In Fig. 1, a flow control valve of the present invention is used for making emulsions equipment.In this equipment, gel solution is housed in the reaction tank.KBr solution and AgNO3 solution join in the gel solution with proper speed.Halide ion Br-in KBr solution and the silver ion Ag+ in AgNO3 solution react to each other, and generate bromide silver (AgBr) emulsion.Notice, except KBr solution, also can use the alkali-metal solution of other halogen, for example NaCl and KI.Halide ion Cl-and I-and silver ion Ag+ reaction generate the silver emulsion of AgCl and AgI, also may generate two or more silver halides.
KBr solution provides from the liquid pool (not shown) by pump 11.The KBr flow of solution is crossed first flow modulating valve 12 and is joined in the gel solution in the reaction tank 10.Measure the flow of KBr solution by flowmeter 13.AgNO3 solution provides from the liquid pool (not shown).The AgNO3 flow of solution is crossed in the gel solution that second flow control valve joins reaction tank 10.Measure the flow of AgNO3 solution by flowmeter 17. Flow control valve 12 and 16 opening area change by the motor 21 and 22 that is driven by controller 20 respectively.Flow to the fluid flow of reaction tank 10, promptly the amount of fluid in the unit time is adjusted. Flow control valve 12 and 16 the detailed structure description of face as follows.
Flow to the flow of the KBr solution the gel solution in 13 unit of measurement's times of flowmeter from flow control valve 12.Flowmeter 13 sends the flux signal of a KBr to controller 20 according to the flow that records.Flow to the flow of the AgNO3 solution of gel solution in 17 unit of measurement's times of flowmeter from flow control valve 16.Flowmeter 17 sends the flux signal of an AgNO3 solution to controller 20 according to the flow that records.

When making emulsions, if fine grain size of AgBr or crystal state (said in the field of crystals " habit ") change, the granularity of the photosensitivity of film or image will change.AgBr coating of particles, size and similarity can change, and this depends in emulsions manufacturing and the ripening process density PAg of silver ion in the gel solution.In reaction tank 10, be placed with density detector 25 or electrometer or sensor, be used for measuring the density of the silver ion in the reaction tank gel solution.Density detector 25 produces a density signal according to the density value that measures, and density signal is sent to controller 20.
In Fig. 2 and Fig. 2 A, a control valve unit 30 of flow control valve 16 has been described.Control valve unit 30 comprises the valve rod 32 of a valve body 31 and a circle.Valve body 31 is made up of valve chamber 33 that closely links to each other and outlet valve block 34.Between valve chamber 33 and outlet valve block 34, form a valve pocket 35 or clack box.Form an inlet 36 in valve chamber 33, by this inlet, AgNO3 solution flows into valve pocket 35.Form an outlet 37 on outlet valve block 34, by this outlet 37, the solution in the valve pocket 35 flows out.Outlet 37 and valve rod 32 co-ordinations, the flow that regulator solution flows out.
Suppose that outlet 37 has a length L, the outflow direction with respect to vertical solution has the length greater than L to valve pocket 35 in outlet 37 back.Valve pocket 35 holds valve rod part 42 by inlet chase 41 and one second and forms.Inlet chase 41 is connected with inlet 36.Inlet chase 41 comprises that one first is held the valve rod part.Second holds valve rod part 42 is connected with outlet 37.
Second holds valve rod part 42 space, be connected with outlet 37 by this space inlet chase 41, in as the internal surface of valve seat 44 also as valve chamber 33 with export the sealing surfaces of valve block 34.Valve rod 32 is inserted into a side of valve body 31 by a sleeve 45, and valve rod 32 holds in the post part 42 longitudinally-slidable along outlet 37 second.The mobile mechanism that back will be described makes valve rod 32 slide between fully open position and complete shut-down position.When at fully open position, thus valve rod 32 from valve pocket 35, withdraw to open out port recess 37b and second and hold valve rod part 42 and be connected, when in the complete shut-down position, cover the whole port recess 37b of going out, hold valve rod part 42 to close second.
In Fig. 3, valve arrangement 30 is with the formal specification of sectional drawing.Valve rod 44 has the spill of a bending, and diameter equals the diameter of valve rod 32.The circular surface of valve rod 32 closely contacts with valve seat 44.Therefore, can prevent that the solution that riddles in the inlet chase 41 from flowing out to outlet by valve rod 32 and valve seat 44.The height of the opening of inlet chase 41 makes valve rod 32 closely contact with valve seat 44 less than the diameter of valve rod 32, and prevents the end shake of valve rod.
The width of outlet 37 promptly goes out the diameter of the width of port recess 37b less than valve rod 32.When valve rod 32 holds in the valve rod part 42 when sliding second, increase in proportion or reduces at second opening length of going into port recess 37b or the A/F that holds valve rod part 42 in, so be proportional to the valve opening area from the flow of the fluids that export 37 outflows.Have flow control valve 16 simple in structure of valve arrangement 30, can produce in batches.Flow control valve 16 requisite spaces are installed to be reduced.
The smooth surface of valve rod 32 and valve seat 44 makes the slit can not occur between valve rod 32 and valve seat 44.The width of outlet 37 is vertically to keep constant along outlet in 3% accuracy rating in the error that allows.Therefore can guarantee the linear relationship between valve opening area and the flow.Notice valve rod 32 be one cylindrical, but also can be one plate shaped or prismatic.Consider sealing and operability, valve rod 32 is preferably cylindrical.
In order to realize the repetition High Accuracy Control to the valve rod position, valve rod 32 comes the slide adjusting valve opening area by a mechanical structure among Fig. 4 A and Fig. 4 B.This mechanical structure comprises a motor 22,52, slide plates 53 of axle and a guide rod 54 that makes the transfer mechanism rotation.Motor 22 for example is a kind of servomotor, by controller 20 controls.Axle 52 has a ball screw thread 52a, axially links to each other with motor 22.Slide plate 53 has a box thread 53a, and 52a matches with the ball screw thread.One end of valve rod 32 links to each other with slide plate 53.Guide rod 54 is regulated the slip of slide plates 53, makes slide plate 53 endwisely slipping along axle 52 or valve rod 32.Ball screw thread 52a and box thread 53a and transfer mechanism cooperating.
Notice that slide in order to make valve rod 32, other mechanical structures can be used for the slippage of valve rod is accurately regulated.For example, the corner of a motor can be by a rotation decoder measuring.The rotation of motor can convert straight line motion to the modulating valve opening area by a rack and pinion mechanism.
The material of the material of valve body 31 and valve rod 32 can be selected suitable material.Valve body 31 preferably uses the different material of hardness with valve rod 32, becomes and can not move between valve body 31 and the valve rod 32 preventing.Also to consider the precision of material work when selecting material, prevent because to be conditioned below the corrosive action of fluid solution be valve rod 32 and the example of the combination of the material of valve body 31: pottery/stainless steel; Titanium alloy/pottery; Stainless steel/chromium plating stainless steel.
Operation of the present invention is described below.Come the KBr flow of solution inflow-rate of water turbine modulating valve 12 and the flowmeter 13 of self-pumping 11, join in the gel solution of reaction tank 10.Come the AgNO3 flow of solution inflow-rate of water turbine modulating valve 16 and the flowmeter 17 of self-pumping 15, join in the gel solution of reaction tank 10.Ag+ in Br-in the KBr solution and the AgNO3 solution reacts to each other, and generates AgBr or bromination silver salt or halogen silver salt.
When the variation that detects the density of the silver ion Ag+ in reaction tank 10 when controller 20 departs from predetermined allowed band, the flow in the unit time of controller 20 calculating K Br solution and AgNO3 solution so that the density PAg of silver ion remain unchanged.According to result calculated, controller is determined the information of the valve opening area of flow control valve 12 and 16.And controller 20 is according to the information of the valve opening area of flow control valve 12 and 16 and sense of rotation and the angle of swing of determining motor 21 and 22 from the flow in the unit time shown in the flux signal of flowmeter 13 and 17.
When silver ion density surpasses a reference value, determine that the sense of rotation of motor 21 and angle to enlarge the valve opening area of flow control valve 12, improve the adding speed or the flow of KBr solution.The sense of rotation of definite motor 22 and angle reduce the adding speed or the flow of AgNO3 solution to reduce valve 16 opening areas simultaneously.
In the flow control valve 16 of AgNO3 solution, motor 22 rotation makes valve rod 32 slide to closed position, is positioned the position that information determined of the valve opening area determined by controller 20.The opening area that goes out port recess 37b reduces according to the slippage of valve rod 32, to reduce the valve opening area.The AgNO3 solution that flows through flow control valve 16 reduces.As a result, the AgNO3 solution that joins in the reaction tank 10 reduces.
When controller 20 is considered the valve opening area and when regulating flow control valve 16, controller 20 monitorings are from the flow of the AgNO3 solution of flowmeter 17.Thereby produce a servocontrol.If the flow of AgNO3 solution does not also reach predetermined amount of flow when flow control valve 16 places a predetermined open position, the valve opening area will be adjusted.
Simultaneously, motor 21 rotations increase the flow of KBr solution to enlarge the opening area of flow control valve 12.Monitoring produces a servocontrol of motor 22 from the flux signal of the KBr solution of flowmeter 13, thereby regulates the valve opening area of flow control valve 12.Therefore the density of silver ion maintains on the predetermined level.
If the density PAg that detects the silver ion in the gel solution is less than reference value, motor 22 rotations make valve rod 32 slide to the standard-sized sheet direction, increase AgNO3 solution and join flow in the reaction tank 10.Simultaneously, motor 21 rotations reduce the flow of KBr solution to reduce the opening area of flow control valve 12.Monitoring from the flux signal of flowmeter 13 and flowmeter 17 to regulate the flow of KBr and AgNO3 solution.Motor 21,22 can servocontrol be regulated, and regulates the valve opening area of flow control valve 12 and 16 respectively.
In flow control valve 16, the outflow direction of the vertical and solution of outlet 37 intersects.The shape that has the outlet 37 of valve rod 32 should prevent out that the non-stationary flow at the edge of port recess 37b occurs.Therefore, can obtain good proportion or linear relationship between valve opening area and the flow.Even flow repeats or flip-flop, the reacting dose of Flow-rate adjustment is also very high, because flow can reset reliably along with the variation of opening area.If AgNO3 solution carries out Flow-rate adjustment in low especially scope, flow also can be accurately and appropriate regulation.Proportional increase or the minimizing along with the variation of the corner of motor 22 of valve opening area is to realize Flow-rate adjustment.As a result, by top simple adjustment, the flow that joins the AgNO3 solution in the reaction tank 10 can correctly be regulated.Therefore the load of controller 20 is very little.The effect of flow control valve 16 is equally applicable to flow control valve 12.
Respectively the flow of KBr and AgNO3 solution is monitored by flowmeter 13 and 17.According to the flow that records and the density measurement of prober 25 flow control valve 12 and 16 is regulated.Thereby can accurately regulate the flow of KBr and AgNO3 solution.
In the above embodiments, KBr solution and AgNO3 solution are carried out Flow-rate adjustment.The present invention can regulate other solution, liquid or fluid equally.In each valve, the importer of solution is to identical with the Way out of solution in the above.In the present invention, the Way out of valve also can be angled with Way in.
In the above embodiments, gel solution is as the Bond in the manufacturing of the emulsions that contains the halogen silver salt.Also can select other Bond, for example, polyvinyl alcohol also can be used for making emulsions.
