Description

一种马桶进水阀及其控制方法 技术领域
本发明涉及一种流体阀门，特别是用于马桶水箱的液位控制阀门，和相应的控制方法。
背景技术
在抽水马桶进水控制装置中，带有浮筒的液位控制阀门已经被广泛应用。该类阀门利用浮筒的浮力，根据水箱水位控制其进水，自动补充水箱水量。其中，阀门的开启和关断是通过抬杆装置，使浮筒的上下位移控制到针阀、托盘、止水胶垫等机构所完成。
由于此类阀门直接连接在城市生活用水管道上，其进水压力和稳定性受到整个供水网络的影响，如果水压过高或者不够稳定，则水流流经阀门时会对阀门造成冲击，由于液位控制阀门都运用到包括针阀在内的多个连动机械结构件，此冲击会不同程度地影响到这些结构件的寿命，同时不可避免地产生大量的噪音，影响家居或公共环境生活。本申请人早期就有一个已授权的针阀的方案CN2421475Y，内中涉及一种采用针阀的进水阀，由于其针阀是活动套接于止水胶垫，止水胶垫采用软质材料，所以在受水压控制的运动过程中，其针阀孔间隙不稳定，所以止水过程会带来噪音和震动，因此，如何地设计一种可靠、安静更加人性化的阀门成为一个待解决技术问题。
发明内容
针对以上阀门寿命和噪音的问题，本发明公开一种马桶的进水阀，其技术方案是：
一种马桶进水阀，包括阀门体、进水管、带止水胶垫的止水装置、浮筒装置、抬杆装置和出水管,所述止水装置还包括：
一止水座，位于所述出水管前端，其开口与所述止水胶垫端面配合；
一托盘，连接于所述止水胶垫，位于所述止水座相对于止水胶垫的相反侧；
一针阀，紧固于托盘，位于所述止水胶垫相对于托盘的相反侧；以及
一背压腔，为一具有泄压孔的腔体，容纳所述托盘和针阀，该背压腔上具有套接所述针阀的针阀孔。
作为同类方案的另一种，可如下实现：
一种马桶进水阀，包括阀门体、进水管、带止水胶垫的止水装置、浮筒装置、抬杆装置和出水管,其特征在于所述止水装置还包括：
一止水座，位于所述进水管末端，其开口与所述止水胶垫端面配合；
一托盘，连接于所述止水胶垫，位于所述止水座相对于止水胶垫的相反侧；
一针阀，紧固于托盘，位于所述止水胶垫相对于托盘的相反侧；以及
一背压腔，为一具有泄压孔的腔体，容纳所述托盘和针阀，该背压腔上具有套接所述针阀的针阀孔。
作为本技术方案的优选者，可作如下改进：
以上两种同类方案，其针阀按其轴向可分为两段，分别是：
一契合段，其横截面形状与所述针阀孔契合；以及一间隙段，其横截面形状与所述针阀孔不契合而具有明显间隙；按照针阀如此的两段形式，一种实现形式是：针阀的契合段横截面为圆形，所述间隙段外表面具有沿针阀轴向延伸至所述托盘的槽。另一种实现形式是：所述针阀契合段横截面为圆形，所述间隙段横截面也为圆形，该间隙段横截面直径比所述契合段横截面直径小。
在所述针阀孔外，进水流入口可具有一带滤网的过滤器。此过滤器滤网进水口朝向可设定为垂直于来自所述进水管的水流矢量方向。
第一种方案所述进水管外侧可具有一同轴气囊腔，所述气囊腔底部包括一环形弹性气囊。
第一种方案所述进水管底部流体腔可具有回转的结构。
两种方案的所述托盘可为碗状，且其外侧面为一圆柱侧面。
根据以上二段式的针阀结构，本实用新型的控制方法包括一个稳态和两个动态：
稳态：所述泄压口堵塞，所述背压腔只有一个进水口就是所述针阀与针阀孔的间隙；所述背压腔内存满水，所述止水胶垫在所述背压腔内受到水压的压强等于其外部压强，止水胶垫静止并堵塞所述止水座，相应地所述托盘和针阀也静止，针阀契合段位于所述针阀孔内；
动态一：在稳态的基础上，所述泄压口开启，从而所述背压腔内的存水迅速从泄压口流出，其内部压强迅速减小；此时所述止水胶垫在所述背压腔内受到水压的压强明显小于其外部压强，因而外部水压迫使止水胶垫连同托盘与针阀朝所述背压腔内缩回，随着缩回行程的增大，针阀先是契合段位于所述针阀孔内，其次行进到间隙段；此动态一可归纳为止水胶垫开启的过程；
动态二：在动态一的基础上，所述泄压口堵塞，因进水管的水从所述针阀孔与针阀的缝隙流入所述背压腔，所述背压腔内存水开始增加；随着水增加的过程，背压腔内压力增大，所述托盘推动所述止水胶垫朝背压腔外扩展，同时带动针阀在针阀孔内相对于动态一反向行进，从而针阀在针阀孔内先是间隙段，后是契合段，这个变化使得背压腔内的进水速度减小，使背压腔内增压的速度减小，也就缓解了托盘压迫止水胶垫堵塞止水座的速度；此动态二可归纳为止水胶垫阻尼闭合的过程，一直持续到稳态为止。
本发明带来的有益效果：
1．托盘和针阀固定连动，针阀与针阀孔的间隙为背压腔进水口，此进水口位于止水胶垫和托盘的相反侧，活动套接于硬质针阀孔中，其背压腔进水与阀门止水部件远离，并且针阀与针阀孔的间隙稳定，故工作时减小了噪音和震动。
2．由于采用了二段式针阀结构，使得针阀在工作循环中具有阻尼关闭的过程，从而极大地缓解了止水时造成的冲击和震动，减小各部件的碰撞磨损和工作噪音。
3．过滤器滤网的存在以及滤网的横向进水结构使得进入针阀装置的水流得到缓冲和过滤：一方面水压得到缓解，另一方面水流因冲击含带的各种固体杂质被垂直过滤且冲洗掉，使得针阀工作更为可靠、安全。
4．进水管外部同轴的气囊腔在整个阀门进水时，对流体具有分流减压的效果。
5．在进水管在底部的流体腔采用回转结构约束水流矢量旋进；此旋转行进的水路使得水流中大部分冲击能量被妥善分解和吸收，极大程度地避免了因为冲击带来的震动和噪音。

如图1，图2和图3所示，为本发明的实施例一概览。1是阀门的本体，托盘2、止水胶垫3、针阀4、针阀盖5构成止水装置主要部件，其中针阀盖5还具有泄压孔52； 6是弹性气囊，7是过滤器，8是滤网；9是螺头，10是进水管；11是抬杆，12是上胶垫，121是泄压口，13是浮筒，14是出水管，15是调节杆，16是止水座；图中的箭头都示意水流方向。
图4，图5，图 6，图7和图8用立体爆炸图的方式更清楚地表现阀门本体1内部结构。图4和图5中，模块A包括了止水装置的主要部件，模块B包括了进水管部分的主要部件。其中，模块A的分解图如图6所示，背压腔主体部分为针阀盖5，托盘2固定套接针阀4的间隙段一端， 托盘2的前端穿过且固定于止水胶垫3顶端；而针阀4的契合段插入针阀盖5的针阀孔51，虽然形状契合，但可以自由滑动且非液密封。模块A中的止水胶垫3、托盘2和针阀4的关系在图8中从另一个视角体现；模块B的分解图如图7， 弹性气囊6套接于进水管10的底部，再将螺头9套接在进水管上；进水管10底部具有回转的流体腔101。
图9和图10分别是两种针阀安装在托盘2上的示意，图9所示的针阀4其契合段41横截面为圆形，间隙段42包含了周向分布的槽；而图10所示的针阀4其契合段41横截面也为圆形，间隙段42横截面同样为圆形，其直径比契合段41小。
以下根据水流的流经顺序来说明阀门工作状态。如图3所示，首先来自水网的水流进入螺头9， 此处分为两路，一路从进水管10外到达气囊腔，在其内碰触气囊6后停止或返回；另一路通过进水管10进入阀门本体1，此时又分为两路，一路为干路，另一路为控制支路：
干路：此路水流在进水管10进入进水管流体腔101， 再旋进到达止水胶垫3，对止水胶垫3形成一个逆向水压，此水压方向与进水管10中的水流方向完全相反；
控制支路：此路经过滤网8进入过滤器7内腔，从而穿过针阀4与针阀孔51（图6）之间的间隙，到达包括针阀盖5的背压腔，给予托盘2一个顺向水压，此水压方向与进水管10中水流方向一致。
若此时，整个水箱中的液位使得浮筒13上升到关闭位，此时浮筒通过调节杆15控制上胶垫12堵住其对应的泄压口121，使针阀盖5所在的背压腔中的顺向水压与干路中的逆向水压压强一致，由于止水胶垫2两面水压的有效面积设计差异，此时其顺向水压力比逆向水压力大，从而托盘2往出水方向压迫止水胶垫3，止水胶垫3堵塞止水座16，止住水流从干路通往出水管；
若此时，整个水箱中的液位下降，使得浮筒13下降，上胶垫12不再堵住泄压口121，从而使针阀盖5所在的背压腔中的顺向水压迅速减小，而干路中的逆向水压不会变化，所以止水胶垫3与托盘2均在逆向水压作用下后退，开启止水座16，从而干路水流顺利沿出水管14管壁旋转流下。
自此，浮筒13在下降之后，出水管会一直出水使水箱液位上升，直到上升到关闭位。此时，上胶垫12再次堵住泄压口121，针阀盖5所在的背压腔内顺向水压开始回升；该过程中，来自进水管10的干路水流经过针阀4和针阀孔51的间隙，压迫托盘2开始朝出水方向移动，逐渐挤压止水胶垫3；此过程针阀4与针阀孔51间先是间隙段，其水流速较大；当托盘2不断移动时，带动针阀4也在针阀孔51内移动，针阀4契合段会逐渐进入针阀孔51，替代原来间隙段的位置，从而水流流速减小，缓解顺向水压增大的趋势，使托盘2缓慢压迫止水胶垫3，直至止水胶垫3封住出水座16。针阀4的二段式结构决定了此分步的止水方式，减小整个止水过程中阀门体内部的震动和噪音。
实施例二：
图11所示是本发明的另一中实施例，与实施例一相比，相同的是止水装置本身包括托盘2、止水胶垫3、针阀4和背压腔52的相对位置和功能；所不同的是整个止水装置相对于进、出水管的方向与实施例一相反，因为进水管10其末端就是止水座16，止水座16靠接止水胶垫3并可被止水胶垫3堵塞；出水管14连接止水座16外侧的腔体；
干路：此路水流在进水管10进入进水管流体腔，对止水胶垫3形成一个逆向水压，此水压方向与进水管10中的水流方向完全相同；
控制支路的水流经过通道102进入过滤器7，再经过针阀4进入背压腔52；当托盘2压迫止水胶垫3向下堵塞止水座16时，进水管10的水流被关闭；当泄压口121打开减小背压腔52内的水压时，止水胶垫3受进水管10的水压而压迫托盘2上升，打开止水座16，从而出水管14与进水管10连通，水流流出（与进水管进水方向相反）；针阀4依然与托盘2同步移动。
综上，任何类似本技术方案采用的水流分路控制止水的方式，并依据此作出变化修饰的，都在本发明的保护范围内。
工业实用性
本发明的阀门本体将水流被分为两路，一路为干路，另一路为控制支路：
干路的水流到达止水胶垫，对止水胶垫形成一个逆向水压；控制支路的水流穿过针阀与针阀孔之间的间隙，到达包括针阀盖的背压腔，给予托盘一顺向水压。针阀与针阀孔的间隙稳定，故工作时减小了噪音和震动。由于采用了二段式针阀结构，使得针阀在工作循环中具有阻尼关闭的过程，从而极大地缓解了止水时造成的冲击和震动，减小各部件的碰撞磨损和工作噪音。
