Description

Valve before the general mood interlock energy-saving range

Technical field

The utility model relates to a kind of air feed, air-supplying valve system of blowing type gas kitchen range, especially can pass through a valve handle, makes air feed valve and air-supplying valve sync equalizing, reconciles in proportion and supplies with burner, reaches energy saving and the purpose that simplifies operation.

Background technique

1: air-supplying valve; Present on the market blowing type gas kitchen range, the air-supplying valve of use generally adopts the O type ball valve of DN15; Its opening diameter is 15MM; The maximum flow sectional area is 176.6 square millimeters during its standard-sized sheet, and present common liquid gas air blast range, the diameter of nozzle bore is about 2.0MM.Its actual internal area only has 3.14 square millimeters, is less than 3% of DN15 ball valve actual internal area, therefore: make that the effective in theory adjusting angle of valve handle can only be in 10 degree.So why, reach maximum to this valve; Can gas cooker proper functioning? Be because the valve back has all been gone here and there a current limliting valve or blast nozzle and done current limliting before the general kitchen range; Even, do not have the gas that is limited above current limliting valve or blast nozzle yet and flow out so reach 90 degree (maximum) to valve before the kitchen range.It is thus clear that this valve is to transfer big fire easy, it is difficult to turn fire down, no wonder (that) existing Draught gas burner, because of being difficult to control accurately little fire, when making igniting big fire soaring, the time fire and burning accident generation arranged.Often fire extinguishing again when turning fire down, the time of promptly having wasted has been wasted a large amount of energy again.

2: the air feed valve.Now the market for gas stove blast air valve, most of them or individually adjustable, every fire regulation, must be on the air valve and valve once the necessary adjustments so that operation as the trouble.Each in addition adjusting also has no method to guarantee that air feed and combustion gas can be transferred to optimal proportion, and cook's also not free at all conscientious adjusting repeatedly when cooking.Gas is little, wind is big, heat can be gulped down mistake by wind, even fire is blown out.Wasted the energy.Gas is big, wind little firepower empty.It is insufficient to burn, and has promptly wasted the energy, has polluted environment again.Though either way can burn, not the best proportioning of general mood, the operational inconvenience of having returned user Dai Lai.

3: general mood interlock valve: all the time, yearning has a kind of general mood interlock valve in the industry, simplifies operation.So occurred on the market, standard valve and air-valve with forms such as chain, gear or coaxial valves, be directly connected to the general mood interlock valve of forming together.But can know from principle,, also can not get a desired effect although the flow characteristics of these two valves is in full accord; Reason is very simple; Because the flow of two valves is not reciprocity, the flow of gas valve is too big, when gas valve reaches 10 when spending; The maximum air demand that has just surpassed cooking stove, and air-valve reaches 10 wind supply quantities when spending and just has only about 10% of cooking stove required airflow.Combustion gas has supplied more than 80% than wind more, serious disproportion, and the combination of these two valves is not reconciled not in proportion.Effect is very poor, has also wasted a large amount of energy, so use very few.

Summary of the invention

In order to overcome existing Draught gas burner; Kitchen range early gate actual internal area is too big; The deficiency that air-valve and air valve also will be regulated respectively; The utility model provides valve before a kind of general mood interlock energy-saving range, is made up of an air feed valve, air-supplying valve and synchronous connecting device, and it is characterized in that: the opening in the air-supplying valve is microscler opening.(can know that by principle this opening also can be combined by a plurality of apertures).Therefore the problems referred to above have effectively been solved.It can pass through a valve handle, makes the synchronous interlock of air feed valve and air-supplying valve, and the mode of proportionally regulating is supplied with burner, has reached energy saving and the purpose that simplifies operation.

The technological scheme that solves the problems of the technologies described above and adopt is:

1: utilize existing technology and technology of producing ball valve, in existing O shape ball valve, the opening of circle is improved to microscler opening on the spheroid.Purpose is the discharge value of O type valve, is decreased to the required discharge value of burner.The flow proportional of air-supplying valve and air feed valve is equated.If the required discharge value of burner is 6mm square.Just become a long 15mm to the opening of DN15 valve, " elongated hole " of wide 0.4mm (15mm is the diameter of DN15 valve opening).Reach 90 when spending at valve like this.Just have 6mm square discharge value.Reconcile precision so improved (firepower) of valve greatly.Also satisfied flow requirements.

In like manner we also can adopt another method to achieve the above object, and are about in the O shape ball valve, and the seal ring on spheroid both sides changes into and the close-fitting hemisphere of spheroid, with the opening of the circle on its original seal ring, changes microscler opening into again.

2: can know from principle, if change " elongated hole ", local width, (being the shape at edge) just can be realized the adjustment to valve characteristic curve and flow easily.So can imitate out the characteristic of some valves easily, be convenient to Combination application.For example open a wide slotted hole, be linear output.If it is wide to open a first half, latter half of narrow elongated hole promptly is similar to fast katal property.If it is narrow to open a first half, latter half of wide elongated hole promptly is approximately equal percentage characteristics.Can know that according to principle " elongated hole " just realize the shape that above-mentioned purpose is the most succinct in addition, it also can be arranged in a combination according to the sequencing of valve conducting is irregular by one or more hole.

3: utilize the method for machineries such as existing technology such as gear, chain or coaxial valve, two characteristic unanimities, the flow contrast equates (the air feed valve is with " elongated hole " air-supplying valve) synchronous connecting together.Can put into practice synchronous interaction, the purpose of regulating in proportion.

Owing to adopted such scheme, made the firepower of Draught gas burner regulate disposable completion, realized the function that real wind-gas linkage is regulated in proportion.Purposes easy to use, energy-conserving and environment-protective have been reached.This valve be not limited only to wind-gas linkage, also can be used for other the interlock etc.More can be applied to other separately to flow or the higher occasion of characteristic requirements.
