Mechanical type 2 · Temperature control type 3. Electromagnetic type (alternating magnetic field). The mechanical control valve's application principle of 机械 ν valve is mainly man-made operation and oil pressure type control. It uses stop + cry to stop is (Stopper) opening and closing. Controls the flow of fluid. Although this type of control valve is called yell ..., its operation is stable, but because it has movable mechanical parts, it is easy to create and buckle μ ^ Do not become the following problems: (1) manual operation It is difficult to accurately control the flow rate of the metal fluid. Gates, μ miles, (2) This method is prone to leakage problems, and the accuracy of flow control is reduced. 丨 L β t ruggedness, y) Related parts such as stoppers are vulnerable to metal. The molten soup is eroded and damaged, making the molten soup pure affected. As for the / dish control type control valve is mainly used to change the liquid-solid phase interval caused by temperature changes to achieve the purpose of flow control, currently applying this principle are metal injection molding machines. The advantage is that it is stable and not limited to conductive fluids. The disadvantage is that if the temperature change interval between the two phases of the material is too large, the accuracy of the flow will be difficult to control. In the alternating magnetic field control unit / minute, its earlier form is as disclosed in the British Commonwealth No. GB-A-No.7772 丨 3, which uses a set of high-frequency coils that surround the fluid channel. After the high-frequency alternating current flows into the line, the coil will generate an alternating magnetic field to induce eddy currents on the surrounding surface of the metal flow. This induced current interacts with the magnetic field to produce a tight scale relative to the radial direction of the fluid. Applicable to Chinese national standards. (CNS) A4 rule 21〇x 29?

The following patent, U.S. Patent No. 4655237, added a refractory insert to the channel in the control valve of the above-mentioned patent form. Since the electromagnetic force presses the metal fluid to the center of the channel in a constricted manner, By placing the insert in the center of the channel, fluid leakage can be improved. However, although U.S. Patent No. 4,655,237 of the previous patent has improved the situation of incomplete fluid lockout, it caused the molten metal to solidify around the insert, thereby causing clogging. Based on this, Lillicrap of the United Kingdom proposed another patent, US Patent No. 4805669, which removed the original insert and changed the original circular outlet of the control valve to an asymmetric shape, which directly hindered the flow of molten metal. In this way, the blocking phenomenon of the previous patent is improved, and the closing function of the valve body is strengthened. Subsequent patents U.S. Patent No. 5 186886 and U.S. Patent No. 5 765 73 0 focus on the design of the valve body material and the composite form at the outlet of the molten metal soup. Such patents are mainly aimed at the traditional copper chill plug (copper chill plug). ) The valve body that performs the closing operation of the molten metal soup. Because this type of valve body is prone to cracks on the inner wall of the valve due to excessive temperature differences, a multi-layer anti-corrosion material design is adopted to improve the valve body due to thermal stress. . According to the comprehensive literature, the application of an alternating magnetic field to achieve the purpose of metal smelting soup will cause the following disadvantages: ⑴ high frequency (thousands of hertz) and great operating current, low energy efficiency; (2) in high-intensity magnetic fields and Under the action of electric current, the molten metal soup is locally overheated and the valve body parts are broken. Based on this, the present invention is based on basic theoretical analysis and experimental tests to test the Zuming, and proposes an electromagnetic complaint using a static magnetic field and a DC electric field. The control valve is caused by the interaction between the magnetic field and the electric field.

Description of the invention (6) ^ ~ For Zhi Ling, the conductive current can be strengthened by the Romitz force induced by the direct current. In this way, the purpose of making electromagnetic conductive flow control can be achieved. For the purpose of achieving high efficiency and easy control, the device of the present invention adopts the high-concentration energy hydrous magnet technology, and then uses the magnetic flux ring device to gather the magnetic beams in the conductive fluid tube of the control valve body to establish a stable and distributed high density. Harness the power. As shown in FIG. 2, in this embodiment, the design of a two-sided compact magnetic flux ring 6 is adopted. The upper magnetic flux ring 6 and the lower magnetic flux ring 6 are provided with a between each convex tooth. The magnet 8 leaves only the conductive fluid tube 3 between the central pair of convex teeth to pass through the valve body. This central pair of convex teeth can provide the effect of magnifying the magnetic flux density in the valve body. In the figure, the conductive fluid contained in the upper container 5 passes through the conductive fluid tube 3 and reaches the lower container 5 '. At this time, the flow direction of the conductive fluid will be orthogonal to the magnetic field between the pair of convex teeth in the center of the magnetically conductive ring 6 >, that is, a Lorentz force will be generated. In this embodiment, because the magnetic field between the pair of central convex teeth is set to S pole up and N pole down, the current j induced inside the conductive fluid is the direction flowing out of the paper, and the zombie force is formed. In order to prevent the conductive fluid from flowing down into the lower container 5, the direction. At this time, if the applied DC current is parallel and in the same direction as the induced current j, the Lorentz force generated is helpful and sufficient to intercept the flow of the conductive fluid. When the applied DC current is reversed, it helps the conductive fluid to flow down into the container. In Fig. 2, 7 is a thrust observation tube and 9 is a switch. Figure 3 shows the results of the compacted magnetic field lines produced by the two-sided compacted magnetically permeable ring 6 designed in this embodiment, which are plotted on the knot surface after computer calculation. It can be clearly seen from the figure Between the pair of central convex teeth (please read the precautions on the reverse side and fill out this page).

The long scale applies the Chinese National Standard (CNS) A4 specification (21〇). x297 mm) 6 16166 470835 A7 printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (7) The effect of increasing the magnetic flux density generated by the permanent magnet. If the valve body 1 is designed as a flat and narrow pipe, as shown in the cross-sectional view along the straight direction of the conductive fluid flow in Figure 4, where 10, a pair of electrodes are connected to a DC circuit, so that the static Magnetic field_I The electric field is completely orthogonal to produce the maximum Loyds force. In this embodiment, the conductive fluid 11 in the body ι is gallium (Ga), the electrodes 10 and 10 are made of steel, the container wall 12 between the magnetic poles is acrylic, and the fluid flow direction is perpendicular to the paper surface. It has been proved by experiments This kind of flat narrow pipe can achieve the purpose of cutting off the fluid and stopping it. In order to enable a wider range of applications, the valve body 1 is further designed as an annular flow passage valve body in another embodiment of the present invention. As shown in FIG. 5, the annular flow passage is formed by the inner and outer pipe bodies 13 and 13. The shape of this loop is mainly to maintain the flow situation as laminar flow. The inner and outer pipes 1 3, 1 3 can use graphite with a material with lower conductivity than metal fluids, which can force more applied current to flow through the conductive fluid inside the valve body to enhance the induced Lorentz force; in addition, silicon steel can be used. The material in the inner tube 13 can help the magnetic wire harness to gather in the center of the valve body, and at the same time can prevent the current from flowing through the fluid in the tube, and achieve better control effect. It can be verified through experiments that when the width of the loop is close to 1mm, the flow condition can be close to the cut-off state. If the DC current is continuously increased, the cut-off action can be achieved. The present invention can control the movement direction of the conductive fluid, so it can be further extended to be applied to the nozzle exit opening and closing device in the semi-solid metal injection molding technology. The number can be quickly reduced to a laminar flow state.

The present invention can also be extended to the second and last line: the device is manufactured only when the fluid-switching metal flows out of the nozzle outlet. Because of the Rotzing force of the surface tension of the molten metal, V causes the powder particles of the metal to be sputtered similar to the spark discharge effect. The present invention uses a static magnetic field and a DC snow field to generate Lorentz force to propel a metal fluid in a forward / reverse direction, which is different from the conventional 田 frequency alternating magnetic field used to generate magnetic fields to generate a Lorentz force. The effect of unidirectional interception of metal fluid; the magnetostatic medium% part of the magnetostatic medium adopts a double-side closed magnetically conductive ring design form, which can concentrate the network y ′ to concentrate the magnetic wire harness of the water magnet on the valve body of the control valve. Increase the magnetic flux density value produced by permanent magnets; the fluid flow of the flat narrow tube can be maintained in a laminar flow state, which can make the magnetic field and current completely orthogonal to generate the maximum Lorentz force, so it can suppress the conductive fluid Flow, and then reach the truncated state. The electromagnetic conductive fluid control valve of the present invention improves the shortcomings of the conventional alternating magnetic field type conductive fluid control valve that requires high-frequency and extreme current operation and low energy efficiency, and improves the conventional alternating magnetic field type conductive fluid control valve to high strength. The shortcomings of the magnetic field and the current will cause the metal solution to locally overheat and cause the carcass parts to break. Although the present invention has been described by way of examples, Ying Fengjie should not violate the broad spirit and viewpoints defined in the scope of the patents attached to the application of the present invention, and various changes or modifications should belong to the present invention.
