Description

一种转子式液体温度混合调节阀 技术领域
本发明涉及液体温度调节阀， 特别是一种通过随机调节不同温 度液体的混合比例来控制混合后液体温度的转子式液体温度混合调 节阀。 背景技术
现有的液体温度混合调节阀， 一般用作水温调节， 采用手动方 式的混合调节岡是把冷水管和热水管接通阀体。 通过手动搡作来调 节冷、 热水的混合比例， 从而达到调节出水温度的目的， 此种方法 的不足之处在于： 一方面调节精度不高； 另一方面是当进水温度改 变时， 要用人工不断地调节， 才可以保证出水温度接近设定值。 而 一些自动式的液体温度混合调节阀， 则往往采用双金属片、 记忆金 属或液体膨胀式结构来调节冷、 热液体的比例， 它们既是感应元件， 也是执行元件， 由此而产生的问题是： 调节不方便， 反应较为緩慢， 调节精度不高， 由于不能通过电量来改变阀体的预置温度， 因而很 难与外围设备联动来完成自动化控制， 同时， 这类结构的混合调节 阀也难于保证能长期稳定工作并具有较长的工作寿命。 发明的公开
本发明的目的在于提供一种转子式液体温度混合调节阀， 它不 但能通过电量的变化来连续改变液体混合后的预置温度， 而且调节 迅速、 精度高、 工作稳定。
本发明的另一个目的还在于提供一种转子式液体温度混合调节 阀， 它具有结构简单、 体积小、 功耗小、 工作力大。
本发明所提供的一种转子式液体温度混合调节阀， 包括阀壳及 其内所设的冷液输入管， 热液输入管及其混合液输出管， 设于输出 管内的温度传感器及控制电路， 在阀壳侧部固装有用于控制冷、 热 液体比例的无挡铗转子式电磁铁， 该电磁铁的转子式衔铗转轴外延 端固装有调节块， 该调节块位于所述冷液榆入管口端面与热液输入 管口端面之间， 调节块随着衔铁转轴转动， 其两侧面能分别与阀壳 内腔的冷液输入管口端面和热液输入管口端面贴合， 或在两端面之 间作任意角度的摆动或停留， 衔铁转轴设在阀壳上的轴承外壳定位 孔内并装有椽胶密封圈。 所述无档铁转子式电磁铁装有复位弹簧。 其一端固定在铗芯或支架上， 另一端装在转子式衔铁一侧或衔铗转 轴延伸部所紧固的臂杆上。 该复位弹簧一端设有调节螺丝， 用于修 正各种因素所造成的系统误差。 附图的简要说明
以下结合附图详细说明本发明的较佳实施例， 其中：
图 1 是无挡铁转子式电磁铁的吸力特性曲线图， 图中 F 表示吸 力， δ表示衔铁的行程， 吸合终点为 0 ;
图 2是本发明一个实施例的结构示意图；
图 3是图 2去掉阀壳及温度传感器后的无挡铗转子式电磁铗结 构示意图；
图 4是图 2所示阀壳部分的 Α-Α剖视图。 实现本发明的最佳方式
参见图 2、 图 3 、 图 4所示， 本发明的转子式液体温度混合调 节阀用于热水器， 它的调温液体是水， 该调节阀由阀壳 6、 安装在 阀壳内腔 2混合液输出管上的温度传感器 8与控制电路及安装于阀 壳 6—侧的无挡铁转子式电磁铁组成。 阀壳 6 内腔 2设有冷进水管 17、 热进水管 18及混合水出水管 16， 在阀壳 6—侧平面上开有衔 铁转轴轴承外壳 15 的定位孔， 电磁铁的转轴轴承外壳 15及转轴 9 延伸部就安装定位于此， 并在该定位孔内转轴 9上装有橡胶密封圈 14。 无挡铁转子式电磁铁通过其铁芯 5及支架 4固装在阀壳 6—侧 平面上， 其转子衔铗 1 1 与支架 4之间设有复位弹簧 12 , 在该复位 弹簧 12上还装有调节螺丝 13。 在转轴 9外延端装有调节块 1 , 该 调节块 1位于冷进水管口端面 3和热进水管口端面 10之间，调节块 1 随着转轴 9转动， 其两侧面能分别贴合于冷进水管口端面 3和热 进水管口端面 10 , 这是调节块 1 的起点和终点状态。 在无挡铁转子 式电磁铁不通电工作的情况下， 由于复位弹簧 12的作用， 调节块 1 其中一个侧面会贴合在冷液输入管口端面 3 或热液输入管口端面 10。 当控制电路通电后， 设于混合液输出管内的温度传感器 8输出 电信号与预置温度的预设电压进行比较， 输出一个可控制的电量给 线圈 7 , 电磁铁工作， 调节块 1在冷、 热进水管口端面 3 、 10之间 作任意角度的摆动或停留， 即通过改变电磁铁线圈电流大小， 调节 块在上述冷、 热输入管口端面之间摆动， 实现按比例调节冷、 热水 流量， 从混合出水管 16流出的混合水温度恒定在预置温度范围内。
