所述导流部45外壁中部若干呈环形的小弧状凸起48，小弧状凸起48的弧度小于大弧状凸起47的弧度。
本发明的使用方法如下：
使用混水阀时，热水则会通过热水接头2流入至热水腔34内，然后依次通过热水孔5、止水垫片12下表面与密封台阶7之间的间隙流入至混水腔4内，一部分热水处于密封头10下方的空间内，另一部分热水则通过通水孔14向上流入至混水槽9内，与此同时，冷水则会通过该冷水接头3流入至冷水腔35内，然后通过冷水孔6流入至混水腔4内，再通过阀盖16下端面与活塞芯子8上表面之间的间隙流入至混水槽9内，与混水槽9内的热水混合，而冷水存在流动性，一部分冷水则会通过通水孔14向下流入至密封头10下方的空间内，与密封头10下方空间内的热水混合，此时热敏元件28被热水与冷水混合后的混合水包裹，热敏元件28实际上就是现有的感温包，能够根据实际温度发生相应的膨胀反应，随着热敏元件28被混合水包裹，热敏元件28能够第一时间感知到混合水的温度，此刻热敏元件28的膨胀程度刚好使活塞芯子8上的止水垫片12处于密封台阶7上方，止水垫片12与密封台阶7之间存在可供热水进入混水腔4内的热水，而在混水腔4内经热水与冷水混合的混合水最终则会通过与混水腔相贯通的出水接头流出，以供使用。
若是冷水接头3突然停止进水，热水接头2依旧不断往混水腔4内输送热 水，此刻混水腔4内的水温则会骤增，而热敏元件28则会第一时间感知到这股高温，并发生相应的膨胀反应，此时热敏元件28的上顶部2803则会通过顶杆29向上顶动导向柱24，随着导向柱24上移，推板23则会向上压缩上弹簧26，当上弹簧26被压缩至极限时，随着上顶部2803继续向上顶动，则会反推活塞芯子8向下移动，此时活塞芯子8带动止水垫片12向下移动，最终止水垫片12与密封台阶7相贴合，而密封台阶处于热水孔5下方，当密封台阶7被止水垫片12密封后，热水孔5内的热水便无法通过止水垫片12下表面与密封台阶7之间的间隙进入至混水腔4内，此刻热水孔5被堵塞密封，有效避免热水进入至混水腔4内再单独通过出水接头流出的情况。
综上所述可知，本发明可在冷水接头3突然停止进冷水时，通过止水垫片12自动对密封台阶7进行密封，即使热水接头2不断进热水，也无法通过热水孔5流入至混水腔4内，从而有效避免热水不与冷水混合直接通过出水接头流出导致烫伤的情况，在水温处于高温时实现自动切断热水，有效杜绝安全隐患，起到防烫的效果。
一字导向螺丝21下表面中部设有一字槽27，只需将一字螺丝刀卡于一字槽27内，便能够轻松将一字导向螺丝21从调温孔20下端孔口内旋出，而一字导向螺丝21的导向孔22能够对导向柱24起到导向作用，从而对热敏元件28的上顶部2803起到导向作用，避免上顶部2803在顶动时出现偏心导致活塞芯子8侧倾从而致使止水垫片12无法与密封台阶7紧密贴合密封影响密封效果的情况。
密封头10下表面外边沿设有一呈上宽下窄的锥面32，通水孔14下端孔口位于锥面32上，当热水依次通过热水孔5、止水垫片12下表面与密封台阶7之 间的间隙流入至混水腔4内时，热水则会直接冲击在锥面32上，由于锥面32呈上宽下窄状，能够起到一定的缓冲作用，避免热水直冲导致压力过大易产生噪音的情况，而锥面同时能够起到引导水流的效果，使水流顺着锥面32轨迹快速将热敏元件28围合在内，有效提高热敏元件28的感温效率。
通水孔14通过一吸力口33与密封槽11相贯通，当混水槽9与通水孔14内充满水时，随着热水不断进入至混水腔4内，此时通水孔14内的压力则会小于活塞芯子8外的压力，吸力口33位置产生负压，将止水垫片12牢牢的吸附在密封槽11内，从而有效提高止水垫片12嵌于密封槽11内时的稳固性，与此同时，随着止水垫片12被吸附在密封槽11上，能够有效起到静音以及防止水锤的效果。
当热水通过热水腔34流入至热水孔5内时，必然会经过左过滤网筒39，左过滤网筒39能够对热水中的杂质进行有效过滤，保证热水的洁净程度，需要对左过滤网筒39进行清洗时，只需将左堵头37从左螺孔36内向上旋出，便可轻松将左过滤网筒39从热水腔34内抽出进行清洗；当冷水通过冷水腔35流入至冷水孔6内，必然会经过右过滤网筒43，右过滤网筒43能够对冷水中的杂质进行有效过滤，保证冷水的洁净程度，需要对右过滤网筒43进行清洗时，只需将右堵头41从右螺孔40内向上旋出，便可轻松将右过滤网筒43从冷水腔35内抽出进行清洗。
热水孔5与冷水孔6内皆设有一止回阀芯44，热水孔5内的止回阀芯44能够有效避免混水腔内的混合水通过热水孔5向着热水腔34内回流的情况，冷水孔6内的止回阀芯44能够有效避免混水腔4内的混合水通过冷水孔6向着冷水腔35内回流的情况。
旋转头19呈正六边形，通过六角扳手能够轻松对旋转头19进行旋动，当旋转头19旋转时，调温阀杆18随之发生旋转，当调温阀杆18顺着中螺孔15轨迹向上移动时，活塞芯子8随之上移，此时止水垫片12下表面与密封台阶7之间的间隙变大，热水进水的流量变大，混合水的水温随之上升，在寒冬季节使用混水阀时，热水自身的温度受天气温度影响则会比正常天气低，此时则可通过增加热水的进水流量使混合水的温度依旧能够满足实际所需，在实际使用过程中，可通过调温阀杆18精准调节出水接头的出口温度，可在供热水达到最高温的情况下，出口温度也不会超过49℃，并能够获得最大流量。
密封台阶7呈上宽下窄状，止水垫片12下表面设有一套于密封头10外的导流部45，导流部45呈上宽下窄状，密封台阶7的台阶面与导流部45外壁之间形成一增流通道46，因此增流通道46呈倾斜状，增流通道46上端端口直接与热水孔5相对并相贯通，中间不存在任何阻碍，一旦止水垫片12上移不再贴合于密封台阶7上，热水孔5内的热水则会通过增流通道46快速进入至混水腔内，由于导流部45呈上宽下窄状，因此导流部45外壁不会对热水孔5内端孔口进行覆盖，从而有效保证热水进入至增流通道46内的流量，且在密封台阶7同样呈上宽下窄状的情况下，密封台阶7的台阶面与导流部45外壁之间的增流通道宽度最大，能够进入更大流量的热水，从而在不改变出水温度、高温切断效果的情况下，能够有效增加热水的进水流量，避免冷水流量增大时热水流量无法自动增大导致混水后的水温无法达到实际所需温度的情况。
导流部45外壁从上至下设有若干呈环形的大弧状凸起47，大弧状凸起47的存在能够在增流通道46内形成多道均匀分布的阻碍，从而一定程度上减少热水通过增流通道46流入至混水腔4内的流量。
导流部45外壁中部若干呈环形的小弧状凸起48，小弧状凸起48同样能够形成多道均匀分布的阻碍，且小弧状凸起48的分布更细密，由于小弧状凸起48的弧度小于大弧状凸起47的弧度，因此小弧状凸起48形成的阻力远大于大弧状凸起47形成的阻力，能够进一步阻挡热水的流动，进一步减少热水通过增流通道46流入至混水腔4内的流量，由此可知，选择不同结构的止水垫片12，便能够实现热水不同的进水流量，实现热水流量的自动调节，从而适应不同冷水的进水流量。
为了进一步提高热水流动的顺畅性以及流量，可在导流部45上部外壁设置一个呈环形的辅助凹面49，辅助凹面49弯曲方向与导向部外壁弯曲方向相反，与此同时，可在相邻的大弧状凸起47设置呈环状的过渡凹面50，过渡凹面50的弧度小于辅助凹面49的弧度。
