This is practical to relate to and a kind ofly can regulate the adjusting device that gas heater (hereinafter to be referred as water heater) is supplied with the hot water water temperature in the bathroom.

Water heater commonly used for the purpose of safety, require it must be installed on outside the bathroom, the bather wants to obtain the hot water of preference temperature when bathing, can only before entering the bathroom, mix up the air volume regulating valve on the water heater, enter the mode temperature adjustment of regulating with constant load by the cold water water yield that increases or reduce to enter water heater again behind the bathroom, water heater adds the function of tonic chord of hot water usually can not be given full play to, the bather can not obtain the maximum heat water yield that water heater can provide usually, when extraneous variation in water pressure is big during bathing, the bather can't regulate water temperature by regulating pondage, usually have to call out other people help to regulate water heater outside the bathroom air volume regulating valve, it is very inconvenient to use; When hydraulic pressure is not enough, or when summer, water temperature itself was too high, water heater can only flow out the too high hot water of a small amount of temperature and make the bather be difficult to bathing.In order in the bathroom, to regulate water temperature voluntarily by the bather, utility model patent " water temperature regulation device in the gas heater bathroom " (patent No. 93201440.2) adopts control to regulate water temperature to the mode of the hot water injection cold water water yield of water heater outflow, solved this problem, yet it need be regulated the aperture of three valves of three knob position changes and regulate water temperature, still some inconvenience during use.

At the problems referred to above, the purpose of this utility model is a kind of and supporting use of gas heater of design, can directly be installed in the bathroom, only can regulate the valve of water temperature continuously with a knob.

The utility model mainly is made up of valve component, knob, valve core and intermediate sleeve, be characterized in that valve component is a hollow cylinder, on four joint I, II, III, IV are arranged, link to each other with spray head with water source from the beginning, water heater cold water inlet, water heater hot-water outlet respectively; Intermediate sleeve connects firmly in the valve component inner chamber, has a horizontal tank A on its outer wall, two vertical tank B, H and three water window C, D, G that the height diverse location interlaces, and three tank A, B, H lead to three water window C, G, D respectively; The valve core bottom that connects firmly together with knob is the cup-shaped of a back-off, cup-shaped outer garden face and intermediate sleeve endoporus sliding fit, cup-shaped top has two window E, the F that the height diverse location interlaces, one exhausting hole L is arranged under the cup-shaped bead, and endoporus is that the knob sleeve of screwed hole is contained on the external screw thread face on valve component top.

Fig. 1 is front view schematic diagram of the present utility model (being the M-M revolved sectional view of Fig. 2).

Fig. 2 is the P-P cross-sectional schematic of Fig. 1.

Fig. 3 is that Fig. 1 is the outer garden face expansion schematic diagram of middle valve core (3).

Fig. 4 is that the endoporus of intermediate sleeve among Fig. 1 (4) launches schematic diagram.

Fig. 1-Fig. 4 is the schematic diagram of an embodiment of the utility model, in this embodiment, when four joint I, II of valve component (1), III, IV respectively with water source from the beginning, when the hot water outlet of water heater cold water inlet, water heater and spray head were connected, running water can flow into the cold water inlet of water heater all the time from joint I through the joint II of the horizontal tank A of intermediate sleeve (4).Open water heater, the knob (2) of outwarding winding, because itself and valve component (1) are thread connection, the valve core (3) that connects firmly together with knob (2) rises on while rotating, the circular bead surface of the bead circular bead surface of valve core (3) and intermediate sleeve (4) breaks away from and makes and form a toroidal cavity (we will be referred to as water annulus later on) between the two, simultaneously, the water window E of valve core (3) overlaps with water window C on the intermediate sleeve (4) gradually, form the cold water mouth of a river, by joint I stream come cold water pass intermediate sleeve by the cold water mouth of a river and valve core enters the valve core inner chamber, exhausting hole L on valve core (3) flows into water annulus, water window G on intermediate sleeve (4) and vertical tank B and joint IV flow to spray head, and what flowed out this moment is cold water.Increasing along with knob (2) anglec of rotation, the water window F of valve core (3) overlaps with the water window D of intermediate sleeve (4) gradually, form the hot water mouth of a river of strengthening gradually, the area of the water window E of valve core this moment (3) has contained the area of the water window C of intermediate sleeve (4) fully; The aperture at the cold water mouth of a river (actual is the area of two water window intersection) will remain unchanged, the cold water water yield that flows into valve core (3) inner chamber keeps certain value, to increase and pass the hot water water yield that intermediate sleeve (4) and valve core (3) enter the valve core inner chamber through the hot water mouth of a river of strengthening gradually, via through holes L, water annulus, water window G and vertical tank B flow to the temperature adjustment hot water temperature that joint IV enters spray head and will slowly rise after valve core inner chamber and cold water mix.Continue rotation knob (2), water window E on the valve core (3) no longer can contain the water window C on the intermediate sleeve (4), the hot water mouth of a river aperture that both intersection form remains unchanged, the hot water water yield that flows into valve core (3) inner chamber is constant and the cold water water yield reduces, and makes the temperature adjustment hot water temperature of flowing out from spray head rise rapidly.When knob (2) rotates to certain angle, the aperture at the cold water mouth of a river will be 0, and this moment, the aperture at the hot water mouth of a river constantly reduced, and was equivalent to turn down when water heater works independently the water yield, and water temperature will sharply rise with the rotation of knob (2).

Reverse rotation knob (2), water temperature then from high temperature to low temperature, becomes cold water from hot water, and when being closed state on the flange circular bead surface of valve core (3) is pressed on the circular bead surface of intermediate sleeve (4), water annulus is closed, and valve cuts out.

Like this, only rotate (2) knobs of knob, just can realize the continuous adjusting of water temperature.

Regulate warm mode with existing other water heaters and compare, the utlity model has following characteristics:

1. can be installed in the bathroom by the bather and realize water temperature with a knob Regulation and control, safe and convenient to use.

2. adopt elongated slot to overlap gradually or throw off, this becomes that are constant the cold and hot mouth of a river, and that becomes this constant mode and regulates the ratio that enters the hot and cold water water yield that valve core (3) inner chamber mixes, and water temperature changes mild, and knob rotates same angle water temperature and changes for a short time, and thermoregulation effect is good.

3. make the water heater of adapted can bring into play the function of tonic chord that adds hot water to greatest extent, make the bather obtain the more temperature adjustment hot water of big yield, bathing is more comfortable.Even the hydraulic pressure deficiency, when general water heater only can be supplied with the excessive temperature hot water that is unsuitable for bathing, this valve of adapted still can provide the bath hot water of preference temperature.

4. nearly all water heater all exists needs the of short duration situation of stopping using hot water in the bathing process, when opening tap once more, because hot water stays for some time in water heater, temperature can be very high, so can not contact human body when opening hot water at once, otherwise cause scald easily, use this valve then can avoid the appearance of this problem, because water temperature raises gradually from low temperature forever when outwarding winding this valve.
