Valve body device capable of automatically controlling flow velocity

Abstract

The invention relates to the related field of novel valve bodies, and discloses a valve body device capable of automatically controlling flow velocity. The device comprises a valve body, wherein a vertically-through pipeline is arranged in the valve body, a feedback cavity is arranged on the right side of the pipeline, a centrifugal wheel cavity is arranged on the upper side of the feedback cavity, a spline cavity is arranged on the upper side of the centrifugal wheel cavity in a communicating manner, a display cavity is arranged on the upper side of the spline cavity in a communicating manner, and the upper part of the display cavity is communicated with a control cavity with an upward opening. According to the device, a centrifugal wheel abuts against an adjusting control rod, left-rightdeviation of a stroke pointer is achieved, the flow velocity condition of liquid flowing through the device can be timely and clearly reflected, meanwhile, a third gear is respectively meshed with afirst gear and a second gear, a valve plate can be automatically controlled to be opened and closed according to the change of the flow velocity of liquid flowing through the valve plate, the effect that the flow velocity of the liquid flowing through the valve plate can be automatically controlled to be within the set range is achieved, and the flow velocity can be easily set only by shifting theadjusting control rod.

Description

technical field [0001] The invention relates to the related field of novel valve bodies, in particular to a valve body device capable of automatically controlling the flow rate. Background technique [0002] At present, most of the valve bodies on the market have single functions and can only realize simple opening and closing functions. There are relatively large disadvantages in flexibility, and the use scenarios are greatly restricted. There are also many restrictions on the installation position and installation direction. The existing valves The body generally has a low degree of automation, and the flow rate is mostly controlled manually, which cannot accurately control the flow rate of the liquid flowing through it in real time, and cannot reflect the flow rate of the liquid passing through it in a timely, clear and intuitive manner. Contents of the invention [0003] The object of the present invention is to provide a valve body device capable of automatically cont...
