Abstract
The invention relates to a device for mixing cold water and hot water to required temperature, in particular to a self-standing constant temperature water mixing valve with high precision for automatically mixing cold water and hot water to required temperature according to preset temperature. The self-standing constant temperature water mixing valve consists of a hot water inlet, a cold water inlet, a thermometer bulb protecting component, an adjusting handle, a restoring spring, and the like; the backs of the hot water inlet and the cold water inlet are provided with a pressure adjusting component respectively; the pressure at the water outlet of the hot water pressure adjusting component is controlled by the pressure at the cold water inlet, while the pressure at the water outlet of the cold water pressure adjusting component is controlled by the pressure at the hot water inlet, so that the cold water and the hot water flowing into the valve core have the same pressure, and when the water pressure increases or reduces, the pressure of the water flowing into the valve core increases or reduces synchronously under the action of the pressure adjusting component, thereby the pressures of the cold water and the hot water in the valve core are constantly same; because the water pressure of the hot water flowing into the valve core is controlled by the pressure at the cold water inlet, while the water pressure at the water inlet of the cold water is controlled by the pressure at the hot water inlet, the pressure difference of the cold water and the hot water is not limited, the water mixing valve can work in large pressure difference, but the temperature of the outflow water is not affected by the increase or reduction of the water pressure.
Description
Affiliated technical field
The present invention relates to a kind of device that cold water and hot water is mixed into needed temperature, especially can automatically cold water and hot water be mixed into a kind of high precision self-supporting thermostatic water mixing valve of needed temperature according to predefined temperature, belong to hot-water supply system's manufacturing field of equipment.
Background technique
At present, various hot-water supply systems are quite universal, the application of various hot-water supply system's equipment also is found everywhere, but, the hot water temperature that problem demanding prompt solution of ubiquity is supplied with when fluctuation takes place hydraulic pressure in present hot-water supply system also changes, can't the guarantee supply constant-temperature effluent of hot water descends the quality of hot water supply.In addition, if cold water has taken place suddenly in present hot-water supply system to open circuit, can't cut off the supply of hot water immediately, the hot water temperature of supply is raise, injure user's safety, in order to address the above problem, many constant-temperature water mixing valves have appearred on market at present, but all can't solve and cut off the long problem of time of hot water when the variation of the water-exit temperature that water pressure fluctuations brings and cold water interrupt suddenly, the invention provides a kind of a kind of high precision self-supporting thermostatic water mixing valve that hot water temperature that power supply just can guarantee to supply with does not also change that need not when fluctuation takes place hydraulic pressure, when the supply of unexpected interruption cold water, a kind of high precision self-supporting thermostatic water mixing valve that cuts off the supply of hot water immediately automatically.
Summary of the invention
The objective of the invention is: provide a kind of power supply that do not need according to predefined temperature cold water and hot water to be mixed into a kind of high precision self-supporting thermostatic water mixing valve that preestablishes temperature automatically, when the supply of unexpected interruption cold water, a kind of high precision self-supporting thermostatic water mixing valve that cuts off hot water supply immediately automatically.
Solving the technological scheme that its technical problem adopts is that a kind of high precision self-supporting thermostatic water mixing valve is by the hot water inlet; cold water inlet; thermometer bulb protection assembly; regulating handle; compositions such as Returnning spring; it is characterized in that: respectively increase a pressure regulation assembly at hot water water inlet and cold water water inlet back; the pressure of the water outlet of hot water pressure regulation assembly is by the pressure control of the water inlet of cold water; and the pressure of the water outlet of cold water pressure regulation assembly is by the pressure control of the water inlet of hot water; make the hot and cold water that enters into spool have identical pressure; when increasing or reduce, hydraulic pressure under the effect of pressure regulation assembly, make the hydraulic pressure that enters into spool simultaneously with increasing or reduce pressure like this; the pressure that has guaranteed the hot and cold water in spool is identical all the time, and the temperature of water outlet is not subjected to the influence that increases or reduce because of hydraulic pressure.
The working principle of pressure regulation assembly is that hot water Regulation Control joint connects the cold water water inlet, cold water Regulation Control joint connects the hot water water inlet, like this, the pressure of the epicoele of hot water pressure regulation barrier film is identical with cold water water inlet pressure, the pressure of the epicoele of cold water pressure regulation barrier film is identical with hot water water inlet pressure, when the pressure of cold water water inlet is higher than hot water mouth's pressure, because the pressure of hot water pressure regulation assembly water outlet is subjected to the control of the pressure of cold water water inlet, hot water pressure regulation assembly is all opened, the maximum that guarantees hot water is supplied with, simultaneously, because the pressure of cold water pressure regulation assembly water outlet is subjected to the control of the pressure of hot water water inlet, will make the discharge pressure of hot water pressure regulation assembly adjust in the heat hydraulic pressure identical, guarantee that the pressure of hot and cold water in mangetic core assembly is identical, because the hydraulic pressure that hot water enters into spool is the pressure control by the water inlet of cold water, and the hydraulic pressure of cold water water inlet is by the control of hot water water inlet, so just make that the pressure reduction of hot and cold water is unrestricted, this mixed water valve is operated under the great pressure reduction.
The invention has the beneficial effects as follows; owing to adopted the control of pressure regulation assembly; can guarantee that a kind of high precision self-supporting thermostatic water mixing valve can proper functioning under any pressure reduction of hot and cold water; and water-exit temperature is not subjected to the influence of water pressure fluctuations; guaranteed a kind of precision of high precision self-supporting thermostatic water mixing valve water-exit temperature; when unexpected generation cold water interrupted, hot water can cut off immediately, has protected user's safety.
