Abstract
The invention relates to a multipurpose automatic air regulating valve comprising a membrane, a pressure-bearing plate, a valve rod, a spring regulating seat, a valve shell, a valve plate and a valve port. The distance between the valve plate and the valve port is automatically regulated by utilizing the change of a gas pressure. When used for a burning appliance using a single-speed fan, the multipurpose automatic air regulating valve automatically controls the ratio of air quantity required for burning to gas flow by regulating partial air quantity. When used for an upward drawing type burner, the multipurpose automatic air regulating valve automatically control the air quantity required for burning by regulating short-circuit air quantity. When the multipurpose automatic air regulating valve is used for a downward blowing type (including a full premixing type) burner, a minimum-air quantity air inlet is reserved, and then the total air quantity is in proportion to the gas quantity by regulating the partial air quantity.
Description
Technical field
The present invention relates to a kind of fuel gas buring utensil GAS control gear.
Background technique
Most advanced and energy-conservation gas burner has adopted the GAS control system at present, or is called the GAS controller.No matter be electronic-type or air-driven type, all be not only will be with the rotating speed of electronic controller controls blower fan, but also must use the blower fan of variable-speed that cause technical sophistication, poor reliability and cost are high and can't penetration and promotion.
Summary of the invention:
The purpose of this invention is to provide a kind ofly, use the single speed blower fan to realize the device of combustion gas/air automatic ratio control, improve the combustion gas tool thermal efficiency without electrically-actuated throttle device.
For realizing purpose of the present invention, multipurpose automatic air regulating valve provided by the invention comprises: the combustion gas of diaphragm, bearing plate, valve rod, spring, spring adjustment seat, valve plate, valve port, valve casing/air automatic ratio control gear, the combustion gas that is provided by the outlet of the original Proportional valve of fuel gas buring utensil enter in the cavity between valve casing and the diaphragm; The pressure of combustion gas promotes motion of membrane, overcomes the active force of spring by bearing plate and valve rod, changes the distance between valve plate and the valve port, thereby regulates the size of air supply amount automatically.
As everyone knows, the square root of gaseous-pressure is directly proportional before the gas flow by the burner nozzle and the nozzle, is non-linear relation; Gaseous-pressure is directly proportional with the stroke of wind-regulating valve diaphragm again, and the stroke of diaphragm equals the stroke of valve plate, and under the constant situation of blast, the distance of valve plate and valve port is directly proportional with the flow of air again; But be to use the situation of single-speed motor blower fan, when changing the sectional area of air intake or exhaust outlet, the blast of blower fan changes, and promptly air quantity and air port sectional area are not linear relationship; Cancelling out each other of two kinds of non-linear relations regulated under the condition of air port aperture in part, and can realize burning required air quantity and gas flow are linear substantially, become proportional control.Its nonlinearity erron is less than using speed-changing draught fan control and because the error that other factors such as voltage functuation cause, can satisfying the efficient burning of very little excess air fully.
Purpose of the present invention, feature and advantage are under the situation of using the single speed blower fan, utilize the variation of gaseous-pressure to regulate the part air mass flow automatically, make required air mass flow and the gas flow of burning become linear relationship, realize GAS control.
Below in conjunction with example, be described further with reference to accompanying drawing
Description of drawings
Fig. 1 takes out with multipurpose automatic air regulating valve structure and fundamental diagram on being.1, bearing plate 2, valve rod 3, diaphragm 4,5, shell 6, combustion gas interface 7, spring seat 8, spring adjustment seat 9, valve port 10, valve plate 11, spring 12, nut 13, screw rod
Fig. 2 rouses down with multipurpose automatic air regulating valve structure and fundamental diagram.1, bearing plate 2, valve rod 3, diaphragm 4,5, shell 6, combustion gas interface 7, spring seat 8, spring adjustment seat 9, valve port 10, valve plate 11, spring 12, nut 13, screw rod 14, reserve minimum air-flow plate
Fig. 3 is that the present invention is used for the working principle on the odd test gas heating stove.1, wind-regulating valve 2, valve plate 3, valve port 4, exhaust fume collecting hood 5, blower fan 6, heat exchanger
Fig. 4 is the fundamental diagram on drum-type (the comprising full premix) gas heating stove under the present invention is used for.1, wind-regulating valve 2, valve plate 3, valve port 4, minimum air quantity are reserved regulator plate 5, blower fan
Illustrated in figures 1 and 2: combustion gas is introduced in the valve casing (5) by joint (6), gaseous-pressure makes diaphragm (3), and the cavity direction between (5) moves between diaphragm (3) and the valve casing towards enlarging, diaphragm (3) promotes the active force that bearing plate (1) overcomes spring (7), promoting valve plate (10) by valve rod (2) moves, reduce (on take out usefulness) or increase the distance of (drum with) down valve plate and valve port, thereby change from motion tracking with the fuel gas supply amount from air quantity.
Fig. 3 is the working principle that is used for odd test
Before multipurpose automatic air regulating valve is installed in blower fan (5) intake grill, heat exchanger (6) afterwards (generally all being on the exhaust fume collecting hood (4)) regulate the size of burning required air quantity by regulating the given short circuit wind air of heat exchange (do not participate in burning and) amount.
When the oepration at full load of fuel gas buring utensil, gaseous-pressure is the highest, wind-regulating valve plate (2) and valve port (3) closure, air must enter from the burner bottom, is the maximum quantity of wind state, when the little load operation of utensil, gaseous-pressure reduces, and valve plate (2) is opened certain distance with valve port (3) according to the pressure of combustion gas, and portion of air enters blower fan (5) by the valve port (3) of wind-regulating valve (1), thereby the negative pressure absolute value in the reduction firing chamber reduces the air quantity that enters burner.Promptly utilize air stream to form the mode of short circuit, reduce the required air quantity of burning, realize GAS control, reach the purpose that improves the thermal efficiency.
Fig. 4 is used for the working principle of drum-type (containing fully-premixed) burner down.
Multipurpose automatic air regulating valve is directly installed on the intake grill place, and when oepration at full load, gaseous-pressure is the highest, wind-regulating valve (1) aperture maximum; When entering the minimum load operation, gaseous-pressure reduces, valve plate (2) and valve port (3) closure, and minimum air quantity is entered by the minimum air quantity intake grill of the reservation on the valve port (3).Running state between maximum load and minimum load changes by gaseous-pressure, the distance of automatic regulating valve plate (2) and valve port (3), and total air mass flow and gas flow are linear, realize GAS control.
On take out with multipurpose automatic air regulating valve to be identical with following drum with the multipurpose automatic air regulating valve critical piece, only to be that valve port is different with the assembly direction and the position of valve plate.
