Description of drawings
Fig. 1 is the structure diagram according to a kind of flow-control equipment of the present utility model;
Embodiment
To explain an exemplary embodiment of the present utility model below.
Several fluid flow control devices of the present utility model comprise: inlet, outlet, the pressure regulating part branch, the control valve for fluids part, flowmeter, ratemeter, controller and negative and positive connector, described entrance and exit is positioned at the two ends of fluid flow control device, the pressure regulating part branch is positioned at fluid flow equipment top, control valve for fluids partly is positioned on the fluid flow control device, flowmeter and ratemeter lay respectively at left part and the right part in the fluid flow control device, respectively have a female connector and a male connector on described each fluid flow equipment, described the moon, male connector lays respectively at the left side of each fluid flow equipment, right both sides.Several fluid flow control devices connect by the negative and positive connector on it.Wherein, also comprise bus module, it is configured to make system to be communicated with a control module.Each fluid flow control device also comprises the display that is used to show rate of flow of fluid and flow.
Fig. 1 shows the embodiment of the fluid flow control device that comprises inlet 120 and outlet 125.120 fluids that enter the mouth are connected in fluid source 80, and are configured to allow fluid to enter fluid flow control device 5.Fluid can be liquid, slurry or gas form, can have low relatively viscosity and relative low reactivity.Fluid flow control device 5 can comprise further that controller 115, one pressure regulating parts divide 10, flowmeter 25 and flow control valve portion 30.Pressure regulating part divide 10 comprise pressure governor 15 and regulator pilot valve 20 and be configured to accept fluid flow and with controlled pressure transmission fluid.Pressure governor 15 can be used for the pressure that controlled pressure is regulated the downstream fluid of part 10, can make response to the downstream pressure of the fluid by backfeed loop.Pressure governor 15 can be a valve adjuster that is configured to pneumatic control.But regulator pilot valve 20 fluids fluidly are connected to supercharging substance source 65 (not drawing among the figure), regulator pilot valve 20 may command supercharging materials from substance source 65 to regulator 15 supercharging flow, with pneumatic actuation regulator 15, and make regulator 15 set up the specific hydrodynamic pressure in regulator 15 downstreams.Regulator pilot valve 20 can accept the electric signal of self-controller 115, and according to this electric signal, makes pressure governor 15 be driven to corresponding degree, and with the supercharging material of supply specified pressure, the driving pressure regulator 15 thus.Pressure governor 15 responds the supercharging material by its aperture or other passage being opened to corresponding degree, regulates the pressure that pressure regulating part divides 10 downstream fluid thus.Therefore, the downstream fluid of pressure governor 15 has a pressure that is arranged.
As shown in Figure 1, the control valve for fluids part 30 of fluid flow control device 5 can comprise the flowrate control valve 35 by motor 40 controls.Flowrate control valve 35 can be accepted pressure at the fluid of regulating under part 10 controls, and works as fluid from the flow velocity of flow-control equipment 5 through out-of-date adjustable body.In some example, the motor 40 of control control valve for fluids 35 accepts the electric signal of self-controller 115, and according to this signal mechanically driver's valve 35 with the control rate of flow of fluid.Fluid flow control device 5 also can comprise flowmeter 25.After fluid is with the pressure discharge pressure regulator 15 that is arranged, the flow velocity of the fluid upstream of flowmeter 25 measurable flow body operation valves 35.Flowmeter 25 can be with first-class measurement amount signal conveys to controller 115.Controller 115 can divide 10 and the flow control valve portion according to measured flow speed control pressure regulating part.
Display 135 can show the required flow rate of input, the flow velocity of measurement (being measured by flowmeter 25), and display 135 can be LCD or the display device that is used for any other type of output information, but is not limited thereto.
The advantage that this equipment has has: can be accurately and repeat to control the flow velocity of fluid; Between the detection of the change of flow velocity and this change, there is not a certain amount of hysteresis; Simple in structure easy to operate, the accuracy height, cost is low.
