Description
Известны дозаторы дл введени смачивател в оросительный водопровод , выполненные в виде резервуара, подсоединенного к участку водопровода. Однако эти дозаторы не обеспечивают посто нную концентрацию смачивател прн переменном расходе и давлении воды.Dispensers are known for introducing a wetting agent into an irrigation water supply system, made in the form of a reservoir connected to a water supply section. However, these dispensers do not provide a constant concentration of the wetter with a variable flow rate and water pressure.
Предлагаемый дозатор отличаетс от известных тем, что он снабжен автоматическим устройством, выполненным в виде шайбы и конического подпружиненного поплавка. Такое выполнение агрегата обеспечивает стабильную дозировку смачивател при изменении расхода воды.The proposed dispenser differs from the known ones in that it is equipped with an automatic device made in the form of a washer and a conical spring-loaded float. This embodiment of the unit provides a stable dosage of the wetting agent when changing water flow.
На чертеже изображена схема дозатора с авторегулировкой.The drawing shows the diagram of the dispenser with auto-adjusting.
В герметичном сосуде / помещаетс смачиватель (ДБ концентрации 40%). При движении воды в водопроводе 2 на местном сопротивлении - шайбе 3 создаетс перепад давлени , под действием которого из сосуда по трубке 4 смачиватель вытесн етс в водопровод, а в верхнюю часть сосуда поступает вода. Разность удельных весов смачивател и воды (первый т желее) и мала скорость диффузии смачивател в воду (менее 10 мм в сутки при температуре 20°) исключают смешивание воды со смачивателем.A wetting agent is placed in a sealed vessel (DB of 40% concentration). When water moves in the water supply system 2 at a local resistance — the washer 3 creates a pressure drop, under the action of which the wetting agent is forced out of the vessel through the pipe 4 into the water supply system, and water flows into the upper part of the vessel. The difference between the specific weights of the wetter and water (the first is more desirable) and the low rate of diffusion of the wetter into water (less than 10 mm per day at a temperature of 20 °) exclude the mixing of water with the wetting agent.
Стабильность дозировки смачивател обеспечиваетс следуюш,им образом. В шайбе 3 установлен конический поплавок 5, удерживаемый пружиной 6. При увеличении расхода воды кольцевой зазор между шайбой и поплавком увеличиваетс и перепад давлени в этом устройстве не будет пропорционален квадрату расхода воды; между расходом воды и перепадом давлени наблюдаетс линейна зависимость. При определенных размерах шайбы, поплавка и пружины така зависимость обеспечиваетс , например, при расходе воды от 5 до 100 л/мип.The dosage stability of the wetting agent is ensured in the following way. The washer 3 has a conical float 5 held by the spring 6. As the water flow increases, the annular gap between the washer and the float increases and the pressure drop in this device will not be proportional to the square of the water flow; a linear relationship is observed between water flow and pressure drop. At certain sizes of washers, float and springs, such dependence is provided, for example, at a water flow rate of 5 to 100 liters / mip.
