Description

Balance valve with asymmetric structure

The present invention relates to a balancing valve, and more particularly to an innovative structural type designer that achieves the function of retaining cold water supply through the technical characteristics of the left and right asymmetric type.

According to the traditional double-temperature ceramic valve, the use of the traditional double-temperature ceramic valve is easy to cause the water temperature to be overheated and burned, and the cold and hot water pressure is unstable, and the water temperature is not easy to control. The double-temperature ceramic valve is internally combined with a modified structure of a hot and cold water balance valve (note: referred to as a balance valve in this case).

At present, there are quite a few pre-existing patents for ceramic valve products and related technologies with balance valves. However, there are still some problems and shortcomings that cannot be improved.

The conventional balance valve is composed of a fixed valve tube and a movable valve core. The fixed valve tube has a through hole at two ends, and the two sides of the fixed valve tube are respectively provided with a through hole for introducing cold and hot water. The two ends of the movable valve core are respectively formed with an inner groove, and the two inner grooves are separated by a partition, and the two inner grooves are also provided with a through-opening and a through-opening of the fixed valve tube; In this structure type, when the cold and hot water flows respectively pass through the two inner grooves of the movable valve core through the two sides of the fixed valve tube, the principle of the flow rate is fast, the pressure is slow, and the pressure is slow, and the water flow property is made. The movable spool will produce a lateral reciprocating migration movement along with the flow rate of the cold and hot water flow, thereby changing the communication cross-sectional area of the movable valve core and the fixed valve tube on both sides to achieve automatic balance of cold and hot water temperature. The function and purpose.

However, the conventional balance valve has found that the following problems still exist in the practical application experience: the traditional double-temperature ceramic valve integrates the balance valve structure and function, although the user completely pulls the faucet handle to the full cold water mode or is fully hot. In the water mode, the function of the full cold water and the full hot water is not affected, which is in terms of the function of switching the hot and cold water of the ceramic valve.

However, from the perspective of the hot and cold water supply end, in the mode where the dual temperature ceramic valve is switched to both cold and hot water supply, if the hot water line is unpredictable at this time (such as pipeline rupture, pipeline control) When the valve is closed, the pipe is blocked, etc., and the pressure loss is blocked, since the movable valve core of the balance valve will abut against the hot water side of the fixed valve pipe, the hot water flow path is blocked and closed. At this time, between the active valve core and the cold water side opening of the fixed valve core, the flow path is blocked due to being completely staggered from each other, that is, the conventional balancing valve blocks the pressure loss state in the hot water pipe. The cold water supply function will automatically block the loss, which will cause the faucet to use the function and convenience of the shortcomings and problems (Note: because the cold water mode is the most commonly used mode of the average person).

Therefore, in view of the problems existing in the use of the above-mentioned conventional balancing valve, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goal and direction of breakthrough.
