Embodiment
As shown in Figure 1, the invention provides a kind of liquid-adding device, it mainly comprises a sealing liquid supply box 20, first connecting tube 11, second connecting tube 12, the 3rd connecting tube 13, first pressure controlled valve 91, second pressure controlled valve 92, rotameter 30, outlet pipe 50, actuating motor 40, main frame, programmable logic controller (PLC) PLC, sealing liquid supply box 20 is by first connecting tube 11, first pressure controlled valve 91 is connected with external high pressure gas, 20 gas pressure is by 91 controls of first pressure controlled valve in the sealing liquid supply box, sealing liquid supply box 20 is connected with an end 34 of rotameter 30 by second connecting tube 12, the other end 35 of rotameter 31 is connected with outlet pipe 50, rotameter has the needle type valve 33 that can regulate its aperture, the aperture that rotation needle type valve 33 can be regulated rotameter 30, thereby the flow rate of liquid in the control rotameter 30, the flow velocity of liquid can show by the indicator window of rotameter (should write the concrete structure of rotameter exactly, what position indicator window is positioned at, and how to show).The needle type valve 33 of rotameter is connected with the main shaft 41 of actuating motor 40, drive needle type valve 33 rotations of rotameter 30 by the rotation of main shaft 41 of control actuating motor 40, thus thereby the flow of the flow velocity by liquid in the actuating motor 40 control rotameters 30 by liquid in the actuating motor 40 control rotameters 30.
Sealing liquid supply box 20 has sealing cover 21, sealing liquid supply box 20 is provided with pressure-relief valve 24, sealing liquid supply box 20 is connected with external high pressure gas by first connecting tube 11, first pressure controlled valve 91, thereby the pressure in the sealing liquid supply box 20 is by 91 controls of first pressure controlled valve.Sealing liquid supply box 20 is connected with an end 34 of rotameter 30 by second connecting tube 12.First connecting tube 11 is connected in pipe 22 places of sealing liquid supply box 20, and pipe 22 generally is connected in the top of sealing liquid supply box 20, and pressurized gas can enter in the close liquid supply box, keeps the liquid supply box internal gas to have certain pressure.Connecting tube 12 is connected in sealing liquid supply box 20 and extends to the bottom that seals liquid supply box 20 by managing 23, even the purpose of She Zhiing is under the lower situation of the liquid level of sealing liquid supply box 20 inside like this, liquid also can flow out by the 4th connecting tube 23, second connecting tube 12.Before use, opening the air that pressure-relief valve 24 will seal liquid supply box 20 the insides earlier drains, the liquid that the lid 21 of opening sealing liquid supply box 20 then will need to spray injects in the sealing liquid supply box 20, the liquid level 27 of control sealing liquid supply box 20 makes its about certain distance in top apart from sealing liquid supply box 20, this distance can make the inside of sealing liquid supply box 20 hold external pressurized air, and keeps certain pressure.Close sealing liquid supply box 20 then, open first pressure controlled valve 91 and make external pressurized gas slowly be full of sealing liquid supply box 20, sealing liquid supply box 20 gas inside pressure are by pressure controlled valve 91 controls.Owing to be filled with pressurized gas in the sealing liquid supply box 20, so-called pressurized gas are meant that its internal pressure is higher than barometric pressure, and the pressure difference between pressurized gas and the outlet pipe 50 can be so that the liquid of sealing liquid supply box 20 inside flows out smoothly from nozzle 51, and the pressure in the sealing liquid supply box 20 is generally greater than 1 barometric pressure and less than 10 barometric pressure.
Sealing liquid supply box 20 external pressurized gas, and by the constant pressure in first pressure controlled valve, the 91 feasible sealing liquid supply box 20.There is certain pressure in the sealing liquid supply box 20, there are pressure reduction in the inside and the outlet pipe 50 of sealing liquid supply box 20, pressure reduction makes the liquid in the sealing liquid supply box 20 flow into second connecting tube 12, rotameter 30, arrives outlet pipe 50, is flowed out through nozzle 51 by outlet pipe 50.When the pressure in sealing liquid supply box 20 makes liquid from sealing liquid supply box 20 inflow rotameters 30, because the liquid climbing power effect in the rotameter 30 of flowing through, with float 32 picking-ups of 31 li of glass tubes.When float 32 is raised to certain altitude, during the gravitational equilibrium of climbing power and float 32, float 32 just is stabilized in a certain height, and the gap of flow of liquid this moment between the wall of float 32 and glass tube 31 is with rated velocity V liquid feeding.When float 32 was stabilized in certain altitude, expression was with rated velocity V liquid feeding, thus the flow of energy basic controlling liquid.In general, under aperture one stable condition of the needle type valve 33 of rotameter 30, thereby the flow rate of liquid fluid flow by rotameter 30 is with the change in pressure in the sealing liquid supply box 20.When the pressure in the sealing liquid supply box 20 increases, by the also increase thereupon of flow rate of liquid of rotameter; When the pressure of sealing in the liquid supply box reduced, the flow rate of liquid by rotameter 30 also reduced thereupon.When other extraneous factor (as the variation in pressure of sealing in the liquid supply box 20), can be by regulating the aperture that needle type valve 33 is regulated rotameter 30, thereby adjust flow rate of liquid in the rotameter 30 by the aperture of regulating rotameter 30 and adjust fluid flow in the rotameter 30, make float 32 all-the-time stable at certain altitude, thereby promptly liquid pass through rotameter 30 with a constant flow velocity with a constant flow.
Rotameter 30 (claiming float flowmeter again) utilizes the principle of variable orifice and pressure reduction.Glass tube 31 inside of rotameter 30 are cone structure, and are up big and down small, and the main body of rotameter 30 (being glass tube 31) is vertical installs.Rotameter 30 utilizes the energy that flows to detect by flow rate of liquid, and rotameter 30 does not need external drive.Because the pressure reduction with nozzle 51 places in the sealing liquid supply box 20 exists, treat that fluid measured flows into rotameter from the inlet of rotameter, flow through vertical tapered glass tube 31 then from bottom to top, float 32 moves therein, can indicate flow rate of fluid according to the stable equilibrium position at float place by the flow detection parts.Constituted the circular crosssection between the internal diameter of the maximum outside diameter of float 32 with tapered glass tube 31, fluid flows through from this circular crosssection.When flow velocity increases, float 32 stands fluid upthrust from bottom to top will be increased, thereby be rushed at the top, and one arrives the top, because the cross section of circulation increases, flow velocity reduces, and upthrust also reduces thereupon.When upthrust and differential pressure to the active force of the section constitution of float 32 and viscous friction power etc. make a concerted effort with 32 of floats being equal in weight in fluid the time, float 32 promptly is in a state of equilibrium, no longer rises or descends, new flow speed value is just represented in this position.
According to the maximum rotating cycle N of the needle type valve 33 of rotameter 30 the maximum number of turns of rotation of actuating motor 40 is set, the maximum rotating cycle of actuating motor 40 is N.The initial point of actuating motor 40 is set.Actuating motor 40 can rotate in 0-N encloses scope, and actuating motor 40 is from 0 to N rotary course, and the aperture of rotameter 30 increases gradually, and the flow velocity of rotameter 30 increases thereupon gradually.When actuating motor 40 was positioned at initial point, the aperture of rotameter 30 was 0, and liquid can not pass through rotameter 30; When main shaft 41 rotations of actuating motor 40 drive needle type valve 33 rotations of rotameter 30, behind the main shaft 41 rotation N circles of actuating motor 40, the aperture maximum of rotameter 30, this moment is by the flow rate of liquid maximum of rotameter 30, and is also maximum by the fluid flow of rotameter 30.
Liquid-adding device can join liquid in the material of certain operation of main frame production line.In use, connect liquid-adding device, main frame production line and PLC power supply, the PLC initialization, zero point is determined that automatically PLC reads the absolute position of actuating motor encoder, and the correctness of effect readout in PLC pulse output.After system is ready to complete, the maximum number of turns of rotameter 30 rotations is set on man-machine interface according to the requirement of product, system calculates the absolute position of actuating motor automatically according to the maximum rotating cycle of the rotameter of setting 30, and both needle type valve 33 positions 0 to maximum rotating cycle N of rotameter 30 were corresponding with the analog signals of 0-10V.When the main frame production line is exported the analog signals of an actuating signal 0N and 0-10V to native system, system's actuating motor 40 rotates to the absolute position that calculates automatically, the needle type valve 33 that drives rotameter 30 rotates to corresponding position, thereby controls the flow rate of liquid in the rotameter 30 automatically.When the main frame production line stops (signal by ON to OFF), actuating motor 40 outputs stop, and start original point return automatically after 1 second.
When the main frame production line speeds up, Device Host is sent to PLC with real-time analog signals, PLC is through computing, output a control signal to actuating motor 40, the needle type valve 33 of actuating motor 40 control rotameters 30, increase the aperture of rotameter 30, making increases in proportion by rotameter 30 non-liquid feeding speed; In like manner, when the main process equipment running speed slows down, Device Host passes the signal to PLC, PLC is through computing, output a control signal to actuating motor 40, actuating motor 40 is controlled the needle type valve 33 of rotameters 30, reduces the aperture of rotameter 30, and feasible liquid feeding speed by rotameter 30 reduces in proportion.The present invention is according to producing needs, adjusting the needed flow quantity that adds at any time thereby adjust the needed flow velocity that adds at any time, to adapt to the different running speeds of main frame.
