    • A compact water level regulator which may be used with a water catcher and/or with a planter. A case includes side and upper surfaces of the case form an airtight chamber having an open bottom, a filling port plug, an air vent hole, and an air inlet in a side bottom. A first float is installed on the upper surface of the case and includes a ventilation plug. The ventilation plug releases and shuts the air vent hole as the first float raises and falls by the buoyancy thereof in response to the level of water outside the case. A second float is installed inside the case and includes a water filling port plug. The water filling port plug shuts the water filling port by buoyancy thereof in response to the water level inside the case. When water level falls enough to open the air inlet to the atmosphere, the second float falls thereby disengaging the water filling port plug and opening the water filling port.
    • 一种紧凑的水位调节器,可与捕水器和/或与播种机一起使用。 壳体包括壳体的侧表面和上表面,形成具有开口底部的气密室,填充口塞,排气孔和侧底部的空气入口。 第一浮子安装在壳体的上表面上并且包括通风塞。 随着第一浮子由于外壳外的水平面的升高而浮起并且被浮力下降,通风塞释放并关闭排气孔。 第二个浮子安装在壳体内,并包括一个注水口塞。 充水口插塞响应于壳体内部的水位,通过浮力将其填充水口关闭。 当水位下降到足以打开大气的入口时,第二个浮子就会下降,从而使注水口堵塞并打开注水口。
