Wheel type quick-closing gate

Abstract

The invention discloses a wheel type quick-closing gate and relates to a high-flow gate capable of precisely controlling the flow. The wheel type quick-closing gate comprises a controller, a gate frame, a round gate and a driving device, wherein the gate and the gate frame are sealed and jointed through liquid, and the gate can be rotated relative to the gate frame; a port which has an area smaller than the gate semi-circle and is arranged in the gate semi-circle is arranged on the gate; the half lower part of the gate frame is provided with a channel, the shape of which is the same as that of the port; the periphery of the gate is provided with gear rings; the driving device is engaged with the gear rings through gears; and the controller is connected with the driving device. The opening quantity of the wheel type quick-closing gate can be controlled, and opening and closing actions are quick and sensitive. A sensor used for sensing the liquid level height is also arranged, and when the liquid level of any side reaches or is lower than a set requirement, the gate can be commanded to open / close. In addition, some sewage treatment plants and chemical plants have requirements on the pH value of overflowing liquid, thus the gate is also provided with a sensor for detecting the pH value so as to meet and requirement.

Description

technical field [0001] The invention relates to a gate, in particular to a large flow gate capable of precisely controlling the flow. Background technique [0002] In some sewage treatment plants and chemical plants, some flow passages have begun to be closed. If valves are used on the closed passages, firstly, the control is difficult, and secondly, the cost is high. Although there are valves for precisely controlling the flow, the flow is small and cannot meet the flow requirements of the above-mentioned occasions. Sometimes, there are still some large-sized debris in the fluid, which will block the above-mentioned valve. Contents of the invention [0003] In view of the above problems, the present invention provides a wheel-type quick-closing gate with large flow rate and high control precision. [0004] The technical solution of the present invention is: comprising a controller, a gate frame, a circular gate and a driving device, the gate and the gate frame are liqui...

Problems solved by technology

[0002] In some sewage treatment plants and chemical plants, some flow passages have begun to be closed. If valves are used on the closed passages, firstly, the control is difficult, and secondly, the cost is high.

At present, although there are valves that precisely control the flow rate, the flow rate is small and cannot meet the flow requirements of the above occasions.

Sometimes, there are still some large-sized debris in the fluid, which will block the above valve
