Definitions

  • the present invention relates to the introduction of magnetic couplings into valves for the metered delivery of products for pharmaceutical, food or suchlike uses, to allow quick disassembly, and subsequent quick reassembly, of the metered delivery devices located inside the valves, these operations being very frequent in order to enable the requisite conditions of sterility to be maintained in the processing of the products.
  • the prior art already includes metered delivery valves, some with a dual metered delivery system in which the first delivery system is coarse and takes the form of, for example, a throttle valve occupying the entire aperture of the valve body, while the second, which is formed within the body of the first, is of smaller dimensions and variously constructed, its control being independent of the coarse system.
  • shutoff members in existence as they do not form the subject of the invention.
  • the explanation of the invention will therefore be limited to the case of a valve in which the shutoff condition is provided by single and double throttle valve systems, as what is said of these cases may also be extended to any other situation.
  • the object of the present invention is to enable the above operations to be carried out by one person.
  • the invention as characterized in the claims solves the problem of enabling one person to bring together the two surfaces and unite them by the simple force of attraction of the permanent magnets.
  • Fig. 1 shows the longitudinal cross section through a shaft (1) that accommodates, in its end, a permanent magnet (m) inserted in a circular annular groove with its magnetic axis coinciding with the axis of the shaft, as shown in Fig. 2.
  • the method by which the magnet is fixed in the circular annular groove depends on the type of material of the shaft: if ferromagnetic, fixing is by the attraction of each permanent magnet, whereas if of diamagnetic material, such as stainless steels or plastic materials, the groove must be closed with, for example, a washer (v) welded or screwed into place, or secured by some other system.
  • Fig. 3 shows lengths of shaft (1) and (1') joined magnetically: it is self-evident that the polarities of the opposing permanent magnets must be of opposite sign.
  • Fig. 4 shows the application of the invention to a shaft with a flange (2).
  • Sheet No. 2 shows the application of the above principles to a valve used for the metered delivery of granular, powdered or suchlike products employed in the pharmaceutical or food industry, and consists of a cylindrical body (3).
  • the valve is of the double throttle-valve type, this being the configuration of the product shutoff members, namely that (4) occupying the entire cross section of the valve body, and that (5) occupying a central portion of the previous member and enabling finer control of the delivery of the product.
  • valves with single or dual shutoff members of any other type can be transferred to valves with single or dual shutoff members of any other type, as will readily be appreciated from a perusal of the rest of the description.
  • Fig. 5 of sheet 2 depicts the control shaft (6) of shutoff member (4), and the control shaft (7) of shutoff member (5), these shafts being made up of segments held together by the magnetic coupling described earlier, and the two rings (8) and (9) connecting the valve to the rest of the system, which are also made integral with the body (3) of the valve by magnetic coupling.
  • FIG. 6 shows the valve seen from above.
  • Fig. 7 of sheet 3 shows the longitudinal section through the valve on a plane normal to that of the section seen in Fig. 5 in sheet 2 illustrating the same components and with the two adapter rings (8) and (9) detached from the body (3) of the valve.
  • Fig. 8 shows the valve seen from above.
  • Sheet 4 shows a possible embodiment of the invention in a case in which the valve body (3) consists of two separable half-bodies (3') and (3'') plus, in order to keep the drawing simple, a single shutoff member, although the conclusions arrived at can also be applied to the case of a dual shutoff member.
  • the shaft interruption may be located outside of the valve body as well as inside it, as in the case described previously, with flanged or unflanged shafts.
  • Sheet 4 indicates a possible embodiment of this type of valve with a flanged shaft.
  • Figs. 9 and 10 show two mutually perpendicular longitudinal sections through the valve showing the shaft (6) with flanges (10) containing the permanent magnets (m5) for their coupling.
  • Fig. 11 shows the top-down view of the half-body (3') of the valve, in which the electromagnet (6) placed in the circular annular groove in the half-body (3') of the valve can be seen, this groove now of course being interrupted at the bushes (11). All the other indications refer to parts already described earlier, including the permanent magnets (m3) and (m4) for coupling with the adapter rings (8) and (9) (not shown). In this case the interruption of the shaft (6) may be located outside of the valve body (3) in order to allow dismantling of the shutoff members after the two half-bodies (3') and (3'') have been separated.
