Abstract
The utility model relates to an automatic valve for constant temperature mixing cool and hot water, comprising a cold water port, a hot water port, and a warm water port. After the cold and the hot water is mixed in a mixing cavity, warm water flows out via the warm water port. A long and thin temperature sensing tube whose one end generates expansion following the variation of temperature is arranged between the mixing cavity and the warm water port. The expansion quantity of the temperature sensing tube are used for controlling the opening quantity of a cold water valve, which enables the cold water and the hot water to enter the mixing cavity at a definite proportional flow quantity, and realizes the automatic constant temperature control of water outlet temperature. The automatic valve for constant temperature mixing cool and hot water is used in a hot-water conduit, which has the advantages of simple structure, safety, convenience, etc.
Description
The utility model is about being made the expansion that is sealed in the temperature sensing liquid in the elongated pipe control the cold water inlet by water temperature, realizing the valve of outlet port water temperature stability, is the model utility of plumbing pipe with hot water or cold water's automatic constant-temperature mixing valve.
Always the acquisition of warm water all is made up of water valve and cold valves in the hot-water heating pipeline, regulates two handles that water temperature and flow need be regulated hot and cold water valve respectively, and it is not too convenient to use, when especially the hot water temperature is higher, regulate not really safe, the easier scald of old children.
The purpose of this utility model is to be applicable to old children and only to regulate flow, hot water or cold water's mixing valve of water outlet automatic constant-temperature with a water valve in order to provide a kind of.
Model utility is achieved in that mixing chamber, the elongated pipe that is sealed with temperature sensing liquid of warm water mouth arrangement between hot water or cold water's import and warm water mouth, and the end that the breathing of liquid in pipe can drive pipe elongates or shortens.When water valve is opened, the temperature-sensitive pipe of hot water in mixing chamber flows to warm saliva, the temperature-sensitive liquid in pipe expands rapidly, its expansive force backs down cold valves, and cold water promptly enters mixing chamber, after the hot water or cold water mixes, make water temperature reduction in the mixing chamber, the temperature-sensitive pipe just is contracted to an equilibrium position, causes cold water entering mixing chamber with the proportional flow of hot water, thereby guarantees that water-exit temperature is stabilized in predefined temperature.Setting temperature can be realized by the spacing increase and decrease liquid that changes temperature-sensitive pipe elongation end and cold water valve core.
The starting point of the present utility model provides the warm water of constant temperature, is convenient to take, thus saved adjustment process when taking warm water, can energy-saving and water-saving.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional drawing according to the hot water or cold water's automatic constant-temperature mixing valve that the utility model proposes.
Describe in detail according to specific structural details and the working condition that the utility model proposes below in conjunction with Fig. 1.
This valve comprises a main valve body (1), and a cold water outlet (2) is arranged on the main valve body, and cold water constitutes cold valves by the step (4) on spool (3) and the main valve body (1) and dams.Open water valve (not drawing among the figure), hot water flows into mixing chamber (6) the temperature-sensitive pipe (7) of flowing through from hot water mouth (5), the material of temperature-sensitive pipe is preferably selected the copper of good heat conductivity for use, liquid (8) is expanded rapidly, and screw (9) and packing ring (10) are used for sealing or the liquid (8) of increase and decrease temperature-sensitive pipe when setting thermostat temperature before installation.Step (11) on the main valve body (1) and top plug (12) are to extend along arrow (14) direction when stoping bellows (13) elongation that is welded into one with temperature-sensitive pipe (7), when the mean temperature of hot water is lower than setting temperature slightly, liquid (8) in the temperature-sensitive pipe (7) expands and makes bellows (13) back down cold valves by the expansive force of liquid (8), the colored groove (15) of cold water this moment on top plug (12), colored groove (16) on the spool (3) enters mixing chamber (6) to be mixed with hot water, water temperature in the mixing chamber (6) is descended, temperature-sensitive pipe (7) temperature-sensitive makes liquid (8) contraction rapidly in it, the spring (18) that bellows (13) and spool (3) are being pushed up mutually by plug screw with holes (17), and effect lower edge arrow (19) direction of cold water pressure moves, and can guarantee that warm water temperature is the regime flow that setting temperature flows to warm water mouth (20) thereby the flow of cold water is reduced to.If necessary, also can before installation, change spool (3) and come setting temperature with the spacing of bellows (13) surface of contact.
Claims (5)
1, a kind of hot water or cold water's automatic constant-temperature mixing valve of being made up of main valve spare, spool, temperature-sensitive pipe, spring, plug screw is characterized in that the temperature-sensitive pipe is placed in the mixing chamber warm water mouth between hot water or cold water's import and the warm water mouth.
2, the described hot water or cold water's automatic constant-temperature of claim 1 mixing valve is characterized in that the temperature-sensitive pipe is elongated.
3, claim 1,2 described hot water or cold water's automatic constant-temperature mixing valves is characterized in that being sealed with temperature sensing liquid in the temperature-sensitive pipe.
4, the described hot water or cold water's automatic constant-temperature of claim 3 mixing valve is characterized in that the flexible end of temperature-sensitive pipe is welded with bellows.
5, claim 3,4 described hot water or cold water's automatic constant-temperature mixing valves, the other end that it is characterized in that the temperature-sensitive pipe are to be used for sealing or the screw and the packing ring of increase and decrease temperature-sensitive pipe liquid when setting thermostat temperature before installation.
