Abstract
The utility model discloses a valve flow alarm control system, which comprises a valve and a controller and also comprises a liquid level sensor, an alarm module, a flow velocity controller and a valve driver, wherein the liquid level sensor is used for detecting liquid level in a liquid chamber to generate liquid level data; the flow velocity controller is used for controlling flow velocity of the valve; the valve driver is used for controlling closing and opening of the valve according to the received control information; the liquid level sensor and the alarm module are connected with the controller; and the controller is sequentially connected with the valve through the flow velocity controller and the valve driver. The valve flow alarm control system is novel in design, the liquid level and flow velocity detection and valve control are simultaneously processed, and the system is high in processing speed and high in real-time property, has an alarm function and brings great convenience to actual production and use.
Description
Technical field
The utility model relates to a kind of valve control system, relates in particular to a kind of valve flow alarm control system.
Background technique
In self-elevating drilling platform uses, for preventing in drilling process because the platform load increases serious accident and the loss that causes spud leg to sink, so must not carry out pre-ballast operation before behind platform pitching pile leg, rising to design height.Pre-ballast usually adopts and inject seawater in the load of platform cabin, generally can consider the volume of compartment of the even ballast of each spud leg and can use some other cabin (potable water tank etc.) to reduce the shared unnecessary space of ballast tank and quality when Platform Designing; Select the data of pre-ballast very important, it must be greater than the maximum actual load that in the whole operation process of platform each spud leg is applied; Can not to leave the water surface too high for hull during pre-ballast operation, in case certain spud leg sink suddenly and causes the crooked of platform even tumble.
Can utilize the valve of valve switch ballast tank, realize the control of seawater turnover, monitor cabin liquid level (weight) with liquid level sensor, after in case ballast water reaches desired value in the cabin, turn off at once inlet valve, thereby what of control ballast water make the ballast effect reach desired value, the ballast that so just can well expect to platform.Valve remote control and remote tank gauging system plays critical effect at load of platform.Except load of platform can be used this system, use equally in bilge-water, fire fighting water system, fuel oil tank system etc.
But prior art detects for liquid level and valve control is separately carried out.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of valve flow alarm control system.
To achieve these goals, the technical solution adopted in the utility model is: a kind of valve flow alarm control system, comprise valve and controller, and also comprise liquid level sensor, for detection of the indoor liquid level Generation Liquid bit data of tank; Alarm module, flow speed controller are used for the control valve flow velocity; Valve driver is used for closing and folding according to the control information control valve that receives; Liquid level sensor links to each other with controller with the alarm module, and controller links to each other with valve with valve driver through flow speed controller successively.
As preferably, controller is the DSP DSP digital signal processor.
Compared with prior art, the utility model has the advantage of: modern design, to process in the time of liquid level and flow rate detection and valve control, processing rate is fast, and real-time is good, also has warning function, and it is greatly convenient to have brought for people's actual production use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of mode of execution of the present utility model, consult Fig. 1, the utility model comprises valve and controller, also comprises liquid level sensor, for detection of the indoor liquid level Generation Liquid bit data of tank; Alarm module, flow speed controller are used for the control valve flow velocity; Valve driver is used for closing and folding according to the control information control valve that receives; Liquid level sensor links to each other with controller with the alarm module, and controller links to each other with valve with valve driver through flow speed controller successively.Controller is the DSP DSP digital signal processor.
The utility model is novel in design, processes in the time of liquid level and flow rate detection and valve control, and processing rate is fast, and real-time is good, also has warning function, and it is greatly convenient to have brought for people's actual production use.
Although be recognized as a most practical and preferred embodiment and described the utility model in conjunction with current, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
