Description
Technical field
The utility model relates to a kind of flow device, relates in particular to a kind of intelligent flow controller.
Background technique
The self-controlled type flow control valve also claims self-balancing valve, flow control valve, flow dontroller, dynamic balance valve, flow balance valve, it is a kind of easy Flow-rate adjustment control gear directly perceived, using the self-controlled type flow control valve in the pipe network can be directly according to setting flow, valve can be under the water effect, automatically eliminate residual pressure and the caused flow deviation of pressure surge of pipeline, no matter how system pressure changes all keeps the setting flow constant, these functions of this valve are once finished the pipe network Flow-rate adjustment, transferring net work to become simple assignment of traffic, effectively solve the hydraulic misadjustment of pipe network.Self-operated flow control valve is mainly used in the central heat supply water systems such as (cold), makes the distribution according to need of pipe network flow, eliminates the water system hydraulic misadjustment, solves problem uneven in temperature, and 15%-20% can save energy, economizes on electricity.
The model utility content
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of control accurate intelligent flow controller.
The utility model is achieved through the following technical solutions:
A kind of intelligent flow controller, include valve body, the support cavity is installed above valve body, at valve inner valve base is installed, be sealed with the valve rod that moves up and down with valve base, described valve rod passes the support cavity, the valve rod below is equipped with silencing apparatus, Sound damping cover is equipped with in the described silencing apparatus outside, the silencing apparatus top is equipped with the water seal seat, be respectively equipped with seal ring between described Sound damping cover and silencing apparatus and the water seal seat, above the support cavity, Worm gear case is installed, be connected by nut between described Worm gear case and the valve rod, the nut below is equipped with thrust-bearing, described Worm gear case inside is provided with the worm and gear device, the worm gear below is equipped with Worm gear case gland and Worm gear case gland bearing, described Worm gear case gland and Worm gear case gland bearing seal assembling, the spline minor axis is installed in the middle of the described worm gear, the top of described valve rod is connected with spline minor axis in the worm gear by nut, on the described spline minor axis scale bar is installed, described scale bar is provided with electronic sensor, position locking device bearing and position locking device are installed above the spline minor axis, appliance mounting panel is installed in the middle of the described Worm gear case, in the Worm gear case outside motor cabinet is installed, the motor that is connected with worm screw is installed on the motor cabinet, at the Worm gear case opposite side meter housing is installed also, the meter housing internal controller is connected with appliance mounting panel.
The described Worm gear case outside also is provided with the handle that is connected with worm screw.
Working principle of the present utility model is: flow dontroller is finished the adjustment that pipeline is set flow automatically by the real-time instantaneous flow rate signal of the supporting electromagnetic flowmeter of sampling, by embedded microprocessor processing and Intelligent Control Strategy.In the mother liquor proportioning is used, can finish the quantitative proportioning of mixed solution automatically by mother liquid flow rate and the proportioning flow quantity of sampling simultaneously.When you partly import in embedded controller by man-machine interaction needed flow setting value or mixed solution proportioning parameter, flow dontroller just can be by comparing setting value and flowmeter sampled value, the closed loop control strategy of combined with intelligent, the autocontrol valve regulating mechanism is realized the accurate adjustment of flow.
The utility model has the advantages that: the utility model adopts the design of innovation mechanical structure, has transient equiliblium, and static auto-lock function adopts multi-stage sealed structure, can bear the highly pressurised liquid of 25.0MPa.Have faut detection and processing capacity, the assurance system is safe and reliable to operation.
