Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of self-control thermostatic water-mixing valve.
Background technique
Along with the raising of social progress and living standards of the people, people constantly pursue comfortable living conditions, and wherein, the supply of hot water has become one of indispensable demand.Consider that from angle safe in utilization the heat supply of water-storing type is faced with two big predicaments: on the one hand, water temperature is in to cause easily under the relatively mild state has a liking for the lung legionaires' disease.Past 30 in the period of, the legionaires' disease that causes because of wet environments such as air-conditioning system, water storage systems all over the world concentrates morbidity to happen occasionally, research shows, water temperature is risen to more than 60 ℃ just can kill Legionella.But on the other hand, the hot water more than 60 ℃ is directly delivered to the rats after severe scald burn that user side may cause the user.Discover through various countries; The approach of head it off is: with the water reservoir water temperature in heating system heating and remain on more than 60 ℃; And with constant-temperature water mixing valve the hot water temperature of user side is reduced to the suitable temperature of setting before use, can avoid scalding the breeding of also stopping Legionella simultaneously.The use of constant-temperature water mixing valve; With the hot water supply water temperature be controlled at 48 ℃+below 5 ℃; This is not only and considers that the user can not scalded, and is farthest to reduce the thermal loss of hot water in line transportation, the waste of avoiding the unnecessary high-temperature-hot-water in user waterexit end to cause; The effect of safety control and energy saving be can play, good social benefit and economic benefit created.
Yet still there is the drawback in the various designs in existing constant-temperature water mixing valve, and for example: the installation between valve body and the adapter is cumbersome; Temp-controlling element is insensitive; Mix when water valve is inner to produce pressure reduction the adverse current phenomenon takes place easily, cause thermal source to run off; Impurity in the water, dirt get into easily and mix in the water valve, cause mixing the water valve inner chamber and stop up, and influence flow etc.These drawbacks cause the temperature control effect of constant-temperature water mixing valve not ideal enough.
Summary of the invention
