Definitions

  • This invention relates to valved water softeners; and it comprises a water softener having a multiple valve of the disk type allowing .the per formance in series of a plurality of phases of operation and having a plurality of passages therethrough, whereinsuch valve is provided with two members having correlated and coacting disk surfaces and beihgshiftable with respect to each other, the material/,of atleast one of the two members being of the nature of hard rubber; all as more fully hereinafter set forth and as claimed.
  • water softening apparatus using zeolites and similar minerals work in a number of successive phases.
  • the zeolites are exhausted, they are regenerated by a flow of salt water, this being either up or down, the spent-brine being sent towaste.
  • the final portions of brine going through are saved; going to a different conduit from the rest of the brine and used in the first stage of another regeneration. Afterwards, the salt water is rinsed out.
  • the apparatus After regeneration the apparatus is ready to soften hard water again. With upflow softening, the routine is much the same, save that the backwashing phase does not occur and the necessities for the regulation of rate of flow in other phases are somewhatmore exacting. With either type of softening, the minimum number of valved fiow passages is about five; and more are often used. Using separate valves, the multiplicity of valves to be opened and closed in a certain order,
  • valve with multiple ports and passages, this valve being connected to all of the supply lines and discharge lines. It ispossible. to design a single multi-port control valve with a "single movable valve memberadapted in various positions to establish successively the various combinations of connections, but. great difiiculties have been encountered in practice in attempting Of necessity, pressure requirements in the different Incidentally, the maze of pipe fittings and valves is ports are different and a given channel through a valve member may be used in several operathe main difiiculties is the fact that the valve must display extraordinary tightness against leakage in all positions, must be positive in its on and off service positions and must, nevertheless, be adapted to allow passage of a moderate amount of dirt or mineral matter.
  • valves having both port plate and rotating disk made entirely of hard rubber are particularly advantageous since they are cheap to manufacture, wear well and are non-corrosive.
  • valves adapted to the exacting requirements of a water softener can be constructed by making one of the co-acting elements of vulcanized hard rubber and the other of bronze or both ported and'channelled elements may be made of vulcanized hard rubber, one being backedby a rigid metallic member. With one element rubber and the other bronze, the latter gives rigidity, but with both of hard rubber,'an accessory metal stiffening plate is desirable with one but not both plates. Such a plate however is cheaper than a machined valve element.
  • Hard rubber is fully resistant to the corrosive action of water and brine. Furthermore, water is a lubricant for rubber and water is automatically applied to the surfaces requiring lubrica-' tion during use, thereby providing a low coemcient of friction for such surfaces. A further re duction of friction can be obtained by providing additional lubrication.
  • Liquid oils are not suitable for this purpose, and are, furthermore apt to cause rotting of the rubber, but certain heavy greases give good results; greases such as those known as bearing journal compounds. There can be used mutton tallow to which a preservative has been added, such as 1 to 2 per cent of sodium benzoate, in order to prevent decomposition.
  • Hard rubber is flexible, or rather, bendable, to some extent and in the course of time it may become set or permanently deform d under continuing stress and this, while a nuis ce in some relations, is convenient here, since it prevents interport leakage.
  • the relative movement of the two members increases from zero at the center of rotation to a maximum value at the periphery. Consequently, the wear is likewise greater near the periphery.
  • valve casing made of cast iron, brass or aluminum alloy.- Secured to this valve casing is a plateshaped member with. holes therein forming ports andconnecting with passages in the valve casing.
  • plate but movable with respect thereto is another plate with channels or passages adapted to establish various fiowcombinationsthrough the valve ports with various positions of the movable plate.
  • the valve casing is another plate with channels or passages adapted to establish various fiowcombinationsthrough the valve ports with various positions of the movable plate.
  • a stem connected with the movable plate for operation thereof extends through a stuiflng gland to the ou ide.
  • pla or both are made of hard rubber, and the Either the port plate or the movable.
  • other plate may be made of a metal advantageously a copper alloy of high hardness, such as phosphor bronze.
  • a metal advantageously a copper alloy of high hardness, such as phosphor bronze.
  • Hard rubber can be molded readily into plates with the required shape, provided with suitable passages or channels therein; the molded shape being afterwards machined if this is regarded as necessary. Where machining of a molded article is practiced it is'usually of only one side. I find it advantageous to finish the hard rubber contact faces by a machining operation in which a hard cutting tool is used. For this the metal known in the trade as Carboloy" is advantageous. Grinding with the use of an abrasive or "bufling compounds is not satisfactory, hard granules sometimes'becoming embedded in the rubber and inju'ring valve faces in operation, scoring and damaging the contact faces.

  • Valve disk 23 may be held against the port plate and the port plate in turn held against the body of the valve by means of the pressure of the incoming hard water.
