Description

Four-way cold pulse modulation water-mixing valve

The invention provides a kind of four-way cold pulse modulation water-mixing valve.

Mixed water valve has many patents, mainly contains the automatic water-mixing control valve and mixes water valve two big classes with machinery.The control valve aspect, foreign patent similar techniques EP 569437-B1, EP 708282-A1 and 93JP-189162, US5579992-A, Chinese patent is representative CN 87208673U, CN 2112735U, ZL 94112481.9, ZL 94229476.9, ZL 96225374.x and CN 96115082.3, and these patents respectively have advantage.The present invention does significant improvement to patent ZL 94112481.9 and CN 96115082.3.Though this binomial patent has formed approved product, its technical parameter is: at cold water hydraulic pressure is 0.05～0.3MPa, the hot water water temperature is that output water temperature can be regulated by continuously smooth between 35～70 ℃ under 40～70 ℃ the water and heat provision condition, yet still there is significant disadvantages in these patents and is not, it only considers to mix the 26S Proteasome Structure and Function of water valve itself, seldom take getting in touch and coordinating mutually of it and outer tube valve into account, give to install and use and bring many troubles and inconvenience, see from Mechanical Builds in addition to lack symmetrical beauty.The representative patent in mechanical valve aspect has ZL 95202263.x, and ZL 94220783.1, and ZL 9520923.1, and ZL 93235233.2, RU 2047033-C1 and US 5494077-A.Machinery mixes water valve and occupies an leading position in the application of cleaners and polishes, daily valve and field of water heaters.They are simple in structure, and are easy for installation, exquisite luxurious in moulding and appearance decoration, but the scientific and technological content of these products is not high, and it is not good enough to mix the water temperature adjusting performance.To mix water valve be by regulating the flow area of hot and cold water valve port (spool) respectively to machinery in essence, changes water temperature thereby regulate the different proportionings that enter the valve body hot and cold water.Three problems must appear thus: the one, because current also change with hydraulic pressure when flow area is constant, therefore machinery mixes the water temperature adjustment and must be subjected to influence of hydraulic pressure; The 2nd, owing to cold water is often different with pressure of hot water, theoretical and experience shows that all when the fluid of two kinds of different pressures was fed a container straight, both must be among a kind of unsettled transient equiliblium, is difficult to mix and not just out of the question temperature adjustment of mixing.Not only just having mixed up for the moment has interference slightly but also can become; The 3rd, the mixed water valve of machinery will rotate cold and hot two knobs usually and regulate water temperature, and this is not only inconvenient, and is easy to generate misoperation, particularly the elderly.

In view of the above, the target of this patent is that the design temperature adjustment function is good, handsome in appearance, connects simply mixed water valve easy to use.

The cooling pulse modulation principle that previous patent is provided effectively solves the mixed water temperature adjustment problem of hot and cold water under pressure imbalance and change conditions with better simply mechanism.This patent then will be done a kind of new structural design and make that the basic building block that mixes water valve and supporting valve pipe fitting are molten to be one, and with to show health bath apparatus connection form harmonious, one integrated mass.For this reason, the basic ideas of this patent are: consider from the function of mixing water valve and with outer pipeline bind mode, plan to mix water valve and be designed to four passages (cold water, hot water, water inlet, mixed water); From the angle of symmetrical beauty, above four water channels should be criss-crossing, and take twinned symplex structure being provided with of valve pipeline.This patent is named the bare bones that " four-way cold pulse modulation water-mixing valve " characterizes above-mentioned design just.
