Description

一种防卡涩温控阀 技术领域
本发明涉及一种卫浴设备中的温控阀，具体是一种具有防卡涩功能的温控阀。
背景技术
温控阀是卫浴设备中常见的部件，通常采用热敏元件实时监控水温，并利用热敏元件的伸缩变化来控制活塞进水量；同时，还有相关的调节部件，使温控阀可以根据需求在不同的温度予以保护。
但由于调节部件的存在，整个阀门会被水体携带的杂质以及形成的水垢影响，毕竟调节部件中的活动零件会因为这些沉积物质而卡涩，乃至失效。同时，由于水压的存在，调节部件会受到比较大的压力，其寿命难以保证。所以，如何避免调节部件中水垢、杂质的沉积，同时又要减小水压对调节部件的影响，成为设计这类温控阀的必然需求。
发明内容
针对以上的需求，本发明提出一个防卡涩温控阀，其技术方案如下：
一种防卡涩温控阀，包括一个阀腔和其内的热敏组件与调节组件；所述阀腔包括进水口和出水口；所述热敏组件具有控制所述阀腔内壁上进水量的活塞；所述调节组件通过其内的一压帽轴向紧密接触所述热敏组件；所述调节组件包括：
一个压帽套，与所述热敏组件同轴设置；所述压帽固定于所述压帽套的一端，并且在此压帽的一端该压帽套具有一段等横截面的滑动段；该滑动段外径小于所述阀腔在此处的内径；以及
一固定圈，环状，其外圈液密封固定于所述阀腔内壁，内圈与所述滑动段液密封配合。
作为本技术方案的优选者，可以有如下方面的改进：
一较佳实施例中，所述固定圈的内圈与外圈均有密封环。
一较佳实施例中，所述压帽套按轴向还包括一限位段和一螺纹段；所述滑动段与螺纹段分别位于该压帽套的两端，所述限位段位于所述滑动段与螺纹段之间；所述限位段具有与所述阀腔内壁轴向滑动配合的引导面。
一较佳实施例中，所述阀腔的一端轴向固定一旋杆，该旋杆在所述阀腔内螺纹活动配合于所述螺纹段；该旋杆在所述阀腔外具有一调节柄。
一较佳实施例中，所述压帽套具有一个通孔，该通孔在所述压帽套底端具有一内缘；该通孔在所述压帽套的顶端具有内螺纹；另有一螺钉固定配合于此内螺纹，且在所述通孔内通过一个上弹簧连同所述内缘固定所述压帽的位置。
一较佳实施例中，所述热敏组件包括：
一热敏杆，套接固定于所述活塞；以及
一下弹簧，该下弹簧一端固定于所述阀腔，另一端紧靠所述活塞；该下弹簧的应力方向与所述上弹簧相反。
一较佳实施例中，所述进水口在所述阀腔内壁轴向分列于所述活塞的两端位置；所述活塞具有连通两面的混水孔。
本发明带来的有益效果是：
固定圈与阀腔内壁、滑动段均液密封配合，使调节组件的活动部位不受水路的影响，从而避免了水垢、杂质等的沉积造成调节组件卡涩；同时，相对于滑动段，固定圈承担了水路中大部分的压力，使压帽套以及旋杆受水压影响小，延长了使用寿命。
附图说明
以下结合附图实施例对本发明作进一步说明：
图1是本发明实施例带剖视的立体图；
图2是图1实施例剖面示意图。
具体实施方式
如图1所示，本发明一种具有防卡涩功能的温控阀，其阀体1内部具有一个柱形的阀腔，除了旋杆2的手柄部分以外，几乎所有的阀芯组件都位于阀腔内。调节组件包括旋杆2、压帽套3、压帽4、螺钉5、上弹簧6和固定圈7；热敏组件包括了热敏杆8、活塞9和下弹簧10。以上所有部件均同轴设置，这是这类温控阀的特色。在热敏杆8对水温的监视下，活塞9受控轴向移动控制水流输入，同时调节组件调节柄设置热敏组件的温控参数。
活塞9中段具有连通其两面的混水孔；上弹簧6的应力远大于下弹簧10，所以压帽套3通过压帽4对热敏杆8顶端的压迫只会导致下弹簧10发生形变。
图2是图1实施例剖面示意图。该图展示了调节组件以及水路的一些细节。图1中的压帽套3包括轴向的三部分，至下而上分别是滑动段31、限位段32和螺纹段33；滑动段31活动套接于固定圈7内，而该固定圈7是固定在阀腔的内壁。限位段32与阀腔的内壁活动配合，具有与所述阀腔内壁轴向滑动配合的引导面，可以轴向移动，而被限制不可相对阀腔旋转；螺纹段33与旋杆2底端的螺纹活动配合，用于调节压帽套3在阀腔内的轴向位置。压帽套3具有一个通孔35，压帽4、上弹簧6依次设置在通孔35内，其顶端旋接一螺钉5；在滑动段31末端还具有一个内缘34，该内缘34限定了压帽4的位置。
固定圈7在阀腔内限定了一密闭空间，压帽套滑动段31的上部及限位段32均位于密闭空间内，使调节组件的活动部位不受水路的影响，从而避免了水垢、杂质等的沉积造成调节组件卡涩；同时，相对于滑动段32，固定圈7承担了水路中大部分的压力，使压帽套3以及旋杆2受水压影响小，延长了使用寿命。
旋杆2轴向固定在阀腔的顶端，在阀腔内螺纹活动配合于所述螺纹段33；该旋杆2在所述阀腔外具有一调节柄23。
热敏组件的热敏杆8套接固定于活塞9，其顶端插入压盖4；下弹簧10一端固定于所述阀腔，另一端紧靠所述活塞9；下弹簧10的应力方向与上弹簧6相反。
阀体1具有轴向分列的两类进水口，本例中分别是冷进水口20和热进水口21，从图中的虚线箭头可见该二进水口的水流示意；在整个阀门的底部是出水口11。当实际使用中，来自冷、热进水口20、21的水进入阀腔时，必然对阀腔内壁造成一定的压强。从短线箭头的示意可知，压强沿短线箭头作用于调节部件，该方向大部分压力作用在固定圈7上，而压强在滑动段31产生的压力很小，使旋杆2受到的压力就相应很小。
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
工业实用性
本发明一种防卡涩温控阀，其调节组件的活动部位处于固定圈界定的一密闭空间，避免了水垢、杂质等的沉积造成的卡涩；同时，相对于滑动段，固定圈承担了水路中大部分的压力，使压帽套以及旋杆受水压影响小，延长了使用寿命。
