Wheel-type quick-closing gate

轮式速闭闸门

Abstract

A wheel-type quick-closing gate relates to a large flow gate capable of controlling the flow rate accurately and comprises a controller, a gate frame, a round gate and a driving device; the gate is in liquid seal fit with the gate frame and can rotate relative to the gate frame; a through port is arranged in a gate semicircle and the area of the through port is smaller than the area of the gate semicircle; the lower half part of the gate frame is provided with a channel matched with the through port in shape; a gear ring is arranged on the periphery of the gate, the driving device is meshed with the gear ring by a gear, and the controller is connected with the driving device. The wheel-type quick-closing gate has controllable opening degree, realizes quick and sensitive opening and closing actions. The wheel-type quick-closing gate is provided with an inductor for sensing the liquid level, and the inductor can instruct the gate to open/close when the liquid level in any side reaches or is under the preset liquid level; besides, as sewage treatment plants and chemical plants have requirements on the PH value of the flowing liquid, the wheel-type quick-closing gate also can be provided with a PH value inductor for meeting the requirements.
轮式速闭闸门。涉及一种能精确控制流量的大流量闸门。包括控制器、闸框、圆形的闸门和驱动装置,所述闸门与闸框液密封贴合,且闸门能相对于闸框旋转;在闸门上设有面积小于闸门半圆,且处于闸门半圆之内的通口;所述闸框的下半部设有与所述通口形状一致的通道;所述闸门的周边设有齿圈,所述驱动装置通过齿轮与所述齿圈相啮合,所述控制器与所述驱动装置相连。本实用新型开启量可控,开启、闭合动作迅速、灵敏。还设置了用于感应液位高度的感应器,无论那一侧的液位达到或低于设定要求,即可指令本实用新型的闸门开启/关闭;此外,在一些污水处理厂、化工厂,对过流液体的酸碱度有要求,本实用新型还设置了检测酸碱度的感应器,以满足上述要求。
