Abstract

A thermostatic cold and hot water valve comprises internally three layers of valve core sheets in order as follows: a fixed sheet (8) for inflow of cold and hot water and outflow of mixed water; a rotating sheet (7) for controlling outflow ratio of cold and hot water; and a movable sheet (6) for controlling outflow of mixed water. In operation, the outflow areas of cold and hot water may be changed by rotating a knob on a valve body, thereby controlling the water temperature. A movable ceramic disc (5) is correspondingly provided on the movable ceramic sheet (6). A control rod (2) is provided in a movable sleeve (4) on an upper portion of the movable disc (5). An operating handle (1) is connected with the control rod (2). The communication of the water outlet of the movable ceramic sheet (6) is controlled by lifting and pressing the operating handle, thereby controlling the amount of water flow. The thermostatic cool and hot water valve has the advantages in that the cost can be reduced greatly, and the cold and hot water can be mixed adequately and uniformly.

恒温冷热水阀 所属技术领域  Thermostatic hot and cold water valve
本实用新型涉及一种能够灵活调节水温的温水阀。  The utility model relates to a warm water valve capable of flexibly adjusting water temperature.
背景技术 Background technique
目前， 大家在家庭、 公共场所洗浴间中使用的温水阔是用一个手柄开启同时调节温度和 流量， 洗浴过程中关闭水阀再次开启时， 往往难以调到原先所用的合适温度， 或出现水温忽 高忽低的情况， 给使用带来不方便。 现常用温水阀内部由一个动陶瓷片和一个定陶瓷片， 动 陶瓷片在旋转和移动过程中对冷热水出水口覆盖的比例并非均匀变化， 导致有时它稍微旋转 一点， 水温就改变很多。 现新出现的热水恒温调节阀是通过各种感温材料以及多个阀芯等复 杂结构构成， 其造价成本很高， 不适合广大人群的需求。  At present, the warm water used in the bathing rooms of homes and public places is opened with a handle and the temperature and flow rate are adjusted. When the water valve is closed again during the bathing process, it is often difficult to adjust to the proper temperature used, or the water temperature suddenly appears. The situation of high and low is inconvenient for use. Nowadays, the inside of the warm water valve is composed of a moving ceramic piece and a fixed ceramic piece. The proportion of the moving ceramic piece covering the hot and cold water outlet during the rotation and movement does not change uniformly, which causes it to rotate slightly at a time, and the water temperature changes a lot. The newly developed hot water thermostatic regulating valve is composed of various temperature sensing materials and multiple valve cores and other complex structures, and its cost is high, which is not suitable for the needs of the general public.
发明内容 Summary of the invention

The proportion of hot and cold water flow, the moving ceramic piece that controls the flow of water, can change the coverage area of the water outlet on the rotating ceramic piece. When the water outlet on the two moving ceramic piece is connected, the water valve is opened, and the water outlet on the two ceramic pieces When not at all, close the water valve. At this time, the rotating ceramic piece located between the fixed ceramic piece and the moving ceramic piece can only rotate within a certain range (preferably in the range of 130° to 150°), and the moving ceramic piece located above can only move within a certain range. .
在阀芯壳上， 旋转陶瓷片安装的位置处有相应的缺口， 缺口的大小决定了旋转陶瓷片的 旋转范围， 定位圈里围伸进缺口与旋转陶瓷片固定， 外围与带有相应缺口的阀体外壳上的环 形无盖调温旋钮固定， 人在旋转旋钮的时候就能改变冷热水出水面积比例进而控制水温。  On the valve core casing, there is a corresponding notch at the position where the rotating ceramic piece is mounted. The size of the notch determines the rotation range of the rotating ceramic piece, and the notch and the rotating ceramic piece are fixed in the positioning ring, and the periphery and the corresponding notch are provided. The annular coverless thermostat knob on the valve body casing is fixed, and when the knob is rotated, the proportion of the hot and cold water outlet area can be changed to control the water temperature.
移动陶瓷片上有相应的移动盘， 移动盘上部移动轴套内有控制杆， 操作手柄与控制杆相 连， 人通过对手柄的抬起和按压， 可控制移动陶瓷片出水口的接通， 进而控制水流量。  There is a corresponding moving disk on the moving ceramic piece. The upper part of the moving plate has a control rod in the moving sleeve. The operating handle is connected with the control rod. The person can control the opening of the water outlet of the moving ceramic piece by lifting and pressing the handle, and then control Water flow.
本实用新型的有益效果是， 与现有双阀芯产品相比能大大节约成本和空间构造， 与现有 单阀芯产品相比， 既可以准确地控制好所需求的温度， 使冷热水充分混合均匀， 又能灵活地 控制水流速， 使用过程中一次调好水温， 多次开闭水阀后都能保持原先的温度不变。 附图说明  The utility model has the beneficial effects that the cost and the space structure can be greatly improved compared with the existing double valve core products, and the required temperature can be accurately controlled compared with the existing single valve core products, so that the hot and cold water can be accurately controlled. It can be fully mixed evenly, and it can flexibly control the water flow rate. The water temperature can be adjusted once during use, and the original temperature can be maintained after opening and closing the water valve multiple times. DRAWINGS

旋转陶瓷片 7 位于定陶瓷片 8 与移动陶瓷片 6 中间， 且三个陶瓷片紧密贴近。 旋转陶瓷 片 7 边沿有凹槽， 定位圈 11 上具有凸柱， 使旋转陶瓷片 7 能够通过定位圈 11 与外围的调温 旋钮 10相连， 旋转旋钮 10， 就能够使旋转陶瓷片 7上的冷热水比例调节口 18对定陶瓷片 8上 的冷热水进水口 16 具有不同的连通面积， 进而调节水温。  The rotating ceramic piece 7 is located between the fixed ceramic piece 8 and the moving ceramic piece 6, and the three ceramic pieces are in close proximity. The rotating ceramic piece 7 has a groove at the edge, and the positioning ring 11 has a stud so that the rotating ceramic piece 7 can be connected to the peripheral temperature adjusting knob 10 through the positioning ring 11, and the knob 10 can be rotated to make the rotating ceramic piece 7 cold. The hot water proportional adjustment port 18 has a different communication area for the hot and cold water inlet 16 on the fixed ceramic sheet 8, thereby adjusting the water temperature.

The arc and the size are determined by the hot and cold water inlet 16 on the fixed ceramic piece, so that when the rotating ceramic piece is moved up and down, the hot and cold water ratio adjusting port 18 can be covered or connected regardless of the rotation of the rotating ceramic piece, and the moving ceramic piece can move up and down. It does not change its original position with the rotation of the rotating ceramic piece. Therefore, the water temperature can be easily adjusted during the bathing process, and once the temperature is adjusted once, the water valve can be opened several times to maintain the original suitable temperature.
图 8、 图 9、 图 10是本实用新型第二种方案的陶瓷片设计图。 如图所示， 与第一种方案相 异的是各陶瓷片上混合水出水口的形状和位置发生改变，图 8中的混合水出水口 17 ' 是根据冷 热水进水口 16' 的弧度和位置设计的半圆弧形口， 以及旋转陶瓷片上的混合水出水口 19' 也 是根据该半圆弧形口的弧度和位置设计 （旋转陶瓷片上的冷热水比例调节口 18 ' 与混合水出 水口 19' 以轴对称为优选）。图 10中的混合出水口 21 ' 与图 7中的相比，另一端的小扇形改为 大扇形 （其凹槽形状以轴对称为优选）。  8, 9, and 10 are design drawings of the ceramic sheet of the second embodiment of the present invention. As shown in the figure, the difference from the first scheme is that the shape and position of the mixed water outlet on each ceramic sheet are changed. The mixed water outlet 17' in Fig. 8 is based on the curvature of the hot and cold water inlet 16'. The semi-circular opening of the position design, and the mixed water outlet 19' on the rotating ceramic piece are also designed according to the curvature and position of the semi-circular opening (the ratio of the hot and cold water on the rotating ceramic plate 18' and the mixed water outlet 19 'The axis pair is called preferred.' The mixed water outlet 21' in Fig. 10 is changed to a large sector shape (the shape of the groove is preferably referred to as an axial pair) as compared with that in Fig. 7.
