Description
Technical field
The invention relates to the general mood synchronous control valve of a kind of control valve of commercial gas kitchen range, particularly a kind of combustion gas and air intake synchronization regulation, exportable fourth gear power in proportion.
Background technique
Commercial gas kitchen range are slow down according to the difference of region, the style of cooking, vegetable or tune up temperature rise speed in cooking process.Can not exceed standard with the normal CO that burns during same general mood synchronization control valve regulation each section of demand power between 8kw-45kw, this is an industry difficult problem, is also the tidemark that industry people pursues.Gas valve and the air valve great majority of current commercial gas kitchen range control combustion are separate operation, first open after air valve is dried in advance and light a fire, open gas valve, then regulate air valve air output.This kind of mode of operation has the following disadvantages: one is that operation uses inconvenience, requires high, easy misoperation, there is serious potential safety hazard to operator; Two is due to manual separate operation, and random large, can only operate by rule of thumb, combustion gas and air are difficult to accurate proportioning; If little air, fuel gas buring is insufficient, and not only energy utilization rate is low, also produces the toxic and harmfuls such as CO, and befouling environment; If air is many, heat can be absorbed by wind takes away loss, and combustion gas is not completely burned the firing chamber that is just blown out, and is even blown out by fire, namely wastes the energy, can produce the harmful gases such as CO, befouling environment yet.
Although market there are the commercial gas kitchen range of gas valve and air valve interlock, general gas valve and air valve are passed through directly connect to form wind-gas linkage valve by chain, gear or coaxial valve mode.But from principle, although the flow characteristics of these two valves is completely the same, also can not get a desired effect; Its reason is that the flow of two valves is not reciprocity, and the flow of gas valve is too large; When gas valve is opened to 10 degree, just exceed the maximum air demand of kitchen range.And air valve and required air quantity ratio differ greatly, can not meet the needs of air output far away, cannot regulate by best combustion gas and air ratio at all.Moreover, when gaseous-pressure changes, do not finely tune regulating gas amount.Cause the harmful gases such as firing effect is poor, combustion efficiency is low, CO to exceed standard seriously, befouling environment is serious, constrains applying of product.
For the problems referred to above, many manufacturers and knowledgeable people have carried out development, but not yet have comparatively ideal product to emerge so far.
Summary of the invention
