Abstract

The utility model discloses a vapor-water mixing valve which can directly mix the vapor and the cold water in the valve., and the hot water is obtained. The valve mechanism of a diaphragm push rod which is controlled by the cold water pressure is arranged on the vapor path of a valve body, the vapor and the cold water are directly mixed in a vapor-water mixing chamber in the valve according to the determinate proportion, and the hot water with moderate temperature is obtained. The utility model has the advantages of rapid heat exchanging process, small heat loss, small occupation area, and low noise.

Description

The carbonated drink mixing valve

The utility model belongs to valve and makes the field.

At present, people are when adopting steam to make it to become hot water as thermal source heating cold water, and general the employing put into a large water tank with cold water, steam pipe realized by the method in the water that there are some shortcomings in this practice again, and noise was big when (1) steam mixed; (2) the heat-exchanging water tank volume is big, and the occupation of land space is big; (3) vapour road and water route are independent separately, and the overheated scald of water outlet water user accident easily takes place.

The purpose of this utility model is a kind of carbonated drink mixing valve of design, makes it to overcome the above shortcoming of prior art.

The purpose of this utility model is to realize by following means.

Steam channel, cold water channel, carbonated drink hybrid chamber are set on the valve body and are attached thereto logical hot water outlet, and on the air inlet pipeline between steam channel and the carbonated drink hybrid chamber, the diaphragm rod valve mechanism that is subjected to cold water pressure control is set.Two branch roads of press mold passage that cold water channel has water channel and communicates with the press mold water cavity are equipped with water regulating valve on the water channel.

After adopting structure as above, steam enters the interior steam hybrid chamber of valve with cold water and directly mixes the back by hot water outlet discharge hot water, only need heat-exchanging water tank be set again, has reduced heat and has scattered and disappeared, and has saved the water tank space, has saved the energy, has reduced noise pollution.Simultaneously, owing to adopt the diaphragm rod valve mechanism that is subjected to cold water pressure control is set on gas circuit, the air inflow water of catching a cold flows into the control of pressure, does not also have gas when anhydrous, and gas became big when water was big, and water temperature is constant relatively, the steam casualty accident can not take place.

Description of drawings is as follows:

Fig. 1 is A-A cutaway view (pass closed state) of the utility model embodiment.

Fig. 2 is A-A cutaway view (unlatching attitude) of the utility model embodiment.

Fig. 3 is B-B cutaway view of the utility model embodiment.

In Fig. 1, valve body is provided with steam channel, cold water channel, 1 is the steam inlet, 2 is cold water inlet, carbonated drink hybrid chamber 3 and be attached thereto logical hot water outlet 4, cold water channel has water channel and two branch roads of press mold passage, advance a cold water part and flow into water cavities 7 by water supply port 6 by control valve 5 controls, and inject carbonated drink hybrid chambers 3 by hole 8 and ring-type crack 9.Steam enters steam channel by vapour inlet, its direction of motion as shown by arrows, in the obstruct that in carbonated drink hybrid chamber flow process, is subjected to air valve 10, air valve 10 is controlled by the diaphragm transfer bar mechanism of cold water pressure control, the part of cold water enters press mold water cavity 12 by the blasthole 11 of mould path, moved up by the effect diaphragm 13 of hydraulic pressure, the push rod 18 that connects firmly as shown in Figure 2 on diaphragm 13 also moves upward thereupon, air valve 10 is backed down, thereby make steam pass through air gap 14, carbonated drink hybrid chamber 3 is injected in pore 15 and ring-type crack 9, carbonated drink is fully discharged by hot water outlet 4 after the mixing heat exchange in hybrid chamber, hot water outlet the position is set as shown in Figure 3.

The water temperature of hot water outlet can be controlled by two aspects, controls by control valve 5 control outputs on the one hand; Can control by the position that adjusting is arranged on the cone governor bar 16 in the push rod 18 elastic recovery mechanisms on the other hand, awl bar 16 is transferred lowly more, and conehead 17 positions are low more, are subjected to its spacing influence, and the air gap of air valve 10 is more little, otherwise big more.The regulative mode and the structure of awl bar are diversified, just have different length at Fig. 1 with awl bar on Fig. 2.

Because special construction of the present utility model, cut-offfing of steam depends on that fully the cold water that has or not suitable pressure flows into, anhydrous no gas, and the big flood atmosphere, the danger of both having avoided steam to scald makes institute's heat supply water constant in certain temperature range again.
