Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of improved can reduction greatly to use the valve cost, and uses reliably non-damageable BAF.
The utility model purpose realizes that main the improvement is with bigbore water inlet of BAF and water outlet motorized valve, changes the gas control outlet valve by two little electrically-controlled valve controls into, not only reduced and used the valve cost, and because basic movement-less part, reliable operation has also reduced maintenance cost.Specifically, the utility model BAF, the BAF that comprises many ponds paired running, it is characterized in that each filter tank water intaking valve and back flushing outlet valve at least, reaching total outlet valve is the gas control outlet valve, and said gas control outlet valve is by stretching the lid shape air chamber cover that exceeds water shoot under water shoot and the top, air inlet electrically-controlled valve and exhaust electrically-controlled valve on the lid shape air chamber cover, the water seal elbow that connects water shoot is formed, and the said gas control outlet valve draining mouth of pipe is lower than the liquid level setting.
Utility model gas control outlet valve, owing to have the air chamber space between lid shape air chamber cover and water shoot, water shoot is kept sealing gland by the water seal elbow again, thereby can be by regulating air chamber spatial air capacity, make the interior liquid level of gas control water outlet valve gap shape air chamber cover be higher or lower than the draining mouth of pipe, thereby form draining or stop two kinds of working ordeies of draining.When the needs valve is opened outside draining, open the vent valve on this gas control outlet valve, air in the air chamber space is discharged discharge, the water level in the gas control water outlet valve gap shape air chamber cover is risen, the draining mouth of pipe is submerged in the water, water is just discharged by water shoot; Need close this valve,, open intake valve, in air chamber, be pressed into air, the air chamber median water level is forced down, the draining mouth of pipe be surfaced, thereby stop water outlet by closing vent valve.
The said gas control outlet valve of the utility model draining mouth of pipe is lower than the liquid level setting, mainly refer to its draining mouth of pipe is set is lower than liquid level of gas control outlet valve, guaranteeing and the draining mouth of pipe to be flooded or expose liquid level by regulating sealing gland, thereby reach gas control water outlet basic function.
Utility model is owing to adopt the gas control outlet valve to substitute former bigbore electrically operated valve, as BAF water inlet, water outlet and back flushing valve, greatly reduce and use the valve cost, and because basic movement-less part, so be difficult for breaking down, need not keep in repair substantially; And can make full use of the source of the gas of the biochemical usefulness of BAF, do not need to set up separately source of the gas again.Utility model adopts the heavy caliber motorized valve than prior art, and is simple in structure, less investment, and reliable operation does not need maintenance maintenance substantially.Utility model gas control outlet valve device can also be used for the similar water treatment unit in addition.
Below in conjunction with an embodiment, further specify utility model structure and working process, but embodiment not the qualification to utility model.
