Background technology
Industrial Boiler is indispensable thermal powerplant, and at present China has 79.3 ten thousand of Industrial Boilers, is Industrial Boiler production and uses first big country.According to market prediction, the Eleventh Five-Year Plan period, industrial boilers in China normal year demand will remain on 120,000 and steam about ton, and Industrial Boiler industry production ability remains on 150,000～200,000 and steams more than the ton, and the Industrial Boiler growth rate of especially big capacity, high parameter is very fast.Report according to the energy-conservation investigation group of heating system of Bureau of Energy of National Development and Reform Committee, on every steaming ton Industrial Boiler 4.57 Automatic steam trap Traps are installed, estimate that the Eleventh Five-Year Plan period newly-increased Industrial Boiler is 36.56 ten thousand (life-span of Automatic steam trap Trap is 8000～12000 hours) to the requirement of Automatic steam trap Trap, add the old boiler transformation and also need steam valve, in view of this, the Eleventh Five-Year Plan period Industrial Boiler heightens to the demand of Automatic steam trap Trap door, greatly about about 4,000,000.
As one of important universal accessories of Industrial Boiler, Automatic steam trap Trap in the production development starting of China than later, domestic based in producing, low-pressure vapor drain valve, parameter is low, poor performance, the life-span is short, research technique is poor.Every life-span of Automatic steam trap Trap of producing as developed countries is leaked the vapour rate below 3% more than 1 year, and the steam pipe system thermal efficiency is more than 50%; And about 2,200,000 of China's Automatic steam trap Trap annual productions, average every life-span less than 1 year is generally leaked the vapour rate about 6%, and the steam dispersion tube thermal efficiency is about 30%.China's Automatic steam trap Trap all can not satisfy the needs of domestic market on output and quality and kind.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of new electronic control steam trap is provided, this automatically controlled steam trap is simple in structure, dependable performance, energy-conserving and environment-protective, easy to maintenance, cost of use is cheap.
The purpose of this utility model is achieved through the following technical solutions: the new electronic control steam trap, it comprises water tank, automatically controlled position switch assembly and draining valve assembly, be provided with ball float in the described water tank, the top of ball float connects floating ball rod, the top carry magnet of floating ball rod; The bottom of described automatically controlled position switch assembly is provided with lower limit magnetic force induction switch, and top is provided with upper limit magnetic force induction switch, and lower limit magnetic force induction switch is connected with the control relay group respectively with upper limit magnetic force induction switch; Described draining valve assembly comprises magnetic valve and draining valve, and draining valve connects compressed air piping, is connected in series magnetic valve in the compressed air piping, and magnetic valve is connected with the control relay group by control line.
The top of water tank is provided with the condensate water water inlet pipe, and the bottom of water tank is provided with the condensate water outlet pipe, and draining valve is installed in the pipeline of condensate water outlet pipe.
Operation principle of the present utility model is roughly: steam is through entering steam trap water tank with waste hot steam through the condensate water water inlet pipe with the condensate water that produces behind the hot equipment, cause the rise and fall of water tank water level, the ball float position is changed up and down, and drivening rod top magnet moves.When the water level rising, when magnet moved to the upper limit magnetic force induction position of the switch, upper limit magnetic switch was opened, and the actuating of relay makes the magnetic valve energising, and compressed air enters the draining valve assembly, and cylinder intake is opened drain plug, the beginning draining.When water level was reduced to the lower limit magnetic force induction position of the switch, the lower limit magnetic switch was opened, and relay work makes magnetic valve release electricity, and drain plug is closed in the cylinder action, and water tank continues water storage.
The beneficial effects of the utility model are:
(1) can realize multiple computer desk control, control board quantity can be from several to tens, and multiple computer desk control reduces heat energy loss, energy savings;
(2) automatically controlled steam trap is simple in structure, and dependable performance is easy to maintenance, and cost of use is cheap, saves cost more than 50% than Free Float Type Steam Trap;
(3) help the recessed receipts utilization of condensate water, condensate water reclaims and is used for boiler feed water, both can reduce the boiler feed water amount, can increase inflow temperature again, reduces boiler heating energy consumption.
