Abstract

Electrically controlled outlet valve for the fuel gas distribution and control system of ceramic furnace, comprises a valve housing fixed with a valve shaft in the middle, characterized in that the valve housing is provided with a strip curved air outlet at the upside, the valve shaft is fixed with a strip curved valve plate capable of opening or closing the strip curved air outlet, and the valve housing is fixed with a motor output gear of which on the output shaft is engaged with a reduction gear on the external end of the valve shaft. The utility model controls the distribution volume through controlling the open and close statues of the valve port by the motor through the distribution and control system to achieve the controllability, scientificity and accuracy of the distribution and to save the energy above 30%.

Description

Ceramic kiln combustion gas air-distribution control system is automatically controlled to go out air-valve

Technical field

The utility model relates to the valve that a kind of electronic control adjusts air quantity.

Background technique

Ceramic product needs to consume a large amount of gas energies in sintering procedure, its fuel cost accounts for more than 50% of ceramic product cost at most, be energy saving, reduce cost, people have carried out continuous improvement to furnace combustion energy saving technology, the main method air of in combustion process, in stove, providing and delivering exactly wherein, combustion gas is fully burnt, but only limit to utilize the drainage effect air distribution of burner at present, its air distribution amount is uncontrollable, do not accomplish accurately to control the air distribution amount by the combustion process requirement, energy-saving effect is bad.

Summary of the invention

The purpose of model utility is to provide that a kind of ceramic kiln combustion gas air-distribution control system is automatically controlled goes out air-valve, this goes out air-valve and is used for to the combustion gas mixing inner air-distributing, as shown in drawings, the utility model comprises a valve chest, valve chest two ends up and down is useful on the flange that inserts air-distribution control system, a valve shaft is fixed at the valve chest middle part, the valve shaft outer end is exposed at outside the valve chest, it is characterized in that there is a strip circular arc exhaust outlet valve chest upper end, fix a strip circular arc valve block on the valve shaft, strip circular arc valve block is positioned at the inboard of strip circular arc exhaust outlet, can open or closed circular arc exhaust outlet, motor of valve chest outer fixing is fixed an output gear on the motor output shaft, a reduction gear is fixed in the valve shaft outer end, and reduction gear is meshed with motor output gear.The lower end intake grill was connected with blower fan when the utility model used, the upper end exhaust outlet is connected with fuel gas mixer, combustion gas behind the air distribution is sent in the kiln, the utility model is passed through the opening state of Electric Machine Control valve port according to combustion requirements by air-distribution control system, and then control air distribution amount, controllability, science and the accuracy of air distribution have been realized, important means is provided for ceramic kiln is energy-conservation, test shows, but energy saving more than 30% when using ceramic kiln combustion gas air-distribution control system control kiln burning of the present utility model.

Description of drawings

Accompanying drawing is the utility model plan view.Among the figure: 1, motor, 2, motor output gear, 3, strip circular arc exhaust outlet, 4, strip circular arc valve block, 5, valve chest, 6, reduction gear, 7, valve shaft, 8, indicator panel, 9, dust-proof cover.

Embodiment

Valve chest (5) middle part is valve shaft (7) fixedly, the valve shaft outer end is exposed at outside the valve chest, the circular arc of the strip circular arc exhaust outlet (3) on the valve chest is the center of circle with the valve shaft, becomes 120 degree central angles with valve shaft, and the strip circular arc valve block (4) on the valve shaft becomes 125 degree central angles with valve shaft.The valve shaft end is also fixed a circular indicator panel (8), and colour code is arranged on the indicator panel, and a dial is arranged on the valve chest, and colour code and dial constitute the valve state indicator, and the reduction speed ratio of output gear and valve shaft outer end reduction gear is 1:4.A dust-proof cover of valve chest outer fixing (9) gets up motor (1), output gear (2) and reduction gear (6) cover.

Claims (1)
