Abstract
The utility model relates to a gas flow control valve for a gas water heater, wherein, a channel communicated with the external gas is arranged in the valve body. The utility model is characterized in that a plurality of air chambers communicated with each other are arranged in the valve body; each air chamber is provided with a nozzle, wherein, only one air chamber is communicated with the gas channel, and a valve stem is arranged in the air chamber; the valve stem is provided with a spring whose one end in the air chamber is connected with a sealing device which can isolate the air chambers from each other. The utility model has the advantages of lowering CO content in the smoke, high thermal efficiency, large water temperature regulating range, etc.
Description
The utility model relates to a kind of gas heater tolerance control valve.
Traditional gas instantaneous water heater is in different regions, when having occurred to some extent using summer water outlet too hot, and when using winter, the phenomenon that water temperature is on the low side, if will obtain bigger thermoregulation range, keep the good combustion situation again, traditional tolerance governor motion is difficult to realize.
The purpose of this utility model provides a kind of at the gas heater tolerance control valve that is not changing change leaving water temperature under the situation that enters burner gas flow rate, combustion gas and air proportioning.
In order to achieve the above object, the utility model is to realize like this, be provided with the path that communicates with extraneous combustion gas in its valve body, it is characterized in that: in valve body, be provided with a plurality of air chambers that communicate mutually, each air chamber is provided with nozzle, wherein has only an air chamber to communicate with fuel gas path, and be provided with a valve rod in this air chamber, be provided with spring on valve rod, its end in air chamber is provided with the sealing device that can isolate each air chamber.In valve body, be provided with two air chambers.The interface of each air chamber is the conical surface or plane.The sealing device of isolating each air chamber is sealing ring or seal valve piece.
The utility model compared with prior art has following advantage:
1, the thermal efficiency increases, and CO content in smoke reduces significantly;
2, gas flow rate remains on optimum state, can effectively prevent tempering, improves water heater service life, and keeps safe in utilization;
3, can increase the adjustable extent of leaving water temperature greatly, avoid the leaving water temperature height in summer that the temperature difference is caused because of the regional temperature difference, season, the low problem of leaving water temperature in winter makes the user use in different seasons from different places, can both obtain comfortable, satisfied leaving water temperature.
The structural representation of Fig. 1 the utility model embodiment one opening;
The structural representation of Fig. 2 the utility model embodiment one closed condition;
The structural representation of Fig. 3 the utility model embodiment two openings;
The structural representation of Fig. 4 the utility model embodiment two closed conditions.
Below in conjunction with drawings and Examples the utility model is done further detailed description:
Embodiment one
As shown in Figure 1, 2, be provided with the path (3) that communicates with extraneous combustion gas in its valve body (2), in valve body (2), be provided with two air chambers that communicate mutually (9), the interface of 2 air chambers (9) is the conical surface (6 (A)), be equipped with nozzle (4) on the 2 air chambers (9), wherein have only an air chamber (9) to communicate with fuel gas path (3), and in this air chamber (9), be provided with a valve rod (8), on valve rod (8), be provided with spring (7), its end in air chamber (9) is equipped with the sealing ring (5 (A)) that can isolate 2 air chambers (9), and the other end is provided with summer in winter selection knob (1).During use, when winter or the higher leaving water temperature of needs, rotating the summer in winter selects knob (1) to pull out valve rod (8), drive sealing ring (5 (A)) and leave sealing surface (6 (A)), combustion gas is injected all burners via nozzle (4), it is burnt simultaneously, and the cold water thermal-arrest hydrophone of flowing through carries out heat exchange, can obtain the hot water of higher temperature.When summer or when needing low leaving water temperature, rotating the summer in winter selects knob (1) to discharge valve rod, valve rod (8) is under the effect of spring (7) power, promote sealing ring (5 (A)) plug for seal face (6 (A)), combustion gas is only penetrated via nozzle (4) and is only injected in two rows (or a row) burner, makes its normal combustion.And all the other burners quit work, and the cold water heat collector of flowing through exchanges the hot water that can obtain lower temperature.
Embodiment two
Shown in Fig. 3,4, be provided with the path (3) that communicates with extraneous combustion gas in its valve body (2), in valve body (2), be provided with two air chambers that communicate mutually (9), the interface of 2 air chambers (9) is plane (6 (B)), be equipped with nozzle (4) on the 2 air chambers (9), wherein have only an air chamber (9) to communicate with fuel gas path (3), and in this air chamber (9), be provided with a valve rod (8), on valve rod (8), be provided with spring (7), its end in air chamber (9) is equipped with the seal valve piece (5 (B)) that can isolate 2 air chambers (9), and the other end is provided with summer in winter selection knob (1).The use step is same as described above.
Claims (4)
1, a kind of gas heater tolerance control valve, be provided with the path that communicates with extraneous combustion gas in its valve body, it is characterized in that: in valve body (2), be provided with a plurality of air chambers that communicate mutually (9), each air chamber (9) is provided with nozzle (4), wherein have only an air chamber (9) to communicate with fuel gas path (3), and be provided with a valve rod (8) in this air chamber (9), be provided with spring (7) on valve rod (8), its end in air chamber (9) is provided with the sealing device that can isolate each air chamber.
2, gas heater tolerance control valve according to claim 1 is characterized in that: be provided with two air chambers (9) in valve body.
3, gas heater tolerance control valve according to claim 1 and 2 is characterized in that: the interface of each air chamber (9) is the conical surface (6 (A)) or plane (6 (B)).
4, gas heater tolerance control valve according to claim 1 is characterized in that: the sealing device of isolating each air chamber is sealing ring (5 (A)) or seal valve piece (5 (B)).
