Abstract
The utility model provides a fuel gas proportion valve, comprising a proportion valve body, an air inlet chamber, an air outlet chamber, a septum, and a valve. The air inlet chamber consists of the proportion valve body, the septum and the valve; the air outlet chamber is arranged behind the air inlet chamber and consists of the proportion valve body and the valve; one side of the septum is connected with the air inlet chamber; the valve is arranged between the air inlet chamber and the air outlet chamber and is connected with the septum; the technology of the utility model is mainly characterized in that the utility model also comprises a pressure adjusting chamber that is connected with the other side of the septum and can adjust the air outlet pressure; the pressure adjusting chamber consists of a pressure adjusting valve body and a septum which is arranged between the air inlet chamber and the pressure adjusting chamber, and the pressure adjusting valve body is provided with an air inlet nozzle communicated with an air source. The utility model is characterized by effectively adjusting the matching ratio between the fuel gas and the air, leading the matching ratio between the fuel gas and air to be in linear state, and meeting normal usage of fuel tools by users, etc.
Description
Technical field:
The utility model relates to the gas ratio valve of a kind of Proportional valve, particularly a kind of household gas apparatus.
Background technique:
The gas ratio valve that existing household gas apparatus uses normally adopts electrically-controlled valve to control: the tolerance size of gas ratio valve is that the electrically-controlled valve size of current on the valve is controlled in proportion.When the combustion gas tool adopts gas ratio valve and blower fan to cooperate burning simultaneously, because gas ratio valve and blower fan speed of response separately are different, the proportioning of combustion gas and air meeting departs from linear state in adjustment process, thereby yellow fire appears easily, from unstable states such as flame, tempering, noises, influence the use of combustion gas tool.For overcoming these defectives, gas ratio valve is developed.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of gas ratio valve, and it can regulate the proportioning of combustion gas and air effectively, and making the proportioning of combustion gas and air is linear condition, satisfies the user and normally uses the combustion gas tool.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises the ratio valve body, air-inlet cavity, outlet chamber, barrier film, valve, air-inlet cavity is by the ratio valve body, barrier film, valve constitutes, outlet chamber is after air-inlet cavity and by the ratio valve body, valve constitutes, one side of barrier film links to each other with air-inlet cavity, valve links to each other between air-inlet cavity and outlet chamber and with barrier film, it comprises that also the can regulate that links to each other with the barrier film another side goes out the pressure regulating cavity of atmospheric pressure, described pressure regulating cavity is by the pressure regulation valve body, barrier film constitutes, barrier film is between air-inlet cavity and pressure regulating cavity, and the pressure regulation valve body is provided with the air inlet nozzle that communicates with air source.
Be provided with the spring that links to each other with the pressure regulation valve body with barrier film in the described pressure regulating cavity.
The utility model compared with prior art its beneficial effect is:
1, because adopting with air source, the utility model regulates the structure that pressure regulating cavity pressure comes the tolerance size of control ratio valve, so it not only has the ratio of common Proportional valve to regulate the tolerance function, and when the combustion gas tool adopts this Proportional valve and blower fan to cooperate burning simultaneously, when being air source with the air behind the blower fan, Proportional valve and blower fan speed of response are consistent, can regulate the proportioning of combustion gas and air effectively, making the proportioning of combustion gas and air is linear condition, satisfies the user and normally uses the combustion gas tool.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the annexation schematic representation of the utility model and blower fan.
Embodiment:
Shown in accompanying drawing 1, present embodiment includes ratio valve body 1, air-inlet cavity 2, outlet chamber 3, barrier film 4, valve 5, spring 6, pressure regulating cavity 7, pressure regulation valve body 8 and air inlet nozzle 9, air-inlet cavity 2 is by ratio valve body 1, barrier film 4, valve 5 constitutes, outlet chamber 3 is after air-inlet cavity 2 and by ratio valve body 1, valve 5 constitutes, one side of barrier film 4 links to each other with air-inlet cavity 2, valve 5 links to each other between air-inlet cavity 2 and outlet chamber 3 and with barrier film 4, pressure regulating cavity 7 is by pressure regulation valve body 8, barrier film 4 constitutes, barrier film 4 is between air-inlet cavity 2 and pressure regulating cavity 7, pressure regulation valve body 8 is provided with the air inlet nozzle 9 that communicates with air source, and spring 6 links to each other with barrier film 4 in pressure regulating cavity 7 and with pressure regulation valve body 8.When the air pressure in the pressure regulating cavity 7 increased, valve 5 moved to outlet chamber 3 directions, and the aisle spare between valve 5 and the ratio valve body 1 increases, and gas flow increases; Otherwise when the air pressure in the pressure regulating cavity 7 reduced, valve 5 moved to air-inlet cavity 2 directions, and the aisle spare between valve 5 and the ratio valve body 1 reduces, and gas flow reduces.
Shown in accompanying drawing 2, present embodiment includes this Proportional valve 10, sebific duct 11, blower fan 12 and burner assembly 13, and sebific duct 11 1 ends link to each other with the air inlet nozzle 9 of Proportional valve 10, and the other end links to each other with blower fan 12.When the air pressure of blower fan 12 increased, through sebific duct 11 and the air inlet nozzle 9 pressure transmissions pressure regulating cavity 7 to the Proportional valve 10, gas flow increased; Otherwise when the air pressure of blower fan 12 reduced, through sebific duct 11 and the air inlet nozzle 9 pressure transmissions pressure regulating cavity 7 to the Proportional valve 10, gas flow reduced; Thereby make Proportional valve 10 consistent with blower fan 12 speed of response.
