Hot and cold water control mixing valve

The invention relates to a "cold and hot water control mixing valve", in particular to balance the water pressure of the cold and hot water in the faucet to avoid a sudden drop in the amount of water, that is, the user is burnt or cold.

According to the current common hybrid faucet, it is generally limited to the design of the cold and hot water mixing device. If the water pressure abnormality changes (such as when the same house or multiple people on the same floor are used at the same time), it is impossible to actively regulate the pressure. The water temperature is prone to sudden cooling and rapid heating; especially in winter, if the hot water pressure suddenly becomes smaller, the flow rate will be sharply reduced, and the water temperature of the mixed faucet will be lowered, and then continue to be used. That is, it is easy to cause a cold. On the contrary, if the cold water pressure suddenly becomes smaller, the water temperature will suddenly rise, and there is a danger that the user will be burnt.

In addition, in order to control the water temperature at the same time, the water inlet ratio between the cold water end and the hot water end must be controlled first. Therefore, as shown in Fig. 9, a conventional water temperature control valve is mainly disposed in the valve body (40). There is a balancing valve (50), and the balancing valve (50) is provided with a circulation hole (51) (51') to communicate with the cold and hot water ends (41) (42), respectively, and two of the balancing valves (50). The end is connected with a cold and hot water flow channel (43) (44), and the balance valve (50) is additionally provided with a pressure regulating column (52), and the pressure regulating column (52) is matched with the flow hole (51) (51) ') An orifice (521) (521') is opened to allow cold and hot water to flow from the cold and hot water ends (41) (42) through the flow holes (51) (51') and the orifice (521). (521') is further flowed out from the cold and hot water flow passages (43) (44). When the water pressure at both ends is different, the pressure regulating column (52) is pushed by the water pressure to offset the lower end of the water pressure, thereby achieving The effect of controlling the water temperature, however, it is not difficult to find out the above structure. When the pressure regulating column (52) is offset, the pressure regulating column (52) will block the cold and hot water flow passages at the low pressure end (43) (44) ), so that the flow rate of the water is reduced sharply, and the water pressure is unstable, so that the effect of the actual action is reduced.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

Conventional hybrid faucets are generally limited to the design of cold and hot water mixing devices. For changes in water pressure anomalies, it is impossible to actively regulate the pressure, so that the water temperature is prone to sudden cooling and sudden heating, and in order to simultaneously control the water. Temperature, the system must be equipped with a balancing valve in the faucet, and the pressure regulating column of the balancing valve will block the cold and hot water flow channels when the offset column is offset, so that the flow of cold and hot water is sharply reduced, that is, the water pressure is unstable. In the case, the effect of the actual effect is lowered.

Continued from Figure 7 and Figure 8 with the view shown in Figure 2. If one end of the water supply is not normal during use, for example, if the hot water flow suddenly becomes small or stops abnormally, the balance valve (30) will function immediately. When the water flow at the hot water end becomes smaller or the water is cut off, the water pressure at the end will be suddenly reduced or disappeared, and the cold water end will have a large water pressure to apply force to the balance wall of the pressure regulating member (32) ( At 322), the pressure regulating member (32) is pushed in the direction of abnormal flow, so that the flow path of the water regulating port (321) and the annular hole (311) of the pressure regulating member (32) becomes smaller, thereby making the cold water The flow rate at the end is reduced to achieve the purpose of stabilizing the water temperature, and when the hot water returns to the normal flow rate, the pressure regulating member (32) is pushed back by the increase of the hot water pressure, so that the balance valve (30) can be subjected to The role of cold and hot water pressure balance, while maintaining the intermediate position, can maintain the water temperature in a fixed state of normal water supply; conversely, if the cold water flow suddenly becomes smaller or abnormally stops circulating, the balance valve of the balance valve (30) (32) will also be pushed in the reverse direction, which will prevent the user from being burnt. Further, the pressure regulating member (32) is opened at the voltage regulating section (323) at both ends. The voltage stabilizing hole (324) maintains the flow area of the side flow channel (25) (25') by the voltage stabilizing hole (324) when the pressure regulating member (32) is affected by the pressure difference and is biased toward the low voltage end. It can prevent the flow of the side flow passage (25) (25') from being suddenly reduced and the water pressure change too much, so as to achieve the effect of the voltage regulation.

By the structure of the above specific embodiment, the following benefits can be obtained: (1) The balance valve (30) can actively adjust the flow rate of the cold and hot water ends to avoid the water temperature being lowered due to the sudden decrease of the water pressure at one end. The phenomenon of cold and hot, so it will be relatively comfortable to use, and there will be no scald or cold flu during use; (2) when the pressure regulating member (32) is affected by the pressure difference and is biased toward the low pressure end When slipping, the flow area of the side flow passage (25) (25') is maintained by the pressure regulating hole (324), that is, the flow rate of the side flow passage (25) (25') is prevented from being suddenly reduced, and the water pressure is excessively changed.俾 to achieve the effect of the voltage regulator.
