The interfeedback automatic adjusting valve is especially suitable for automatically controlling the water temperature of cold and hot water. The interfeedback automatic adjusting valve is characterized in that a hollow valve plug is arranged in a valve body, which forms two pressure chambers which are respectively communicated with one pressure feedback tube; the inlet of the cold and the hot water of the valve body is directly communicated with the mixing chamber with the hollow valve plug; after water is mixed, the water flows out from the water outlet of the mixing chamber. The utility model has the advantages of simple structure, easy installation, and convenient operation; the interfeedback automatic adjusting valve ensures that the water temperature of shower water can not generate abrupt change, and enables users to feel comfort and safety. The utility model can be installed in various boiler rooms and shower rooms.
Description
A kind of interfeedback type hot and cold water mixed pressure automatic regulating valve, it relates to fluid transmission and control technique field, particularly is applicable to the automatic control of hot and cold water water temperature.
Now general collective public shower chamber or Household bathroom all adopt two independent gate valves to control hot and cold water respectively and enter shower nozzle.This regulating method can not be eliminated the water temperature that produces because of the cold and hot water source variation in pressure caused adverse consequences of suddenling change.Only go out cold water as shower nozzle, bath person can feel under the weather; Shower nozzle only goes out hot water then can scald bath person." the hot and cold water mixing modulating valve " that China designs in disclosed No. 85108280 patents " Gazette of Patent for Invention " on August 5th, 1987, it is by the spheroid valve plug, three passages and the valve rod that are compiled in the centre of sphere are formed, utilize valve rod may command valve plug to change the flow direction of water in three passages, reach the purpose of the proportions of ingredients of control hot and cold water.This mixing valve for cold and hot water has only solved and has utilized a valve handle to regulate the problem of water temperature, and does not solve the problem of the hot and cold water proportions of ingredients variation that is produced when hot and cold water water source temperature and pressure changes.
The purpose of this utility model is will provide a kind of can be used for collective's shower room, Household bathroom or boiler room, and can regulate the pressure that hot and cold water enters the hot and cold water mixing chamber automatically, make it be tending towards optimum value, make the and then automatic regulating valve of sudden change of water-exit temperature because of the pressure jump of cold and hot water source in the hope of not taking place.It can guarantee the shower water temperature, but using water wisely again.
The purpose of this utility model is achieved in that
A kind of interfeedback type hot and cold water mixed pressure automatic regulating valve is characterized in that being equipped with in the valve body (14) valve plug (6) of a hollow valve body active chamber being divided into a cold water pressure chamber (5) and a heat hydraulic pressure chamber (8); Cold water pressure chamber feedback pipe (12) is fed cold water pressure chamber (5), the heat hydraulic pressure is fed back pipe (13) feed heat hydraulic pressure chamber (8); The cold water inlet (11) of valve body (14) and water inlet of hot water (1) directly feed the middle vacancy of valve plug (16), also are in the hot and cold water mixing chamber (4); On valve body (14) and valve plug (16), establish common mixed hot water water outlet (6).In two pressure chambers of valve body (14), be provided with location collar (7), on two feedback pipes temperature control cock (12) (10) be installed.Its working principle is: when hot water or cold water's hydraulic pressure changes, the pressure of its variation is transferred to the hot water or cold water pressure chamber by the pressure feedback pipe, valve plug (16) produces mobile because of the different pressure that is subjected to the hot water or cold water pressure chamber, thereby open or partly close hot water or cold water's water intake, the ratio that makes the hot water or cold water enter hot and cold water mixing chamber (4) changes, and the water-exit temperature that assurance blends the mouth of a river (6) is constant.When if the water temperature at hot and cold water source is undergone mutation, then can adjust temperature control cock (2) (10), can change the pressure of hot water or cold water pressure chamber equally, make valve plug (16) produce and move that the water outlet (6) that reaches maintenance mixing chamber (4) is located the constant purpose of water-exit temperature.(9) be cooling water inlet on the hot and cold water mixing chamber (4).
Accompanying drawing 1 is a structure cut-away view of the present utility model;
Accompanying drawing 2 is a partial cutaway diagrammatic sketch of the present utility model;
Further specify below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing.
(14) be valve body of the present utility model, (13) feed back pipe for the heat hydraulic pressure on the valve body (14), (12) be cold water pressure feedback pipe on the valve body, (16) be the cylinder type valve plug of hollow, (15) be mixing water water outlet on the valve body, (11) be cold water inlet on the valve body, (1) is water inlet of hot water on the valve body, (7) be the location collar, it can limit the displacement range of valve plug (16), and (10) feed back temperature control cock on the pipe for the heat hydraulic pressure, (2) be the temperature control cock on the cold water pressure feedback pipe, (4) be the interior hot and cold water mixing chamber of valve plug (16), the mixed water exports of (6) mixing chamber, (3) are the hot water inlet of mixing chamber.(9) be cold water inlet on the hot and cold water mixing chamber (4).
When pressure of hot water diminishes suddenly, feed back the effect of pipe (13) by the heat hydraulic pressure, the pressure of heat hydraulic pressure chamber (8) diminishes thereupon, valve plug (16) moves right under cold water pressure chamber (5) bigger pressure effect, the cold water inlet (11) of valve body (14) is turned down, reduce the flow that cold water enters mixing chamber (4), make the water-exit temperature that blends the mouth of a river (6) remain unchanged.When cold water pressure diminishes suddenly, its pressure imports cold water pressure chamber (5) into by cold water pressure feedback pipe (12), the pressure of cold water pressure chamber (5) reduces, valve plug (16) is moved to the left under the effect of heat hydraulic pressure chamber (8), water inlet of hot water (1) is closed, guarantee that the mixing water water-exit temperature is constant.If cold water and hot water source's temperature when changing, then need to regulate with the temperature control cock.When the hot water temperature raises, can regulate cold water temperature control cock (2) makes the pressure of cold water pressure chamber (5) less than the pressure of heat hydraulic pressure chamber (8), and valve plug (16) moves to left, and turns down water inlet of hot water (1), keeps mixing chamber (4) water-exit temperature constant.When the hot water temperature reduces, regulate hot water temperature control cock (10), make the pressure of heat hydraulic pressure chamber (8) less than the pressure of cold water pressure chamber (5), valve plug (16) moves to right, turn down cold water inlet (11), reduce the flow that cold water enters mixing chamber (4), the water outlet of mixing chamber (4) is remained unchanged.
If valve plug (16) is made two independent cavitys and corresponding two outlets, valve body (14) is also made corresponding two outlets, just become interfeedback type two road four-way automatic regulating valves.By that analogy, can also make three the tunnel six and lead to,, select for use for multiple industry until the logical multi-path interfeedback type automatic regulating valve of N road 2N.
The utility model has solved the problem that produces because of the shower water pressure jump, makes the shower water water temperature can remain on the water temperature of first adjusting, makes bath person feel comfortable and safe.The utility model is simple in structure, and is easy to operate, connects easily with various boilers and shower water pipe.But and using water wisely.The utility model can generally use in various boiler rooms and collective's shower room.
