582与阀体5的接水槽56表面相抵时，弹性卡接齿580与补水旋钮安装孔584的另一端卡合，即可将补水旋钮581进行轴向的固定，本案中的补水旋钮不限于上述的具体结构，同样可采用其他便于操作的旋钮形状。
如图3、图9、图10所示的进一步的实施例中，所述阀体1上的排水腔54分为上下两部分，下部的排水腔一端安装有密封塞59，所述密封塞59呈“U”形，所述密封塞59“U”形开口朝上安装在位于下部的排水腔一端，将位于下部的排水腔54与进水腔53分隔，所述下部的排水腔设有延伸至阀体5顶部的导水口595，所述位于上部的排水腔与所述进水腔53连通于止水口531，所述上部的排水腔设有连通至阀体顶部的防虹吸 口594，所述防虹吸口594与导水口595上方设有防虹吸腔593，所述防虹吸腔593内设有防虹吸垫591，所述防虹吸垫591放置在防虹吸口594上，所述防虹吸腔593上方扣合有防虹吸盖592，所述防虹吸盖592卡接设置在阀体5外壁，所述防虹吸盖592在防虹吸垫591上方设置进气口598，当水从防虹吸口594流出时，会在防虹吸腔593产生水压，上顶防虹吸垫591脱离防虹吸口594并封堵进气口598，所述防虹吸腔593将防虹吸口594与导水口595导通，当水从防虹吸口594停止流出时，防虹吸腔593内水压消失，防虹吸垫591下落封堵防虹吸口594并打开进气口598，导水口595通过进气口598与外界连通，此时若进水管产生负压，因下部的排水腔与外界导通，则进气口598进气进行压力平衡，水流不会从马桶水箱倒吸回排水腔。
具体实施例2：
如图2所示，所述溢流管4上不设有活动套管42，所述固定管41外表面为光滑的柱面，所述环形套接部564与所述水箱21上的通孔211直接套接在固定管41上。
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。
