Description

In the boiling water water fountain three flows to the sealing control valve

The utility model relates to a kind of control valve, and three in particularly a kind of boiling water water fountain flows to the sealing control valve.

The kind of present boiling water water appliance is more, and the electric water-heating cup or the water bottle of small capacity arranged, and they are the disposable water that adds, then heating.And another kind is the heating water boiler that uses for subsection, and it also adopts electric heating, and it is exactly that capacity is big with first kind difference, also lacks the automatic alimentation of cold water, that is, will drink after boiled and just can reburn second barrel.The third is bigger slightly vertical drinking machine, it disposes hot and cold tube, being not suitable for present office space but its volume is big uses, in addition, this unreasonable structure with sealing valve of the drinking machine of adding the cold water effect, when opening hot water, cold water can be isolated bad to the hot-water line seepage because of sealing, otherwise, when adding cold water, hot water also can be in cooling tube seepage flow, not only influence heats, and, the worry of the cold unboiled water that can drink not open, for addressing this problem, two groups of sealing valves generally will be set, not really convenient in the use operation.And at present because of the needs of office space sophistication, miniaturization, lacks and a kind ofly have cold water and store up and add function and small-sized boiling water water fountain, and the sealing control valve of this water fountain should possess heat supply water, add cold water injection, and seepage flow mutually not between cool and hot water pipe.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of prior art, both can do the hot water control valve and used and provide a kind of, and can do that cold water control valve uses, sealed to each other again and do not have three in the convenient and practical boiling water water fountain of mutual seepage flow and flow to the sealing control valve.

The purpose of this utility model is to realize by following technological scheme:

Be placed on a fixed cover in a hollow valve seat interpolation, activity has inserted one and has adjusted rotating shaft in the hollow fixed cover, the adjustment rotating shaft is not held and is provided with positioning screw cap, valve seat is circumferentially offered and is extended with and be cold, the adapter that the warm water water storage bag links to each other, valve seat extends axially an adapter that links to each other with the hot water water storage bag, fixed cover circumferentially offers two and takes over the osculum of corresponding perforation with cold warm water, axial side of fixed cover and hot water are taken over and are connected, offer separately cold of two mutually wrong 180 degree in the adjustment rotating shaft of hollow, the warm water water inlet, cold warm water water inlet can be by circumferential with the fixed cover respectively osculum conducting of the rotation of rotating shaft, and padding has the pad with isolating seal between each water channel between fixed cover and valve seat endoporus.

Therefore: remarkable result of the present utility model is:

1st, adjust rotating shaft in different positions by singlehanded the rotation, can reach water inlet in the rotating shaft and the cold warm water tube purpose of conducting respectively, can make cold water or warm water flow into the rotating shaft endoporus by cold warm water water storage bag respectively, and inject hot water liner through hot-water line and go heating, thereby, have the threeway effect of multi-purpose valve, make water fountain more convenient to use, structure is simpler.

2nd, owing to be arranged with the pad that hot and cold warm water can be taken over parting seal at fixed cover and valve base chamber, thereby, can prevent cold water enter in the warm water that can drink immediately and the hot water when heating in, have the wholesomeness of drinking.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing:

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.

Fig. 2 is that Fig. 1 adjusts the A of rotating shaft to partial enlarged view.

Fig. 3 is the sectional drawing after the utility model assembling.
