Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, The present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to explain this hair It is bright, it is not intended to limit the present invention.
As shown in Figure 1, the embodiment of the invention provides a kind of control and regulation methods of proportioning valve, this method comprises: ratio Valve is under the control of maximum current, and when being in maximum combustion gas output quantity, water heater is run under maximum power, determines most High-power lower gas nozzle output end air pressure is maximum power lower water-heater operating air pressure Pmax, and according in preset time The size and inflow temperature Lmax1 and leaving water temperature Lmax2 of water flow, determine gas heater in current environment maximum work Load Qmax under rate.
Proportioning valve is under the control of minimum current, and when being in the smallest combustion gas output quantity, water heater is under minimum power Operation determines that the air pressure of gas nozzle output end is minimum power lower water-heater operating air pressure Pmin under maximum power, and according to The size of water flow and inflow temperature Lmin1 and leaving water temperature Lmin2, determine gas heater current in preset time Load Qmin under environment minimum power.
Water heater determines blower electric current and proportioning valve electric current according to the corresponding relationship of preset load and blower electric current Corresponding relationship.
Gas heater usually passes through the output quantity of the form control combustion gas of proportioning valve, and the flow of proportioning valve passes through electric current Size is controlled, the corresponding relationship of predetermined current and proportioning valve opening-closing size in water heater, because under standard environment, The opening-closing size of proportioning valve directly determine combustion gas generate load, and load caused by the size and combustion gas of electric current it Between be linear relationship, so gas heater is stored with the linear relationship between electric current and preset value, held according to water heater needs The size of the load adjustment proportioning valve of load, in actual use, because of the variation of height above sea level, supply gas pressure is too low to be led Cause the different thermal efficiency for leading to combustion gas itself of quality of secondary pressure different in different time period and combustion gas itself Difference, when being opened by current control proportioning valve to default size, gas nozzle can not provide suitable fuel gas, lead The load of pyrogenicity hydrophone generates difference with preset value.
Exhaust fan is used to help the circulation of air, provides suitable air for burning, and exhaust gas is discharged, prevents one The pernicious gases such as carbonoxide retain, and current control of the revolution of exhaust fan by load on blower, carry with water heater Load be adapted, one provides suitable air inflow and capacity, and the electricity loaded on the load and proportioning valve of water heater carrying Cleanliness is related, so the revolution of exhaust fan can determine that water heater is preset with exhaust fan by the electric current loaded on proportioning valve Revolution s=F (I) wherein I is electric current of the load on proportioning valve, row is adjusted according to the proportionate relationship between Qmax and Qmax0 The revolution s of gas fan, so that s=jF (I).In this way, exhaust fan can work in the case where meeting the revolution to match with water heater.
Further, water heater determines that current gas pressure P1 is that sea-level atmosphere is pressed under p0 and maximum power, water heater work Make under air pressure Pmax and minimum power, water heater working air pressure Pmin is in the upper and lower limits of the secondary pressure of proportioning valve.
Water heater makes according to the load adjustment preset value under the load and minimum power under maximum power under environment in the ban Obtain Qmax0=Qmax and Qmin0=Qmin.
Water heater is according to the load under the load Qmax and current environment minimum power under current environment maximum power Gap between Qmin and preset value is greater than first threshold, according to the load absolute presupposition value under current environment maximum power Coefficient j=Qmax/Qmax0 or j=Qmin/Qmin0 adjust the corresponding relationship of preset blower electric current and proportioning valve electric current.
According to the operating air pressure Pmax and Pmin and air pressure P1 of current environment, determine water heater in the maximum electricity of shut-off valve Secondary pressure Pmin1 of the secondary pressure Pmax1 and water heater flowed down under shut-off valve minimum current, and according to Pmax1 with The difference of preset value Pmax0 is within 50 percent, and according to the difference of Pmin1 and preset value Pmin0 5 percent Within ten, according to the proportionality coefficient of Pmax1 and Pmax0 or the proportionality coefficient of Pmin1 and Pmin0, i=Pmax1/Pmax0 or i =Pmin1/Pmin0 adjusts the corresponding relationship of blower electric current and proportioning valve electric current, so as to adjust rotation speed of the fan and proportioning valve electric current Corresponding relationship so that s=iF (I).
Water heater obtains current gas pressure in debugging mode first, determines that current gas pressure is sea-level atmosphere pressure, Threshold value is preset in practical operation, when the pressure that pressure sensor detects is within preset threshold range, it is determined that current Air pressure is sea-level atmosphere pressure, and later, water heater is run under maximum power, and pressure sensor detects the pressure of combustion gas nozzle Power size is maximum power lower water-heater operating air pressure Pmax, and according to the water flow heated in preset time period, and The temperature change of inlet and outlet determines the load Qmax of water heater;Similarly water heater determines minimum power lower water-heater Operating air pressure Pmin and Qmin, and it is hidden not generate safety within the pressure limit that water heater is set by Pmax and Pmin Suffer from, then adjusts the water heater upper loading limit in preset value and make Qmax0=Qmax and adjust the load of the water heater in preset value Lower limit Qmin0=Qmin redefines the linear relationship between the electric current on proportioning valve and the load of water heater carrying.Reach Accurately control the effect of combustible gas output quantity and effectively control hot water water temperature.
When the coefficient j of load absolute presupposition value under current environment maximum power is greater than preset value, illustrate that water heater is being worked as Under preceding gaseous-pressure, the load of generation and default load are inconsistent, and water heater uses combustion gas and standard combustion gas the combustion heat it It is upper that there is larger difference, it keeps original rotation speed of the fan that can cause the hidden danger of extinguishing of flame at this time, adjusts proportioning valve electric current and wind Corresponding relationship between electromechanics stream, adjusting blower electric current according to coefficient j influences rotation speed of fan, matches with water heater load.
The secondary pressure that revolving speed of the exhaust fan in work and water heater generate is adapted, and too fast revolving speed may cause Flame-out, under use environment, the revolving speed of exhaust fan is corresponding with electric current of the load on proportioning valve, corresponding with secondary pressure, Load when the electric current on proportioning valve and the corresponding relationship between secondary pressure generate variation, water heater adjust exhaust fan revolving speed and The preset value for loading the corresponding relationship between the electric current on proportioning valve, when load is in the electric current on proportioning valve and between secondary pressure Corresponding relationship produce large change, then illustrate supply end gas supply produce exception, lead to pressure anomaly, need using Person is handled.
It is as shown in Figure 2:
Step S100: the load of proportioning valve maximum output and minimum output under current environment is determined.
Step S200: the proportionate relationship k of current atmospheric pressure and standard atmospheric pressure is determined.
Step S300: the corresponding relationship of load and proportioning valve electric current is determined.
Step S400: the bound ratio j of water heater load and default load is determined.
Step S500: it determines the secondary pressure of gas nozzle and presets secondary pressure bound ratio i.
Step S600: the relationship between blower electric current and proportioning valve electric current is modified according to payload.
In another embodiment, water heater determines that current gas pressure is not equal to sea-level pressure, and determines current gas Press coefficient k=P1/P0 relative to sea-level pressure, coefficient k and preset value according to current gas pressure relative to sea-level pressure Load Qmax is compared under the product kQmax0 of load under maximum power and current environment maximum power, determine kQmax0 with Difference between Qmax is less than preset value, then corrects preset value according to load Qmax under current environment maximum power, so that Qmax0=Qmax.According to current gas pressure relative to the coefficient k of sea-level pressure and multiplying for the load under preset value minimum power Product kQmin0 is compared with load Qmin under current environment maximum power, and it is default to determine that the difference between kQmin0 and Qmin is less than Value then corrects preset value according to load Qmin under current environment maximum power, so that Qmin0=Qmin.
In another embodiment, the operating air pressure Pmax and Pmin under water heater maximum power is the two of proportioning valve Except secondary pressure upper and lower limits, determine for unsaturated vapor.
In actual use, because design of pipe networks is lack of standardization and concentrated with gas and can generate the phenomenon of air pressure deficiency, By judging under water heater maximum power with the operating air pressure under minimum power not in the upper and lower limits of proportioning valve, especially It is less than the low pressure limit of proportioning valve, is determined currently for unsaturated vapor.Controller can be sent out in such a way that Feng Ming, display screen are shown etc. Early warning requires user maintenance out.
In another embodiment, according to the operating air pressure Pmax and Pmin and air pressure P1 of current environment, heat is determined Secondary pressure Pmax1 and water heater secondary pressure under shut-off valve minimum current of the hydrophone under shut-off valve maximum current Pmin1, and it is greater than 50 percent or Pmin1's and preset value Pmin0 according to the difference of Pmax1 and preset value Pmax0 Difference is greater than 50 percent, determines gaseous-pressure exception.
In another embodiment, difference between kQmax0 and Qmax be greater than preset value or kQmin0 and Qmin it Between difference be greater than preset value, determine that Qmax or Qmin are abnormal.
